at least once a week. To minimize the risk of eye injury, always wear
ANSI Z87.1 approved eye protection when performing this.
WARNING: Never use solvents or other harsh chemicals for
cleaning the non-metallic parts of the tool. These chemicals may
weaken the plastic materials used in these parts. Use a cloth
dampened only with water and mild soap. Never let any liquid get
inside the tool; never immerse any part of the tool into a liquid.

2. Drill straight, keeping the bit at a right angle to the work. Do not
exert side pressure on the bit when drilling as this will cause
clogging of the bit flutes and a slower drilling speed.
3. When drilling deep holes, if the hammer speed starts to drop off,
pull the bit partially out of the hole with the tool still running to help
clear debris from the hole.
4. For masonry, use carbide-tipped bits or masonry bits. A smooth
even flow of dust indicates the proper drilling rate.
Chipping and Chiselling (Fig. 1)
1. Set the mode selector switch (G) to the hammering only position.
2. Insert the appropriate chisel and rotate it by hand to lock it.
3. Adjust the side handle (C) as required.
4. Be sure chisel is in contact with work surface before depressing
the trigger switch.
5. Always fully release the trigger switch when work is finished and
before unplugging.
MAINTENANCE
WARNING: To reduce the risk of injury, turn unit off
and disconnect it from power source before installing and
removing accessories, before adjusting or when making
repairs. An accidental start-up can cause injury.
Motor Brushes
DEWALT uses an advanced brush system which automatically stops
the drill when the brushes wear out. This prevents serious damage
to the motor. New brush assemblies are available at authorized
D
EWALT service centers. Always use identical replacement parts.
