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. Location of the controls 1. Ignition lock 7. Parking brake 2.
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 can be fitted with four different cutting units. BioClip Combi Combi - 900 mm/36" - 1120 mm/44" - 1030 mm/41" See ”Maintenance \ Checking the Blades” for identification of the cutting unit. 6017-214 Lift lever for the 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, 40-90 mm (1 9/16" - 3 9/16") 45-95 mm (1 3/4" - 3 3/4") BioClip unit, 6004-013H Seat The seat has a jointed attachment on the front edge and can be tipped forward.

LUBRICATION Check the engine’s oil level Check the oil level in the engine when the Rider stands horizontal with the engine switched off. Fold open the engine cover. Release the dip stick and pull out. Wipe off the oil and insert again. The dip stick must be fully screwed down. Now release the dip stick again and pull out. Check the oil level. The oil level should be between the markings on dip stick. If the level approaches the ADD mark, top up with oil to the FULL mark.
LUBRICATION Change of oil filter Replace oil filter every 200 operating hours. Drain oil first using the plug on the filter base. Remove the old filter using an oil filter tool. Lightly coat rubber gasket with new oil, then install filter by turning it to the right until hand tight. Tighten the filter an additional 1/2 turn. Check that the drain plug is reinstalled before starting the engine. Start engine and check for leakage. 8009-466 Check the transmission’s oil level 1. Remove the transmission cover.
TROUBLE SHOOTING SCHEDULE Problem Procedure Engine will not start. • • • • Fuel tank empty. Spark Plug defective. Spark Plug connection defective. Dirt in carburettor or fuel pipe. Starter does not pull round engine. • • • • • • • Battery flat. Bad contact between cable and battery terminal. Lift lever for cutting unit in wrong position. Main fuse blown. The fuse is placed in front of the battery, under the battery cover. Ignition lock faulty. Gear shift/hydrostat pedal not in neutral.
STORAGE Winter storage At the end of the season the machine should immediately be put in order for storage, also if it is going to stand idle for more than 30 days. Fuel which is left to stand for long periods (30 days or more) can leave tacky deposits which can block the carburettor and interfere with the engine. Fuel stabiliser is an acceptable alternative to avoid tacky deposits during storage. If alkylate petrol (Aspen) is used stabiliser is not necessary since this fuel is stable.
