61 ENGLISHEN 2.4.2 Implement lifter, hydraulic (4:M) (4WD) 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 (4: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 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. 2.4.4 Inhibitor, parking 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. The parking brake must always be re- leased during operation.Locking: 1.

64 ENGLISHEN 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 RefuellingOnly use diesel which satisfies the minimum re- quirements of the following specifications: EN 590 BS 2869 A1 / A2 ASTM D 975 - 1D / 2D The engine must not be run on rape die- sel (RME). Contact the engine supplier for additional information. 1. Open the engine casing. 2. Open the fuel cap (9:X). Filling fuel above the “Max” level in fig. 9 results in fuel leakage and risk of fire. 3. Fill with diesel to the “Max” level in fig. 9. If filled above this level the fuel will leak out be- cause it expands when heated. 4. Close the fuel cap. Use winter fuel or add kerosene in ambient tem- peratures below 0°C. See the table below: Diesel is highly flammable. Always store fuel in containers that are made especially for this purpose. Only fill or top up with fuel outdoors, and never smoke when filling or top- ping up. Fill with fuel before starting the engine. Never remove the fuel cap or fill with fuel while the engine is running or still warm. 4.2 BleedingThe engine’s fuel system must be bled in the fol- lowing instances: • If the fuel tank has been run dry and air has been drawn into the fuel system. • After replacing the filter. Bleed as follows: 1. Fill the tank with fuel. 2. Pump using the hand pump (10:Y) until all air has been pumped out. 4.3 Level check, engine oil On delivery, the crankcase is filled with SAE 10W- 40 oil. Always check the oil level before use to ensure it is correct. The machine should be standing on level ground. Check the oil level as follows: 1. Wipe around the dipstick. 2. Unscrew and pull the dipstick up. 3. Wipe the dipstick. 4. Slide the dipstick down completely and pull up again. 5. Read off the oil level. The oil level should be at the “Max” mark as illustrated in fig. 11. If the oil level is below the “Max” mark in fig. 11, fill with oil as follows: 1. Unscrew the oil filler cap (11:C). 2. Fill with the necessary amount of oil. Applica- ble oil types, see “5.4”. 3. Check the level as above. 4. When the level is correct, reinstall the oil filler cap and tighten. The oil level must never exceed the “Max” mark as illustrated in fig. 11. This can cause the engine to overheat. Drain the oil to the correct level if the oil level exceeds the “Max” mark. 4.4 Level check, transmission oil See 5.8.1. 4.5 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. Lowest ambi- ent tempera- ture at start °CProportion of kerosene Summer fuel Winter fuel 0 to -10 20% - -10 to -15 30% - -15 to -20 50% 20% -20 to -30 - 50%

65 ENGLISHEN 4.5.1 General safety check 4.5.2 Electrical safety check The operation of the safety system should always be checked every time before use. 4.6 Start1. Do not keep your foot on the drive pedal. 2. Put the throttle control at full throttle. 3. Depress the brake pedal fully. 4. Turn the ignition key and start the engine. The engine does not need to be preheated. 5. 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 in use, always operate the engine at full throttle. 4.7 Power assisted steering (4WD)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. 4.8 Operating tipsAlways check that there is the correct volume of oil in the engine. This is particularly important when operating on slopes. See 4.3. 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. 4.9 StopDisengage the power take-off. Apply the parking brake. If the machine is left unattended, re- move the ignition key. The engine may be very warm immedi- ately after it is shut off. Do not touch the cylinder or cooling fins.

66 ENGLISHEN 4.10 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 (10:W). 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 motor by always stopping the motor and disconnecting the negative cable from the battery. 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 oilThe engine oil must be changed for the first time after 25 hours of operation and then every 250 hours of operation. Use the following oil specifications: ACEA-B2-E2 or API-CF-CG or SHPD. Select the oil grade according to the table below. Use oil without any additives. Do not overfill with 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. So allow the engine to cool a few minutes before draining the oil. 1. Push the drain hose down so that it comes out under the engine. See fig. 12 2. Tighten the clamp on the oil drain hose. Use a polygrip or similar. 3. Move the clamp 3-4 cm up the oil drain hose and pull out the plug. 4. Collect the oil in a container. NOTE! Do not spill any oil on the drive belts. 5. Dispose of the oil according to local regula- tions. 6. Install the oil drain plug and slide the clamp back so that it clamps over the plug. 7. To clean the oil filter, see 5.4.1 below before continuing. 8. Remove the filler cap (11:C) and fill with oil. The engine has a capacity of around 1.7 litres. 9. After filling the oil, start the engine and run at idle speed for 30 seconds. 10.Check to see if there is any oil leakage. 11.Stop the engine. Wait for 30 seconds and then check the oil level. See 4.3. Top up the oil if necessary. Ambient temperature Oil grade -24°C - +45°C. 10W/40 -30°C - +45°C. 5W/40

67 ENGLISHEN 5.4.1 Oil filter The oil filter must be cleaned after 1000 hours of operation and when changing the oil. First drain the engine oil and install the oil drain plug as above. Then clean the oil filter as follows: 1. Clean the area around the filter (13:A) 2. Slacken off the screw (13:B) 5 turns. 3. Pull out the oil filter.

Continue with point 7 according to “5.4 Chang- ing engine oil” above. 5.5 Engine screwsAll screwed joints on the engine must be check- tightened after 25 hours of operation and then ev- ery 250 hours of operation. Exceptions: • The cylinder head screws must not be touched. • The fuel injection system’s adjustment screws, as illustrated in fig. 15, must not be touched. 5.6 Fuel filterThe fuel filter (10:E) must be replaced after every 500 hours of operation. After replacing, the fuel system must be bled. See “4.2”. Check that there is no fuel leakage once the new filter has been installed. 5.7 Cleaning the fuel tankDuring temperature changes water from the air will condense in the fuel tank. The amount of wa- ter that condenses increases during large tempera- ture changes and at high humidity. The water drops and settles at the bottom of the fuel tank. Condensation should be drained from the fuel tank as necessary and at least once a year. The engine must be cold when the con- densation id drained, otherwise there is a risk of fire. Smoking, fires, sparks and other heat sources are prohibited in the proximity when the condensation is drained. There is a fire risk. Drain the condensation as follows:1. Detach the drain hose from the its mounting un- der the rear bumper. See fig. 16. 2. Turn the drain cock (16:F) in its mounting to fa- cilitate opening. 3. Insert the drain hose into a suitable container. 4. Open the drain cock and drain until all the water has run out. 5. Close the drain cock and reset the cock and hose in reverse order. 6. Dispose of the drained fluid according to local regulations. 5.8 Transmission, oil (4WD)The oil in the hydraulic power transmission must be checked/adjusted and changed at the intervals given in the table below.

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. 5.11.4 Cleaning If the battery terminals are coated with oxide, they should be cleaned. Clean the battery terminals with a wire brush and lubricate them with terminal grease. 5.12 Air filter, engineA damaged air filter allows contaminat- ed air into the engine. This will cause se- rious damage to the engine. The air filter must be cleaned after every 50 hours of operation. The oil filter must be replaced as nec- essary, or after every 500 hours of operation. NOTE! Clean/replace the filter more often if the machine operates in dusty conditions. Remove/install the air filters as follows. 1. Disconnect the splash guard (23:G) by remov- ing the nuts (23:K). 2. Clean carefully around the air filter housing. 3. Disconnect the air filter housing by slackening off the wing nut (23:H). 4. Remove the filter (24:I) by slackening off the ridged nut (24:J).Never direct the flow of compressed air towards the body. The penetration of air into the blood stream can be fatal. 5. Clean off any dry dirt on the filter by blowing compressed air in and out of the filter. The pres- sure must not exceed 5 bar. Check for cracks or other damage after clean- ing. This can be visually checked against a light source. Check that the filter’s mating surfaces are free of faults. If the filter is damaged, it must be replaced. If the filter is contaminated by moisture/oily dirt, it must be replaced. 6. Assemble in reverse order. Do not use compressed air or petroleum based sol- vents such as kerosene to clean the paper filter in- sert. This will damage the filter. 5.13 Air intakeSee 10:W. The engine is air-cooled. A blocked cooling system can damage the engine. Clean the engine’s air intake after 50 hours of operation.
