3 Technical Data
3.1 Stud types
The gun can be used for the insertion of single-flange and multi-flange studs into car
tires. Factory setting is for the insertion of single-flange studs.
To operate the gun with multi-flange studs you’ll be needed to convert the gun (not
possible for EP-10). Exchange the separating finger (20) of the single-flange studs for
the provided separating fingers of the multi-flange studs, as described in chapter 6.7.

EN
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 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 (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 (23) into one of the moistened tyre holes. Operate the trigger
(28) and keep it pressed. The stud is pressed into the tire. Release trigger (28); 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.

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:
Disconnect the gun from the compressed air supply.
Release trigger: Slip off O-ring (30) from bushing (32) and dowel pin (29) appears.
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.
The gun must be set back to its initial state should you want to use it
on the studding machine.

6 Faults and troubleshooting
When unscrewing the intermediate piece (17), it must be held tight,
because of the strong compression spring which is in the gun. If
not, it can be ejected and pose great danger.
No. Cause Trouble shooting
6.1 Deformed or dirty stud jammed in
feeding pipe (13) or gun head.
Unscrew Union nut (18) and take the head (26)
off the gun. Now remove the jammed stud.
6.2 Stud in feeding pipe (13) in wrong
position (with shank leading)
Remove feeding tube and shake out stud
6.3 Trigger (28) get caught 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.
6.4 Worn spreader fingers (23) Unscrew Union nut (18) and take the head (26)
off the gun. Remove spring lock (21) and replace spreader finger (23)
6.5 Worn push rod (12) 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 replace hexagon nut if necessary.
6.6 Worn centering finger (24) Unscrew Union nut (18) and take the head (26)
off the gun. Remove spring lock (21), Union nut
and O-ring (19). Replace centering finger (24).
6.7 Worn separating finger (20) Unscrew Union nut (18) and take the head (26)
off the gun. Remove spring lock (21), Union nut
and O-ring (19). Drive off spring pin (22) with a
drift punch until it is possible to remove the
separating finger (20). Replace separating finger, consider that the separating finger may not
jam it should remain movable.
