How is the perfect grass blade cut achieved?
The length of the grass to be cut should not exceed 10 cm when a mulching mower is
used. A maximum of 1/3 of the grass height is cut in one working cycle. If a positive
result is not achieved, mulching may have to be repeated.
Depending on the type of lawn and growth intensity, the grass should be mowed
regularly. During the strong growing phase in particular, mulch-mowing needs to be
done more frequently than traditional mowing with grass collection, since the one-third
rule is hard to keep otherwise.
To achieve an optimum mulching result you should reduce the machine speed for
mulching compared to traditional mowing to allow the grass to remain in the mowing
blade longer and thus be cut several times.
The best cutting pattern and result are achieved on a dry lawn, since wet cut grass will
stick together and clump quickly. These grass clumps will rot and mould, preventing the
desired ecological cycle.
If the lawn has to be mowed in a very damp, wet state, the cut grass must be shorter
i.e. the cutting height must be set 1-2 levels higher than with a dry lawn.
You will notice that if you follow these simple rules you will have a healthy lawn and can
save on disposing of your grass cuttings.
15 SERVICE INTERVALS
IMPORTANT
Avoid damage! Under extreme or unusual conditions, shorter servicing intervals
than the ones specified below may be necessary. If you establish any problems,
please contact an authorised workshop.
Carry out routine servicing on the machine in line with the following servicing intervals.
Work must be carried out at the following servicing intervals in addition to the
maintenance work listed in these operating instructions.
Before initial use

16 CARE AND SERVICING OF YOUR LAWNMOWER
Regular care is the best way to guarantee a long service life and problem-free
operation. Insufficient equipment maintenance will lead to safety-related faults!
Only use original spare parts because only those guarantee safety and quality!
Cleaning (Illustration A + O )
IMPORTANT
During cleaning and maintenance work, close the fuel tap A (SA322020), tilt the
mower forwards O (spark plug facing upwards). If it should become necessary
to place the mower on its side, then place it on the exhaust side, never on the
carburettor side, as otherwise start-up problems could occur. Secure the mower
in its raised position!
NOTE
When tilting the mower upwards or placing it on its side, make sure no oil or
petrol escapes. Fire hazard!
Remove dirt and residual grass directly after mowing. Use a brush or cloth for cleaning.
Do not rotate the cutter bar, as otherwise motor oil is pumped into the carburettor/air
filter and start-up difficulties can occur.
IMPORTANT
Never use high-pressure cleaners or a normal water jet to clean the drive area,
engine parts (such as ignition system, carburettor etc.), seals and bearing points.
Damage or expensive repairs can be the consequence of such action.
Storage
Always keep the machine in a clean condition in a closed, dry room out of reach of
children. Always allow the engine to cool down before you store the machine in a
closed room.
Collapsing the handle (Illustration B4 )
IMPORTANT
Make sure that the cables are not pinched, squeezed, twisted or overstretched
when the handlebars are folded apart or collapsed! Always run the cables along
the outside of the bar connection. A damaged cable may result in a technical
defect of the equipment.
–
To save storage space or for transport, loosen the two handle nuts such that the
top guide tube can be folded down towards the engine.
–
Do not kink nor squeeze the throttle cables in the process.
CAUTION
When folding the bar for transport and storage, the bar may fold over
unintentionally when the grip nuts are released. In addition, beware of potential
crushing spots between the bottom and top parts of the bar. This may result in
risk of injury!
Transporting and securing the equipment (Illustration N + N4 )
–
In case the equipment has to be carried, hold it by the carrying handle at the front
(1) and on the cross tube of the top part of the handlebar (2) at the back or by the
cross tube of the bottom part of the handlebar if this is folded (3)
(see illustration N ).
Please take the weight of the machine into consideration before lifting it (see
Technical Data). Lifting large weights can result in health problems.
We recommend that this equipment should always be lifted or carried by at least
two people, when other means of help are not at disposal.
When this equipment is transported on a load area, a loading ramp should be used
for loading and unloading.
NOTE
Avoid injuries! Be especially careful when loading or unloading the equipment.
When a trailer is used, we recommend ensuring that it is equipped with stable
sidewalls.
