SAFETY INSTRUCTIONS Safety instructions These instructions are for your safety. Read them carefully. WARNING! The inserted symbol means that important safety instructions need to be observed. It applies to your safety. General use • Read all the instructions in this operator’s manual and on the machine before you start it. Ensure you understand them and then observe them. • Learn how to use the machine and its controls safely and learn to how to stop quickly. Also learn to recognize the safety decals.
SAFETY INSTRUCTIONS • Take care when rounding a fixed object, so that the blades do not hit it. Never run the machine over foreign objects. • Only use the machine in daylight or in other well-lit conditions. Keep the machine at a safe distance from holes or other irregularities in the ground. Pay attention to other possible risks. • Never use the machine if you are tired, if you have consumed alcohol, or if you are taking other drugs or medication that can affect your vision, judgment or co-ordination.
SAFETY INSTRUCTIONS Driving on slopes Driving on slopes is one of the operations where the risk of the driver losing control of the machine or of it overturning is the greatest; this can result in serious injury or death. All slopes demand extra care. If you cannot reverse up a slope or if you feel unsure, do not mow it. Proceed as follows: • Remove obstacles such as stones, branches, etc. • Mow upwards and downwards, not sideways. • Do not use the machine on ground that slopes more than 15°.
SAFETY INSTRUCTIONS Children • Serious accidents may occur if you fail to be on your guard for children in the vicinity of the machine. Children are often attracted to the machine and mowing. Never assume that children will remain where you last saw them. • Keep children away from the area to be mowed and under close supervision by another adult. • Keep an eye out and shut off the machine if children enter the work area.
SAFETY INSTRUCTIONS • If leaks arise in the fuel system, the engine must not be started until the problem has been resolved. • Store the machine and fuel in such a way that there is no risk that leaking fuel or fumes can cause any damage. • Check the fuel level before each use and leave space for the fuel to expand, because the heat from the engine and the sun may otherwise cause the fuel to expand and overflow. • Avoid overfilling.
SAFETY INSTRUCTIONS • Never use the machine indoors or in spaces lacking proper ventilation. Exhaust fumes contain carbon monoxide, an odourless, poisonous and highly dangerous gas. • Stop and inspect the equipment if you run over or into anything. If necessary, make repairs before starting. • Never make adjustments with the engine running. • The machine is tested and approved only with the equipment originally provided or recommended by the manufacturer. • The blades are sharp and can cause cuts.
PRESENTATION Presentation Congratulations on your choice of a top quality product which you will enjoy for many years. These instructions describe the Rider 155. This rider mower is equipped with a 15.5 horsepower Kohler engine. The power transmission from the engine is handled by a hydrostatic gearbox, which allows variable variation of the speed by using the pedals. There is one pedal for driving forwards and one pedal for reversing. 6017-213 8009-114 Location of the controls 1. Ignition lock 7.
PRESENTATION Throttle and Choke lever The engine speed is adjusted with the throttle control, and thereby also the rotation speed of the blades. The control is also used to activate the choke function. When the choke is used the engine receives a richer mixture of fuel and air, which simplifies cold start. 6004-004H Speed limiter 2 1 The speed of the machine is steplessly regulated with two pedals. Pedal (1) is used to drive forwards and pedal (2) for reversing.
PRESENTATION Cutting unit The Rider 155 is equipped with cutting unit. • Combi - 1030 mm/41" The combi deck functions as a mulching deck when a BioClip plug is mounted. Otherwise, the deck will function as a rear ejection deck. 6017-214 Lift lever for cutting unit The lift lever is used to set the cutting unit in transport or cutting position. If the lever is pulled back the unit will lift up and the blades will automatically stop rotating (transport position).
PRESENTATION Lever for adjustment of cutting height With this lever the cutting height can be adjusted to 9 different positions. Combi 103 unit, 45-95 mm (1 3/4" - 3 3/4") 6004-013H Seat The seat has a jointed attachment on the front edge and can be tipped forward. The seat can also be adjusted lengthways. Release the knobs under the seat and adjust it forwards or backwards to the required position. Lock the setting with the knobs.
DRIVING 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. Impaired cooling of the engine. Risk of major engine damage. 8009-431 Before starting • Read the safety instructions and information on the location and function of the controls before starting. • Conduct daily maintenance before starting (see “Maintenance Schedule”). 6007-001H Starting the engine 2 1.
