EN
Screw provided screw coupling (2) into the handle. Plug compressed air hose in-
to the screw coupling. The gun requires compressed air with approx. 7-8 bar
working pressure. The maximum operating pressure amounts to 10 bar.
5 Operation of the gun
5.1 Elimination of studs
Press the gun with the claws (36) into the tire rubber over a stud. Operate the trigger
(7) and keep it pressed. The claws close and seize the stud. Then the gun is pushed
off the tire with the push-off plate (25) and the stud is pulled out of the tire. Release
the trigger as soon as the stud has been fully pulled out of the tire. The push-off plate
returns, the claws open, the extracted stud is set free and can be disposed of.
Do not hold the gun with the hand in the area of the push-off
plate. There is danger of violent pressure!
When impressing the gun above the stud a certain counter
pressure has to be put by hand to the tire rubber. With some
practice and skill you will soon find out the correct pressure
in order to obtain a steady working result.

6 Faults and trouble shooting
No.
Cause
Trouble shooting
6.1
Wear of the claws (36)
Take off O-Ring (37), remove spring dowel pin (34)
and shafts (33). Take out claws (36), turn by 180° and
reinsert with the unused side showing to the front.
Take care that the balls (35) will be reinserted.
If both sides of the claws are worn new claws will have
to be installed.
6.2
The push-off movement of the
push-off plate (25) is too much in
advance of the closing move-
ment of the claws (36).
Screw off gun head (28), remove piston disks (12, 19)
with the expanding mandrel (17). Check possible dam-
ages of the grooved rings (16); if o.k. clean and
grease. If the grooved rings are damaged or worn re-
place by new ones.
Check if the pressure springs (24) are broken; replace
broken pressure springs.
Check function and tightness of leaf springs (13, 15),
replace defective leaf springs.
6.3
Trigger (7) gets caught
Remove O-Ring (10) and dowel pin (11), take out trig-
ger (7), clean and slightly
lubricate with oil.
Check if pressure spring (6) is broken, if so replace
pressure spring.
