5-1. Selling Point Descriptions
Selling points of the Models WH 14DSL and WR 14DSL:
(1) Equipped with the lightweight and high-capacity (3.0 Ah) lithium-ion battery
• Thanks to the adoption of the lithium-ion batteries, the Models WH 14DSL and WR 14DSL are
substantially lighter than the current models equipped with Ni-MH batteries.

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
(a)
or (b)
even if the switch is depressed continuously during
operation. This is because the protective function is activated. The battery is not faulty.
(a)
The motor automatically stops when the remaining battery level is low (when the battery
voltage is decreased to about 8 V (Type BSL 1430)). Charge the battery immediately in
such case.
(b)
The motor may stop if the Model WH 14DSL/WR 14DSL is overloaded. In such case,
release the switch and eliminate the cause of the overload problem. Then the Model
WH 14DSL/WR 14DSL will be operable.
Please instruct the customers on the above precautions.
(2) Switchable impact rate between save mode and power mode
The impact rate is switchable between two modes (save mode and power mode) according to
applications. Put the Model WH 14DSL/WR 14DSL into the save mode for tightening machine
screws into soft materials or put into the power mode for tightening long screws into hard
materials. These models are very convenient because the impact rate can be adjusted
according to the working conditions.
* Precautions for use in the save mode
If the Model WH 14DSL/WR 14DSL is operated continuously in the save mode, the temperature
of the electronic circuit modules in the switch may rise and it may result in burnout.
