1. Remove the air filter cover and the air filter.
2. Use a brush or shake the air filter clean. Use
detergent and water to clean it fully.
Note:
An air filter that is used for a long time can
not be fully cleaned. Replace the air filter regularly
and always replace a damaged air filter.
3. Attach the air filter and make sure that the air filter
seals tightly against the filter holder.
Note:
Because of different work conditions, weather
or season, your product can be used with different types
of air filter. Speak to your servicing dealer for more
information.
To do a check of the spark plug
CAUTION:
Use the recommended
spark plug. Refer to
35
. An incorrect spark plug can cause
damage to the product.
1. If the product is not easy to start or to operate
or if the product operates incorrectly at idle speed,
examine the spark plug for unwanted materials. To
decrease the risk of unwanted material on the spark
plug electrodes, do these steps:
a) make sure that the fuel mixture is correct.
b) make sure that the air filter is clean.
2. Clean the spark plug if it is dirty.
3. Make sure that the electrode gap is 0.65 mm/0.026
in.
4. Replace the spark plug monthly or more frequently if
necessary.

Information about the guide bar and saw chain
WARNING:
Use protective gloves
when you use or do maintenance on the
saw chain. A saw chain that does not move
can also cause injuries.
Replace a worn or damaged guide bar or saw chain with
the guide bar and saw chain combination recommended
by Zenoah. This is necessary to keep the safety
functions of the product. Refer to
page 36
, for a list of replacement bar and chain
combinations that we recommend.
• Guide bar length, in/cm. Information about the guide
bar length can usually be found on the rear end of
the guide bar.

of the saw chain must align with the distance of the
