3.1.1 Spring balancer
The machine must always be operated in
combination with a weight relief system (spring
balancer). Use a sliding crane trolley to mount
the spring balancer on an element above the
working area or on the ceiling. For details
about how to fine-tune the spring balancer
refer to section "Spring balancer adjustment".
Suspend the splitting saw top-heavy, if
possible. The vertical position can be
adjusted, if necessary.
In view of the considerable weight, there is a
danger of the machine slipping or falling when
attaching or releasing the weight relief system.
Pay attention that the device does not catch
on the snap hooks or the hook of the splitting
saw. Work cautiously!
When the splitting saw is not in use, store it so
that there is no risk of accidental contact with
the saw belt as this may cause injury.
3.1.2 Electrical Connection
The splitting saw is operated with electrical
energy and must be connected to the mains
power supply by a qualified electrician in
accordance with statutory regulations and the
regulations of the local public utility.
Prior to connecting the safety isolating
transformer to the primary side, check
the operating data of both the mains
and the transformer circuitry.
When electrically connecting the
controller to the transformer's
secondary side, ensure that the wiring
complies with section "Cross-sections
of lines".
Refer to the labelling and the wiring
diagram to attach the connection
cables of the machines.
The machines have been designed
compliant to VDE directives and the
EC machinery directive. For reasons
of operating safety, you are not
allowed to modify or reconstruct the
machine and the safety equipment
(e.g. lid guard, two-hand safety circuit)
in particular.
Check the direction of motor rotation.

3.1.3 Water connection
The machine is designed for automatic
cleaning using cooling and hot water. The
water connections are labelled "K" (cold water,
blue) and "H" (hot water, red) respectively.
Water supply is actuated by solenoid valves
set by the controller. Timing relays allow the
cleaning cycle to be adjusted. We recommend
installing manual check valves upstream the
solenoid valves.
The hot water used to
rinse/clean the inside of
the splitting saw must
be at least 82 °C hot!
3.2 Switching on/off
3.2.1 Switching on
Do not switch on the
saw until the saw belt is
correctly placed around
the driving and belt
return wheels as well as
in the two guiding
implements!
