Select the appropriate polishing pad for your task and screw it onto the M14 spindle. Adjust the speed setting according to the surface type and the polishing compound being used. Apply the compound to the pad or the surface, then start the tool before making contact with the material. Move the polisher in steady, overlapping motions to achieve an even finish.
What to consider before purchase
- Battery and charger are not included and must be purchased separately
- Ensure you have the correct M14-compatible polishing accessories
- Consider the runtime requirements of your project to ensure you have enough battery capacity
For optimal results, always start at a lower speed setting to spread the polishing compound evenly before increasing the speed. Clean your polishing pads regularly during use to prevent residue buildup and ensure a scratch-free finish.
