firmly to maintain control of the tool at start up and
during use and until the wheel or accessory stops
rotating. Make sure the wheel has come to a complete
stop be fore laying the tool down.
nOTE: To reduce unexpected tool movement, do not
switch the tool on or off while under load conditions. Allow
the grinder to run up to full speed before touching the work
surface. Lift the tool from the surface before turning the tool
off. Allow the tool to stop rotating before putting it down.

tool to the work surface.
2. Apply minimum pressure to the work surface, allowing
the tool to operate at high speed. Material removal rate
is greatest when the tool operates at high speed.
3. Maintain an appropriate angle between the tool
and work surface. Refer to the chart according to
particular function.

4. Maintain contact between the edge of the wheel and
the work surface.
- If grinding, sanding with flap discs or wire brushing
move the tool continuously in a forward and
back motion to avoid creating gouges in the
work surface.
If sanding with a backing pad, move the tool
-
constantly in a straight line to prevent burning and
swirling of work surface.
nOTE: Allowing the tool to rest on the work surface without
moving will damage the work piece.
5. Remove the tool from work surface before turning tool
off. Allow the tool to stop rotating before laying it down.
