–  Switch of the motor and wait until the cutters come to a stop.
–  Lift the ejection flap.
–  Remove the full grass bag from the scarifier by the carrying strap – the ejection

flap closes automatically.

– Shake out of the grass bag thoroughly, holding it by the carrying strap and bottom.

NOTE
The device can be used on banks and slopes with a gradient of up to 46% (25°
angle).
For safety reasons, however, we urgently recommend you do not exploit this
theoretical performance potential. Always make sure you have a firm stance.
Manually guided scarifiers should never be used for slopes with a gradient in
excess of 26% (15° angle of slope). Stability may be lost!

Position the cable in such a way that the machine can pull it along easily over the lawn

surface that has already been worked. When the machine turns the cable grip
automatically positions the cable to the other handle side. Ensure that the cable is kept
well away from the cutters and that no loops are formed. Check the mains cable
regularly for signs of damage and only use it in proper condition.

Checking operating safety

The scarifier is equipped with a motor stop device.
Before every scarifying job, make sure that the motor stop safety control bar/lever is
working perfectly. When the control bar/control lever is released the motor must switch
off and the cutting tool must come to a standstill. Note! The cutting tool runs on for a
while. If this is not the case, please consult your nearest authorised workshop.
After release, the bar/lever must always return to the position shown in the "component
description" diagram.
If this is not the case, it must be checked immediately by an authorised workshop.
Machine safety and protective devices must not be manipulated or disabled.
Make sure that all protective devices have been attached properly and are not
damaged.
Check the upper part of the bar (insulation) for damage. If the casing should be
damaged, contact the nearest authorised workshop without delay, since otherwise
injuries (electric shock) can occur through touching the live parts.
Also check machine screws and nuts for a firm fit every 10 operating hours and tighten
if necessary.
To avoid danger, check the condition and tight fit of the cutter blades before every
scarifying job (refer to the chapter “Cutter blade shaft care” for more details).

WARNING
Always have a specialist workshop carry out work on the cutter blade shaft, open
or remove any covers connected with the device, since an insulation protection
test must be always be carried out following repairs or maintenance work on

insulated parts (e.g. cutter blade shaft, attachment parts, covers) in line with
standard DIN EN 60335.
In addition, a wrongly assembled cutter blade shaft can lead to parts becoming
loose and causing serious injuries.

If the cutter blade shaft becomes blocked e.g. by colliding with an obstacle or through
foreign objects, have an authorised workshop check whether any parts of the scarifier
are damaged or deformed. Always have any necessary repairs done by an authorised
workshop too.
If the machine starts to vibrate unusually heavily or to make unusual noises, please
have it checked immediately by an authorised workshop.

The time at which scarifiers may be used varies from region to region. Please ask the
relevant authorities before using your scarifier.

Tips on caring for your lawn (Illustration M )

When using the machine, always guide it in straight lines at medium walking speed.
Due to the forward direction of rotation of the blade shaft, only a slight pushing force is
required. Depending on the properties of the surface, it may be necessary to hold the
machine back against the working direction. Avoid moving in tight curves.
On very mossy and weedy lawns, it is advisable to apply the scarifier a second time, at
right-angles to the first working direction. When using the machine without a grass
collector, removes the loose grass from the lawn before the second run. Loose grass
lying on the lawn will have an adverse effect on the result, put an additional strain on
the machine and make the work unnecessarily difficult for the user (stronger pushing
forces).
Loose materials can best be removed by vacuuming with a TurboStar lawn mower or
manual raking.
