5. Connection and start-up
5.1 Initial start-up
Caution! Danger of malfunctions and injuries!
Installation work is only allowed to be carried out by
authorised specialist personnel.
Danger! Do not come into contact with the uncovered
cutting edges.
5.1.1 Spring balancer
The machine must always be operated in combination with a weight relief
device (spring balancer), see Fig. 5.1 and Fig. 5.2.
The spring balancer is secured with a safety chain (2), which
must be secured in a fixed position irrespective of how the
spring balancer is suspended.
Attach it to a higher element above the workplace if possible or
to the ceiling.
Hang the cutter with the head uppermost. The vertical
alignment can be readjusted if necessary.
Danger! Due to the weight, see Tab. 3.1 Technical
data, there could be a hazard due to the
machine slipping or falling when the weight
relief device is attached or detached.
Danger!
Please note that if the rope rebounds when
unloaded, it is very dangerous for people and
the spring will also be irreparably damaged.
The maximum load specified on the
nameplate must not be exceeded.
Also make sure that the machine does not jam either on the snap
hook or on the hook of the cutter. Be careful!
Adjustment of the spring balancer
The fine-tuning of the spring balancer is carried out via the plus/minus (+/-)
hexagon screw on its housing.
To do this, turn the screw with the socket wrench (1) in the direction of
minus (-) until the device is freely suspended and balanced (with the tension
spring) at working height.
If it is not possible to pull out, the spring balancer is blocked and
readjustment is necessary.
Turn the screw with the socket wrench (1) in the direction of plus (+) until
pulling out is possible and start the fine adjustment again.
When the cutter is not in use, place it in such a way that there is no accidental
contact with the cutting edges, because they are sharp.
Fig. 5.2 –Fine-tuning of the
spring balancer

EFA cutters Translation of the original operating instructions-EN
Rev.00 –05.2020

5.1.2 Hydraulic unit
Danger! Secure the unit sufficiently so that it cannot
fall down.
The cutting mechanism of the EFA cutter works hydraulically. Connect the cutter to a hydraulic unit that is ready
for operation (see also separate operating instructions for the hydraulic unit). The hydraulic hoses to be used
have threaded connections of different sizes to avoid incorrect connection.
5.1.3 Coupling and uncoupling the cutter
The cutter is equipped with a plug connection (1) on the flow and a coupling (2) on the return.
Proceed as follows:
1) Switch off the compressed air supply to the cutter and operate the switches on the cutter once. The
hydraulic hose cpl. is now depressurised and the hose unit (3, 4) can be uncoupled.
2) Uncouple the depressurised hydraulic hose cpl. with closed flow (3) from the hydraulic unit.
3) To uncouple, loosen the safety closing ring (4) on the coupling. To do this, turn the closing ring (4) around
until the locking mechanism is released.
The hydraulic couplings are self-locking so that no oil leaks when uncoupling.
Important! You should protect the plug connection and
coupling from dirt!

6.2 Working with the cutter
Danger! Never reach into the cutting edge area of the cutter,
otherwise you could cut off limbs!
Warning! Wear eye protection or protective goggles when working.
Wear hearing protection during your work.
Work step
The hydraulic unit must be ready for operation.
Hold the cutter securely, place it in the correct position and operate it according to section 6.1 Switch operation.
The cutting process can be carried out when the animal/meat is either hanging up or lying on the table. The
instrument operator secures the cutting area and the cut is made by operating the switch (On).
Caution! Always position the cutter at right angles and in the cutting
edge area (not with the tips of the blades). Otherwise there
could be a knife breakage as a result of an overload.
For safety reasons, the bracket (1) of the cutter, which can
be mounted on both sides, must be mounted on the same
side as the hand you are using to hold the material during
the cutting process, i.e. on the right for left-handed persons
and on the left for right-handed persons.
The safety device (bracket 1) is not allowed to be either
changed or removed.
6.2.1 Operational safety
Hold the machine securely by the handle (1 handle or
2 handles).
Be especially careful when breaking, the cutting edges can
close in less than 1.2 seconds.
Always position the instrument at right angles and in the cutting edge area, so that no knife breakage occurs
as a result of overloading.
For safer handling (guiding), hang the cutter on a spring balancer, see section 5.1.1 Spring balancer.
