Battery Protection System; Fig.3 - Makita DTD152 Instruction Manual

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.

Battery protection system

Lithium-ion battery with star marking
►Fig.2: 1. Star marking
Lithium-ion batteries with a star marking are equipped
with a protection system. This system automatically
cuts off power to the tool to extend battery life.
The tool will automatically stop during operation if the
tool and/or battery are placed under one of 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.
Low battery voltage:
The remaining battery capacity is too low and the tool
will not operate. In this situation, remove and recharge
the battery.
Indicating the remaining battery
capacity
Only for battery cartridges with "B" at the end of the
model number
►Fig.3: 1. Indicator lamps
Press the check button on the battery cartridge to indi-
cate the remaining battery capacity. The indicator lamps
light up for few seconds.

Switch action
►Fig.4: 1. Switch trigger
CAUTION: Before inserting 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. Tool
speed is increased by increasing pressure on the switch
trigger. Release the switch trigger to stop.
Lighting up the front lamp
►Fig.5: 1. Lamp
CAUTION: Do not look in the light or see the
source of light directly.
Pull the switch trigger to light up the lamp. The lamp
keeps on lighting while the switch trigger is being pulled.
The lamp goes out 10 -15 seconds after releasing the
trigger.
NOTE: Use a dry cloth to wipe the dirt off the lens of
the lamp. Be careful not to scratch the lens of lamp, or
it may lower the illumination.
Reversing switch action
►Fig.6: 1. Reversing switch lever
CAUTION: Always check the direction of rota-
tion before operation.
CAUTION: Use the reversing switch only after
the tool comes to a complete stop. Changing the
direction of rotation before the tool stops may dam-
age the tool.
CAUTION: When not operating the tool, always
set the reversing switch lever to the neutral
position.
This tool has a reversing switch to change the direction
of rotation. Depress the reversing switch lever from the
A side for clockwise rotation or from the B side for coun-
terclockwise rotation.
When the reversing switch lever is in the neutral posi-
tion, the switch trigger cannot be pulled.
ASSEMBLY
CAUTION: Always be sure that the tool is
switched off and the battery cartridge is removed
before carrying out any work on the tool.
