Every 250 Hours Of Operation - Yanmar 2TNV70 Service Manual

Periodic Maintenance Procedures
• When the amount of fluid nears the lower limit
(Figure 5-8, (1)), fill with distilled water
(Figure 5-8, (2)) so it is at the upper limit
(Figure 5-8, (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 5°F (-15°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.
