with the hands or fingers.
Never put your hands or feet
between the housing and ground.
Danger of burns!

own weight.

cutting height" position (=centre
position).
● Reducing the cutting height:
The cutting level is reduced by pushing
on wheel fork (1).

swivelling axle (4) of the front wheel
from above using the other hand until
the desired cutting height is reached.
● Checking the cutting height:
Select the cutting height (cutting levels
1 to 5 as shown) so that the cutting level
at the rear wheel is the same as the
cutting level at the front wheel. The
housing must be parallel to the ground.
