OPERATING INSTRUCTIONS
Installing or removing battery cartridge (Fig. 1)
• Always switch off the tool before insertion or removal of the battery cartridge.
• To remove the battery cartridge, withdraw it from the tool while sliding the button on the side of the cartridge.
• To insert the battery cartridge, align the tongue on the battery cartridge with the groove in the housing and slip it into
place. Always insert it all the way until it locks in place with a little click. If you can see the red part on the upper side
of the button, it is not locked completely. Insert it fully until the red part cannot be seen. If not, it may accidentally fall
out of the tool, causing injury to you or someone around you.
• Do not use force when inserting the battery cartridge. If the cartridge does not slide in easily, it is not being inserted
correctly.

mance. Sound of cooling air comes out during cooling, which means no trouble on the charger.
• Yellow light will flash for warning in the following cases.
– Trouble on cooling fan
– Incomplete cool down of battery, such as, being clogged with dust
The battery can be charged in spite of the yellow warning light. But the charging time will be longer than usual in this
case. Check the sound of cooling fan, vent on the charger and battery, which can be sometime clogged with dust.
• The cooling system is in order although no sound of cooling fan comes out, if the yellow warning light is not flashing.
• Always keep the vents on charger and battery clean and clear of any obstructions for cooling.
• The products should be sent for repair or maintenance to a Makita service center, if the yellow warning light keeps
flashing.

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.
