Important!
For transport move the lever for set‐ ting the depth to the highest position. Tips for
proper working
It is recommended that you overlap scarifying paths a little. Try to scarify in straight lines for a nice, clean
look. Insodoing, the aeration swaths should always overlap each other by a few centi‐ meters in order
to avoid bare strips.
As soon as grass clippings start to trail the scarifiers, it is time to empty the grass basket.
Important!
Before taking off the grass basket, switch off the motor and wait until the roller has come to a stop.
To remove the grass basket, lift up the ejector flap with one hand, while unhooking the basket with the
other.
How frequently you should scarify your lawn is determined primarily by the speed at which the grass
grows and the hardness of the soil.
Keep the underside of the equipment clean and remove soil and grass build‐ up. Deposits make it
more diffi cult to start the aerator and decrease the quality of the scarifying.
Always scarify along inclines (not up and down). Switch off the motor before doing any checks on the
roller.
Important!
The roller rotates for a few seconds after the motor is switched off . Never attempt to stop the roller. In the
event that the rotating roller strikes an object, immediately switch off the equipment and wait for the roller
to come to a complete stop. Then inspect the condition of the roller. Replace any parts that are
damaged.

Important!
Never work on or touch conducting parts on the ignition unit with the engine running. Always pull the
spark plug boot from the spark plug before starting any work of care or maintenance. Never perform any
work on the machine while it is run‐ ning. Any work not described in these Operating Instructions must be
performed by an authorized service workshop only.

9.1 Cleaning

The scarifier should be cleaned thoroughly eve‐ ry time after it has been used. This particularly
applies to its underside and the blades. To do so tip the scarifier slightly on to its side and remove the
dirt.
Important. Before you tip the equipment, the pet‐ rol tank must be emptied to prevent petrol
leaking out. Ideally you should use a conventional petrol extraction pump for this purpose.

9.2 Servicing

Checking the oil level
Set the equipment down on a flat, level surface.
Unscrew the oil dipstick by turning it anti‐ clockwi‐ se. The oil level must be as shown in Figure 10.
