SAFETY INFORMATION

Use caution when working with the

Auger--springing auger may cause personal injury.

CAUTION

Selecting the System . . .

CHORE-TIME Feed Delivery systems are designed to handle most common

livestock and poultry feeds. We can not guarantee satisfactory operation

with all formulations. We suggest that you contact our Technical Service De-

partment concerning the use of new or unusual formulations.

FLEX-AUGER Feed Delivery Systems are the most versatile feed conveying

systems available. Their ease of installation, reliability, low maintenance,

and adaptability for many different applications, make them an indispens-

able part of any livestock feeding system.

The FLEX-AUGER Feed Delivery System you choose should be based on the

following;

1. Particle Size - Feed particles that are too large for the system will cause

damage to the particles, excessive power requirements, and plugging of

the system.

2. Moisture Content (18% maximum) - The moisture content of the feed,

among other factors, determines the amount of buildup that will occur on

the auger and auger tubes when conveying feed. Feeds with high mois-

ture content (above 18%) will freeze if exposed to freezing temperatures.

This type of feed tends to flow less-easily causing higher power require-

ments. Feeds in High Moisture Corn applications should not exceed 27%

moisture content.

3. Feed capacities - Each size of FLEX-AUGER delivers feed at a different

rate. These rates should be matched to your feed requirements. An ap-

plication that requires a large volume of feed to be moved should use a

larger (i.e. Model 90 or HMC) auger system or possibly two smaller auger

(i.e. Model 55 or 75) systems. See page 7 for System Comparison infor-

mation.

4. Running Time - Size the system so that the maximum operating time is

four hours per day (24 hours). If necessary, refer to the Livestock & Poul-

try Feed Consumption chart on page 63. If your system operating times

exceed four hours per day, contact your distributor or Chore-Time’s

Technical Service Department.

NOTE: The maximum allowable liquid molasses content for all FLEX-AUGER

Feed Delivery Systems is 2%. At higher liquid molasses content or at mois-

ture levels above the recommended limits, the auger tubes can become

coated. This reduces the carrying capacity of the feed delivery system,

causing eventual plugging of the system.

Caged layer applications require the use of all steel FLEX-AUGER Feed De-

livery Systems. Hardened steel elbows are required for these applications.

This is due to the abrasive feed particles in caged layer feed rations. Do not

mix steel and PVC components within a system.

Adequate support must be provided to prevent the tubes from sagging and

support the weight of the Control Unit. The auger, tubes, and feed weigh ap-

proximately 6 lbs/ft. (9 kg/m). The Control Unit weighs approximately 80 lbs.

(36 kg).

Line lengths specified allow for two 45 degree elbows in the elevation. Re-

duce line length by 30’ (9 m) for each additional horizontal 90 degree elbow.

For Tandem Systems, raise the horsepower one size over recommendations

in the table below or reduce line length by 50’ (15.4 m).

Note: If voltage supplied is 208V, reduce the line lengths by 20%.

Horsepower requirements are based on length of the FLEX-AUGER System

and type of system installed--number of turns, tandem systems, etc. The

charts included show maximum line lengths for FLEX-AUGER Systems plus

maximum lengths for systems using Extension Hoppers. Refer to the Exten-

sion Hopper instruction (MA709, Model 55, 90, & HMC systems only).

The 30 Degree Boot (left) is the standard boot

used in single bin applications.

The Straight-Out Boot (right) may be used in

multiple bin applications, elevated bins, and sys-

tems with less free flowing feed stuffs.

The Hopper Level

Control is used to

control the feed level

in the hoppers.

The Control Unit

(right)

is located at

the end of the fill sys-

tem. A Power Unit

(left)

is secured to the

Control Unit to turn

the auger.

An Extension Hopper (optional) may be used

to provide additional length to a system. Multi-

ple Extension Hoppers may be used on very

long systems. Refer to the chart on page 7 for

maximum line lengths.

An Outlet Drop is located at each outlet opening

along the FLEX-AUGER auger line.

The Drop Tube Switch (optional) is mounted directly be-

low the Control Unit. Two versions of the Drop Tube Switch

are available: Mechanical (left) and Proximity (right).

The 30 Degree Two Motor

Tandem Boot (optional) is

used when a cross auger is

required under two feed

bins. This allows the feed

bins to be set at a 90 degree

angle to the FLEX-AUGER

feeder line.

Glossary of Terms

The Auger Timer (optional)

is used to control the length

of auger run-time. It may be

used as a safety backup to

prevent excessive run time.

The Lower Boot Com-

ponents, located under

the feed bin, include a

bearing and feed re-

stricting device.

FLEX-AUGER Installation & Operator’s Manual •

Page 9

See pages 10 - 13 for typical FLEX-AUGER installations. When laying

out the FLEX-AUGER Feed Delivery System, plan the system so that

the auger tubes do not interfere with doors, windows, or other equip-

ment.

See page 14 for typical Bin-to-Building Placement Chart using various

elevations and boots.

1. For the easiest installation and most trouble-free operation, locate

the feed bin in a direct line with the FLEX-AUGER Feed Delivery

System. The layout chart on page 14 provides some points of refer-

ence for bin placement according to the height at which the

FLEX-AUGER tube enters the building. Remember, these are only

examples. The layouts can be modified by changing the elbows, the

tube sections, and/or the distance from the bin to the building.

Locate the bin so that the FLEX-AUGER Feed Delivery System does

not have to convey feed at an angle of more than 60 degrees from

the horizontal to enter the building at the desired height.

Chore-Time considers a 45 degree elevation to be standard--the

lower the angle, the more reliable the system.

2. Lay out the system as straight as possible. Avoid extra elbows and

curves by locating the feed bin in line with the feeders. One hori-

zontal 90 degree turn is permissible inside the building. 180 degree

turns are not recommended under any conditions.

If additional turns or elbows are required, use extension hoppers.

Remember: one 90 degree elbow requires the same power as 30’

(9.1 m) of straight line.

3. Plan the system so that the auger tubes are directly over the feed-

ers or hoppers to be filled as possible. The drop tubes may be an-

gled up to a maximum of 45 degrees from the vertical if necessary.

At angles greater than 45 degrees, bridging in the drop tubes may

occur.

4. The control unit must be located over a feeder or hopper that will

require as much or more feed than any of the other feeders or hop-

pers. If frequent filling is desired, mount the drop tube switch or

hopper level switch low so that this feeder or hopper will have a low

feed level. This causes the feeder to call for feed more often, the

system will restart, and the other feeders will be refilled sooner.

5. Do not locate outlet drops on or just before an elbow. Install the

drop after the elbow so feed will cushion the auger through the

curve. If there is some reason why the outlet drop cannot be moved,

it must have some “feed bypass” to cushion the auger through the

elbow.

6. Avoid horizontal left-hand turns if possible. The elbow in a left-hand

turn is not cushioned by the feed and will wear faster. On systems

with a 90 degree horizontal left-hand turn, reduce the stretch to re-

duce wear.

NOTE: A rule of thumb for left-hand turns is to reduce stretch to 1"

per 50’ (25 mm per 15.2 m) on initial installation. Increase the

stretch if necessary.

Planning the FLEX-AUGER System

FLEX-AUGER Installation & Operator’s Manual •

Page 10

If an extension hopper is used:

A. Locate the hopper so there will not be any outlet drops on the

short tube or elbow leading out of the hopper.

B. The longer portion of the system with most of the outlet drops

should follow the extension hopper. For example: in a 300’ (91.4

m) Model 75 System the distance from the bin to the extension

hopper should be 100’ (30.5 m). From the extension hopper to

the control unit should be 200’ (61 m) with most outlets placed

on the 200’ (61 m) section. Refer to chart on page 7, for power

unit requirements.

C. NOTE: The lower part of the extension hopper can be turned 90

degrees to the left or right in relation to the top portion of the

extension hopper. This allows the extension hopper to replace a

horizontal elbow where both might be located in approximately

the same position in the system.

7. Remember the following points when installing a Straight-Through

Tandem System or Two Motor Tandem System:

A. The straight-through tandem bin arrangement uses one continu-

ous auger.

B. The Two Motor Tandem bin arrangement uses two separate au-

gers and power units.

C. Pour one level concrete pad for both bins (in either system).

D. Position bins so that legs will not interfere with the FLEX-AU-

GER System (in either system). See the Two Motor Tandem Sys-

tem instructions (MA524, Model 75, 90, & HMC systems only).

8. Use the chart on page 7 to determine maximum line lengths and

power unit requirements.

Typical System Installations

The FLEX-AUGER Delivery Systems may be readily adapted to most

feed delivery applications. The systems illustrated on the following

pages show the most common types of FLEX-AUGER installations.

These diagrams provide guidelines for laying out your system.

Four systems that are not recommended are shown on pages 12 & 13.

Possible alternate systems are provided with each non-recommended

system.

System A represents a typical straight-line system with optional tan-

dem bin setup. If this were a long system with many outlet drops,

some feed bypass should be provided by increasing the size of the

outlet holes, from small at the bin end, to the large at the control

end of the line.

FLEX-AUGER Installation & Operator’s Manual •

Page 11

System B represents an extended length system. Equalize the power

requirements of each part of the system. Optional equipment required.

System C utilizes right-hand and left-hand 90 degree turns. The eleva-

tions should be accomplished within the elbows.

System D utilizes right-hand 90 degree turns. The elevations should

be accomplished within the outside elbows. This system would be

recommended over system E since it eliminates additional elbows

and left hand turns.

System E uses one additional 90 degree elbow after entering the build-

ing. Note that the elbows are left-hand turns. This system would be im-

proved if the feed bin were moved to the opposite side of the building

to provide right-hand turns instead.

FLEX-AUGER Installation & Operator’s Manual •

Page 12

System F represents a circulating feed delivery system with optional

bin placement. This system is used where a continuous supply of

feed is needed or when it is difficult to use a control switch. Optional

equipment required.

System G represents an extended length system with one additional 90

degree elbow. This is acceptable, but Systems C or D would be recom-

mended (to reduce excessive run time). Optional equipment required.

NOT ALLOWED. System I is not recommended, due to 180 degree,

left-hand turns. Excessive elbow wear and erratic auger operation

would be expected. Systems D, E, or G would be recommended.

NOT ALLOWED. System H is not recommended, due to 180 degree,

left-hand turns. Erratic auger operation would be expected. The feed

bin should be relocated or an Extension Hopper should be utilized as

in System G.

FLEX-AUGER Installation & Operator’s Manual •

Page 13

NOT ALLOWED. This system uses 180 degree elbows and would be

subject to premature elbow wear due to outlet drop placement before

an elbow. System C would be recommended.

NOT ALLOWED. Too many elbows. The result would be auger vibration,

motor stall, and excessive elbow wear. A twin system, such as C, D, or

E, would be recommended; or an Extension Hopper could be utilized as

in System G.

Planning Chart for Model 55, 75, 90, & HMC Systems

"X" = distance from center of bin to where fill system enters the

building.

"H" = height from top of bin pad to where fill system enters the building.

Degree of elevation = Angle at which the system is installed, including

the 30 degree or straight-out Upper Boot.

These layout charts are for planning and reference purposes only. They

illustrate typical system layouts for the FLEX-AUGER Feed Delivery

Systems. Different combination of elbows and straight tube may be re-

quired for your installation, depending on the distance from the bin to

the building and the height at which the auger tubes are to enter the

building. PVC elbows are easily cut to any angle required.

PAY PARTICULAR ATTENTION TO THE MINIMUM DISTANCE FROM

BIN TO BUILDING.

Many installation and operational difficulties can be avoided if the bin

is located farther from the building. If in doubt, it is BETTER TO BE

TOO FAR AWAY THAN TOO CLOSE.

Take special notice of the warnings and safety decals on the equipment

and in this manual.

Always wear protective clothing and protective glasses when working

with the equipment.

Discarded materials, equipment, and boxes may be recycled. Recycle

according to local and national codes.

Unless otherwise specified, the Model 55, 75, 90, & HMC Systems are

installed similarly.

All the systems are available with straight-out or 30 degree upper

boots, except the Model 55. The Model 55 requires the 30 degree upper

boot (the straight-out boot is not available for the Model 55).

Bin Location and Collar Information

For easiest installation and trouble-free operation, locate the feed bin

in a direct line with the FLEX-AUGER System. The layout chart

provides some points of reference for bin placement according to the

height at which the system enters the building.

The bin collar is installed during bulk bin assembly. Chore-Time bins

have a welded collar. Bin Adapter Kits are available to modify existing

bins so that the welded collar can be used. In addition, most other feed

bin manufacturers have a collar available to be used with Chore-Time

FLEX-AUGER Feed Delivery Systems.

Boot Installation

1. Insert the upper boot into the bin collar opening and turn it to line

up with the direction that the auger line will go. The boot must be

as far up into the opening as it will

go. Use the holes in the ring for

drilling guides and drill 11/32" (8.8

mm) holes in the upper rim of the

boot. Attach the boot to the Bin

Collar using the hardware provided.

See Figure 1 for correct use of

hardware to attach the boot.

IMPORTANT: Failure to install the

hardware as shown in Figure 1 may

cause breakage of the red boot

body.

2. Attach the transfer plate to the upper boot. Use truss head bin-seal

bolts installed from the inside of the plate, with flat washers placed

under the nuts.

3. Insert the slide into the transfer plate slot so that it is in its

operating position before bolting the slide shield in place. Remove

the paper backing from the sealing strip before fastening the slide

shield to the transfer plate. Use two 5/16-18x3/4" hex head machine

screws to secure the shield.

4. Bolt the lower boot to the transfer plate using four 5/16-18x3/4" hex

head machine screws.

Auger Tube Installation

The FLEX-AUGER Delivery System includes two 45 degree elbows as

standard equipment. These elbows are used to make the sloping

portion of the auger line at the feed bin, and elsewhere in the system

if necessary. If additional elbows are required, they should be ordered

separately. Figure 2 shows how the elbow can be cut into shorter

sections.

1. Determine where the entrance hole for the auger tube must be

located on the building and cut it.

2. Cut the elbow used where the auger enters the building (if

necessary). Slide the seal ring and neoprene seal over the straight

end of the elbow and place it in the hole cut in the building, with the

belled end outside the building. See Figure 3.

3. Model 75, 90, & HMC: Slide the belled end of the elbow or auger

tube over the outlet end of the boot. A clamp is provided to secure

the elbow or auger tube to the boot.

Model 55: Install the Model 55 Stub Tube over the outlet end of the

boot. A clamp is provided to secure the Stub Tube to the boot.

Slide the belled end of the first elbow or auger tube over the stub

tube.

Figure 2. PVC Elbow Cutting Guidelines. (Side View)

15 Degree Elbow......... 16.5" or 419 mm

22.5 Degree Elbow...... 24.75" or 628 mm

30 Degree Elbow......... 33" or 838 mm

These dimensions are measured along

the long, outside curve of the elbow.

They do not include the belled end of

the elbow in the measurement.

FLEX-AUGER Installation & Operator’s Manual •

Page 17

4. Place the end of a straight section of tube inside the belled end

of the elbow in the building. Hold the straight section of auger

tube so that it touches the elbow on the boot. Mark the spot

where the tube aligns with the "boot" elbow and cut the elbow at

that point.

5. Place the belled end of the auger tube over the end of the elbow

just cut, and hold the tube against the top elbow. Mark and cut

the straight auger tube so that it will fit between the two elbows.

Remember to cut the auger tube long enough to fit inside the

belled end of the elbow in the building. Figure 4 shows the di-

rection the auger is to run in relation to the belled end of the

tube. NOTE: In some installations it may be possible to eliminate

the elbow on the boot, using only a straight auger tube and one

elbow where the tube enters the building.

6. Dry-fit all parts. When satisfied that elbows and tubes fit togeth-

er smoothly, glue with PVC cement according to the instructions

on page 62.

7. ALL TUBE JOINTS EXPOSED TO MOISTURE AND WEATHER

Horizontal elbows need to be supported in at least two places. Chain,

screw hooks, and “S” hooks are supplied as a suspension kit for sup-

porting the equipment. Keep the line as level and straight as possible.

If Drop Feeders, Extension Hoppers, Outlet Drops with long angled

Drop Tubes, or other loads are imposed on the system, extra support

must be added at that point.

Power Units require extra support to resist the twisting encountered

when the motor starts and stops. Use all of the "ears" on the gearhead

as well as the suspension point provided on the 6500 Control Unit Box

to support the Power Unit. See Figure 14 on page 24.

Adequate chain and “S” hooks are provided with each system to prop-

erly support it.

Other means of supporting the system are permissible as long as the

system receives the correct support and the auger tube is not dented

or flattened. Alternative support systems must allow for expansion and

contraction of the auger tubes.

When the auger tube passes through a side wall or partition, especially

where it enters the building, the opening should be made large enough

so the auger tube can be supported without resting on the wall. If the

auger tube rests on the wall or partition, the auger tube may flatten out

or become kinked--causing excessive wear. See Figure 6.

Figure 5. (End View)

8. If there is more than 15 feet (4.5 meters) of auger tube between

the boot and the building, provide additional support for the

tubes so that the boot does not have to carry the weight of the

auger. Extra support can be achieved with cables or chains fas-

tened to the bin legs and auger tube.

9. Install the remaining tubes in the system AFTER the outlet holes

have been located and cut. The auger tubes should be cemented

using PVC cement supplied. NOTE: The tubes can be joined by

cutting off the belled ends and fastening tubes together with

tube connectors if there is some reason why permanent installa-

tion is not desired. (Tube Connectors are not standard equip-

ment and must be ordered separately for this type of

installation).

Supporting the System--Inside the building

Support the auger tubing with chain and "S" hooks every 5 feet (1.5

m). Steel tube systems require support every 10 feet (3 m).

The sys-

tem should be restrained from swinging by using chain and "S"

hooks to brace the auger tube, every 20 feet (6 m), as shown in Fig-

ure 5.

Supporting the System--Outside the Building

Some systems require additional support to avoid sagging auger tubes.

This support must be adequate to support the weight of the auger tubes

filled with feed. Special attention should be given to avoid excessive

pressure from the auger being transferred to boot. Chain or cable sus-

pended from the bin or building will not provide adequate support for

these systems.

Some common systems are shown in Figures 7, 8, and 9, with the rec-

ommended supports.

Note: Supports must be designed to prevent (weight) loads from being

transferred back onto the boot.

Outlet Drops Installation

Cut the outlet hole in the auger tube. A sabre saw or hacksaw is handy

for making the cuts when total feed dropout is desired. See the diagram

and related chart for dimensions of outlet holes. IMPORTANT: THESE

HOLE SIZES DO NOT APPLY FOR DROP FEEDER INSTALLATIONS.

Refer to the Drop Feeder Manual (shipped with the Drop Feeder Control

Unit) for proper Drop Feeder holes sizes.

The outlet hole may be either square or round, as shown in Figure 10.

Refer to Figure 11 for Outlet Drop assembly procedure.

1. Wrap the rotary slide around the auger tube.

POSITION SLIDES IN SAME DIRECTION FOR ALL DROPS SO

THAT THE SLIDES WILL ALL OPERATE THE SAME WHEN ROPES

ARE PULLED.

2. Thread the rope through the ends of the rotary slide.

3. Tie the ends of the rotary slide together so that the ends of the rope

are the same length.

4. Open rope guide holes molded into the drop halves with a 3/16" (4.8

mm) drill bit.

5. Thread the rope ends through the guide holes in the drop halves.

6. Position drop halves over the rotary slide and fasten the two halves

together using the hardware supplied.

7. Test the operation of the rotary slide by pulling on the ends of the

rope. Be sure the outlet drop is centered over the outlet hole, then

move the rotary slide to the open position (check by looking up

through the drop opening) and mark the short end of the rope where

it goes through the guide hole.

Tie a knot in the rope at the marked spot to act as a stop for the

rotary slide.

8. Install green and red indicator balls on the ends of the rope. Tie

knots in the rope to hold the balls in place. Use the green ball on

the rope to open the outlet drop. Use the red ball on the rope to

close the drop. The ball will show at a glance if the slide is open.

9. Use a small amount of PVC cement on the auger tube around the

drop to prevent the drop from shifting.

5163 Outlet Drop Installation

The 5163 Outlet Drop is available for use with steel tube Model 75

FLEX-AUGER Systems only. Place the outlet drop over the hole in the

tube and use hardware provided to fasten it to the tube. Figure 12

4. Place a tube clamp on the tube anchor and connect the control

unit/power unit assembly to the end of the FLEX-AUGER tube.

Note: The switch in the control unit is a safety backup switch in case

the hopper level switch or drop tube switch fails to shut off the

system. DO NOT use the safety switch to control the FLEX-AU-

GER System. This will cause feed to bridge in the control.

5. Support the Power Unit and Control Unit securely. Points are pro-

vided at the gear head and the tube anchor for suspending the

equipment with chain and “S” hooks supplied with the delivery sys-

tem. See Figure 14. NOTE: Other ways of supporting the delivery

system can be used where it is practical, as long as the supports do

not let the equipment sag or do not make flat spots in the auger

tubes.

Note: The motor should be fastened to keep it from twisting. "S" hooks

and chain can be used to prevent the motor from shifting.

6. Install the driver assembly on the power unit shaft. Start the socket

Belt Drive Control Unit Installation

The Belt Drive Control Unit installation is much the same as the direct

drive unit. Mount the Belt Drive Adapter and Motor to the control unit,

then proceed with installation to the auger tube as described in this

manual. Page 48 can be used as an assembly guide for the Belt Drive

Control Unit. Figure 15 shows a Belt Drive Control Unit suspended.

Auger Installation

Use extreme caution when working with the auger. The auger is under

tension and may spring causing injury. Always wear protective clothing

and protective glasses when working with the auger.

Use extreme caution when pushing the auger into the auger tubes. Keep

your hands away from the end of the auger tube to avoid injury.

Handle the FLEX-AUGER carefully. Dropping the rolls of auger may

cause the auger to kink. Do not install an auger that has a sharp kink

in it. The kink will cause the auger to wear a hole in the tube at that

spot. If the kink cannot be straightened with pliers, the kink must be

cut out and the auger brazed back together. Refer to the "Auger

Brazing" section in this manual for the correct brazing procedure.

1. Beginning at the boot, push the auger into the auger tube through

the rear of the boot until the auger reaches the control unit end of

the line.

Use extreme caution when pushing the auger into the auger tubes. Keep

your hands away from the end of the auger tube to avoid injury.

4. Attach the drop tube and install the slide cover on the control unit.

5. Pull on the loose end of the auger at the boot once or twice until it

begins to stretch, then release it slowly. This will bring the auger to

its natural length.

IMPORTANT: Stretch the auger 2 inches (50 mm) for every 50 feet

(15.2 m) of length. Example: For a 150 ft. (45 m) system the auger

should be cut 6 inches (150 mm) shorter than its natural length.

Measure the amount of stretch from the rear edge of the boot and cut

the auger at that point.

Note: For ease of cutting, measure and mark the auger at the point

where it is to be cut. Then, pull the auger an additional 6-8" (150-200

mm) and use locking pliers to clamp the auger while you cut it.

6. Figure 18 shows the proper assembly of the Model 55 boot

components. Insert the Auger over the Anchor and through the

Auger Clamp until Auger touches washer. Torque Set Screw into

Auger Clamp 10-12 ft-lbs. Over tightening the Set Screw may cause

damage to the Auger Clamp.

Figure 19 shows the proper assembly of the Model 75 boot

components. Insert the anchor into the auger until the auger

touches the anchor flange. The auger must be threaded onto the

Boot Anchor Assembly, through the clamp pin. Use a 5/16”

open-end wrench to tighten the clamp pin setscrew on the auger.

Auger Brazing

If the auger needs to be spliced or lengthened, locate the brazed joint

closer to the power unit to minimize feed flow restriction in the line.

To align the auger for brazing, lay it in angle iron and clamp securely.

Rotate the auger to allow both the inside and outside edges of the au-

gers to be brazed.

Butt the ends of the auger against each other. DO NOT SCREW ONE

AUGER INSIDE THE OTHER--This restricts the feed flow.

Figure 23 and the associated chart specify how far to lap the augers.

A bronze, flux-coated rod is recommended. The joint should be well

filled and smooth so that it does not wear against the tube. Allow the

joint to air cool.

File the auger edges, as shown in Figure 24, to avoid damage to the

auger tubes. Also, file off any brazing that extended beyond the outside

radius of the auger flightings.

Restrictor Adjustment

Baffled Boots do not use Restrictors and are designed to carry the rat-

ed capacity.

The Model 90 Single 30° Boot and the HMC Boots (except for the Twin

Straight-Through Tandem Systems) have Restrictors that may be ad-

justed for increased delivery capacities.

DO NOT ADJUST THE RESTRICTOR UNTIL THE SYSTEM HAS BEEN

IN OPERATION AND THE SYSTEM IS BROKEN IN.

THE MODEL 55 RESTRICTOR IS NOT ADJUSTABLE.

Note: Feed delivery capacities are based on 40 lbs/ ft.3 (640 kg/m3)

feed density. Systems using lighter weight feeds may not be able

to achieve the maximum capacities listed.

Note: Always refer to the motor amperage nameplate when increasing

the feed flow capacity. Exceeding the nameplate amperage may

result in nuisance motor overload tripping and/or damage to the

system.

1. Loosen the tube clamp on the back of the Lower Boot to remove the

Anchor and Bearing Assembly from the boot.

2. Use extreme caution when working with the auger under tension.

Springing auger can cause personal injury.

Pull enough of the auger out of the auger tube to allow the Restric-

tor Tube to be cut.

Use locking pliers to hold the auger outside the boot.

3. Use a hacksaw to cut 1" (25 mm) at a time off the end of the Re-

strictor Tube to increase feed flow. See Figure 25.

4. CAREFULLY remove the locking pliers while holding on to the An-

chor and Bearing Assembly and auger securely.

5. CAREFULLY allow auger to draw the Anchor and Bearing Assembly

back into the Lower Boot. DO NOT ALLOW THE BEARING TO BE

SLAMMED BACK INTO THE BOOT.

Key Description

Feed Level Control Installation

The Hopper Level Control (or Drop Tube Switch) is installed in the feed

hopper (or in the drop tube over the feeder) at the power unit end of

the line. This feed flow control switch stops the FLEX-AUGER System

when the last feeder is full. Install the hopper level control or drop tube

switch according to instructions shipped with the unit.

The wiring diagram for each type of delivery system shows how the

hopper level control (drop tube switch is the same) must be wired into

the control unit.

For Model 90 & HMC FLEX-AUGER systems, the belled end of the au-

ger tube fits directly over the outlet end the Straight-Out Boot. The

straight end of the Auger Tube connects to the incoming end of the

Straight-Thru Boot, using a Tube Connector. See Figure 27.

For Model 75 FLEX-AUGER (PVC) systems, slide the belled end of the

Model 75 Auger Tube over the outlet of the Straight-Out Boot. The

straight end of the Auger Tube connects to the incoming end of the

Straight-Thru Boot, using a Tube Insert and Tube Connector.

For Model 75 FLEX-AUGER (Steel) systems, slide the straight end of

the Model 75 Auger Tube into the outlet end of the Straight-Out Boot.

The belled end of the Auger Tube should be slid over the inlet end of

the Straight-Thru Boot. See Figure 27.

Remember to caulk all tube joints exposed to weather or moisture.

Straight-Through Tandem Installation

(Model 75, 90, & HMC systems ONLY)

The Straight-Through Tandem Boots allow one or two augers to remove

feed from two separate feed bins. Feed should only be drawn from one

bin at a time.

Solid Cannonballs are used in conjunction with the Boot Baffles.

1. Install boots on both feed bins. Be sure the outlets and inlets on the

boots are in line and arrow tape is pointed in direction of feed flow.

Operating Recommendations for the

Model 55, 75, 90, & HMC FLEX-AUGER

1. During initial start-up, the boot slide should be only partially open

to prevent the full length of auger from being charged with feed.

After that, the boot slide must be fully open for delivery

system operation.

2. Do not permit the FLEX-AUGER system to operate empty. Use

a time clock or Auger Timer with the system whenever possible.

This reduces short cycling by operating on a preset schedule

instead of on demand. It also prevents excessive running of the

system if the bin becomes empty. If the optional boot switch is

used, the fill system will shut down when the bin becomes empty.

3. Program the time clock to fill feeders often so the FLEX-AUGER

System does not have to run a long period of time to get feeders

filled. Poultry feeders supplied by the FLEX-AUGER System

should be operated by a time clock so feeders start at the same

time. This gives the FLEX-AUGER System a better chance to

keep up with them. Note: The hopper level control must be

positioned low in the last feeder hopper.

4. The red light on the control unit will light if feed has packed

inside. If this happens, remove feed from the drop tube and tap

the side of the power unit to clear the safety switch. Keep the

hopper level control in adjustment and positioned straight up and

down so the paddle swings freely. The safety switch does not

take the place of the hopper level control.

5. If the FLEX-AUGER System must be used to convey

high-moisture feed, empty the auger line completely after each

running to prevent the feed from setting up in the tubes.

6. On Baffled Boots, the flow rates are predetermined with factory

installed Baffles. The Baffles are non-adjustable.

On Non-Baffled Boots, the restrictor on the boot anchor regulates

the amount of feed flowing into the auger. Start a new system with

the restrictor installed as shipped

Allow the system to polish out before adjusting the feed flow. If

more feed flow is desirable, the restrictor may be shortened.

Refer to the section “Restrictor Adjustment” on pages 30 - 31.

7. When feeding with the Straight-Through Tandem System, open

the slide on only one bin at a time!

FLEX-AUGER Installation & Operator’s Manual •

Page 40

Start-Up Procedure for New Systems

DO NOT RUN FEED THROUGH A NEW SYSTEM UNTIL AFTER

THIS PROCEDURE HAS BEEN FOLLOWED OR THE AUGER

WILL PLUG AND BIND.

1. Close the slide on the FLEX-AUGER boot.

2. Operate the system empty for one minute.

3. Open the slide on the FLEX-AUGER boot no more than 1 inch

(25 mm) to allow some feed into the boot.

4. Operate the system with the slide in this position until feed has

been conveyed into the building at least 5 minutes.

This removes the manufacturing grease and oil from the auger

and tubes. If this grease and oil is not removed, the feed may ball

up causing the auger to plug and bind.

5. Now the slide can be fully opened and the system operated

normally.

and overheats). Check line voltage at the motor;

use adequate size wire in cir-

cuits.

Foreign object in the auger

(motor runs, stalls, then auger

spins in reverse).

Check auger line, pull auger to

remove objects.

Motor wired in reverse (motor

runs, stalls, no feed conveyed). Disconnect power and change

wire connections (direct drive

power unit shaft at rear of motor

turns clockwise).

Maintenance of the FLEX-AUGER System

The FLEX-AUGER Feed Delivery System requires minimum

maintenance. However, a routine periodic inspection of the

equipment will prevent unnecessary problems.

Maintenance should be done by a qualified technician.

ALWAYS DISCONNECT POWER TO THE SYSTEM WHEN

SERVICING OR MAINTAINING THE EQUIPMENT. FAILURE TO

DISCONNECT POWER MAY CAUSE INJURY OR DEATH.

1. Periodically check and tighten the delivery system hardware.

2. Grease boot bearings on grease fittings regularly, using an auto-

motive or industrial type grease.

3. Keep the FLEX-AUGER tubes level. Adjust if necessary. Wear in-

creases at the points where tubes sag.

4. Replace the Plastic Shipping Plug in the power unit gear head

with the Vented Plug during installation of the Power Unit.

5. Check the oil level in the gear heads at installation and every 6

months. The Pipe Plug, on the side of the gear head, indicates

proper oil level. Add SAE 40W oil when necessary.

The oil in the gear heads should be replaced every 12 months

with new SAE 40W oil.

A. Remove the bottom Pipe Plug to drain the oil. Discard used

oil in accordance with local and national codes.

B. Wipe any debris off the magnet on the bottom Pipe Plug and

reinstall. Remove the side Pipe Plug and (top) Vent Plug.

C. Set the power unit in the horizontal position.

D. 2-Stage Gear Heads: Add approximately 9 oz. (266 ml) of

SAE 40W oil through top hole. This should be just enough oil

to reach the side Pipe Plug.

3-Stage Gear Heads (3261-9, 3261-12, 3261-14): Add

approximately 13 oz. (384 ml) of SAE 40W oil through top

hole. This should be just enough oil to reach the side Pipe

Plug.

E. Install the side Pipe Plug and (top) Vent Plug.

6. Extension Hopper Switch Adjustment Procedure:

A. CAUTION: DISCONNECT POWER.

B. Make sure no feed is against the Paddle.

C. Turn adjusting nut clockwise until switch clicks.

D. Turn adjusting nut counterclockwise until switch clicks.

E. Turn adjusting nut counterclockwise one half turn.

FLEX-AUGER Installation & Operator’s Manual •

7. If the system is not to be used for an extended period of time,

remove all the feed from the auger lines.

Disconnect power to the system to prevent accidentally starting

the system.

8. If the system must be disassembled, extreme caution must be

used to prevent injury from springing auger.

A. Disconnect power to the

entire system.

B. Pull the Anchor and

Bearing Assembly and

approx. 18” (45 cm) of

auger out of the boot.

C. Place a clamp or locking

pliers on the auger to

prevent it from spring-

ing back into the auger

tubes.

D. Remove Anchor and Bearing Assembly.

E. Carefully release the clamp securing the auger.

CAUTION: Stand clear...the auger will spring back into

the tubes.

F. Remove the remaining system components in the opposite

order they were installed, according to this manual.

9. Replacing the battery in the Agri-Timer:

A. Disconnect electrical service at the breaker.

B. Remove the (2) screws and the face of the timer.

C Replace the existing batteries with new batteries.

D. Use existing wire ties to secure the new batteries in place.

E. Reinstall the face of the timer and secure using (2) screws

previously removed.

F. Reconnect electrical service to the system.

10. Proximity Switch Adjustment Procedures:

The Proximity Switch includes an adjustable delay. The delay

may be set from 1 second to 10 minutes.

A. Use a small screw driver provided to turn the Delay Adjust-

ment Screw (see figure on page 62). Turn the screw counter

clockwise until the light stays on. Turn the screw clockwise

one complete revolution. This sets the delay to 1 second.

B. To increase the delay, turn the Delay Adjustment Screw

clockwise.

Watch the indicator light; quick flashes = shorter time delay,

slow flashes = longer time delay.

The Proximity Switch is shipped with the sensitivity preset at the

factory. This setting is adequate for most feed types and

conditions. However if the sensitivity does need to be adjusted,

carefully follow these instructions:

Cementing the PVC Auger Tube

The auger tubes and elbows for the FLEX-AUGER systems are made of special-

ly formulated PVC tubing. Use the PVC solvent cement to make strong, reliable

bonds.

FOLLOW DIRECTIONS ON THE CAN FOR SAFE HANDLING OF CEMENT.

1. Be sure tube is cut off squarely. Remove burrs from outside and inside the

end of the tube.

2. Dry fit all parts. Tube should fit inside belled end of next tube to full depth

without excess force.

3. Clean surfaces to be joined. SURFACES MUST BE FREE OF DIRT OR

GREASE!

4. Apply a generous coat of cement to both the inside of the belled end and

outside of the other tube. Be sure cement covers all of the joint area so

there are no bare spots.

5. Quickly join the tubes, giving them a twisting motion to bring them into

alignment as they are joined.

6. Keep pressure on the joint until the PVC cement sets up.

A. Allow power to be supplied to the switch for at least 15 minutes

to properly warm the sensor. Chore-Time recommends wiring

the proximity switch to have a constant 220 V. supply. See the

wiring diagrams provided with the Proximity Switch.

B. Set the Proximity Switch time delay to 1 second as specified in

the instructions on page 61.

C. Use a small screw driver to remove the caulk concealing the

Sensitivity Adjustment Screw (see figure below).

D. IMPORTANT: A Proximity Switch may be used in a feed bin boot

to shut the fill system down when it no longer senses feed.

A Proximity Switch may also be used as a feed level switch at

the control end of the line. In this application the switch is used

to shut the system down when it senses feed.

Before adjusting the Proximity Switch, carefully consider how

you want the switch to react when it senses feed. For addition

information, see the instructions shipped with the Proximity

Switch.

Greater switch sensitivity is achieved by turning the Sensitivity

Adjustment Screw clockwise.

Less switch sensitivity is achieved by turning the Sensitivity

Adjustment Screw counterclockwise.

Note the screw orientation before beginning adjustment. Adjust

the Sensitivity Adjustment Screw 1/4 turn, test switch, continue

adjusting as required.

TO DETERMINE THE RUNNING TIME PER DAY-Multiply the number of animals by the

feed consumption/head figures from the charts to get Total Feed Consumption.

-Divide Total Feed Consumption by the stated delivery rate of the FLEX-AUGER Feed

Delivery System to get running time per day in minutes. Divide this by 60 to get running

time per day in hours.
