Welding operations
Before any welding operations on
the machine:
- Disconnect the battery, first at the
negative and then at the positive
pole.
- Disconnect the positive pole at the
alternator.
- Protect disconnected terminals
and plugs from short-circuiting
and contamination by covering
them with foil or adhesive strips.
Bring the welding current terminals
as close as possible to the welding
point.
The welding current must not flow
through the slewing ring, pin cou-
plings, link joints or hydraulic cylin-
ders.
Restore all electrical connections
after completion of welding opera-
tions.
When connecting the battery, con-
nect first the positive pole terminal
and then the negative pole terminal.
Never perform welding operations
unless you are qualified to do so.
Observe the accident prevention
regulations.
Any work on receptacles that con-
tain or have contained substances
- that are flammable or encourage
combustion,
- that are susceptible to explosion,
- that may develop noxious gases,
fumes, vapours or dusts during
welding operations
may be performed only under expert
supervision and only by experi-
enced personnel authorized to do
such work.
Detailed information on the proper
execution of welding operations is
given in the corresponding sections
of this manual.
Contact the O&K Service depart-
ment with any problems or ques-
tions arising.
If machine components have to be
dismantled, read and observe the
sections:
- "Assembly of working equipment -
