Initial Operation; Spring Balancer - EFA Z 08 Betriebsanleitung

3.1 Initial operation

Important information, e.g. technical
data sheets, drawings and parts lists
can be found in Annex A "" (p. 32).
Switch off the cutter before con-
necting to the works mains!

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. 27).
Suspend the cutter so that it is as top-heavy as pos-
sible. The vertical position can be adjusted, if nec-
essary.
In view of the weight of > 4.5 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 cutter. Work cautiously!
When the cutter 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 an excessively higher water content
in the compressed air, there is a possibility of water
escaping at the connection point. Therefore pay at-
tention 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 cut-
sPressure gauge setting: Working pressure 6-8 bar.
3.1.3 Hydraulic power pack
The cutting mechanism of the cutter functions hy-
draulically. Connect the cutter to an operational hy-
draulic power pack (see also the separate operating
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 hydraulic hoses (70+72), inlet M16 x
1.5 and return M14 x 1.5 to the threaded fittings
on the hydraulic power pack and to the screw-
type hydraulic couplings (71+73) on the cutter.
Screw the couplings firmly into their end posi-
tion and they are self-locking when loose.
Venting of the cutter is not necessary, as the air
escapes from the power pack via the hydraulic
hoses after a few actuations.
Screw the control hose unit (76-83) with 2 hex-
agon head bolts (79) to the cutter.
Push the multi-core lead (76) through the lower
opening in the housing of the pneumatic con-
troller.
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 port to the sleeve
with the outside thread using a compressed air
hose (ID 6 mm). Working pressure range 5-8
bar.
Do not connect an oiler between the port and
the sleeve.
