Checking the blade brake clutch
Operation of the blade brake clutch must
be checked
three times
before starting
work.
●
Engage the mowing blade with the
engine running. (
A running mowing blade generates a
clearly audible wind noise.
●
Disengage the mowing blade (release
the handlebar). (
The blade brake clutch disengages the
mowing blade from the engine drive
and brakes it. This procedure is
accompanied by stopping of the wind
noise and lasts a maximum of 3
seconds. No wind noise must be
audible when the blade is stopped. The
blade brake time can be measured
using a stopwatch.

3. Operating the machine
Risk of injury!
Should the blade brake clutch not
work as described (e.g. longer
blade brake time than 3 seconds or
continuing audible wind noise when
the mowing blade is disengaged),
the machine must not be operated.
In this case, switch off the engine,
detach the spark plug socket and
have the necessary repairs
performed by a qualified technician.
VIKING recommends VIKING
specialist dealers.
Avoid damage to the machine!
Do not start the engine in tall grass.
Select a higher cutting height
setting if the engine is difficult to
start.
Thanks to the fixed throttle setting,
the engine always operates at the
optimum working speed after
starting.
