Welding work
WARNING!
Material damage due to welding work on the
machine!
Welding work on the machine can cause high
material damage.
Therefore:
•
Always disconnect the negative pole of the
battery in advance.
•
Disconnect the plug connection to the
alternator regulator.
Batteries
•
Observe the following safety factors
•
Batteries produce explosive gases.
•
Keep away from naked flames and other
ignition sources. Do not smoke.
•
Do not lay any tools on the battery.
•
Always disconnect the negative pole of the
battery before performing work on the
electrical system.
•
Do not mix up the + (plus) and - (minus) poles
of the battery.
•
Connect the plus cable first and the minus
cable afterwards when installing the battery.
•
Disconnect the minus cable first and the plus
cable afterwards when removing the battery.
•
Always avoid short-circuits and earth contact
of live cables.
•
In the case of faults in the electrical system, first
check the cable connections for good contact.
•
Replace defective indicator lamps immediately.
•
Do not remove the ignition key during
operation.
•
Do not disconnect the battery while the engine
is running (occurring voltage peaks can
destroy electronic components, e.g. the
alternator regulator).
•
Do not spray parts of the electrical system
during engine cleaning with a water jet or
high pressure jet.
•
Always disconnect the minus terminal of the
battery and disconnect the plug connection to
the alternator regulator for welding work.
WARNING!
Risk of injury due to incorrect handling of
batteries!
Batteries must be handled with particular caution.
Therefore:
•
Never expose batteries to high
temperatures. There is a risk of explosion.
•
Escaping liquid due to incorrect use can
result in skin rashes. Avoid contact with
the liquid. Always rinse with a lot of water
in the case of contact with the liquid. If the
liquid gets into the eyes, rinse immediately
with water and contact
a doctor
immediately.
