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).

5.8 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 650 VE: Additionally remove the
battery.
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!
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.
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.
Cleaning:
The complete machine must be cleaned
thoroughly following use. (
Empty the fuel tank (e.g. by running it
empty) before placing the machine in the
cleaning position.
Remove accumulated clipping deposits
using a stick. Clean the underside of the
mower with water and a brush.
Never use high-pressure cleaners and do
not clean the machine under running water
(e.g. using a garden hose).
Do not use aggressive cleaning agents.
These can damage plastics and metals,
impairing the safe operation of your
VIKING machine.
In order to prevent fire hazards, keep the
area around the air vents, cooling ribs and
the area of the exhaust free from
e.g. grass, straw, moss, leaves or
escaping grease.
