Serious personal injury and/or damage to property may result if the instructions are not followed carefully. You must read these instructions for use and the accompanying pamphlet “SAFETY INSTRUCTIONS” carefully, before starting up the machine. 1.1 SYMBOLS The following symbols appear on the machine. They are there to remind you of the care and attention required during use and maintenance. This is what the symbols mean: Warning! Read the instruction manual and the safety manual before using the machine. Warning! Watch out for discarded objects. Keep onlookers away. Warning! Always wear hearing protectors. Warning! This machine is not designed to be driven on public roads. Warning! The machine, equipped with original accessories, must not be driven in any direction on slopes with a gradient greater than 10º. Warning! Risk of crushing injuries. Keep hands and feet well away from the articulated steering joint. Warning! Risk of burn injuries. Do not touch the silencer/catalytic converter. 2 DESCRIPTION 2.1 Drive The machine has 4-wheel drive. The power from the engine to the drive wheels is transferred hydraulically. 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 series, 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 Steering The 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 system The machine is equipped with an electrical safety system. The safety system interrupts certain activities that can entail a danger of incorrect manoeuvres. 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 1.2 References 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. 1.2.1 Figures The figures in these instructions for use are numbered 1, 2, 3, etc. Components shown in the figures are marked A, B, C, etc. A reference to component C in figure 2 is written “2:C”. 1.2.2 Headings The headings in these instructions for use are numbered in accordance with the following example: “1.3.1 General safety check” is a subheading to “1.3 Safety checks” and is included under this heading. When referring to headings, only the number of the heading is normally specified. E.g. “See 1.3.1”. 2.4.2 Implement lifter, hydraulic (5:M) (Pro20, Pro25, 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 implement 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 implement is now lowered to its floating position. In the floating position, the implement always rests against the ground at the same pressure and can follow the contours of the ground. Use the floating position when carrying out work. 64 EN ENGLISH Lowering. The implement lowers regardless of its weight. Locking in the transport position. The lever has returned to the neutral position after raising and lowering. The implement is locked in the transport position. Raising. Move the lever to the rear position until the implement is in the highest position (transport position). Then release the lever to lock in the transport position. 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 following three positions: • Released. The clutch is not activated. The parking brake is not activated. • Depressed halfway. Forward drive disengaged.

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 unless the engine casing is closed and locked. Risk of burns and crushing injuries. 2.4.19Quick-release mounting (34: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 positions: • Normal position with fully tensioned belt. • 4 cm behind the normal position with slackened belt so that the deck gets closer to the base machine. 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 (34:G) from both sides. 2. Open the quick connections by depressing their rear sections with your heel. See (34: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. 36. 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.

Risk of burns and crushing injuries. 4.1 4.2 Checking the engine oil level On delivery, the crankcase is filled with SAE 10W40 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 screwing 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. 9-11. 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. Safety checks Check that the results of the safety checks below are achieved when testing the machine in question. The safety checks must always be carried 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. Filling with petrol Always use lead-free petrol. You must never use 2stroke 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 topping 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.

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 machine work under load immediately, but let the engine run for a few minutes first. This will allow the oil to warm up. When the machine is in operation, full throttle should always be used. 4.5 Power assisted steering (Pro20, Pro25, Pro Svan) Power assisted steering means that power from the machine’s hydraulic system is supplied to the steering wheel movements. This makes the machine very easy to steer when the engine is operating at working revs (full throttle). The servo effect is reduced as the engine speed drops. 4.6 Operating tips Always 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 driving 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. 4.7 Stop Disengage 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 important if the machine is to be transported on a trailer for example. If the machine is left unattended, remove the spark plug cable(s) and remove the ignition 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. 4.8 Cleaning To reduce the risk of fire, keep the engine, 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 compressed air. • Clean the engine’s cooling air intake (9-11:W). • Only Pro25: Clean the oil cooler (12:X). 69 EN ENGLISH 5 MAINTENANCE 5.1 Service programme 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 programme should be followed.
