cially if used frequently for working on conductive
materials. Dust (especially dust from conductive
materials) or dampness adhering to the surface of
the tool may, under unfavorable conditions, present
a risk of electric shock.

2.4 Work area

a) Ensure that the workplace is well lit.
b) Ensure that the workplace is well ventilated.
Poorly ventilated workplaces may be injurious to the
health due to exposeure to dust.

2.5 Personal protective equipment

The user and any other persons in the vicinity must
wear suitable eye protection, ear protection and pro-
tective gloves when the tool is in use.
Wear eye Wear ear
protection protection

2.6 Additional safety precautions

a) Carefully examine the nut setter socket/bit hold-
er/extension for wear, cracks or damage prior to use
or starting the tool at any time. Never touch the rotat-
ing nut setter socket/bit holder/extension.
b) Use protective gloves because the temperature of the
chuck, the socket wrench insert/bit holder/extension
and, under circumstances, the head of the screw just
driven or removed can be high after longer periods
of operation.
c) Hold the screwdriver securely when working with it.
Make sure you have a firm stance and always keep
your balance. Make sure that no-one is below you
when you are working with the screwdriver in a high
position.
d) Put the screw anchor into the socket wrench insert
only just before driving it in. Keep an eye open for
parts which might fall out during disassembly.
e) Don't hold or touch metal parts of the screw-
driver or bit / other insert tool when driving screws
into ceilings, walls and floors or other places which
might contain electric cables, conduits, etc. Hold only
the insulated grip surfaces of the screwdriver to avoid
an electric shock on unintentionally driving a screw
anchor / screw into an electric cable, etc.
f) Always make sure the rubber cover at the front of the
housing is properly fitted.
g) Only run the tool where it is to be used. In particular,
only switch it on after pointing it to where the fas-
tening is to be made.

Operating instructions

Selection of nut setter socket/bit holder/extension
Only use Hilti impact screwdriver nut setter sockets.
Use nut setter sockets with the same widths across flats
as the screws or nuts being driven. Widths across flats
not matching each other falsify the torque and damage
the nut setter insert and the screw head / nut.
Make sure that no foreign matter, such as small screws
or nails, are held by magnetic socket wrench inserts in
use when switching on the screwdriver.
Attachment of nut setter socket/bit holder/extension
Prior to attaching or removing the nut setter sock-
et/bit holder/extension, make sure the screwdriver is
switched off and its plug is pulled out of the electric sup-
ply socket (receptacle).
Remove the O-ring from the groove in the nut setter

socket and pull out the retaining pin. Put the nut setter

socket/bit holder/extension onto the square drive pin of
the screwdriver. Align the bores in the square drive pin
and nut setter/bit holder/extension to permit insertion
of the retaining pin. Insert the retaining pin and replace
the O-ring to secure the nut setter socket/bit holder/exten-
sion. Carry out these operations in the reverse order for
disassembly. The retaining pin for the nut setter sock-
et/bit holder/extension must be fitted and secured
before using the screwdriver.
Trigger switch
Prior to plugging the screwdriver into an electric
supply, always check that the trigger switch works prop-
erly and returns to the OFF position when released.
When switching on the screwdriver, press the electron-
ic trigger switch. The r.p.m. increase with greater pres-
sure on the switch. To switch off, release the switch.
Speed and torque presetting wheel
The speed, and thus also the torque, can be preselect-
ed by turning this wheel. The maximum speed and torque
are set when the screwdriver is delivered.
Reversing switch
The direction of rotation can be changed with the revers-
ing switch. Press the right-hand side of the switch for
clockwise rotation (F) and the left-hand side for counter-
clockwise rotation (R).
– Always check the direction of rotation before starting
to work.
– Never change the direction of rotation while the motor
is running. If you do, the screwdriver can be damaged.
Hold the screwdriver firmly and place the nut setter sock-
et over the screw head or nut. Drive in the screw or tight-
en the nut, while judging the time required.
