USING THE MOWER
BEFORE STARTING
FILL THE CRANKCASE WITH OIL
The lawnmower is delivered without 
any oil in the engine crankcase. The 
crankcase must be filled with oil before 
the engine is started for the first time.
Remove the oil dipstick (fig . 7-9). Fill the engine’s 
crankcase with 0.55 litres of good quality oil (serv-
ice class SE, SF or SG).  Use SAE 30 or SAE 10W-
30 oil.
Fill until the oil reaches the “FULL/MAX” mark 
on the dipstick. Do not overfill.
CHECK 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.
Briggs Stratton:
Remove and wipe off the dipstick (fig. 7). Slide it 
down completely  and tighten it. Unscrew and pull it 
up again. Read off the oil le vel. If the oil level is low, 
fill with oil up to the ‘FULL/MAX’ mark.
Honda:
Remove and wipe off the dipstick (fig. 8, 9). Insert 
the dipstick fully, but do not screw it into the 
thread. Pull it up again. Read off the oil level. If the 
oil level is low, fill with  oil up to the ‘FULL/MAX’ 
mark. 
						

							
ENGLISHGB
FILL UP THE PETROL TANKFill with petrol before starting the en-
gine. Never remove the filler cap or fill 
with petrol while the engine is running 
or still warm.
Never completely fill the petrol tank. Al-
low a little room for the petrol to expand 
if necessary.
Some engines have an extra safety cover under the 
regular fuel cap. This must not be reinstalled.
Preferably use an envir onmentally friendly petrol, 
i.e. alkylate petrol. This type of petrol has a com-
position that is less harmful to people and nature. 
It has e.g. no lead additives, no oxygenators (alco-
hols and ethers), no alkenes and no benzene.
NOTE! If you change to environmental-
ly friendly petrol in an engine previously 
run on ordinary lead-free petrol (95), 
the petrol manufacturer’s recommenda-
tions must be followed carefully. 
Ordinary lead-free 95 octane petrol can also be 
used. You must never use 2-stroke petrol mixed 
with oil.
NOTE! Bear in mind that petrol is a perishable, do 
not purchase more petrol than can be used within 
30 days.
STARTING THE ENGINE
(Briggs & Stratton)
1. Place the lawnmower on flat, firm ground. Do  not start in long grass.
2. Make sure the spark plug cable is connected to  the spark plug.
3. When starting a cold engine: Press down the  primer fully 6 times (fig. 11).
When starting a warm engine the primer does 
not need to be used. If the engine stops due to a 
lack of fuel, refill and press down the primer 3 
times.
3. PRO 51S:  Set the clutch control  M to   (fig. 
16).
4. Press the Start/Stop loop G towards the handle. 
NOTE! The Start/Stop loop G must be kept 
pressed in to prevent the engine stopping 
(fig. 13-16). 5 Grasp the starter handle and start the engine by 
pulling briskly on the starter cord.
For ease of starting, press down
the handle so that the fr ont wheels lift slightly 
from the ground.
Keep hands and feet away from the ro-
tating blade(s). Never put your hand or 
foot under the blade casing or in the 
grass ejector while the engine is run-
ning.
STARTING THE ENGINE (Honda)

tating blade(s). Never put your hand or 
foot under the blade casing or in the 
grass ejector while the engine is run-
ning.
TRANSMISSION
(Multiclip 51S)
Engage the drive by pressing the clutch loop  I to-
wards the handle. Disengage the drive by releasing 
the clutch loop  I (fig.  14).
By pressing down the handlebar so that the driving 
wheels are raised slightly  from the ground, turning, 
reversing, moving round trees, etc., can be per-
formed without having to disengage the drive sys-
tem. 
						

							
ENGLISHGB
TRANSMISSION (PRO 51S)
Engage the drive by moving the clutch control M 
to   (fig. 16). Make sure the clutch control is al-
ways moved fully either to one or the other posi-
tion.
By pressing down the handlebar so that the driving 
wheels are raised slightly  from the ground, turning, 
reversing, moving round tr ees, etc., can be per-
formed without having to disengage the drive sys-
tem.
STOPPING THE ENGINE
The engine may be very warm immedi-
ately after it is shut off. Do not touch the 
silencer, cylinder or cooling flanges. 
This can cause burn injuries.
1. PRO 51S:  Disengage the drive. Set the clutch 
control  M to   (fig. 16).
Honda:  Close the fuel tap.
2. Release Start/Stop loop   Gto stop the engine 
(fig.  13-16). This loop must not be disengaged 
(e.g. by setting it in the depressed position 
against the handle), as it  will not be possible to 
stop the engine.
3. If the lawnmower is left unattended, remove the  spark plug cable from the spark plug. 
If the start/stop loop ceases to work, stop 
the engine by removing the spark plug 
cable from the spark plug. Immediately 
take the lawnmower to an authorised 
workshop for repair.
MOWING TIPS
Before mowing the lawn, take care to remove any 
stones, toys and other hard objects.
A machine with the MULTICLIP system cuts the 
grass, chops it finely and then blows it down into 
the lawn. The grass clippings do not need to be col-
lected.
The following rules should be observed to give the 
best MULTICLIP 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.
3. Ensure that the area under the mower casing is  always kept clean.
4. Always use a well-sharpened blade.
5. Avoid mowing when the grass is wet. The grass  sticks more easily to the underside of the cas-
ing, giving poorer mowing results.
CUTTING HEIGHT
Shut off the engine before adjusting the 
cutting height.
Do not set the cutting height so low that 
the blade(s) come into contact with une-
ven ground.
The mower has single-lever control for adjusting 
the cutting height. Pull the lever outwards and then 
set the mowing height to a position suitable for the 
state of the lawn (fig. 17).
MAINTENANCE
No servicing is to be carried out on the 
engine or mower unit without first 
switching off the engine and removing 
the spark plug cable from the spark 
plug.
Stop the engine and remove the spark 
plug cable if the mower is to be lifted, 
e.g. during transportation.
If the lawnmower needs to be tilted, it 
must be tilted so that the engine’s spark 
plug faces upwards. Tilt the lawnmower 
when the fuel tank is empty.
COOLING SYSTEM
Before each use, the engine’s cooling system must 
be cleaned. Clean the cylinder’s cooling flanges 
and air intake of grass remains, dirt, etc.
CLEANING
After use, the mower should be cleaned. This is 
particularly important on the underside of the 
mower casing. Rinse clean with the garden hose. 
The mower will then last longer and work better.
NOTE! High-pressure washers should not be used. 
If grass has dried on to the mower casing, it can be 
scraped clean.
Clean the silencer and the surrounding 
area regularly to remove grass, dirt and 
flammable waste products.
Multiclip 51S/PRO 51S:  NOTE! Once or twice 
during the mowing season, cleaning should be car-
ried out under the transmission casing (fig. 18). 
Remove the transmission casing and clean with a 
brush or blow with compressed air. 
						

							
ENGLISHGB
OIL CHANGE
Change the oil when the engine is warm 
and the fuel tank is empty. In order to 
prevent burns, take care while draining 
as the oil is hot.
Change the oil the first time after 5 hours of oper-
ation, and subsequently every 50 hours of opera-
tion or once a season. Remove the dipstick, tilt the 
mower and let the oil run out into a container. Be 
careful not to let any oil run on to the grass.
Fill with new oil: Use  SAE 30 or SAE 10W-30 oil. 
The crankcase holds approx.  0.55 litres. Fill until 
the oil reaches the “FULL/MAX” mark on the dip-
stick. Do not overfill.
AIR FILTER
A dirty and blocked air filter reduces the engine 
output and increases engine wear.
Briggs & Stratton (fig. 20): Undo the screw and 
fold down the cover of the air cleaner. Carefully re-
move the filter cartridge.  Knock it against a flat 
surface. Replace the filter cartridge with 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 fre-
quently if the engine is working on dusty ground.
Honda (fig. 21):   Remove the cover and take out the 
filter. Carefully check the filter for holes or other 
damage. A broken or damaged filter must be re-
placed. 
To remove dirt, carefully knock the filter several 
times against a hard surface or use compressed air 
from the back of the filter  to blow-clean. Do not try 
to brush the filter clean as this forces dirt down into 
the fibres. A very dirty  filter should be replaced.
Clean the air filter after every 25 hours of opera-
tion or once a season. More frequently if the en-
gine is working on dusty ground.
SPARK PLUG
Never remove the spark plug or spark 
plug cable when checking to see if there 
is a spark. Use an approved test instru-
ment.
Clean the spark plug regularly (every 100 hours of 
operation). Use a wire brush for cleaning. 
Change the spark plug if the electrodes are exces-
sively burnt or if the plug is damaged. The engine 
manufacturers give the  following recommenda-
tions (fig. 6): Briggs & Stratton:
 Champion J19LM (RJ19LM), 
Spark gap 0.7 - 0.8 mm.
Honda:  BPR6ES (NGK).
Spark gap 0.7 - 0.8 mm.
ADJUSTING THE CLUTCH CABLE 
(Multiclip 51S)
If the drive does not engage when the clutch loop 
is pressed against the handle, or if the lawnmower 
feels cumbersome or slow, this may be because the 
clutch in the transmission  is slipping. To rectify 
this situation, adjust th e clutch cable as follows:
1. When the clutch loop is  released, it should be 
possible to push the mower without any resist-
ance. If this is not the case, screw in the nipple 
T  until the mower can be pushed (fig.  22).
2. When the clutch loop is 
pressed in approx. 2 cm (posi-
tion 1), there should be some 
resistance when pushing the 
lawnmower. With the clutch 
loop fully pressed in (position 
2) it should not be possible to 
push the mower. Unscrew the 
nipple T until this position is 
achieved.
ADJUSTING THE CLUTCH CABLE 
(PRO 51S)
Check the clutch function (fig. 23):
1. Push the mower forwards and backwards with  disengaged transmission.
2. Set the clutch control to the   position and  push the mower until the front wheels engage.
3. In this position, the spring  H should be extend-
ed 6 mm from it’s unloaded position to provide 
sufficient locking force in the transmission. 
4. If the spring is not extended sufficiently, adjust  the wire nipple  I at the handlebar.
5. First loosen the locking nut S and then adjust  the nipple  I.
6. Set the clutch control to the   position and  check that the transmission is disengaged by 
rolling the mower forwards and backwards.

ADJUSTING DRIVE BELT
(Multiclip 51S, PRO 51S)
Check the belt tension regularly. The drive belt is 
correctly adjusted when the shoulder bolt K is cen-
tred in the front hole on the engine bracket
(fig. 24).
Incorrect belt tension can bring about abnormal vi-
brations in the handle (the belt is tensioned too 
tightly) or the belt can start to slide (the belt is not 
tensioned enough).
Adjust the drive belt as follows (fig. 24): 
Stop the engine and remove the spark plug cable 
from the spark plug. Dismantle the transmission 
casing. Undo the screw  L. Pull the transmission 
forwards so that the belt is tensioned and tighten 
the screw  L. The drive belt must be adjusted so that 
the shoulder bolt  K is centred in the front hole on 
the engine bracket.
SHOCK-ABSORBER 
(PRO 48, PRO 51S)
Fig. 19. Check the shock-absorber and the insulat-
ing sleeves twice per season. Replace in the event 
of damage or wear.
CHANGING BLADES
Wear protective gloves when changing 
blades to avoid cutting yourself. 
Blunt and damaged blades tear up the grass and 
make the lawn unsightly after mowing. New well-
sharpened blades cut off the grass.  This gives a 
green and fresh appearance after mowing.
Always check the blade after an impact. First dis-
connect the spark plug cable. If the blade system 
has been damaged, defective parts should be re-
placed. Always use genuine spare parts.
To replace the blade, undo the screw (fig. 26, 27). 
Fit the new blade so that  the stamped STIGA logo 
is facing the blade holder  (not facing the grass). 
Reinstall as illustrated. Tighten the screw properly. 
Tightening torque 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 ob-
stacles. When replacing the blade, blade holder and blade 
screw, always use genuine spare parts. Non-genu-
ine spare parts can entail a risk of injury or dam-
age, even if they fit the machine.
SHARPENING THE BLADES
Sharpening of the blades must be performed by 
wet grinding, using a whetstone or a grindstone.
For safety reasons, the blades should not be sharp-
ened on an emery wheel. Too high temperature 
could cause the blade to become brittle. 
Once the blade has been sharpened, it 
must then be balanced to avoid vibra-
tion 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 unscrew the spark plug. 
Pour a tablespoon of engine oil into the spark plug 
hole. Pull out the starter  handle slowly so that the 
oil is distributed in the cylinder. Screw in the spark 
plug.
Thoroughly clean the mower and store it indoors in 
a dry place.
SERVICING
Genuine spare parts are  supplied by service work-
shops and by many dealers.
