danger of suffocation! Keep
packaging material away from
children.
Danger to life!
Petrol is poisonous and extremely
inflammable.

Page: 4

0478 111 9922 B — EN
30
Petrol must only be stored in appropriate,
tested containers (canisters). Always
screw on the fuel tank and canister caps
properly and tightly. Defective caps must
be replaced for safety reasons.
Never use beverage bottles or similar for
disposal or storage of fuels and lubricants.
Persons, particularly children, could be
tempted to drink out of them.
Keep petrol away from sparks,
naked flames, pilot lights, heat
sources, and other ignition
sources. Do not smoke!
Refill the tank out-of-doors and do not
smoke during refilling.
Before refilling the tank, stop the engine
and allow it to cool.
Refilling with petrol must be performed
before the engine is started. When the
engine is running or is hot, the tank cap
must not be removed and the tank must
not be refilled with petrol.
Do not fill the fuel tank completely, but fill
to approx. 4 cm below the edge of the filler
neck so that the fuel has room to expand.
If petrol is spilled, the engine must only be
started after the petrol-contaminated area
has been cleaned. All attempts at starting
must be avoided until the petrol fumes
have dispersed (wipe dry).
Any spilt fuel must be wiped up
immediately.
Clothing must be changed if it comes into
contact with petrol.
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 it is necessary to drain the tank, this must
be done out of doors.
4.3 Clothing and equipment
Always wear sturdy footwear
with high-grip soles when
working. Never work barefoot
or, for example, in sandals.
Also always wear sturdy gloves
and tie up and secure long hair
(headscarf, cap, etc.) when
performing maintenance and
cleaning work or when transporting the
machine.
Wear suitable safety glasses
when sharpening the mowing
blade.
Always wear long trousers and
tight-fitting clothing when operating the
machine.
Never wear loose clothes which may
become caught on moving parts (control
levers) – do not wear jewellery, ties or
scarves.
4.4 Transporting the machine
Always wear gloves in order to prevent
injuries due to sharp-edged and hot
components.
Do not transport the machine with the
engine running. Switch off the engine, let
the blades come to a standstill and remove
the spark plug socket prior to transport.
Only transport the machine once the
engine has cooled down and with an
empty fuel tank.
Use suitable loading aids (loading ramps,
lifters).
Secure the machine and any machine
components being transported (e.g. grass
catcher box) on the load floor using
fastening material of adequate size (belts,
ropes, etc.).
Avoid contact with the mowing blade when
lifting and carrying the machine.
Observe the information in the section
«Transport». It describes how to lift and
lash the machine. (Ö 12.)
When transporting the machine, always
observe regional legislation, especially
regarding load security and the transport
of objects on load floors.
4.5 Before operation
Make sure that only persons who are
familiar with the instruction manual are
permitted to use the machine.
Check the fuel system (particularly visible
parts such as e.g. tank, tank cap, hose
connections) before operating the
machine. In the event of any leaks or
damage, do not start the engine – fire
hazard!
Have the machine repaired by a specialist
dealer prior to operation.
Observe the local regulations regarding
permitted operating times for gardening
power tools with combustion engines or
electric motors.
Carefully inspect the complete area on

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
supply of replacement stickers and all the
other spare parts.
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. (Ö 11.5)
– 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,
handlebar, protective grille) are in good
condition and working properly.
– The grass catcher box is undamaged
and correctly installed; a damaged
grass catcher box must not be used.
– The oil closure screw is properly
attached.
Carry out any necessary work or consult a
specialist dealer. VIKING recommends
VIKING specialist dealers.
4.6 Working with your machine
Never work when animals or
persons, particularly children,
are in the danger area.
The switch and safety devices installed in
the machine must not be removed or
bypassed. In particular, never secure the
motorstop lever to the handlebar (e.g. by
tying it).
Caution – risk of injury!
Never put hands or feet on or
underneath rotating parts.
Never touch the rotating blade.
Always keep away from the discharge
opening.
Always observe the safety distance
provided by the handlebar. The handlebar
must always be installed correctly and
must not be modified. Never operate the
machine with the handlebar folded down.
Never attach any objects to the handlebar
(e.g. work clothing).
Only work during the day or with good
artificial light.
Do not operate the machine in the rain or
during thunder storms, particularly when
there is a risk of lightning strike.
The risk of accidents is higher if the ground
is damp due to increased danger of
slipping.
Particular caution should be exercised
during working in order to prevent slipping.
If possible, avoid using the machine when
the ground is damp.
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 and observe
the instructions contained in the section
entitled «Initial operation of machine».
(Ö 10.)
Keep your feet a safe distance from the
cutting tool.
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.
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.

Page: 6

0478 111 9922 B — EN
32
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 rubbish dumps, 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,
– 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.
– Before opening the discharge flap or
removing the grass catcher box.
– When the machine has to be tilted for
transportation.
– Before adjusting the cutting height.
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!
Never place your hands or feet
above, underneath or on rotating
parts.
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).

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. (Ö 11.2)
Remove accumulated clipping deposits
using a stick. Clean the underside of the
mower with water and a brush.
Empty the fuel tank (e.g. by running it
empty) before placing the machine in the
cleaning position.
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
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).
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.

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!

7.8 Fuel and engine oil
Engine oil:
Please consult the engine
instruction manual for the type of
engine oil to be used and the oil capacity.
Check the oil filling level at regular
intervals (see engine instruction manual).
Avoid exceeding or falling below the
correct oil level.
Fuel:
Recommendation:
Fresh good quality fuel.
Please consult the engine
instruction manual for details on the fuel
quality (octane rating).
– Unleaded petrol
A funnel should be used when filling the
tank with fuel (not included in standard
equipment).
The machine is equipped with several
safety devices for safe operation and for
the prevention of improper use.
8.1 Safety devices
The lawn mower is equipped with safety
devices, which prevent inadvertent contact
with the mowing blade and with ejected
clippings.
These include the housing, discharge flap,
grass catcher box and correctly-installed
handlebar.
8.2 Motorstop lever
The lawn mower is equipped with a
motorstop device.
The engine stops when the motorstop
lever is released during running operation.
The engine and blade come to a standstill
within 3 seconds.
Measuring the run-on time
Following engine start-up, the blade
rotates and a wind noise is audible. The
run-on time corresponds to the duration of
the wind noise after the engine stops. This
can be measured using a stopwatch.
A perfect, thick lawn is achieved by
– Mowing at low driving speeds.
– Mowing regularly and keeping the grass
short.
– Not cutting the lawn too short in hot, dry
conditions as it will be burnt by the sun
and become unsightly.
– Using a sharp mowing blade – mowing
blade should therefore be sharpened
regularly (specialist dealer).
– Changing the cutting direction regularly.
Risk of injury!
Stop the engine before adjusting
the cutting height.
Risk of injury!
Note the warnings in the section
«For your safety». (Ö 4.)
Avoid damage to the machine.
Top up the engine oil before starting
for the first time (see engine
instruction manual). VIKING
recommends using a suitable filling
aid when topping up the engine oil
(e.g. funnel). The filling aid is not
included in the standard equipment.
7

8. Safety devices
Risk of injury
If a safety device is found to be
defective, the machine must not be
operated. Consult a specialist
dealer; VIKING recommends
VIKING specialist dealers.
Risk of injury!
If the run-on time of the blade
exceeds this delay, stop using the
machine and take it to your
specialist dealer.

11.1 General
Annual service by the specialist dealer:
The lawn mower should be inspected once
annually by a specialist dealer. VIKING
recommends VIKING specialist dealers.
11.2 Cleaning the machine
Maintenance interval:
After each use
10. Operating the machine
Avoid damage to the machine.
Do not start the engine in tall grass
or at the lowest cutting height. This
makes starting difficult.
Thanks to the fixed throttle setting,
the engine always operates at the
optimum working speed after
starting.
Avoid damage to the machine.

Mowing blade thickness:
The blade thickness (A) must be at least
2 mm at any point. The most important
points are marked in the illustration.
(Check using slide calliper).
Wear limit of the cutting edges:
The cutting edges must not be ground
back by more than 5 mm (distance (B))
during sharpening. When checking, place
a ruler (2) against the front blade edge (3)
and check for wear.
11.5 Maintaining the mowing
blade
Removing the mowing blade:

● Loosen and unscrew the blade
fastening screw (3). Remove the blade
fastening screw (3), washer (4) and
mowing blade (2).
Sharpening the mowing blade:
● Cool the mowing blade when
sharpening, e.g. with water. The blade
must not be allowed to display blue
colouring, as this would reduce its
cutting quality.
● Sharpen blades evenly to prevent
vibration due to imbalance.
● The cutting angle of 30° must be
observed.
Risk of injury!
Stop the engine and remove the
spark plug socket.
Empty the fuel tank (run empty)
before placing the machine in the
cleaning position.
Risk of injury!
Observe the safety instructions in
the «For your safety» section. (Ö 4.)
Risk of injury!
A worn mowing blade may break
off and cause serious injuries. The
instructions for blade maintenance
must therefore always be
observed.
Mowing blades are subject to
differing degrees of wear
depending on the location and
duration of use. If you use the
machine on sandy ground or use it
frequently under dry conditions, the
mowing blade will be subjected to
greater loads and will wear more
quickly than the average.
14
Risk of injury!
Observe the safety instructions in
the section «For your safety». (Ö 4.)
We recommend that you have the
mowing blade sharpened by a
specialist dealer.
Risk of injury!
Always wear safety glasses and
