increased. We recommend aerating the lawn, depending on the
condition, every 6 – 8 weeks.
To achieve good results and to extent the life of the aerator
drum, the lawn should be mowed before aerating (approx. 2
cm).
Install the aerator drum (see "Assembly")
Fight the moss with a commercially available agent before
aerating.
Proceed as described under "Scarifying".

Blade replacement
Wear protective gloves when working with
the blades. Risk of injury!
Worn blades reduce the performance of the device and put
excessive strain on the motor. Therefore check the condition of
the blades before each use. If necessary, have the blades
sharpened by an expert or replaced by new ones.
The blades can be turned. To turn the blades, proceed
as follows:
Remove the cylinder head screws (34) on the bearing
holder (33) using the supplied installation wrench (42).
Remove the scarifier drum (29).
Remove the hexagon nut (b) and remove the cover (c),
flange (d), blades (30) and the spacer rings (e) from the
axle.
Turn the blades or insert new ones and install the drum
again in the opposite sequence.
Replace worn or damaged blades only as a set to
avoid imbalances!
Retighten the hexagonal nut and place the drum in the
device.

Pull the mains plug prior to transport.
The drum can be damaged during transport, e.g. on hard
ground, even when the motor is switched off. Therefore set the
work depth of the drum to position 1 during transport.

Pull out main plug.
Store unused equipment in a dry, locked place out of the
reach of children.
In case of extended storage (e.g. during winter) ensure that
the device is protected against frost and corrosion.
Before extended storage, please observe the following to
increase the service life of the device and to ensure smooth
operation:
thoroughly clean the device
Treat metal parts after each use against corrosion using
an environmentally friendly biologically degradable spray
oil.
Never use any grease!
To facilitate space-saving storage of the device,
you can fold down the handle hoop. For this, loosen the
star grips (6) so that the handle hoop (1) and the
connecting bars can be swung in.
