3. Operation
3.5 Automatic engine cut-out
The engines are equipped with a safety engine cut-out.
The engine switches off automatically if
– the oil pressure is too low
– the film of lubricating oil is unstable as a result of
• excessively high oil temperature
• incorrect basic viscosity (too low)
• dilution of the oil by fuel or water
– the lubricating oil filter is blocked
– there is a leak in the oil relief valve
– there are leaks in pipes and seals
–
the oil pumps and bearings are worn.
Attention
If the oil level is too low or the machine is tilted too much,
this can lead to the mixture of air and thus to a loss of
viscosity.
If the engine cuts out because the supply of lubricating oil is
insufficient, proceed as follows:
– Locate the fault and have it rectified.
– Press the hand lever for a few seconds.
– Start the engine.

3.6 Air filter maintenance indicator
B6599028.cdr
The engine is equipped with a maintenance indicator for dry air
filters. If the filter element is soiled, underpressure causes a
rubber bellows to contract.
In this case, switch off the engine and clean or replace the filter
element.
