8. Care and maintenance

Disconnect the supply cord plug from the socket.
8.1 Care of core bits
Remove any dirt adhering to the core bits and protect
their surfaces from corrosion by rubbing them with an
oily cloth from time to time. Always keep the connec-
tion end clean and slightly greased.
8.2 Care of the tool
Check that the supply cord plug is disconnected.
-CAUTION-
Keep the power tool, especially its grip surfaces, clean
and free from oil and grease. Do not use cleaning agents
which contain silicone.
Never operate the tool if its ventilation slots are blocked.
Clean the ventilation slots carefully with a dry brush.
Do not allow foreign objects to enter the interior of the
tool.
Clean the outside surfaces of the tool with a damp cloth
at regular intervals. Do not use a spray, steam clean-
ing equipment or running water for cleaning. This could
negatively affect the electrical safety of the tool. Always
keep the grip surfaces of the tool free from oil and
grease. Do not use cleaning agents which contain sil-
icone.
Clean the chuck and the clamping segments with a
cloth at regular intervals and lubricate these parts with
Hilti lubricant spray. Remove any dirt and fragments
from the chuck.
Remove the filter in the water intake at the side handle
from time to time and rinse the filter sieve under run-
ning water in the direction opposite to the normal water
flow.
If the water flow indicator has become dirty, remove
and clean the parts. Do not use abrasive agents or sharp
objects to clean the sight glass. This may negatively
affect functionality of the water flow indicator.

8.3 Maintenance of the tool

Check all external parts of the tool for damage at regu-
lar intervals and check that all operating controls func-
tion faultlessly. Do not operate the tool when parts are
damaged or when operating controls do not function
faultlessly. The tool should be repaired at a Hilti service
centre.
Repairs to the electrical section of the tool may be car-
ried out by trained electrical specialists only.
8.4 Care of the drill stand
8.4.1 Care of the chain
Check the chain guides to ensure they remain clean and
free from drilling slurry. The chain must always be pro-
tected by a film of grease.

8.5 Maintenance of the drill stand
8.5.1 Adjusting the movement
Movement should be easy but without play.
The movement can be adjusted by way of screws (2 at
the top and 2 at the bottom).
8.5.1.1 Stiffer movement
1. Release the lower screw.
2. Tighten the upper screw as far as necessary.
3. Tighten the lower screw as far as it will go.
8.5.1.2 Easier movement
1. Release the upper screw.
2. Tighten the lower screw as far as it will go.
8.5.2 Adjusting the chain tension
When the carriage is in the end position, the chain should
sag only slightly when running horizontally. Chain ten-
sion can be adjusted by way of two screws (chain sym-
bol on the cover).
G Turning in a clockwise direction increases chain ten-
sion.
G Turning in a counter-clockwise direction decreases
chain tension.
Both chains must be tensioned equally.
