8.1. General
Periodic maintenance for the extra equipment are in
section K, after each extra equipment.
NOTE: When the tool symbol of periodic
maintenance is illuminated in the display the service
work has to be carried out before the tool symbol

8.1.1. Air filters
Change air filter (1):

− After every 1000 hours
− After 5 cleanings, when the warning light of the air
cleaner has illuminated 5 times
Change safety air filter (2):

Unless it is necessary do not open the cover of the
air cleaner housing. Only associated with the
situations mentioned before. During the
maintenance check, that the cover of the housing,
pipes and unions are in good condition.
A low − pressure indicator with a warning lamp is
connected to the air cleaner.
When the lamp 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.
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. pressure 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 element.
− If any holes are noticed the filter element must be
changed.
8.1.2. Control Range Of Hydraulic
