Electronic components can be destroyed by stray voltage during arc
welding processes. For this reason:
● Disconnect the remote control cable from the control console.
● Disconnect all cables leading to the receiver of the radio remote
control system.
● Close connector sockets with caps.
● Disconnect the positive and negative leads from the battery.
Clean the machine and its surroundings of dust and flammable sub‐
stances and make sure that the premises are adequately ventilated
before carrying out welding, flamecutting and grinding operations,
otherwise there is a risk of explosion.
3.3 Working on the placing boom
Only carry out maintenance and repair work on the placing boom if
the placing boom is folded or properly supported, the engine is
switched off and the support legs are secured.
Support the placing boom arms before starting work on the valves,
cylinders or hydraulic lines on the boom.
The delivery line was installed without tension with the placing boom
in the driving position and can only be replaced without difficulty in
this condition. Stresses may be generated on folding if the delivery
line is replaced when the placing boom is unfolded.
Do not remove the entire delivery line but rather replace the delivery
line boom arm by boom arm, for example. Otherwise, the pivot points
of the new delivery line will have to be redetermined using special
equipment.
