General Maintenance
2. Remove the primary element (1). Inspect the element for damage. Dam-
aged elements should never be reused.
3. Thoroughly clean the interior of the air filter canister (2) and vacuator valve
(3).
4. If replacing the inner element (4) at this time, carefully slide the element
out. Always discard this element and replace with a new element.
5. Slide the new primary element over the inner element making sure the
sealing edge is flush with the base of the air cleaner.
IMPORTANT! DO NOT apply any type of petroleum product to the sealing surface
of the filter in an attempt to get a more positive seal. This will cause sealing surface
damage and allow dirt to by-pass the filter. Use liquid dishwashing soap (Ivory,
Dawn, etc.) on the seal of the filter only.
6. Position the canister cover (5) in place, turn clockwise to lock into position
and secure in place by pushing the air cleaner cover lock (6) all the way in.
B. Air Intake System-Inspection
(1000 Hour Intervals)
Inspect the intake piping for cracked hoses,
loose clamps or punctures which can allow dirt
or debris to enter the combustion chamber. If
dirt or debris are allowed to enter the
combustion chamber, they can severely damage the engine. If necessary, tighten or
replace parts to prevent air intake system leakage.
