Fuel
To avoid personal injury:
A
Fluid escaping from pinholes may be invisible.
Do not use hands to search for suspected
leaks; Use a piece of cardboard or wood,
instead. If injured by escaping fluid, see a
medical doctor at once. This fluid can produce
gangrene or a severe allergic reaction.
A
Check any leaks from fuel pipes or fuel
injection pipes. Use eye protection when
checking for leaks.
Be careful not to empty the fuel tank. Otherwise air may
enter the fuel system, requiring fuel system bleeding.
(See "FUEL" in Maintenance Section).

REVERSED ENGINE REVOLUTION AND
REMEDIES
To avoid personal injury:
A
Reversed engine operation can make the
machine reverse and run it backwards. It may
lead to serious trouble.
A
Reversed engine operation may make exhaust
gas gush out into the intake side and ignite the
air cleaner; It could catch fire.
Reversed engine revolution must be stopped immediately
since engine oil circulation is cut quickly, leading to
serious trouble.
B
How to tell when the engine starts running
backwards
1. Lubricating oil pressure drops sharply. Oil pressure
warning light, if used, will light.
2. Since the intake and exhaust sides are reversed, the
sound of the engine changes, and exhaust gas will
come out of the air cleaner.
3. A louder knocking sound will be heard when the
engine starts running backwards.
B
Remedies
1. Immediately set the engine stop lever to "STOP"
position to stop the engine.
2. After stopping the engine, check the air cleaner, intake
rubber tube and other parts and replace parts as
needed.
