INSPECTION, MAINTENANCE, AND CLEANING
1. WARNING! Make sure the Power Switch (part #39) of the Angle Grinder 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 Angle Grinder. Check
for loose screws, misalignment or binding of moving parts, cracked or broken
Grinding Wheel, damaged electrical wiring, 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. PERIODICALLY, the two Carbon Brushes (part #41) should be checked. If the
Carbon Brushes are simply dirty, they may be cleaned by rubbing them with a
pencil eraser. If the Carbon Brushes are excessively worn, they must both be
replaced at the same time. To clean or replace the Carbon Brushes, unscrew
and remove the Brush Caps (part #42) to expose the Carbon Brushes. Pull out
both Carbon Brushes from their Brush Holders (part #40), and insert two new
Carbon Brushes in the Brush Holders. Then, replace the Brush Caps.
(See Figure D.)
5. To operate the Angle Grinder, plug the Power Cord (part #50) into a grounded,
120 volt, electrical outlet.
6. Grip the Angle Grinder firmly with
both hands. Then turn the Power Switch
(part #39) to its “ON” position and allow the Grinding Wheel to rotate to its fullest
speed. (See Figure D.)
7. Do not force the rotating Grinding Wheel into the object being ground. Apply
moderate pressure, allowing the Grinding Wheel to rotate freely without being
forced.
8. After the grinding job is completed, turn the Power Switch (part #39) to its “OFF”
position. Then unplug the Power Cord (part #50) from its electrical outlet.
4. Use only a clean cloth and mild detergent to clean the body of the
Angle Grinder. Do not use solvents. Do not immerse any part of the tool in
liquid.
