MAINTENANCE
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 problems, see the Air
System Diagram on Page 48
for troubleshooting locations.
Verify or set the following:
• Adjust regulator to 75 PSI.
• Carefully inspect all air lines for cracks, pinches, 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
malfunctioning, bleed all air from the
system, and
fix the problem before
you resume
sanding.
Dust and Water Traps
Three collection traps on this wide-belt sander need to
be emptied when they become half full. One water trap
is attached to the bottom of the air regulator, and two
dust traps are attached on the air diaphragm assemblies.
DO NOT allow the water trap and dust bowls to become
full.
Dust Traps: To empty the dust trap bowls, TURN OFF AIR
PRESSURE, allow air pressure to bleed out, then unscrew
and empty the bowls (Figure
29).
Water Trap: With the system under air pressure, push the
lower drain valve and empty the water trap (Figure 29).
Also, replace the internal white moisture filters yearly.
