PERIODIC MAINTENANCE

Figure 1
• When the amount of fluid nears the lower limit
(Figure 1, (1)), fill with distilled water
(Figure 1, (2)) so it is at the upper limit
(Figure 1, (3)). If operation continues with
insufficient battery fluid, the battery life is
shortened, and the battery may overheat and
explode. During the summer, check the fluid
level more often than specified.
• If the engine cranking speed is so slow that
the engine does not start, recharge the
battery.
• If the engine still will not start after charging,
have your authorized Yanmar industrial
engine dealer or distributor check the battery
and the engine's starting system.
If operating the machine where the ambient
temperature could drop to -10°C or less, remove
the battery from the machine at the end of the
day. Store the battery in a warm place until the
next use. This will help start the engine easily at
low ambient temperatures.
Check Battery Indicator (If
Equipped)
Visually check the battery indicator (if equipped)
and any other indicator provided by the driven
machine manufacturer. See Indicators and
Controls – Electric Starter on page 17.

Check Engine Oil Level
CAUTION
• Only use the engine oil specified.
Other engine oils may affect warranty
coverage, cause internal engine
components to seize, or shorten
engine life.
• Prevent dirt and debris from
contaminating the engine oil. Carefully
clean the oil cap / dipstick and the
surrounding area before you remove
the cap.
• NEVER mix different types of engine
oil. This may adversely affect the
lubricating properties of the engine oil.
• NEVER overfill. Overfilling may result
in white exhaust smoke, engine
overspeed or internal damage.
CAUTION
Be environmentally responsible. Follow
these procedures for hazardous waste
disposal. Failure to follow these
procedures may seriously harm the
environment.
• Follow the guidelines of the
governmental agency for the proper
disposal of hazardous materials such
as engine oil, diesel fuel and engine
coolant. Consult the local authorities
or reclamation facility.
• NEVER dispose of hazardous
materials irresponsibly by dumping
them into a sewer, on the ground or
into ground water or waterways.
Before you operate the engine check the engine
oil level. See Checking Engine Oil on page 28.
