Instructions on fuel
and engine oil
1. Fuel
! Warning
Gasoline is inflammable and
explosive. When handling gasoline,
attention should be paid to prevent
burnt or accident.
In places where gasoline is
stored or handled, shutdown the
engine, do not smoke, and keep
away from naked flame or
spark.
Refueling should be made in a
well ventilated place. After
refueling, immediately clean off
any gasoline outside the fuel
tank.
Please #93 or #95
(GB17930-1999) unleaded gasoline.
This may prolong the service life of
spark plug.
Note!
If the engine produces ping
noise, it may be caused by using of
improper fuel. Replace with correct
fuel.
Ethanol gasoline
If ethanol gasoline is used,
please use #90 or higher conforming
to GB18351-2004. Do not use
methanol gasoline, even though it
may contain cosolvent and
anti-corrosion agent.
Note!
If ethanol gasoline is exposed to
water excessively, ethanol may be
separated, resulting in decrease of
gasoline octane number. Therefore,
the storage time should not be too
long.
Before using ethanol gasoline for
the first time, make a through
cleaning of the fuel supply system
and fuel tank.
Always buy a proper amount of
ethanol gasoline. Once there is a
poor fuel tank sealing or a long
storage time, moisture content may
increase, causing low octane number
and resulting in difficult ignition or
weak power.
2. Lubricant
(Please refer to Regular
Maintenance Table)
Use high quality 4-stroke
engine oil to prolong engine life.
Engine oil should be SE or SD
product in API classification. Engine
oil of proper viscosity should be
used according to local air
temperature. There are three
viscosity levels suitable for the
engine, namely, SAE15W-40,
SAE10W-30 and SAE5W-30. Refer
to the figure below:
