GLISH
REVERSED ENGINE REVOLUTION AND
REMEDIES
To avoid personal injury or death:
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.
EMISSION CONTROL SYSTEM
A
Operate, use and maintain the engine, including the
emission control system in accordance with the
instructions provided to the end users, so that the
engine’s emissions performance is kept within the
requirements applicable to the engine's category.
A Do not deliberately tamper, or misuse, the engine
emission control system, especially with regard to
deactivating or not maintaining an exhaust gas
recirculation (EGR) system or a reagent dosing
system.
A When a warning indicator lights up, the engine is
experiencing trouble, which may also cause problems
in the emission control system. Take prompt action
and rectify any incorrect operation, use, or
maintenance of the emission control system in
accordance with the rectification measures. (See
"TROUBLESHOOTING" or, where applicable,
"OPERATOR WARNING AND INDUCEMENT".
PRECAUTIONS ON GENERATOR-
EQUIPPED ENGINE
To avoid personal injury or death:
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.
