Blockage Protection : If the aerator cylinder is blocked, e.g.
by a foreign body, immediately release the starting lever. If the
blockage lasts longer than 10 seconds and the starting lever
has not been released, blockage protection is activated. In this
case immediately release the starting lever. The Aerator can
be switched on again after cooling down for approx. 1 minute.
DANGER OF INJURY !
A
If blockage protection is activated and the starting
lever is not released, the Aerator starts again auto-
matically after approx. 1 minute.
DANGER ! The aerator cylinder can cause injuries !

V Prior to maintenance, unplug from the mains and
wait until the Aerator drum has stopped.
V Wear working gloves for performing maintenance.
The Aerator should be cleaned after each time it is used.
Risk of injury and physical damage !
A
V Do not clean Aerator under running water
(particularly under high pressure).
V Do not use hard or pointed objects for cleaning
the Aerator.
v Remove grass and deposits from wheels, aerator cylinder
and housing.
The Aerator is subject to wear in use due to the way in which it
works. The more intensively the Aerator is used, the greater the
wear on the knives.
Hard or very dry ground accelerates wear as does excessive use
of the Aerator.
If the results of your work with the Aerator become increasingly
worse due to knife wear, the aerator cylinder can be adjusted
twice.
The aerator cylinder has 4 adjustment positions :
• Transport position
• Aerating position 1 :
• Aerating position 2 :
First adjustment position after knife wear (aerator cylinder
lowered by 3 mm).
• Setting 3 :
Second adjustment position after knife wear (aerator cylinder
lowered by a further 3 mm)
Push wear compensation lever
and move to the position required.
Note : Wear adjustment is not used for height adjustment.
Adjustment of the aerator cylinder without visible wear can
cause damage to the aerator cylinder or overload the motor.
