Frequently Asked Questions - ROS 625DB Mirka
What is the sanding stroke of the Mirka ROS 625DB?
The sanding stroke is 5 mm, allowing efficient sanding while maintaining good precision and a correct finish.
How do I change the sanding pad?
Unplug the tool. Remove the used abrasive, then loosen the central pad bolt using a suitable socket wrench. Install the new pad, ensuring that the indicated rotation direction is respected, then firmly tighten the bolt.
What type of abrasive should I use?
Use self-adhesive (Velcro) abrasives with a diameter of 150 mm. Mirka Abranet, Netto, or traditional discs are compatible with this pad.
Sanding generates dust: how does the extraction system work?
The sander is equipped with an integrated dust bag attached to the rear. The pad holes draw dust into the bag through the airflow generated by the motor. Regularly check that the bag is not clogged.
How do I clean and maintain the tool?
After each use, unplug the tool and empty the bag. Clean the housing and ventilation slots with a dry cloth. Check the pad and carbon brushes for wear periodically. Never use solvent.
What safety precautions should be followed?
Wear a dust mask, protective goggles, and work gloves. Keep your hands away from moving parts. Make sure the tool is unplugged before changing any consumables.
How do I adjust the rotation speed?
The speed is adjustable using the electronic dial located on the sander body. Turn the dial to select a speed between 4,000 and 6,800 rpm, adapted to the material and abrasive grit.
Is the tool compatible with an external vacuum?
The ROS 625DB model comes with an integrated dust bag and is not designed for direct connection to a vacuum. For such use, you would need to opt for the DE model, which is designed for external extraction.
What are the main advantages of this sander?
This sander is lightweight (1.4 kg), easy to handle thanks to its ergonomic handle, and has a dust bag that makes work easier. Its 150 mm Velcro pad and 460 W power provide good performance for finishing work.
What should I do if the sander no longer starts?
First check that the tool is plugged in and that the cable is not damaged. Then check the dust bag, which could be blocking the motor. If the problem persists, the motor carbon brushes must be replaced by an authorized repairer.
