0. Notes on working with
the machine
A perfect, thick lawn is achieved by
– Mowing at low driving speeds.
– Mowing regularly and keeping the grass
short.
– Not cutting the lawn too short in hot, dry
conditions as it will be burnt by the sun
and become unsightly.
– Using a sharp mowing blade – mowing
blade should therefore be sharpened
regularly (specialist dealer).
– Changing the cutting direction regularly.

. Initial operation of the
machine

. Starting the engine

Avoid damage to the machine.
Do not start the engine in tall grass
or at the lowest cutting height. This
makes starting difficult.
Thanks to the fixed throttle setting,
the engine always operates at the
optimum working speed after
starting.
Start procedure when the engine is
cold.
