8 MAINTENANCE & LUBRICATION
8.5 ENGINE : EVERY 100 HRS ______________________________________________
Air cleaner (A)
1. As the element (A) of the air cleaner employed
on this engine is a dry type, never apply oil to
it.
2. Open the evacuator valve once a week under
ordinary conditions-or daily when used in a
dusty place-to get rid of large particles of dust
and dirt.
3. Avoid touching the element except when
cleaning.
4. When dry dust adheres to the element, blow
compressed air from the inside turning the
element. Pressure of compressed air must
be under 7kgf/cm2 (100psi)
5. When carbon or oil adheres to the element,
soak the element in detergent for 30 minutes
then wash it several times in water, rinse with
clean water and dry it naturally. After the
element is fully dried, inspect inside of the
element with a light and check if it is damaged
or not. (referring to the instructions on the label
attached to the element.)
NOTE: Make sure the wing-head bolt for the element is tight enough. If it is loose, dust and dirt may be
sucked into the engine, causing premature engine wear with resulting loss of power.
8.6 ENGINE : EVERY 400 HRS ______________________________________________

head and fit locking ring.
