4.1.2 Checking the blade clearance
In order to avoid breakage, the blades must always
be adjusted without clearance but with free move-
ment. Adjustment is made with hex. nuts (18, 19).
4.1.3 Blade installation
Before reassembling the guillotine, clean the re-
moved parts, inspect for wear and replace, if neces-
sary. Grease all sliding points with EFA Special
Grease.
4.2 Valve replacement
Replacing the valve parts
Remove screw (36) to release handle (35).
Remove snap ring (32) and pull out valve (26 -
31), clean the removed parts, inspect for wear
and install again in the reverse order.
Always replace the valve (26 - 31) together with the
snap ring (32).
4.3 Piston changing
Replacing the piston parts
1. Disconnect the pressure hose from Z13
2. Remove the two sheet covers (8)
3. Remove two screws (4) and two screws (9)
from bracket (10)
4. Pull out the two blades (12) and bracket (10) to
the front to remove
5. Remove flange (13 ) from guide (43) using an
impact wrench
6. Remove the four cylindrical screws (37) of guide
(43)
7. Loosen the cylinder barrel (51)
8. Removal:
Clamp guide (43) and unscrew cylinder barrel
(51) with a hook-type wrench. If necessary, first
remove the two screw fittings (38-40 and 52-
58). Caution! Leak-off oil runs out!
9. Pull of cylinder barrel (51) and remove the indi-

14.Reassemble in the reserve order (points 13 to
1), oil parts (46 and 49) lightly before installa-
tion (pay attention to compatibility with the
hydraulic oil).
Caution:
The guide (43) and the cylinder barrel (51) must be
secured with Loctite 542!
Install piston (48) only with mounting cone and
expander sleeve - removal is possible only after
heating to 150° C.
Cylinder barrel screwed into guide (43) and
secured with Loctite 542.
Install screw fitting (40, 52) with Teflon tape
Inspect bushing (44) occasionally (barely sub-
ject to wear)
Grease all sliding points and blades (12) with EFA
Special Grease (see Chapter 6.1.3 "Lubricants and
hydraulic oil" (p. 22).
4.4 Hydraulic power pack
At least once a year, drain the oil filling, inspect for
soiling and replace if necessary. (See also Annex
3.1.3 "Hydraulic power pack" (p. 17) and separate
operating manual for the hydraulic power pack).
4.5 Adjustment of the spring
balancer
The fine adjustment of the spring balancer is effect-
ed via the PLUS/MINUS screw on its housing (see
Fig. 4).
Figure 4: Spring balancer
Turn the screw towards MINUS until the device
is suspended freely with the spring balancer at
working height
If the guillotine cannot be pulled out, the spring bal-
ancer is jammed and a readjustment is necessary:
Turn the screw in PLUS direction until the guillo-
tine can be pulled out and start the fine adjust-
ment again (see above).
