AIR CLEANER
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 element every year or every 6 cleanings.
A Make sure the wing bolt 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.
B Evacuator valve
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.
B For the air cleaner with a dust cup
(optional)
Remove and clean out the dust cup before it becomes
half full with dust; usually once a week, or even every day
if the working surroundings are dusty.
Install the air cleaner dust cup with "TOP" indicated on the
rear of the cup in the up position. (However, it may be
installed in either direction when the cover is placed at the
lower part.)
A If the dust cup is mounted incorrectly, dust or dirt does
not collect in the cup, and direct attachments of the
dust to the element will cause its lifetime to shorten to
a great extent.
