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.

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.

8 Care and maintenance

CAUTION
Disconnect the mains plug from the 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
CAUTION
Keep the power tool, especially its grip surfaces,
clean and free from oil and grease. Do not use clean-
ing agents which contain silicone.
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.
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.
8.3 Cleaning or replacing the dust shield
Clean the dust shield on the chuck with a dry, clean
cloth at regular intervals. Clean the sealing lip by wiping it
carefully and then grease it again lightly with Hilti grease.
It is essential that the dust shield is replaced if the sealing
lip is found to be damaged. Push the tip of a screwdriver
under the edge of the dust shield and prise it out toward
the front. Clean the area of the chuck in contact with dust
shield and then fit a new dust shield. Press it in firmly
until it engages.
8.4 Maintenance
WARNING
Repairs to the electrical section of the power tool may
be carried out only by trained electrical specialists.
Check all external parts of the power tool for damage
at regular intervals and check that all controls operate
faultlessly. Do not operate the power tool if parts are
damaged or when the controls do not function faultlessly.
If necessary, the power tool should be repaired by Hilti
Service.
8.5 Checking the power tool after care and
maintenance
After carrying out care and maintenance work on the
power tool, check that all protective and safety devices
are fitted and that they function faultlessly.
