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.

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.
If you operate this machine on any circuit that is
already close to its capacity, it might blow a fuse
or trip a circuit breaker. However, if an unusual
load does not exist and a power failure still
occurs, contact a qualified electrician or our
Service Department at (570) 546-9663.

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
machine, we do not recommend the use of extension cords. Instead, position your equipment near
installed wiring to eliminate the need for extension cords.

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
portion of the manual before attempting any type
of operation.

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.
