3.1 Commissioning
3.1.1 Spring-loaded pulley
The machine may only be operated in conjunction
with a spring-loaded pulley. The pulley must be
attached to a beam above the workplace or the
ceiling. For detailed information on how to install
and balance the spring-loaded pulley, please refer
to chapter 4.5 "Adjustment of spring-loaded
pulley" (page 7)
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 machine weighs about 4.5 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 saw 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 (volume: approx. 8 l).
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 feed a
coupling body at the return line. To connect the
cutter, proceed as follows:
When connecting the hook cutter
to the pressure supply line,
ensure that it is switched off
For detailed information, technical
data, parts lists and drawings of the
equipment, see Appendix A (page 11).
Disconnect pressure air and operate valve lever
(27) once. The hydraulic hoses (33, 36, 37 and
39, infeed/closed) are now depressurised. The
hose unit (33, 35-41) can now be
disconnected.
Disconnect hydraulic hose 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.
3.2 Operation of switches
The hook cutter is equipped with a two-hand
safety switch mechanism.
3.2.1 Switching ON
Hold cutter firmly!
Simultaneously press the switching lever and
the valve arm to close the cutter.
3.2.2 Switching OFF
Release the valve arm; the cutter opens.
The cutting procedure can be terminated at any
time, or repeated.
Protect coupling and adapter
components against contamination!
Prior to switching on the cutter,
read the instructions in this
manual carefully and ensure that
the tool is properly connected.
Before switching on the cutter,
check blades for correct play and
ensure that the handle is properly
mounted.
