Troubleshooting; Troubleshootung - Craftsman 137.215360 Owner's Manual

For your own safety, turn switch OFF and remove plug
from the power source outlet before maintaining, or
lubricating your belt / disc sander.
1. Frequently blow out or vacuum out any dust that may
accumulate inside the motor.
2. Remove impacted sawdust from the disc and belt
abrasive or replace abrasive.
Certain cleaning agents and solvents damage plastic
parts. Some of these are: gasoline, carbon tetrachioride,
chlorinated cleaning solvents, ammonia and household
detergents that contain ammonia. Avoiding use of these
and other types of cleaning agents, minimizes the
probability of damage.
To avoid shock or fire hazard, if the power cord is worn or
cut or damaged in any way, have it replaced immediately.
All repairs, electrical or mechanical, should be attempted
only by trained repairmen. Contact the nearest Sears
Service Center.
