BFuel
To avoid personal injury:
Check of the fuel injection pipes
A Using a cardboard or a thin wooden
sheet, check to see if there is any
high-pressure oil leak. Do not touch
any high-pressure
directly with your hand and body.
If you are directly exposed to high-
pressure gushing oil, immediately
seek medical care. If such oil
penetrates your skin, get the oil
removed within
because otherwise the skin may
develop into gangrene.
Be careful not to empty the fuel tank. Otherwise air may
enter the fuel system, requiring fuel system bleeding.
(See "FUEL" in "MAINTENANCE" 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 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
make exhaust gas gush out into the
intake side and ignite the air cleaner;
It could catch fire.

OPERATING THE ENGINE
Reversed engine revolution must be stopped immediately
since engine oil circulation is cut quickly, leading to
serious trouble.
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.
(When the engine is not equipped with the stop lever,
set the speed control lever to the "STOP" position or
the key switch to the "OFF" (SWITCHED OFF)
position.)
2. After stopping the engine, check the air cleaner, intake
rubber tube and other parts, and then replace parts as
needed.
PRECAUTIONS ON GENERATOR-
EQUIPPED ENGINE
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.
A Before doing the load operation,
make sure
flammable around the engine.
A Do not put a load all at once on the
engine, but gradually.
A If by any chance, spark rises out of
the muffler outlet, DO NOT GET THE
ENGINE UNLOADED,
INTERRUPT IT IMMEDIATELY.
