Vibration damping system
Regularly check the vibration damping units for cracks or 
deformation.
Make sure the vibration damping units are securely 
attached to the engine unit and handle unit.
Stop switch
Start the engine and make sure the engine stops when 
you move the stop switch to the stop setting.
Muffler
Never use a machine that has a faulty muffler.
Regularly check that the muffler is securely attached to 
the machine.
Some mufflers are equipped with a special spark arrestor 
screen. If your machine has this type of muffler, you 
should clean the screen at least once a week. This is best 
done with a wire brush. A blocked screen will cause the 
engine to overheat and may lead to serious damage.
Note! The screen must be replaced if it is damaged. If the 
screen is blocked the machine will overheat and this will 
cause damage to the cylinder and piston. Never use a 
machine with a muffler that is in poor condition. Never 
use a muffler if the spark arrestor screen is missing 
or defective.
The muffler is designed to reduce the noise level and to 
direct the exhaust gases away from the operator. The 
exhaust gases are hot and can contain sparks, which may 
cause fire if directed against dry and combustible 
material.
A muffler equipped with a catalytic converter significantly 
reduces the amount of hydrocarbons (HC), nitrogen 
oxides (NO) and aldehydes in the exhaust fumes. Carbon 
monoxide (CO), which is poisonous and odorless, is not 
however reduced! Consequently, never work in an 
enclosed or badly ventilated area. Good air circulation 
should always prevail when working in snowy hollows, 
ravines or in confined conditions.
