4.8 Maintenance and repairs

Before beginning cleaning,
adjustment, repair and
maintenance operations, park
the machine on firm, level ground, engage
the parking brake, stop the engine, allow it
to cool down and remove the ignition key.
Allow the machine to cool down before
working on or around the engine, exhaust
manifold or muffler; this also applies in
particular to all maintenance operations on
the mowing deck. Temperatures of 80° C
and above can be reached. Danger of
burns:
Cleaning:
Following operation, the entire ride-on
mower and the attachments must be
cleaned. In particular, all grass residues
must be removed because the moisture
these contain leads to damage in the long
term.
VIKING does not recommend the use of
high pressure cleaners. ( 13.19)
Never drive close to an edge or a ditch for
the purpose of cleaning (e.g. the frame of)
the ride-on mower.
In order to prevent fire hazards, keep the
engine, cooling ribs, battery compartment,
area around the fuel tank and exhaust free
from grass, leaves or escaping oil (or
grease).
Always clean the grass catcher box.
Maintenance operations:
Only maintenance operations described in
this instruction manual may be carried out.
Have all other work performed by a
specialist dealer.

If you do not have the necessary expertise
or auxiliary equipment, please always
contact a specialist dealer.
VIKING recommends that you have
maintenance operations and repairs
performed exclusively by a VIKING
specialist dealer.
VIKING specialist dealers regularly attend
training courses and are provided with
technical information.
Only use tools, accessories or
attachments approved for this machine by
VIKING or technically identical parts.
Otherwise, there may be a risk of
accidents resulting in personal injury or
damage to the machine. If you have any
questions, please consult a specialist
dealer.
The characteristics of original VIKING
tools, accessories and spare parts are
optimally adapted to the machine and the
user's requirements. Genuine VIKING
spare parts can be recognised by the
VIKING spare parts number, by the
VIKING lettering and, if present, by the
VIKING spare parts symbol. On smaller
parts, only the symbol may be present.
The ride-on mower and all attachments
should be inspected once annually by a
specialist dealer. ( 13.1)
Always keep warning and information
stickers clean and readable. Damaged or
missing stickers must be replaced by new,
original plates from your VIKING specialist
dealer. If a component is replaced with a
new component, ensure that the new
component is provided with the same
stickers.
For safety reasons, fuel-carrying
components (fuel line, fuel cock, fuel tank,
tank cap, connections, etc.) must be
checked regularly for damage and leaks
and replaced by a technician if necessary
(VIKING recommends VIKING specialist
dealers).
Before starting work on or near electrical
components, the negative (–) cable must
be disconnected from the battery.
The machine is equipped with numerous
safety devices. These devices must not be
removed or modified (bypassed, etc.) and
must be checked at regular intervals.
Operations on the safety devices must
only be carried out by a technician.
VIKING recommends VIKING specialist
dealers.
Ensure that all nuts, pins and screws,
especially the blade fastening screw, are
securely tightened, so that the machine is
in a safe operating condition.
For safety reasons, worn or damaged
parts must be replaced immediately.
Check the grass catcher unit (e.g. grass
catcher box, discharge chute) regularly for
wear, damage or loss of functionality.
Particular care is required when working
under the machine, due to the weight of
the ride-on mower. If necessary, contact a
specialist dealer; VIKING recommends
VIKING specialist dealers. They will have
a workshop pit or a hydraulic working
platform.
Check the secure fastening of the front
and rear wheels.
Always maintain the ride-on mower and
the attachments in perfect operating
condition. All safety devices must be
present and be in perfect operating
condition.
Ensure that the tyres have the correct tyre
pressures. The tyre pressures specified in
the instruction manual must not be
exceeded.
