FEATURES
E-SWITCH PROTECTION™
The ON/OFF switch has a no-volt release function. In the event of a
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™
This unit is equipped with an E-Clutch™ (Electronic Clutch), which in
the event of a high-load or wheel pinch, the unit will shut off to reduce
the reaction torque to the user. The switch needs to be cycled (turned
off and on) 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 must be cycled (turned off and on) to restart tool. The power
will return to normal once the tool has cooled down to a suitable
operating temperature. NOTE: Run the tool at no load to reduce the
cool down time.
COMPLETE ELECTRONIC CONTROL™
The internal electronic speed control offers consistent wheel speed
while using the tool.
ASSEMBLY AND ADJUSTMENTS
WARNING: To reduce the risk of injury, turn unit off and
disconnect it from power source before installing and removing
accessories, before adjusting or when making repairs. Before
reconnecting the tool, depress and release the trigger switch
to ensure that the tool is off. An accidental start-up can cause
injury.
Attaching Side Handle (FIG. 2)
The side handle (E) can be fitted to either side of the
gear case in the threaded holes, as shown. Before
using the tool, check that the handle is tightened
se cure ly. 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 D
WALT service center. Failure to have the tool
E
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./lbs. (2.03 Nm) torque. Overtightening
could cause screws to strip.
5. Re-install guard and correct flanges for the appropriate
accessories.
