Before use

It is essential that the safety precautions printed in these
operating instructions are read and observed.
en
Fitting the side handle
1.Unplug the tool from the mains socket.
2. Release the side handle clamping band by turning
the handle in a counter-clockwise direction.
3. Fit the side handle clamping band over the chuck
and onto the cylindrical section at the front end of
the tool.
4. Pivot the side handle into the desired position.
5. Tighten the side handle securely to prevent inad-
vertent movement.
Check that the side handle is seated securely.
The supply voltage must correspond to the information
on the type plate.
If extension cords are used: Only extension cords of a
type approved for the intended use and of adequate cross
section may be used. Failure to observe this point may
result in reduced performance of the tool and overheating
of the cord. Damaged extension cords must be replaced.
Use only insert tools with TE-C connection end.
Don't exert excessive pressure on the tool. This will not
increase its hammering power.
At low temperatures: The tool requires to reach a mini-
mum operating temperature before the hammering mech-
anism begins to operate. Switch on the tool and position
the tip of the drill bit on the work surface. While the tool
is running, apply light pressure briefly and repeatedly
until the hammering mechanism begins to operate.

Operation

CAUTION: In the event of the drill bit sticking, the tool
will pivot about its own axis.
Always use the tool with the side handle fitted and hold
it securely with both hands applying an opposing torque
16
so that the clutch releases in the event of the drill bit
sticking.
Use a vice or clamp to secure loose workpieces.
Fitting the insert tool
1. Unplug the supply cord from the mains socket.
2. Check that the connection end of the insert tool is
clean and lightly greased. Clean it and grease it if nec-
essary.
3. Check that the sealing lip of the dust shield is clean
and in good condition. Clean the dust shield if nec-
essary or replace it if the sealing lip is damaged.
4. Push the connection end of the insert tool into the
chuck and, while applying slight pressure, rotate the
insert tool 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 (pull
by hand).
Removing the insert tool
-CAUTION-
– The insert tool may become hot during use. There is
a risk of burning the hands. Wear protective gloves
when changing insert tools.
1. Unplug the supply cord from the mains socket.
2. Open the chuck by pulling back the locking sleeve.
3. Pull the insert tool out of the chuck.

Drilling

Hammer drilling (TE 2 / TE 2-E / TE 2-S / TE 2-M) /
precision hammering action (TE 2-S)
1. Insert the drill bit into the chuck.
2. Turn the function selection switch to the hammer
drilling position ( ) until the gearing is engaged
.

Rotate the chuck spindle slightly if necessary. Check
that forwards rotation is selected
3. Use of the precision hammering action (
tageous when drilling in brittle materials (e.g. tiles,
marble, perforated brick). This will improve the qual-
ity of the holes drilled
4. Connect the supply cord to the power supply.
5. Pivot the side handle, with or without the depth gauge,
to the desired angle and tighten the handle to lock it
in this position. Check that the side handle is seated
and attached securely
6. Bring the tip of the drill bit into contact with the work
surface at the position where the hole is to be drilled
and press the control switch slowly. Drill at low speed
until the drill bit centres itself in the hole.
7. Press the control switch fully and continue drilling at
full power.
