Information on mowing
Prior to mowing, check the device for com-
pleteness, proper function, and cleanliness. A
dirty ventilation grid causes overheating of the
engine which can result in engine damage.
For your grass to grow beautiful and thick,
mow frequently and keep the grass short. Do
not mow your lawn too low in dry and hot con-
ditions because the lawn is susceptible to sun
and heat damage and will look unsightly!
Only mow with a sharp and undamaged blade
so that the blades of grass do not fray. Have
the blade sharpened and balanced regularly
(authorised service centre).
Do not mow when the grass is wet or when it is
raining. The turf may be damaged and there is
a danger of slipping!
Turn the device around only in already mown
sections. Do not leave the device unattended
while the engine is running.
To evenly distribute grass remains and to
achieve an even cutting height, we recom-
mend, for flat terrain, to proceed according to
the illustrated mowing pattern.
A mulching mower shreds the clippings better
and finer than a conventional mowers. For an
optimal cutting pattern, please heed the follow-
ing recommendations.
Recommendations for mowing with
mulching mowers:
– Mow only 1/3 of the grass height.
– Do not set the brush height to the lowest po-
sition. Recommendation: 50-60mm.
– Work under dry conditions.
– Start with slow speed.
– The slower you drive the better the cutting
result.
– If the grass is too high, you should mow in
maximum cutting height first and later mow
again in the recommended cutting height.
– If clumps form or the mulching layer is too
thick, the air exchange of the soil can be re-
stricted. Areas of rot can result.

16
Prior to starting
Charging the battery
