2 – English Safety regulations General instructions The workshop handbook is written for personnel who are assumed to have general ride-on mower reparation and service know-how. The workshop where the ride-on mower is repaired should be equipped with safety devices in accordance with local regulations. No-one should attempt to repair the ride-on mower without having first read and understood the contents of this handbook. The machine is tested for safety and approved only for equipment supplied or recommended by the manufacturer. The below-mentioned boxes are included in this workshop handbook, as is appropriate. Special instructions The fuel used in the ride-on mower has the following hazardous characteristics: • Toxic fluid and fumes • Can cause eye and skin complaints • Can cause breathing difficulties • Highly flammable 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 . 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. The blades are sharp and can cause cutting injuries. Always use protective gloves when you are handling the blades. 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. 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 This box indicates a risk of damage to the material if the instructions are not followed. WARNING! The warning box indicates a risk of injury to persons if the instructions are not followed. ! For Husqvarna Parts Call 606-678-9623 or 606-561-4983 www.mymowerparts.com
