GENERAL SAFETY RULES
WARNING!
READ AND UNDERSTAND ALL INSTRUCTIONS
Failure to follow all instructions listed below may result in
electric shock, fire, and/or serious injury.
SAVE THESE INSTRUCTIONS
Work Area
Keep your work area clean and well lit. 1. Cluttered benches and dark areas invite accidents.
Do not operate power tools in explosive atmospheres, such as in the presence 2.
of flammable liquids, gases, or dust. Power tools create sparks which may ignite
the dust or fumes.
Keep bystanders, children, and visitors away while operating a power tool. 3. Dis-
tractions can cause you to lose control. Protect others in the work area from debris
such as chips and sparks. Provide barriers or shields as needed.

Electrical Safety
Avoid body contact with grounded surfaces such as pipes, radiators, ranges, and 1.
refrigerators. There is an increased risk of electric shock if your body is grounded.
Do not expose power tools to rain or wet conditions. 2. Water entering a power tool
will increase the risk of electric shock.
Grounded tools must be plugged into an outlet properly installed and grounded 3.
in accordance with all codes and ordinances. Never remove the grounding prong
or modify the plug in any way. Do not use any adapter plugs. Check with a quali-
fied electrician if you are in doubt as to whether the outlet is properly grounded.
If the tools should electrically malfunction or break down, grounding provides a low
resistance path to carry electricity away from the user.
Double insulated tools are equipped with a polarized plug (one blade is wider 4.
than the other). This plug will fit in a polarized outlet only one way. If the plug
does not fit fully in the outlet, reverse the plug. If it still does not fit, contact a
qualified electrician to install a polarized outlet. Do not change the plug in any
way. Double insulation eliminates the need for the three wire grounded power cord
and grounded power supply system.
Do not abuse the Power Cord. Never use the Power Cord to carry the tools or pull 5.
the Plug from an outlet. Keep the Power Cord away from heat, oil, sharp edges,
or moving parts. Replace damaged Power Cords immediately. Damaged Power
Cords increase the risk of electric shock.
When operating a power tool outside, use an outdoor extension cord marked 6.
“W-A” or “W”. These extension cords are rated for outdoor use, and reduce the risk
of electric shock.
Personal Safety
Stay alert. Watch what you are doing, and use common sense when operating a 1.
power tool. Do not use a power tool while tired or under the influence of drugs,
alcohol, or medication. A moment of inattention while operating power tools may
result in serious personal injury.
Dress properly. Do not wear loose clothing or jewelry. Contain long hair. Keep 2.
your hair, clothing, and gloves away from moving parts. Loose clothes, jewelry, or
long hair can be caught in moving parts.
Avoid accidental starting. Be sure the Power Switch is off before plugging in. 3.
Carrying power tools with your finger on the Power Switch, or plugging in power tools
with the Power Switch on, invites accidents.
Remove adjusting keys or wrenches before turning the power tool on. 4. A wrench or
a key that is left attached to a rotating part of the power tool may result in personal injury.
Do not overreach. Keep proper footing and balance at all times. 5. Proper footing
and balance enables better control of the power tool in unexpected situations.
Page 4SKU 93188 For technical questions, please call 1-800-444-3353
Use safety equipment. Always wear eye protection. 6. Dust mask, nonskid safety
shoes, hard hat, or hearing protection must be used for appropriate conditions.
Tool Use and Care
Do not force the tool. Use the correct tool for your application. 1. The correct tool
will do the job better and safer at the rate for which it is designed.
Do not use the power tool if the Power Switch does not turn it on or off. 2. Any tool
that cannot be controlled with the Power Switch is dangerous and must be replaced.
Disconnect the Power Cord Plug from the power source before making any adjust-3.
ments, changing accessories, or storing the tool. Such preventive safety measures
reduce the risk of starting the tool accidentally.
Store idle tools out of reach of children and other untrained persons. 4. Tools are
dangerous in the hands of untrained users.
Check for misalignment or binding of moving parts, breakage of parts, and any 5.
other condition that may affect the tool’s operation. If damaged, have the tool
serviced before using. Many accidents are caused by poorly maintained tools.
Use only accessories that are recommended by the manufacturer for your model. 6.
Accessories that may be suitable for one tool may become hazardous when used on
another tool.
Service
Tool service must be performed only by qualified repair personnel. 1. Service or
maintenance performed by unqualified personnel could result in a risk of injury.
When servicing a tool, use only identical replacement parts. Follow instructions 2.
in the “Inspection, Maintenance, And Cleaning” section of this manual. Use of
unauthorized parts or failure to follow maintenance instructions may create a risk of
electric shock or injury.

power cord or plug is damaged. If damaged, have it repaired by a service facil-
ity before use. If the plug will not fit the outlet, have a proper outlet installed by
a qualified electrician.
GROUNDED TOOLS: TOOLS WITH THREE PRONG PLUGS
Tools marked with “Grounding Required” have a three wire cord and three prong ground-1.
ing plug. The plug must be connected to a properly grounded outlet. If the tool should
electrically malfunction or break down, grounding provides a low resistance path to carry
electricity away from the user, reducing the risk of electric shock. (See Figure A.)
The grounding prong in the plug is connected through the green wire inside the cord 2.
to the grounding system in the tool. The green wire in the cord must be the only wire
connected to the tool’s grounding system and must never be attached to an electrically
“live” terminal. (See Figure A.)
Your tool must be plugged into an appropriate outlet, properly installed and grounded in 3.
accordance with all codes and ordinances. The plug and outlet should look like those
in the following illustration. (See Figure A.)
FIGURE A FIGURE B
DOUBLE INSULATED TOOLS: TOOLS WITH TWO PRONG PLUGS
Tools marked “Double Insulated” do not require grounding. They have a special double 1.

ceding illustration. (See Figure B.)
Ground Fault Circuit Interrupter (GFCI)
A Ground Fault Circuit Interrupter (GFCI) is manufactured within the Power Cord (15),
about midway, due to the risk of electrical shock when operating the Drain Cleaner, and its
proximity to water and ground. The GFCI provides additional protection from the risk of elec-
trical shock.
Make sure that the Motor Direction Switch is in the Off position before plugging in the 1.
Drain Cleaner.
Plug the GFCI Power Plug into a grounded, 120 VAC electrical outlet.2.
Press the TEST button, then press the RESET button. The GFCI indicator should show 3.
Red in the window.
If the indicator is not red, try plugging the Power Cord into a different electrical outlet
and repeat the steps. If the same results occur, have the Power Cord inspected by a
licensed electrician. Repair or replacement must be completed by a licensed electri-
cian.
Note: The Power Cord is not GFCI protected from the GFCI unit to the 3-prong plug in the
electrical outlet.
EXTENSION CORDS
Grounded1. tools require a three wire extension cord. Double Insulated tools can use
either a two or three wire extension cord.
As the distance from the supply outlet increases, you must use a heavier gauge exten-2.
sion cord. Using extension cords with inadequately sized wire causes a serious drop
in voltage, resulting in loss of power and possible tool damage.
(See Figure C, next page.)
The smaller the gauge number of the wire, the greater the capacity of the cord. For 3.
example, a 14 gauge cord can carry a higher current than a 16 gauge cord.
(See Figure C.)
When using more than one extension cord to make up the total length, make sure each 4.
cord contains at least the minimum wire size required. (See Figure C.)

OPERATING INSTRUCTIONS
The following sections describe the operational components and controls of the Drain
Cleaner, as well as its operation and application.
Operational Components and Controls
Warning: Do not allow your hands, clothing or any other object to become caught
between the belt and the drum. Serious personal injury could result.
The main operational components of the Drain Cleaner tool are the Motor (7), with its 1.
Motor Direction Switch (5), Foot Switch (14) and the Cable Feed Unit (44a) with its
direction controller.
The 2. Motor (7) is connected to the Drum (38a) using a Drive Belt (2). When turned on,
the Motor turns the Drum, which causes the Spring Cable (39a) to rotate. Rotation of
the Spring Cable helps it to move through bends or turns in the drain line, and also to
drill through soft clogs, or entangle harder clogs for removal. (See photo below, left.)
The 3. Motor Direction Switch (5) has NORMAL, UNBIND and OFF settings. NORMAL
will set the Spring Cable to rotate clockwise (viewed from machine rear), causing it to
bore into or entangle any obstruction. UNBIND will cause the Spring Cable to rotate
counterclockwise (viewed from machine rear), causing it to unwind from any obstruc-
tion. (See photo below, right.)
Motor (7), Drum (38a) and Drive Belt (2). Motor Direction Switch (5)
The Motor is controlled by a 4. Foot Switch (14). Whenever the Motor Direction Switch
(5) is in the NORMAL or UNBIND position, stepping on the Foot Switch (14) will cause
the motor to run and the Drum (38a) to turn. NOTE: The Foot Switch is in a rubber boot
to make it water-resistant. (See photo on page 10, top-left.)
The rotating Drum causes the Spring Cable (39a) to rotate along its axis like a drill. 5.
The Direction Lever (44-16) on the Cable Feed Unit (44a) controls the motion of the
Spring Cable (39a) forward into the drain or back into the Drum (38a). The feed tension
is control by the Star Knob (44-13). See photo on page 10, top-right. The Star Knob
(44-13) must be loosened before changing the position of the Direction Lever (44-16),
and then retightened after the adjustment.

CAUTION: DO NOT USE THIS DRAIN CLEANER ON DRAIN LINES SMALLER THAN
TWO INCHES. DAMAGE MAY OCCUR TO EQUIPMENT OR PIPES.
Place the Drain Cleaner within two feet of the drain pipe inlet.1.
Pull Cable (39a) from the Drum (38a) and begin feeding it into the drain pipe inlet as 2.
far as it will go manually.
Verify that the Motor Direction Switch (5) is in the Off position, then plug the Power 3.
Cord (15) into an electrical outlet. Press the Reset button on the GFCI.
Loosen the Star Knob ( 44-13) by turning it counterclockwise until it is no longer 4.
pressing against the cable. See photo on page 10.
Pull the Direction Lever (44-16) up (FORWARD) to feed Cable out of the Drum. 5.
Pushing the Direction Lever down (REVERSE) will retract the Cable back into the
Drum. When the lever is in the middle (NEUTRAL) position, the Cable will spin in
place.
Move the Motor Direction Switch (5) to the Forward position. 6. Caution: 6. Do not
force the Cable. Let the cutter do the work.
Turn (clockwise) the Star Knob (44-13), at the top of the Cable Feed Unit, until the 7.
feed roller touches the Cable, then one quarter additional turn. Do not overtighten,
excessive cable wear will occur. See photo on page 10.
Wearing a leather glove, place your hand on the Guide Tube or Cable, press the Foot 8.
Switch (14) to start the forward Cable movement. Feed the Cable into the drain pipe
inlet with a firm and even pressure against any resistance. Adjust the feeding rate to
the resistance met. Do not force the Cable. Let the cutter do the work. Run hot wa-
ter down the drain pipe during and after the removal of the stoppage to wash away
debris.
After the drain pipe has been opened, return the cable to the Drum. 9.
To do that: Place the Direction Lever (44-16) in the UNBIND direction. Press the Motor
Direction Switch (5) to the NORMAL position. Press on the Foot Switch (14) to recoil
Cable. When the cutter head is near the drain pipe inlet, release Foot Switch to stop
Drum rotation. NOTE: If necessary, replace the cutter tool with the U-Cutter or Side
Cutter, and reenter the drain pipe to clean the pipe walls.
Caution: Avoid damage to Cable or cutting tool. Do not use the Motor Direction Switch 10.
(5) in the Reverse position to pull the Cable out of the drain pipe. Always leave the
Switch (5) in the NORMAL position, whether feeding the Cable into the drain pipe, or
pulling it out. Use Reverse position only to release the Cable if it should become caught
in the drain pipe line, and only for a few seconds.
When the job is complete, unplug the Power Cord from the electrical outlet and coil it. 11.
Store the Drain Cleaner and cutter tools in clean and dry location.

steady pressure to Cable. Keep in mind that this will reverse auto
feed operation as well. Do for only a few seconds to pass bend.
More time could cause tangling or kinks in the Drum. If problem
persists, Cable is too large for pipe. Switch to a drain cleaner with
a smaller cable
When Cable reach-
es clog in drain pipe
Do not force Cable through stoppage. Press Direction Lever to
neutral position. Allow Cable to progress forward slowly, chew-
ing stoppage. Slow forward move-ment reduces stress on Cable,
while cleaning better. Try back and forth Cable movement, us-
ing the Direction Lever (44-16).9. After the drain pipe has been
opened, return the cable to the Drum. To do that: Place the Direc-
tion Lever (44-16)

INSPECTION, MAINTENANCE, AND CLEANING
WARNING! Make sure the Power Switch of the Drain Cleaner is in its “OFF”
position and that the tool is unplugged from its electrical outlet before performing any
inspection, maintenance, or cleaning procedures.
General
Before each use,1. inspect the general condition of the Drain Cleaner. Check for loose
screws, misalignment or binding of moving parts, cracked or broken parts, damaged
electrical wiring, and any other condition that may affect its safe operation. If abnormal
noise or vibration occurs, have the problem corrected before further use. Do not use
damaged equipment.
Periodically recheck all nuts, bolts, and screws for tightness.2.
After each use, clean the Drain Cleaner components with a wet, clean cloth. Wipe dry 3.
when clean.
Always keep Cable (39a) well oiled by pouring oil directly into the Drum (38a). Then 4.
push the Motor Direction Switch (5) to the NORMAL position. The Drum will rotate. Do
this until the entire Cable is lubricated. Lubricate all other moving parts adequately to
protect against corrosion, sand, grit, and other abrasive material.
Store unit in a clean and dry location. Cover unit with a cloth cover.5.
Auto Feed Maintenance
Keep the auto feed mechanism free of excessive soil and grit. It is recommended that
it be flushed with fresh water, followed by a light oiling of the moving parts. No disassembly
is normally required. Failure to feed during operation can usually be traced to the build up of
soil and grit. Over time, dirt can harden enough to stop roller rotation. Flushing with water,
followed by liberal oiling can usually restore function. If disassembly is required, proceed
as follows:
Remove the two bolts that hold the Front Cap (44-19) and internal roller to the Case 1.
(44-11).

Guide Wheel Replacement
Guide Wheels (44-9) due to excessive use may be damaged to a point of failure and
need replacement. Replace all three Guide Wheels at the same time.
Tangled Cable
If the Cable loops over itself in the Drum, it will not feed properly. With the motor stopped
and cord unplugged, remove and reload the Cable by hand to restore proper functioning. If
the Cable kinks, it is evidence of abuse and results from the use of too much pressure when
drain cleaning, or use of the wrong size Cable for the drain pipe being cleaned. Do not force
the Cable during use, let the cutter tool do the work.
Removing a Stuck Cable in the Drain Pipe
If the cable gets caught in the drain pipe move the Motor Direction Switch (5) to the Off 1.
position. Then, once the drum has stopped turning, move the Motor Direction Switch
(5) to the Reverse position to free the Cable.
If using the Power Cable Feed, putting the Motor in reverse will cause the feed Direc-2.

tion.
Caution: Running the Motor in reverse for more than a few seconds at a time can
cause the Cable to tangle in the Drum.
