6. Operation
6.1 Power supply
Connect the 12 V power plug (Fig. 1 Item 7) to the
vehicle's cigarette lighter socket.
6.2 Direction of rotation switch (Fig. 1/Item 3)
The slide switch above the On/Off switch is for
setting the direction of rotation of the impact
driver and for preventing the impact driver from
being switched on inadvertently. You can select
between counter-clockwise and clockwise rotati-
on. To avoid causing damage to the gearing, the
direction of rotation is allowed to be changed only
when the equipment is at a standstill. When the
slide switch is in the middle position, the On/Off
switch is blocked.
6.3 On/Off switch (Fig. 1/Item 4)
Switching on:
Press the On/Off switch (4).
Switching off :
Release the On/Off switch (4)
6.4 Working with the impact driver
Plug the required drive socket insert on the
square drive mount. Select the correct direction of
rotation on the impact driver.
Note:
•
The spirit level on the top of the driver (Fig. 1 /
Item 2) helps you to fit the drive socket insert
onto a wheel nut/wheel bolt in a straight posi-
tion.
•
The LED light (Fig. 1 / Item 5) will come on
when the equipment is connected to the 12 V
power supply. It enables the work area to be
illuminated when lighting conditions are poor.
6.4. 1 Tightening
Push the drive socket insert onto the screw head
and actuate the On/Off switch.
Carefully insert the bolt or nut in the thread before
you move the electric driver into position. A torque
of approx. 50 Nm per pulse is generated on stan-
dard bolts of size M12/M14. On motor cars, each
bolt should be tightened with two pulses. Each
bolt should then be checked with one additional
pulse. A total torque of approx. 150 Nm is thus
achieved.
GB
Three pulses are recommended on heavy vehic-
les (e.g. luxury cars, off -road vehicles, etc.). Each
bolt should then be tightened in diametrically
opposed order with one additional pulse. A total
torque of approx. 200 Nm is thus achieved.
Check the threaded connections for signs of da-
mage after tightening.
Danger!
Always check and retighten wheel nuts with
a torque wrench that is set to the torque spe-
cifi ed by the manufacturer of the vehicle in
question.
6.4.2 Slackening
To slacken a wheel bolt/wheel nut proceed as de-
scribed in the section "Tightening" but use the op-
posite direction of rotation. Several impact pulses
will be needed depending on how tight the wheel
nut/wheel bolt is seated.
7. Cleaning, maintenance and
ordering of spare parts
Danger!
Pull out the 12 V plug.
7.1 Cleaning
•
Keep all safety devices, air vents and the
motor housing free of dirt and dust as far as
possible. Wipe the equipment with a clean
cloth or blow it with compressed air at low
pressure.
•
We recommend that you clean the device
immediately each time you have finished
using it.
•
Clean the equipment regularly with a moist
cloth and some soft soap. Do not use
cleaning agents or solvents; these could at-
tack the plastic parts of the equipment. Ensu-
re that no water can seep into the device. The
ingress of water into an electric tool increases
the risk of an electric shock.
7.2 Maintenance
There are no parts inside the equipment which
require additional maintenance.
