Changing Engine Oil
To avoid personal injury:
A
Be sure to stop the engine and remove the key
before changing the oil.
A Allow engine to cool down sufficiently; oil can
be hot and may cause burns.
1. To change the used oil, remove the drain plug at the
bottom of the engine and drain the oil completely. The
used oil can be drained out more easily if the engine is
warm.
2. Fill with the new oil up to the upper notch on the
dipstick.
3. To check the oil level. Remove the dipstick, wipe it
clean, insert it and draw it out again. Check to see that
the oil level is between the two marks.
B Cleaning Air Cleaner Primary Element
1. Remove the air cleaner cover and primary element.
2. Clean the primary element:
(1) 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).
(2) When carbon or oil adheres to the element, soak
the element in detergent for 15 minutes then wash
it several times in water, rinse with clean water
and dry it naturally. After element is fully dried,
inspect inside of the element with a light and
check if it is damaged or not.
3. Replace air cleaner primary element:
Once yearly or every 1000 hours whichever comes
first.
A Check to see if the evacuator valve is blocked with
dust.
A
The air cleaner uses a dry element, never apply oil.
A
Do not run the engine with filter element removed.
A Be sure to refit the cover with the arrow (on the rear
of cover) upright. If the cover is improperly fitted,
evacuator valve will not function and dust will adhere
to the element.
A Do not touch the secondary element except in cases
where replacing is required.
C Evacuator Valve

conditions - or daily when used in a dusty place - to get rid
of large particles of dust and dirt.
(1) Drain plug
