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.
CAUTION
During operation, wear protective gloves, especially
when inserting, adjusting and removing the insert
tool, because the insert tool can become hot during
use.
7.1 Preparing for use
7.1.1 Fitting the insert tool
5
CAUTION
Do not use drill bits with a C-type connection end in
a drill adapter. After inserting drill bits in the adapter,
check for firm seating and concentricity.
1. Set the forward / reverse switch to the middle posi-
tion or remove the battery from the power tool.
2. Check that the connection end of the insert tool is
clean and lightly greased. Clean it and grease it if
necessary.
NOTE
Make sure that not too much grease is ap-
plied.
3. Check that the sealing lip of the dust shield is clean
and in good condition. Clean the dust shield if nec-
essary or replace it if the sealing lip is found to
be damaged (please refer to the “Care and mainte-
nance” 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 into the chuck until it is heard to
engage.
6. After insertion, check that the drill bit is held securely
in the chuck and turns concentrically.
7.1.2 Adjusting the depth gauge / side grip
6
CAUTION
Use only depth gauges not exceeding 180 mm (7") in
length.
DANGER
Check that the side handle is correctly secured in
place.
An insufficiently secured side handle may cause
personal injury.
1. Release the side grip clamping band by turning the
grip counterclockwise.
2. Pivot the side grip into the desired position.
3. Adjust the depth gauge to the desired drilling depth.
4. Tighten the side grip securely by turning the grip
section. This also clamps the depth gauge in posi-
tion.
7.1.3 Removing the tool
7
1. Set the forward / reverse switch to the middle posi-
tion or remove the battery from the power tool.
2. Open the chuck by pulling back the chuck release
sleeve.
3. Pull the insert tool out of the chuck.
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.
Expo-
sure 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 briefly into contact with the base material
while allowing 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.
7.2.2 Forward / reverse
NOTE
The forward / reverse switch is used to select the direction
of rotation of the drive spindle. An interlock prevents
switching while the motor is running. The control switch
is locked when the forward / reverse switch is in the
middle position.
For forward rotation, push the forward / reverse switch
on the side of the power tool toward the chuck in the
direction of the arrow.
