8.2 Choke

GB 460:
The model GB 460 has an auto-
choke that does not need to be operated
manually.
GB 460 C:
When the choke knob (1) is operated, the
air/fuel mixture changes to enable a cold
engine to be started more easily.
11.1)
It should be remembered that the
engine can cool down rapidly in
very cold weather.
If the choke is not deactivated after
the starting procedure, more smoke
will be produced as a result of the
altered air/fuel mixture.
Subsequently, the engine will stall
(engine will be flooded).
Operating the choke:
● Pull out the choke knob (1). This
operates the choke and the engine can
be started.
Deactivating the choke:
● Once the engine is running after the
starting procedure, the choke must be
deactivated immediately by pressing in
the choke knob (1) fully.
9. Notes on working with the
machine

9.1 What material can be processed?

Both soft and hard material can be
processed with the garden shredder.

vegetable waste, flower cuttings, leaves
etc.
– Shredding soft material. (
Hard material:
Tree and hedge cuttings and thick branch
material with side shoots.
– Shredding hard material. (
Tree and hedge cuttings should be
processed when fresh, as the
shredding performance is better
with fresh than with dried-out or wet
material.
9.2 What material cannot be
processed?
Stones, glass, bits of metal (wire, nails,
etc.) or plastic must not be fed into the
garden shredder.
