* There may be some differences in operation depending on shapes of screws and the
workpieces used.
Conduct a test before actual driving.
Soft-grip handle
The handle is widely covered with soft-touch elastomer (rubber-like soft resin). It is slip-resistant and
securely fits in the palm of a hand even if the gripping hand sweats.
Safe and secure lithium-ion batteries
(Types BSL 1415 and BSL 1815)
The new 1.5 Ah Types BSL 1415 and BSL 1815 Lithium-ion Batteries were developed for light-duty work.
Both batteries are equipped with an overdischarge protection circuit, overload protection circuit, overheat
protection circuit and voltage monitoring circuit for each cell to prevent reduced battery service life due to
overdischarge (overuse) or overcharge (excessive charging). These protection circuits make it possible to
safely use the batteries.
Precautions on using the Types BSL 1415 and BSL 1815 Lithium-ion Batteries
The Types BSL 1415 and BSL 1815 Lithium-ion Batteries are both equipped with a protective function that
automatically stops output to prolong battery service life. The motor may stop automatically in any of cases
(1), (2) and (3) below, even if the switch is held down during operation. This is due to activation of the
protective function. The batteries are not faulty.
