OPERATION
Instructions for Use
WARNING:
Always observe the safety instructions and
applicable regulations.
WARNING: To reduce the risk of serious personal
injury, turn tool off and disconnect tool from power
source before making any adjustments or removing/
installing attachments or accessories.
Be sure the
trigger switch is in the OFF position. An accidental start-up
can cause injury.
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 (Fig. G). Always operate the
tool with the side handle properly mounted.
Proper Hand Position (Fig. G)
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
8
,
with the other hand on the main handle
2
.
Switching On and Off (Fig. A)
1. To run the tool, press the variable speed switch
1
. The
pressure exerted on the variable speed switch determines
the tool speed.
2. For continuous operation, press and hold down the variable
speed switch.
3. To stop the tool, release the switch.
Hammerdrilling (Fig. A)
Drilling with a Solid Bit
1. Hold down the mode selector button
5
then set the mode
selector switch
4
to the hammerdrilling position.
2. Insert the appropriate drill bit.
nOTE:
For best results use high quality carbide-tipped bits.
3. Adjust the side handle
8
as required.
4. If necessary, set the drilling depth.
5. Mark the spot where the hole is to be drilled.
6. Place the drill bit on the spot and switch on the tool.
7. Always switch off the tool when work is finished and
before unplugging.
Drilling with a Core Bit
1. Hold down the mode selector button
5
then set the mode
selector switch
4
to the hammerdrilling position.
2. Adjust the side handle
8
as required.
3. Insert the appropriate core bit.
4. Assemble the centerdrill into the core bit.
5. Place the centerdrill on the spot and press the on/off
switch
1
. Drill until the core penetrates into the concrete
approx. 1 cm.
6. Stop drilling and remove the centerdrill. Place the core bit
back into the hole and continue drilling.
7. When drilling through a structure thicker than the depth of
the core bit, break away the round cylinder of concrete or
core inside the bit at regular intervals. To avoid unwanted
breaking away of concrete around the hole, first drill a hole
the diameter of the center drill completely through the
structure. Then drill the cored hole halfway from each side.
8. Always switch off the tool when work is finished and
before unplugging.
Rotary Drilling (Fig. A)
1. Hold down the mode selector button
5
then set the mode
selector switch
4
to the “rotary drilling” position.
2. Fit the chuck adapter/chuck assembly.
3. Proceed as described for hammerdrilling.
WARNING:
Never use standard chucks in the
hammerdrilling mode.
Screwdriving (Fig. A)
1. Hold down the mode selector button
5
then set the mode
selector switch
4
to the rotary drilling position.
2. Select the direction of rotation.
3. Insert the special SDS Plus screwdriving adaptor for use with
hexagonal screwdriver bits.
4. Insert the appropriate screwdriver bit. When driving slotted
head screws always use bits with a finder sleeve.
5. Gently press the variable speed switch
1
to prevent
damage to the screw head. In reverse (LH) rotation the tool
speed is automatically reduced for easy screw removal.
6. When the screw is flush with the workpiece, release the
variable speed switch to prevent the screw head from
penetrating into the workpiece.
Chipping and Chiselling (Fig. A)
1. Hold down the mode selector button
5
then set the mode
selector switch
4
to the “hammering only” position.
2. Insert the appropriate chisel and rotate it by hand to lock it
