PRECAUTIONS FOR CHECK AND MAINTENANCE
TURN BATTERY DISCONNECT SWITCH TO OFF POSITION
In the following cases, turn the starting switch to OFF position and check that the system operating lamp is off.

If you check and handle battery without turning battery disconnect switch to OFF position, serious personal in-
jury or death by such as an electric shock may occur.
•
When storing the machine for a long time (more than 1 month)
•
When repairing the electrical system
•
When performing electric welding
•
When handling the battery
•
When replacing the fuse, etc.
PRECAUTIONS FOR WELDING
Welding operations must always be performed by a qualified welder and in a place equipped with proper equip-
ment. There is a hazard of gas, fire, or electric shock when performing welding, so never allow any unqualified
person to perform welding.
HANDLE BATTERY
Before inspecting or handling the battery, turn the key in the starting switch to OFF position and check that the
system operating lamp is off. Then set the battery disconnect switch to OFF position and remove the switch key.
Danger of battery exploding
When the battery is being charged, flammable hydrogen gas is generated and may explode. In addition, the bat-
tery electrolyte includes dilute sulphuric acid. Any mistake in handling may cause serious personal injury, explo-
sion, or fire, so always observe the following.
•
Do not use or charge the battery if the battery electrolyte is below LOWER LEVEL mark. This may cause
an explosion. Always perform periodic inspection of the battery electrolyte level, and add purified water
(such as a commercial battery fluid) to UPPER LEVEL mark.
•
Do not use a dry wipe to clean the battery. A wet wipe will prevent fire or explosion from static electricity.
•
Do not smoke or bring any open flame close to the battery.
•
Hydrogen gas is generated when the battery is being
charged, so remove the battery from the machine, take it
to a well-ventilated place, remove the battery caps, then
perform the charging.
•
After charging, tighten the battery caps securely.
