8. Blade brake clutch (BBC)

10
Your lawn mower is equipped with a
blade brake clutch (BBC).
This means that the mowing blade stops
within a short time after it is disengaged,
but the engine keeps running.
In order to prevent injuries or damage to
the machine, ensure that you are familiar
with operation of the BBC system prior to
initial use.
Two-hand operation:
The mowing blade can only be engaged as
follows with the engine running:
Press blade stop lever (1) towards the
handlebar and hold, then pull blade clutch
lever (2) upwards with the other hand and
allow it to engage.
Risk of injury!
11
For safety reasons, the lever must
never be disabled, e.g. by tying it to
the handlebar.
Operation of the blade brake clutch
must be checked before each use.
( 10.4)
Avoid damage to the machine!
Avoid overloading as this can result
in greater wear to the blade brake
clutch and consequently to
overheating. (
9. Notes on working with the
machine
Avoid overloading of the blade brake
clutch
An overload can occur
– if mowing is continued when the grass
catcher bag is full.
– if the mowing channel is blocked.
– if mowing at excessive speed in high
grass.
14
If the mowing blade is blocked, the grass is
no longer cut and the engine cuts out.
For this reason, never mow when the
mowing channel is blocked or the grass
catcher bag is full; adapt the driving speed
to the conditions. Use a mulching kit
(special accessory) if necessary.
