Chapter 1 BASIC SAFETY PRECAUTIONS
Never Operate the Engine
Under Over Load
If overload symptoms such as black exhaust smoke is
observed, reduce the load immediately and assure the
proper output and load.
Overloading causes not only high fuel consumption
but also excessive carbon deposits. Carbon deposits
cause various problems and will shorten the service
life of the engine.
Do Not Operate Engine Contin-
uously Under Low Load
When operating the engine with less than 30 % of
rated load, limit each operation to an hour. Prolonged
warm-up operation causes carbon build-up in the cyl-
inders that leads to incomplete combustion. Operate
the engine with a 30 % of rated load or more for over 5
minutes to prevent carbon build-up after one hour
continuous operation is conducted.
Protection of Engine Against
Water Entry
Do not allow rainwater, etc. to enter the engine
through the air inlet or exhaust ports.
Do not wash the engine while it is running. Cleaning
fluid (water) can be sucked into the engine.
Starting the engine with water inside the combustion
chambers can cause the water hammer action which
may result in internal engine damage and serious
accidents.
Conduct Proper Maintenance of
Air Cleaner or Pre-cleaner
Pay attention to the Air Cleaner or Pre-cleaner main-
tenance.
ΠNever service the air cleaner while the engine is run-
ning.The turbocharger may suck particles of foreign
materials into the engine and could result in serious
accidents.
Œ
Remove the air cleaner slowly to prevent foreign ma-
terials accumulated on the element from falling off. Af-
ter removing the air cleaner or pre-cleaner,
immediately cover the opening (inlet port of air clean-
er; port in body for pre-cleaner) with plastic sheet or
similar means to prevent foreign materials from enter-
ing the engine.
ΠWash pre-cleaner periodically. The pre-cleaner clog-
ging can cause insufficient intake air or increase of the
exhaust temperature.
ΠIf the engine is equipped with a dust indicator, con-
duct maintenance when a warning sign of a clogging
appears.
Use of Tools Optimum for Each
Work
Always keep in mind to select most appropriate tools
for the work to be performed and use them correctly. If
tool is damaged, replace it with new one.
Avoidance of Prolonged Start-
ing Operation
Do not use the starter for more than 10 seconds at a
time. If the engine does not start, wait for at least 1
minute before cranking again.
Continuous operation of the starter will drain the bat-
tery power or cause the starter to seize.
