Maintenance And Repairs - Viking MB 4 R Gebrauchsanleitung

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 try to examine the blade
while the lawn mower is
operating. 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.
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 grass (lawn sprinkler
systems, posts, water valves, foundations,
electrical wires, etc.) must be avoided.
Never intentionally run over any such
foreign objects.
Beware of the cutting tool
running on for several seconds
before coming to a standstill.
Switch off 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 filling the
tank.
Fire hazard!
– before remedying blockages, including
those in the mowing deck housing,
– 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 blade shaft 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.
– When the machine has to be tilted for
transportation.
– Before adjusting the cutting height.

4.7 Maintenance and repairs

Before beginning cleaning,
adjustment, repair and
maintenance operations, park
the machine on firm, level
ground, stop the engine, allow it to cool
down and detach the spark plug socket.
Risk of injury due to the mowing
blade!
Pulling the recoil starter rope starts
the work tool rotating. Always
ensure sufficient distance between
the mowing blade and your body,
particularly your hands and feet,
when you pull the recoil starter
rope.
