Operation of the rear wheel drive (only with connectible autodrive)
(figure G )

The rear wheel drive is switched on and off using the drive control bar (1) on the upper
guide bar (2) while the engine is running:
– Pull and hold the drive control bar = mower moves.
– Release the drive control bar = mower stops (0 position).
The drive control bar must always be firmly pulled towards the top bar. Inappropriate
actuation leads to wear of the transmission. The higher resistance of the bar in the initial
condition is desired in order to make faulty operation more difficult.
NOTE
The rear wheels click when the mower is pushed forward.

Operation with grass collecting bag
WARNING
When operating the equipment with a grass collecting bag, the bag must be
completely assembled and in technically perfect condition.
When using the machine, ensure that the collecting bag is emptied in good time.
IMPORTANT
Do not clean the grass collecting bag with hot water!

Emptying the grass collecting bag (figure L )
– Switch off the engine.
– Lift the ejection flap.
– Remove the full grass collecting bag from the mower by the carrying strap – the
ejection flap closes automatically.
– Shake out the grass collecting bag thoroughly, holding it by the carrying strap and
the moulded handle on the bottom.
Operation without grass collecting bag

WARNING
When mowing without grass collecting bag, the ejection flap on the mower housing
must always be closed (flap down).

Using the machine on slopes
ATTENTION
The mower can be used on banks and slopes with a gradient of up to 46%
(25° angle). Any steeper slopes can lead to engine damage. For safety reasons,
however, we urgently recommend you do not exploit this theoretical performance
potential. Always make sure you have a firm stance. Walk-behind lawn mowers
should never be used for slopes with a gradient in excess of 26% (15° angle of
slope). Stability may be lost!
Checking the oil level
Check oil level before each mowing job Y1 . Never let the engine run with too little or too
much oil. Irreparable damages could occur.
Checking operating safety
The lawn mower is fitted with an engine stop device.
Before every mowing job, make sure that the engine stop safety control bar is working
perfectly. When the control bar is released, engine and cutter bar must come to a
standstill within three seconds.
After release, the bar must always return to the position shown in the “Description of
components” diagram.
If this is not the case, it must be checked immediately by an authorised workshop.
Risk of injury!
If the stopping time of the blade is longer, stop using the device and take it to an
authorised workshop.
Measuring the stopping time
After starting the combustion engine, the blade rotates and a wind noise can be heard.
The stopping time corresponds to the duration of the wind noise after the combustion
engine has been switched off; it can be measured with a stopwatch.
Machine safety and protective devices must not be manipulated or disabled.
The correct operation of the autodrive control bar must also be checked before each
mowing job. When the autodrive control bar is released, the machine must come to an
immediate standstill. If this is not the case, it must be checked immediately by an
authorised workshop.
Make sure that all protective devices have been attached properly and are not damaged.
To avoid any risk, always check the condition and firm seating of the blade before each
mowing job. The blade fastening screw must always be tightened by an authorised
workshop. If the blade screw is tightened excessively or insufficiently, blade coupling and
cutter bar may be damaged or get loose, which can lead to serious injuries. A worn or
damaged blade must imperatively be replaced. (See chapter “Maintenance of the cutter
bar”).
Check the blade coupling for wear and a tight fit every 10 operating hours. Also check
device screws and nuts for a firm fit and re-tighten, if necessary.
Make sure the spark plug connector is fitted tightly. Risk of electric shock. Never remove
the plug connector with the engine running. Risk of electric shock. Only remove the plug
connector if the engine has cooled down. Risk of burns.
If the mower becomes blocked e.g. by colliding with an obstacle, have an authorised
workshop check whether any parts of the mower are damaged or deformed. Always have
any necessary repairs done by an authorised workshop too.
If the machine starts to vibrate unusually heavily or to make unusual noises, please have
it checked immediately by an authorised workshop.
Time restrictions
In Germany, the time for the operation of lawn mowers is regulated in the “32nd
Ordinance for the Implementation of the Federal Immissions Act (32nd BimSch- V)”.
In addition, regional restrictions are possible (e.g. to observe the afternoon quiet hours);
related information is available from the competent municipal authority.

Tips on caring for your lawn

Mowing (figure M )
WARNING
Remove all foreign bodies (stones, wood, branches, etc.) from the lawn before any
mowing; however, you should still keep an eye out for objects lying around while
mowing.
You can get an introduction to lawn care from your dealer on request. Information and
instructions for mowing can also be found on the manufacturer's website.
Mulching
Your lawn mower can be equipped with a mulch plug. The corresponding conversion kit
to the mulch system is included upon delivery.
What is mulching?
During mulching, the lawn is cut and the cut stalks are simultaneously repeatedly
shredded by the special mulching knife. This mulch knife straightens the stalks of grass
and cuts the stalks into very short pieces, which are then evenly distributed over the lawn.
The grass sections can now dry out and rot more quickly, thus promoting humus
formation. In this way, the soil is fertilised in a natural manner and also protected from
drying out. The collection and disposal of the cut material is no longer necessary.
The mulching concept thus substantially supports the ecological cycle.
How to achieve a perfect lawn cut?
When using the mulch mower, the grass height to be cut should not exceed 10 cm, if
possible. In one pass, a maximum of 1/3 of the grass height is cut down. If a positive
result is not achieved, it may be necessary to mulch two times in succession.
Depending on the type of lawn and the intensity of growth, the lawn should be mown at
regular intervals. Especially during strong growth phases, mulching requires more
frequent mowing than the traditional collection as otherwise this “one third” rule is difficult
to adhere to.
In order to achieve an optimal mulching result, you should reduce the speed of the
machine when mulching compared to traditional mowing, to give the grass time to stay
longer in the mower and to be thus cut several times.
The best cut pattern and result is achieved on a dry lawn, as wet lawn quickly sticks and
clumps due to the short grass sections. These lumps of grass rot and get mouldy and
hinder the desired ecological cycle.
