Table Lift Screws: Should be cleaned with mineral spirits
and painted with lithium grease every six months. Then,
move the table up or down to spread the grease thor-
oughly over the threads. Do not overlubricate.
Worm Gear: Paint a light coat of lithium grease on the
worm gear threads (Figure 36) once a year.
Failure to routinely inspect your drum sander for
damage and wear could result in unsatisfactory work
results, premature component or machinery failure,
or operator injury. We recommend you create a
checklist for routine inspection and maintenance.
Remember to always disconnect the drum sander
from its power source before attempting to inspect,
adjust, or repair this machine!
