compost heap should not be processed
using the garden shredder.
8.3 Maximum branch diameter
The data relates to freshly cut branch
material:
Maximum branch diameter:
GHE 355: 35 mm
8.4 Working area for operator
For safety reasons the operator must stay
in the working area (grey area) for the
entire operating period.
To ensure you are not hit by shredded
material that is ejected backwards, you
should not stand directly behind the
garden shredder but slightly to the side of
it (hatched area A).
8.5 Correct way to feed the garden
shredder
Tree and hedge cuttings should be
processed when fresh, as the
shredding performance is better
with fresh than with dried-out or wet
material.

8.6 Display After the garden shredder has been
switched on, the processable shredding
material is indicated on the display (1) by
the following symbols:
Tree and hedge cuttings and
thick branch material with
side shoots.
Organic plant trimmings such
as fruit and vegetable waste,
flower cuttings, leaves, etc.
8.7 Correct machine load
The load on the motor or engine of the
garden shredder must never cause the
speed to drop significantly. Always feed
the garden shredder continuously and
steadily. If the speed drops when working
with the garden shredder, stop feeding the
machine in order to relieve the load on the
motor or engine.
8.8 Overload protection
If an overload of the motor occurs during
operation, the built-in overload protection
device automatically switches off the
motor.
The garden shredder can be started up
again after a cooling period of
approx. 10 minutes. Frequent triggering
of the overload protection may be
attributable to the following causes:
– Unsuitable electric cable (Ö10.1)
– Power overload
– Machine overloaded due to excessive
quantities of shredding material or blunt
blades
8.9 If the cutting unit of the garden
shredder is blocked
If the cutting unit of the garden shredder
becomes blocked during shredding,
immediately switch off the motor and
disconnect the power cable. Then remove
the feed chute and eliminate the cause of
the fault.
9.1 Motor restart inhibitor
The machine can only be started via the
switch and not by plugging the electric
cable into the mains socket.
Risk of injury!
The inclined blade unit can cause
branches to kick back. In order to
prevent injuries caused by
kickback, the garden shredder must
be fed in the correct manner. If the
garden shredder is fed from the
rear (i.e. the operator is standing in
the working area (Ö8.4)), the
branch material should be inserted
at a slight angle and guided along
the left-hand chute wall to the blade
unit in accordance with the
symbol (1).
When feeding, note the maximum
branch diameter specified. The
large feed opening is designed to
better accommodate branches with
numerous side shoots and twigs.
The symbol given in the display is
only meaningful when the motor is
running. For this reason, switch on
the garden shredder before
checking the display. (Ö10.4)
