Operating functions

ΠSwitch with electronic speed control
Screwdriving speed can be adjusted
smoothly up to maximum r.p.m. by slow-
ly pressing the control switch.
 Reversing switch
The reversing switch is used to reverse the
direction of rotation of the chuck. A lock-
ing device prevents operation of the switch
while the motor is running. The control
switch Πis deactivated when the re-
versing switch is in the central position.
Ž 2-speed switch
The speed range can be selected by ad-
justing the 2-speed switch.(1st speed: 0–
320 r.p.m. or 2nd speed: 0–1150 r.p.m.)
This switch should be operated only when
rotation has stopped.
 Torque clutch adjustment ring
The release torque (1 Nm to 10 Nm) is ad-
justed by rotating the adjustment ring to
the desired torque setting (positions 1–
10). The torque clutch is deactivated when
the ring is set to the drill bit symbol. With
the ring set to this position, the screwdriver
provides a max. torque of approx. 20 Nm
(blocking torque).
 Motor brake
The motor brake reduces the time taken
for the chuck to stop rotating. This per-
mits, for example, screws to be driven to
an even depth for optimum appearance.
‘ Battery release button (2-finger
operation)
To remove ther battery, press the battery
release buttons and pull the SB12 bat-
tery out of the screwdriver.
’ Quick-release chuck (1.5–13 mm)
The insert tool can be inserted or removed
Printed: 07.07.2013 | Doc-Nr: PUB / 5070506 / 000 / 00
without the use of a chuck key. A locking
device prevents rotation of the motor spin-
dle when the control switch is in the OFF
position. This feature is of assistance when
tightening or opening the chuck.

Care and maintenance

The gearing section has been filled with
sufficient grease during assembly. The
screwdriver thus requires no maintenance.
If used heavily over a long period of time,
it is recommended that the screwdriver is
returned to Hilti for inspection.This can ex-
tend the life of the screwdriver and avoid
unnecessary repair costs. The air intake/exit
slots should be kept clean. If an excessive
amount of dust collects, clean the screw-
driver by blowing out dust with a jet of com-
pessed air.
Electric tools must comply with the appli-
cable safety regulations. Servicing may
only be carried out by a recognised elec-
trical specialist. Optimum safety can be
ensured by using only original Hilti spare
parts.
