EN
GLISH
B
Oil pressure lamp
The lamp lights up to warn the operator that the engine oil
pressure has dropped below the prescribed level. If this
should happen during operation or should not go off even
after the engine is accelerated more than 1000rpm,
immediately stop the engine and check the following:
1. Engine oil level (See "Checking of engine oil level" in
"DAILY CHECKS" in "MAINTENANCE" section.)
B
Charge lamp
The charge lamp lights up to warn the operator the battery
charge is low during running or there is no alternator
output during running. It is normal to have the charge
lamp on when the key is on and engine is not running.
If the charge lamp is on during running, check the
following:
1. Cable broken
2. Poor connection at alternator terminal
3. Fan belt too loose or damaged
B
Fuel
To avoid personal injury or death:
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. Use
eye, face and hand protection such
as gloves and any necessary
appropriate additional personal
protective equipment and clothing.
Do not run the fuel tank level too low or completely out of
fuel. You may experience improper engine running and/
or a DTC (Diagnostic Trouble Code) error code may be
recorded in the Engine Control. Additionally, fuel system
bleeding may be necessary if air enters the fuel system.
(See "Checking of fuel level" in "DAILY CHECKS" in
"MAINTENANCE" section.)
B
Color of exhaust
White exhaust may come out. In most cases this is
caused by water vapor and not a problem. Such exhaust
disappears when the temperature rises up as specified.
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 lights up.
A
The engine warning lamp lights up.
A
Continuous large or abnormal quantities of white
smoke.
AIR FLOW SENSOR
B
Air cleaner-mounted type
A
Do not use any other air cleaner and element than
specified. Unspecified ones cause the air flow sensor
to malfunction and to lose its full performance.
B
Inlet hose pipe-mounted type
A
Be careful not to install the air flow sensor on the pipe
in the wrong direction.
A
Do not change the direction and insertion angle of the
hoses before and after the pipe. Wrong direction
causes the air flow sensor to malfunction and to lose
its full performance.
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 there is nothing
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, BUT
INTERRUPT IT IMMEDIATELY.
