Initial Operation; Spring Balancer - EFA Z 13 Betriebsanleitung

3.1 Initial operation

Important information, e.g. technical
data sheets, drawings and parts lists
can be found in Annex A (p. 25).
Connect the guillotine to the
works network only when it has
been switched off!

3.1.1 Spring balancer

The machine must always
be operated in combination
with a weight relief system
(spring balancer).
Install the spring balancer
with a trolley to a higher
element above the place of
work or to the ceiling.
Information on fine adjustment of the spring bal-
ancer can be found in Chapter 4.5 "Adjustment of
the spring balancer" (p. 20).
Suspend the guillotine so that it is as top-heavy as
possible. The vertical position can be adjusted, if
necessary.
In view of the weight of approx.
31 kg, there is a danger of the
machine slipping or falling when
attaching or releasing the weight
relief system. Pay attention also
that the machine does not jam on
the trigger snap or on the hook of
the guillotine.
Work cautiously!
When the guillotine is not in use, store it so that
there is no risk of accidental contact with the blades
as they are sharp.
3.1.2 Air conditioner
If the compressed air connection is not made cor-
rectly and with a high water content in the com-
pressed air, there is a possibility of water escaping
at the connection point. Therefore pay attention to
correct connection of the hose and to a low water
content in the compressed air (empty the water trap
at regular intervals).
The water trap does not form part of the machine
and has to be installed upline of the machine.

An air conditioner is installed on the hydraulic power
pack (observe the flow direction arrow on the con-
ditioner).
If no dried compressed air is available, a water ab-
sorber has to be provided by the customer.
Oil filling : Use oil (001365611/12)
Oiler setting: 1 drop of oil every approx. 15 cuts
Pressure gauge setting: Working pressure 6-8 bar.
3.1.3 Hydraulic power pack
The cutting mechanism of the guillotine functions
hydraulically. Connect the guillotine to an operation-
al hydraulic power pack (see also the separate op-
erating manual for the hydraulic power pack), by
pouring finely filtered hydraulic oil (001365614)
into the filler opening provided (approx. filling
volume 50 l) and
connecting the power pack to the terminal box
(Y-circuit 3: 400 V ~, 50 Hz).
The hydraulic hoses to be used have threaded fit-
tings of different sizes and therefore cannot be con-
nected incorrectly.
Connection of hydraulic hoses
Connect the hydraulic hoses inlet M16 x 1.5 and
return M14 x 1.5 with the threaded fittings to
the hydraulic power pack and with the threaded
hydraulic couplings to the guillotine.
Screw the couplings firmly into their end posi-
tion and they are self-locking when loose.
Venting of the guillotine is not necessary, as the
air escapes from the power pack via the hydrau-
lic hoses after a few actuations.
Screw the control hose unit (59-68) with 2 hex-
agon head bolts (64) to the guillotine.
Connection of control line to guillotine: Connect
line (66) to distributor (2). Observe the position
of the connection.
Push the multi-core lead (66) through the lower
opening of the housing of the pneumatic con-
troller (hydraulic power pack).
Only 3 cores are required for the pneumatic
controller. The colourless core is not connected.
Completely push the red lead into quick-coupler
"a" and the yellow lead into quick-coupler "b" of
the two-hand safety block.
Completely push the blue lead into quick-cou-
pler "Pl" of the Y-connection.
Connect the compressed air supply with a com-
pressed air hose (NW. 6 mm) to the fitting with
the outside thread. Working pressure range 5-8
bar. Do not install an oiler in between.
