SAFETY CAUTIONS
0 - 7
Caution Other considerations
●
Never alter or modify the engine
Altering or modifying the engine in any way will
nullify the warranty.
A modified engine may not only break but also lead
to injury.
●
Do not tamper with sealing
To help ensure trouble-free operation of the engine,
the fuel control link has been sealed to achieve the
correct fuel injection volume and engine speed. If
the sealed setting is tampered with, the following
will result and the correct functioning of the engine
is no longer guaranteed.
・
Sliding and rotating parts will wear faster.
・
Various parts will seize/become damaged.
・
The engine will consume more fuel and oil.
・
The governor and fuel injection volume go out of
balance, reducing the engine performance.
●
Daily and periodical inspection
Perform the daily and periodical inspection in
accordance with the Operation and Maintenance
Manual.
Failure to observe the instructions of the manual
may lead to many problems, and the various engine
parts may eventually fail, possibly causing a serious
accident.
●
Running-in period
A brand new engine requires a running-in period of
50 hours, during which never put the engine under
severe load. Otherwise, the service life of the engine
will be reduced.
●
Warming up the engine
Before starting work, warm up the engine by
running it at low idle for 5 to 10 minutes.
Warming up the engine will not only smoothen the
operation of various engine parts but also help
extend its service life. It also helps maximize the
performance and achieve economical running of the
engine.
Do not warm up the engine longer than necessary.
Doing so facilitates carbon deposit on the cylinders,
possibly leading to poor combustion.
●
Do not overload the engine
Do not continue to run the engine if it emits black
smoke.
Overloaded running of the engine (accompanied by
black smoke) not only consumes excessive fuel but
also facilitates carbon deposit and thus shortens the
service life of the engine.
●
Cooling down the engine
Before stopping the engine, cool it down (by running
it at low idle) for 5 to 6 minutes.
Stopping the engine suddenly while it is heavily
loaded will result in some areas of the engine
remaining extremely hot for a while, which is
detrimental to the long service life of an engine.
While the engine is being run at low idle for cooling,
check the engine for any problems.
●
Do not spill water onto the engine
Ensure that no rainwater etc. enters into the engine
from the exhaust or inlet manifold, or via any other
routes.
Do not run the engine while at the same time
washing it. Otherwise, cleaning fluid (water) may
be sucked into the engine.
If the engine is started with water trapped in the
combustion chambers, water hammering will result,
causing the engine to fail and possibly leading to a
serious accident.
