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.

1. 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.

2. 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.

3. 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.

4. 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.

5. Do not overreach. Keep proper footing and balance at all times. Proper footing and balance enable better control of the tool in unexpected situations.

6. Use safety equipment. Always wear eye protection. Dust mask, non-skid safety shoes, hard hat, or hearing protection must be used for appropriate conditions.

DO NOT let comfort or familiarity with product (gained from repeated use) replace strict adherence to cordless impact driver safety rules. If you use this tool unsafely or incorrectly, you can suffer serious personal injury.

1. Hold tool by insulated gripping surfaces when performing an operation where the cutting tool may contact hidden wiring. Contact with a “live” wire will also make exposed metal parts of the tool “live” and shock the operator.

2. Be aware that this tool is always in an operating condition, because it does not have to be plugged into an electrical outlet.

3. Always be sure you have a firm footing. Be sure no one is below when using the tool in high locations.

4. Hold the tool firmly.

5. Wear ear protectors.

1. Use clamps or other practical way 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.

2. Do not force 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.

3. Do not use tool if switch does not turn it on or off. A tool that cannot be controlled with the switch is dangerous and must be repaired.

4. Disconnect battery pack from 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.

5. Store idle tools out of reach of children and other untrained persons. Tools are dangerous in the hands of untrained users.

6. When battery pack is not in use, keep it away from other metal objects like: paper clips, coins, keys, nails, screws, or other small metal objects that can make a connection from one terminal to another. Shorting the battery terminals together may cause sparks, burns, or a fire.

7. Maintain tools with care. Keep cutting tools sharp and clean. Properly maintained tools with sharp cutting edge are less likely to bind and are easier to control.

8. Check for misalignment or binding of moving parts, breakage of parts, and any other condition that may affect the tool’s operation. If damaged, have the tool serviced before using. Many accidents are caused by poorly maintained tools.

9. Use only accessories that are recommended by the manufacturer for your model. Accessories that may be suitable for one tool may create a risk of injury when used on another tool.

1. Before using the battery cartridge, read all instructions and cautionary markings on (1) battery charger, (2) battery, and (3) product using the battery.

2. Do not disassemble the battery cartridge.

3. If operating time has become excessively shorter, stop operating immediately. It may result in a risk of overheating, possible burns and even an explosion.

4. If electrolyte gets into your eyes, rinse them out with clear water and seek medical attention right away. It may result in loss of your eyesight.

5. Always cover the battery terminals with the battery cover when the battery cartridge is not used.

6. Do not short the battery cartridge:

(1) Do not touch the terminals with any conductive material.

(2) Avoid storing the battery cartridge in a container with other metal objects such as nails, coins, etc.

(3) Do not expose the battery cartridge to water or rain. A battery short can cause a large current flow, overheating, possible burns and even a breakdown.

7. Do not store the tool and battery cartridge in locations where the temperature may reach or exceed 50°C (122°F).

8. Do not incinerate the battery cartridge even if it is severely damaged or is completely worn out. The battery cartridge can explode in a fire.

9. Be careful not to drop or strike the battery.

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 at room temperature, from 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.

Always switch off the tool before insertion or removal of the battery cartridge.

To remove the battery cartridge: Withdraw it from the tool while pressing the buttons on both sides 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 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.

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. The tool’s speed is increased by increasing pressure on the switch trigger. Release the switch trigger to stop.

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

The MAKITA 6916D 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.

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.

CAUTION: Always be sure that the tool is switched off and the battery cartridge is removed before carrying out any work on the tool.

Use only the driver bit or socket bit shown in the figure in the manual. Do not use any other driver bit or socket bit.

To install the bit:

1. Pull the sleeve in the direction of the arrow shown in the manual.

2. Insert the bit into the sleeve as far as it will go.

3. 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.

NOTE: 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 above.

The proper fastening torque may differ depending upon the kind or size of the screw/bolt and the material of the workpiece. The relation between fastening torque and fastening time is shown in the figures in the instruction manual.

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.

NOTE:

• Use the proper bit for the head of the screw/bolt that you wish to use.

• When fastening a 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. The factors include:

1. Battery cartridge condition: When the battery cartridge is discharged almost completely, voltage will drop and the fastening torque will be reduced.

2. Driver bit or socket bit: Failure to use the correct size driver bit or socket bit will cause a reduction in the fastening torque.

3. Bolt:

• 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. Manner of holding: The manner of holding the tool or the material of the driving position to be fastened will affect the torque.

5. Operating speed: Operating the tool at low speed will cause a reduction in the fastening torque.

CAUTION: Always be sure that the tool is switched off and the battery cartridge is removed before attempting to perform inspection or maintenance.

1. Remove and check the carbon brushes regularly. Replace when they wear down to the limit mark.

2. 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.

3. Use a screwdriver to remove the brush holder caps.

4. Take out the worn carbon brushes, insert the new ones and secure the brush holder caps.

5. After replacing brushes, insert the battery cartridge into the tool and break in brushes by running the tool with no load for about 1 minute.

6. Then check the tool while running and electric brake operation when releasing the switch trigger. If the electric brake is not working well, ask your local Makita service center for repair.
