For those who want to eject the blades, it is not easy to understand instructions. So for you not to blow your pretty mower:
1 / Keep the mower head vertically with both hands and on / off button facing you.
2 / Retract the ceramic blade with the wheel at the position 2.0mm to avoid damage by pushing. You never know with musclors.
3 / Position both thumbs vertically at the name "REMINGTON" ready to push the blades back (to you).
4 / Check that your two index is firmly positioned at the rear base of the striated gray plastic extension part of the stainless steel blade. You can not go wrong.
5 / Push the blades before you firmly but gently, and miraculously, the two blades and serrated plastic part that serves as their support tilt backwards with an ejection effect.
Update - Sniff! After some beautiful years of loyal service, our beloved mower passed away. I dismounted infortunément but I was unable to bring her back to life. Was batteries or electronics?
