• Shut off the power unit before attaching or
removing the collection box.
• Keep all guards and deflectors in place and
in good working condition.
Operating and maintenance safety
• Make sure that the hopper funnel is empty
before you start the shredder.
• Keep your head, hair and body away from
the intake opening.
• Do not reach into the hopper funnel during
operation. The shredder will continue to run
for a short period after you switch it off.
• Always make sure you are standing in a firm,
balanced position. Do not lean forwards,
and never stand above the shredder when
inserting materials.

8
• Make sure that the material inserted into
the shredder does not contain hard objects
made of metal, stone, glass or similar.
• Do not use the shredder in the rain or in bad
weather. Work in daylight or under good
artificial lighting conditions.
• Do not operate the shredder when you are
tired or distracted, or under the influence of
alcohol or medication. Always take a break
when you need one and be sensible about
how you work.
• Disconnect from the mains supply (i.e.
remove the plug from the mains socket) in
the following circumstances:
• when you are not using the device
• transporting the shredder or leaving it
unattended
• before releasing a jammed blade

Note: If the shredder is making unfamiliar
noises or vibrations, or has struck a foreign
object, disconnect the power cable and ensure
any damage is checked and/or cleared before
starting up again.
• Do not allow shredded material to accumulate
near the ejection area. This may otherwise
hinder proper ejection and force the material
back up through the funnel.
• Do not transport or tip the shredder with the
motor running.
• Keep hands, other body parts and clothing
out of the filling chamber and ejection channel,
and away from other moving parts.
• In the event of blockages in the machine intake

• Do not overload your device. Work only within
the indicated range of performance. Do not
use low power machines for heavy-duty
work. Do not use your device for purposes
for which it has not been designed.
• Only switch the shredder off once the hopper
funnel is completely empty. The shredder may
otherwise clog up and not be able to start
afterwards.
• Do not attempt to repair the shredder yourself
unless you are qualified to do so.
CAUTION! The following states how to
avoid accidents and injuries due to electric
shock:
•

Blade adjustment
Maintenance
The pressure plate – what is it?
• The pressure plate 20 is used on silent shredders to finely adjust
cutting performance and to improve cutting performance as the roller
blade 21 and pressure plate wears.
• During adjustment, the pressure plate can be moved towards or away
from the rotating roller blade. The pressure plate can be moved away
from the roller blade to help clear blockages. During adjustment, to
improve cutting performance, the pressure plate is moved towards the
rotating roller blade.
• The roller blade is designed to cut into the pressure plate to ensure that
there is no gap between the blade and the plate. The pressure plate is
sacrificial to the roller blade and will be reduced in size over time. If you
regularly adjust the pressure plate then the branches to be shredded
will be cut through properly. Eventually, over time, you may need to
replace the pressure plate.
Advancing the pressure plate to improve cutting performance
To do this, the pressure plate is advanced towards the roller blade while
the roller blade is rotating. This ensures that only the circular path of the
tips of the blade cut into the pressure plate.

Removing blockages
WARNING! Always switch the product off, disconnect it from the
power supply and let the product cool down before performing
inspections, maintenance and cleaning work!
In case of more stubborn blockages, you may have to clear material from
inside the cutter housing. Proceed as follows:
• Remove the four Allen screws 14 on the housing cover 16 .
• Remove the cover. This may require light jerking movements.
IMPORTANT! Do not advance the plate while the blade is stationary.
If the pressure plate is adjusted while the blade is stationary, the plate
can be positioned between the tips of 2 of the blades and too far within
the blades and the circular path of the blade tips. This could damage the
pressure plate or the shredder.
Using the adjustment knob correctly
• Ensure the shredder inlet is free from material to be shredded.
• Start the machine normally in the down direction, this is the direction
required to shred material.
• The shredder roller blade should rotate freely; it has a low speed of
rotation only once per second.
• Slowly rotate the adjustment knob
19
clockwise a ½ turn. The pressure
plate is advanced towards the blade while the blade is moving.
• If the roller blade continues to rotate without a grinding noise, advance
another ½ turn.
• When you here a grinding noise, the pressure plate is being cut by the
roller blade; your shredder is now correctly set up for a good cut. You
should see small aluminium shavings from the pressure plate in the
collection box.
• Check cutting performance by feeding a woody branch into the
shredder - it should be cut through correctly into pieces approximately
3cm in length.

20
• Remove any further blockage from the equipment.
• When fitting the cover 16 back on, ensure it is fitted correctly so that
the blade shaft 18 , the pressure plate rod 17 and the four recesses
15 for the Allen screws are all correctly aligned and fit smoothly into
the recesses on the cover. Ensure that the cutting pressure plate is
positioned correctly.
• Screw on the housing cover 15 firmly with the four Allen screws 14 .
