4.1 Pneumatic connection
The pneumatic connection is to be made by quali-
fied personnel with extensive knowledge in han-
dling of pneumatic systems.
Screw provided coupling (1) onto the hand grip. Plug compressed air hose into cou-
pling. 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 Insertion of studs
Without feeding unit: fill the feeding pipe (11) with approx. 10 studs (flange leading).
With feeding unit: connect the gun with the feeding hose of the studs until feeding
pipe (11) 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 (20) into one of the moistened tyre holes. Operate the trigger
(24) and keep it pressed. The stud is pressed into the tire. Release trigger (3); 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.

pressed air connection

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.
5.3 Conversion of machine gun to manual gun
If you are using a studding machine (AS-ZN, EP-ZN or EPK-ZN) and want to disman-
tle the gun from the base frame to use it manually you’ll firstly have to convert the
gun, i.e. to release the trigger:
Disconnect the gun from the compressed air supply.
Release trigger: Slip off O-ring (26) from bushing (28) and dowel pin (25) appears.
The dowel pin can be easily pushed out of the bore. The trigger (26) is now released
and can be removed. Turn the trigger by 90° and insert it back into the bushing. Then
insert the dowel pin into the bore of the bushing. Slip the O-ring over and place it into
the groove.
The gun must be set back to its initial state should you want to use it
on the studding machine.

take the trigger (24). Clean and lubricate
trigger slightly with oil.
Check if compression spring (3) broken, if so
replace compression spring.
6.4
Worn spreader fingers (20)
Unscrew union nut (16) and take the head
(22) off the gun. Remove O-Ring (18) and
replace spreader finger (20)
6.5
Worn push rod (10)
Unscrew union nut (16) and take the head
(22) off the gun. Unscrew both hexagon
socket head cap screws (23) (Caution!) and
press intermediate piece (15) against trigger
(pressure of inner springs). Remove inter-
mediate piece and circlip (13). Extract push
rod (10) together with the springs (8, 9),
retaining ring (12) piston disk (6) and lip seal
(7). Unscrew hexagon nut (4) and replace
worn push rod. Assemble the gun in re-
versed order and replace hexagon nut if
necessary.
6.6
Worn separating finger (20)
Unscrew union nut (16) and take the head
(22) off the gun. Remove O-ring (18). Drive
