Hitachi RB 14DSL Technical Data And Service Manual page 4

Applicable to slide-type 14.4 V lithium-ion battery
The Type BSL 1430 lithium-ion battery is equipped with the overdischarge protection circuit, overload
protection circuit, and voltage monitoring circuit for each cell to prevent shortening of the battery life due to
overdischarge (overuse) or overcharge (excessive charging) of the battery. The number of
charging/discharging is about 1,500.
Precautions for use of the Type BSL 1430 lithium-ion battery
The Type BSL 1430 lithium-ion battery is equipped with a protective function that automatically stops
output to extend the battery life. The motor may stop automatically in either of the following case 1 or 2
even if the switch is depressed continuously during operation. This is because the protective function is
activated. The battery is not faulty.
1 The motor automatically stops when the remaining battery level is low (when the battery voltage is
decreased to about 8 V). Charge the battery immediately in such case.
2 The motor may stop if the Model RB 14DSL is overloaded. In such case, release the switch and eliminate
the cause of the overload problem. Then the Model RB 14DSL will be operable.
Please instruct the customers on the above precautions.
