This Spare parts list/service instructions and the
enclosed Operator's Manual constitute the
Operating Instructions. Before using read both and
strictly observe safety instructions.
Service and repair
Attention! Always disconnect the tool from its air
supply and empty magazine before attempting any
repair. Always fix the cap with a torque wrench adjusted
to 8 Nm.
To replace driver blade
Loosen cap VC7104 (fig. 1). Invert machine and tap
gently on wooden surface to remove piston/driver blade
assembly (fig. 2). With a pin punch tap out pin
VC7330.
The driver blade can then be removed. Replacement of
the blade is a reversal of the above procedure.
To replace piston O-ring
See instructions "to replace driver blade", then replace
O-ring VC7326 (fig. 3) and grease with grease, or oil,
before refitting.
the plastic piston have to be deformed again to prevent
movement of the pin, which can then damage the
cylinder. In order to do this, lay a drift punch, diameter
3mm, across the hole (fig.4) and hit the punch drift with
a hammer so that the hole is deformed a little bit.
To replace bumper
With the piston/driver assembly removed always check
the bumper. Push out bumper from below with a
screwdriver.
To replace feeder bar and tension spring
(Two stick version Fig. 4 lower)
To release rail assembly remove cap screw
VC7363 and the rail stop assembly.
Withdraw rail assembly. It is now an easy operation to
replace the tension spring VC7099 or the pusher (fig.
4). Reassembly is a reversal of the above.
Changing of automatic valve
Remove pin VC7107and remove trigger. Remove valve
body and replace completely (fig. 5).
Adjustment of Cycle Speed of the Automatic Valve
The cycle speed of the automatic valve can be infinitely
varied between 0 - 1600 staples per minute. By turning
the adjusting screw
VC7111 anti-clockwise the frequency of the operation is
increased. With light pressure on the trigger the single
shot mode is achieved.
By further pressure on the valve trigger the tool works
with the frequency adjusted before.
If for one operation both the single shot mode and the
automatic shot mode are required, both sections can be
separated safely by adjusting the valve bushing
VC7118 with the special key, which is supplied as
accessory together with the stapler. By turning the valve
bushing clockwise the range of the single shot mode is
increased, whilst the range is reduced by turning the
bushing anticlockwise.
In case of malfunction of the valve loosen valve socket
VC7116 with the special key. Replace valve insert
completely or replace all O-ring. For reassembly grease
all parts with O-ring grease and check function.
