3.5.5 Automatic engine cut-off (AVH 5020 – 6030)
Machines are equipped with a safety engine cut-off. The engine
switches-off automatically if
•
the oil pressure is too low
•
the film of lubrication oil is unstable as a result of
•
excessively high oil temperature
•
incorrect baisc viscosity
•
dilution of the oil by fuel or water
•
the lubricating oil filter is blocked
•
a leakage in the oil relief valve
•
leakages in pipes and seals
•
the oil pumps and bearings are worn.
If the engine cuts-out because the supply of lubricating oil is in
-
sufficient, proceed as follows :
•
Locate the fault and have it rectified.
•
Press the lever few seconds.
•
Start the engine.
3.5.6 Air filter maintenance indicator
The motors are equipped with a maintenance indicator for air fil
-
ters. In case of pollution of the filter element the rubber bellow
contracts by underpressure.
In this case, switch-off the motor and clean or replace the air-fil
-
ter.

Attention
If the oil level is too low or the machine is tilted too
much, it can lead to an admixture of air and thus to
a loss of viscosity.
