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".
CAUTION:
If cannot restart the engine, check the engine oil level first 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 finding troubles and troubleshooting, depress the
breaker button to tun the breaker on.
Operating on mountainous areas
On mountainous areas, the standard mixture ratio is relatively too big so the engine performance may be impaired while the fuel consumption may increase,
besides, too big mixture ratio will pollute the spark plug to result in starting the engine difficultly. This' problern can be solved by amending the carburetor
technological status. If always using on highlands with a height above sea level of 1800 meters, ask your dealer for doing the job. However, the engine power
will decrease by about 3.5% with every 305 meters up in height.
CAUTION : Amended engine applicable to highlands may be damaged seriously in area below altitude of 1800 meters for overheating, because its mixture
ratio is too small tor operation in low altitude area. In the case, ask your dealer to recover the engine to its normal technical status.
STOP
In emergency, push the engine switch to "OFF" to stall the engine; to stop it in normal, do
as follows:
1. Push right the throttle lever to the bottom.
2. Push the engine switch to "OFF".
3. Set the fuel cock to "OFF".
CAUTION: Sudden stopping at high speed under heavy load is forbidden, otherwise damage will result.
Exhaust control system
With the engine running, carbon monoxibe, 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. The company decreases the exhaust
emissions by introducing poor-fuel carburetors and other devices into the engine to solve the problem. 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 aintenance 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. Replacement of Parts
We recommend that you should choose such parts which are manufactured by the company or equivalent to these in quality as replacement ones. Replacement
without so high quality as the original ay the exhaust conbrol systan in effectiveness.
3.Modifying
Modifying the exhaust control system may make actual exhaust emissions exceeding statutory limit values. Illegal modifications as such:
a) Dismantle or modify any part of air intake or exhaust system.
b) Modify or take off speed - adjusting connection device or speed adjustment device to result in the engine's running beyond the set parameters.
