Following assembly, check that the
feed chute ATO 400 is correctly
engaged in both openings in the
basic unit.
8. Notes on working with the
machine
Tree and hedge cuttings should be
processed when fresh, as the
shredding performance is better
with fresh than with dried-out or wet
material.
The size of the feed opening of the
branch guide serves only to better
accommodate branch material with
side shoots and does not indicate
the maximum permitted diameter of
the shredding material.
Risk of injury:
To ensure you are not hit by
shredding material that is ejected
backwards when processing hard
material (branch guide (1) folded
out), you should stand slightly to
one side of the garden shredder
(see grey area X) and not directly
behind it.
