Adjusting for wear:
M
1. Remove grass and deposits from wheels, aerator cylinder
and housing.
2. Remove dirt from air inlets on the 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.
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.
The aerator cylinder has 3 adjustment positions:
• Position 1: Position set at the factory
• Position 2: First adjustment position after knife wear
(aerator cylinder lowered by 3 mm)
• Position 3: Second adjustment position after knife wear
(aerator cylinder lowered by a further 3 mm)
