MAINTENANCE

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.
