Features
Anti-vibration Side Handle
DWE4369
The anti-vibration side handle offers added comfort by
absorbing the vibrations caused by the tool.
No-Volt
The No-volt function stops the grinder restarting without the
switch being cycled if there is a break in the power supply.
E-Clutch
This unit is equipped with an E-Clutch (Electronic Clutch), which
in the event of a stall 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.
Brake
When the slider switch is released the motor immediately turns
off and electronically brakes stopping the accessory quickly.
8
Kickback Brake™
When a severe 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 off and then
on) to restart tool.
Constant Clutch™
When overloaded or stalled the motor torque is reduced. If load
is reduced the torque and RPM will increase. If the tool is stalled
for an extended amount of time it will shut-off and require the
switch to cycle to restart.
Electronic Soft Start
This feature limits the initial start up momentum, allowing the
speed to build up gradually over a 1 second period.
LED Indicator (Fig. A)
The LED indicator 10 will remain lit green during normal
activity, or blink in a pattern of red light to alert you a tool
protection feature has been activated. Refer to the LED Guide at
the back of this manual for explanations of blink patterns.
ASSEMBLY AND ADJUSTMENTS

WARNING: To reduce the risk of serious personal
injury, turn tool off and disconnect tool from power
source before making any adjustments or removing/
installing attachments or accessories. Be sure the
trigger switch is in the OFF position. An accidental start-up
can cause injury.
Attaching Side Handle (Fig. B)

WARNING: Before using the tool, check that the handle is
tightened securely.
Screw the side handle 3 tightly into one of the holes on either
side of the gear case. The side handle should always be used to
maintain control of the tool at all times.
Guards

CAUTION: Guards must be used with all grinding
wheels, cutting wheels, sanding flap discs, wire
brushes, and wire wheels. Refer to Figure A to see
guards provided with the unit. Some applications may
require purchasing the correct guard from your local
dealer or authorized service centre.
nOTE: Edge grinding and cutting can be performed with Type
27 wheels designed and specified for this purpose; 6 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 guard must be used for any wheel where
surface grinding is forbidden. Cutting can also be performed by
using a Type 41 wheel and a Type 1 guard.
nOTE: See the Grinding and Cutting Accessory Chart to select
the proper guard / accessory combination.
