TROUBLESHOOTING

IF BATTERY IS DISCHARGED

It is dangerous to charge a battery when mounted on a machine. Make
sure that it is dismounted before charging.
When checking or handling the battery, stop the engine and turn the
starting switch key to the OFF position.
The battery generates hydrogen gas, so there is a hazard of explosion.
Do not bring lighted cigarettes near the battery, or do anything that will
cause sparks.
Battery electrolyte is dilute sulphuric acid, and it will attack your clothes
and skin. If it gets on your clothes or on your skin, immediately wash it
off with a large amount of water. If it gets in your eyes, wash it out with
fresh water and consult a doctor.
When handling batteries, always wear protective goggles and rubber
gloves.
When removing the battery, first disconnect the cable from the ground
(normally the negative (-) terminal). When installing, install the positive
(+) terminal first.
If a tool touches the positive terminal and the chassis, there is danger
that it will cause a spark, so be extremely careful.
If the terminals are loose, there is danger that the defective contact may
generate sparks that will cause an explosion.
When removing or installing the terminals, check which is the positive
(+) terminal and which is the negative (-) terminal.
REMOVAL, INSTALLATION OF BATTERY CABLE
Before removing the battery, remove the ground cable (normally connected to the negative (-) terminal).
If any tool touches between the positive terminal and the chassis, there is a hazard of sparks being generated.
When installing the battery, connect the ground cable last.
When replacing the battery, secure it with battery fitting.
