Additional Safety Instructions for Bandsaws
9. THIS MACHINE IS NOT DESIGNED TO
CUT METAL or other material except
wood.
10. DO NOT MANUALLY STOP OR SLOW
BLADE after turning the saw off. Allow
it to come to a complete stop before you
leave it unattended.
11. ALL INSPECTIONS, ADJUSTMENTS,
AND MAINTENANCE MUST BE DONE
WITH THE POWER OFF and the circuit
breaker shut off. Wait for all moving parts
to come to a complete stop.
12. HABITS – GOOD AND BAD – ARE
HARD TO BREAK. Develop good habits
in your shop and safety will become sec-
ond-nature to you.
13. IF AT ANY TIME YOU ARE EXPERIENC-
ING DIFFICULTIES PERFORMING THE
INTENDED OPERATION, STOP USING
THE BANDSAW! Then contact our ser-
vice department or ask a qualified expert
how the operation should be performed.
14. MAKE SURE BLADE IS PROPERLY
TENSIONED BEFORE OPERATING
MACHINE.
15. KEEP LOOSE CLOTHING AND LONG
HAIR AWAY FROM MOVING CONVEY-
ORS!
1. DO NOT OPERATE WITH DULL OR
BADLY WORN BLADES. Dull blades
require more demand on the motor and are
less likely to cut precisely. Inspect blades
before each use.
2. NEVER POSITION
FINGERS OR THUMBS
IN LINE WITH THE CUT. Serious personal
injury could occur.
3. DO NOT OPERATE THIS BANDSAW
WITHOUT WHEEL GUARDS, PULLEY
GUARDS, AND BLADE GUARDS IN
PLACE.
4. WHEN REPLACING BLADES, make sure
the teeth face toward the front of the saw.
5. CUTS SHOULD ALWAYS BE FULLY
SUPPORTED against the side of the con-
veyor table and by the pressure rollers.
6. DO NOT BACK WORKPIECE AWAY
from the blade while the saw is running.
If you need to back the work out, stop the
bandsaw and wait for the blade to stop. DO
NOT twist or put excessive stress on blade
while backing work away.
7. BLADE SHOULD BE RUNNING AT FULL
SPEED before beginning a cut.
8. ALWAYS FEED STOCK EVENLY AND
SMOOTHLY. DO NOT change conveyor
speeds during a cut.
No list of safety guidelines can be com-
plete. Every shop environment is different.
Always consider safety first, as it applies
to your individual working conditions. Use
this and other machinery with caution and
respect. Failure to do so could result in
serious personal injury, damage to equip-
ment, or poor work results.
Like all machines there is danger associ-
ated with the Model G0504. Accidents are
frequently caused by lack of familiarity or
failure to pay attention. Use this machine
with respect and caution to lessen the pos-
sibility of operator injury. If normal safety
precautions are overlooked or ignored, seri-
ous personal injury may occur.
-10- G0504 16" Horizontal Resaw Bandsaw
Additional Safety Instructions for Hydraulics
4. STOP THE MACHINE IF YOU NOTICE
A HYDRAULIC LEAK. Allowing the
machine to continue running with a leak
may increase the hazard of the situation.
5. DEPRESSURIZE THE HYDRAULIC
SYSTEM BEFORE ATTEMPTING TO
ADJUST ANY HYDRAULIC LINES OR
FITTINGS. Stop the resaw, open the con-
veyor speed valves, and make sure the
pressure gauge reads 0 PSI.
6. DEPRESSURIZE THE HYDRAULIC
SYSTEM BEFORE ATTEMPTING ANY
MAINTENANCE OR SERVICE. Stop the
resaw, open the conveyor speed valves,
and make sure the pressure gauge reads
0 PSI.
7. REGULARLY INSPECT AND PER-
FORM THE PROPER MAINTENANCE
ON THE HYDRAULIC SYSTEM. A well-
maintained hydraulic system will have
much fewer problems and hazards than
a neglected system.
8. MAKE SURE ANY HYDRAULIC SYS-
TEM MAINTENANCE IS PERFORMED
IN A CLEAN AND DUST-FREE WORK
AREA. Remove any sawdust, grime or
water from hydraulic system openings or
components before maintenance. Always
use lint-free rags when wiping compo-
nents.
9. ONLY USE HIGH PRESSURE HYDRAU-
LIC HOSE AND STEEL HYDRAULIC
FITTINGS WHEN REPLACING COM-
PONENTS IN THE HYDRAULIC SYS-
TEM. DO NOT use brass or aluminum.
1. BE FAMILIAR WITH THE HAZARDS OF
HYDRAULIC INJECTION INJURIES.
— Leaking hydraulic fluid may have
enough pressure to penetrate skin.
Never use your hands to check for
suspected hydraulic leaks.
— Hydraulic fluid that is injected into
skin is a medical emergency that
may cause infection, disability,
amputation or death.
— The average injection injury may
be a small wound that has barely
broken the skin. DO NOT be fooled
by this type of injury. Immediately
get to an emergency medical facil-
ity!
— Minimizing the time between the
injury and when the injected mate-
rial is removed is critical to mini-
mizing the seriousness of the inju-
ry.
2. USE A PIECE OF CARDBOARD TO
CHECK FOR SUSPECTED HYDRAU-
LIC LEAKS. Pressurized hydraulic fluid
may cause injection injuries and can be
extremely hot. Never use your hands to
check for suspected hydraulic leaks.
3. PROTECT YOUR EYES AROUND
HYDRAULIC SYSTEMS. Safety glasses
may not always protect your eyes from
hot, pressurized fluid. The best way to
protect yourself is to stay away from leaks
until you can depressurize the system.
G0504 16" Horizontal Resaw Bandsaw -11-
A fire may occur if your particular electrical
configuration does not comply with local and
state codes. The best way to ensure compli-
ance is to check with your local municipality
or a qualified electrician.
Figure 1. A power disconnect is preferable to
high current plugs and receptacles.
Serious personal injury could occur if you
allow power to the machine before complet-
ing the setup process. DO NOT allow power
to the machine until instructed to do so.

Converting the Model G0504 to 440V operation
consists of 1) wiring the voltage transformer, 2)
replacing the overload relays with those provided
in the G0504 440V conversion kit, and 3) rewiring
the main motor and the elevation motor. A quali-
fied electrician must inspect all electrical modifi-
cations before connecting to power.
Figure 3. Inside of electrical box.
In the event of an electrical malfunction or break-
down, grounding provides a path of least resis-
tance for electric current to reduce the risk of
electric shock. This machine must be equipped
with an electric cord that has an equipment
grounding conductor. This conductor must be
grounded in accordance with all local codes and
ordinances.
Improper connections of the electrical-grounding
conductor can result in the risk of electric shock.
Check with a qualified electrician or one of our
service personnel if the grounding instructions
are not completely understood, or if you are in
doubt as to whether the machine is properly
grounded.
Electrocution or fire could
result if this machine is
not grounded correctly.
Make sure all electrical cir-
cuits are grounded before
you connect them to the
machine. DO NOT use the
Model G0504 if it is not
grounded.
Converting to 440VGrounding
To convert the Model G0504 to 440V:
1. Disconnect the resaw from the power
source!
2. At the voltage transformer, move the T1 wire
from the 220V terminal to the 440V terminal.

Removing Resaw
from Crate Pallet
To remove the resaw from the crate pallet:
1. Remove the lag bolts from the stand feet that
secure the resaw to the crate pallet.
2. Using a forklift, lift the resaw from the frame
location shown in Figure 11, and move it to
your predetermined location.
Figure 11. Lifting points for moving the resaw
with a forklift.
The Model G0504 is a
heavy machine that
weighs approximately
3300 lbs. Serious per-
sonal injury may occur if
safe moving methods are
not followed. To be safe,
you will need assistance
and power equipment
when moving the ship-
ping crate and remov-
ing the machine from the
crate.
Mounting Resaw to
the Floor
Although not required, we recommend that you
mount your new machine to the floor. Because
this is an optional step and floor materials may
vary, floor mounting hardware is not included.
Bolting to Concrete Floors
Lag shield anchors with lag bolts and anchor
studs (Figure 12) are two popular methods for
anchoring an object to a concrete floor. We sug-
gest you research the many options and methods
for mounting your machine and choose the best
that fits your specific application.
NOTICE
Anchor studs are stronger and more per-
manent alternatives to lag shield anchors;
however, they will stick out of the floor,
which may cause a tripping hazard if you
decide to move your machine.
Figure 12. Typical fasteners for mounting to
concrete floors.

Blade installation can be done by one person but
is easiest if done with two people.
To install and tension the blade:
1. Put on safety glasses and heavy leather
gloves.
2. Open the wheel cover to gain access to the
wheels.
3. Hold the blade from each side, and position
it in front of the wheels so the blade teeth are
facing the front of the machine.
4. Carefully fit the blade over each wheel,
and position it between the blade guides
as shown in Figure 13. Make sure the
teeth point toward the right-hand side of the
machine, as you are facing the front.

Guide Blocks
Each guide block consists of an upper and lower
ceramic block that stabilizes the blade from up/
down movement during operation.
The lower block is designed to remain in a fixed
position, and the upper block is designed to be
adjusted during each blade change. When the
machine is new, the lower block is set at the
factory and should not need to be adjusted (see
Section 8: Service Adjustments for more infor-
mation about the lower guide). The upper block,
however, should be adjusted every time you
install a new blade or re-install an old blade.

SECTION 6: OPERATIONS
Conveyor Controls
The Model G0504 features an infeed conveyor
and a return conveyor. The speed and engage-
ment controls of the conveyors are controlled by
the conveyor control lever. The farther the control
lever is pushed forward, the faster the conveyors
will move.

The blade height is defined as the distance
between the conveyor table and the bottom face
of the bandsaw blade. There is an internal limit
switch that will not allow the blade to be adjusted
closer than 1⁄4" to the conveyor table. Note—Use
the “Blade Memory Function” described in the
next subsection when you want to make resaw
cuts thinner than 1⁄4", and be sure to cut from the
top of the workpiece.
The blade height can be adjusted by using the
keypad, or by pressing the UP and DOWN con-
trol panel buttons. After using either method of
adjustment, the digital display will indicate the
current blade height.
To set the blade height with the UP and DOWN
control panel buttons:
1. Turn the control panel POWER ON switch
clockwise to supply power to the control
panel.
2. Press the UP button to move the blade up
and press the DOWN button to move the
blade down. Watch the digital display to
gauge the blade height.
To set the blade height with the keypad:
1. Turn the control panel POWER ON switch
clockwise to supply power to the control
panel.
2. Press the FUNC key.
3. Enter the desired blade height to the nearest
hundredth's place. For example, if you want
the blade height to be 2", press 2, 0, 0 on
the keypad. If you want the blade height to
be 3⁄4", press 7, 5.
4. After the blade height has been entered,
press the START key.
Setting Blade Height
The digital display indicates the distance between
the conveyor table and the bottom face of the
bandsaw blade. The digital display needs to be
calibrated to ensure that the displayed blade
height and the actual blade height are the same.
To calibrate the digital display:
1. Resaw a
piece of scrap wood. See “Resawing”
on Page 27 for more information.
2. Measure the thickness of the workpiece that
was cut off between the conveyor table and
the blade. Note—Use a precise measuring
tool such as calipers or a micrometer.
3. Press the SET key.
4. Enter the thickness value of the cut-off
piece measured in Step 2. For example, if
the thickness is 1", press 1, 0, 0 on the key
pad.
5. Press and hold the SET key for approxi-
mately 5 seconds or until the display stops
flashing.
The digital display is now calibrated and all blade
height values displayed will be the same as the
actual distance between the conveyor table and
the bottom face of the bandsaw blade.
Calibrating Digital
Display
-26- G0504 16" Horizontal Resaw Bandsaw
The blade memory button lowers the blade a pre-
determined distance each time it is pressed. This
allows you to make a series of cuts from the top
side of the workpiece, all of the same thickness.
Be sure to add the blade kerf to the desired
thickness of the cut-off pieces when setting the
memory function. For example, if you want your
cut-off pieces to be 1" thick and the kerf of the
blade is 0.06", the memory function needs to be
set to 1.06".
The blade memory function is also used when
you want to make resaw cuts thinner than 1⁄4".
Because the blade cannot be adjusted closer than
1⁄4" to the table, resaw cuts thinner than 1⁄4" need
to be cut from the top side of the workpiece.
To set the memory function:
1. Turn the control panel POWER ON switch
clockwise to supply power to the control
panel.
2. Press the FUNC key.
3. Enter the distance, to the nearest hun-
dredth's place, that you want the blade to
lower. For example, if you want the blade to
lower 2.06", press 2, 0, 6 on the key pad. If
you want the blade to lower 0.56", press 5,
6.
4. Press and hold the SET key for approxi-
mately 5 seconds or until the display stops
flashing.
5. Press the MEMORY button and the blade
will automatically lower the distance set into
the memory function.
Note—For best results, make a few cuts while using
the MEMORY button, measure the workpiece,
and adjust the memory setting according to the
measurements of the cut-off workpiece.
Setting Memory
Button
The memory preset keys (A, B, C, D) allow four
dimension sizes to be saved and recalled.
For example, if you have 500 pieces to resaw and
the starting size is 2" thick on all of them, then
you can save 2" in one of the memory keys. After
cutting down each piece, press that memory pre-
set key to return to the starting height of 2" for the
next whole piece.
To store a height in the A memory preset
key:
1. Press the A key. The current preset height
flashes on the display.
2. Enter the height you wish to store. For exam-
ple if you want to store 2" as the height",
press 2, 0, 0 on the key pad.
3. Press and hold the A key for 3 seconds. The
display zeros out and stops flashing.
To use the stored memory preset in the A
key:
1. Press the A key. The current preset height
flashes on the display.
2. Press the START key on the key pad. The
blade moves to the stored height dimen-
sion.
Note—To stop a stored memory preset from
moving to its stored height, press the STOP

Blade Information
Blade choices are limited due to the specialized
nature of the Model G0504. The only variables
when selecting a blade are the type of cutting
tooth and the number of teeth-per-inch (Tooth
Pitch).
Blade Tooth Type
Carbon Steel—The least expensive type, car-
bon steel blades are adequate for most cutting
applications; however, they dull quickly and for
economical reasons they are usually replaced
rather than resharpened.
Carbide-Tipped—The most expensive type, car-
bide-tipped blades are designed for continuous
use in production shops. They hold a sharp
edge longer than carbon steel and they can be
resharpened many times before needing to be
replaced.
Tooth Pitch (TPI)
Tooth pitch refers to the number of teeth-per-
inch. The more teeth-per-inch, the smoother the
resulting cut, but the feed rate must be relatively
slow. The less teeth-per-inch, the rougher the
resulting cut, but the feed rate can be set faster.
Some trial and error may be necessary to find
the right combination of cut quality, tooth pitch
and feed rate.
Blade Care
The resaw blade is a delicate piece of steel that
is subjected to tremendous strain. You can obtain
longer use from the blade if you give it fair treat-
ment and always use the appropriate feed rate
for your operation.
A clean blade will perform much better than a
dirty blade. A dirty blade passes through the
cutting material with much more resistance than
a clean blade. This extra resistance will also
cause unnecessary heat. Maintain your blades
with a cutting blade lubricant like SLIPIT® (Model
G5562/3 in the Grizzly Catalog).
Blade Length
The required blade length for the Model G0504
is 180".
Blade Width
The required blade width for the Model G0504
is 1".
Blade Breakage
Blade breakage is unavoidable, in some cases,
since it is the natural result of the peculiar stress-
es placed on the blade. Blade breakage is also
due to avoidable circumstances, which is most
often the result of poor care or judgement on the
part of the operator when mounting or adjusting
the blade or support guides.
The most common causes of blade breakage
are:
• Not releasing blade tension after use.
• Faulty alignment or adjustment of the
guides.
• Using a blade with a lumpy or improperly
finished braze or weld.
• Feeding the workpiece too fast.
• Tooth dullness or absence of sufficient set.
• Excessive or too little blade tension.
• Running the bandsaw excessively when not
resawing.

To ensure optimum power transmission from the
motor to the blade and to the hydraulic pump,
the V-belts must be in good condition (free from
cracks, fraying and wear) and operate under
proper tension. Check the V-belts at least every 3
months; more often if the bandsaw is used daily.
See Section 8: Service Adjustments for instruc-
tions on properly tensioning the belts or for
replacing the belts, if needed.
Inside Wheel Cover
To keep the bandsaw working properly, regularly
open the wheel cover and vacuum sawdust.
Conveyor Belts
Use compressed air to clean the built-up sawdust
from the conveyor belts. Eye injuries frequently
occur when cleaning with compressed air—wear
safety glasses to protect yourself! Also wear a
dust mask or respirator to protect your lungs from
airborne dust particles.
Elevation Columns
Use a dry rag to remove sawdust from the eleva-
tion columns and wipe the them down with a light
coat of oil.
Painted Surfaces
These areas may be cleaned with a dry or damp
rag; however, make sure you DO NOT clean
bare metal surfaces with a damp rag or they may
rust.
Motor
Vacuum dust off of the motor on a regular basis.
Built up dust acts as an insulator, making it dif-
ficult for the motor to dissipate heat.
Hydraulic Components
Keep hydraulic components free of sawdust,
especially before working on them, to avoid con-
tamination of the hydraulic system.
Always be aware of the condition of your machine.
Routinely check the condition of the following
items and repair or replace as necessary:
• Loose mounting bolts
• Worn switch
• Worn or damaged blade
• Worn or damaged support bearings or guide
bearings
Always disconnect
power to the machine
before performing main-
tenance. Failure to do
this may result in seri-
ous personal injury.
Except for the bearings that are fitted with grease
fittings, the other bearings are sealed and pre-
lubricated and require no lubrication during their
usable life. All bearings are standard sizes, and
replacements can be purchased from our parts
department or a bearing supply store.

Check the hydraulic fluid level daily.
The hydraulic system controls the movement
of the conveyor belts. In order for this system
to function properly and operate at the correct
temperature, the hydraulic fluid level in the tank
should be 2⁄3 full between the fill lines on the fluid
sight window, which is located on the front of the
tank (see Figure 30).
To add hydraulic fluid, remove the breather
cap shown in Figure 30. Use an ISO VG 10—
Antiwear 10 Hydraulic Fluid or equivalent.
The hydraulic system minor service consists of
changing the fluid filter, cleaning the breather
cap and filler screen, and inspecting the hydraulic
fluid for signs of thermal breakdown, dust con-
tamination, and water contamination.
Perform a “Minor Service” every 960 hours or
every 6 months of regular use.
Figure 31. Removing filter.
To change the filter:
1. Read and understand the hydraulic safe-
ty instructions on Page 6 before continu-
ing!
2. Thoroughly clean the entire area around the
filter to remove all dust. (Getting dust into the
hydraulic system will contaminate it.)
3. Remove the filter by unscrewing it from the
housing (Figure 31).
Inspect and clean the breather cap and filler
screen every 40 hours of regular use.
The breather cap is vented to allow the hydraulic
system to breathe during operation. Below the
breather cap is a plastic filler screen.
Visually inspect both the breather cap and the
plastic filler screen. If there is visual contami-
nation, clean both items with solvent and com-
pressed air. Allow them to completely dry before
installing back in the tank.
The hydraulic system on this machine cre-
ates very high pressure and the hydraulic
fluid gets hot. Always stop the resaw, open
the conveyor speed valves, make sure the
pressure gauge reads 0 PSI, and make sure
the fluid cools down before removing any
lines or servicing the hydraulic system.

4. Rub clean hydraulic fluid along the O-ring on
the bottom of the new filter.
5. Thread the new filter into the filter housing
and tighten by hand.
To inspect the hydraulic fluid:
1. Look at the color of the hydraulic fluid in the
sight window.
— If the fluid is milky in appearance, then the
hydraulic fluid is contaminated with water.
Repair leaks or fix the source of the prob-
lem and perform a major service.
— If the fluid is dark brown or opaque, then
the hydraulic fluid is severely contaminat-
ed or thermal breakdown has occurred.
Correct the source of the contamination
or which component is causing thermal
breakdown, and perform a major service.
2. Smell the hydraulic fluid (remove breather
cap).
— If the fluid smells rancid or burnt, then ther-
mal breakdown has most likely occurred.
Correct the component that is causing
thermal breakdown and perform a major
service.
The hydraulic tank, when filled correctly at the
sight window, holds approximately 13.5 gallons
of hydraulic fluid. Before draining the hydraulic
fluid, make sure you have a drain pan that will
hold that much fluid or make sure that you are
prepared to drain the tank, plug the tank, empty
your drain pan, drain the tank, and so forth.
To drain the hydraulic fluid:
1. Read and understand the hydraulic safety
instructions on Page 8!
2. Place your drain pan under the drain plug
(Figure 32) and remove the drain plug.
Figure 32. Drain plug for hydraulic tank.
Hydraulic System
Major Service
The hydraulic system major service consists of

Adjusting V-Belt
Tension
Properly tensioned V-belts help the Model G0504
operate at its best. However, adjusting the V-
belts is not an exact science and does require
personal judgement. Adjusting the belts too loose
will decrease the performance of the machine
and adjusting the belts too tight may cause pre-
mature wear of the bearings and other compo-
nents attached to the belts.
On the Model G0504 there is a triple-drive V-belt
system that connects the motor to the wheel
pulley and a single-drive V-belt system that con-
nects the wheel pulley to the hydraulic pump
(Figure 35).
Figure 35. G0504 V-belts.
To adjust the V-belt tension for the saw
wheels:
1. Disconnect the resaw from the power
source!
2. Adjust the belt tension by using the motor
mount hex bolts shown in Figure 36.
3. When the belts are properly tightened, lock
the bolts in place with the jam nuts.
To adjust the tension for the hydraulic pump
V-belt:
1. Remove the small pulley cover from the
pump seat.
2. Adjust the belt tension by loosening the cap
screws shown in Figure 37.
Figure 37. Pump seat cap screws.
3. Slide the pump left/right as needed until the
belt has the proper tension.
4. Tighten the cap screws to lock the pump
seat in place.
G0504 16" Horizontal Resaw Bandsaw -37-
Replacing V-Belts
If the belts deteriorate or break, they will need
to be replaced. When replacing one belt, you
should replace all of them at the same time to
ensure uniform belt tension and save time.
To replace the V-belts:
1. Disconnect the resaw from the power
source!
2. Read the previous subsection titled “Adjusting
V-Belt Tension” to become familiar with the
V-belt tension controls.
3. Adjust the motor mount nuts down as far as
they will go.
4. Remove all three V-belts that connect the
motor to the wheel pulley. (The easiest way
to take the belts on/off is to roll them on/off
the pulley one at a time. The belts can then
be fit over the wheel.)
5. Remove and replace the hydraulic pump
V-belt. (Refer to Page 35 for information on
how to loosen/tension this V-belt.)
6. Replace the three V-belts as a matching set.
Matching sets can be identified by the batch
number on the belt—NOT to be confused
with the size markings of the belt.
7. Tension the newly installed V-belts.
Figure 38. Test board with measurements.
The main conveyor table height can be adjusted
left-to-right and front-to-back to make the table
parallel to the blade in both directions. This is an
involved procedure that requires you to cut up a
piece of test stock and make many repeat adjust-
ments. Because of the complexity of this proce-
dure, we will first give instructions on checking
the table, so that you can be sure you need to
perform the adjustment.
Before attempting these procedures, you need
to have a perfectly squared up piece of stock
that is as wide as possible and is at least two
feet long. The wider the stock, the more accurate
your procedure will be (we recommend using the
maximum width that the resaw will allow). Also,
you need to make sure that your blade is in good
condition, the blade is tracked/tensioned properly
and the blade guides are properly adjusted.
To check the main conveyor table alignment:
1. Cut a 1⁄4" slice off of your squared-up test
stock.
2. Using a dial caliper, measure the thickness
of the cut piece at all four corners and in
even locations along the edges of the stock.
As you take these measurements, write them
directly on the stock, near the location where
you took the measurement (see Figure 38).
Adjusting Main
Conveyor Table
-38- G0504 16" Horizontal Resaw Bandsaw
3. Study the written measurements on your
test piece. Note—DO NOT place too much
importance on the first and last six inches of
the board, because the board will only have
been under one pressure roller during that
part of the cut.
— If the measurements are more than 0.030"
different from one side to the other, you
should adjust the conveyor table.
To adjust the conveyor table:
1. Disconnect the resaw from the power
source!
2. Use your test board to determine which
direction the conveyor table needs to be
moved. For example, if the right side of the
board was thicker than the left side—you
will need to move either the right side of the
conveyor up or move the left side of the con-
veyor down.
3. Adjust the four adjustment bolts that control
the conveyor table height as determined
from Step 2. Note—For adjustment bolt
locations see the adjustment bolt shown in
Figure 39.
Figure 39. Conveyor table adjustment bolts
(1 of 4 shown).
4. Tighten the lock nuts on the adjustment
bolts, connect the resaw to the power, and
repeat the checking and adjusting Steps
until the measurements on your cut piece
are within 0.030".
Tracking Conveyors
“Tracking” the conveyor belts means balancing
the way they ride on the end rollers. The convey-
ors are tracking correctly when they are centered
between the roller brackets on each side of the
conveyor. If the conveyor belts start rubbing
against the roller brackets, then you need to track
them as described.
To set the conveyor tracking:
1. Loosen the two roller bracket cap screws
(shown in Figure 40) about 3⁄4 of a turn. Do
this on the both sides of the conveyor.
2. Loosen the rear adjustment nuts away from
the bracket plates on both sides of the con-
veyor.
3. Start the conveyor belt.
4. On the side that the belt tracks toward, turn
the front adjustment nut counter-clockwise
half of a turn, and watch the belt tracking.
Note—The effect of the adjustment can
sometimes take two minutes before the
results are fully apparent.
— If the tracking was not corrected by this
adjustment, proceed to Step 5. If the
tracking was corrected, skip to Step 6.
Figure 40. Roller bracket cap screws and
adjustment nuts.

5. On the side that the belt tracks away from,
turn the front adjustment nut clockwise half
of a turn, and watch the belt tracking.
— If the tracking was not corrected by this
adjustment, repeat Step 4.
6. When the conveyor belt is tracking in the
center of the roller brackets, run the con-
veyor for at least two minutes to ensure that
it will remain tracking correctly.
7. Tighten the rear adjustment nuts against the
bracket plates, then tighten the front adjust-
ment nuts against the bracket plates to make
sure that the tracking adjustment will not
slowly change during normal operation.
Replacing Conveyors
Although the conveyor belts have slight differenc-
es in size and access, the replacement instruc-
tions are the same.
To replace the conveyor belts:
1. Start the conveyor belt that you want to
replace.
2. Stop the conveyor belt when the conveyor
belt seam (see Figure 41) is accessible.
Figure 41. Conveyor belt seam.
-40- G0504 16" Horizontal Resaw Bandsaw
3. Disconnect the resaw from the power
source!
4. Loosen the roller bracket (see Figure 42) by
turning the roller bracket cap screws 3⁄4 of a
turn.
Figure 42. Roller bracket cap screws and
adjustment nuts.

5. Loosen the rear adjustment nuts away from
the bracket plate.
6. Mark the front adjustment nut with a felt-
tipped pen or a piece of tape, and thread
the front adjustment nut all the way up, while
keeping track of the number of full turns that
you moved the nut.
Note—Write the number of turns down, so
you do not forget. Remembering this number
is an important part of the re-assembly pro-
cess.
7. Slide the roller brackets toward the body of
the resaw to loosen the belt.
8. Remove the stiff cable from the center of the
seam to separate it.
9. Remove the old conveyor belt from the con-
veyor table, and replace the new conveyor
belt in its place.
10. Mesh the seam “teeth” together on the new
belt, and insert the stiff cable into the center
of the seam to lock it together.
11. Slide the roller brackets away from the body
of the resaw to tighten the belt.
12. Turn the front adjustment bolts the exact
number of rotations that you turned them
when you loosened them.
Note—The new belt may be tighter than the
old one because it has not been broken-in. If
this is the case, deduct one or two turns from
your original number of turns.
13. Run the conveyor belt to check the tracking.
If the belt starts tracking to one side, stop the
resaw and perform the “Tracking Conveyors”
instructions that are located on Pages 38.
G0504 16" Horizontal Resaw Bandsaw -41-
Blade Tracking and
Wheel Alignment
Blade tracking on the Model G0504 consists
of adjusting the wheels to be nearly coplanar
(coplanar=both wheels even and parallel), but
having the outside edge of the wheel approxi-
mately 0.020"-0.040" behind the inside edge of
the wheel to compensate for wheel toe-in when
the blade is fully tensioned.
Because of the large size of this machine and
the wheel toe-in factor, this procedure is time
consuming and requires a great deal of trial and
error. Make sure you really need to perform this
procedure before attempting it.
Also, to complete this procedure you will need to
make four precision gauge blocks and have a 6'
long straightedge.
To adjust the wheels to be coplanar:
1. Disconnect the resaw from the power
source!
2. Open the wheel cover.
3. Remove the blade.
4. Using 2x4’s, make four precision gauge
blocks to the specifications shown in Figure
43.
Figure 43. Precision gauge block dimensions.
Figure 44. Precision gauge blocks clamped in
position on wheels.
Figure 45. Straightedge placement when check-
ing the upper portion of the wheels.
5. Clamp the gauge blocks to the wheels as
shown in Figure 44.
6. Place the straightedge across the top of the
gauge blocks, as shown in Figure 45, and
examine how the wheels line up with each
other.

Figure 46. Overhead view of straightedge on
blade wheel gauge blocks.
Figure 47. Tension wheel adjustment bolts.
Figure 48. Drive wheel adjustment controls
(fourth bolt hidden in this picture).
— If the wheels are properly aligned, the
straightedge will touch both inside gauge
blocks and there will be a 0.020"–0.040"
gap between the straightedge and the
outside gauge blocks, as shown in Figure
46. If this is the case, skip to Step 9.
— If the wheels are not positioned as shown
above, determine which direction they
need to move in order to be correct, then
proceed to Step 7 to begin the adjustment
process.
7. Look at the backside of the wheel guard and
learn the controls shown in Figures 47 & 48
by reading the text that follows.
Adjustment
Screws
Drive Wheel
Adjustment
Bolts
Movement Direction—The bolt position
around the wheel shaft determines the part
of the wheel that will move when that bolt is
turned.
Moving Forward—To move part of the
wheel forward, loosen the appropriate lock
bolts the same amount that you will tight-
en their neighboring adjustment bolts. (By
“appropriate” we mean the bolts that control
the direction that your wheel needs to be
moved.) In the case of the main drive wheel
adjustments, always loosen the jam nuts
before moving the adjustment bolts, and
always tighten the jam nuts after moving the
adjustment bolts.
Moving Backward—To move part of the
wheel backward, loosen the appropriate
adjustment bolt, then tighten the neighboring
lock bolt.
8. Adjust the wheels as necessary until the
wheel position is correct when checked with
the straightedge and continue to Step 9.

Figure 49. Straightedge placement when
checking the lower portion of the wheels.
Figure 50. Overhead view of wheel position
when checking with a straightedge and the
blade is installed and tensioned.
9. Place the straightedge across the bottom of
the gauge blocks, as shown in Figure 49.
The wheels should line up in the same man-
ner as described in Step 6.
— If they do not, follow Steps 7–8 to correct
them.
10. After the wheels are positioned correctly,
install and tension the blade, and adjust the
guide bearings out of the way of the blade.
11. Check the new position of the wheels. Ideally
the gauge blocks will all be perfectly aligned
with each other, as illustrated in Figure 50.
— If the gauge blocks are aligned within
0.040" of each other, continue to Step
12.
— If the gauge blocks are positioned more
than 0.040" from each other, repeat Steps
6 & 9, and make the new adjustments
according to the change you noticed after
tensioning the blade.
12. Remove the gauge blocks and clamps, and
spin the wheels by hand in the direction of
normal operation to check the blade track-
ing. You can fine tune the blade tracking by
adjusting the blade tension up or down—just
make sure to stay in the color range on the
tension scale for your particular blade.
13. After the blade is tracking correctly, prepare
the saw for a test run by adjusting the guide
bearings, closing the wheel cover, and con-
necting the machine to the power source.
14. Test run the resaw and repeat this entire
section if the blade does not track correctly.
