the Aerator drum has stopped.
v Wear working gloves for performing maintenance.
Cleaning Aerator:
The Aerator should be cleaned after each time it is used.
DANGER! Risk of injury!
Risk of injury and risk of damage to the product.
v Do not clean the product with water or with a water jet
(in particular high-pressure water jet).
v Do not use hard or pointed objects for cleaning the Aerator.
v Remove grass and deposits from wheels, aerator cylinder and housing.
Adjusting for wear [ Fig. M1 ]:
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

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.
6. STORAGE
To put into storage:
To save space the aerator can be folded up by releasing the wing nuts.
Take care during this process that the cable does not become
trapped.
v Store the Aerator in a dry, closed room to which children cannot gain
access.
Transport:
1. Switch off motor, unplug from the mains and wait until the aerator
cylinder stops.
2. Move the wear compensation to the transport position and raise the
aerator when transporting it over sensitive surfaces, e. g. tiles.
