ble lifting gear and pull the device up using
a crane until the engine support rests on

Cleaning the device

After each use, you should clean the device
thoroughly, especially the bottom side and the
blade.
Stuck grass or dirt affect the grass discharge

components at the silencer are clean.
For cleaning use a hand brush. Remove stub-
born soiling with a wooden or plastic spatula.

Do not rinse off the device with a water jet or
high pressure cleaner! Do not use aggressive
cleaning agents.
