2 DESCRIPTION
2.1 DriveThe machine has 4-wheel drive. The power from 
the engine to the drive wheels is transferred hy-
draulically. The engine drives an oil pump, which 
pumps oil through the rear and front axle drives. 
The front axle and rear axle are connected in se-
ries, which means that the front wheels and rear 
wheels are forced to rotate at the same speed. 
To make turning easier, both axles are equipped 
with differential. 
Front-mounted implements are powered via drive 
belts.
2.2 SteeringThe machine is articulated. This means that the 
chassis is divided into a front and a rear section, 
which can be turned in relation to each other.
The articulated steering means that the machine 
can turn around trees and other obstacles with an 
extremely small turning radius.
2.3 Safety systemThe machine is equipped with an electrical safety 
system. The safety system interrupts certain activ-
ities that can entail a danger of incorrect manoeu-
vres. For example, the engine cannot be started if 
the clutch-parking brake pedal is depressed.
The operation of the safety system must 
always be checked every time before 
use.
2.4 Controls
2.4.1 Implement lifter, mechanical (3:C)
(Pro16)
To switch between working position and transport 
position:
1. Depress the pedal fully. 
2. Release the pedal slowly.
2.4.2 Implement lifter, hydraulic (5:M)
(Pro20, Pro25, Pro Svan)
The hydraulic implement lifter only 
works when the engine is running, and is 
controlled with the switch (5:M). 
The switch has the following three positions:
•Floating position. Press the front part of the 
switch. The switch locks in the pressed position 
and the implement is lowered until it reaches its 
floating position. 
Floating position means that the implement al-
ways rests with the same pressure against the 
ground and can follow the ground’s contours. 
Floating position should be used when working.

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 Pro 16 and Pro 20 (Briggs & Strat-
ton) are filled with SAE 30 oil.
On delivery, the Pro 25 (Kohler) and Pro Svan 
(Honda) are 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.

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.
4.3.1 General safety check
4.3.2 Electrical safety check
The operation of the safety system 
should always be checked every time 
before use.
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

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).
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 
relevant machine/engine.

ENGLISHEN
5.4.1 Change intervals
The table below states hours of operation and cal-
endar months. Carry out the relevant action at 
whichever occurs first.
Change the oil more frequently if the engine has to 
operate in demanding conditions or if the ambient 
temperature is high.
5.4.2 Engine Oil
Use synthetic oil according to the table below.
Use oil without any additives.
Do not fill with too much oil. This can cause the 
engine to overheat. 
Change oil when the engine is warm.The engine oil may be very hot if it is 
drained off directly after the engine is 
shut off. Therefore allow the engine to 
cool a few minutes before draining the 
oil.
1.  Attach the clamp on the oil drainage hose. Use 
a polygrip or similar. See fig. 15-17:Y.
2.  Move the clamp up 3-4 cm on the oil drainage 
hose and pull out the plug.
3. Collect the oil in a collection vessel.
NOTE! Do not spill any oil on the drive belts.
4. Hand in the oil for disposal in accordance with 
local provisions.
5. Install the oil drainage plug and move the clamp 
back so that it clamps above the plug.
6. If the oil filter is to be replaced, see 5.4.3 below 
before continuing.
7.  Remove the dipstick and fill with new oil.
Oil quantity:
8. After filling up the oil, start the engine and idle 
for 30 seconds. 
9. Check to see if there is any oil leakage.
10.Stop the engine. Wait for 30 seconds and then 
check the oil level in accordance with 4.2.
5.4.3 Oil filter
First drain the engine oil and install the oil drain-
age plug as described above. Then replace the oil 
filter as follows:
Pro 16, Pro 20, Pro Svan:
1. Clean the area around the filter and dismantle 
the filter.
2. Moisten the new filter’s gasket with oil.
3. Install the filter. First screw in the filter so that 
the gasket comes into contact with the engine. 
Then screw in the filter a further 1/2-3/4 turn.
4. Continue with point 7 in accordance with 5.4.2 
Engine Oil above.
Pro 25:
1. Clean the area around the filter and dismantle 
the filter.
2. Place the new filter with the hole facing up-
wards in a vessel.
3. Fill up with the new engine oil through the hole 
in the filter until the level reaches the bottom of 
the thread.
4. Wait 1-2 minutes so that the oil is absorbed by 
the filter material.
5. Moisten the filter’s gasket with oil. Machine1st time Then at
