5.4. Air Intake System
5.4.1. Maintenance
(only when engine is switched off)
Empty the dust bowl (7) regularly. The bowl should never be filled more than halfway with dust.
On slipping off the two clamps (3), the dust bowl can be removed. Take off the cover (6) of the
dust bowl and empty.
Be careful to assemble cover and bowl correctly.
There is a recess in the cover rim and a lug on the collector which should register.
Where the filter is installed horizontally, watch for “top” mark on cleaner bowl.
5.4.2. Changing filter element
CAUTION : Do not allow dirt to get into
the clean air end.
On removing the hexagon nut, take out
the dirty cartridge and renew or clean.
Wipe the cleaner housing with a damp
cloth, in particular the sealing surface for
the element.
NOTE : Unless the maximum number of
cleanings (up to 5 x) have been
done, the filter cartridge should
be renewed every two years or
4,000 hours operation.
