Sanding Belts; Air System - Grizzly H2933 Instruction Manual

Sanding Belts

You can greatly increase the lifespan of your
sanding belts if you clean them often. As men-
tioned on Page 26, cleaning pads are the fastest
way to remove saw dust build-up.

Air System

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 prob-
lems, see the Air System Diagram on Page 39.
• Adjust regulator to 75 PSI.
• Carefully inspect all air lines for cracks, tears
or hardening. 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 lines are not clogged. Remove
a questionable line and blow through it as a
test.
If a component in the air system is malfunc-
tioning, bleed all air from the system, and fix
the problem before you resume sanding.

Dust and Water
Traps
There are three traps on this wide belt sander.
One water trap is attached to the bottom of the
air regulator, and two dust traps are attached on
the air diaphragm assemblies. Cleaning is easy,
with the system under air pressure, you can push
the lower drain valve and empty regulator water
trap (Figure 21). Replace the internal white mois-
ture filters yearly. To empty the dust trap bowls,
relieve the air pressure and then unscrew and
empty the bowls (Figure 22). DO NOT allow the
water trap and dust bowls to become full.
