3.5.5 Automatic engine cut-off (APH 5020 – 6530)
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.
