•Fuel
A
CAUTION
To
avoid personal
injury:
• 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
~
medical
doctor
at
once.
This
fluid
can produce
gangrene
or
a severe allergic reaction.
• 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).
•Color
of
exhaust
While the engine is run within the rated output range:
• The color
of
exhaust remains colorless.
•
If
the output slightly exceeds the rated level, exhaust
may become a little colored with the output level kept
constant.
•
If
the engine is run continuously with dark exhaust
emission, it may lead to trouble.
•Immediately
stop
the
engine
if;
• The engine suddenly slow down or accelerates.
• Unusual noises suddenly appear.
• Exhaust fumes suddenly become very dark.
• The oil pressure lamp or the water temperature alarm
lamp lights up.
OPERATING THE ENGINE 7
RE
VERSED
ENGINE
REVOLUTION
AND
REMEDIES
A
CAUT
I
ON
To
avoid personal
injury:
• Reversed engine operation can
make
the
machine reverse
and
run
it
backwards.
It
may
lead
to
serious trouble.
• 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.
•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
ga ~
will
come out
of
the air cleaner.
3.
A louder knocki
ng
sound will be heard when the
engine starts running backwards.
•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.
