Smaller conductor cross sections and long cables lead to a drop in voltage and cause
the extension cable to overheat.
Before use, extension cables must always be unrolled from the reel.
5.1.7 Cooling water supply
At a water temperature of 30 °C a water flow rate of approx. 4 l/min is necessary to cool
the drive unit.
The machine's automatic cut-out will be activated in the event of inadequate cooling.
Use only clean cooling water.
Where pressure in the water supply line is low, a non-return valve should be fitted in order
to prevent dirty water finding its way into the water supply.
5.2 Setting up the system
5.2.1 Drilling the through holes
The location and positioning of the through holes has a direct influence on cutting
accuracy.
On very thick walls or where cutting tolerances are minimal, we recommend use of rig-
based diamond coring machine for drilling the holes.
On thin walls or where cutting tolerances are greater, a rotary hammer can be used to
drill the holes.
We recommend a drilling diameter of at least 16 mm, but the diameter should be at least
4 % of the thickness of the object to be cut.
5.2.2 Fastening the base plate
WARNING
Warning Use of vacuum pads for fastening the base plate is not permissible.
▶ Vacuum pad fastening is not permissible under any circumstances.
