Installing or removing battery cartridge (Fig. 1)

• Always switch off the tool before installing or removing of the battery cartridge.
• To remove the battery cartridge, slide it from the tool while sliding the button on the front of the cartridge.
• To install 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 indicator on the upper side of the button, it is not locked completely. Install it fully until the red indicator 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 installing the battery cartridge. If the cartridge does not slide in easily, it is not being inserted correctly.

Battery protection system (Lithium-ion battery with star marking) (Fig. 2)

Lithium-ion batteries with a star marking are equipped with a protection system. This system automatically cuts off power to the tool to extend battery life.

The tool will automatically stop during operation if the tool and/or battery are placed under one of the following conditions:

- Overloaded:

The tool is operated in a manner that causes it to draw an abnormally high current.

In this situation, release the trigger switch on the tool and stop the application that caused the tool to become overloaded. Then pull the trigger switch again to restart.

If the tool does not start, the battery is overheated. In this situation, let the battery cool before pulling the trigger switch again.

- Low battery voltage:

The remaining battery capacity is too low and the tool will not operate. In this situation, remove and recharge the battery.

Switch action (Fig. 3)

CAUTION:

- 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.

NOTE:

- The tool automatically stops if you keep pulling the switch trigger for about 130 seconds.

Lighting up the front lamp (Fig. 4 & 5)

CAUTION:

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

To turn on the lamp status, press the button for few seconds. To turn off the lamp status, press the button for few seconds again.

With the lamp status ON, pull the switch trigger to turn on the lamp. To turn off, release it. The lamp goes out approximately 10 seconds after releasing the switch trigger.

With the lamp status OFF, the lamp will not turn on even if the trigger is pulled.

NOTE:

- To confirm the lamp status, pull the trigger. When the lamp lights up by pulling the switch trigger, the lamp status is ON. When the lamp does not come on, the lamp status is OFF.

• While pulling the switch trigger, the lamp status cannot be changed.
• For approximately 10 seconds after releasing the switch trigger, the lamp status can be changed.

Reversing switch action (Fig. 6)

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.

Changing the impact force (Fig. 7)

Impact force grade displayed on panel	Maximum blows		Application Work
	BTD136 BTD147
Hard	3,200 (min-1)	3,400 (min-1)	Tightening when force and speed are desired.	Tightening in underwork material/Tightening long screws/Tightening bolts.
Medium	2,600 (min-1)	2,800 (min-1)	Tightening when a good finishing is needed.	Tightening in the finishing board, plaster board.
Soft	1,100 (min-1)	1,300 (min-1)	Tightening when excessive tightening need to be avoided because of potentially clogged female screw and broken or damaged screw head.	Tightening sash screw/Tightening small screws such as M6.
T mode	2,600 (min-1)	2,800 (min-1)	Tightening when speed and good finishing are needed.	Tightening self drilling screws.

012610

The impact force can be changed in four steps: hard, medium, soft, and T mode.

This allows a tightening suitable to the work.

Every time the button is pressed, the number of blows changes in four steps.

“T” is a special mode for fastening self drilling screws. In this mode, the tool starts to drive a screw with faster rotation, which is suited for drilling with the self-drilling-screw tip. Once the tool starts to tighten the screw, it impacts in medium force grade.

For approximately one minute after releasing the switch trigger, the impact force can be changed.

NOTE:

• When all lamps on the switch panel go out, the tool is turned off to save the battery power. The impact force grade can be checked by pulling the switch trigger to the extent that the tool does not operate.
• While pulling the switch trigger, the impact force grade cannot be changed.

Indicating the remaining battery capacity (Fig. 8)

When you pull the switch trigger, the LED display shows the remaining battery capacity.

The remaining battery capacity is shown as the following table.

LED indicator status Remaining battery capacity
	About 50% or more
	About 20% – 50%
	About less than 20%

012273

NOTE:

• When the LED display goes off, the tool is turned off to save the battery power. To check the remaining battery capacity, slightly pull the switch trigger.
• The LED display goes off approximately one minute after releasing the switch trigger.
• When the tool is overheated, the light flashes once per second for one minute, and then the LED display goes off. In this case, cool down the tool before operating again.
• When the LED display lights up and the tool stops even with a recharged battery cartridge, cool down the tool fully. If the status will not change, stop using and have the tool repaired by a Makita local service center.

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. 13)

Model BTD136 (Fig. 14 & 15)

Model BTD147 (Fig. 16 & 17)

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 M8 or smaller screw, choose a proper impact force and carefully adjust pressure on the switch trigger so that the screw is not damaged.
• Hold the tool pointed straight at the screw.
• If the impact force is too strong 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.

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 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.
• The manner of holding the tool or the material of driving position to be fastened will affect the torque.
• 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 except for the following troubleshooting related to the light.
• Never use gasoline, benzine, thinner, alcohol or the like. Discoloration, deformation or cracks may result.
