Working Area For Operator; Operating The Machine; Starting The Engine; Stopping The Engine - Viking MB 253 T Gebrauchsanleitung

Measuring the run-on time
Following engine start-up, the blade

run-on time corresponds to the duration of
the wind noise after the engine stops. This

9. 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.
