Note: An air filter that has been in use for a long time
can't be clean completely. The filter must therefore be
replaced with a new one at regular intervals. Always
replace a damaged air filter.
4. Refit the air filter and make sure that the air filter
seals tightly against the filter holder.
A Zenoah chainsaw can be equipped with different types
of air filter according to working conditions, weather,
season etcetera. Contact your servicing dealer for
advice.
To do a check of the spark plug
The spark plug condition is influenced by an incorrect
carburetor adjustment, an incorrect fuel mixture (too
much or incorrect type of oil) and a dirty air filter. These
factors cause deposits on the spark plug electrodes,
which may result in operating problems and starting
difficulties.
Note: Always check the spark plug before you take any
further action if the product is low on power, difficult to
start or runs poorly at idle speed.
1. Clean the spark plug if it is dirty.
2. Do a check of the electrode gap and make sure that
it is 0,65 mm.

3. Replace the spark plug once a month or earlier if
necessary.
CAUTION: Always use the recommended
spark plug type! Use of the wrong spark plug
can damage the piston/cylinder. For
recommended spark plug, see heading

Sharpening of the saw chain
General advice on sharpening the cutting
teeth
Never use a blunt saw chain. When the saw chain is
blunt you have to exert more pressure to force the bar
through the wood and the chips will be very small. If the
saw chain is very blunt it will produce wood powder and
no chips or shavings.
A sharp saw chain eats its way through the wood and
produces long, thick chips or shavings.
The cutting part of the saw chain is called the cutter and
consists of a cutting tooth (A) and the depth gauge (B).
The cutters cutting depth is determined by the difference
in height between the two (depth gauge setting).
When you sharpen a cutting tooth there are four
important factors to remember:
