7 Operation

CAUTION
In the event of the drill bit sticking, the power tool will
pivot about its own axis. Always use the power tool with
the side handle fitted and hold it securely with both hands
so that the resulting opposing force causes the slip clutch
to release in the event of the drill bit sticking. Use clamps
or a vice to hold the workpiece securely.

7.1 Preparing for use

7.1.1 Adjusting the depth gauge 3
1. Release the side handle clamping band by turning
the handle counterclockwise.
2. Pivot the side handle into the desired position.
3. Adjust the depth gauge to the desired drilling depth.
4. Tighten the side handle securely by turning the
grip section. This also clamps the depth gauge in
position.
7.1.2 Fitting the insert tool 4
CAUTION
Wear protective gloves when changing the insert tool.
1. Disconnect the supply cord plug from the power
outlet.
2. Check that the connection end of the insert tool is
clean and lightly greased. Clean it and grease it if
necessary.
3. Check that the sealing lip of the dust shield is clean
and in good condition. Clean the dust shield if ne-
cessary or replace it if the sealing lip is found to be
damaged (please refer to the "Care and mainten-
ance" section).
4. Push the insert tool into the chuck and rotate it while
applying slight pressure until it engages in the guide
grooves.
5. Push the insert tool further into the chuck until it is
heard to engage.
6. Check that the insert tool has engaged correctly by
pulling it.
7.1.3 Removing the insert tool 5
CAUTION
Wear protective gloves when changing insert tools as the
insert tool will get hot during use.

7.2 Operation
CAUTION
Working on the material may cause it to splinter. Wear
eye protection and protective gloves. Wear breathing
protection if no dust removal system is used. Splin-
tering material presents a risk of injury to the eyes and
body.
CAUTION
The work generates noise. Wear ear protectors. Expos-
ure to noise can cause hearing loss.
7.2.1 Working at low temperatures
NOTE
The hammering mechanism works only when the power
tool has reached a minimum operating temperature.
Bring the drill bit into contact with the base material
and allow the power tool to run under no load until the
minimum operating temperature is reached. If necessary,
repeat this procedure until the hammering mechanism
begins to operate.
Disconnect the supply cord plug from the power
outlet.
Open the chuck by pulling back the chuck release
sleeve.
Pull the insert tool out of the chuck.
Disconnect the supply cord plug from the power
outlet.
Pull the chuck sleeve forward and hold it securely.
Remove the chuck by pulling it away from the power
tool.
Disconnect the supply cord plug from the power
outlet.
Grip the chuck sleeve, pull it forward and hold it
securely in this position.
Slide the chuck onto the guide tube from the front
and then release the sleeve.
Rotate the chuck until it is heard to engage.
