Yanmar 4JH3-TE Operation Manual page 7

Alcohol
• Never operate the engine while you are under the influence of alcohol or
when you are ill or feel unwell as this results in accidents.
Safety Precautions for Inspection
Battery Fluid
• Battery fluid is diluted sulfuric acid. It can blind you if it gets in your eyes, or
burn your skin. Keep the fluid away from your body. Wash it off immedi-
ately with a large quantity of fresh water if you get any on you.
Fire due to Electric Short-Circuits
• Always turn off the battery switch or detach the earth cable (-) before
inspecting the electrical system. Failure to do so could cause short-circuit-
ing and fires.
Precautions for Moving Parts
• Stoop the engine before you service it. If you must inspect while the engine
is operating, never touch moving parts. Keep your body and clothing well
clear of all moving parts as this could result in injury.
Precautions for Removing Hot Oil and Water to Prevent Burns
• If extracting oil from the engine while it is still hot, do not let the oil splash on
you.
• Wait until the temperature has dropped before removing cooling water from
the engine to avoid getting scalded.
NOTICE:
Do not alter the diesel engine.
Rebuilding the engine or altering parts to increase the speed or the amount of fuel dis-
charged, etc. will make operation unsafe, and result in damage and shortening of engine
life.
NOTICE:
Disposal of waste materials
• Put oil or liquids to be disposed in a container. Never dispose of waste oil or other fluids
outside, in a sewer, river, or the sea.
• Treat waste materials safely observing all regulations and laws. Ask a waste recovery
company to collect and dispose of it.
