How do I charge the battery cartridge?

1. Plug the battery charger into the proper AC voltage source. The charging light will flash in green color.
2. Insert the battery cartridge so that the plus and minus terminals on the battery cartridge are on the same sides as their respective markings on the charger. Insert the cartridge fully into the ports so that it rests on the charger port floor.
3. When the battery cartridge is inserted, the charging light color will change from green to red and charging will begin. The charging light will remain lit steadily during charging.
4. When the charging light color changes from red to green, the charging cycle is complete.
5. If you leave the battery cartridge in the charger after the charging cycle is complete, the charger will switch into its “trickle charge (maintenance charge)” mode which will last approximately 24 hours.
6. After charging, unplug the charger from the power source.

What are some notes about charging the battery cartridge?

The battery charger is for charging Makita battery cartridges only. 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 a battery cartridge which has been left in a location exposed to direct sunlight or heat 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 cools. The battery cartridge will cool faster if you remove the battery cartridge from the battery charger. If the charging light flashes alternately in green and red color, charging is not possible. The terminals on the charger or battery cartridge may be clogged with dust, or the battery cartridge may be worn out or damaged.

What is trickle charge (maintenance charge)?

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

---

What are some tips for maintaining maximum battery life?

1. Charge the battery cartridge before it is 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.

How does the switch action work?

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.

---

What is the electric brake feature?

This tool is equipped with an electric brake. If the tool consistently fails to quickly stop after switch trigger release, have the tool serviced at a Makita service center.

---

How do I light up the front lamp?

Pull the switch trigger to light up the lamp. The lamp keeps on lighting while the switch trigger is being pulled. Use a dry cloth to wipe the dirt off the lens of the lamp. Be careful not to scratch the lens of the lamp, or it may lower the illumination. Do not look in the light or see the source of light directly.

---

How does the reversing switch action work?

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 counterclockwise rotation. When the reversing switch lever is in the neutral position, the switch trigger cannot be pulled. 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.

How do I install or remove the driver bit or socket bit?

Use only the driver bit or socket bit shown in the figure. Do not use any other driver bit or socket bit. To install the bit, pull the sleeve in the direction of the arrow and insert the bit into the sleeve as far as it will go. Then release the sleeve to secure the bit. To remove the bit, pull the sleeve in the direction of the arrow and pull the bit out firmly. If the bit is not inserted deep enough into the sleeve, the sleeve will not return to its original position and the bit will not be secured. In this case, try re-inserting the bit according to the instructions.

---

How do I operate the tool?

The proper fastening torque may differ depending upon the kind or size of the screw/bolt, the material of the workpiece to be fastened, etc. The relation between fastening torque and fastening time is shown in the figures. Hold the tool firmly and place the point of the driver bit in the screw head. Apply forward pressure to the tool to the extent that the bit will not slip off the screw and turn the tool on to start operation. Use the proper bit for the head of the screw/bolt that you wish to use. When fastening screw M8 or smaller, carefully adjust pressure on the switch trigger so that the screw is not damaged. Hold the tool pointed straight at the screw. If you tighten the screw for a time longer than shown in the figures, the screw or the point of the driver bit may be overstressed, stripped, damaged, etc. Before starting your job, always perform a test operation to determine the proper fastening time for your screw. If the tool is operated continuously until the battery cartridge has discharged, allow the tool to rest for 15 minutes before proceeding with a fresh battery. The fastening torque is affected by a wide variety of factors. After fastening, always check the torque with a torque wrench.

---

What factors affect fastening torque?

1. When the battery cartridge is discharged almost completely, voltage will drop and the fastening torque will be reduced.
2. Failure to use the correct size driver bit or socket bit will cause a reduction in the fastening torque.
3. Even though the torque coefficient and the class of bolt are the same, the proper fastening torque will differ according to the diameter of the bolt. Even though the diameters of bolts are the same, the proper fastening torque will differ according to the torque coefficient, the class of bolt, and the bolt length.
4. The manner of holding the tool or the material of the driving position to be fastened will affect the torque.
5. Operating the tool at low speed will cause a reduction in the fastening torque.

How do I replace carbon brushes?

Remove and check the carbon brushes regularly. Replace them when they wear down to the limit mark. Keep the carbon brushes clean and free to slip in the holders. Both carbon brushes should be replaced at the same time. Use only identical carbon brushes. Use a screwdriver to remove the brush holder caps. Take out the worn carbon brushes, insert the new ones, and secure the brush holder caps. After replacing the brushes, insert the battery cartridge into the tool and break in the brushes by running the tool with no load for about 1 minute. Then check the tool while running and the electric brake operation when releasing the switch trigger. If the electric brake is not working well, ask your local Makita service center for repair.

1. Keep your work area clean and well lit. Cluttered benches and dark areas invite accidents.
2. Do not operate power tools in explosive atmospheres, such as in the presence of flammable liquids, gases, or dust. Power tools create sparks which may ignite the dust or fumes.
3. Keep bystanders, children, and visitors away while operating a power tool. Distractions can cause you to lose control.

Electrical Safety 4. A battery operated tool with integral batteries or a separate battery pack must be recharged only with the specified charger for the battery. A charger that may be suitable for one type of battery may create a risk of fire when used with another battery. 5. Use battery operated tool only with specifically designated battery pack. Use of any other batteries may create a risk of fire.

Personal Safety 6. Stay alert, watch what you are doing, and use common sense when operating a power tool. Do not use the tool while tired or under the influence of drugs, alcohol, or medication. A moment of inattention while operating power tools may result in serious personal injury. 7. Dress properly. Do not wear loose clothing or jewelry. Contain long hair. Keep your hair, clothing, and gloves away from moving parts. Loose clothes, jewelry, or long hair can be caught in moving parts. 8. Avoid accidental starting. Be sure the switch is in the locked or off position before inserting the battery pack. Carrying tools with your finger on the switch or inserting the battery pack into a tool with the switch on invites accidents. 9. Remove adjusting keys or wrenches before turning the tool on. A wrench or a key that is left attached to a rotating part of the tool may result in personal injury. 10. Do not overreach. Keep proper footing and balance at all times. Proper footing and balance enable better control of the tool in unexpected situations. 11. Use safety equipment. Always wear eye protection. Dust mask, non-skid safety shoes, hard hat, or hearing protection must be used for appropriate conditions.

Tool Use and Care 12. Use clamps or other practical ways to secure and support the workpiece to a stable platform. Holding the work by hand or against your body is unstable and may lead to loss of control. 13. Do not force the tool. Use the correct tool for your application. The correct tool will do the job better and safer at the rate for which it is designed. 14. Do not use the tool if the switch does not turn it on or off. A tool that cannot be controlled with the switch is dangerous and must be repaired. 15. Disconnect the battery pack from the tool or place the switch in the locked or off position before making any adjustments, changing accessories, or storing the tool. Such preventive safety measures reduce the risk of starting the tool accidentally. 16. Store idle tools out of reach of children and other untrained persons. Tools are dangerous in the hands of untrained users. 17.
