6.7.3 CautIOn FaCt OF eLeCtrIC wIrInG
Do not reverse connection the battery.
If reverse connecting the plus (+) and minus (-) of battery cable, the diode of alternator is damaged and
does not become charging. Also the starter coil burn out. Battery must be produced by correcting the
length of battery cable or by making the structure which prevents a reverse connection in order for not to
become the reverse connection.
Charging output voltage not use the control purpose.
The engine number of rotation and output voltage are not constant proportion. Therefore output voltage
forbids using the control purpose.
Use the specified V-belt.
Do not high-pressure cleaning using the high pressure washing machine.
If alternator does high-pressure cleaning, charging becomes defect due to insert water in brush.

aLternatOr
Use the battery which satisfied specification.
Starting performance of engine depend on capacity of battery. This battery capacity should be change
according to temperature condition and using condition in work machine. Consequently, select the battery
which satisfied specification and must use it.
Total wire resistance of battery cable(+,-) must be less than 2/1000Ω.
If total wire resistance is out of standard value, it is cause of breakdown and functional loss in starter.
If wire resistance of starter must be more than standard value.
Reciprocation wire total resistance between starter and key switch (Or power relay, safety relay: when
using) must be less than 5/100Ω.
Do not high pressure cleaning with high pressure washing machine.
Waterproof of starter is level which is no problem when pouring the water or rain usually. Consequently, do
not high pressure cleaning or be submerged.

Starter
Do not use excessive discharged battery (under 8V). Abnormal high voltage is generated when using it. As
a result, other electronic sub assembly is damaged. Excessive discharged battery uses after charging.
Do not separate the battery during the operation. If separating the battery during the operation, malfunction
the current limit and not control the output voltage. In this case, electronic sub assembly is damaged by
generating the continuous high voltage.
