Circuit Breaker Requirements
Install the machine on a dedicated circuit to
reduce the possibility of overloading the circuit
and tripping the circuit breaker.
If the circuit breaker trips and the circuit is of the
correct load capacity, have the circuit inspected
by qualified electrician. Never use a larger circuit
breaker than stated below, or you will increase
the risk of fire.
Always check to see if the wires in your circuit
are capable of handling the amperage draw from
your machine, as well as any other machines that
could be operating on the same circuit. If you are
unsure, consult a qualified electrician.
L15-30

Site ConsiderationsClean Up
The arbor shafts are coated with a wax or oil to
prevent rusting during shipment. Clean all coated
parts with a solvent cleaner or citrus-based
degreaser such as Grizzly’s G7895 Degreaser.
Avoid chlorine-based solvents as they may dam
age painted surfaces should they come in con
tact.
Gasoline and petroleum
products have low flash
points and could explode
if used to clean machin
ery. 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.
-
Weight Load
The Model G0530 weighs approximately 275 lbs.
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 with
out 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.
Lighting and Outlets
Lighting should be bright enough to eliminate
shadow and prevent eye strain. Electrical circuits
should be dedicated or large enough to handle
the amperage draw. Outlets should be located
near each machine so power or extension cords
are clear of high-traffic areas. Observe local elec
trical codes for proper installation of new lighting,
outlets, or circuits.
-
-
Lack of ventilation while
using solvents could
cause serious person
al health risks, fire, or
environmental hazards.
Always work in a well
ventilated area to pre
vent the accumulation
of dangerous fumes.
Supply the work area
with a constant source
of fresh air.
