7 Operation

DANGER
en
Always hold the power tool securely with both hands
on the grips provided. Keep the grips dry, clean and
free from oil and grease.
7.1 Preparing for use
CAUTION
Wear protective gloves when changing insert tools
as the insert tools get hot through use and they may
have sharp edges.
7.1.1 Fitting the insert tool 4
NOTE
The chisel can be adjusted to 6 different positions (in 60°
increments). This ensures that flat chisels and shaped
chisels can always be set to the optimum working posi-
tion.
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 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 further into the chuck until it is
heard to engage.
6. Check that the insert tool has engaged correctly by
pulling it.
7.1.2 Removing the chisel 5
DANGER
Do not lay a hot insert tool down on flammable ma-
terials. This could cause the material to ignite, resulting
in a fire.
1. Disconnect the supply cord plug from the power
outlet.
2. Open the chuck by pulling back the locking sleeve.
3. Pull the chisel out of the chuck.

7.2 Operation
WARNING
If the power tool starts without pressing the on/off
switch when the supply cord is plugged back in after
unplugging, the power tool must be brought to Hilti
Service immediately.
WARNING
Unplug the supply cord if the on/off switch is found
to be faulty.
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 Chiseling
7.2.1.1 Working at low temperatures
NOTE
The power tool must reach a minimum operating tem-
perature before the hammering mechanism begins to
operate.
Bring the power tool to the minimum operating temperat-
ure by switching it on and allowing it to run and warm up.
Bring the tip of the chisel into contact with the work sur-
face at regular intervals (approx. every 30 sec.) to check
whether the hammering mechanism has begun to oper-
ate. Repeat the procedure if the hammering mechanism
does not begin to operate.
NOTE
As starting is electronically controlled, the power tool's
starting characteristics may be different in cold condi-
tions.
7.2.1.2 Switching on
1. Plug the supply cord into the power outlet.
2. Press the on / off switch.
