2.4.17 Seat (1:T)
The seat can be folded and adjusted front-
rear. The seat can be adjusted as follows:
1. Move the control lever (1:T) upwards.
2. Set the seat to the desired position.
3. Release the control lever (1:S) to lock 
the seat.
The seat is equipped with a safety switch that is 
connected to the machine’s safety system. This 
means that certain dangerous activities are not pos-
sible when there is nobody sitting on the seat. Also 
see 4.3.2.
2.4.18 Engine casing (7:U)
In order to access the fuel cock, battery 
and engine, the machine has an engine 
casing that can be opened. The engine cas-
ing is locked with a rubber strap.
The engine casing is opened as follows:
1. Undo the rubber strap (7:V) at the front edge of 
the casing.
2. Carefully lift the engine casing back.
Close in the reverse order.
The machine may not be operated un-
less the engine casing is closed and 
locked. Risk of burns and crushing in-
juries.
2.4.19Quick-release mounting (34:H)
The quick connections can be separated, 
which makes it very easy to shift between 
the different implements.
The quick connections allow the deck to 
be moved easily between the two posi-
tions:
• Normal position with fully tensioned belt.
• 4 cm behind the normal position with slackened 
belt so that the deck gets closer to the base ma-
chine.
As the belt idler is released from the belt, the quick 
connections simplify belt and deck replacement, 
and also make shifting to the washing position and 
service positions easier.
Releasing the belt tension:
1. Remove the locking pins (34:G) from both 
sides.
2. Open the quick connections by depressing their 
rear sections with your heel. See (34:F).
When the quick connections are 
opened, the deck arms rest loosely in 
the shaft sections. The deck must never 
be set to the service position or washing 
position without relocking the quick 
connections after unhooking the deck 
belt.3. Carry out the necessary corrective action, e.g.:
• Unhook the belt.
• Replace the deck by unhooking the deck 
arms. See fig. 36.
Tensioning the belt:
First tension one side and then the other according 
to the instructions below.
Do not turn the lever using your hands. 
Risk of crushing injuries.
1. Place your foot on the lever (34:J) and carefully 
turn a half turn forwards.
2. Install the locking pin (34:G).
3. Carry out the above on the other side.

4 STARTING AND OPERATION
The machine may not be operated un-
less the engine casing is closed and 
locked. Risk of burns and crushing in-
juries.
4.1 Filling with petrolAlways use lead-free petrol. You must never use 2-
stroke petrol mixed with oil.
The tank holds 14 litres. The level can easily be 
read through the transparent tank.
NOTE! Ordinary lead-free petrol is a perishable 
and must not be stored for more than 30 days.
Environmental petrol can be used, i.e. alkylate 
petrol. This type of petrol has a composition that is 
less harmful for people and nature.
Petrol is highly inflammable. Always 
store fuel in containers that are made 
especially for this purpose. 
Only fill or top up with petrol outdoors, 
and never smoke when filling or top-
ping up. Fill up with fuel before starting 
the engine. Never remove the filler cap 
or fill with petrol while the engine is 
running or still warm.
Never completely fill the petrol tank. Leave an 
empty space (= at least the entire filler tube plus 1 
- 2 cm at the top of the tank) to allow the petrol to 
expand when it warms up without overflowing. 
See fig. 8.
4.2 Checking the engine oil levelOn delivery, the crankcase is filled with SAE 10W-
40 oil.
Check the oil level every time before using to 
ensure it is correct. The machine should be 
standing on level ground.
Wipe around the dipstick. Unscrew and 
pull it up. Wipe the dipstick. 
Pro 16, Pro 20, Pro25:
Push the dipstick down completely and screw into 
place. 
Unscrew and pull the dipstick up again. Read off 
the oil level.
Pro Svan:
Push the dipstick down completely without screw-
ing it into place. Pull it up again and read off the oil 
level.
Top up with oil to the “FULL” mark if the oil level 
is below this mark. See fig. 9-11.
The oil level must never exceed the “FULL” mark. 
This results in the engine overheating. If the oil 
level exceeds the “FULL” mark, the oil must be 
drained until the correct level is achieved.
4.3 Safety checksCheck that the results of the safety checks below 
are achieved when testing the machine in question.
The safety checks must always be car-
ried out every time before use.
If any of the results below is not 
achieved, the machine must not be 
used! Take the machine to a service 
workshop for repair.

4.4 Start1.  Open the fuel cock. See 14.
2.  Check that the spark plug cable(s) is/are in-
stalled on the spark plug(s).
3.  Check to make sure that the power take-off is 
disengaged. 
4.  Do not keep your foot on the drive pedal (3:F). 
5. Put the throttle control at full throttle. 
Starting cold engine – pull the choke control out 
fully. 
Starting warm engine – the choke control 
should be pressed in.
6.  Depress the clutch-brake pedal (3:B) fully.
7.  Turn the ignition key and start the engine.
8 Once the engine has started, push the choke 
control in gradually if it has been used. 
9. When starting from cold, do not make the ma-
chine work under load immediately, but let the 
engine run for a few minutes first. This will al-
low the oil to warm up. 
When the machine is in operation, full throttle 
should always be used.
4.5 Power assisted steering 
(Pro20, Pro25, Pro Svan)
Power assisted steering means that power from the 
machine’s hydraulic system is supplied to the 
steering wheel movements. This makes the ma-
chine very easy to steer when the engine is operat-
ing at working revs (full throttle). 
The servo effect is reduced as the engine speed 
drops.
4.6 Operating tipsAlways check that there is the correct volume of 
oil in the engine. This is particularly important 
when operating on slopes. See 4.2. 
Be careful when driving on slopes. No 
sudden starting or stopping when driv-
ing up or down a slope. Never drive 
across a slope. Move from the top down 
or from the bottom to the top. 
The machine may not be driven on 
slopes greater than 10º in any direction.Reduce the speed on slopes and when 
making sharp turns in order to retain 
control and reduce the risk of tipping 
over.
Do not turn the steering wheel to full 
lock when driving in top gear and at full 
throttle. The machine can easily topple 
over.
Keep hands and fingers well away from 
articulated steering joint and seat 
bracket. Risk of crushing injuries. Nev-
er drive with the engine casing open.
4.7 StopDisengage the power take-off. Apply the parking 
brake. 
Allow the engine to idle 1-2 mins. Stop the engine 
by turning off the ignition key.
Shut off the petrol cock. This is particularly impor-
tant if the machine is to be transported on a trailer 
for example.
If the machine is left unattended, re-
move the spark plug cable(s) and re-
move the ignition key.
The engine may be very warm immedi-
ately after it is shut off. Do not touch the 
silencer, cylinder or cooling fins. This 
can cause burn injuries.
4.8 Cleaning
To reduce the risk of fire, keep the en-
gine, silencer, battery and fuel tank free 
from grass, leaves and oil.
To reduce the risk of fire, regularly 
check the machine for oil and/or fuel 
leakage. 
Clean the machine after each use. The following 
instructions apply for cleaning:
• When washing the machine with water under 
high pressure, do not point the jet directly at 
axle seals, electrical components or hydraulic 
valves.
• Do not spray water directly at the engine. 
• Clean the engine with a brush and/or com-
pressed air.
• Clean the engine’s cooling air intake (9-11:W).
• Only Pro25: Clean the oil cooler (12:X). Status Action Result

5 MAINTENANCE
5.1 Service programmeIn order to keep the machine in good condition as 
regards reliability and operational safety as well as 
from an environmental perspective, STIGA’s Ser-
vice programme should be followed.
The contents of this programme can be found in 
the attached service log.
Basic service
 must always be carried out by an au-
thorised workshop.
First service and intermediate service
 should be 
carried out by an authorised workshop, but can 
also be carried out by the user. The content of this 
can be found in the service log and the actions are 
described under “4 STARTING AND OPERA-
TION” as well as below.
Servicing carried out at an authorised workshop 
guarantees professional work using genuine spare 
parts.
At each basic service and intermediate service car-
ried out at an authorised workshop, the service log 
is stamped. A service log presenting these services 
is a valuable document that improves the ma-
chine’s second-hand value.
5.2 PreparationAll service and all maintenance must be carried out 
on a stationary machine with the engine switched 
off.
Prevent the machine from rolling by al-
ways applying the parking brake.
Stop the engine.
Prevent unintentional starting of the 
engine by disconnecting the spark plug 
cable(s) from the spark plug(s) and re-
moving the ignition key. 
5.3 Tyre pressureAdjust the air pressure in the tyres as follows:
Front: 0.6 bar (9 psi).
Rear: 0.4 bar (6 psi). 
5.4 Changing engine oil, filterThis section contains tables covering the different 
engines that are included in STIGA’s Pro range. To 
facilitate reading, mark the data that applies to the

If acid comes into contact with the eyes 
or skin, this can cause serious injuries. 
If any part of the body has come into 
contact with acid, rinse immediately 
with copious amounts of water and seek 
medical assistance as soon as possible.
The battery is a valve-regulated battery with 12 V 
nominal voltage. The battery fluid does not need to 
and cannot be checked or topped up. The only 
maintenance that is required is charging, for exam-
ple after extended storage.
The battery must be fully charged be-
fore being used for the first time. The 
battery must always be stored fully 
charged. If the battery is stored while 
discharged, serious damage will occur.

							73
ENGLISHEN
ble from the battery’s negative terminal (-). 
Then disconnect the red cable from the battery’s 
positive terminal (-).
• During installation. First connect the red cable 
to the battery’s positive terminal (+). Then con-
nect the black cable to the battery’s negative ter-
minal (-).
If the cables are disconnected/connect-
ed in the wrong order, there is a risk of 
a short-circuit and damage to the bat-
tery.
If the cables are interchanged, the gen-
erator and the battery will be damaged.
Tighten the cables securely. Loose ca-
bles can cause a fire.
The engine must never be driven with 
the battery disconnected. There is a risk 
of serious damage to the generator and 
the electrical system.
When the battery has been rectified, install the fuel 
tank as follows:
Check that the petrol hose is not 
clamped against the hydraulic pump 
and does not come into contact with 
this. The hydraulic pump becomes very 
hot during operation. Risk of fire.
