en
CAUTION
Wear protective gloves when changing insert tools as the
insert tool will get hot during use.
1. Disconnect the supply cord plug from the power
outlet.
2. Open the chuck by pulling back the chuck release
sleeve.
3. Pull the insert tool out of the chuck.

outlet.
2. Pull the chuck sleeve forward and hold it securely.
3. Remove the chuck by pulling it away from the power
tool.
7.1.5 Fitting the chuck 7
CAUTION
Remove the depth gauge from the side handle and the
insert tool from the chuck in order to avoid injury.
1. Disconnect the supply cord plug from the power
outlet.
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.
8
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 Drilling without hammering 8
1. 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.
2. Bring the side handle into the desired position and
check that it is fitted correctly and secured.
3. Plug the supply cord into the power outlet.
4. Position the power tool and drill bit at the point
where the hole is to be drilled.
5. Press the control switch slowly (drill at a low speed
until the drill bit centers itself in the hole).
6. Press the control switch fully to continue drilling with
full power.
7. 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.
7.2.3 Hammer drilling 8
1. 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.
2. Bring the side handle into the desired position and
check that it is fitted correctly and secured.
3. Plug the supply cord into the power outlet.
4. Position the power tool and drill bit at the point
where the hole is to be drilled.
5. Press the control switch slowly (drill at a low speed
until the drill bit centers itself in the hole).
6. Press the control switch fully to continue drilling with
full power.
7. Do not apply excessive pressure. This will not in-
crease the power tool's hammering performance.
Lower pressure extends the life of the insert tool.
8. Reduce drilling speed shortly before breaking
through in order to avoid spalling.
7.2.4 Forward / reverse 9
CAUTION
Do not operate the forward / reverse switch while the
motor is running.
Move the forward/reverse switch to the "Forward" or
"Reverse" position.
