1.BEFORE EACH USE, inspect the general condition of the tool. Check for:

loose hardware,

misalignment or binding of moving parts,

cracked or broken parts,

damaged electrical wiring, and

any other condition that may affect its safe operation.

2.After Use, wipe external surfaces of the tool with clean cloth.

3.Periodically blow dust and grit out of the motor vents using dry compressed air. Wear ANSI‑approved safety goggles and NIOSH‑approved

breathing protection while doing this.

4.Periodically recheck all nuts, bolts, and screws for tightness.

7.Use only a clean cloth and mild detergent to clean the body of the Polisher. Do not use solvents.
