ASSEMBLING
EJECTION SHIELD
Undernoconditionmustthe machinebe
startedwithouttheejectionshieldbeing
fitted on the machine. If it is not fitted,
stones and other flying objects may easily be ejected by the rotating bla de.
Fit the ejection shield in the holes on the chassis
with the help of two nuts. Tighten the nuts fully
(fig. 1).
HANDLEBAR
Move the upper part of the steering handle upwards and tighten the locking knobs (fig. 2). The
height of the handle can be adjusted in three different positions.
USING THE MOWER
BEFORE STARTING
FILL THE CRANKCASE WITH OIL
The lawn moweris deliveredwithoutany
oil in the motor crankcase. The crankcase must, therefore, be filled with oil before the motor is started the first time.
Remove the oil dipstick (fig. 3,4). Fill the engine's
crankcase with 0.6 litres of good quality oil (service class SE, SF or SG) Use SAE 30 or SAE 10W30 oil.
Fill until the oil reaches the “FULL/MAX” mark
on the dip stick. Do not fill with too much oil.
CHECKING THE OIL LEVEL
Check before using the machine that the oil level is
between “FULL/MAX” and “ADD/MIN” on the
dipstick.
Remove and dry the d ipstick (fig. 3,4). Slide it
down completely and tighten it. Unscrew and pull
itup again.Read-off.If the o il levelislow,fill with
oil up to the “FULL/MAX” mark.
FILL UP THE PETROL TANK
Fill with petrol before starting the motor. Never remove the fillercap or fill
with petrol while the motor is runni ng
or still warm.
Never fillthe fuel tank completelyfull but allowa
little room for the petrol to expand.
Always use pure unleaded petrol. You must never
use 2-stroke petrol mixed with oil.
Note that you should always remember that petrol
is a perishable commodity .Never buy more petrol
than what you can use up in 30 days.
STARTING THE ENGINE
Keephands and feetwell awayfrom the
rotating blade. Never put your hand or
foot under the blade casing or in the
grass evacuation unit while the motor is
running.
1. Place the lawn mower on flat, firm ground. Do
not start in high grass.
2. Make sure the spark plug lead is connected to
the spark plug.

3. When starting a cold engine: Press down the
primer fully 6 times (fig. 5,6).
When starting a warm engine the primer does
not need to be used. If the engine stops due toa
lack of petrol, refill and press down the primer
3 times.
4. Press in the Start/Stop-loop H against the steering. Note that the Start/Stop loop H must be
kept pressed-in to prevent the engine from stopping (fig. 7).
5a Manual starting: Grasp the starter handle and
start the engine by pulling briskly on the starter
handle.
5b Electric starting facility (*): Start the engine by
turning the starter key clock-wise. Release the
key as soon as the engine starts. Alw ays make
short attempts at starting to prevent discharging
the battery.
IN/ OUT COUPLING OF THE DRIVE
CUTTING HEIGHT
Shut off the motor before adjusting the
cutting height.
Do not set the cutting height so low that
the blade can h it uneven ground.
Avoid mowing when the grass is wet. The grass
then sticks to the underside of the casing, giving
poor mowing results.
Themowerisfittedwithasinglelevercontrolfor
adjusting the cutting height. Pull the lever outwards and adjust the cutting height on one of the 8
positions to be most suitable for your lawn (fig. 8).
MAINTENANCE

By pressing down the handlebar so thatthe driving
wheels release their grip on the ground, turning, reversing, moving round trees etc. can be done without having to disengage the drive system.
STOP OF ENGINE
Themotormaybeverywarmimmediately after it is shut off. Do not touch the
silencer, cylinder or cooling flanges as it
can cause burns and injury.
1. Release Start/Stop-loop H to stop the engine
(fig. 7). This loop must not be disengaged (e.g.
through fixing it in the depressed position
against the steering), as the engine cannot be
stopped.
2. If the lawn mower is left unattended to, remove
the lead from the spark plug.
Tornado51SE:Remove the starter key.
If the start/stop loop no longer works,
stop the engine by removing the lead
from the spark plug. Immediately take
the lawn mower to an authorised workshop for repairs.
Stop the motor and remove the spark
plug cable if the mower is to be lifted,
e.g. with transportation.
Ifthe machineis to betilted thefuel tank
must be emptied and the sparking plug
of the engine kept upwards.
CLEANING
After each time it is used the mower should be
cleaned. This is particularly important on the underside of the mower casing. Wash out with the
garden hose. The mower will then last longer and
function better.
Note! High pressure washing units should not be
used. If grass has dried on to the c utterhead casing
it can be removed by scraping. If necessary, give
the underside a touch of paint to prevent rusting.
Clean the silencer and the surrounding
area regularly to remove grass, dirt and
flammable w aste products.
Note that you should clean the area under the timing gear casingonce or twice a year. Set at thelowestmowingheight.Slackenthescrewsand remove
the timing gear casing (fig. 9). Clean with a brush
or compressed air.

The inside of the drive wheels should be cleaned
once a season. To clean a wheel, remove the hub
cap, screw, washer,and wheels. Brush or blow the
gear and the gear ring on the wheel to clean them
from grass and dirt (fig. 10). Remount the wheel.
BAT TERY (Tornado 51 SE)
Electrolyte in the battery is toxic and
corrosive.It cancause seriouscorrosion
damage etc. Avoid al l contact with skin,
eyes and clothing.
In normal use during the season, the battery is
chargedby the engine. If the engine cannot be started with the starterkey,it maybe because the battery
is 'dead'. Connect thebattery chargerto the terminal
on the battery and put on charge for 24 hours (fig.
17). On completion of charging,connect thebattery
terminal to the terminal on the motor.
Note! The battery charger must not be connected
to the engine terminal. The engine cannot be started by using the charger as a source of power supply, and the charger will be d amaged.
WINTER STORAGE
Store the lawn mower for the winter with the batterywell-charged in a dry and cool place(between
0° C and +15° C). At least once during the winter
storage period the battery should be maintenancecharged. Before the start of the season the battery
should be charged once again for 24 hours.
COOLING SYSTEM
Before use, the engine's cooling system should be
cleaned. Clean the cylinder's cooling fins and the
airintake,removinganygrasscuttings,dirt and the
like.
LUBRICATION
Set at the lowest mowing height. Slacken the
screws and remove thetransmission casing (fig. 9).
Lubricate the driveshaft by the plastic bushings/
slide bearings I with oil or oil spray at least once a
season (fig. 11).
CHANGING OIL
Change the oil the first time after 5 hours of operation, and subsequently after every 50 hours of operation or once a season. Remove the oil dipstick
andallow the oiltorun outintoa vessel.Be careful
nottoletanyoilrunontothegrass.
Fill with new oil: use oil of SAE 30 or SAE 10W30 quality. The crankcase holds approx. 0.6 litre.
Fill until the oil reaches the “FULL/MAX” mark
on the dip stick.
AIR FILTER
A dirty and b locked air filter reduces the engine
output and increases engine wear.
Clean the filter every three months or after every
25 hours of use, which ever occurs first. More often if the lawn mower is used on dusty ground.
Briggs &StrattonLS45: Carefully remove theair
cleaner so that no dirt falls down into the carburettor (fig. 12). Take out the foam plastic filter element and washit in liquid detergent andwater.Dry
the filter element. Pour a little oil on the filter element and squeeze it in. Refit the air cleaner.
Briggs &Stratton XTE 60:Loosen the screwand
fold down the cover of the air cleaner . Carefully
remove the filter cartridge (fig. 13). Knock it
against a flat surface. Replace the filter cartridge
withanewoneifitisstilldirty.
SPARKING PLUG
Neverremovethesparkplugortheignition lead when checking to see if there is
any spark, always use an approved test
instrument.
Clean thesparking plug regularly (every 100 hours
running). Use a wire brush for cleaning and adjust
the c orrect spark gap 0,75 mm (fig. 14).
Change the sparking plug if the electrodes are excessively burnt or if the plug is damaged. The recommendations of the engine manufacturers are as
follows:
Champion J19LM (RJ19LM) or another equivalent spark plug ought to be used in Briggs & Stratton engines.
Replace the oil when the engine isw arm
and the fuel tank is empty. Take care

ENGLISH
1. Remove the transmission cover by unscrewing
the screws S (fig. 9).
2. When the clutch loop is released it should be
possible to pull the mower backwards without
any resistance. If this is not the case, loosen the
locking nut U and screw inthe nipple Tuntil the
mower can be moved backwards (fig. 15).
3. When the clutch loop is
pressed in approx. 2 cm (position 1) there should be some
resistance when moving the
mower backwards. With the
clutch loop fully pressed in
(position 2) it should not be
possible to pull the mower
backwards. Loosen the locking nut U and screw out the
nipple T until this position is
achieved.
4. Finally tighten the locking nut U.
CHANGING BLADES
Useprotectiveglovestopreventcuts
when changing blades.
SHARPENING OF THE BLAD ES
Sharpening of the blades must be done by wet
method grinding, using a whetstone or a grindstone.
For the sake of safety, the blades should not be
sharpenedonanemerywheel.Averyhightemperature could cause the blade to become brittle.
Once the blade has been sharpened, it
must then be balanced so as to avoid vibration damage.
STORAGE
WINTER STORAGE
Empty the fuel tank. Start the engine and let it run
until it stops. The same petrol must not remain in
the tank for more than one month.
Tip up the mower and screw out the sparking plug.
Pour a teaspoon of engine oil in the sparking plug
hole.Pull out the starting handle slowly so that the
oil is distributed in the cylinder. Screw in the
sparking plug.
Blunt and da maged blades tear off the grass and
spoil the look of the lawn after mowing.New, well
sharpened blades cut the grass cleanly, so that the
lawn looks green and fresh even after mowing.
Always check the blade after an impact. First disconnect the ignition cable. If the blade system has
been damaged the defective parts must be
changed. Always use genuine spare parts.
To replace the blade, slacken the screw (fig. 16).
Fit the new blade so that the stamped STIGA logotype is turned facing the blade attachment (and
not facing the grass). Refit as illustrated. Tighten
thescrewfullytoatorqueof40Nm.
When replacing the blade, the blade screw should
also be replaced.
The guarantee does not cover damage to the blade,
blade holder or engine caused by running into obstacles.
When replacing the blade, the blade holder and
blade screw, always use original spare parts. Nonauthentic spare parts could lead to the risk of personal injury or damage, even if they fit the machine.
Thoroughly clean themowerand storeit indoors in
a dry place.
