USING CUTTING WHEELS
1. Allow tool to reach full speed before touching tool to work sur-
face.
2. Apply minimum pressure to work surface, allowing tool to oper-
ate at high speed.
3. Once you begin a cut, maintain the angle of the cutting wheel to
the work surface. This will keep you from bending the wheel
which could result in wheel breakage and injury.
4. Remove the tool from work surface before turning tool off. Allow
the tool to stop rotating before setting it down.
MAINTENANCE
Cleaning
Blowing dust and grit out of the motor housing using clean, dry
compressed air is a necessary regular maintenance procedure.
Dust and grit containing metal particles often accumulate on interior
surfaces and could create an electrical shock hazard if not fre-
quently cleaned out. ALWAYS WEAR SAFETY GLASSES.
CAUTION: Never use solvents or other harsh chemicals for
cleaning the non-metallic parts of the tool. Use a clean, dry rag only.
