Tips for maintaining maximum
battery life
Charge the battery cartridge before completely dis-
1.
charged. Always stop tool operation and charge the
battery cartridge when you notice less tool power.
Never recharge a fully charged battery cartridge.
2.
Overcharging shortens the battery service life.
3. Charge the battery cartridge with room tempera-
ture at 10 °C - 40 °C (50 °F - 104 °F). Let a hot
battery cartridge cool down before charging it.
4. Charge the battery cartridge if you do not use
it for a long period (more than six months).
FUNCTIONAL
DESCRIPTION
CAUTION:
Always be sure that the tool is
switched off and the battery cartridge is removed
before adjusting or checking function on the tool.
Installing or removing battery
cartridge
CAUTION:
Always switch off the tool before
installing or removing of the battery cartridge.
CAUTION:
Hold the tool and the battery car-
tridge firmly when installing or removing battery
cartridge. Failure to hold the tool and the battery
cartridge firmly may cause them to slip off your hands
and result in damage to the tool and battery cartridge
and a personal injury.
► Fig.1: 1. Red indicator 2. Button 3. Battery cartridge
To remove the battery cartridge, slide it from the tool
while sliding the button on the front of the cartridge.
To install the battery cartridge, align the tongue on the
battery cartridge with the groove in the housing and slip
it into place. Insert it all the way until it locks in place
with a little click. If you can see the red indicator on the
upper side of the button, it is not locked completely.
CAUTION:
Always install the battery cartridge
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.
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 first (far left) indicating
lamp begins to flicker. 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 flicker
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 flickers, 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.
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 tool/battery is operated in a manner that
causes it to draw an abnormally high current, the tool
stops automatically. 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.
Switch action
WARNING:
Before installing the battery car-
tridge into the tool, always check to see that the
switch trigger actuates properly and returns to
the "OFF" position when released.
To start the tool, simply pull the switch trigger. Release
the switch trigger to stop.

NOTE: For approximately one second after fastening,
the tool does not work even with the switch pulled.
