7. Adjust the pressure applied to the power tool
according 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 Chiseling
NOTE
The chisel can be adjusted to 18 different positions
(in 20° increments). This ensures that flat chisels and
shaped chisels can always be set to the optimum
working position.
7.2.4.1 Chisel position adjustment
CAUTION
Do not work operate the power tool when the selector
switch is set to “Chisel adjustment”.
1. Turn the function selector switch until it engages
in the “Chisel adjustment” position. Do not oper-
ate 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. Rotate the chisel to the desired position.
7.2.4.2 Locking the chisel
Turn the function selector switch until it engages in
the “Chiseling” position. Do not operate the function
selector switch while the motor is running.
7.2.4.3 Chiseling 8
1. Plug the supply cord into the power outlet.
NOTE Do not operate the function selector switch
while the motor is running.
2. Position the tip of the chisel at the point where
chiseling is to begin.
3. Press the control switch.
7.2.5 Forward / reverse 9

motor is running.
Move the forward/reverse switch to the “Forward” or
“Reverse” position.
8. Care and maintenance
CAUTION
Disconnect the supply cord plug from t he power
outlet.
8.1 Care of insert tools
Clean off dirt and dust deposits adhering to the insert
tools and protect them from corrosion by wiping the
insert tools from time to time with an oil-soaked rag.
8.2 Care of the power tool
The outer casing of the power tool is made from
impact-resistant plastic. Sections of the grip are made
from a synthetic rubber material.
Never operate the power tool when the ventilation
slots are blocked. Clean the ventilation slots carefully
using a dry brush. Do not permit foreign objects to
enter the interior of the power tool. Clean the outside
of the power tool at regular intervals with a slightly
damp cloth. Do not use a spray, steam pressure
cleaning equipment or running water for cleaning.
This may negatively affect the electrical safety of the
power tool. Always keep the grip surfaces of the
power tool free from oil and grease. Do not use
cleaning agents which contain silicone.
