MAKITA DTD154 (01) PDF Document

Due to a continuing program of research and development, the specifications are subject to change without notice. Specifications and battery cartridge may differ from country to country. Weight is calculated with the battery cartridge, according to EPTA-Procedure 01/2003.

1. Hold the MAKITA DTD154 by its insulated gripping surfaces, when performing an operation where the fastener may contact hidden wiring. Fasteners contacting a “live” wire may make exposed metal parts of the power tool “live” and could give the operator an electric shock.

2. Always be sure you have a firm footing.

3. Be sure no one is below when using the tool in high locations.

4. Hold the tool firmly.

5. Wear ear protectors.

6. Do not touch the bit or the workpiece immediately after operation. They may be extremely hot and could burn your skin.

7. Keep hands away from rotating parts.

WARNING: DO NOT let comfort or familiarity with the product (gained from repeated use) replace strict adherence to safety rules for the subject product. MISUSE or failure to follow the safety rules may cause serious personal injury.

Always switch off the MAKITA DTD154 before installing or removing the battery cartridge. Hold the tool and the battery cartridge firmly during this process to prevent them from slipping and causing injury.

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. 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.

CAUTION: Always install the battery cartridge fully until the red indicator cannot be seen. If not, it may accidentally fall out of the tool. Do not install the battery cartridge forcibly. If the cartridge does not slide in easily, it is not being inserted correctly.

1. Charge the battery cartridge before it is completely discharged. Always stop tool operation and charge the battery 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 battery cartridge if you do not use it for a long period (more than six months).

This function is available only for battery cartridges with “B” at the end of the model number.

Press the check button on the battery cartridge to indicate the remaining battery capacity. The indicator lamps will light up for a few seconds.

NOTE: Depending on the conditions of use and the ambient temperature, the indication may differ slightly from the actual capacity.

The MAKITA DTD154 is equipped with a tool/battery protection system that automatically cuts off power to the motor to extend tool and battery life. The tool will automatically stop during operation if the tool or battery is placed under one of the following conditions:

Overload protection: When the battery is operated in a manner that causes it to draw an abnormally high current, the tool automatically stops without any indication. To resolve this, turn the tool off, stop the application that caused the overload, and then turn the tool on to restart.

Overheat protection: When the tool/battery is overheated, the tool stops automatically. In this situation, let the battery cool before turning the tool on again.

Overdischarge protection: When the battery capacity is not enough, the tool stops automatically. In this case, remove the battery from the tool and charge the battery.

NOTE: Overload protection will work only with batteries that have a star marking.

Before installing the battery cartridge into the MAKITA DTD154, always check 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 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.

NOTE: The tool automatically stops if you keep pulling the switch trigger for about 6 minutes.

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

Pull the switch trigger to turn on the lamp. The lamp goes out approximately 10 seconds after releasing the switch trigger.

To keep the lamp off, you can turn off the lamp status. First, pull and release the switch trigger. Then, press the lamp button for one second within 10 seconds. To turn the lamp status on again, press the button again similarly.

NOTE:

To confirm the lamp status, pull the trigger. When the lamp lights up, the lamp status is ON. When it does not come on, the status is OFF.

When the tool is overheated, the light flashes for one minute, and then the LED display goes off. In this case, cool down the tool before operating again.

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

The MAKITA DTD154 has a reversing switch to change the direction of rotation. Always check the direction of rotation before operation.

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: 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.

You can change the impact force of the MAKITA DTD154 in four steps: hard, medium, soft, and T mode. This allows for tightening suitable to the work. Every time the button is pressed, the number of blows changes in four steps.

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

T mode explained: “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.

NOTE: When all lamps on the switch panel go out, the tool is turned off to save 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.

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/socket bit with a 9 mm (3/8″) insertion portion as shown in the manual. Do not use any other driver bit/socket bit.

To install the driver bit:

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

To remove the driver bit:

Pull the sleeve in the direction of the arrow and pull the driver bit out.

NOTE: If the driver bit is not inserted deep enough into the sleeve, the sleeve will not return to its original position and the driver bit will not be secured. In this case, try re-inserting the bit. When it is difficult to insert the driver bit, pull the sleeve and insert it into the sleeve as far as it will go. After inserting the driver bit, make sure that it is firmly secured. If it comes out, do not use it.

The hook is convenient for temporarily hanging the MAKITA DTD154. It 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 the hook: Loosen the screw and then take it out.

The fastening torque is affected by a wide variety of factors. After fastening, always check the torque with a torque wrench. Factors include:

1. Battery Charge: When the battery cartridge is almost completely discharged, 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 if the torque coefficient and class of bolt are the same, the proper fastening torque will differ according to the diameter of the bolt.

– Even if 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. Holding Manner: 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.

If the impact force is too strong or you tighten the screw for too long, the screw or bit may be overstressed, stripped, or damaged. Before starting your job, always perform a test operation to determine the proper fastening time for your screw.

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

NOTICE: Never use gasoline, benzine, thinner, alcohol or the like. Discoloration, deformation or cracks may result.

To maintain product SAFETY and RELIABILITY, repairs, any other maintenance or adjustment should be performed by Makita Authorized or Factory Service Centers, always using Makita replacement parts.

If you use a spare battery to continue the operation, rest the tool at least 15 min.
