A low---pressure indicator with a warning lamp is
connected to the air cleaner. When the lamp (A) lights up
on the instrument panel, the filter must be cleaned. If the
warning light illuminates quickly in dusty conditions,
check the ejector pipe (1) is fitted properly, the models
A75n and A75L---A95L have dustvalve.
Cleaning:
--- Always stop the engine before cleaning. A blockage of
the air filter is indicated by a change of the engine beat,
smoky exhaust and reduction of engine power.
--- Check the inside of the air cleaner housing and the inlet
pipe. Dirt on these parts indicates that the filter element
is defective or has not been fitted properly.
--- Clean the filter element with compressed air, max. pres-
sure 500 kPa, or with an effective vacuum cleaner.
IMPORTANT: The filter element must not be cleaned
more than 5 times, after which it must be replaced. The
filter must be changed every 1000 hours in accordance
with the maintenance requirement:--- change of the safety
filter.
--- Hold up the filter element against the light (or shine a
flashlight through the centre hole) and inspect the ele-
ment.
--- If any holes are noticed the filter element must be chan-
ged.
