8 Bleeding fuel system
Be careful to avoid fuel spilling on the
engine fun belt, rubber vibration insulator,
hose and other parts, and clean them with
water if any to avoid fire hazard.
Air may enter the fuel system and result in stalling of
the engine after fuel is used up.
1. Tighten the fuel tank cap after refueling.
2. Put the key switch to “ON”, wait 20-30 seconds till air
in the fuel pipeline is exhausted, and then move the
switch to “Start” to start up the engine.
9. Cleaning and replacing the air
filter
The air filter can remove dust in the air to prevent wear
of parts inside the engine. As lots of dust may be
generated during harvesting, the filter should be
cleaned frequently (every day) and replaced every 400
hours.

) to purge inside
the element.
[Precaution]
Keep the filter element dry.
Do not clean the filter element with water or oil.
●
Engine oil may be consumed and
failures be caused if the filter element
is blocked.
●
Be careful to prevent deformation of
the element during cleaning. Otherwise,
dust may enter and cause abnormal
wear of the engine piston and cylinder.
10. Cleaning the engine dust
protector
The air entry is designed for suction of cooling air. It
may be accumulated with dust, thus should be cleaned
with a soft brush after the engine is stopped. Open the
engine room cover, and remove dust on it.
The screen of hydraulic oil cooler and radiator exposed
to dust should also be cleaned.
