the end of their life must be disposed of safely and
correctly to avoid environmental pollution.
6.2 Charging the battery
DANGER
Use only the Hilti batteries and Hilti chargers listed
under “Accessories”.
6.2.1 Charging a new battery for the first time
Charge the battery fully before using it for the first
time.
6.2.2 Charging a previously used battery
Ensure that the outer surfaces of the battery are
clean and dry before inserting it in the corresponding
charger.
Read the operating instructions for the charger for
further information about the charging procedure.
Li-ion batteries are ready for use at any time, even
when only partly charged. Charging progress is in-
dicated by the LED display (see charger operating
instructions).
6.3 Fitting the battery
CAUTION
Before fitting the battery, check that the power tool
is switched off and that the safety lock is engaged
(forward/reverse switch in the middle position). Use
only the Hilti batteries approved for use with this
power tool.
CAUTION
Check that the terminals on the battery and in the
power tool are free from foreign objects before
inserting the battery in the power tool.
1.
Push the battery into the power tool from the
rear as far as it will go and until it is heard to
engage with a double click.
2.
CAUTION A falling battery may present a risk
of injury to yourself or others.
Check that the battery is seated securely in the
power tool.
6.4 Removing the battery
2
1.
Press one or both release buttons.
2.
Pull the battery out of the power tool toward the
rear.
6.5 Transport and storage of battery packs
Pull the battery pack out of the locked position (work-
ing position) and move it into the first latching position
(transport position).
If you disconnect a battery pack from the power tool
for transport or storage, make sure that the contacts
of the battery pack are not short-circuited. Remove
loose metal parts such as screws, nails, clamps,
loose screw bits, wires or metal swarf from the case,
toolbox or transport container, or prevent these parts
from coming into contact with the battery packs.
Observe national and international transport regula-
tions when shipping battery packs (transportation by
road, rail, sea or air).
6.6 Belt hook
3
CAUTION
Check that the belt hook is fitted securely before
beginning work.
The belt hook allows the power tool to be attached to
a belt worn by the operator. The belt hook can also
be fitted to the other side of the power tool for use by
left-handed persons.
1.
Pull the battery out of the tool.
2.
Fit the mounting plate into the guides provided.
3.
Secure the belt hook with the two screws.
7. Operation
CAUTION
The tool may get hot during use.
Wear protective
gloves.
CAUTION
When drilling and screwdriving, the grip of the tool
may be deflected laterally (the tool tends to pivot
about its own axis).
CAUTION
To avoid injuries caused by the insert tool, wear
protective gloves when changing insert tools.
7.1 Setting forward or reverse rotation
4
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. Push the forward /
reverse switch to the right (power tool held in working
direction) to select forward rotation. Push the forward
/ reverse switch to the left (power tool held in working
direction) to select reverse rotation.
7.2 Speed selection using the 2-speed gear
switch
5
NOTE
The mechanical 2-speed gear switch can be used to
select the speed range required. Speed with fully-
charged battery: SFC 14
ತ

7.3 Switching on / off
Speed of rotation can be controlled smoothly up
to maximum speed by pressing the control switch
slowly.
7.4 Fitting the drill bit
1.
Set the forward / reverse switch to the middle
position or remove the battery from the power
tool.
2.
Check that the connection end of the drill bit is
clean. Clean the connection end if necessary.
3.
Insert the drill bit in the keyless chuck and then
turn the chuck firmly by hand until several clicks
are heard.
4.
Check that the drill bit is held securely.
7.5 Removing the drill bit
1.
Set the forward / reverse switch to the middle
position or remove the battery from the power
tool.
2.
Open the keyless chuck.
3.
Pull the insert tool out of the chuck.
7.6 Drilling
CAUTION
Use clamps or a vice to secure the workpiece. The
workpiece is thus held more securely than by hand
and both hands remain free to operate the power
tool.
1.
Turn the torque and operating mode setting ring
to the drilling symbol.
2.
Move the forward / reverse switch to the “For-
ward” position.
7.7 Screwdriving
7.7.1 Fitting the bit holder / bit
1.
Set the forward / reverse switch to the middle
position or remove the battery from the power
tool.
2.
Open the quick-release chuck.
3.
