Check that the safety devices work each time before using the machine. • Do not alter the engine’s regulator setting and do not race the engine. The danger of personal injury increases when the engine is run at high revs. • Do not touch engine components which become warm during use. Risk of burn injuries. • Do not leave the driving seat without: a. Disengaging the power take-off and lowering the accessories.

22 ENGLISHEN b. Putting the gear in neutral and activating the parking brake. c. Stopping the engine and removing the key. • Only use accessories that are approved by the machine’s manufacturer. • The machine may not be used without accessories/tools being installed in the machine’s tool mounts. Driving without accessories can have a negative effect on the stability of the machine. • Take care when using grass collectors and other accessories. These can alter the machine’s stability. Particularly on slopes. • Disengage the drive to the accessories, shut off the engine and disconnect the spark plug cable or remove the starter key: a. To remove sticks and rubbish or when the discharge has become clogged. b. To check, clean or service the machine. c. To check whether damage has occurred and to carry out any repairs before starting and using the machine again after a collision with a foreign object. d. To check the machine if it begins to vibrate excessively. (Check immediately). • Disengage the drive to accessories during transport or when the machine is not in use. • Shut off the engine and disconnect the drive to the accessories: a. Before filling with petrol. b. Before removing the grass collector. c. Before adjusting the height setting, assuming this cannot be done from the driver’s position. • Reduce the acceleration when the engine is to be stopped, and if the engine is equipped with a fuel shut-off valve, this should be switched off when the work is finished. • Take care with multiple blade decks as one rotating blade can cause other blades to rotate. • The machine, equipped with original accessories, must not be driven in any direction on slopes with a gradient greater than 10º. • The cutting deck’s original blade(s) may not be replaced with non-original devices intended for e.g. moss scarification. If such devices are used, the guarantee will cease to be valid. There is also a risk of serious injury or damage to people or property. • Take care when unloading and loading the machine onto a trailer or lorry. 2.4 MAINTENANCE AND STORAGE• Tighten all nuts and screws so that the machine is in safe working condition.• At regular intervals check that the cutting deck’s blade screw(s) are properly tightened. • Regularly check the operation of the brakes. It is important to maintain and repair the brakes if necessary. • Never store the machine with petrol in the tank in buildings where the fumes can come into contact with open flames or sparks. • Allow the engine to cool before placing the machine in a store. • To reduce the risk of fire, keep the engine, silencer, battery and petrol tank free from grass, leaves and surplus oil. • Check frequently whether there is any wear or damage to the grass collector. • For the sake of safety, replace worn or damaged parts. • Always use genuine spare parts. Non-genuine spare parts can entail a risk of injury, even if they fit the machine. • Replace damaged warning and instruction stickers. • If there is no mechanical lock for the transport position, the cutting deck must be lowered when parked, stored or when the machine is left unsupervised. • If the petrol tank is to be emptied, this must take place outdoors. • Store the machine so that children cannot get to it. • The battery contains acid. In the event of mechanical damage or overcharging, acid can leak out. • Never overcharge the battery. Overcharging can cause the battery to explode, throwing the acid in all directions. • 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. • Fumes from acid that are inhaled cause damage to mucous membranes and other internal organs. Seek medical assistance if acid fumes have been inhaled. • Acid causes serious damage to tools, clothes and other material. Rinse away spilled acid immediately with water. • 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

23 ENGLISHEN covering the valves, the battery should be replaced. 3 STORAGE Empty the petrol tank. Start the engine and let it run until it stops. Replace the oil while the engine is still warm. Unscrew the spark plug and pour a tablespoonful of oil into the cylinder. Rotate the engine a few turns to that the oil is distributed in the cylinder. Install the spark plug. Clean the entire machine. It is particularly important to clean under the cutting deck. Touch up paint damage to prevent rust. Store the machine indoors in a dry place. Machines with an electric starter: Remove the battery. Store it well charged in a cool place (between 0°C and +15°C). At the correct storage temperature, the battery should be maintenance-charged every four months. The battery acid is extremely corrosive and can cause injuries and damage to skin and clothing. Always use rubber gloves and glasses (goggles) to protect your eyes. Avoid inhaling any acid vapour. Do not incline the battery too much so that the battery acid can run out onto hands or clothing. If this should happen, rinse with plenty of water. 4 SERVICE Authorised service workshops carry out repairs and guarantee service. They use original spare parts.

The rear axle is equipped with a hydrostatic trans- mission with infinitely variable forward and re- verse gear ratios. The rear axle is also equipped with a differential to facilitate turning. Front mounted tools are driven by drive belts. 11.2 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.

26 ENGLISHEN 11.3 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. 11.4 Controls 11.4.1Implement lifter, mechanical (10:C) To switch between working position and transport position: 1. Depress the pedal fully. 2. Release the pedal slowly. 11.4.2Clutch-parking brake (10:B) Never press the pedal while driving. There is a risk of overheating in the power transmission. The pedal (10:B) has the follow- ing three positions: •Released. The clutch is not activated. The park- ing 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. 11.4.3Inhibitor, parking brake (10: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 (10:B) fully. 2. Move the inhibitor (10:A) to the right. 3. Release the pedal (10:B). 4. Release the inhibitor (10:A). Unlocking: Press and release the pedal (10:B).11.4.4 Driving-service brake (10:F) If the machine does not brake as expect- ed when the pedal is released, the left pedal (1:B) should be used as an emer- gency brake. The pedal (10:F) determines the gearing ratio be- tween 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 ma- chine is stationary. 3. Press the pedal backward – the machine reverses. 4. Reduce the pressure on the pedal – the machine brakes. 11.4.5 Throttle control (11: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. 11.4.6 Choke control (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. 11.4.7 Ignition lock (11:I) The ignition lock is used for starting and stopping the engine. 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-cir- cuited. The key can be removed. 2, 3. Operating position

27 ENGLISHEN 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. 11.4.8 Power take-off (4,5:K) The power take-off must never be engaged when the front-mounted implement is in transport position. This will destroy the belt transmission. A lever for engaging and disengaging the power take-off for operating front-mounted accessories. Two positions: 1. Lever in forward position – power take- off disengaged. 2. Lever in backward position - power take-off engaged. 11.4.9 Hour meter (2:P) Indicates the number of working hours. Only works when the engine is running. 11.4.10Clutch release lever A lever for disengaging the variable transmission. 2WD is equipped with a lever, connected to the rear axle. See (6:R). The disengagement lever must never be between the outer and inner positions. This overheats and damages the trans- mission. The levers enable the machine to be moved by hand without the help of the engine. Two positions: 1. Lever in the inner position – transmission engaged for normal operation. 2. Lever in the outer position – transmission disengaged. 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. The machine must not be operated with the forward most lever in the outer po- sition. Risk of damage and oil leakage in the front axle. 11.4.11Seat (8:T) The seat can be folded and adjusted front- rear. The seat can be adjusted as follows: 1. Move the control lever (8:S) upwards. 2. Set the seat to the desired position. 3. Release the control lever (8: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 13.4.2. 11.4.12Engine casing (2: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 (2: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. 12 AREAS OF USE The machine may only be used for the following tasks using the genuine STIGA accessories stated. 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.

28 ENGLISHEN NOTE! Before using a trailer – contact your insur- ance company. NOTE! This machine is not intended to be driven on public roads. 13 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. 13.1 Filling with petrolAlways use lead-free petrol. You must never use 2- stroke petrol mixed with oil. The tank holds 12 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. 13. 13.2 Checking the engine oil levelOn 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. 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. 14. 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. 13.3 Level check, transmission oil 1. Place the machine on a flat surface. 2. Read off the oil level in the reservoir. See fig. 18. The level should be level with the line. 3. If necessary, top up with more oil. 13.4 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. 13.4.1 General safety check 13.4.2 Electrical safety check The operation of the safety system should always be checked every time before use.

29 ENGLISHEN 13.5 Start1. Open the fuel cock. See 16. 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. 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 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. 13.6 Operating tipsAlways check that there is the correct volume of oil in the engine. This is particularly important when operating on slopes. See “13.2”. 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. 13.7 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. 13.8 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 (14:W). 14 MAINTENANCE 14.1 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 “13.4” 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. 14.2 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.

30 ENGLISHEN 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. 14.3 Tyre pressureAdjust the air pressure in the tyres as follows: Front: 0.6 bar (9 psi). Rear: 0.4 bar (6 psi). 14.4 Changing engine oilThis section contains tables covering the different engines that are included in STIGA’s range. To fa- cilitate reading, mark the data that applies to the relevant machine/engine. 14.4.1Change 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. 14.4.2Engine 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. 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. Remove the dipstick and fill with new oil. Oil quantity: 0,9 l 7. After filling up the oil, start the engine and idle for 30 seconds. 8. Check to see if there is any oil leakage. 9. Stop the engine. Wait for 30 seconds and then check the oil level in accordance with “13.2”. 14.5 Fuel filterReplace the fuel filter after 1,500 hours of opera- tion. Check for fuel leaks once the new filter has been installed. 14.6 Belt transmissionsAfter 5 hours of operation, check that all the belts are intact and undamaged. 14.7 SteeringThe steering must be checked/adjusted after 5 hours of operation and thereafter after 100 hours of operation. 14.7.1 Checks Briefly turn the steering wheel back and forth. There must be no mechanical clearance in the steering chains. 14.7.2 Adjustment Adjust the steering chains if required as follows: 1. Put the machine in the straight-ahead position. 2. Adjust the steering chains with the two nuts, lo- cated under the central point. See fig. 20. 3. Adjust both nuts by the same amount until there is no clearance. 4. Test drive the machine straight forwards and check that the steering wheel is not off centre. 5. If the steering wheel is off centre, undo one nut and tighten the other. Do not over-tighten the steering chains. This will cause the steering to become heavy and will in- crease wear on the steering chains. 14.8 Battery 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.
