3. Remove the chuck by pulling it away from the power
tool.
7.1.5 Fitting the chuck 9
CAUTION
Remove the depth gauge from the side handle and the
insert tool from the chuck in order to avoid injury.
1. Set the forward / reverse switch to the middle posi-
tion or remove the battery from the power tool.
2. Grip the chuck sleeve, pull it forward and hold it
securely in this position.
3. Slide the chuck onto the guide tube from the front
and then release the sleeve.
4. Rotate the chuck until it is heard to engage.
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 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.
For reverse rotation, push the forward / reverse switch on
the side of the power tool toward the grip in the direction
of the arrow.
Bring the forward / reverse switch into the desired posi-
tion.
7.2.3 Drilling without hammering 10
1. Set the forward / reverse switch to the "forward"
position before beginning drilling.
2. Turn the function selector switch until it engages in
the "Drilling without hammering" position. Do not
operate the function selector switch while the motor
is running.
3. Bring the side handle into the desired position and
check that it is fitted correctly and secured.
4. Fit the battery.
5. Position the power tool and drill bit at the point
where the hole is to be drilled.
6. Press the control switch slowly (drill at a low speed
until the drill bit centers itself in the hole).
7. Press the control switch fully to continue drilling with
full power.
8. Adjust the pressure applied to the power tool ac-
cording to the material you are working on. This will
ensure the optimum rate of drilling progress.
7.2.4 Hammer drilling 11
1. Set the forward / reverse switch to the "forward"
position before beginning drilling.
2. Turn the function selector switch until it engages in
the "Hammer drilling" position. Do not operate the
function selector switch while the motor is running.
3. Bring the side handle into the desired position and
check that it is fitted correctly and secured.
4. Fit the battery.
5. Position the power tool and drill bit at the point
where the hole is to be drilled.
6. Press the control switch slowly (drill at a low speed
until the drill bit centers itself in the hole).
7. Press the control switch fully to continue drilling with
full power.
8. Adjust the pressure applied to the power tool ac-
cording to the material you are working on. This will
ensure the optimum rate of drilling progress.
9. Reduce drilling speed shortly before breaking
through in order to avoid spalling.
7.2.5 Reading the charge state LED display on
Li‑ion batteries 12
NOTE
The charge state cannot be indicated while the power
tool is in operation. Indication is given (LED 1 blinks)
when the battery is fully discharged or when it is too hot.
The battery must then be inserted in the charger. If all 4
LEDs blink, this indicates that the power tool has been
overloaded or has overheated.
