WARNING

Some dust created by power sanding, sawing, grind­ing, drilling, and other construction activities contains
chemicals known to the State of California to cause
cancer, birth defects or other reproductive harm.
Some examples of these chemicals are:

• Lead from lead-based paints.

• Crystalline silica from bricks, cement, and
other masonry products.

• Arsenic and chromium from chemically treated
lumber.

Your risk from these exposures varies, depending on
how often you do this type of work. To reduce your
exposure to these chemicals: work in a well ventilated
area, and work with approved safety equipment, such
as those dust masks that are specially designed to fil­ter out microscopic particles.

Safety Instructions For Power Tools

SECTION 1: SAFETY

5. KEEP CHILDREN AND VISITORS

AWAY. All children and visitors should be

kept at a safe distance from work area.

6. MAKE WORKSHOP CHILD PROOF with
padlocks, master switches, or by removing
starter keys.

7. NEVER FORCE TOOL. It will do the job
better and safer at the rate for which it was
designed.

8. USE RIGHT TOOL. DO NOT force tool or
attachment to do a job for which it was not
designed.

1. KEEP GUARDS IN PLACE and in working
order.

2. REMOVE ADJUSTING KEYS AND
WRENCHES. Form a habit of checking to

see that keys and adjusting wrenches are
removed from tool before turning on.

3. KEEP WORK AREA CLEAN. Cluttered
areas and benches invite accidents.

4. NEVER USE IN DANGEROUS ENVIRON­MENT. DO NOT use power tools in damp

or wet locations, or where any flammable
or noxious fumes may exist. Keep work
area well lighted.

For Your Own Safety Read Instruction

Manual Before Operating This Equipment

Indicates an imminently hazardous situation which, if not avoided,
WILL result in death or serious injury.

Indicates a potentially hazardous situation which, if not avoided,
COULD result in death or serious injury.

Indicates a potentially hazardous situation which, if not avoided,
MAY

result in minor or moderate injury. It may also be used to alert

against unsafe practices.

This symbol is used to alert the user to useful information about
proper operation of the equipment.

The purpose of safety symbols is to attract your attention to possible hazardous conditions.
This manual uses a series of symbols and signal words which are intended to convey the level
of importance of the safety messages. The progression of symbols is described below.
Remember that safety messages by themselves do not eliminate danger and are not a substi­tute for proper accident prevention measures.

NOTICE

G0527 18" Wide Belt Sander -3-

9. USE PROPER EXTENSION CORD. Make
sure your extension cord is in good condi­tion. Conductor size should be in accor­dance with the chart below. The amperage
rating should be listed on the motor or tool
nameplate. An undersized cord will cause
a drop in line voltage resulting in loss of
power and overheating. Your extension
cord must also contain a ground wire and
plug pin. Always repair or replace exten­sion cords if they become damaged.

Minimum Gauge for Extension Cords

10. WEAR PROPER APPAREL. DO NOT
wear loose clothing, gloves, neckties,
rings, bracelets, or other jewelry which may
get caught in moving parts. Non-slip
footwear is recommended. Wear protective
hair covering to contain long hair.

11. ALWAYS USE SAFETY GLASSES. Also
use face or dust mask if cutting operation is
dusty. Everyday eyeglasses only have impact
resistant lenses, they are NOT safety glasses.

12. SECURE WORK. Use clamps or a vise to hold

work when practical. It’s safer than using your
hand and frees both hands to operate tool.

13. DO NOT OVER-REACH. Keep proper

footing and balance at all times.

14. MAINTAIN TOOLS WITH CARE. Keep
tools sharp and clean for best and safest
performance. Follow instructions for lubri­cating and changing accessories.

Safety Instructions For Power Tools

15. USE RECOMMENDED ACCESSORIES.

Consult the owner’s manual for recom­mended accessories. The use of improper
accessories may cause risk of injury.

16. REDUCE THE RISK OF UNINTENTION-

AL STARTING. On machines with magnet-

ic contact starting switches there is a risk of
starting if the machine is bumped or jarred.

before adjusting or servicing. Make sure
switch is in OFF position before reconnecting.

17. CHECK DAMAGED PARTS. Before fur­ther use of the tool, a guard or other part
that is damaged should be carefully
checked to determine that it will operate
properly and perform its intended function.
Check for alignment of moving parts, bind­ing of moving parts, breakage of parts,
mounting, and any other conditions that
may affect its operation. A guard or other
part that is damaged should be properly
repaired or replaced.

18. NEVER LEAVE TOOL RUNNING UNAT­TENDED. TURN POWER OFF. DO NOT

leave tool until it comes to a complete stop.

19. NEVER OPERATE A MACHINE WHEN
TIRED, OR UNDER THE INFLUENCE OF
DRUGS OR ALCOHOL. Full mental alert-

ness is required at all times when running a
machine.

20. NEVER ALLOW UNSUPERVISED OR
UNTRAINED PERSONNEL TO OPER­ATE THE MACHINE. Make sure any

instructions you give in regards to machine
operation are approved, correct, safe, and
clearly understood.

21. IF AT ANY TIME YOU ARE EXPERIENC­ING DIFFICULTIES performing the intend-

ed operation, stop using the machine! Then
contact our service department or ask a
qualified expert how the operation should
be performed.

Commentary

SECTION 2: INTRODUCTION

-6-

G0527 18" Wide Belt Sander

The Model G0527 has three motors that are
wired to operate on a 220V single-phase power
source. They will draw the following loads:

Sanding Drum Motor ............................30 Amps

Conveyor Feed Motor ..........................3.8 Amps

Elevation Motor ......................................3 Amps

Use the following guidelines when choosing a cir­cuit breaker (circuit breakers rated any higher are
not adequate to protect the circuit):

Circuit Breaker ............................40 Amp, 2 Pole

Always check to see if the wires in your circuit are
capable of handling the amperage load from your
machine. If you are unsure, consult a qualified
electrician.

Electrocution or a fire
can result if the machine
is not grounded correct­ly. Make sure all electri­cal circuits are ground­ed. DO NOT use the
machine if it is not
grounded.

In the event of an electrical short, grounding pro­vides electric current a path of least resistance to
reduce the risk of electrical shock to the operator.
Ground the power cord and this machine in
accordance with all local codes and ordinances.

Operating this machine when it is not properly
grounded can result in electric shock or electro­cution.

We have covered some basic electrical
requirements for the safe operation of your
machine. These requirements are not nec­essarily comprehensive. You must be sure
that your particular electrical configuration
complies with local and state codes.
Ensure compliance by checking with your
local municipality or a licensed electrician.

Because of the high amperage draw from this

Site ConsiderationsClean Up

The unpainted surfaces are coated with a waxy
oil to protect them from corrosion during ship­ment. Remove this protective coating with a sol­vent cleaner or citrus-based degreaser such as
Grizzly’s G7895 Degreaser. To clean thoroughly,
some parts may need to be removed. For opti-

mum performance from your machine, make
sure you clean all moving parts or sliding
contact surfaces that are coated. Avoid chlo-

rine-based solvents as they may damage painted
surfaces should they come in contact.

Gasoline and petroleum
products have low flash
points and could explode
if used to clean machin­ery. DO NOT use gaso­line or petroleum prod­ucts to clean the machin­ery.

Smoking near solvents
could ignite an explosion
or fire and cause serious
injury. DO NOT smoke
while using solvents.

Lack of ventilation while
using solvents could
cause serious personal
health risks, fire, or
environmental hazards.
Always work in a well
ventilated area to pre­vent the accumulation
of dangerous fumes.
Supply the work area
with a constant source
of fresh air.

Unsupervised children
and visitors inside your
shop could receive seri­ous personal injury.
Ensure child and visitor
safety by keeping all
entrances to the shop
locked at all times. DO
NOT allow unsupervised
children or visitors in the
shop at any time.

Weight Load

The Model G0527 weighs 890 lbs and has a 29"
x 16

3

⁄4" footprint. Most shop floors should be suf­ficient to carry the weight of the machine.
Reinforce the floor if you question its ability to
support the weight.

Working Clearance

Working clearances can be thought of as the dis­tances between machines and obstacles that
allow safe operation of every machine without
limitation. Consider existing and anticipated
machine needs, size of material to be processed
through each machine, and space for auxiliary
stands or work tables. Also, consider the relative
position of each machine to one another for effi­cient material handling.

Work Area Lightening

Lighting should be bright enough to eliminate
shadow and prevent eye strain.

G0527 18" Wide Belt Sander -15-

Floor Mounting

To mount the sander to the floor:

The sander needs to be mounted in a level loca­tion where it can be easily serviced from all sides.
Also, consider the largest workpiece you might
need to sand before deciding on a final position.

Mount the sander to wooden floors with

1

⁄2" lag
bolts and washers. Mount the sander to concrete
floors with

1

⁄2" anchor-style bolts designed for

concrete applications. Note—Be sure to carefully

follow the anchor bolt manufacturer’s instructions.

Beginning Assembly

Loose hair and clothing
could get caught in
machinery and cause
serious personal injury.
Keep loose clothing
rolled up and long hair
tied up and away from
machinery.

Sharp edges on metal
parts may cause person­al injury. Examine the
edges of all metal parts
before handling.

This section will cover the basic assembly and
adjustment instructions needed to begin opera­tion. Complete the assembly in the order provid­ed in this manual and then read the remaining

G0527 18" Wide Belt Sander

Pressure Rollers

It is absolutely essential to keep the pres­sure rollers set below the level of the sand­ing roller. If the pressure rollers are even, or
higher than the sanding roller, the wood
could be propelled from the sander at a
high rate of speed. This situation could
cause serious personal injury.

To check the pressure roller height:

1. Disconnect the sander from the power
source!

2. Place a piece of scrap wood of uniform thick-

ness across the table so it spans both the
front and rear pressure rollers at the same
time.

3. With the air pressure connected and the
sanding belt installed and tensioned, manu­ally raise the table and verify that the board
touches both pressure rollers before it touch­es the sanding belt. Note—If the board does

not touch both pressure rollers before it
touches the sanding belt, then the pressure
rollers must be adjusted before operation.
See "Pressure Rollers" on page 31 for step­by-step instructions on how to do this.

The pressure rollers have been set at the factory,
but for safety, you should verify that they are set
below the level of the sanding roller.

Before starting the machine:

1. Read this manual and make sure you take all

safety precautions before operating this
machine.

2. Make sure the machine is connected to an
air compressor and the pressure gauge
reads 75 PSI.

3. Make sure all tools or foreign objects have
been removed from the machine.

4. Review Section 3: Circuit Requirements on
page 6 and make sure all the wiring is cor-

rect.

Loose hair and clothing
could get caught in
machinery causing seri­ous personal injury.
Keep loose clothing
rolled up and long hair
tied up and away from
machinery.

Projectiles thrown from
the machine could cause
serious eye injury. Wear
safety glasses during
start up.

Serious personal injury could result if the
machine is connected to the power source
during assembly or adjustment. Wait until
the machine is turned off, unplugged and all
working parts have come to a complete stop
before you attempt to assemble or adjust the
machine!

Your safety is important! Please follow the
warnings below during this entire section:

Choosing Sandpaper

The grit you choose will depend on the type of
work, the species of wood and the stage of fin­ishing. Below is a chart that groups abrasives into
different categories and shows which grits fall into
each one. We recommend using aluminum oxide
sanding belts for best results.

The general rule of thumb is to sand a workpiece
with progressively higher grit numbers, with no
one grit increase of more than 50; however, the
type of wood and desired finish will determine the
best grit to use.

Before Sanding

NOTICE

#100 and #150 grit sanding belts are includ­ed with the Model G0527.

To avoid serious personal injury, read and
become familiar with the entire instruction
manual before using the Model G0527.

Damage to your eyes, lungs, and ears
could result from failure to wear safety
glasses, a dust mask, and hearing protec­tion while sanding with this machine.

Loose hair and clothing

32.8 FPM.

Figure 13. Table drive chain and sprockets.

To change feed belt speed:

1. Disconnect the sander from the power
source!

2. Remove the cap screw that secures the feed

belt motor cover.

3. Loosen the motor mount bolts so that the
motor will slide up enough to get the chain off
the sprockets.

4. Determine which speed is best for your appli­cation and place the chain accordingly.

5. Tighten the motor mount bolts loosened in
step 3.

6. Replace the motor cover and secure it with

the cap screw removed in step 2.

The amperage meter is located above the control
panel as shown in

Figure 14.

Use the meter to
monitor the amperage load on the machine while
performing sanding operations.

Figure 14. Amperage meter.

Normal Operating Load

G0527, single-phase, 220V....................35 amps

If the sanding operation draws current in excess
of this limit, you run the risk of tripping the circuit
breaker and the overload relays in the electrical
box.

NOTICE

There are many variables that affect the
overall load on the sander. Depth of cut, the
species of wood being sanded, the grit size
on the sanding belt, and the feed rate, all
contribute to the load on the sander. As a
general rule, always start with a small load
and work your way up. DO NOT push your
machine to its maximum load; instead,
make multiple passes, install a coarser grit
paper, or reduce the feed rate.

Typically, no more than 0.5mm (approx. 1⁄64") of
material is removed during each pass. Attempts
to remove too much material can cause jamming,
wood burning, rapid paper wear or tearing, poor
finish and belt slippage.

The following is the correct sanding operating
procedure:

1. Wear safety glasses, a dust mask, and
hearing protection!

2. Turn on the dust collector.

3. On the initial pass, adjust the table to

approximately

1

⁄4" greater than the thickness

of the workpiece. Note—This reduces the

chance of jamming the sander on undetect­ed high points on the workpiece.

4. Continue to raise the table

1

⁄16" between each
successive pass until the sander begins to
sand the workpiece.

NOTICE

It may be necessary to send wide stock
through the sander two or three times
between table height adjustments. This
reduces the likelihood of burning the wood
and produces a more consistent finished
thickness.

G0527 18" Wide Belt Sander

Servicing Brakes

Eventually the brake pads will wear out. Checking
and replacing these is a simple project that can
be done in the shop, with the exception of having
the rotor resurfaced.

To check the brake pads:

1. Disconnect the sander from the power
source and remove air pressure com­pletely!

2. Remove the four screws that secure the

motor cover on the right-hand side of the
machine. Note—The brake caliper is located
underneath the rotor, which is attached to the
motor arbor.

3. The brake pads consist of a metal plate with
a composite pad. With a fine ruler, measure
the thickness of the composite pad only. If
one of the pads is below

1

⁄8" (approx. 3mm),

replace both.

To perform a pad replacement:

1. Disconnect the sander from the power

source and remove air pressure com­pletely!

2. Remove the nuts from the two mounting

bolts. There are two snap rings on the
mounting pins behind the bracket. Remove
these.

Figure 15. Disc brake components.

3. Pull the mounting pins out of the caliper

bracket and remove the air line from the
caliper. The caliper should now be able to be
removed as in Figure 15.

4. The brake pads are secured to the caliper
with cap screws. One of these screws is eas­ily accessible; the other can only be reached
by disassembling the brake caliper. Do this
and remove the cap screws to remove the
brake pads.

5. Remove the brake rotor and have it profes­sionally resurfaced. For this, find a local
machinist or auto supply store that regularly
resurfaces brake rotors for automobiles. If
visible cracks are present in the brake rotor,
replace it with a new one. Remove oil and
dirt from the rotor with automotive brake
cleaner. Once clean, only handle the rotor
with a dry rag and install exactly the reverse
of removal.

6. Install new brake pads, mount the caliper
and reconnect the air line.

Calibration

NOTICE

The digital thickness gauge has been cali­brated at the factory and should require no
further adjustment, however, we recom­mend verifying its accuracy.

The first board fed through the sander will be
used to test the accuracy of the digital thickness
gauge.

To calibrate the digital thickness scale:

1. Follow the start up procedures from
Section 5: Set Up beginning on page 12.

2. Using a properly set-up planer, plane a board

to uniform thickness.

3. Lower the sander table far enough to place
the planed board under the sander roller.

4. Manually raise the table until the board just
touches the sanding roller.

5. Remove the board without changing the
table height. This ensures the table will be
properly adjusted for the first sanding pass.

6. Run the board through the sander several
times at the initial height setting. Manually
raise the table 0.020" and pass the board
through the sander several more times.
Monitor the amperage meter and the result­ing load on the sander.

7. Using a precise micrometer or set of calipers,
measure the thickness at various points
around the board.

8. Continue sanding the board until the average
thickness measurement is within

+

⁄-0.003".

Note—The final several passes should be

done without adjusting the table height. This
ensures the most consistent average thick­ness.

9. Make note of the digital display read-out. It
should be the same as the average thickness
of the sanded wood.

— If they are the same, the sander is prop-

erly calibrated and accurate to the near­est 0.001". Continue to the next sub-sec­tion.

— If the digital display readout is not the

same, recalibration is needed. Continue
on to step 10.

10. Without moving the table height, enter the
numerical measurement of the average
thickness of the sanded wood into the digital
key pad on the control panel. Note—The

average thickness of the sanded wood
should now be flashing on the digital read­out.

11. Press and hold the SET key until the display
stops flashing. The sander is now correctly
calibrated.

DO NOT sand boards with the guard
removed. Failure to follow this warning
could result in serious personal injury.

To adjust the feed belt tension:

1. Disconnect the sander from the power
source!

2. Raise the safety guard (Figure 17) on the

front end of the feed table.

3. Increase or decrease the feed belt tension by
adjusting the bolts located on the left and
right side of the front table roller (Figure 17).
Note—When tensioned properly, you should

not be able to lift the feed belt off the table
surface or slide it back and forth.

NOTICE

Adjust the feed belt tension before adjusting
the feed belt tracking.

Feed Belt Tracking

To adjust the feed belt tracking:

1. Start the feed belt.

— If the feed belt is tracking to the right side

of the table, turn the right adjustment bolt
(Figure 22) clockwise.

— If the feed belt is tracking to the left side

of the table, turn the left adjustment bolt
(Figure 18) clockwise.

Note—The edge of the feed belt should just touch

the guide wheels as shown in Figure 18.

2. Run the feed belt for 3-5 minutes and verify
the tracking.

Belt Oscillation

NOTICE

The oscillation adjustments have been per­formed at the factory and should require no
further attention. However, we recommend
verifying the settings.

Figure 19. Improper oscillation.

Sanding Belt

Limit Switches

Sander Outline

(Top View)

When the oscillation is correctly adjusted, the
sanding belt oscillates to the left and to the right
at the same speed and without coming into con­tact with the limit switches. If the sanding belt
oscillates too far to the left or right, making con­tact with the limit switches as shown in Figure 19,
the emergency braking system will activate.

To check the sanding belt oscillation:

1. Be sure the sanding belt is properly installed

and the belt tension switch is set to tension
the belt.

2. With safety glasses on and the left access
door still open, press the SANDING BELT
START Button.

3. Watch as the belt either oscillates back and
forth continuously, or tracks into one of the
two limit switches, triggering the emergency
brake.

— If the belt tracks into either limit switch,

adjust the two air flow adjustment knobs
independently of one another until the the
belt no longer hits the limit switches. Trial
and error may be necessary.

— If the oscillation time is not consistent

from one direction to the other, the air
cylinder arm needs to be lengthened or
shortened according to the following
guidelines:

• If the belt tracks away from the air
cylinder faster, shorten the arm.

• If the belts tracks towards the air cylin­der faster, lengthen the arm. Note—A

small adjustment goes a long way.
Make many smaller adjustments rather
than one or two large adjustments.

— If the oscillation rate needs to be

increased or decreased, adjust the air
flow adjustment counter-clockwise in
small, equal amounts until the desired
speed is achieved. Note—A combination

of knob adjustments and air cylinder arm
length adjustments may be needed to
achieve the ideal oscillation timing and
speed. Trial and error adjustments may
be necessary.

Table Parallelism

NOTICE

The table has been adjusted at the factory
and should require no further attention.
However, we recommend verifying that it is
parallel with the sanding roller.

Table Mounting Bolts

Adjusting the table parallelism can be a very
tedious task that takes a great amount of patience.
DO NOT adjust the table unless you are having
trouble sanding your workpiece to a uniform
thickness. Take precise notes on any adjust­ments you make to any of the table elevation
screws (Figure 20). This will allow the original
setting to be re-established.

To adjust the table parallelism:

1. Pass an 18" wide board through the sander

until the entire surface of the board is mak­ing contact with the sanding belt.

2. Measure the thickness of the board at vari­ous points around the edge.

— If there is a variation of thickness, the

table can be adjusted accordingly.

3. Disconnect the sander from the power
source!

Elevation Screws

(Inside Dust Boots)

Figure 20. View of table underside.

5. To raise the elevation screws, turn them

counterclockwise. To lower them, turn them
clockwise. One quarter of a turn raises or
lowers the elevation screws approximately

0.020".

6. Retighten the table mounting bolts loosened
in step 4.

7. Connect the sander to the power source.

8. Repeat Steps 1-7 until the board is sanded

to a uniform thickness.

4. The corners of the table can be indepen­dently adjusted up or down by spinning the
table elevation screws (Figure 20) located
under each corner of the table. Note—The

table mounting bolts (Figure 29) need to be
removed first.

NOTICE

When adjusting the left front elevation
screw, make the same adjustment to the left
rear elevation screw. This ensures the height
from the front to the back of the table
remains unchanged. Do the same when
adjusting the right elevation screws.

Pressure Rollers

5. Disconnect the sander from the power
source!

6. Loosen the roller lock nuts (Figure 22) on the

infeed pressure roller.Turn the adjustment
bolts (Figure 22) to lower the pressure roller
until it just touches the board. Note—DO

NOT continue to lower the roller beyond that
point.

7. Tighten the roller lock nuts and recheck your
settings.

8. Connect the sander to the power source and
make note of the reading on the digital dis­play. Then manually lower the table an addi­tional 0.020" to 0.030". This is how much
lower the outfeed pressure roller should be
set when compared to the height of the
infeed roller.

9. Loosen the roller lock nuts on the outfeed
pressure roller.Turn the adjustment bolts to
lower the pressure roller until it just touches
the board. Note—DO NOT continue to lower

the roller beyond that point.

10. Tighten the roller lock nuts and recheck your
settings.

Note—Variables such as feed rate, depth of the

cut, and the type of sanding belt can play a big
part in determining the proper amount of down­ward pressure exerted by the rollers. Some
experimentation may be necessary to achieve
the desired results. However, under no circum­stances should the pressure rollers be set even
with, or higher than, the sanding roller.

To adjust the pressure rollers:

1. Disconnect the sander from the power
source!

2. Plane (2) 36" long 2x4’s to a uniform thick-

nesses. Place one board along the length of
the feed belt on the right-hand side and place
the other board on the left-hand side.

3. With the sanding belt tensioned (Figure 21),
grab the edge of the sanding belt and move
it up and down about an inch or so. At the
same time, manually raise the table until you
just hear the sandpaper make contact with
the surface of the wood. DO NOT continue to
raise the table beyond that point.

4. Connect the sander to the power source and
make note of the reading on the digital dis­play. Then manually lower the table 0.020" to

0.030". This is how much lower the infeed
pressure roller should be set when compared
to the sanding surface of the sanding roller.

There are two V-belts on the Model G0527—one
on the table lifting motor (

Figure 23

) and one on

the sanding drum motor (

Figure 24

).

NOTICE

The V-belts have been properly adjusted at
the factory and should require no further
attention. If future adjustment is needed fol­low the instructions below.

To adjust either V-belt:

1. Disconnect the sander from the power
source!

2. Loosen the lock nut (

).

3. Turn the adjustment nut up or down until the
proper V-belt tension is achieved. Note—The

V-belt should deflect 1" off of center when
pushed with your finger.

4. Retighten the lock nut.

Air System

If you ever determine that a component in
the air system is malfunctioning, DO NOT
operate the sander. Fix the problem before
resuming operation.

The air system is durable and reliable; however,
components do wear with age. If you suspect that
an item in your air system may be having prob­lems, see the air line circuit on the next page.

Periodically inspect the following:

• Carefully inspect all air lines for leaks.
Replace faulty hoses.

• Check the air connections for leaks. A small
amount of soapy water in a questionable
area will bubble if there is a leak.

• Make sure the lines are not clogged.
Remove questionable lines and blow through
them as a test.
