VIKING specialist dealers).

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.
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.
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.

Only maintenance operations described in
this instruction manual may be carried out.
Have all other work performed by a

or auxiliary equipment, please always
