Frequently Asked Questions - BTD140 MAKITA

How to change the rotation direction on the Makita BTD140 impact driver?

Use the switch located above the trigger. Push the lever to side A for clockwise rotation (tightening) and to side B for counterclockwise rotation (loosening). Place it in the neutral position when not using the tool. Never change the rotation direction before the tool has completely stopped.

Which battery to use with the Makita BTD140?

The BTD140 impact driver operates with a Makita 18 V lithium-ion battery (not included). Make sure to use a compatible battery of the same brand. Only recharge with a suitable Makita charger, between 10 °C and 40 °C. Remove the battery before any adjustment or maintenance.

How to install or remove the bit on the BTD140?

To install the bit, pull the collar in the direction of the arrow, insert the bit fully into the collar, then release the collar. To remove the bit, pull the collar again and pull the bit out firmly. Ensure the bit is securely attached; it should not come out of the collar. Use only recommended bits.

How to replace the carbon brushes of the Makita BTD140?

Disconnect the battery. Remove the rear cover by unscrewing the two screws. Lift the spring arm with a screwdriver. Remove the carbon brush caps using pliers, take out the worn brushes and insert new ones. Replace the caps ensuring they are fully seated. Always replace both carbon brushes at the same time and use identical Makita parts.

• 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.

Reversing switch action (Fig. 4)

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:

• 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.

ASSEMBLY

CAUTION:

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

Installing or removing 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. (Fig. 5)

For Models BTD130F, BTD140

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.

For Model BTD141

To install the bit, insert the bit into the sleeve as far as it will go.

To remove the bit, pull the sleeve in the direction of the arrow and pull the bit out firmly. (Fig. 6)

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.
• When it is difficult to insert the bit, pull the sleeve and insert it into the sleeve as far as it will go.
• After inserting the bit, make sure that it is firmly secured. If it comes out, do not use it.

Hook (Fig. 7)

The hook is convenient for temporarily hanging the tool. This can be installed on either side of the tool.

To install the hook, insert it into a groove in the tool housing on either side and then secure it with a screw. To remove, loosen the screw and then take it out.

OPERATION

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. (Fig. 8, 9 & 10)

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 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.

The fastening torque is affected by a wide variety of factors including the following. After fastening, always check the torque with a torque wrench.

1. 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.

1. Bolt

2. Even though the torque coefficient and the class of bolt are the same, the proper fastening torque will differ according to the diameter of bolt.

3. 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 driving position to be fastened will affect the torque.

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

MAINTENANCE

CAUTION:

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

Replacing carbon brushes

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. (Fig. 11)

Use a screwdriver to remove two screws then remove the rear cover. (Fig. 12)

Raise the arm part of the spring and then place it in the recessed part of the housing with a slotted bit screwdriver of slender shaft or the like. (Fig. 13)
