Conditioning charge
Conditioning charge can extend the life of battery by automatically searching the optimum charging condition
for the batteries in every situation.
The battery treated in the following conditions repeatedly, will wear out quicker, and yellow warning light may
flash.
1. Recharge of battery with its high temperature
2. Recharge of battery with its low temperature
3. Recharge of full charged battery
4. Over-discharge of battery (contunue to discharge battery in spite of down of power.)
5. 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
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 before charging it.
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
manufacturer’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 battery 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. 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.
Side grip (auxiliary handle) (Fig. 3)
Always use the side grip to ensure operating safety.
Install the side grip so that the teeth on the grip fit in
between the protrusions on the tool barrel. Then
tighten the grip by turning clockwise at the desired
position. It may be swung 360° so as to be secured at
any position.
Adjustable depth rod (Fig. 4)
The adjustable depth rod is used to drill holes of
uniform depth. Loosen the thumb screw, set to
desired position, then tighten the thumb screw.
Installing or removing driver bit or drill bit
(Fig. 5 & 6)
Important:
Always be sure that the tool is switched off and the
battery cartridge is removed before installing or
removing the bit.
Turn the sleeve counterclockwise to open the chuck
jaws. Place the bit in the chuck as far as it will go. Turn
the sleeve clockwise to tighten the chuck. To remove
the bit, turn the sleeve counterclockwise.
When not using the driver bit, keep it in the bit holders.
Bits up to 45 mm long can be kept there.
