2. Make sure that the spark plug cable is properly
in place.

3. Check to make sure that the power take-off is
disengaged.

4. Do not keep your foot on the drive pedal.

5a. Comfort-President:
Starting cold engine – put the throttle control in the
choke position. Starting warm engine – put the
throttle control at full throttle (approx. 1 cm behind
the choke position).

5b. Royal-Pro16-Pro20:
Put the throttle control at full throttle. Starting cold
engine – pull the choke control out fully. Starting
warm engine – do not touch the choke control.

6. Depress the brake pedal fully.

7. Turn the ignition key and start the engine.

8a. Comfort-President:
Once the engine has started, move the throttle con-
trol gradually to full throttle if the choke has been
used.

8b. Royal-Pro16-Pro20:
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 en-
gine run for a few minutes first. This will allow the
oil to warm up.

When in use, always operate the engine at full
throttle.

STOPPING

Disengage the power take-off. Apply the parking
brake.

Allow the engine to idle 1 - 2 mins. Stop the engine
by turning off the starter 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 from the
spark plug. Also remove the starter 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.

CATALYTIC CONVERTER
(Pro20 Cat)

The catalytic converter gets very hot during opera-
tion. The heat remains for a long time after the en-
gine has been stopped. Be aware of the fire risk.

Do not park in close proximity to in-
flammable objects. Do not cover the
machine until the catalytic converter
has cooled down.

STEERING AID (Pro20)

Built-in function in order to facilitate steering. The
operator only has to turn the steering wheel gently.
A hydraulic torque amplifier creates the remaining
force.

As opposed to normal servo steering (e.g. in a car),
the steering aid has a limited capacity. This means
that it has some characteristics that might be con-
sidered negative:
- at a low engine rpm or in situations where extra

steering force is needed, steering can be consid-
ered to be “jumpy”.

- the machine should always be moving when the

steering is used. Avoid turning the steering
wheel when the machine is standing completely
still and the accessory is in the lowered working
position.

The steering is adapted in order to produce better
results at a normal working speed. This produces
major benefits.

Even when the engine is not running, the steering
works. However, it is harder to turn in this case, if
the machine is to be manoeuvred manually.

DRIVING TIPS

Make sure that there is the correct quantity of oil in
the engine when driving on slopes (oil level on
“FULL”).

The machine may not be operated unless the engine casing is mounted. Risk of burns and crushing injuries.

FILLING THE FUEL TANK

6.Sand spreading

Using sand spreader 13-1975. Can also be used for spreading salt. Snow chains 13-0936 (16“)

Always use lead-free petrol. You must never use 2- stroke petrol mixed with oil.

NOTE! Bear in mind that ordinary lead-free petrol is a perishable; do not purchase more petrol than can be used within thirty 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 topping up. Fill 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 (fig. 28).

CHECKING THE ENGINE OIL LEVEL

(President - Comfort - Pro16 - Pro20)

Starting cold engine – put the throttle control in the choke position. Starting warm engine – put the throttle control at full throttle (approx. 1 cm behind the choke position).

5b. Royal-Pro16-Pro20:

Put the throttle control at full throttle. Starting cold engine – pull the choke control out fully. Starting warm engine – do not touch the choke control.

6.Depress the brake pedal fully.

7.Turn the ignition key and start the engine.

8a. Comfort-President:

Once the engine has started, move the throttle control gradually to full throttle if the choke has been used.

8b. Royal-Pro16-Pro20:

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 machine work under load immediately, but let the engine run for a few minutes first. This will allow the oil to warm up.

When in use, always operate the engine at full throttle.

STOPPING

Disengage the power take-off. Apply the parking brake.

If the machine is left unattended, remove the spark plug cable from the spark plug. Also remove the starter key.

The engine may be very warm immediately after it is shut off. Do not touch the silencer, cylinder or cooling fins. This can cause burn injuries.

CATALYTIC CONVERTER

(Pro20 Cat)

The catalytic converter gets very hot during operation. The heat remains for a long time after the engine has been stopped. Be aware of the fire risk.

Do not park in close proximity to inflammable objects. Do not cover the machine until the catalytic converter has cooled down.

STEERING AID (Pro20)

Built-in function in order to facilitate steering. The operator only has to turn the steering wheel gently. A hydraulic torque amplifier creates the remaining force.

As opposed to normal servo steering (e.g. in a car), the steering aid has a limited capacity. This means that it has some characteristics that might be considered negative:

-at a low engine rpm or in situations where extra steering force is needed, steering can be considered to be “jumpy”.

-the machine should always be moving when the steering is used. Avoid turning the steering wheel when the machine is standing completely still and the accessory is in the lowered working position.

The steering is adapted in order to produce better results at a normal working speed. This produces major benefits.

Even when the engine is not running, the steering works. However, it is harder to turn in this case, if the machine is to be manoeuvred manually.

Allow the engine to idle 1 - 2 mins. Stop the engine by turning off the starter key.

Shut off the petrol cock. This is particularly important if the machine is to be transported on a trailer for example.

DRIVING TIPS

Make sure that there is the correct quantity of oil in the engine when driving on slopes (oil level on “FULL”).

Be careful when driving on slopes. No sudden starting or stopping when moving up or down a slope. Never drive across a slope. Move from the top down, and from the bottom to the top.

The machine, equipped with original accessories, may not be driven on slopes greater than 10º in any direction.

Reduce the speed on slopes and when making sharp turns to prevent the machine from tipping over or you losing control of the machine.

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. Never operate the machine without the engine casing.

SERVICE AND MAINTENANCE

SERVICE PROGRAM

In order to keep the machine in good condition, as regards reliability and operational safety as well as from an environmental perspective, STIGA’s service program should be followed.

The contents of this program can be found in the attached service log.

We recommend that an authorised workshop carries out every service. This guarantees that the work is performed by trained personnel and with genuine spare parts.

At every service, the service log should be stamped. A “fully stamped” service log is a valuable document that improves the machine’s secondhand value.

PREPARATIONS

Unless otherwise stated, all service and maintenance must be carried out on a stationary machine when the engine is not running.

Prevent the machine from rolling by always applying the parking brake.

Prevent unintentional starting of the engine by always stopping the engine, disconnecting the spark plug cable from the spark plug and earthing it. Disconnect the negative cable from the battery.

CLEANING

To reduce the risk of fire, keep the engine, silencer/catalytic converter, 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.

When washing the machine with water under high pressure, do not point the jet directly at the transmission.

Do not point jets of water directly at the engine. Use a brush or compressed air in order to clean it.

ENGINE OIL

(President - Comfort - Pro16 - Pro20)

Change the oil for the first time after 5 hours running, and then after every 50 hours running or once a season. Change oil when the engine is warm.

Always use a good grade of oil (service grade SF, SG or SH).

Change the oil more often (after 25 hours of operation or at least once a season) if the engine has to operate under demanding conditions or if the ambient temperature is high.

The engine oil may be very hot if it is drained off directly after the engine is shut off. So allow the engine to cool a few minutes before draining the oil.

1. Oil drain pipe (metal):

Unscrew the oil drain plug at the end of the pipe.

Collect the oil in a collection vessel. Then take the oil to a recycling station. Do not allow oil to get on the V-belts.

2.Screw in the oil drain plug. Make sure that the fibre gasket and the O-ring inside the plug are not damaged and that they are in the correct place.

3.Remove the dipstick and fill up with new oil.

Oil capacity:

Comfort, President - 1.4 l

Pro16, Pro20 - 1.7 l (incl. oil filter)

Oil type, summer (> 4ºC): SAE-30

(SAE 10W-30 can also be used. However, oil consumption may increase somewhat if 10W-30 is used. Therefore, check the oil level more regularly if you use this type of oil).

Oil type, winter (< 4ºC): SAE 5W-30

(if this oil is not available, use SAE 10W-30).

Use oil without any additives.

Do not fill with too much oil. This can cause the engine to overheat.

After filling up the oil, start the engine and idle for 30 seconds. Stop the engine. Wait for 30 seconds and then check the oil level.

Check to see if there is any oil leakage. If necessary, fill up the oil up to the “FULL“ mark.

ENGINE OIL (Royal)

Change the oil for the first time after 20 hours of operation (or during the first month), and then after every 100 hours of operation or once every 6 months.

Change oil when the engine is warm. Always use a good grade of oil (service grade SF, SG or SH).

The engine oil may be very hot if it is drained off directly after the engine is shut off. So allow the engine to cool a few minutes before draining the oil.

Unscrew the oil drain plug at the end of the pipe (fig. 13).

Collect the oil in a collection vessel. Then take the oil to a recycling station. Do not allow oil to get on the V-belts.

Screw in the oil drain plug. Make sure that the fibre gasket and the O-ring inside the plug are not damaged and that they are in the correct place.

Remove the dipstick and fill up with new oil up to the “UPPER” mark.

Oil capacity:

Royal - 0.9 l (= oil quantity at change. In total the engine holds 1.15 l).

Oil type for all seasons: SAE 10W-40.

For extremely low temperatures (< -20° C), use SAE 5W-30.

Stiga Park Pro 16 2wd Manual

Use oil without any additives.

Do not fill with too much oil. This can cause the engine to overheat.

OIL FILTER – ENGINE

(Pro16 - Pro20)

Replace the oil filter after every 100 hours of operation or once a season.

Before screwing the new filter, oil the filter gasket with engine oil.

Screw the filter by hand, until the filter gasket touches the filter attachment. Then tighten ½ to ¾ of a full turn (fig. 14).

Start the engine and idle to see if any leakage occurs. Stop the engine. Check the oil level. If necessary, fill up the oil up to the “FULL” mark.

AIR FILTER - ENGINE

Comfort - President - Pro16 - Pro20:

Clean the foam pre-filter every 3 months or after every 25 hours of operation, whichever comes first.

Clean the paper filter insert once a year or after every 100 hours of operation, whichever comes first.

Royal:

Clean the air filter every 3 months or after every 50 hours of operation, whichever comes first.

Clean the paper filter insert once a year or after every 200 hours of operation, whichever comes first.

All models:

Note! Both filters should be cleaned more often if the machine operates on dusty ground.

1.Remove the protective cover of the air filter (fig.

15- 17).

2.Dismantle the paper filter insert and the foam pre-filter. Make sure that no dirt gets into the carburettor. Clean the air filter housing.

Stiga Park Pro 16 4wd Manual

Clean the catalytic converter’s air filter every 3 months or after every 25 hours of operation, whichever comes first.

1.Remove the cover by pressing in the locking mechanism with a screwdriver etc. (fig. 18).

2.Remove the foam filter and wash it in liquid detergent and water. Squeeze dry. Do not oil the filter.

3.Replace the filter and snap the cover into place.

SPARK PLUG

Only use a Briggs & Stratton sparking tester to check the spark in the sparking plug(s) (fig. 19).

Clean the spark plug after every 100 hours of operation or once a season. For replacing a spark plug, a spark plug sleeve A and a torsion pin B are provided in the accessories bag.

The engine manufacturer recommends:

Royal: NGK BPR5ES or DENSO W16EPR-U President-Comfort-Pro16-Pro20: Champion RC12YC

Correct spark gap: 0.75 mm.

COOLING AIR INTAKE - ENGINE

The engine is air-cooled. A blocked cooling system can damage the engine. The engine should be cleaned at least once a year or every 100 hours of operation.

Remove the fan casing. Clean the cooling fins on the cylinder, the fan and the rotating protective grille. Clean more frequently if mowing dry grass.

BATTERY

electrolyte level.

On delivery, the battery is in the accessories box.

The battery must be fully charged before being used for the first time. The battery should always be stored fully charged. If the battery is stored while totally flat it could sustain permanent damage.

If the machine is not going to be used for an extended period (more than 1 month), the battery should be charged, disconnected and then stored in a cool, safe place. Charge the battery completely before reinstalling.

The battery can be charged in two ways:

1.Via a battery charger (recommended). This must be a charger with constant voltage. The battery can be damaged if a standard type battery charger (for acid batteries) is used.

Stiga recommends battery charger with item no. 1136-0602-01 which may be ordered by an authorised dealer.

2.You can also allow the engine to charge the battery. In this case it is very important, above all when starting the machine for the first time and when it has not been used for a long time, to allow the engine to run continuously for at least 45 minutes.

Do not short circuit the battery’s terminals. Sparks occur which can result in fire. Do not wear metal jewellery which can come into contact with the battery terminals.

In the event of damage to the battery casing, cover, terminals or interference to the strip covering the valves, the battery should be replaced.

Stiga Park Pro 16 Owner's Manual

If the battery terminals are coated with oxide, they should be cleaned. Clean the battery terminals with a wire brush and grease them.

LUBRICATION

The machine’s articulated steering joint has four grease nipples that should be lubricated with universal grease after every 25 hours of operation (fig. 20).

The battery is a valve-regulated battery with 12 V nominal voltage. The battery is completely maintenance free. You don’t have to check or top up the

Note: The fourth grease nipple is not shown on the picture. It is located on the underside, on the flexible axle’s front bearing.

Comfort-President-Royal:

Lubricate the steering chain with chain spray a couple of times per season.

Pro16-Pro20:

Lubricate the steering chains with chain spray a couple of times per season. If the steering chains are really dirty, dismantle them, wash them and then grease them once more.

Comfort-President-Royal:

The front wheel hub has grease nipples that should be lubricated after every 50 hours of operation (fig. 24).

Apply universal grease to all the plastic bearings a couple of times per season.

Apply a coating of engine oil to the tension arm joints a couple of times each season.

Apply a few drops of engine oil to both ends of the throttle control cables a couple of times a season.

The hydrostatic transmission is filled with oil (10W-40) on delivery from the factory. Unless it is opened (only to be performed by a specialist), and provided no leakage occurs, no topping up with oil should normally be carried out. Transmission oil does not normally need to be changed.

STEERING CABLES

(President - Comfort - Royal)

The steering cables should be adjusted for the first time after the machine has been in operation for 2 - 3 hours, and then after every 25 hours of operation.

Put the machine in the straight-ahead position.

Tension the steering cables by tightening the nuts that are located on the underside of the articulated steering joint (fig. 21). The screws in the ends of the cables should be held firmly during adjustment so that the cables are not twisted. Use an adjustable wrench or similar for this purpose, inserting it in the key handles in the ends of the screws. Tension until all play is removed.

Adjust both the nuts the same amount to ensure that the alignment of the steering wheel is not changed.

Once the adjustment is complete, turn the steering wheel as far as it will go in either direction. Check that the chain does not come into contact with the pulley, and that the cables do not become entangled with the steering pinions.

Do not tension the steering cables too hard. Otherwise the steering will be heavy and wear and tear on the cables will increase.

STEERING CHAINS (Pro16 - Pro20)

The steering chains should be adjusted for the first time after the machine has been in operation for 2 - 3 hours, and then after every 50 hours of operation.

Put the machine in the straight-ahead position.

Tension the steering chains by tightening up the nuts that are located on the underside of the articulated steering joint (fig. 21). Tension until all play is removed.

Adjust both the nuts the same amount to ensure that the alignment of the steering wheel is not changed.

Do not over-tighten the steering chains. This will cause the steering to become heavy and will increase wear on the steering chains.
