10.2 Motorstop lever

Models MB 650 T, MB 650 V, MB
650 VE, MB 655 V are equipped
with a motorstop device.
The engine stops when motorstop
lever (1) is released during running
operation.
The engine and blade come to a standstill
within 3 seconds.
Risk of injury!
If the run-on time of the blade
exceeds this delay, stop using the
machine and take it to your
specialist dealer.
Measuring the run-on time
Following engine start-up, the blade
rotates and a wind noise is audible. The
run-on time corresponds to the duration of
the wind noise after the engine stops. This
can be measured using a stopwatch.

Models MB 650 VS, MB 655 RS,
MB 655 VS, MB 655 YS are
equipped with a blade brake clutch
(BBC).

must be checked before each use.

12. 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.
