The carbon dioxide (CO2) emission value determined by an EU type-approval procedure for this machine is: 984.17 g/kWh
⚠️ CAUTION! Hearing damage! Wear ear protection.
Levels of noise and vibration were determined according to the standards and regulations in the declaration of conformity.
The specified total vibration value and the stated noise emission value have been measured according to a standardised test method and can be used to compare one device with another. The specified total vibration value and the stated specified noise emission value can also be used for a provisional assessment of the load.
⚠ WARNING! The vibration and noise emissions may deviate from the specified values during actual use of the device, depending on how the
device is being used. Safety measures for the protection of the operator are to be determined that are based on an estimate of the actual vibration load under the real operating conditions (for this, all parts of the operating cycle are to be taken into account, for example, times in which the device is turned off, and those during which it is turned on but running without a load).
Keep noise and vibration to a minimum!
- Only use machines that are in perfect working order.
- Maintain and clean the machine regularly.
- Adapt your working method to the machine.
- Do not overload the machine.
- Have the machine inspected thoroughly, wherever possible.
- Switch off the machine when it is not in use.
- Wear gloves.
⚠ WARNING! During prolonged work, the vibration in the operator's hands can lead to circulatory disorders (Raynaud's syndrome).
Raynaud's syndrome is a vascular disease in which the small blood vessels in the fingers and toes seize up. The affected areas are no longer supplied with sufficient blood and therefore appear extremely pale. Frequent use of vibrating products can cause nerve damage in people whose blood circulation is impaired (e.g. smokers, diabetics). If you notice any unusual impairment, stop work immediately and consult a doctor.
Pay attention to the following instructions to reduce dangers:
- Keep your body and especially your hands warm in cold weather.
• Take regular breaks and move your hands while doing so to promote blood circulation.
- Keep machine vibration to a minimum by regular maintenance and fixed parts on the machine.
• Take rest periods when needed and limit working time to the minimum necessary.

Mulching kit
Difference between mowing lawns and mulching lawns
When using the mulching kit (32), the grass clippings are not collected in a catcher but are instead shredded and spread across the lawn. The nutrients contained in the clippings are thus left to be broken down by soil organisms and form a nutrient cycle. Mulched lawns therefore need to be fertilised much less frequently. As a basic rule, the lawn has to be mowed relatively often so that only small amounts of mulch remain on the lawn. It is therefore best to mulch the lawn at least once a week and to adjust the mower so that only about 40 % of the total height of the lawn is left as mulch. If the mulch remains visible on the lawn (for example when cutting the lawn for the first time of the year or during strong growth), the grass catcher (22) should be used.
Inserting the mulching kit
Procedure (Fig. D)
- Remove the grass catcher (22), if fitted.
- Lift the impact protection (25).
- Slide in the mulching kit (32). The lock (36) on the mulching kit (32) engages.
- Fold the impact protection (25) back onto the mulching kit (32).
Removing the mulching kit
(Fig. D)
-
Lift the impact protection (25).
-
Press the lock (36) on the mulching kit (32).
- Remove the mulching kit (32).
- Fold the impact protection (25) onto the machine housing (35).
Setting the cutting height
Lawn care
Regular mowing stimulates the grass to an increased leaf formation, while at the same time killing weeds. As a result, the lawn becomes denser after each mowing and the outcome is a healthier lawn in general. The first cut takes place roughly in April when the grass is about 70-80 mm high. During the main growing season, the lawn is mowed at least once a week.
Selecting the correct cutting height
A high cutting height should be selected for the first mowing of the season. The correct cutting height is between 25 and 40 mm for an ornamental lawn and about 40 to 60 mm for a utility lawn.
The machine has 7 cutting heights:
• 25/35 mm - low cutting height
- 45/55/65 mm - medium cutting height
- 70/75 mm - high cutting height
Procedure (Fig. E)
- Grasp the cutting height adjustment lever (19) and push it to the side.
- Move the cutting height adjustment lever (19) past the ratchet mechanism to the desired cutting height.
- Press the cutting height adjustment lever (19) to the side to engage it.
Fitting the side ejector chute
Notes
- When using the side ejector chute, the cut grass falls sideways onto the lawn.
Procedure (Fig. F)
- Remove the grass catcher (22) (see Removing the grass catcher, p. 42).
- Insert the mulching kit (32) (see Inserting the mulching kit, p. 43). This prevents the clippings from accumulating in the ejector chute.
- Activate the lock (37) and lift the side ejector flap (17).
- Hook in the side ejector chute (18).
- Place the side ejector flap (17) on the side ejector chute (18). The side ejector flap (17) holds the side ejector chute (18) in position.
Removing the side ejector chute
(Fig. F)
- Lift the side ejector flap (17).
- Unhook in the side ejector chute (18).
- Put down the side flap (17) on the machine housing (35). You will hear the lock (37) click into place.
