Work procedure for wire cutting

When all the equipment has been assembled cutting can
start. In order for the saw to cut as efficiently as possible it
should be started as follows:
1. Assemble the pressure reduction block supplied with
the wire saw on the hydraulic unit according to the
instructions on the block.
2. Connect the two smaller hydraulic hoses to the
pressure reduction block. The hoses in the hose
assembly marked with a red disc by the coupling shall
be connected to the hose on the pressure reduction
block that is also fitted with a disc.
3. Close the valve on the pressure reduction block by
turning the knob anti-clockwise until it stops and then
two turns back.
4. Start the engine's working speed by pressing the green
button on the remote control once.
The engine on the diesel-driven generating set
changes from idling to working speed and starts to
produce a flow.
To stop the flow and to get the hydraulic unit's motor to
idle, press the green button on the remote control once
again.
5. Set the feeding flow on the unit to max by turning the
control on the remote control clockwise.

6. Tension the wire by carefully turning the knob on the
pressure reduction block clockwise until the wire is
tensioned sufficiently. Make sure to always check that
the wire is seated correctly in all the wheels on the
saw.
7. Start the motor's rotation by turning the control for
motor rotation on the remote control clockwise.
8. Carefully increase the motor speed by turning the
control for motor rotation. A suitable working pressure
when cutting usually lies between 100 and 130 bar, but
varies depending on how many wheel sets are used in
the magazine, how much wire is in use and the
hardness of the material to be cut.
9. When material is cut away the working pressure can
drop, which is shown on the display, and the magazine
must be tensioned. Do this by turning the knob on the
pressure reduction block clockwise.
