Muffler with catalytic converter

Cooling system

A muffler fitted with a catalytic converter reduces the extent of the following substances in the exhaust fumes:

•Hydrocarbons (HC). Some hydrocarbons in gasoline and the exhaust are carcinogenic.

•Nitric oxides (NO). Irritating for the breathing air-ways.

•Aldehydes. The most common formaldehyde, is carcinogenic and causes hypersensitiveness.

NOTE! The level of carbon monoxide is not reduced. This is an odourless and extremely poisonous substance. Therefore avoid exposure without good air circulation.

The muffler is also designed to dampen the noise level and to direct the exhaust fumes away from the user. The exhaust fumes are hot and can contain sparks, which can result in fire if the exhaust fumes are directed towards a dry or inflammable material. Some mufflers are fitted with a special spark arrest screen. If your machine is fitted with this type of muffler then the screen should be cleaned at least once a week. This is done using a wire brush. If the screen is damaged in any way it should be replaced. If the screen is blocked this will result in engine overheating

To maintain as low operating temperature as possible the engine is equipped with a cooling system.

The cooling system consists of:

1.An air intake on the starter unit.

2.Cooling fins on the flywheel.

3.Cooling fins on the cylinder

4.Cylinder cover (leads cold air onto the cylinder).

Clean the cooling system using a brush at least once a week, in difficult conditions more often.

A dirty or blocked cooling system leads to the engine overheating resulting in damage to the cylinder and piston.

and damage to the cylinder and piston.

NOTE!

Never use a machine with a defective muffler.

The condition of the spark plug is affected by:

•An incorrect carburetor setting.

•An incorrect fuel mixture (too much or faulty oil).

•A dirty air filter.

These factors cause deposits on the spark plug electrode that may result in malfunction or starting difficulties.

!WARNING!

Mufflers fitted with catalytic converters become extremely hot during use and after stopping. This also applies at idling speeds. Contact can result in burns to the skin. Be observant to the risk of fire!

!WARNING!

The coating on/in the catalytic element can be hazardous to health if consumed. Wear gloves when carrying out service work on the catalytic converter.

If the machine is low on power, difficult to start or runs poorly while idling always check the spark plug first.

If the spark plug is dirty, clean it and at the same time check that the electrode gap is 0.5 mm. The spark plug should be changed after about one month of operation or earlier if neces- sary.

NOTE! Always use the recommended type of spark plug. An incorrect spark plug can damage the cylinder/piston.
