The spark plug condition is influenced by:

•

Incorrect carburettor adjustment.

•

An incorrect fuel mixture (too much or incorrect type of 
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 0.5 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.

See the cutting attachment packaging for correct 
sharpening instructions.

•

Sharpen blades and cutters using a single-cut flat file.

•

Sharpen all edges equally to maintain the balance of the 
blade.

•

See the cutting attachment packaging for correct 
sharpening instructions. A correctly filed blade is essential 
for working efficiently and to avoid unnecessary wear to 
the blade and clearing saw.

•

Make sure that the blade is well supported when you file 
it. Use a 5.5 mm round file with a file holder.

•

The filing angle is 15

°. File alternate teeth to the right and 

those in between to the left. If the blade has been heavily 
pitted by stones it may be necessary to dress the top 
edges of the teeth with a flat file, in exceptional cases. If 
so, this should be done before filing with a round file. The 
top edges must be filed down by the same amount for all 
the teeth.

•

Adjust the blade setting. This should be 1 mm.
