(5) Battery Cable Connection
Check the battery cable connections for looseness or cor-
rosion.
A loose cable connection will result in hard engine starting
or insufficient battery charge.
The battery cables must be tightened securely.
Never reverse "+" and "-" terminals when reconnecting
cables.
Even a short period of reverse connection will damage the
electrical parts.
(6) Battery Electrolyte Level
The amount of electrolyte in the batteries will be reduced
after repeated discharge and recharge.
Check the electrolyte for the level in the batteries, refill
with distilled water, if necessary.
The battery electrolyte level checking procedure will vary
with battery type. Follow the equipment manufacturer's
instructions.
CAUTION: Do not replenish with diluted sulfuric
acid in the daily service.
WARNING:
1) When inspecting the battery, be sure to stop the
engine.
2) As sulfuric acid is used as electrolyte, avoid
contact with eyes, hands, clothes, and metals. If it
gets in your eyes, flush with large amounts of
water at once. Then consult a physician immedi-
ately.
3) Since batteries produce hydrogen gas, do not
make a spark or use fire near the battery.
4) When handling metal objects near the batteries,
be sure not to contact the battery’s "+" terminal.
As the vehicle body is "-", it may cause a spark or
electrical shock.
5) When disconnecting the terminals, start with the
negative "-" terminal. When connecting them,
connect the negative "-" terminal last.

(2) Pre-heating Procedure
As an engine starting aid, pre-heating is required for cold
engine starting.
1. Turn the starter key clockwise to the “PRE-HEAT” posi-
tion in order to heat the glow plugs on the engine.
The pre-heating time varies depending on the types of
pre-heating system as follows:
