61 ENGLISHEN 2.4.2 Implement lifter, hydraulic (5:M)(Pro20, Pro23, Pro Svan) The hydraulic implement lifter only works when the engine is running and the clutch pedal and parking brake pedal are not depressed. The imple- ment lifter is controlled using the lever (5:M). The lever has the following four positions: Floating position . Move the lever to its front position, where it locks. The imple- ment is now lowered to its floating posi- tion. In the floating position, the implement always rests against the ground at the same pressure and can follow the con- tours of the ground. Use the floating position when carrying out work. Lowering . The implement lowers re- gardless of its weight. Locking in the transport position . The lever has returned to the neutral position after raising and lowering. The imple- ment is locked in the transport position. Raising. Move the lever to the rear posi- tion until the implement is in the highest position (transport position). Then re- lease the lever to lock in the transport po- sition. 2.4.3 Clutch-parking brake (3:B) Never press the pedal while driving. There is a risk of overheating in the power transmission. The pedal (3:B) has the follow- ing three positions: Released . The clutch is not ac- tivated. The parking brake is not activated. Depressed halfway . Forward drive disengaged. The parking brake is not activated. Fully depressed . Forward drive disengaged. The parking brake is fully activated but not locked. This position is also used as emergency brake. 2.4.4 Inhibitor, pa rking brake (3:A) The inhibitor locks the “clutch-brake” pedal in the depressed position. This func- tion is used to lock the machine on slopes, during transport, etc., when the engine is not running. Locking: 1. Depress the pedal (3:B) fully. 2. Move the inhibitor (3:A) to the right. 3. Release the pedal (3:B). 4. Release the inhibitor (3:A). Unlocking: Press and release the pedal (3:B). 2.4.5 Driving-service brake (3:F) If the machine does not brake as expect- ed when the pedal is released, the left pedal (3:B) should be used as an emer- gency brake. The pedal determines the gearing ratio between the engine and the drive wheels (= the speed). When the pedal is released, the service brake is activated. 1. Press the pedal forward – the machine moves forward. 2. No load on the pedal – the machine is stationary. 3. Press the pedal backward – the machine reverses. 4. Reduce the pressure on the pedal – the machine brakes. There is an adjustment plate on the upper section of the pedal. The adjustment plate can be adjusted to three (3) positions to suit the driver’s foot. 2.4.6 Steering wheel (3:D) The height of the steering wheel is infinitely ad- justable. Undo the adjustment knob (3:E) on the steering column and raise or lower the steering wheel to the desired position. Tighten. Do not adjust the steering wheel during operation. Never turn the steering wheel when the machine is stationary with a lowered implement. There is a risk of abnormal loads on the servo and steering mecha- nisms. 2.4.7 Throttle control (4,5:G) Control for setting the engine’s revs. 1. Full throttle – when the machine is in operation, full throttle should always be used. 2. Idling. 2.4.8 Choke control (4,5:H) A pull-type control to choke the engine when start- ing from cold. 1. Control fully pulled out – choke valve in carburettor closed. For starting cold en- gine. 2. Control pushed in – choke valve open. For starting warm engine and when oper- ating the machine. Never operate the machine with the choke pulled out when the engine is warm.

62 ENGLISHEN 2.4.9 Ignition lock/headlight (4,5:I) The ignition lock is used for starting and stopping the engine. The ignition lock is also the switch for the headlight. Do not leave the machine with the key in position 2 or 3. There is a fire risk, fuel can run into the engine through the carburettor, and there is a risk of the battery being discharged and damaged. Four positions: 1. Stop position – the engine is short- circuited. The key can be removed. 2. Operating position – headlight activat- ed. 3. Operating position – headlight not ac- tivated. 4. Start position – the electric start motor is activated when the key is turned to the spring-loaded start position. Once the en- gine has started, let the key return to oper- ating position 3. Turn the key to position 2 to light the headlight. 2.4.10 Power take-off (4,5:K) The power take-off must never be en- gaged when the front-mounted imple- ment is in transport position. This will destroy the belt transmission. Switch for engaging/disengaging the electromag- netic power take-off for operating front-mounted accessories. Two positions: 1. Press the front part of the switch – the power take-off is engaged. The symbol will light up. 2. Press the rear part of the switch – the power take-off is disengaged. 2.4.11 Hour meter (2:P) Indicates the number of working hours. Only works when the engine is running. 2.4.12 Cutting height adjustment (4,5:J) The machine is equipped with a control for using the cutting deck with electrical cutting height ad- justment. The switch is used to adjust the cutting height in continuously variable positions. The cutting deck is connected to the contact (2:Q). 2.4.13 Rear Rake (4, 5:L) The machine is fitted with a control for electrical adjustment of a rear rake (available as an accesso- ry). The switch is used to raise and lower the rear rake. Cables for connecting the rear rake are found at the rear of the machine, to the left of the upper side of the bumper. 2.4.14 Sand spreader (4, 5:O) The machine has been designed for electrical ad- justment of a sand spreader (accessory). The switch is used to start and stop the spreader. Cables for connecting the sand spreader are at the rear of the machine. 2.4.15 Clutch release lever (6:R) A lever for disengaging the variable transmission. Enables the machine to be moved by hand without the help of the engine. The disengagement lever must never be between the outer and inner positions. This overheats and damages the trans- mission. Two positions: 1. Lever out – transmission en- gaged for normal operation. There is an audible click when the lever locks in the outer posi- tion. 2. Lever in – transmission dis- engaged. The machine can be moved by hand. The machine may not be towed over long distances or at high speeds. The transmission could be dam- aged. 2.4.16 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:S) 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 4.3.14.3.2. 12V

63 ENGLISHEN 2.4.17 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. 2.4.18 Qui ck-release mounting (15: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 (15:G) from both sides. 2. Open the quick connections by depressing their rear sections with your heel. See (15: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. 17. 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 (16:J) and carefully turn a half turn forwards. 2. Install the locking pin (15:G). 3. Carry out the above on the other side.3 AREAS OF USE The machine may only be used using genuine STIGA accessories: The maximum vertical load on the towing hitch must not exceed 100 N. The maximum over-run load on the towing hitch from towed accessories must not exceed 500 N. NOTE! Before using a trailer – contact your insur- ance company. NOTE! This machine is not intended to be driven on public roads. 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 pet- rol. This type of petrol has a composition that is less harmful for people and nature.

64 ENGLISHEN 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 LEVEL On delivery, the crankcase is filled with SAE 10W- 30 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, Pro23: 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. 9-10. 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!

65 ENGLISHEN 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, PRO23, 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. Never use high-pressure water. This can damage shaft seals, electrical compo- nents or hydraulic valves. Never use high-pressure air against the radiator fins. This will damage the fin structure. Clean the machine after each use. The following instructions apply for cleaning: 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 (9-10:W). After cleaning with water, start the machine and any cutting deck to remove the water that may otherwise penetrate bearings and cause damage . 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 Serv- ice 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.

66 ENGLISHEN 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. 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 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. 11-12:Y. 2. Move the clamp up 3-4 cm on the oil drainage hose and pull out the plug. 3.

La puissan- ce dégagée par le moteur est transmise aux roues par un système hydraulique. Le moteur actionne une pompe qui fait circuler de l’huile dans le dis- positif d’entraînement des trains avant et arrière. Les trains avant et arrière sont connectés en série, ce qui signifie que les roues avant et arrières tour- nent obligatoirement à la même vitesse. Pour faciliter les manœuvres, les deux essieux sont équipés d’un différentiel. Les accessoires montés à l’avant sont mus par les courroies d’entraînement. 2.2 DIRECTIONLa machine est articulée. Cela signifie que le châs- sis est divisé en deux sections, avant et arrière, qui pivotent l’une par rapport à l’autre. Grâce au châssis articulé, la machine possède un rayon de braquage très faible qui lui permet de contourner arbres et obstacles. 2.3 DISPOSITIFS DE SÉCURITÉLa machine est équipée d’une sécurité électrique qui interrompt certaines activités susceptibles de provoquer des manœuvres dangereuses. Par exemple Le moteur ne démarre que lorsque l’embrayage est enfoncé. Contrôler le fonctionnement du disposi- tif de sécurité avant chaque utilisation. 2.4 COMMANDES 2.4.1 Dispositif mécanique de levage des accessoires, (3:C) (Pro16) Pour passer de la position de travail à la position de transport : 1. Enfoncer à fond la pédale. 2. Relâcher la pédale progressivement. 2.4.2 Dispositif hydr aulique de levage (5:M) (Pro20, Pro23, Pro Svan) Le dispositif hydraulique de levage ne fonctionne que lorsque le moteur tourne et que l’embrayage et le frein de stationnement ne sont pas engagés. Le dispositif de levage des outils est commandé par le levier (5:M).
