Tips and knowledge about your cordless tool's battery life

Tech Tips

The battery pack is not fully charged when delivered, charge the batteries before you use it. To get the longest possible battery life we recommend:

  • Never store the battery in a discharged condition, recharge it immediately after it has been discharged.
  • If you store your tool for long periods of time without use, recharge the battery every month. This will prolong the battery life.
  • When the trigger is released the sander will stop but continue to stay in active mode for a short time before it automatically deactivates/turns off.
  • When the sander is in active mode the LED light to the right is green.
  • In active mode, the LED light to the left shows the battery status
    • Green: Battery charge level is 75-100%.
    • Flashing green: Battery charge level is 50-75%.
    • Flashing green/red: Battery charge level is 25-50%.
    • Red: Battery voltage too low, tool is not operable.

Please note, in case a battery is damaged physically, with cracks or visible damages, it cannot be returned due to transport regulations.

A better choice for you and the environment

Water-Based Polishes

All polishes that Mirka produces are water-based and produced in Finland. There are many benefits of choosing a water-based polishing compound.

  • Effective permanent removal of scratches - Water-based compounds remove scratches permanently. Solvent-based compounds can lose gloss after cleaning the surface with a degreaser and in some cases, they may only temporarily hide the scratches.
  • Safer for the operator - No hazardous chemicals  
  • Sustainable  - Water-based polishes are better for the environment and do not contain benzene.
