Operation Of Switch; Working With The Hook Cutter - EFA Z28 Betriebsanleitung

The hook cutter must be suspended in such a way
that it head section faces downwards. If required,
the tool can be realigned in vertical direction.
As the device weighs about 24 kg, there is a risk of
injury if it is dropped while being attached or
removed from the pulley system. Ensure that the
hook cutter is not jammed at the hooks. Always
proceed with special care when attaching or
removing the device from the pulley.
When the cutter is not used, it must be stored in
such a way that persons cannot inadvertently come
into contact with its blades, as they are extremely
well honed.
3.1.2 Hydraulic unit
The hook cutter blades are operated hydraulically.
Connect the cutter to a hydraulic unit (for
installation and commissioning, see separate
operating manual) and
fill filtered hydraulic fluid through the refill
opening.
Connect the hydraulic unit to terminal box for
power supply (Y-circuit 3: 400 V ~, 50 Hz).
The hydraulic hoses supplied with the unit have
threaded connectors of different diameter so that
lines cannot be confused.
3.1.3 Connecting and disconnecting of cutter
The cutter is equipped with a plug-in nipple return a
coupling body at the feed line. To connect the
cutter, proceed as follows:
Close compressed air line and press two-hand
safety switch (see chapter 3.2.1 "Switching ON"
(page 3)) at the hook cutter once.
Disconnect hydraulic hose (1 - 13) with closed
feed line from the hose kit.
To disconnect the lines, open the safety locking
ring at the coupling body by turning the locking
ring until it disengages.
The hydraulic couplings are self-locking, so that no
fluid can escape when the line is
disconnected.
Protect coupling and adapter
components against contamination!

3.2 Operation of switch

Prior to switching on the cutter,
read the instructions in this
manual carefully and ensure that
the tool is properly connected.
The hook cutter is equipped with a two-hand safety
switch mechanism.
3.2.1 Switching ON
Hold cutter firmly!
Simultaneously press the switching levers at the
front and at the rear to close the cutter.
3.2.2 Switching OFF
Release the switching levers; the cutter opens.
The cutting procedure can be terminated at any
time, or repeated.

3.3 Working with the hook cutter

Never reach into the operating
range of the cutting blades, as
there is a risk of dismemberment!
Always wear goggles or other
effective eye protection!
3.3.1 Cutting procedure
Ensure that the hydraulic unit is in proper
working order and ready for operation.
Hold cutter firmly, place at the section you wish
to cut and operate the switching levers (see
chapter 3.2 "Operation of switch" (page 3)).
For cutting, the meat can be suspended or placed
on a workbench. By positioning the cutter properly
where the meat is to be cut and by operating the
two-hand switches, a clean cut can be achieved.
Place the cutter at right angles to the
meat you wish to cut. Ensure that the
meat is placed between the blades and
not just at the tips, as the blades might
otherwise break.
There is no need to bleed the hook cutter, as the air
is automatically released from the bleeding filter of
the hydraulic unit after a number of cuts have been
completed.
