Overheat protection
When the machine is overheated, the machine stops automati-
cally and the main power lamp lights up in red. In this case, let the
machine and battery cool before turning the machine on again.
Overdischarge protection
When the battery capacity is not enough, the main power
lamp and the corresponding battery indicator blink in red.
In this case, switch the battery cartridges, or change the
battery cartridges to fully charged ones, or remove the
battery cartridges from the machine and charge them.
NOTE: The main power lamp blinks in red when the
battery is overheated.
Protections against other causes
NOTICE:
The main power lamp blinks in green
and red alternately when the abnormality occurs
in the machine. In this case, refer to the section
for troubleshooting.
Protection system is also designed for other causes that could
damage the machine and allows the machine to stop automati-
cally. Take all the following steps to clear the causes, when the
machine has been brought to a temporary halt or stop in operation.
1.
Turn the machine off, and then turn it on again to restart.
2.
Charge the battery(ies) or replace it/them with
recharged battery(ies).
3.
Let the machine and battery(ies) cool down.
NOTICE:
If no improvement can be found or
the machine stops due to a cause not described
above, refer to the section for troubleshooting.
Indicating the remaining battery
capacity
CAUTION:
Before checking the remaining
battery capacities or switching the battery car-
tridge, be sure to stop the machine.
CAUTION:
When the battery capacity
becomes low, a short beep sound is emitted. In
this case, lock the brake lever, and then switch
the battery cartridges to charged ones or charge
the battery cartridges. If you continue to operate the
machine at low battery capacity and the remaining
battery capacity runs out, a long beep sound is emit-
ted and the machine automatically stops and this may
cause an accident or injury.
CAUTION:
If the beep sound is emitted while
operating on slopes, move the machine to a safe
place, lock the brake lever, and then switch the
battery cartridges to charged ones or charge the
battery cartridges.
CAUTION:
If the load is large and the beep
sound is emitted while operating on slopes, lock
the brake lever and pay attention to safety and
switch the battery cartridges to charged ones.
Move the machine to a safe place and lock the
brake lever. Reduce the load before operating the
machine again. For details, refer to the section for
troubleshooting on slope.

NOTE: If you continue to pull the switch trigger even
if you hear the short beep sound, the machine stops
automatically. After the machine stops automatically,
the beep sound continues and the support brake
(electric brake) is enabled. To cancel the beep sound
and release the support brake, pull the brake lever
and release the switch trigger. Do not push the
machine forcibly without releasing the support brake.
NOTE: You can check the remaining battery capacity
even if the lock key is not inserted.
NOTE: The battery indicators for remaining battery
capacity is just for a reference. The actual bat-
tery capacity may differ depending on the usage
conditions.
