SECTION 3 – LUBRICATION AND MAINTENANCE
3-11
Air Cleaner Primary Element
NOTE: Clean the primary element after every
100 hours of service. Extremely dusty conditions
may require more frequent service intervals.
1. Pull the primary element ③ from the
canister. Clean any loose dirt from the
canister, and inspect the end of the canister
for dirt which may prevent the new element
from seating properly.
2. Clean the primary element using low
pressure air (30 PSI or less). Blow dust from
the inside toward the outside of the element
(i.e., opposite to normal air flow through the
element).
IMPORTANT: Be careful not to rupture the filter
element. Maintain a safe distance between the
air nozzle and the filter element when directing
air up and down the clean air side of the element
pleats.
3. After cleaning the element, check the inner
diameter seals for damage. If damage is
present, replace the primary element.
Change the element after six cleanings or
once a year.
4. Reinstall the primary element by inserting it
into the canister and pushing on the end of
the element until it is seated against the
canister.
NOTE: Place a light inside the element to check
for paper leaks or for bonding of the paper to the
end plate. If any leaks are found, replace the
element.
NOTE: If element is not inserted far enough into
canister, the end cap cannot be installed.
5. Place the end cap onto the canister body
and attach spring clamps. Make sure the end
cap is locked in place and not loose.
IMPORTANT: Never tap the element with hard
objects or against a hard surface. This may dent
or break the element end cap seals.
IMPORTANT: Failure to obtain a good seal
between elements and the canister may cause
major engine damage, by allowing dirt to enter
the engine.
