7 OPERATING THE ENGINE

B 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 "PERIODIC SERVICE" section.)
B Color of exhaust
While the engine is run within the rated output range:
A
The color of exhaust remains colorless.
A If the output slightly exceeds the rated level, exhaust
may become a little colored with the output level kept
constant.
A If the engine is run continuously with dark exhaust
emission, it may lead to trouble with the engine.
B Immediately stop the engine if;
A The engine suddenly slows down or accelerates.
A Unusual noises are suddenly heard.
A Exhaust fumes suddenly become very dark.
A The oil pressure lamp or the water temperature alarm
lamp lights up.
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 the "STOP"
position to stop the engine.
2. After stopping the engine, check the air cleaner, intake
rubber tube and other parts, and then replace parts as
needed.
