Cleaning Air Cleaner Element
To avoid personal injury:
A
Be sure to stop the engine and remove the key
before cleaning air cleaner element.
1. Remove the air cleaner cover and the element.
(1) Undo the hook
(2) Turn the cover clockwise and detach it.
2. Clean the 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 205kPa (2.1kgf/
).
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.
(referring to the instructions on the label
attached to the case.)
3. Replace air cleaner element:
Once yearly or after every sixth cleaning, 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
Align the arrow marks when reinstalling the cover. If
the cover is improperly fitted, dust passes by the baffle
and directly adheres to the element.
C 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
Checking Fuel Lines and Fuel Filter
To avoid personal injury:
A Stop the engine and remove the key before
checking fuel lines and fuel filter.
A
Check the fuel lines periodically. The fuel lines
are subject to wear and aging. Fuel may leak
out onto the running engine, causing a fire.
The fuel line connections should be checked annually or
every 100 service hours, whichever occurs first.
1. The fuel line is made of rubber and ages regardless of
service period.
2. After inspection, if the fuel line and clamps are found
damaged or deteriorated, replace them.
3. Check fuel filter, if it is clogged by debris or
contaminated by water, replace it.
A
When the fuel line is disconnected for maintenance or
repair, plug both ends of the fuel line with a clean plug
of suitable size to prevent dust and dirt from entering.
Particular care must be taken in order to avoid dust
and dirt getting into the fuel system. Entrance of dust
and dirt causes malfunction of the fuel pump.
