SECTION 3 - LUBRICATION AND MAINTENANCE
3-10
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 sealing properly.
2. Clean the primary element using low air pressure
(30 PSI or less). Blow dust from the inside to the
outside of the element (opposite to normal air
flow through 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.
