Maintenance
Safety instructions for maintenance
It must be ensured that gas fuel systems are
adjusted, so that the levels of harmful sub-
stances in the exhaust gases are set at the
lowest possible value (CO concentration less
than 0.1 vol.-% idling when the engine is at
operating temperature) .
When replacing individual system parts, the
manufacturers’ installation instructions must
be observed . Cylinder and main shut-off
valves should be closed when doing so.
The condition of the electrical system of in-
dustrial trucks running on LPG must be kept
under constant surveillance . Sparks may
cause explosions if system parts containing
gas are leaking. After an industrial truck run-
ning on LPG has been shut down for a lengthy
period, the storage room must be ventilated
thoroughly before starting up the vehicle or its
electrical system.
When working in maintenance workshops,
cylinder and main shut-off valves should be
closed and the LPG cylinders protected from
heat.
Before pauses in operation and finishing op-
eration it should be checked by a responsible
person whether all valves, in particular cylin-
der valves, are closed .
Work involving fire, specifically welding and
cutting, should not be carried out in the vicinity
of LPG cylinders .
LPG cylinders, even when empty, must not be
stored in workshops.
Safety devices
After maintenance and repairs, all safety de-
vices must be reinstalled and checked for
proper functioning.
Set values
The device-dependent set values must be
observed when making repairs and replacing
hydraulic and electrical components. These
are listed in the appropriate sections.
