ABOUT BATTERY BCL1030M
1. Battery capacity indicator
<How to read the display>
Fig. 9-a When recharging, During pause
Fig. 9-b When using tools
(
: Lights,
: Goes out,
period),
: Blinks rapidly (0.5-second period))
(1) When recharging (Fig. 10)
The indication lamps will blink and indicate the
charging amount to the battery.
(2) During pause (Fig. 11)
The indication lamps will always blink and indicate
the remaining capacity of the battery.
(3) When using tools (Fig. 12)
When turning on the switch of the cordless tool, the
indication lamps will light and indicate the remaining
capacity of the battery. After three seconds or so
from releasing the switch, the indication lamps will
start blinking.
2. Protective function
In the following case 1 and case 2, the motor of the
cordless tool may stop (indication lamps are turned
off) during operation, however, this is not a sign of
failure, but is caused by activation of the protective
function.
(1) The motor stops when the remaining battery capacity
becomes low (battery voltage decreased to 6V). In
this case, recharge the battery promptly.
(2) The motor may stop when the cordless tool is
overloaded. In this case, release the switch and
eliminate the cause of the overload. After that, you
can use the tool again.
3. Indication of trouble (Fig. 13)
When the indication lamps blink rapidly (0.5-second
period), it may suggest a battery failure. Please take
the battery to the dealer you purchased from.
4. How to determine the battery usage life
When the operating time of the battery becomes
significantly short after correctly recharging the
battery, it may indicate the end of the battery life and
we recommend you to purchase a new battery.
NOTE:
If left unused for a long period, the battery may
become too weak to light up or blink the indication
lamps used to show the remaining power. The lamps
will light back up or blink once the battery is
recharged.
Hints on how to make the battery last
(1) Recharge the Battery Before it Becomes Completely
Discharged.
When you feel that the power of the tool weakens,
stop using the tool and recharge the battery.
If you continue using the tool and discharge the
battery, the battery will be damaged and its life will
be shortened.
(2) Avoid Recharging the Battery at High Temperatures.
The battery will be hot immediately after using the
tool.
If you recharge the battery too soon, the chemical
substances inside the battery will deteriorate, and
the life of the battery will be shortened.
Let the battery take rest and cool down before
recharging it.

MAINTENANCE AND INSPECTION

2. Inspecting the mounting screws
3. Maintenance of the motor
4. Cleaning of the outside
5. Storage
If there is anything you do not understand about this
product, please feel free to inquire with your nearest
authorized Service Agent.
When you perform the striking operation
continuously, the temperature protection circuit may
be activated early. (Refer to "2. Characteristics of
Electronic Pulse Driver" on page 11.)
When the activated temperature protection circuit
stops the tool, the LED light flashes to indicate that
the tool is heated to high temperature. The LED light
goes off automatically after approx. 30 seconds.
When you perform continuous operation, allow the
tool to rest for around 15 minutes at a replacement of
rechargeable battery.
When the tool is stopped by the activated temperature
protection circuit, allow the tool to cool sufficiently.
You can use the tool again when it cools down.
While the tool is not cooled sufficiently, it cannot
start up by turning the switch to on. The LED light
flashes while the switch is turned on. Please wait
until the tool cools down sufficiently.
Do not touch the nose part of the tool during
continuous operation. It is heated to high temperature.
This switch has a built-in, electronic circuit which
steplessly varies the rotation speed. Consequently, when
the switch trigger is pulled only slightly (low speed
rotation) and the motor is stopped while continuously
driving in screws, the components of the electronic
circuit parts may overheat and be damaged.
Make sure to hold the tool securely with your both hands,
and keep the tool straight to a screw or bolt. There is no
need to press the tool excessively against materials.
Be careful not to apply excessive pressing/prying
force to the tool. It may damage the tool.
Since use of a dull tool will degrade efficiency and
cause possible motor malfunction, sharpen or replace
the tool as soon as abrasion is noted.
Regularly inspect all mounting screws and ensure
that they are properly tightened. Should any of the
screws be loose, retighten them immediately. Failure
to do so may result in serious hazard.
The motor unit winding is the very "heart" of the
power tool.
Exercise due care to ensure the winding does not
become damaged and/or wet with oil or water.
When the tool is stained, wipe with a soft dry cloth or a
cloth moistened with soapy water. Do not use chloric
solvents, gasoline or paint thinner, as they melt plastics.
Store the tool in a place in which the temperature is
less than 40°C, and out of reach of children.
