OPERATION
Instructions for Use
WARNING:
• 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 (approx. 5 kg). Excessive
force does not speed up drilling but
decreases tool performance and may
shorten tool life.
• Do not drill or drive too deep to
prevent damage to the dust cover.
• Always hold the tool firmly with both
hands and ensure a secure stance.
Always operate the tool with the side
handle properly mounted.
Proper Hand Position (fi g. 1, 8)
WARNING: To reduce the risk of
serious personal injury, ALWAYS use
proper hand position as shown.
WARNING: To reduce the risk of
serious personal injury, ALWAYS hold
securely in anticipation of a sudden
reaction.
Proper hand position requires one hand on the side
handle (i), with the other hand on the main
handle (q).
Switching On and Off (fig. 1)
1. To run the tool, press the variable speed switch
(a). The pressure exerted on the variable speed
switch determines the tool speed.
2. To stop the tool, release the switch.
3. To lock the tool in off position, move the
forward/reverse slider (b) to the central position.

Hammerdrilling (fig. 1)
DRILLING WITH A SOLID BIT
1. Set the mode selector switch (c) to the
hammerdrilling position.

Rotary Drilling (fig. 1)
1. Set the mode selector switch (c) to the "rotary
drilling" position.
2. Depending on your tool, follow either of the
following instructions:
– Fit a chuck adaptor/chuck assembly
(DC222/DC223). Special SDS Plus
adaptors with threaded sections are available
for use with standard 10 or 13 mm chucks
to enable straight shank bits to be used.
– Replace the tool holder with the chuck
(DC224).
3. Proceed as described for hammer drilling.
WARNING: Never use standard chucks
in the hammer drilling mode.
Screwdriving (fig. 1)
1. Set the mode selector switch (c) to the rotary
drilling position.
2. Select the direction of rotation.
3. Depending on your tool, follow either of the
following instructions:
- Insert the special SDS Plus
adaptor for use with hexagonal screwdriver
bits (DC222/DC223).
- Replace the tool holder with the chuck
(DC224).
4. Insert the appropriate screwdriver bit. When
driving slotted head screws always use bits with
a finder sleeve.
