Instructions for use
• Always observe the safety instructions
and applicable regulations.
• Be aware of the location of pipework
and wiring.
• Apply only a gentle pressure to the tool.
Excessive force does not speed up
drilling but decreases tool performance
and may shorten tool life.
Prior to operation:
• Insert the appropriate bit.
• Mark the spot where the hole is to be drilled.
Switching on and off (fig. A)
• To run the tool, press the variable speed switch (1).
The pressure exerted on the variable speed switch
determines the tool speed.
• If necessary, press the lock-on button (2) for
continuous operation and release the switch.
The lock-on button works only in full speed,
forward rotation.
Chuck removal (fig. B)
• Open the chuck jaws as far as possible.
Always wait until the motor has come to
a complete standstill before changing the
direction of rotation.
• Insert a screwdriver into the chuck and remove
the chuck retaining screw (8) by turning
clockwise.
• Tighten an Allen key into the chuck and strike it
with a hammer as shown.
Maintenance
Your DEWALT Power Tool has been designed to
operate over a long period of time with a minimum
of maintenance. Continuous satisfactory operation
depends upon proper tool care and regular cleaning.
Lubrication
Your power tool requires no additional lubrication.
Cleaning
Keep the ventilation slots clear and regularly clean
the housing with a soft cloth.
Unwanted tools and the environment
Take your tool to an authorized DEWALT repair
agent where it will be disposed of in an
environmentally safe way.
Inserting and removing a bit (fig. A)
Keyed chuck
• Open the chuck by turning the sleeve (6)
counterclockwise and insert the bit shank.
• Put the chuck key (7) into each hole in the side
of the chuck and turn clockwise until tight.
• To remove the bit, proceed in reverse order.
Forward/reverse slider (fig. A)
• To select forward or reverse rotation, use the
forward/reverse-switch (3) (see arrow on tool).

• To stop the tool in continuous operation, press
the switch briefly and release it. Always switch off
the tool when work is finished and before
