CAUTION: Hold the side handle and body of the tool
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.
1. To turn the tool on, push the lock-off lever
2

The spindle lock
3
is provided to prevent the spindle from
rotating when installing or removing wheels. Operate the
spindle lock only when the tool is turned off, unplugged from
the power supply, and has come to a completestop.

Surface Grinding, Sanding and Wire
Brushing

CAUTION: Always use the correct guard per the
instructions in thismanual.
To perform work on a the surface of a workpiece:
1. Allow the tool to reach full speed before touching the 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.
Function Angle
Grinding 20˚-30˚
Sanding with Flap Disc 5˚-10˚
Sanding with Backing Pad 5˚-15˚
Wire Brushing 5˚-10˚
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.

CAUTION: Use extra care when working over an edge, as
a sudden sharp movement of grinder may beexperienced.
