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.
Tip!
Use only less dish liquid to avoid that the inserted
stud is pulled out again when extracting the gun.
Insert spreader fingers (23) into one of the moistened tyre holes. Operate the
trigger (28) and keep it pressed. The stud is pressed into the tire. Release trig-
ger (28); the gun is now loosen from the tire and the stud is inserted.
Tip!
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.

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
dismantle the gun from the base frame to use it manually you’ll firstly have to
convert the gun, i.e. to release the trigger:
Caution!
Disconnect the gun from the compressed air sup-
ply.

pears. The dowel pin can be easily pushed out of the bore. The trigger (28) is
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.

6.2 Remove feeding tube and shake out stud
Remove O-Ring (30) and dowel pin (29) and
then trigger (28). Clean and lubricate trigger
slightly with oil.
Check if compression spring (3) broken, if so
replace compression spring.
6.3 Trigger (28) get caught
Unscrew Union nut (18) and take the head
(26) off the gun. Remove spring lock (21)
and replace spreader finger (23)
6.4 Worn spreader fingers (23)
Unscrew Union nut (18) and take the head
(26) off the gun. Unscrew both hexagon
head cap screws (27) (Caution!), hold the
intermediate piece (17) (pressure of inner
springs). Remove intermediate part and
circlip (15). Extract push rod (12) together
with the springs (10, 11), retaining ring (14)
piston disk (6) and lip seal (7). Unscrew
hexagon nut (4) and replace worn push rod.
Assemble the gun is reversed order and
