Section 4 – BATTERY HANDLING Mini-Crawler Crane M A E D A
4-86 9/2020 MC285CB-3
If smoke is emitted or fire occurs, extinguish
any fire and cool down the battery
immediately. Carbon dioxide gas fire
extinguishers, powder fire extinguishers, or
dry sand should be used to extinguish fire.
Do not use different battery types mixed
together. Always use the specified battery
type.
CAUTION: Note the following precautions
when using the battery:
• Do not drop the battery or subject it to
strong impact. Otherwise there is a risk of
accidents or failure if the exterior or interior
becomes damaged.
Never use a battery after it has been
subjected to impact. Even if it appears
normal, it may be damaged internally.
• Use in locations where it will not be
splashed with water or other fluids, or use in
suitably waterproofed conditions.
• Never use high-pressure water jet cleaning
when cleaning the machine.
• Leaving the machine in an
emergency-stopped state will drain the
battery. Be sure to turn the starter switch to
“OFF” when the machine is stopped for
extended periods.
• Take care when using the battery at
elevations above 1,000 m, as its cooling
performance will be reduced.
Action When the Battery Is
Drained
DANGER! If the machine has just come to a
stop due to low battery level, it can be
operated for a short time by turning the
override switch to “ON”. Note, however, that
this disables its safety mechanisms, so this
procedure must be used only during
emergencies, such as for stowing operations.
If the machine has stopped due to low battery
level, one of the following measures should be
taken to prevent over-discharging or reducing
the battery performance:
• Recharge the battery promptly, preferably
within an hour.
• If recharging is not practical, use the
disconnect switch to prevent battery
consumption.
The battery should be charged within a week,
as it will become defective if it is drained to
an over-discharge state.
