Air Cleaner
Engine, Air Cleaner
The degree of engine wear depends largely on the cleanliness
of the induction air. The air cleaner prevents dust and other
impurities from entering the engine. Therefore, it is very
important that the air cleaner must be checked regularly and
maintained correctly.
Primary Filter, Maintenance and Replacement
When the alarm text "Clogged Air Filter" is shown or every 1,000
hours, the filter must be replaced or be cleaned. The period of
operation between filter replacements vary depending on the
working environment of the machine. In certain environments
the filter needs to be replaced more often.
• The filter can be cleaned according to instructions
which your authorized dealer will give you. However,
after the filter has been cleaned five times or if it is
damaged, it must be replaced.
NOTE: Make a mark on the decal at the end of the
secondary filter every time the primary
filter is replaced or cleaned.
• In connection with replacing the filter, the cover for the
air cleaner should also be cleaned. It works as a container
for particles which have not been trapped in the filter.
• Check that all hose and pipe connections from the air
cleaner to the engine induction manifold are tight.
Check tightness of hose clamps.
CAUTION
Never remove air cleaner filter while engine is running. This
will allow dirt to be sucked into engine and cause serious
engine damage. Always turn engine "OFF" before servicing
air cleaner.
