BCleaning air cleaner element
Since the air cleaner employed on this engine is a dry
type, never apply oil to it.
1. Open the evacuator valve once a week under ordinary
conditions - or daily when used in a dusty place. This
will get rid of large particles of dust and dirt.
2. Wipe the inside air cleaner clean with cloth if it is dirty
or wet.
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 205 kPa
(2.1 kgf/cm , 30 psi).
5. Replace the primary element every year or every 6
cleanings.
If the primary element is stained heavily, replace it
soon. At this time, replace the secondary element too.
6. The secondary element should be removed only if it is
to be replaced.
7. To protect the engine, do not remove the secondary
element in servicing the primary element.
(A) Close
(1) Air cleaner body
(2) Dust cup
(3) Secondary element
(4) Primary element
(5) Evacuator valve
A Make sure the hooking clip for the element is tight
enough. If it is loose, dust and dirt may be sucked in,
wearing down the cylinder liner and piston ring earlier
and thereby resulting in poor power output.
A Do not overservice the air cleaner element.
Overservicing may cause dirt to enter the engine
causing premature wear. Use the dust indicator as a
guide on when to service.
C Cleaning primary air cleaner element
1. To clean the element, use clean dry compressed air
on the inside of the element.
Air pressure at the nozzle must not exceed 205 kPa
(2.1kgf/cm , 30psi).
Maintain reasonable distance between the nozzle and
the filter.
BAdjusting fan belt tension
To avoid personal injury or death:
A Be sure to stop the engine and
remove the key before checking the
belt tension.
A Be sure to reinstall the detached
safety shield after maintenance or
checking.
1. Stop the engine and remove the key.
2. Apply moderate thumb pressure to belt between the
pulleys.
3. If tension is incorrect, loosen the alternator mounting
bolts and, using a lever placed between the alternator
and the engine block, pull the alternator out until the
deflection of the belt falls within acceptable limits.
4. Replace fan belt if it is damaged.
