reduce the reaction torque to the user. The switch needs to
be cycled (turned on and off) to restart tool.
Kickback Brake™
When a pinch, stall, or bind-up event is sensed the
electronic brake engages with maximum force to quickly
stop the wheel, reduce the movement of the grinder, and
shut the grinder off. The switch needs to be cycled (turned
on and off) to restart the tool.
Power-OFF™ OVERLOAD Protection
The power supply to the motor will be reduced in case
of motor overload. With continued motor overload, the
tool will shut off. The switch needs to be cycled (turned
on and off) to restart tool. The tool will power off each
time the current load reaches the overload current value
(motor burn-up point). If continued overload shutdowns
occur, apply less force/weight on the tool until the tool will
function without the overload engaging.
Electronic Soft Start
This feature limits the initial start up speed, allowing the tool
to build up to full speed gradually over a 1 second period.

ASSEMBLY AND ADJUSTMENTS


WARNING: To reduce the risk of serious personal
injury, turn unit off and remove the battery pack
before making any adjustments or removing/
installing attachments or accessories. An
accidental start-up can cause injury.

Rotating the Gear Case (Fig. E)
To improve user comfort, the gear case will rotate 90° for
cutting operations.
1. Remove the four corner screws attaching the gear case
to motor housing.
2. Without separating the gear case from motor housing,
rotate the gear case head to desired position.

90˚
NoTE: If the gear case and motor housing become
separated by more than 1/8" (3.17 mm), the tool must
be serviced and re-assembled by a D
center. Failure to have the tool serviced may motor and
bearing failure.
3. Reinstall screws to attach the gear case to the motor
housing. Tighten screws to 12.5 in.-lbs. torque.
Overtightening could cause screws to strip.
Guards

NoTE: Edge grinding and cutting can be performed with
Type 27 wheels designed and specified for this purpose;
1/4" (6.35 mm) thick wheels are designed for surface
grinding while thinner Type 27 wheels need to be examined
for the manufacturer's label to see if they can be used for
surface grinding or only edge grinding/cutting. A Type 1/41
guard must be used for any wheel where surface grinding
is forbidden. Cutting can also be performed by using a
Type 1/41 wheel and a Type 1/41 guard.
NoTE: See the Accessories Chart to select the proper guard
/ accessory combination.
