Regular maintenance ensures the longevity and optimal performance of your tool. Always unplug the tool before performing any maintenance.

7.1 Lubrication (Greasing)

The hammer mechanism requires periodic lubrication. Locate the External Grease Filler cap, unscrew it using the provided wrench, and apply a small amount of the supplied grease. Re-secure the cap tightly.

7.2 Carbon Brush Replacement

Carbon brushes wear down over time and need replacement. When the tool's performance decreases or it stops working, the brushes may need to be checked. Unscrew the brush covers (located near the motor housing), remove the old brushes, and insert the new ones (2 pcs spare included). Ensure they are seated correctly before replacing the covers.

7.3 Cleaning

Keep the ventilation openings clean and free from dust and debris. Use a dry cloth to wipe down the tool after each use. Do not use harsh chemicals or abrasive cleaners.
