over the fuel ller shoulder.
1) Gasoline is extremely flammable and is explosive under certain
conditions.
2) Refueling in a well-ventilation area with the engine stopped. Do
not smoke and do not allow flames or sparks in the area where
gasoline is stored or where the fuel tank is refueled.
3) Do not overll the fuel tank (there should be no fuel in the lling
neck). After refueling, make sure the fuel tank cap is set back
securely.
4) Be careful not to spill fuel when refueling. Spilled fuel or fuel
vapor may ignite. If any fuel is spilled, make sure the area is dry
before starting the engine.
5) Avoid repeated or prolonged contact with skin or breathing of fuel
vapor. Keep out of reach of children.

when refueling. Any damage due to oil spilling is not within valid
warranty.
"Light knocking" or "spark exploding" sound can be hear when the
engine overloading. It is normal. Do not be worry about that.
If " knocking" or "spark exploding" sound occur at a steady speed
under normal load, change brand of gasoline; if such phenomena still
happen, consult your dealer for help, otherwise the engine may be
damaged.
When the engine is running, continuously "Knocking" or "spark
exploding" sound occurring will damage engine.
"Knocking" or "spark exploding" sound from misusing will not be
within the valid warranty.

run at required velocity.
ENGINE OIL ALARM
The engine oil alarm is designed to function when the engine oil in the
crankcase is insufficient. Lack of engine oil may damage the engine.
Once oil level in the crankcase is too low, the engine oil alarm will stall
the engine automatically to make it free of damage while the engine
switch is still at “ON”.

RUNNING THE ENGINE
If cannot restart the engine, check the engine oil level rst before go
to other check items.
BREAKER (Electric-start type)
The breaker will cut off automatically to protect the charging circuit of
the battery in the case that short circuit or incorrect connection of the
battery poles occurs.
The green indicator in the breaker will jump out with the circuit cutting
off. After nding troubles and troubleshooting, depress the breaker button
to turn the breaker on.
HIGH ALTITUDE OPERATION
At high altitude, the standard air-fuel mixture will be too rich.
Performance will decrease and fuel consumption will increase. A very
rich mixture will also foul the spark plug and cause hard starting. High
altitude performance can be improved by specific modifications to the
carburetor. If you always operate you trimmer at altitudes above 1000
meters, have your servicing dealer perform this.
Modified engine applicable to altitude may be damaged seriously
in area below altitude of 1000 meters for overheating, because its
mixture ratio is too small for operation in low altitude area. When
the carburetor has been modified for high altitude, operation the
air – fuel mixture will be to lean for low altitude use. Operation at
altitudes below 1000 meters with a modified carburetor may cause
the engine to overheat and result in serious engine damage.

EXHAUST CONTROL SYSTEM
VII. EXHAUST CONTROL SYSTEM
With the engine running, carbon monoxide, oxide of nitrogen and
hydrocarbon will produce, and in certain conditions, oxide of nitrogen
and hydrocarbon will react chemically each other to make smoke while
carbon monoxide is toxic, so exhaust control of them is very important.
To keep the exhaust of your engine with in the standard exhaust emission,
pay attention to the following:
1. Maintenance
Maintain the engine periodically in accordance with the maintenance
schedule in the manual. The maintenance schedule is made out on the
base of normal use in normal conditions, if using under heavy load, dusty
or wet circumstances or in high temperature, service of the engine should
be done more often.
2. Problems affecting exhaust emissions
1) Difcult starting or difcult stopping.
2) Unstable idling speed.
3) Give off black smoke or consume fuel too much
4) Poor ignition sparks or re back.
5) Too early ignition.
Once you nd any of above problems, contact your dealer for help.
