fully until the red indicator cannot be seen. If not,
it may accidentally fall out of the tool, causing injury to
you or someone around you.
CAUTION: Do not install the battery cartridge
forcibly. If the cartridge does not slide in easily, it is
not being inserted correctly.
Tool / battery protection system
The tool is equipped with a tool/battery protection sys-
tem. This system automatically cuts off power to the
motor to extend tool and battery life. The tool will auto-
matically stop during operation if the tool or battery is
placed under one of the following conditions:
Overload protection
When the battery is operated in a manner that causes
it to draw an abnormally high current, the tool automat-
ically stops without any indication. In this situation, turn
the tool off and stop the application that caused the tool
to become overloaded. Then turn the tool on to restart.
Overheat protection
When the tool/battery is overheated, the tool stops
automatically. In this situation, let the tool/battery cool
before turning the tool on again.
Overdischarge protection
When the battery capacity is not enough, the tool stops
automatically. In this case, remove the battery from the
tool and charge the battery.

Checking the remaining battery
capacity (BL1460A)
► Fig.2: 1. Indicator lamps 2. Check button
NOTE: Depending on the conditions of use and the
ambient temperature, the indication may differ slightly
from the actual capacity.
When charging
When the charging begins, the rst (far left) indicating
lamp begins to blink. Then, as charging proceeds, the
other lamps light, one after the other, to indicate the
battery capacity.
NOTE: If the indicator lamp does not turn on or blink
when charging, the battery may be faulty. In this case,
ask your local service center.
When using
When the tool is switched on, the lamps will light to
indicate the remaining battery capacity. When the tool is
switched off, the light goes out after approx. 5 seconds.
When pushing the check button with the tool switched
off, the indicator lamps turn on for approx. 5 seconds to
show battery capacity.
If the orange lamp blinks, the tool stops because of little
remaining battery capacity (Auto-stop mechanism).
Charge the battery cartridge or use a charged battery
cartridge at this time.
When the tool is used with the battery that has not been
used for a long time and is switched on, no lamps may
light up. The tool stops because of little remaining bat-
tery capacity at this time. Charge the battery properly.
