SERVICE CHECKS
Air Filter - Check (Condition)
Engine performance and durability will be severely affected if the quality of the air intake is poor.
A dirty and blocked air cleaner element will reduce the amount of air entering the combustion
chamber which can cause engine mis-firing, black smoke and low output power.
A dirty and blocked air filter can also lead to abrasion of the cylinder bores and valves (referred to as
‘dusting’). This will cause excessive oil consumption, black smoke, low output power and a reduced
engine life.
Refer to the machine's operator handbook for the air filter element removal and replacement
procedures.
Inspect hoses and fittings for splits and poor clamping which may allow unfiltered air to enter the
engine.
In hostile environments, change the air filter elements more frequently.
