G9983 15" Open-End Wide-Belt Sander -33-
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 prob-
lems, use the diagram on page 38 to follow all
lines and connections, and use the instructions
below to investigate.
• Carefully inspect all air lines for cracks, tears
or hardening. Replace faulty hoses.
• Check the air connections for leaks. A small
amount of 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.
Platen Graphite
The graphite sheet on the platen will wear out
with use. Similar to the sanding belts, the graphite
sheet is considered a “consumable” item and is
not covered under the warranty. We recommend
keeping replacements in your inventory to avoid
downtime. To obtain replacements, use the part
number in the back of this manual for ordering.
To replace the graphite sheet:
1. Pull the platen from its bracket with the
included platen puller tool.
2. Remove the screws and hold-down bar that
secure the graphite sheet to the platen.
3. Install the new graphite sheet exactly the
reverse as removal. Make sure that the
graphite sheet is wrapped in the same direc-
tion as the old one.
