EN 21 HOW TO USE THE MACHINE 5.3 DIRECTIONS BEFORE STARTING THE WORK Before starting work, it is necessary to carry out several checks and operations to ensure that the work gives the best results and is done in maximum safety 5.3.1 S EAT ADJUSTMENT To change the seat position, loosen the four fixing bolts (1) and slide it along the bracket slots. Once you have found the position, tighten the four screws (1). 5.3.2 T YRE PRESSURE Having the correct tyre pressure is the main condition for ensuring that the cut- ting deck is horizontal and thus mows evenly. Unscrew the valve caps and connect a compressed air line with a gauge to the valves. The pressures are: FRONT 1.5 bar REAR 1.2 bar 5.3.3 F ILLING WITH OIL AND FUEL The type of oil and fuel to use is given in the engine manual. With the engine stopped, check its oil level: according to the exact methodsNOTE 11
described in the engine manual, this must be between the MIN and MAX marks on the dipstick. Refuel using a funnel, but do not completely fill the tank. The tanks capacity is about 5.5 litres. Refuelling should be carried out in an open or well venti- lated area with engine stopped. Always remember that petrol fumes are inflammable. DO NOT TAKE A NAKED FLAME TO THE TANK’S OPENING IN ORDER TO SEE THE TANK’S CONTENTS AND DO NOT SMOKE WHEN REFUELLING. Do not drip petrol onto the plastic parts to avoid ruining them. In the event of accidental leaks, rinse immediately with water. 5.3.4 F ITTING THE PROTECTION AT THE EXIT(GRASS-CATCHER OR STONE-GUARD) Never use the machine without having fitted the exit protection! Hook the grass-catcher (1) onto the brackets (2) and centre it up with the rear plate, so that the two reference marks (3) coincide. Centering is ensured by using the right bracket as lateral support. Make sure that the lower tube of the opening of the grass-catcher clicks onto the pawl (4). !WARNING! IMPORTANT !DANGER!

EN 23 HOW TO USE THE MACHINE If you would like to mow without using the grass-catcher, an optional stone-guard kit (☛ 8.2) is available. This has to be attached to the rear plate as indicated in the relevant instruc- tions. 5.3.5 C HECKING THE EFFECTIVENESS OF THE SAFETY DEVICES Check that the safety systems are working properly by simulating the various sit- uations of usage shown in the table (☛5.2) and making sure that the correct result is achieved for each situation. 5.3.6 C HECKING THE BRAKING SYSTEM Make sure that the machine’s breaking capacity is suited to the conditions of use. Do not start mowing if you have any doubts on the brake efficiency. If doubts on its efficiency persist, consult a Licensed Service Centre. 5.3.7 C HECKING THE BLADES Check that the blades are sharpened properly and firmly fixed to their hubs. – A badly sharpened blade pulls at the grass and makes the lawn turn yellow. – A loose blade causes unusual vibrations and can be dangerous. Wear strong gloves when handling the blades. !WARNING!
5.4 USING THE MACHINE 5.4.1 S TARTING All starting operations have to be effected in an open or well ventilated area! ALWAYS REMEMBER THAT EXHAUST GASES ARE TOXIC! To start the engine: – open the fuel stopcock (1) ( if fitted); – put the transmission into neutral («N») (☛4.22 or 4.32); – disengage the blades (☛4.7); – engage the parking brake on sloping ground; – when starting from cold, move the accelerator lever to the «CHOKE» position shown on the label; – if the engine is already warm, just put the lever between «SLOW» and «FAST»; – put in the key and turn to «ON» to make electrical contact, then turn to «START» to start the engine; – release the key once the engine has started. When the engine has started, put the accelerator in the «SLOW» position. The choke must be closed as soon as the engine is running smoothly. Using it when the engine is already warm can foul the spark plugs and cause the engine to run erratically. The choke must be closed as soon as the engine is running smoothly. Using it when the engine is already warm can foul the spark plugs and cause the engine to run erratically. Turn the key to the «OFF» position, wait for a few seconds and then repeat the operation. If the malfunction continues, refer to chapter «7» of this manual and to the engine manual. Always bear in mind that the safety devices prevent the IMPORTANT NOTE IMPORTANT ➤ !DANGER!

EN 25 HOW TO USE THE MACHINE engine from starting if safety requirements have not been met (☛5.2). In these cases, once the situation has been corrected, the key must first be turned back to «OFF» before the engine can be restarted. 5.4.2 S TARTING AND MOVING WITHOUT MOWING This machine has not been approved for use on public roads. It has to be used (as indicated by the highway code) in private areas closed to traffic. When moving the machine, the blades must be disengaged and the cutting deck put at its highest position (position «7»). For mechanical drive models: Put the accelerator control between the «SLOW» and «FAST» positions, and the gear change lever in the 1st speed position (☛4.22). Keep the pedal pressed down and disengage the parking brake. Slowly release the pedal which will turn from «brake» to «clutch», thus operating the rear wheels (☛4.21). The pedal has to be released gradually as a sudden engagement may cause tipping up and loss of control of the vehicle. Gradually reach the desired operating speed using the accelerator and gear lever. To change the gear speed the clutch must be used pushing the pedal half way down (☛4.21). For hydrostatic drive models: When moving the machine from one area to another, put the accelerator lever in a midway position between «SLOW» and «FAST». Disengage the parking brake and release the brake pedal (☛4.31). Press the drive pedal (☛4.32) in direction »F» and reach the required speed by progressively increasing pressure on the pedal and moving the accelerator appropriately. ➤ !WARNING! ➤ NOTE !WARNING!
EN 26HOW TO USE THE MACHINE Drive must be engaged in the way already described ( ☛4.32) to prevent sudden engagement from causing tipping up and loss of control of the vehicle, particularly on slopes. 5.4.3 B RAKING First, reduce the machine’s speed by reducing the engine’s r.p.m. and then push the brake pedal (☛4.21 or 4.31) to further reduce the speed until the machine stops. For hydrostatic drive models: The machine already slows down considerably by just releasing the drive pedal. 5.4.4 R EVERSE Reverse must be engaged ONLY when the machine is stopped. For mechanical drive models: Push down the pedal until the machine stops and then go into reverse by moving the lever sideways and putting it into position «R» (☛4.22). Gradually release the pedal to engage the clutch and then begin moving in reverse. For hydrostatic drive models: When the machine is stopped, start the reverse movement by pressing the drive pedal in the «R» direction (☛4.32). 5.4.5 G RASS CUTTING To start cutting: – put the accelerator into the «FAST» position; – bring the cutting deck to the highest position; – engage the blades (☛4.9); ➤ ➤ NOTE ➤ !WARNING!
EN 27 HOW TO USE THE MACHINE – start moving forwards onto the grass area very gradually and with particular caution, as already described; – adjust the forward speed and the cutting height (☛4.8) according to the lawn condition (height, density and dampness of the grass). On flat ground, these general conditions can be followed: High and dense grass - wet lawn 2 km/h Average condition grass 3,5 ... 5,5 km/h Low grass - dry lawn over 5,5 km/h For hydrostatic drive models: The speed is controlled in a gradual and progressive way by the pressure on the drive pedal. When cutting on sloping ground, the forward speed must be reduced to ensure safe conditions ( ☛ 1.2 - 5.5). In any case, the speed should always be lowered if you note a reduction in engine speed, since a forward speed that is too fast compared to the amount of grass being cut will never mow the grass well. Disengage the blades and put the cutting deck in the highest position whenever you need to get past an obstacle. 5.4.6 E MPTYING THE GRASS-CATCHER This operation can only be done with the blades disen- gaged, otherwise the engine stops. Do not let the grass-catcher become too full as this may block the collector channel. When the grass-catcher is full there is an audible warning. At this point: – lower the engine speed; – shift into neutral (N) (☛4.22 – mechanical models or 4.32 - hydrostatic mod- els) and stop forward movement; – disengage the blades (☛4.7) and the audible signal will stop;NOTE !WARNING! ➤
EN 28HOW TO USE THE MACHINE – engage the parking brake on slopes; – pull out the lever (1) and tip up the grass- catcher to empty it; – close up the grass-catcher so that it hooks onto the pawl (2). At times the audible warning may be heard at the moment of engaging the blade even when the grass- catcher has been emptied. This is due to grass-cuttings left on the sensor (3) of the micro-switch. To stop the signal, disengage the blade and then immediately engage it again. Always keep the sensor (3) free of grass-cut- tings. 5.4.7 U NBLOCKING THE COLLECTOR CHANNEL Cutting very tall or wet grass, particularly at too high speed, can cause the col- lector channel to become blocked. Should this happen, it will be necessary to: – stop forward movement immediately, disengage the blades and stop the engine; – take off the grass-catcher or stone-guard; – remove the accumulated cuttings, reaching them from the exit of the collector channel. This job must only be performed with the engine turned off. 5.4.8 E ND OF MOWING When you have finished mowing, disengage the blades, lower the engine speed and ride the machine with the cutting deck in the highest position. !WARNING! NOTE 1 2 3
EN 29 HOW TO USE THE MACHINE 5.4.9 END OF WORK Stop the machine, put the accelerator lever in the «SLOW» position and turn off the engine by putting the key into the «OFF» position. When the engine is stopped, close the fuel stopcock (1) ( if fitted). To avoid backfire, put the accelerator in the «SLOW» position for 20 seconds before stopping the engine. Always take out the ignition key if leaving the machine unattended! To keep the battery charged, do not leave the key in the «ON» position when the engine is not running. 5.4.10 C LEANING AND STORAGE After each mowing, clean the outside of the machine, empty the grass-catcher and shake it to remove residual grass and earth. Always empty the grass-catcher and do not leave con- tainers full of cut grass inside a room. Clean the plastic parts of the body with a damp sponge using water and deter- gent, taking care not to wet the engine, the electrical parts or the electronic card located under the dashboard. Never use hose-nozzles or harsh detergents for cleaning the body and engine! For washing the inside of the cutting deck and the collector channel the machine must be on firm ground with: – the grass-catcher or stone-guard fitted; – the operator seated; – the engine running; – the transmission in neutral; – the blades engaged.
