Conditioning charge (DC24SA only)

Conditioning charge can extend the life of battery by automatically searching the optimum charging condition for the
batteries in every situation.

The battery employed in the following conditions repeatedly, will be worn out shortly, and yellow warning light may
flash.
1.

Recharge of battery with its high temperature

Recharge of battery with its low temperature

Recharge of full charged battery

Over-discharge of battery (contunue to discharge battery in spite of down of power.)

Recharge under broken cooling system

The charging time of such battery is longer than usual.

Trickle charge (Maintenance charge)

If you leave the battery cartridge in the charger to prevent spontaneous discharging after full charge, the charger will
switch into its “trickle charge (maintenance charge)” mode and keep the battery cartridge fresh and fully charged.

Tips for maintaining maximum battery life

Charge the battery cartridge before completely discharged.
Always stop tool operation and charge the battery cartridge when you notice less tool power.

Never recharge a fully charged battery cartridge.
Overcharging shortens the battery service life.

Charge the battery cartridge with room temperature at 10°C – 40°C (50°F – 104°F).
Let a hot battery cartridge cool down before charging it.

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.

Switch action (Fig. 3)

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. 4)

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.

Selecting action mode

Rotation with hammering (Fig. 5)

For drilling in concrete, masonry, etc., depress the lock
button and rotate the change lever so that the pointer
points to the

symbol. Use a tungsten- carbide tipped

bit.

Rotation only (Fig. 6)

For drilling in wood, metal or plastic materials, depress
the lock button and rotate the change lever so that the
pointer points to the

symbol. Use a twist drill bit or

wood bit.

Hammering only (Fig. 7)

For chipping, scaling or demolition operations, depress
the lock button and rotate the change lever so that the
pointer points to the

symbol. Use a bull point, cold

chisel, scaling chisel, etc.

CAUTION:
• Do not rotate the change lever when the tool is running.

The tool will be damaged.

• To avoid rapid wear on the mode change mechanism,

be sure that the change lever is always positively
located in one of the three action mode positions.
