Switching off
Only switch the motor off when the mul-
cher is completely empty. Other-wise
the blades can become jammed when
the appliance is re-started.
Correct loading of the motor
The garden mulcher may only be loaded
so that the motor speed is not greatly
reduced. If an overload should occur,
the incorporated thermal overload
switch will switch the motor off automati-
cally.
Important: To avoid overheating the
motor, the motor should be allowed to
cool off for approx. 10 mins before it is
re-started. If the mulcher is jammed,
switch the motor off immediately and
disconnect the electrical power supply.
Then investigate and eliminate the
cause of the breakdown.
If the thermal overload switch trips
repeatedly, the following causes could
be present:
• unsuitable connecting lead
(see: electrical power connection),
• circuit overload,
• appliance overload due to excessive
material feed rate or blunt blades.

Maintenance
Cleaning
Clean the appliance thoroughly after
use. Use the appliance sympathetically
to avoid breakdowns and to prolong its
lifetime. Use a commercially available
product to protect the mulching tools
and the mulch container (i.e. rapeseed
oil) against corrosion.
The electric motors are splash proof and
have a labyrinth seal with an additional
seal ring on the tool shaft (see illus.).
This should be regularly inspected (i.e.
during blade sharpening).
Only use a brush to clean the appliance.
Never use a water jet or high
pressure hose on motor components,
seals, bearings, and electrical compo-
nents (i.e. switches). It could result in
expensive repairs!
The electric motors require no mainten-
ance.
Motor seal with labyrinth seal and
seal ring (1).
The seal ring is accessible after the cut-
ting assembly and the blade mounting
have been removed.
Important: The power supply must be
disconnected before any maintenance
or operation is performed on the mul-
ching tools. Never touch any part of the
cutting assembly while it is in motion,
wait until it is at a complete standstill.
