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.

11. Blade brake clutch (BBC)

Models MB 650 VS, MB 655 RS,
MB 655 VS, MB 655 YS are
equipped with a blade brake clutch
(BBC).
Risk of injury!
Operation of the blade brake clutch
must be checked before each use.

never be disabled, e.g. by tying it to
the handlebar.

while the engine continues to run. (
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.
