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!
