  3. Safety regulations Special instructions The fuel used in the ride-on mower has the following hazardous characteristics: General instructions The workshop handbook is written for personnel who are assumed to have general ride-on mower repara- tion and service know-how. • Toxic fluid and fumes • Can cause eye and skin complaints The workshop where the ride-on mower is repaired should be equipped with safety devices in accordance with local regulations. • Can cause breathing difficulties • Highly flammable No-one should attempt to repair the ride-on mower without having first read and understood the contents of this handbook. When using compressed air, do not direct the compressed air stream towards your, or anybody else's, body. Air can be forced into the blood stream, thereby constituting a danger to life . The machine is tested and approved only with the equipment originally provided or recommended by the manufacturer. Use eye protection when working with tensioned springs. The below-mentioned boxes are included in this workshop handbook, as is appropriate. Use hearing protectors when test driving. After test driving, do not touch the silencer before it has cooled down. Risk of burn injuries. This especially applies if the ride-on mower is equipped with a catalytic converter. If consumed, the lining on and in the catalytic converter element is dangerous to health. Use protective gloves when working with the catalytic converter/silencer. WARNING! The warning box indicates a risk of injury to persons if the instructions are not followed. The blades are sharp and can cause cutting injuries. Always use protective gloves when you are handling the blades. IMPORTANT INFORMATION This box indicates a risk of damage to the material if the instructions are not followed. Use protective glasses when working with the mowing deck. If the belt's tension spring comes off and flies upwards, this can cause injury to persons. Use eye protection when working with the battery with the plugs removed. Be extra careful when handling battery acid. Spilling acid on the skin can cause severe burn injuries. If acid is spilt on the skin, rinse immediately with water. If acid gets into the eyes, this can cause blindness, contact a doctor. Be careful with the maintenance of the battery. Explosive gas is formed in the battery. Never handle the battery when smoking or in the vicinity of naked flames or sparks. Otherwise, the battery can explode and cause severe injuries. IMPORTANT INFORMATION Waste oil and old filters shall be handled as hazardous waste. 2 – English

  21. Design and function Steering Thanks to the articulated steering, the turning radius is extremely small, the uncut circle when the steering wheel is fully turned is just 20-30 cm (8"-12")depending on which model is chosen. All the ride-on mowers in the Rider series have articulated steering. The steering force from the steering wheel is transferred to the rear section via wires and a chain. This ensures that the ride-on mower is easy to manoeuvre, as well as having high-precision steering. A Rider easily cuts around all obstacles that may be found on the lawn.
