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 cartridge with room temperature at 10°C – 40°C (50°F – 104°F). Let a hot battery cartridge
cool down by inserting it into the charger.
4.
Charge the Nickel Metal Hydride battery cartridge when you do not use it for more than six months.
NOTE:
• The battery charger is for charging Makita-battery cartridge. Never use it for other purposes or for other manufac-
turer's batteries.
• When you charge a new battery cartridge or a battery cartridge which has not been used for a long period of time, it
may not accept a full charge. This is a normal condition and does not indicate a problem. You can recharge the bat-
tery cartridge fully after discharging it completely and recharging a couple of times.
• If you charge a battery cartridge from a just-operated tool or battery cartridge which has been left in a location
exposed to direct sunlight for a long time, the charging light may flash in red color. If this occurs, wait for a while.
Charging will begin after the battery cartridge is cooled by the cooling fan installed in the charger (DC24SA only).
When the temperature on battery is more than approx. 70°C, two charging lights may flash in red color, and when
approx. 50°C – 70°C, one charging light in red color.
• If the charging light flashes alternately in green and red color, charging is not possible. The terminals on the charger
or battery cartridge are clogged with dust or the battery cartridge is worn out or damaged.
• Any of the following conditions indicates damage to the charger and/or battery cartridge. Ask your Makita Authorized
or Factory Service Center to check them.
1) The charging light does not flash (green) when the battery charger is plugged into a power source.
2) The charging light does not light up or flash (red) when the battery is inserted in the charger port.
3) Charging is not completed at even more than two hours after red light comes ON at start of charging.
Refer to the table below for the charging time.

Selecting correct socket
Always use the correct size socket for bolts and nuts. An
incorrect size socket will result in inaccurate and incon-
sistent fastening torque and/or damage to the bolt or nut.
Installing or removing socket (Fig. 3 & 4)
CAUTION:
Always be sure that the tool is switched off and the bat-
tery cartridge is removed before installing or removing
the socket.
1.
For socket without O-ring and pin
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.
2.
For socket with O-ring and pin
Move the O-ring out of the groove in the socket and
remove the pin from the socket. Fit the socket onto
the anvil of the tool so that the hole in the socket is
aligned with the hole in the anvil. Insert the pin
through the hole in the socket and anvil. Then return
the O-ring to the original position in the socket
groove to retain the pin. To remove the socket, follow
the installation procedures in reverse.

Switch action (Fig. 5)
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 trigger. Tool speed is
increased by increasing pressure on the trigger. Release
the trigger to stop.
Reversing switch action (Fig. 6)
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.
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 counter-
clockwise rotation. When the switch lever is in the neutral
position, the switch trigger cannot be pulled.
