ASSEMBLING
HANDLE: LOW ER PART
(PRO 48/PRO 51S)
BEFORE STARTING
FILL THE CRANKCASE WITH OIL
The lawn mower is delivered without
any oil in the motor crankcase. The
crankcase must, therefore,befilled with
oil before the motor is started the first
time.
Remove the oil dipstick (fig. 7, 8, 9). Fill the engine's crankcase with 0.6 litres of good quality oil
(service class SE, SF or SG). Use SAE 30 or SAE
10W-30 oil.
Slowly fill up to the “FULL/MAX” mark. 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. The mower should stand level.
Remove and dry the dipstick (fig. 7, 8, 9). Slide it
down completely and tighten it. Unscrew and pull
itup again.Read-off.Iftheoil levelislow,fillwith
oil up to the “FULL/MAX” mark.
Fold back and screw tight the lower part of the
handle using the screws A (fig. 1).
HANDLE: UPPER PART
Fit the upper part of the handlebar (fig.2). The
height of the handlebar above the ground can be
adjusted within certain limits since the lower part
is provided with slotted holes at the rear (fig. 3).
FILL UP THE PETROL TANK
Fill with petrol before starting th e motor. Never removethe filler cap or fill
with petrol while the mo tor is running
or still warm.
Neverfill the fuel tank completely full
but allow a little room for the petrol to
expand.
Always use pure unleaded petrol. You must never
use 2-stroke petrol mixed with oil.

be disengaged (e.g. through fixing it in the depressed position against the steering), as t he engine cannot be stopped.
3. If the lawn mower is left unattended to, remove
the lead from the spark plug.
Multiclip51SE: Also remove the starter key.
If the start/st op 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.
MOWING TIPS
Before mowing the lawn, take care to remove any
stones toys and other hard objects.
A machine with MULCHER system cuts thegrass,
chops it finely and then blows it down in the lawn.
The grass clippings need not to be collected.
The following rules should be observed to give
best MULCHER effect:
1. Use a high engine speed (full throttle).
2. Do not cut the grass too short. Not more than 1/
3rd of the length should be cut off.

off the motor and removing the spark
plug cable from the spark plug.
Stop the motor and remove the spark
plug cable if the mower is to be lifted,
e.g. with transportation.
If the lawn mower needs to be tilted i t
should be tilted so that the spark plug
faceupwards. Tiltthelawnmowerwhen
the fuel tank is e mpty.
COOLING SYSTEM
Beforeusing the lawn mower,the engine'scooling
system must be cleaned. Clean the cylinder's cooling flanges and air inlet to make sure they are free
from grass, dirt, etc.
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.
3. Always keep it clean under the mower casing.
4. Always use a well sharpened blade.
5. Avoid mowing when the grassiswet. Thegrass
then sticks to the undersideof the casing, giving
poor mowing results.
CUTTING HEIGHT
Shut off the motor before adjusting the
cutting height.
Do not set the cutting height so low that
the blade/blades can hit uneven ground.
The mower has single-lever control for adjusting
the mowing height. Pull the lever outwards and
then set the mowing height to a position suitable
for the state of the lawn (fig. 19).
Note! H igh pressure washing units should not be
used. If grass has dried on to the cutterhead casing
it can be removed by scraping.
Clean the silencer and the surrounding
area regularly to remove grass, dirt and
flammable waste products.
Multiclip 51S/51SE/PRO 51S: Note! Cleaning
should be done under the transmission cover (fig.
20) once or twice during the mowing season. Remove the transmission casing and clean with a
brush or blow with compressed air.
CHANGING OIL
Replace the oil when the engine is warm
and the fuel tank is empty.Take care
whiledrainingastheoilishot,thisisto
preventburns.
Change the oil the first time after 5 hours of operation, and subsequently after every 50 hours of operationor once a season. Remove the dip stick, tilt
the mower and let the oil run out into a container.
Be careful not to let any oil run on to the grass.

ENGLISH
Fill wi th 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. Do not fill with too much oil.
AIR FILTER
A dirty and blocked air filter reduces the engine
output and increases engine wear.
Briggs & Stratton LS 45 (fig. 21): Carefully remove the air cleaner so thatno dirtfalls down into
the carburettor. Take out the foam plastic filter element and wash it in liquid detergent and water.
Dry the filter element. Pour a little oil on the filter
element and squeeze it in. Refit the air cleaner.
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 & Stratton XTE 50, INTEK (fig. 22):
Loosen the screw and fold down the cover of the
air cleaner. Carefully remove the filter cartridge.
Knock it against a flat surface. Replace the filter
cartridge w ith a new one if it is still dirty.
Clean the filter every three months or after every
25 hours of use, whichever occurs first. More often
if the lawn mower is used on dusty ground.
Honda (fig. 23): Remove the cover and take out
thefilter. Carefullycheckthe filterfor holesor other damage. A broken or damaged filter must be replaced.
on the battery and put on charge for 24 hours. On
completion of charging, connect the battery terminal to the terminal on the motor.
Note! The battery charger mustnot 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 damaged.
WINTER STORAGE
Store the lawn mower for the winter with the batterywell-chargedin a dry and cool place(between
0° C and +15° C). At least once during the winter
storage period the b attery should be maintenancecharged. Before the start of the season the battery
should be charged once again for 24 hours.
SPARKING PLUG
Neverremovethesparkplugortheignition lead when checking to see if there is
any spark, always use an approved test
instrument.
Clean the sparking plug regularly (every 100 hours
running). Use a wire brush for cleaning.
Change the sparking plug if the electrodes are excessively burnt or if the plug is damaged. The recommendations (fig. 24) of the engine
manufacturers are as follows:
Briggs & Stratton: Champion J19LM (RJ19LM).
Spark gap 0.76 mm.
To remove dirt, carefully knock the filter several
times against a hard surface or use compressed air
from the backof the filter to blow-clean. Do nottry
tobrush thefilter clean as this forces dirt downinto
the fibres. A very dirty f ilter should be replaced.
Clean the air filter after every 25 hours of use or
once a season. More often if the lawn mower is
used on dusty ground.
BATTERY (Multiclip 51SE)
Electrolyte in the battery is toxic and
corrosive.It can causeseriouscorrosion
damage etc. Avoid all contact wi th skin,
eyes and clothing.
In normal use during the season, the battery is
chargedby the engine. If the engine cannot be started withthe starter key,it may be because the battery
is 'dead'.Connect the battery chargerto the terminal

ADJUSTING THE CLUTCH CABLE
(Multiclip 51S/51SE)
If the drive does not engage when the coupling
clamp is pressed against the handle, or if the lawn
mower feels cumbersome or slow, the reason may
be that the coupling in the transmission slips. To
rectify this situation, adjust the clutch cable as follows:
1. When the clutch loop is released, it should be
possible to push the mower without any resistance. If this is not the case, screw in the nipple
T until the mower can be pushed (fig. 25).
10
Page 10
ENGLISH
GB
2. When the clutch loop is
pressed in a pprox. 2 cm
(position 1), there should
be some resistance when
moving the lawn mower.
With the clutch loop fully
pressed in (position 2, it
should not be possible to
movethe mower. Unscrew
the nipple T untilthis position is achieved.
ADJUSTING THE CLUTCH CABLE
(PRO 51S)
Control the clutch function (fig. 26):
1. Push the mower forwards and backwards with
disengaged transmission.
2. Set the clutch control to theposition and
push the mover until the front wheels engage.
3. In this position the spring H should then be extended 6 mm from it's unloaded position to give
a sufficent lockforce in the transmission.
4. If the spring is not extended enough, adjust the
wire nipple I at the handlebar.
5. First loosen the lock nut S and then adjust the
nipple I.
6. Set the clutch control to theposition and control that the transmission is disengaged by rolling the mower to and fro.
ADJUSTING DRIVE BELT
(Multiclip 51S, 51SE, PRO 51S)
Check the belt tension regularly. The drive belt is
correctly adjusted when the shoulder bolt K is centered in the front hole of the engine bracket
(fig. 27).
Incorrect belt tension can bring about abnormal vibrations in the steering (the belt is tensioned too
tightly) or the belt can start to slide (the belt is not
tensioned enough).
Adjust the drive belt like this: Stop the engine and
remove the ignition cable from the spark plug. Dismantle the transmission casing. Loosen the screw
L Pull the transmission forwardsso that the belt is
tightened and tighten the screw L. The drive belt
must be adjusted so that the shoulder bolt K centers in the front hole of the engine assembly ring.
SHOCK-ABSORBER
(PRO 48, PRO 51S)
The forward shock-absorberP (fig. 28) takes up a
greater load. Check the shock-absorber twice per
season. If the shock-absorber shows signs of damage or wear it should be replaced.
CHANGING BLADES
Useprotectiveglovestopreventcuts
when changing bla des/ knifeblades.
Blunt and damaged 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. 29).
Fit the new blade so that the stamped STIGA logotype is turned facing the blade attachment (and
not facing the grass). Refit the washer and screw.
Tighten the screw fully to a torque of 40 Nm.
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 genuine spare parts. Nongenuine spare parts could lead to the risk of personal injury or damage, even if they fit the machine.
SHARPENING OF THE BLADES
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 t h e blade has been sharpened, it
must then be balanced so as to avoid vibration damage.
