permitted operating times for gardening
power tools with combustion engines or
electric motors.
Carefully inspect the complete area on
which the machine is to be used and
remove any stones, sticks, wires, bones
and other foreign objects which could be
thrown up by the machine. Obstacles (e.g.
tree stumps, roots) can be easily
overlooked in long grass.
For this reason, mark all foreign objects
(obstacles) which are hidden in the lawn
and cannot be removed before
commencing work with the machine.
Defective and all other worn or damaged
parts must be removed before using the
machine. Replace any illegible or
damaged danger signs and warnings on
the machine. Your VIKING specialist has a

socket on the spark plug before using the
machine.
The machine must only be used in good
operating condition. Before each use,
check whether:
– The machine is properly assembled.
– The cutting tool and the entire cutting
unit (mowing blade, fastening
attachments, mowing deck housing)
are in good condition. In particular
check for secure fastening, damage
(notches or cracks) and wear. (Ö12.4)
– The tank cap is properly attached.
– The tank and fuel-carrying parts as well
as the tank cap are in good condition.
– The safety devices (e.g. motorstop
lever, discharge flap, housing,

If possible, avoid using the machine when
the ground is damp.

0478 111 9823 F - EN
16
Exhaust gases:
The machine generates
poisonous exhaust gases when
the engine is running. The
gases contain poisonous
carbon monoxide, a colourless and
odourless gas, as well as other pollutants.
The engine must never be operated in
closed or poorly ventilated spaces.
Starting:
Exercise care when starting the machine
and observe the instructions contained in
the section entitled "Operating the
machine" (Ö11.). Starting the machine in
accordance with these instructions
reduces the risk of injury.
Risk of injury!
If the starter rope recoils at speed, the
hand and arm will be pulled towards the
engine faster than the starter rope can be
released. This kickback can result in
broken bones, crush injuries and sprains.
Keep your feet a safe distance from the
cutting tool when starting the machine.
The machine must not be tilted during
start-up.
The self-propulsion lever must not be
pressed when starting the engine.
Do not start the engine if the discharge
chute is not covered by the discharge flap
or the grass catcher box.
Working on slopes:
Always work across and back on slopes,
never up and down.
If the user loses control when mowing up
and down, there is a risk of being run over
by the machine.
Be particularly careful when changing
direction on a slope.
Always ensure good stability on slopes
and avoid mowing on excessively steep
slopes.
For safety reasons, the machine must not
be used on slopes with an inclination of
more than 25° (46.6%). Risk of injury!
A slope inclination of 25° corresponds to a
vertical height increase of 46.6 cm for a
100 cm horizontal distance.
In order to ensure an adequate oil supply
for the engine, the information in the
accompanying engine instruction manual
must be additionally observed when using
the machine on slopes.
Working:
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.
Stop the engine, allow the work
tool to come to a complete
standstill and detach the spark plug socket
– before leaving the machine unattended,
– before re-filling the tank. Allow the
engine to cool down before re-filling the
tank.
Fire hazard!
– before remedying blockages, including
those in the discharge chute,
– before lifting or carrying the machine,
– before transporting the machine,
Danger to life through poisoning!
In the case of nausea, headache,
impaired vision (e.g. decreasing
field of view) hearing disorder,
dizziness, decreasing power of
concentration, stop working
immediately. These symptoms may
be caused by excessively high
exhaust gas concentrations.
Risk of injury!
Never place your hands or feet
above, underneath or on rotating
parts.

ENSK

0478 111 9823 F - EN
– 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.
Switch off 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.

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.
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. (Ö12.3)
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.
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.
Risk of injury!
Strong vibrations are generally 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).
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.

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.
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).
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.
Only perform work on the cutting unit when
wearing thick work gloves and exercising
extreme care.
Ensure that all nuts, pins and screws (in
particular the blade fastening screw) are
securely tightened so that the machine is
in a safe operating condition.
Check the complete machine and the
grass catcher box for wear or damage on
a regular basis, particularly before
extended periods when the machine is not
in use (e.g. over winter). For safety
reasons, worn or damaged parts must be
replaced immediately to ensure that the
machine is always in a safe operating
condition.
Never alter the basic setting of the engine
or run at excessive engine speeds.
Components or guards that are removed
for maintenance operations must be
properly reinstalled immediately.
4.8 Storage for prolonged periods
without operation
Allow the engine to cool before storing the
machine in an enclosed space.
Store the machine with empty fuel tank
and the fuel reserve in a lockable and well-
ventilated room.
Ensure that the machine is protected from
unauthorised use (e.g. by children).
Never store the machine with petrol in the
tank inside a building. The resulting petrol
fumes could come into contact with naked
flames or sparks and could be ignited.
If the tank has to be emptied (e.g. to store
the machine before the winter break), this
should only be done out of doors (e.g. by
running the tank empty).
Thoroughly clean the machine before
storage (e.g. winter break).
Only store the machine with the spark plug
socket disconnected.
Store the machine in good operational
condition.
Allow the machine to cool down
completely before covering it.
4.9 Disposal
Waste products such as used engine oil or
fuel, used lubricants, filters, batteries and
similar wearing parts can be harmful to
people, animals and the environment, and
must consequently be disposed of
properly.
Consult your recycling centre or your
specialist dealer for information on the
proper disposal of waste products. VIKING
recommends VIKING specialist dealers.
Ensure that old machines are properly
disposed of. Render the machine
unusable prior to disposal. In order to
prevent accidents, remove the ignition
lead, empty the fuel tank and drain the
engine oil in particular.
Risk of injury due to the mowing blade!
Always store an old lawn mower in a safe
place prior to scrapping. Ensure that the
machine and particularly the mowing blade
are kept out of the reach of children.
