Screw provided coupling (1) onto the hand grip. Plug compressed air hose into
coupling. The gun requires compressed air with approx. 7-8 bar working pres-
sure. The maximum operating pressure amounts to 10 bar.
5 Operation of the gun
5.1 Insertion of studs
Without feeding unit: fill the feeding pipe (13) with approx. 10 studs (flange leading).
With feeding unit: connect the gun with the feeding hose of the studs until feeding
pipe (13) is filled with studs (flange leading).
Moisten tire with low surface tension water. To get this, mix normal tap water with
some drops of usual dish liquid.
Use only less dish liquid to avoid that the inserted stud is pulled out
again when extracting the gun.
Insert spreader fingers (34) into one of the moistened tyre holes. Operate the trigger
(17) and keep it pressed. The stud is pressed into the tire. Release trigger; the gun is
now loosen from the tire and the stud is inserted.
Put some pressure onto the gun when inserting the studs. With some
practice and skill you’ll soon find the respective pressure which shall
be applied to reach a steady result.
5.2 Faults during insertion
5.2.1 Studs inserted to deep
Reduce the pressure applied on the gun during insertion.
5.2.2 Studs jut out off the tire
Put more pressure onto the gun when inserting the studs.

replace compression spring.
6.4
Worn spreader fingers (34)
Unscrew union nut (33) and take the head
(25) off the gun. Remove O-Ring (31) and
replace spreader finger (34)
6.5
Worn push rod (22)
Unscrew union nut (33) and take the head
(25) off the gun. Unscrew both hexagon
head cap screws (16) (Caution!), press
intermediate piece (21) against hand grip
(back-pressure of inner springs). Remove
intermediate part and circlip (15). Extract
push rod (22) together with the springs (10,
11), retaining ring (14) piston disk (6) lip seal
(7) and bushing (23). Unscrew hexagon nut
(8) and replace worn push rod. Assemble
the gun in reversed order and replace hexa-
gon nut if necessary.
6.6
Worn centring finger (32)
Unscrew union nut (33) and take the head
(25) off the gun. Remove O-Ring (31) and
replace centring finger (32).
6.7
Worn separating pin (27)
Unscrew union nut (33) and take the head
(25) off the gun. Remove separating flap
(26) from dowel pin (29). The compression
spring (28) may not jump out. The separat-
ing pin (27) is riveted with the separating flap
