Safety Instructions Chapter 3: Safety Instructions These instructions are for your safety. Read them carefully. General Use • Read all instructions in this operator’s manual and on the machine before starting it. Ensure you understand them and then observe them. • Learn how to use the machine and its controls safely and learn how to stop quickly. Also learn to recognise the safety decals. • If you get into a situation where you feel unsure about how to progress, stop and seek expert advice.
Safety Instructions • Shut down the blades when not mowing. The blades must only be running when the cutting unit is lowered and active when used for mowing. • Be careful when rounding fixed objects, so that the blades do not hit them. Never run the machine over foreign objects. • Never drive close to objects or other machines. Remember that “Brake pedal reflex” from driving a car has the opposite effect if you press on the forward pedal.
Safety Instructions • Never use the machine when barefoot. Always wear protective shoes or protective boots, preferably with steel toes. • Make sure that you have first aid equipment close at hand when using the machine. 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.
Safety Instructions Children • Serious accidents may occur if you fail to be on guard for children in the vicinity of the machine. Children are often attracted to the machine and mowing. Never assume that children will stay put where you last saw them. • Keep children away from the mowing area and under close supervision by another adult. • Keep an eye out and shut off the machine if children enter the work area.
Safety Instructions WARNING: The engine, exhaust system, cooling system and hydraulic system components become extremely hot during operation. Risk of burn injuries if touched. Wear protective gloves • 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 of leaking fuel or fuel vapour leading to damages.
Safety Instructions flammable liquids are stored in an open container. Do not work on the starter motor circuit in the vicinity of spilt fuel. Disconnect the battery's power connection cable (usually the black negative cable) first and connect it last. Exercise care with tools so that short circuiting does not occur. Do not short circuit across the starter relay's connections to run the starter motor. • Be especially careful when handling battery acid. Acid on the skin can cause serious corrosive injuries.
Safety Instructions • Reduce the risk of fire by removing grass, leaves and other debris that may have fastened in the machine. Allow the machine to cool before putting it in storage. • Do not turn over the engine by hand without preventing the engine from starting, which can be done in different ways: a. Remove the glow plug, no compression the engine can therefore be easily turned over. b. Loosen a pressure pipe connection on each jet pipe a 1/2 turn. c.
Safety Instructions hand in for destruction. Remember to follow local regulations. Generally you can deposit waste oil at workshops or petrol stations that handle waste oil. • Replaced oil and fuel filters are environmental hazardous waste, handle them as waste oil. • Do not spill fuel when refuelling. One litre of diesel fuel can, according to the Swedish Rescue Services Agency, destroy up to one million litres of drinking water. Spilt fuel is a fire risk.

During glow plug heating, light (43) on the indicator panel comes on. Non-locking to position ON. Turning again within 2 seconds gives starting without glow plug heating.
Presentation 30. Weight transfer Weight transfer is activated using this switch, transfers a proportion of the unit’s weight to the machine. This causes greater ground pressure on the machine’s front wheels and lower ground pressure on the unit’s pivot wheels. It is recommended to use weight transfer when lawn mowing and sweeping. When snow clearing or changing tools, the function should be off so that the lifting arms can be lowered.
Presentation 36. Chronometer The chronometer shows how many hours the engine has been running. Any time when the engine is not running but the ignition is switched on is not registered. The last digit shows tenths of an hour (6 minutes). 40-51.
Presentation Rops The bow is foldable. Pull out the pins and fold the bow backwards. x2 If the bow is used unfolded, safety belt must be used . If the bow is used folded, safety belt should NOT be used.
Presentation Cooling system IMPORTANT INFORMATION: Coolant must be a mixture of 50 % antifreeze fluid and 50 % soft water. Anticorrosion agent in the coolant will be diluted if a reduced mixture is used. A higher mixture can negatively influence the cooling capacity. Salt water or water with a high lime content can cause corrosion or deposits in the cooling system. Coolant filling The engine is water cooled. In the event of a high engine coolant temperature being indicated, check the coolant level first.
Presentation IMPORTANT INFORMATION: Never fill a hot engine with cold coolant. Risk of extensive engine damage. Only fill antifreeze and water ready mixed in a 50/50 ratio. Check the level when the engine has been driven for a few minutes after filling. There could have been air in the system which has now been released. Antifreeze Only use a glycol based antifreeze that is approved by the applicable norms BS 6580:1992 or ASTMD 3306-89 or AS 2108-1977 (indicated on the packaging).
