Refilling coolant

Warning
Danger of poisoning Coolants are poisonous and a health hazard.
Avoid contact between coolants and skin, eyes and clothing. If fuel gets into your eyes, rinse immediately with water and
contact a doctor. Wash affected skin areas immediately with soap and water. If coolant is swallowed, contact a doctor im-
mediately. Change clothes that have come into contact with coolants. Keep coolants out of the reach of children.

Glass fiber yarn filling of main silencer

The main silencer is filled with glass fiber yarn.
Over a period, the fibers of the insulating material vanish into the air, and the silencer "burns out".
Not only is the noise level higher, the performance characteristic changes.
