Information on all types

Wear on the blades will make it necessary to re-adjust the depth of cut at a later date. An optimum working depth is obtained when the blades of the cutter are inserted 2–3 mm into the ground.

If the working depth is too deep, this can overload the scarifier and cause damage. Ensure that the depth of cut setting is correct.

Figure 3a/b

„Unscrew wheels (A) and move to the appropriate height setting. Screw on wheels tightly.

or Figure 3c

„Set height adjustment lever (depending on model) according to the wear on the blades. Settings C, D, E are not required until the blades are worn. Depending on the degree of wear, gradually set the blades lower, starting at C.

3. Power cord

Figure 4

„Attach power cord to the cord grip.

„First plug the mains plug into the switch/plug combination on the unit and then into a 230 V socket.

Figure 5

„Keep the appliance on an even surface with little or the shortest possible grass.

„Tilt the unit backwards slightly until the front wheels are off the ground (Fig. 5a) or move the height adjustment lever to position A to prevent the blade shaft from touching the ground (Fig. 5b).

„Press and hold down the locking button (Fig. 5c).

„Pull and hold the switch lever, release the locking button (Fig. 5c).

„Slowly lower the front of the unit until the front wheels are touching the ground again or move the height adjustment lever (depen- ding on model) forwards to the first working depth setting (B, first notch) (Fig. 5b).

Note

When the cutter deck is in contact with the ground, the unit can move.

5. Stopping the engine

„Release switch lever (Fig. 8a).

The motor and the cutter deck stop after a short time.

6. Scarification

Figure 6

„Start the engine as indicated.

„Push the scarifier along parallel strips of the lawn.

„Place the power cord in large loops on the ground.

7. Detaching and emptying the grass sack

(Optional, depending on model)

Figure 7

„Release switch lever and wait until the motor stops.

„Lift the deflector flap and unhook the grass sack.

„Empty out the contents.

8.Working without the grass sack

Whenever you detach the grass sack, the deflector flap drops down. When scarifying without the grass sack attached, the cuttings are ejected straight onto the ground.

9. After finishing work

„Stopping the engine.

„Pull the mains plug out of the unit and the socket.

„Empty grass catcher.

„Leave the motor to cool down (approx. 30 minutes) before cleaning, servicing, storing or shutting down the unit.

About aeration

In order that a healthy lawn can develop in the spring, it is necessary for greater amounts of air to pene- trate the area around the roots of the grass. During this period the lawn must be scarified more frequently than in the summer.
