BFuel
CAUTION
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
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
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.)
BColor 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.
BImmediately stop the engine if;
A The engine suddenly slows down or accelerates.
A Unusual noises are suddenly appear.
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
CAUTION
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.

OPERATING THE ENGINE
BHow 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.
BRemedies
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 then other parts and replace
parts as needed.
PRECAUTIONS ON GENERATOR-
EQUIPPED ENGINE
CAUTION
To avoid personal injury:
If the engine is kept running under no
load or light load (load factor below
30%), unburnt fuel or carbon builds up in
the exhaust system. As a result, the
engine may get damaged or cause a fire.
Run the engine under enough load at
regular intervals to remove unburnt
fuel and carbon deposits.
Before doing the load operation,
A
make
sure
flammable around the engine.
A Do not put a load all at once on the
engine, but gradually.
If by any chance, spark rises out of
A
the muffler outlet, DO NOT GET
THE ENGINE UNLOADED, BUT
INTERRUPT IT IMMEDIATELY.
