Assembly And Adjustments - DeWalt DWE402 Instruction Manual

These heavy-duty small angle grinders are professional power tools.
DO NOT let children come into contact with the tool. Supervision is
required when inexperienced operators use this tool.
E-SWITCH PROTECTION™
(DWE4222, DWE4222N, DWE4224)
The ON/OFF trigger switch has a no-volt release function. In the event
of a power outage or other unexpected shut down, the trigger switch
will need to be cycled (turned on and off) to restart tool.
E-CLUTCH™
(DWE4222, DWE4222N, DWE4224)
This unit is equipped with an E-Clutch™ (Electronic Clutch), which
in the event of a high-load or wheel pinch, the unit will be shut off to
reduce the reaction torque to the user. The switch needs to be cycled
(turned on and off) to restart tool.
POWER-OFF™ OVERLOAD PROTECTION
(DWE4222, DWE4222N, DWE4224)
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
(DWE4222, DWE4222N, DWE4224)
This feature limits the initial start up momentum, allowing the speed to
build up gradually over a 1 second period.

ASSEMBLY AND ADJUSTMENTS

WARNING: To reduce the risk of injury, turn unit off and
disconnect it from power source before making any adjustments
or removing/installing attachments or accessories. An accidental
start-up can cause injury.
Attaching Side Handle (Fig. 2)
The side handle (F) can be fitted to either side of the gear case in
the threaded holes. Before using the tool, check that the handle is
tightened se cure ly.
To improve user comfort, the gear case will rotate 90° for cutting
operations.
Rotating the Gear Case (Fig. 2)
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.
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 WALT service center.
e
Failure to have the tool serviced may cause
brush, motor and bearing failure.
3. Reinstall screws to attach the gear case to the motor housing.
Tighten screws to 20 in.-lbs. torque. Overtightening could cause
screws to strip.
