INTENDED USE

These heavy-duty rotary hammers have been

designed for professional drilling and hammerdrilling,

screwdriving and light chipping

DO NOT use under wet conditions or in presence of

flammable liquids or gases.

These hammerdrills are professional power tools.

DO NOT let children come into contact with the

tool. Supervision is required when inexperienced

operators use this tool.

Torque Limiting Clutch

All rotary hammerdrills are equipped with a torque

limiting clutch that reduces the maximum torque

reaction transmitted to the operator in case of

jamming of a drill bit. This feature also prevents the

gearing and electric motor from stalling. The torque

limiting clutch has been factory-set and cannot be

adjusted.

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 charger 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.

If the supply cord is damaged, it must be replaced

by a specially prepared cord available through the

DEWALT service organization.

Mains Plug Replacement

(U.K. & Ireland Only)

If a new mains plug needs to be fitted:

• Safely dispose of the old plug.

• Connect the brown lead to the live terminal in

the plug.

• Connect the blue lead to the neutral terminal.

WARNING: No connection is to be

made to the earth terminal.

Follow the fitting instructions supplied with good

quality plugs. Recommended fuse: 3 A.

Using an Extension Cable

If an extension cable is required, use an approved

3–core extension cable suitable for the power

input of this tool (see technical data).The minimum

conductor size is 1.5 mm

; the maximum length is

30 m.

When using a cable reel, always unwind the cable

completely.

ASSEMBLY AND ADJUSTMENTS

WARNING: To reduce the risk of

injury, turn unit off and disconnect

machine from power source before

ups or when making repairs. Be sure

the trigger switch is in the OFF position.
