Carry out a visual inspection before each startup.
The camera symbol on the following page refers to the illustrations on Page 4–7.
Adjusting the cutting height

Caution – Risk of injury!
Adjust the cutting height only with the motor switched off and when the mower blade has come to a standstill.

• Always set all the wheels to the same cutting height.
• Cutting height adjustment depends on the particular model.

Axle adjustment or central adjustment ( 1, 2)

1. To release the lever, press to the side and hold.
2. Push the lever to the left or right to select the desired cutting height.
3. Let the lever click into position.
4. Check that all wheels are set to the same position.

Quick adjustment of individual wheels or axle adjustment ( 3)

1. To release the lever, press to the side and hold.
2. Push the lever to the left or right to select the desired cutting height.
3. Let the lever click into position.
4. Check that all wheels are set to the same position.

Central axle adjustment ( 4)

1. Place a thumb at each end of the axle.
2. Place the fingers under the mower housing.
3. Using both thumbs, press the axle out of its present height setting notch.
4. Using both thumbs, push the axle to the desired height setting notch, then allow it to engage.

   Mowing with the grass catcher

Caution – Risk of injury!
Attach/detach the grass catcher only when the motor is switched off and the mower blade has come to a standstill.
6. Lift the deflector plate and insert the grass catcher in the holders ( 6).

Important!
Only a correctly attached and undamaged grass collector offers sufficient protection against flying objects!

Fill level indicator
The fill level indicator is pushed upward by the air flow when mowing ( 5a).
If the grass catcher is full, the indicator points to the box ( 5b). The grass catcher must be emptied.

Emptying the grass catcher

1. Lift the deflector plate.
2. Unhook the grass catcher and pull backward to remove ( 6).
3. Empty the grass catcher.
4. Lift the deflector plate and insert the grass catcher in the holders ( 6).

Mowing without the grass catcher

Caution!
Only work without the grass catcher if the deflector plate torsion spring is working correctly.
The deflector plate is held to the mower housing by spring force. This causes the mowed grass to be thrown backward and downward.
Mulching with the mulch kit (optional)
When mulching, the grass cuttings are not collected, but are left on the lawn. The grass mulch prevents the soil from drying out, and supplies it with nutrients.

The best results are obtained by cutting back regularly by about 2 cm. Only young grass with a soft leaf texture decomposes quickly.

• Grass height before mulching: 8 cm maximum
• Grass height after mulching: 4 cm minimum
  Adapt your walking pace to the mulching process, do not walk too fast.
  Inserting the mulch kit

Caution – Risk of injury!
Insert/remove the mulch kit only with the motor switched off and when the mower blade has come to a standstill.

1. Remove the grass catcher ( 6).
2. Lift the deflector plate and insert the mulch kit in the outlet shaft ( 7).
   It must lock into place.
   If the mulch kit is not locked into position, both the mulch kit and the mower blade may be damaged.

Removing the mulch kit

1. Lift the deflector plate.
2. Release the lock on the mulch kit ( 8/1).
3. Pull out the mulch kit ( 8/2).

Mowing with side discharge unit (option)

Important – Danger of injury!
Attach or remove the side discharge unit only when the motor has been switched off and the cutting blade is at a standstill.

Fitting the side discharge unit

1. Remove the grass collector and fit the mulching kit.
2. Press the release lever on the cover of the sidedischarge unit ( 9/1).
3. Open and hold the cover of the side discharge unit ( 9/2).
4. Fit the side discharge tunnel ( 9/3).
5. Slowly close the cover.
   The cover secures the side discharge tunnel to prevent it from falling out.

Removing the side discharge unit

1. Open and hold the cover of the side discharge unit ( 9/2).
2. Remove the side discharge unit and close the cover ( 9/3).
   Starting the motor
