Why my Bosch Rotak 36 LI won't start?

  Michelle AllisonAug 14, 2025
  If your Bosch Lawn Mower fails to operate, several factors could be the cause. It might be due to a possible clogging. To resolve this, remove the isolator key and check underneath the garden product, clearing out any obstructions as necessary, and always wear gardening gloves. Alternatively, the battery may not be fully charged, properly inserted, or it could be too hot or cold. Grass that is too long can also prevent operation; in this case, increase the height of cut and tilt the garden product to reduce the starting load. If the motor protector has activated, allow the motor to cool and increase the height of cut. Ensure the isolator key is correctly fitted. There may also be a short delay, so hold the On/Off switch for 1 – 3 seconds to start the motor.

Why area of cut not large enough with Bosch Rotak 36 LI Lawn Mower?
- E
  Erica KramerSep 3, 2025
  If the area cut by your Bosch Lawn Mower isn't large enough (battery duration), this could be due to several reasons. The height of cut might be too low; increase it and walk slower. If the grass is too high, increase the height of cut and walk slower. Wet or damp grass can also reduce the area of cut, so wait until the grass is dry and walk slower. If the grass is dense, increase the height of cut, walk slower, and cut more frequently.

Check the mains voltage and, if necessary, have the battery charger checked by an authorized customer service station for Bosch power tools.
