Maintenance And Repairs - Viking LB 540 Instruction Manual

Risk of injury through defective
parts!
Strong vibration is normally an
indication of a fault.
In particular, the machine must not
be operated with a damaged or
bent scarifying unit (blade shaft,
blades, spacer bushings and
fastening).
In the event of excessive vibration or after
a collision with an obstacle, check the
machine, in particular the scarifying unit
(blade shaft, blades, spacer bushings and
fastening), the housing and the discharge
flap for damage and loose parts and carry
out the necessary repairs before re-
starting and working with the machine. If
you do not have the appropriate expertise,
have the necessary repairs carried out by
a specialist dealer (VIKING recommends
VIKING specialist dealers).

4.7 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.

Risk of injury!
Pulling the recoil starter rope starts
the blades rotating. Always ensure
sufficient distance between the
blades 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. (
Remove accumulated clipping deposits
using a stick. Clean the underside of the
machine 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.
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
11.2)
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.
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.
Wear thick work gloves and exercise
extreme care when performing work on the
scarifying unit.
For safety reasons, fuel-carrying
components (fuel line, fuel cock, fuel tank,
tank cap, connections, etc.) must be
checked regularly for damage and leaks
