Maintenance
Before doing maintenance
on the sander, disconnect it from the
electrical supply by pulling out the plug or
switching off the main switch! Failure to
comply may cause serious injury.
Make periodic or regular inspections to ensure
that your sander is properly adjusted, that all
screws are tight, the belt is in good condition,
that dust has not collected in the motor or
electrical enclosures and there are no loose or
worn electrical fittings or wiring.
If the power cord is worn, cut, or damaged in
any way, have it replaced immediately.
Keep the fence and table surfaces clean and
free of rust.
Lubrication
Periodically lubricate the following parts on the
31A Sander.
Use a good quality, non-hardening grease on:
•
Idler slide (Figure 25)
•
table trunnion (shown in Figure 9)
Use SAE No. 10 Oil on these:
•
internal threads of table locking wheels (A,
Figure 14)
•
belt arm index pin (shown in Figure 3)
All bearings used on the Model 31A Sander are
sealed for life and require no lubrication.
