USING CUTTING WHEELS
A WARNING: Do not use edge grinding/cutting wheels for surface
grinding applications because these wheels are not designed for
side pressures encountered with surface grinding. Wheel breakage
and injury may result.
1. Allow tool to reach full speed before touching tool to work
surface.
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
i_ WARNING: Blowing dust and grit out of the motor housing using
clean, dry compressed air is a necessary regular maintenance pro-
cedure. Dust and grit containing metal particles often accumulate on
interior surfaces and could create an electrical shock or electrocu-
tion if not frequently 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.
