Operation - Hilti TE 4-A22 Operating Instructions Manual

4. Slide the side handle clamping band over the chuck
and onto the shaft.
5. Pivot the side handle into the desired position.

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 Fitting the insert tool 5
CAUTION
Wear protective gloves when changing the insert tool.
1. Set the forward / reverse switch to the middle posi-
tion or remove the battery from the power tool.
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 ne-
cessary or replace it if the sealing lip is found to be
damaged (please refer to the "Care and mainten-
ance" 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 into the chuck until it is heard to
engage.
6. Check that the insert tool has engaged correctly by
pulling it.
7.1.2 Adjusting the depth gauge / side handle 6
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.
7.1.3 Removing the insert tool 7
CAUTION
Wear protective gloves when changing insert tools as the
insert tool will get hot during use.
1. Set the forward / reverse switch to the middle posi-
tion or remove the battery from the power tool.
6. Fit the depth gauge and secure the side handle in
the desired position by turning the grip firmly until
tight.
2. Open the chuck by pulling back the chuck release
sleeve.
3. Pull the insert tool out of the chuck.
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.
CAUTION
The work generates noise. Wear ear protectors. Expos-
ure 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 Forward / reverse
NOTE
The forward / reverse switch is used to select the direction
of rotation of the drive spindle. An interlock prevents
switching while the motor is running. The control switch
is locked when the forward / reverse switch is in the
middle position.
For forward rotation, push the forward / reverse switch
on the side of the power tool toward the chuck in the
direction of the arrow.
For reverse rotation, push the forward / reverse switch on
the side of the power tool toward the grip in the direction
of the arrow.
Bring the forward / reverse switch into the desired posi-
tion.
