Engine air filter elements
Primary filter
When the display unit shows "Clogged Air Filter" or every
1000 hours, the filter should be cleaned or replaced.
If the lamp still lights after the service, the safety filter element
must be changed. Refer to Secondary filter page 171. Do not
clean the safety filter element.
NOTE! The primary filter may only be cleaned a maximum of
three times. Thereafter, it should be replaced. Make a mark on
the end of the secondary filter every time the primary filter is
cleaned or replaced.
NOTE! Use approved respirator when cleaning filters.
The length of time between filter changes depends entirely on
the operating environment of the machine. It may be neces-
sary to change the filter more often.

Remove the primary element from the housing. Take care not
n
to damage either the primary or secondary filters.
Do not attempt to clean the primary element by striking it. This
n
