3. FITTING ACCESSORIES
Make sure that the machine is disconnected from
the power supply when fitting accessories.
FITTING THE INSERT TOOLS ON
Fig. 2
The impact car wrench is supplied in a case with four
sockets and an extension piece. The sockets can simply
be pushed on to the square head of the impact car
wrench.
If necessary the extension piece can be used also (e.g for
nuts that are difficult to reach).
FUSE
Fig. 3
There is a 15A fuse in the cigarette lighter plug. The fuse
safeguards the user, the machine and the wiring.
Replacing the fuse:
• Take the plug out of the 12V connection.
• Turn loose the ribbed ring on the end of the plug.
• Remove the ribbed ring and the contact point.
• Take the fuse out of the plug and replace it with a new
one having the same safety value (15A).
N.B.: never replace the fuse with a higher value
one! This could result in damage to the machine
and danger of fire!
4. OPERATING
Before use
The power for the machine can be supplied in two ways
using the wiring supplied. Either the 12V connection in
the car (cigarette lighter) or a 12V battery can be used as
source of power.
Never use a power supply with a higher voltage
(> 12 V).
1. 12V cigarette lighter connection
The machine is fitted with a cable (about 4 m) with a plug
(4) at the end, which fits in the cigarette lighter plug in the
car.
2. 12V battery
The adapter supplied (7) has two connecting clamps (red
and black) and a connector for the plug of the impact car
wrench.
• Connect the plug on the impact car wrench to the
adapter cable.
• First connect the black clamp to the negative (-)
battery terminal.
• Then connect the red clamp to the positive (+)
battery terminal.
USING
• Use the on/off switch (1) to switch the machine on or
off.
• Set the direction of rotation of the output shaft with
switch (2).
The electric motor turns a weight in the head of the
machine. After a few seconds the output shaft will be
given a hefty impact from the weight because of the
centrifugal force, which will tighten or loosen the wheel
nut step by step.
LOOSENING A WHEEL NUT
• Turn the rotation direction switch (2) to position R
(Release).
• Put the machine on the wheel nut using the right
socket.
• Switch on the machine with the on/off switch and
hold the machine tightly.
• You will hear the electric motor rotating and after a
few seconds the machine will give the nut a hefty
anticlockwise impact. This will be repeated until the
nut is loose.
• Release the on/off switch to switch off the machine.
TIGHTENING A WHEEL NUT
• Tighten the wheel nut as far as possible by hand. The
machine works best when the nut experiences
sufficient resistance.
• Turn the rotation direction switch (2) to position F
(Fasten).
• Switch on the machine with the on/off switch and
hold the machine tightly.
• You will hear the electric motor rotating and after a
few seconds the machine will give the nut a hefty
clockwise impact. This will be repeated until the nut
is tight.
• Release the on/off switch to switch off the machine.
• N.B.: always check that wheel nuts are tight
afterwards using a torque wrench.
LED LIGHTING
When the on/off switch is operated the white LED
lighting will also be switched on. This keeps the wheel
nut visible even when it is dark.
