E-CLUTCH ANTI-LOCK CONTROL™ (FIG. 4)
DWD530, D21570
Your DEWALT drill may come with an electronic 
feature called E-CLUTCH Anti-Lock Control™. It is 
designed to help you control the drill during a stall 
and keep it from pulling out of your hands. This may 
be encountered when drilling in steel or using large 
bits in wood.
As a stall situation presents itself, the motor cycles 
on and off for a set period of time. This reduces 
the reaction of the stall and allows you to keep the 
drill under control. Releasing the trigger resets the 
E-Clutch and the unit will operate in normal mode 
when the trigger is depressed again.
The E-CLUTCH Anti-Lock Control™ also 
incorporates an overload protection feature designed 
to help prevent the unit from becoming too hot 
during high load applications. 
If the unit becomes excessively hot during operation 
this feature will cut the motor, The feature will 
continue to cut the motor if it is restarted and placed 
under a high load before it has cooled off.
Figure 4 shows the instruction label (n) mounted on 
the housing. There are two alert modes. 
 1. Engaged Mode: When a stall situation 
presents itself, the light will come on and stay 
on as the motor cycles on and off for a set 
period of time before the E-CLUTCH Anti-Lock 
Control™ completely shuts the tool down. 
When the unit is running in normal mode, there 
will be no light. 
 2. Problem Mode: A series of continual flashes 
as the trigger is pulled indicates that the 
electronics are no longer functioning. The tool 
may still be able to function without the benefit 
of E-CLUTCH Anti-Lock Control™ but should 
be serviced as soon as possible.
Electrical Safety
The electric motor has been designed for one 
voltage only. Always check that the power supply 
corresponds to the voltage on the rating plate.
 Your DEWALT tool is double insulated in 
accordance with EN 60745; therefore no 
earth wire is required.
   WARNING: 115 V units have to 
be operated via a fail-safe isolating 
transformer with an earth screen 
between the primary and secondary 
winding.
   This product is intended to be used with 
a safety transformer manufactured to 
BSEN61558 and BS4343. Never work 
without this transformer in place.
If the supply cord is damaged, it must be replaced 
by a specially prepared cord available through the 
DEWALT service organisation.

An accidental start-up can cause injury.
Side Handle (fi g. 2)
   WARNING: To reduce the risk of
