Hilti TE 7 - Tool Operation and Preparation; Preparing the Tool for Operation; Fitting and Removing Insert Tools

7. Operation
CAUTION
In the event of the drill bit sticking, the power tool
will pivot about its own axis. Always use the power
tool with the side handle fitted and hold it securely
with both hands so that the resulting opposing force
causes the slip clutch to release in the event of the
drill bit sticking. Use clamps or a vice to hold the
workpiece securely.
7.1 Preparing for use
7.1.1 Adjusting the depth gauge 3
1. Release the side handle clamping band by turning
the handle counterclockwise.
2. Pivot the side handle into the desired position.
3. Adjust the depth gauge to the desired drilling
depth.
4. Tighten the side handle securely by turning the
grip section. This also clamps the depth gauge
in position.
7.1.2 Fitting the insert tool 4
CAUTION
Wear protective gloves when changing the insert tool.
1. Disconnect the supply cord plug from the power
outlet.
2. Check that the connection end of the insert tool
is clean and lightly greased. Clean it and grease
it if necessary.
3. Check that the sealing lip of the dust shield
is clean and in good condition. Clean the dust
shield if necessary or replace it if the sealing lip
is found to be damaged (please refer to the “Care
and maintenance” section).
4. Push the insert tool into the chuck and rotate it
while applying slight pressure until it engages in
the guide grooves.
5. Push the insert tool further into the chuck until it
is heard to engage.
6. Check that the insert tool has engaged correctly
by pulling it.
