Maintenance And Repairs - Viking MB 248 Manuel D'utilisation

Always ensure good stability on slopes
and avoid mowing on excessively steep
slopes.
For safety reasons, the machine must not
be used on slopes with an inclination of
more than 25° (46.6%). Risk of injury!
A slope inclination of 25° corresponds to a
vertical height increase of 46.6 cm for a
100 cm horizontal distance.
In order to ensure an adequate oil supply
for the engine, the information in the
accompanying engine instruction manual
must be additionally observed when using
the machine on slopes.
Working:
Risk of injury!
Never place your hands or feet
above, underneath or on rotating
parts.
Do not attempt to examine the
blade while the lawn mower is
operating. Never open the
discharge flap and/or remove the grass
catcher box when the mowing blade is
running. Rotating blades can cause injury.
Only operate the machine at walking
speed – never run when working with the
machine. Working quickly with the
machine increases the risk of injury due to
stumbling, slipping, etc.
32
Be particularly careful when turning the
machine around or pulling it towards you.
Risk of stumbling!
Use the machine with great care when
working near rubbish dumps, ditches and
embankments. In particular, ensure that
you maintain sufficient distance to such
danger areas.
Objects hidden in the turf (lawn sprinkler
systems, posts, water valves, foundations,
electrical wires, etc.) must be avoided.
Never run over any such foreign objects.
Beware of the cutting tool
running on for several seconds
before coming to a standstill.
Stop the engine, allow the work
tool to come to a complete
standstill and detach the spark plug socket
– before leaving the machine unattended,
– before re-filling the tank. Allow the
engine to cool down before re-filling the
tank.
Fire hazard!
– before remedying blockages, including
those in the discharge chute,
– before lifting or carrying the machine,
– before transporting the machine,
– before carrying out any work on the
mowing blade,
– before checking or cleaning the
machine or before carrying out any
other work (e.g. folding down the
handlebar) on it,
– after hitting a foreign object or if the
lawn mower begins to vibrate
excessively. In these cases check the
machine, in particular the cutting unit
(blade, blade shaft, blade fastening) for
damage and carry out the necessary
repairs before restarting and working
with the machine.
Risk of injury!
Strong vibrations are generally an
indication of a fault.
In particular, the lawn mower must
not be operated with a damaged or
bent crankshaft or mowing blade.
If you do not have the appropriate
expertise, have the necessary
repairs carried out by a specialist
dealer (VIKING recommends
VIKING specialist dealers).
Switch off the engine
– When pushing the machine to and from
the area to be worked.
– Before pushing the machine onto an
area not covered with grass.
– Before opening the discharge flap or
removing the grass catcher box.
– When the machine has to be tilted for
transportation.
– Before adjusting the cutting height.
