PRESENTATION Throttle Control The throttle is used to control the speed of the engine and thereby also the rotation speed of the blades. In order to increase or decrease the engine speed, the control is moved forwards or backwards respectively. Avoid idling the engine for long periods, as there is a risk of carbon build-up on the spark plugs. 8009-533 Choke Lever The choke lever is used for cold starts in order to provide the engine with a richer fuel mixture.
PRESENTATION Cutting Unit Rider ProFlex 21 AWD can be equipped with cutting units of the types Combi 112 with a 112 cm cutting width and Combi 122 with a 122 cm cutting width. The Combi unit functions as a BioClip unit when a BioClip plug is fitted, but can be set to rear ejection by removing the BioClip plug. The unit’s BioClip function finely chops the grass several times before returning it to the lawn as fertiliser. The rear ejector ejects the clippings behind the unit without finely chopping them.
PRESENTATION Cutting Height Adjustment Lever Using the cutting height lever, the cutting height can be adjusted between seven different positions. It is important that the air pressure in both front wheels is equal, 60 kPa / 0.6 bar / 9 PSI, to produce an even cutting height. 8009-557 Lever for Hydraulic Lift of Attachments The lifting lever is used to put the cutting unit in either the transport or mowing position when hydraulic pressure is available.
PRESENTATION Mechanical Lifting Lever for Cutting Unit The lever is used as a backup lever to put the cutting unit in either the transport or mowing position when hydraulic pressure is unavailable. It can also be used to mechanically secure the cutting unit in the transport position. The lever must be used when starting the engine, if the engine stopped with the unit in the mowing position, in order to raise the unit so that the start lock circuit is disengaged.
PRESENTATION Parking Brake The parking brake is activated as follows: 1. Press down the parking brake pedal. 2. Completely depress the lock button on the steering servo housing. 3. Release the parking brake pedal while keeping the button pressed in. The parking brake lock is automatically disengaged when the brake pedal is pressed down. 8009-328 Seat The seat has a hinged mounting on the front edge and can be folded forwards. The seat can also be adjusted lengthways.
PRESENTATION Clutch Control AWD models have separate clutch controls for forward and rear axles. The clutch controls are used to move the Rider when the engine is not running. Pull the controls to the end positions, do not use an intermediate position. Rear Axle The control is positioned on the inside of the left rear wheel. • Forward control (pulled out), drive system disengaged. • Rear control (pushed in), drive system engaged.
DRIVING Mowing Tips WARNING! Clear the lawn of stones and other objects that can be thrown out by the blades. • Localise and mark rocks and other fixed objects in order to avoid collisions. • Begin with a high cutting height and reduce it until the desired mowing result is attained. • The mowing result will be best with a high engine speed (the blades rotate rapidly) and low speed (the Rider moves slowly).
DRIVING Clutch Control The clutch controls must be pulled out in order for the Rider to be moved when the engine is shutoff. Should you attempt to drive the machine with the clutch controls pulled out it will not move. The drive on the axle is disengaged when one of the controls is pulled out. Pull out or press in the controls fully. Do not use an intermediate position.
DRIVING Running IMPORTANT INFORMATION The air intake grille in the engine cover behind the driver's seat must not be blocked by, for example, clothing, leaves, grass or dirt.

TROUBLE SHOOTING Trouble Shooting Guide Problem Cause The engine will not start.
TROUBLE SHOOTING Problem Cause Engine overheating • Engine overloaded • Air intake or cooling fins clogged • Damaged fan • Too little or no oil in the engine • Faulty pre-ignition • Faulty spark plugs • One or more battery cells faulty • Poor contact on the battery terminal cable connectors • Faulty generator or regulator • Insufficient battery maintenance • The blades are loose • The engine is loose • Pulley loose or bearings worn • One or more blades imbalanced, caused by dam
STORAGE Storage Winter Storage At the end of the mowing season, the Rider should be readied for storage, likewise if it will not be in use for more than 30 days. Fuel allowed to stand for long periods of time (30 days or more) can leave sticky residues that can clog the carburettor and disrupt engine function. Fuel stabilizers are an acceptable option as regards sticky residues during storage. If alkylate petrol is used, stabilisers are unnecessary because this fuel is stable.
STORAGE 5. Remove the spark plugs and pour about a tablespoon of engine oil into each cylinder. Turn over the engine so that the oil is evenly distributed and then refit the spark plugs. 6. Lubricate all grease nipples, joints, and shafts. 7. Remove the battery. Clean, charge, and store in a cool place. 8. Store the Rider in a clean, dry place and cover it for extra protection.
