4.2.2 Monitoring during operation
The machine features a warning buzzer
emitting a signal if the following
malfunctions occur:
⇒ Insufficient engine oil pressure (12/20)
⇒ Air filter clogging indicator (12/21)
⇒ Excessive coolant temperature (12/25)
If the engine and the machine are put
into operation without prior remedy of
the malfunction, severe damage to the
engine may result!
• As soon as the warning buzzer comes up check
which indicator lamp is activated and proceed
accordingly.
• If the battery charge lamp (12/18) or the engine
oil pressure lamp (12/20) light up, switch off the
engine immediately and determine the cause. If
necessary, call for service personnel.
• If the air filter maintenance indicator (12/21)
lights up, perform the necessary maintenance
work.
• If the permitted coolant temperature (12/25) is
exceeded, stop work, open the engine hood
and keep the engine running at idle speed to
allow it to cool down. Once the engine has
cooled down, turn it off and determine the
cause, or call for service personnel.
• If the hydraulic oil filter clogging indicator
(12/22) lights up, replace the filter element and
determine the cause of clogging.
When the hydraulic oil is cold, the
hydraulic oil filter clogging indicator may
light up briefly. It will go out once the
operating temperature has been
reached.
4.2.3 Switching off the engine
Do not switch the engine off when at full
throttle, but allow it to run for a short time
at low revs without load.
• Move the manual throttle to low idle.
• Turn the ignition key (12/34) to "0".
• The engine stops automatically.
