Functional Description - Makita BTD044 Manuel D'instructions

5. Do not short the battery cartridge:
(1) Do not touch the terminals with any
conductive material.
(2) Avoid storing battery cartridge in a container
with other metal objects such as nails, coins,
etc.
(3) Do not expose battery cartridge to water or
rain.
A battery short can cause a large current flow,
overheating, possible burns and even a break-
down.
6. Do not store the tool and battery cartridge in
locations where the temperature may reach or
exceed 50°C (122°F).
7. Do not incinerate the battery cartridge even if it
is severely damaged or is completely worn out.
The battery cartridge can explode in a fire.
8. Be careful not to drop or strike battery.
9. Do not use a damaged battery.
SAVE THESE INSTRUCTIONS.
Tips for maintaining maximum battery life
1. Charge the battery cartridge before completely
discharged.
Always stop tool operation and charge the
battery cartridge when you notice less tool
power.
2. Never recharge a fully charged battery cartridge.
Overcharging shortens the battery service life.
3. Charge the battery
temperature at 10°C – 40°C (50°F – 104°F). Let a
hot battery cartridge cool down before charging
it.
4. Charge the battery cartridge once in every six
months if you do not use it for a long period of
time.

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 (Fig. 1)
CAUTION:
• Always switch off the tool before installing or removing
of the battery cartridge.
• Hold the tool and the battery cartridge 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.
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.

• 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 (Fig. 2)
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.
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 the orange lamp lights up (or flickers) on BL1430A
or flickers on BL1415NA, the tool stops because of little
remaining battery capacity (Auto-stop mechanism).
Charge the battery cartridge at this time 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 battery
capacity at this time. For BL1430A only, use Makita
refreshing adapter to refresh the battery.
Auto-stop mechanism (Fig. 3)
The tool stops automatically after the battery capacity
reaches under 20% on BL1430A or 15% on BL1415NA
to prevent the lack of fastening torque. Charge the
battery or use a new fully charged one.
Battery protection system (BL1415NA)
The tool is equipped with a battery protection system.
This system automatically cuts off power to the motor to
extend battery life.
The tool will automatically stop during operation if the
tool and/or battery are placed under the following
conditions:
• Overloaded:
The tool is operated in a manner that causes it to
draw an abnormally high current.
In this situation, release the switch trigger on the tool
and stop the application that caused the tool to
become overloaded. Then pull the switch trigger
again to restart.
If the tool does not start, the battery is overheated. In
this situation, let the battery cool before pulling the
switch trigger again.
NOTE:
• The overheat protection works only with BL1415NA.
Switch action (Fig. 4)
CAUTION:
• Before inserting the battery cartridge 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. Tool speed
is increased by increasing pressure on the switch trigger.
Release the switch trigger to stop.
Reversing switch action (Fig. 5)
CAUTION:
• Always check the direction of rotation before operation.
• Use the reversing switch only after the tool comes to a
complete stop. Changing the direction of rotation
before the tool stops may damage the tool.
