Note:

• Manufacturer reserves the right to change specifications without notice.

• Specifications may differ from country to country.

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. 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.

2. Use battery operated tool only with specifically designated battery pack. Use of any other batteries may create a risk of fire.

1. Stay alert, watch what you are doing, and use common sense when operating a power tool. Do not use 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 switch is in the locked or off position before inserting 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.

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.

DO NOT let comfort or familiarity with product (gained from repeated use) replace strict adherence to cordless Angle Nut Runner 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. Keep hands away from rotating parts.

V ……………….. volts

⎓ ……………….. direct current

n₀ ……………….. no load speed

…/min. ………… revolutions or reciprocation per minute

The following show the symbols used for the charger. Be sure that you understand their meaning before use.

• Steady green light: Ready to charge

• Flashing green light: Charging

• Green light with 100%: Charging complete

• Alternating green and orange lights: Delay charge (Cooling)

• Flashing orange light: Defective battery

• Yellow light: Conditioning

• Flashing red light: Cooling abnormality

Always be sure that the tool is switched off and the battery cartridge is removed before adjusting or checking function on the tool. Always switch off the tool before insertion or removal of the battery cartridge.

For Models BFL081F, BFL121F, BFL200F:

• To remove the battery cartridge, withdraw it from the tool while sliding the button on the front 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.

For Models BFL080F, BFL120F:

• 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.

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.

5. Always stop tool operation and charge the battery cartridge when you notice that the warning lamp lightened up.

A refreshing battery adapter (optional accessory) can refresh an inactive battery cartridge.

• Refresh charging should be done once a week.

• When you charge a new battery cartridge or a battery cartridge that has not been used for a long time, it may not accept a full charge. In this case, refresh charging must be done. The battery cartridge may decrease the tool performance, because the chemical substance of the battery cartridge is inactive.

When charging:

When the charging begins, the first (far left) indicating lamp begins to flicker. Then, as charging proceeds, the other lamps light, one after the other, to indicate the battery capacity.

When using:

When the tool is switched on, the lamps will light to indicate the remaining battery capacity. When the tool is switched off, the light goes out. If the battery has not been used for a long time, or is needed refresh charging, the orange lamp begins to flicker. Use Makita refreshing adapter to refresh the battery.

CAUTION: A battery cartridge extracted from the charger that has been unplugged with the battery cartridge inserted does not indicate the battery capacity due to its protective function even if the tool is switched on after the battery insertion into the tool. At this time, recharge it for about five seconds before use.

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. Release the switch trigger to stop.

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 counterclockwise rotation.

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

CAUTION: Do not look in the light or see the source of light directly.

Pull the switch trigger to light up the lamp. The lamp keeps on lighting while the switch trigger is being pulled. The light automatically goes out 10 seconds after the switch trigger is released.

NOTE: Use a dry cloth to wipe the dirt off the lens of lamp. Be careful not to scratch the lens of lamp, or it may lower the illumination.

When you wish to drive machine screws, wood screws, hex bolts, etc. with the predetermined torque, adjust the fastening torque as follows.

1. First remove the battery cartridge from the tool.

2. Loosen the screws securing the light cover.

3. Rotate the ring in the front of the tool by hand so that a hole can be seen below the ring.

4. Place the battery cartridge in place and pull the switch trigger. Release it so that the adjusting ring rotates and becomes visible in the hole. And then remove the battery cartridge.

5. Use an optional adjusting grip to adjust the fastening torque. Insert the pin of the adjusting grip into the hole in the front of the tool. And then, turn the adjusting grip clockwise to set a greater fastening torque, and counter-clockwise to set a smaller fastening torque.

6. Align the yellow line with your desired number on the fastening torque scale.

7. Insert the battery cartridge and be sure that a fastening torque has been set up by using a fastening torque tester.

8. Tighten the screws to secure the light cover and then rotate the ring in front of the tool until the ring is locked.

NOTE: Numbers on the fastening torque scale is a guideline to set up your desired fastening torque.

Always use the correct size socket for bolts and nuts. An incorrect size socket will result in inaccurate and inconsistent fastening torque and/or damage to the bolt or nut.

To install the socket, push it onto the square drive of the tool with one hand by depressing a pin on the square drive with another hand until it locks into place. To remove the socket, simply pull it off depressing the pin on the square drive.

Hold the tool firmly and place the socket over the bolt or nut. Then switch the tool on. When the clutch cuts in, the motor will stop automatically. Then release the switch trigger.

NOTE: Hold the tool with its square drive pointed straight at the bolt or nut, or the bolt or nut will be damaged.

Use the tool within the limits of fastening capacity. If you use the tool beyond the limits, the clutch does not work. And the tool cannot deliver enough fastening torque. The range of fastening capacity for the BFL121F is between approximately 5 N.m and 12 N.m.

NOTE:

• The revolution angle means the angle which a screw/bolt revolves when the tool attains to 100% from 50% of desired torque.

• Use of a low temperature conditioned battery cartridge may sometimes give warning for battery cartridge capacity by warning lamp and beeper which makes the tool stop immediately. In this case, the range of fastening capacity may be inferior to those shown in the above even if a charged battery cartridge is used.

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

Remove and check the carbon brushes regularly. Replace 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.
