power outage or other unexpected shut down, the switch needs to
be cycled (turned off and on) to restart tool.
CLUTCH (D28140, D28144, D28144N)
The torque limiting clutch reduces the maximum reaction torque
transmitted to the operator in case of jamming a cutting disc. This
feature also prevents the gearing and electric motor from stalling. The
torque limiting clutch has been factory set and cannot be adjusted.
E-CLUTCH
TM
This unit is equipped with an E-Clutch
TM

using the tool, check that the handle is tightened
securely. Use a wrench to firmly tighten the side
handle.
Rotating
the Gear
Case
1. Remove guard and flanges from tool.
2. Remove the four corner screws attaching the gear case to motor
housing.
3. Separating the gear case from motor housing not more than 1/4"
(6.35 mm), rotate the gear case head to desired position.
NOTE: If the gear case and motor housing become separated
by more than 1/4" (6.35 mm), the tool must be serviced and
re-assembled by a DEWALTservice center. Failure to have the tool
serviced may cause brush, motor and bearing failure.
4. Re-install screws to attach the gear case to the motor housing.
Tighten screws to 18 in./Ibs. (2.03 Nm) torque. Overtightening
could cause screws to strip.
5. Re-install
guard
and
correct
flanges
for the
appropriate
accessories.
