Gardena EVC 1000/30 manual Trouble-Shooting, Adjusting for wear, Replacing aerator cylinder

G

Adjusting for wear:

L

K

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)

The openings for the retainers on the wheels must be free of dirt.

1.Press retaining spring K together and pull out the adjustment unit L approx. 6 mm.

The wheel is no longer fixed to the axle.

2.Turn adjustment unit L 90° to the next highest position.

3.Press the centre of the adjustment unit L until the retaining spring K audibly snaps into the new position.

The wheel is now fixed to the axle in the new position.

4.Adjust the wheel on the other side to the same position.

Both wheels must always be in the same position.
