5. Operating Instructions
5.1 DDF485 Cordless Drill Driver

Image: Side view of the Makita DDF485 Cordless Drill Driver, showing the model number label and battery.
- Switch Action: To start the tool, pull the trigger. To stop, release the trigger. The tool speed increases with increased trigger pressure.
- Reversing Switch: The reversing switch changes the direction of rotation. Position it for forward (clockwise) or reverse (counter-clockwise) operation. Ensure the switch is fully engaged before operating.
- Speed Selection: The DDF485 has two mechanical speed settings. Use the speed change lever on top of the tool. Position '1' is for low speed/high torque (e.g., driving screws), and '2' is for high speed/low torque (e.g., drilling).
- Clutch Settings: The clutch ring allows you to select the desired torque setting for screw driving. The numbers correspond to increasing torque. The drill symbol bypasses the clutch for drilling applications.
- LED Work Light: The tool is equipped with an LED light that illuminates the work area when the trigger is pulled.
5.2 DTD153 Cordless Impact Driver
- Switch Action: Similar to the drill driver, pull the trigger to start and release to stop. Speed is variable based on trigger pressure.
- Reversing Switch: Use the reversing switch to change the direction of rotation for tightening or loosening fasteners.
- Impact Mechanism: The impact driver applies rotational impacts to fasteners, making it highly effective for driving long screws or bolts into dense materials.
- LED Work Light: The DTD153 also features an LED work light.
6. Maintenance
Regular maintenance ensures optimal performance and extends the life of your tools.
- Cleaning: Keep the tool's air vents clean to prevent overheating. Use a soft, damp cloth to wipe down the tool. Do not use harsh chemicals or solvents.
- Battery Care: Store batteries in a cool, dry place away from direct sunlight. Do not store fully discharged batteries for extended periods. Charge them periodically if not in use.
