5.2 PRECAUTIONS DURING MAINTENANCE
CAUTIONS DURING WELDING REPAIR
Conduct welding operation in a location with good facility, and, only authorized personnel are permitted
to be engaged in the welding work.
Unauthorized personnel are strictly prohibited since risks such as gas generation, fire and electrical
shock are present when welding.
CAUTIONS WHEN HANDLING BATTERY
For inspecting and handling the battery, turn the starter switch to
the “OFF” position and disconnect the power supply circuit to
prevent unexpected startup during servicing.
Because the battery produces hydrogen gas, sparks around the
battery can cause an explosion.
Moreover, the battery solution contains diluted sulfuric acid. Wrong
handling of it may cause a bodily accident, explosion and fire, and
therefore always observe the following precautions:
• AVOIDING THE RISK OF BATTERY EXPLOSION
• If the battery fluid level decreases to the LOWER LEVEL or
further below, do not use the battery or recharge it. Otherwise,
an explosion may occur.
Never fail to conduct the regular inspection of battery fluid level
and refill purified water (such as battery replenisher available
on the market) to the UPPER LEVEL.
• Do not smoke or use fire near the battery.
• During recharging the battery, it generates hydrogen gas that
is flammable.
Before recharging it, dismount if from the machine and conduct
the recharging in a well ventilated place. During the recharging
process, remove the battery cap.
• Securely tighten the battery cap afterwards.
•
WARNINGS CONCERNING DISCONNECTION OF THE
BATTERY CABLE DURING ENGINE OPERATION
Never remove the battery cable while the engine is running.
Surge voltages may be generated and destroy electronic
circuitry.
• AVOIDING THE RISK OF DILUTED SULFURIC ACID
• Always wear protective glasses and rubber gloves before
handling the battery.
• If the battery fluid enters your eyes, wash immediately with
water and see a doctor as soon as possible.
• If the battery fluid contacted clothing or skin, immediately wash
away by huge quantity of water.
• DISCONNECT BATTERY TERMINAL
Before starting the repair work of electric system and performing
a welding operation, first turn the starter switch OFF, wait for
about one minute, and then disconnect the battery terminals to
interrupt the flow of electric current.
• DANGER OF SPARKING
To prevent sparking, strictly observe the following precautions:
• Never allow such a metallic object as a tool to come in contact
with battery terminals. Do not leave tools or other object
around the battery.
• When removing the battery, be sure to disconnect the
grounding (
−
) end terminal first. Conversely for mounting it
again, first connect the positive (+) end terminal and fix the
grounding end (
−
) terminal finally.
• Fix the battery terminal securely.
• Fix the battery body to the specified position securely.
