TROUBLESHOOTING

DISCHARGED BATTERY WARNING ●

It is dangerous to charge the battery while it is still mounted on the machine. Always remove the battery before charging it.

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, wash it immediately off with large amounts 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 installing the terminals, install them tightly. When removing or installing the terminals, check which is the positive (+) terminal and which is the negative (–) terminal.

Green rust around the terminals is a cause of self-discharge of the battery. Polish the terminals with sandpaper. After removing the rust, coat the terminals thinly with grease before installing.

When removing, disconnect the cable from the ground terminal first.

When installing, connect the cable to the positive (+) terminal first.
