The spark plug condition is influenced by:

•

Incorrect carburetor adjustment.

•

Wrong fuel mixture (too much oil).

•

A dirty air filter.

These factors cause deposits on the spark plug electrodes, 
which may result in operating problems and starting 
difficulties.

•

If the machine is low on power, difficult to start or runs 
poorly at idle speed: always check the spark plug first 
before taking any further action. If the spark plug is dirty, 
clean it and check that the electrode gap is 0.020 inch (0.5 
mm). The spark plug should be replaced after about a 
month in operation or earlier if necessary.

CAUTION! Always use the recommended spark plug type! 
Use of the wrong spark plug can damage the piston/cylinder.

To keep the working temperature as low as possible the 
machine is equipped with a cooling system.

The cooling system consists of:

1

Air intake on the starter.

2

Air guide plate.

3

Fins on the flywheel.

4

Cooling fins on the cylinder.

5

Cylinder cover

Clean the cooling system with a brush once a week, more 
often in demanding conditions. A dirty or blocked cooling 
system results in the machine overheating which causes 
damage to the piston and cylinder.

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.

Never use a machine with a defective muffler.
