children) suffering from diminished physical, sensory or
mental abilities; lack of experience, knowledge or skills
unless they are supervised by aperson responsible for their
safety. Children should never be left alone with thisproduct.
Dust Ejection System
The dust ejection system deflects debris that would be harmful
to the motor and allows cleaner air to pass over the motor.
Overload Protection
DWE4579, DWE4579R, DWE4597,
DWE4599
The power supply to the motor will be reduced in case of motor
overload. The power will return to normal once the tool has
cooled down to suitable operating temperature.
Electronic Clutch
DWE4579, DWE4579R, DWE4597,
DWE4599
The electronic torque limiting clutch reduces the maximum
torque reaction transmitted to the operator in case of jamming
of adisc. This feature also prevents the gearing and electric
motor from stalling. The level of the electronic clutch has been
factory set and cannot be adjusted.
LED Indicator (Fig.A)
DWE4579, DWE4579R, DWE4597,
DWE4599
The LED indicator light
6
, mounted at the top of the handle,
acts as an alert to the activation of the electronic features of
the unit described above. The light will activate and maintain
aconstant light when one of the above clutch or overload
features is activated. Once the unit has been reset by releasing
the switch or allowing the unit to cool the light will de-activate.
If the LED light is flashing constantly please consult your local
D
EWALT service agent.
No-volt Release Switch
DWE4579, DWE4579R, DWE4597,
DWE4599
The on/off switch has ano-volt release function. If the tool
should become disconnected from the power source for any
reason, the switch has to be deliberately reactivated.
Soft Start Feature
DWE4579, DWE4579R, DWE4597,
DWE4599
The soft start feature allows aslow speed build-up to avoid an
initial jerk when starting. This feature is particularly useful when
working in confined spaces.
