Maintenance And Repairs - Viking MB 545 Manual Del Usuario

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.
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 slopes, terraces, 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.
Switch off the engine, allow the
work tool to come to a complete
standstill, detach the spark plug socket
and additionally remove the battery (with
MB 545 VE),
– 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 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 vibration is normally 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).
Stop 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.

4.8 Maintenance and repairs

Before beginning cleaning, adjustment,
repair and maintenance operations:
● Park the machine on firm and level
ground
● Stop the engine and allow it to cool
down
● Detach the spark plug
socket.
Caution – risk of injury!
Keep the spark plug socket
away from the spark plug; an inadvertent
ignition spark can result in fires or electric
shocks.
Inadvertent contact between the spark
plug and the spark plug socket can result
in unwanted starting of the engine.
MB 545 VE: Additionally remove the
battery.
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.
Allow the machine to cool down before
working on or around the engine, exhaust
manifold or muffler in particular.
Temperatures of 80° C and above can be
reached. Danger of burns!
Direct contact with engine oil can be
dangerous. Engine oil must not be spilled.
VIKING recommends leaving the task of
topping up engine oil or performing engine
oil changes to a VIKING specialist dealer.
