Air Cleaner Primary Element - Shibaura ST450 Operator's Manual

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) in Figure 3-14,
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 (200kPa 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.
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, push
in on end cap, and rotate clockwise. 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.
