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 AND INSTALLATION OF BATTERY
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.
