position independent of the suspension of the spring balancer.
Use a trolley to attach the spring balancer to a higher element above
the workplace or to the ceiling.
Danger! Do not come into
contact with the sharp
saw blade.
Danger! Due to the weight, there
could be a hazard due to
the machine slipping or falling when the weight
relief device is attached or detached.
Also make sure that the machine does not jam either on the snap hook
or on the hook of the reciprocating saw.
Be careful!
Danger!
When hooking in the cable of the spring balancer,
the spring loaded rope can whip around if the snap
hook is not properly hooked.
Please note that if the rope rebounds when
unloaded, it is very dangerous for people. The
spring will also be irreparably damaged. The
maximum load specified on the nameplate must not
be exceeded.

The fine-tuning of the spring balancer is carried out via the plus/minus (+/-)
screw on its housing (1).
To do this, turn the screw 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 a new
adjustment is necessary.
Turn the screw in the plus direction (+) until pulling out is possible and
start the fine adjustment again.
5.1.2 Electrical connection
The saw is operated with electrical power. It must be connected by a qualified
electrician in accordance with the legal regulations and those of the local energy
supply companies.
For electrical machines, a fuse must be provided on the operating side.
If the operating voltage does not correspond to a safety extra-low voltage, a residual current circuit breaker
(RCCB) must be installed on the operating side.
Before connecting the safety isolating transformer on the primary side (only for safety extra-low voltage), the
connection data of the transformer must be observed. Furthermore, the existing power system type must be
taken into account. Fuse protection of the transformer must be provided on the operating side.
The cable cross-sections must be dimensioned accordingly for the electrical connection of the connecting
cable between the safety isolating transformer and the control (only with safety extra-low voltage).
The connecting line of the saw must be connected according to the electrical circuit diagram supplied.
The saw has been designed and built according to the Machinery Directive 2006/42/EC.
Unauthorised changes and modifications, especially to the safety devices of the saw, are not permitted for
reasons of operational safety and, if any such changes are made, the manufacturer's guarantee and liability
shall be invalidated.
5.1.3 Water connection
EFA SL 50-18, EFA 67 and EFA 69
There is a cold water connection available.
The saw blade cooling/saw blade rinsing takes place via
a ball valve with manual operation (1).
A magnetic valve can be installed instead of the ball
valve (EFA 67 and EFA 69 only).

6 Handling
6.1 Switch operation
Important! The reciprocating saw must not be switched
on before the operator has read these
operating instructions and the saw has been
connected correctly!
Danger! The saw blade must be correctly
mounted and firmly seated.
6.1.1 Switching on
Danger! Ensure that the saw is switched
off prior to connecting it to the
plant network.
Before switching on, the following points must be checked without fail!
An early failure of the saw blade as well as problems in the slaughtering
process can thus be avoided to a large extent.
Before switching on, check that:
the reciprocating saw is operational;
the saw blade is correctly inserted and screwed tight.
A sharp saw blade was mounted directly before starting work,
see section 7.1 Saw blade change;
the suspension (spring balancer) is correctly mounted and is
operational;
the general safety instructions have been taken into
account, see chapter 2 Safety.
The machine is equipped with a handle (A) and a
switching handle (B). To switch on, press the
switch with your fingers, see Fig. 6.1 and Fig. 6.2.
6.1.2 Switching off
Release your fingers from the switch to turn off.
The switch switches off automatically due to a return spring.
Important! The saws must be held with both hands
for the run-down phase of 3 seconds!
6.2 Working with the reciprocating saw
Danger! Never reach into the cutting area of the
running saw blade, otherwise you could
cut off limbs!
Warning! Wear eye protection or protective
goggles when working!
Hearing protection must be worn during
continuous operation!

6.2.1 Operation
Before use, check that the operating data of the mains and the device match up.
Attention!
Make sure the guide and the saw
blade are as straight as possible when
sawing.
Do not bend! Improper handling will
lead to increased wear!
Warning!
For safety reasons, EFA
reciprocating saws must be
held with two handles.
Never work one-handed!
EFA SL 50-18, EFA 67 and EFA 69
Hold the reciprocating saw securely by both handles and switch on.
Guide it into the carcass while it is running.
Kick-back can occur when touching on bone.
Only remove the saw from the carcass while it is running and only switch it off afterwards.
See also section 6.1 Switch operation.
6.2.2 Operational safety
For safety reasons, EFA reciprocating saws must be held with two handles.
Never work one-handed!
Do not carry the saw by the switching handle, it could start unintentionally.
Be especially careful when switched on.
Do not remove protective devices from the saw.
Do not tilt or jam the saw blade.
Never reach into the area of the saw blade when it is switched on.
Do not put the device down until the saw has come to a halt (run-down time approx. 3 seconds).
For safer handling (guiding), the saw must be suspended from a spring balancer, see section 5.1.1 Spring
balancer.
Regularly check the suspension for damage.
Observe general safety regulations, see chapter 2 Safety.
