situations where the wheel or accessory may
be at risk to bind. The electronics prevents
further rotation of the drive spindle by switching
the power tool off (it does not prevent
kickback). To resume operation, turn on/off
switch to the off position, then restart tool.
Constant Response Circuitry:
Helps maintain near constant RPMs between
no-load and load conditions.
Soft Start:
Helps reduce stress on the motor that occurs
from a high torque start. Helps bring accessory
smoothly up to speed.
Automatic Restart Protection:
Helps prevent accidental startups after power
has been interrupted, e.g. the tool was
unplugged with the switch locked in the on
Lock Nut & Backing Flange
Your tool is equipped with a threaded spindle
for mounting non-threaded hub accessories.
Always use the supplied backing flange with
a lock nut. Inner flange is keyed to output
shaft (Fig. 3). Always ensure that arbor
diameter matches accessory diameter.
Accessories that run eccentrically may burst.
Installing Side Handle
The side handle is used to control and
balance the tool. Securely thread handle into
either side of gear housing, depending on
personal preference, comfort, operation
being performed. The handle should always
be installed onto the guard protected side of
the tool (Fig. 4). Use the side handle for safe
control and ease of operation.
Hand Shield
The hand shield is to be used with backing
pads, sanding discs and wire brushes to
keep fingers and hand away from work
surface, sharp edges, burrs and debris.

switch to the off position, then restart the tool.
See the chart under Fig. 1 and Fig. 2 to find
out which grinders are equipped with the
Automatic Restart Protection.
Overload Protection:
Helps protect tool from excessive heat that
may damage motor. If tool stops or slows
during operation, allow motor to cool for 30
seconds by running no-load. If the overload
protection stops the tool repeatedly, excessive
force is causing the tool to overload. Stop
excessive force and readjust work piece to
reduce force applied.
Variable Speed:
Allows the grinders RPM to be adjusted for
greater versatility to match needs of specific
applications.
