Battery Protection System; Operation - Makita TW100D Instruction Manual

To remove the battery cartridge, withdraw it from the tool while
pressing the buttons on both sides of the cartridge.
To install the battery cartridge, hold it so that the battery
cartridge front shape fits to that of the battery install-
ment opening and slip it into place. Insert it all the way
until it locks in place with a little click.
CAUTION:
• Always insert the battery cartridge all the way
until it locks in place. If not, it may accidentally
fall out of the tool, causing injury to you or some-
one around you.
• Do not install the battery cartridge forcibly. If the
cartridge does not slide in easily, it is not being
inserted correctly.

Battery protection system

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 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.
• Low battery voltage:
The remaining battery capacity is too low
and the tool will not operate. If you pull the
switch trigger, the motor runs again but stops
soon. In this situation, remove and recharge
the battery.
Switch action
► Fig.2: 1. Switch trigger
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.
Turning on the front lamp
► Fig.3: 1. Lamp
CAUTION:
• Do not look in the light or see the source of light
directly.
Pull the switch trigger to turn on the light. The lamp
keeps on lighting while the switch trigger is being pulled.
NOTE:
• Use a dry cloth to wipe the dirt off the lens of
lamp. Be careful not to scratch the lens of lamp,
or it may lower the illumination.
Reversing switch action
► Fig.4: 1. Reversing switch lever
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.
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.
• When not operating the tool, always set the
reversing switch lever to the neutral position.
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.
Selecting correct socket
Always use the correct size socket for bolts and nuts. An
incorrect size socket will result in inaccurate and inconsistent
fastening torque and/or damage to the bolt or nut.
Installing or removing socket
► Fig.5: 1. Socket 2. Anvil
To install the socket, push it onto the anvil of the tool
until it locks into place.
To remove the socket, simply pull it off.

OPERATION

► Fig.6
The proper fastening torque may differ depending upon
the kind or size of the bolt, the material of the workpiece
to be fastened, etc. The relation between fastening
torque and fastening time is shown in the figures.
