Setup
1. Charging the Battery
The Makita DDF 482 RTJ comes with two 18V 5.0 Ah Lithium-ion batteries and a compatible charger (DC18RC). Ensure batteries are fully charged before first use.

Figure 2: Makita DC18RC Charger and 18V 5.0 Ah Batteries. This image displays the battery charger unit along with two 18V 5.0 Ah Lithium-ion battery packs, essential for powering the drill driver.
- Connect the charger to a standard power outlet.
- Insert the battery pack into the charger. The charging indicator light will show the charging status.
- Once charging is complete, remove the battery from the charger.
Note: Do not charge damaged batteries. Refer to the charger manual for detailed charging instructions and safety warnings.
2. Installing/Removing the Battery
- To Install: Align the battery pack with the grooves in the tool's handle and slide it in until it clicks into place.
- To Remove: Press the release button on the battery pack and slide it out of the tool.
3. Installing/Removing a Drill Bit or Driver Bit
- Rotate the chuck counter-clockwise to open the jaws.
- Insert the bit fully into the chuck.
- Rotate the chuck clockwise to tighten the jaws securely around the bit. Ensure the bit is centered and firmly held.
- To remove, rotate the chuck counter-clockwise to loosen the jaws and pull the bit out.
Operating Instructions
1. Selecting Speed
The drill driver has a 2-speed mechanical gearbox:
- Speed 1 (Low Speed): 0-600 RPM. Ideal for heavy-duty drilling (larger holes), driving large screws, or applications requiring high torque.
- Speed 2 (High Speed): 0-1900 RPM. Suitable for light-duty drilling (smaller holes) and faster driving of smaller screws.
Use the speed selector switch located on top of the tool to choose the desired speed. Ensure the tool is stopped before changing speeds.
2. Adjusting Torque
The torque adjustment ring allows you to set the clutch to one of 21 settings, or to drill mode. This prevents over-tightening of screws and damage to the workpiece or screw head.
- Rotate the ring to align the desired torque number with the arrow on the tool body. Lower numbers are for smaller screws or softer materials; higher numbers are for larger screws or harder materials.
- For drilling, set the ring to the drill symbol (no clutch action).
3. Starting and Stopping
- To Start: Pull the trigger switch. The speed increases with increased pressure on the trigger.
- To Stop: Release the trigger switch.
4. Reversing Rotation
The forward/reverse lever, located above the trigger, controls the direction of rotation.
- Push the lever to the left for forward rotation (drilling and driving screws).
- Push the lever to the right for reverse rotation (removing screws).
- Center the lever for trigger lock (prevents accidental starting).
Caution: Always ensure the tool has come to a complete stop before changing the direction of rotation.
5. LED Job Light
The LED job light automatically illuminates when the trigger is pulled, providing visibility in dimly lit areas. It has a pre-glow and after-glow function.
Maintenance
Regular maintenance ensures optimal performance and extends the life of your tool.
Cleaning
- Keep the tool's ventilation openings clean to prevent overheating.
- Wipe the tool body with a soft, damp cloth. Do not use strong detergents or solvents.
- Regularly clean the chuck jaws to ensure proper grip on bits.
Storage
When not in use, store the drill driver, batteries, and charger in the provided Makpac 2 case in a cool, dry place, out of reach of children.

- For long-term storage, charge batteries to about 50% capacity.
Troubleshooting
This section addresses common issues you might encounter with your drill driver.
| Problem | Possible Cause | Solution |
|---|---|---|
| Tool does not start. | Battery not inserted correctly. Battery discharged. Forward/reverse lever in neutral (locked) position. | Re-insert battery firmly. Charge battery. Move lever to forward or reverse position. |
| Reduced power or speed. | Battery low. Overload protection activated. | Charge battery. Reduce pressure on the tool or use a lower speed/higher torque setting. |
| Bit slips in chuck. | Chuck not tightened sufficiently. Bit shank is dirty or damaged. | Tighten chuck firmly. Clean or replace bit. |
| Tool stops during operation. | Overload protection activated (e.g., due to excessive load or high temperature). | Release the trigger, allow the tool to cool down, and reduce the load. |
