USING CUTTING WHEELS
WARNING: Do not use edge grinding/
cutting wheels for surface grinding applica-
tions 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 operate at
high speed. Cutting rate is greatest
when the tool operates at high speed.
3. Once a cut is begun and a notch is established in the work-
piece, do not change the angle of the cut. Changing the angle
will cause the wheel to bend and may cause wheel breakage.
4. Remove the tool from work surface before turning tool off. Allow
the tool to stop rotating before setting it down.
MAINTENANCE
Cleaning
WARNING: Blowing dust and grit out of motor and switch actuator
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 or electrocu-
tion if not frequently cleaned out. It is recommended that a ground
fault circuit interrupter (GFCI) is utilized to further protect the user
from electric shock resulting from the accumulation of conductive
particles. If the tool is deactivated by the GFCI, unplug the tool and
check and clean the tool before resetting the GFCI. ALWAYS WEAR
SAFETY GLASSES when cleaning or using this tool.
CAUTION: Never use solvents or other harsh chemicals
for cleaning the non-metallic parts of the tool. Use a clean, dry
cloth only.
