INSPECTION, MAINTENANCE, AND CLEANING
1. WARNING! Make sure the Power Switch (66) of the Belt Sander is in its
“OFF” position and that the tool is unplugged from its electrical outlet before
performing any inspection, maintenance, or cleaning procedures.
2. BEFORE EACH USE, inspect the general condition of the Belt Sander. Check
for loose screws, misalignment or binding of moving parts, damaged electrical
wiring, dull or damaged Sanding Belt (46), and any other condition that may
affect its safe operation. If abnormal noise or vibration occurs, have the problem
corrected before further use.
Do not use damaged equipment.
3. CARBON BRUSH: To maintain peak efficiency of the Belt Sander’s Motor it is
recommended that every two to six months the Carbon Brush (27) be examined.
The Carbon Brush should be free of dust and dirt. The Carbon Brush should be
replaced when it has worn down to 3/16” in length. The Carbon Brush should
slide freely in and out of the Brush Holder (25) without sticking. To check the
Carbon Brush, remove the Brush Holder Cover (28) located at the front of the
Belt Sander. Lift out the Carbon Brush to inspect. If cleaning is necessary, rub
the Carbon Brush thoroughly with a pencil eraser. Next, clean the Brush Holder
opening with compressed air or a clean cloth. Then, replace the Carbon Brush
and Brush Holder Cover.
(See Figure G.)
4. TO CLEAN: The ventilation openings should be kept clean and free of sawdust
and debris. The most effective way to clean the ventilation openings is with com-
pressed air. The outer body may be cleaned with a clean cloth and a mild deter-
gent. Do not use solvents. Do not immerse the Belt Sander in liquid.

8. Do not force the Belt Sander to remove material faster than it is designed to cut.
Push and pull the Sanding Belt (46)
gradually along the surface of the workpiece.
9. Once the sanding job is completed, turn off the Belt Sander and wait until the
Sanding Belt (46) stops turning. Then, unplug the Power Cord (14) from its
electrical outlet.
