Adjustment of the spring balancer
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.
When starting up the saw, check the direction of rotation of the motor.
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 SK 40 E
There is a cold water connection available.
The saw blade cooling/saw blade rinsing is controlled by a manual valve.
Instead of the manual valve (tap), a magnetic valve can be installed.
