Oiling the air filter
Always use special filter oil. Filter oil contains a solvent to
make it spread evenly through the filter. You should therefore
avoid skin contact.
Put the filter in a plastic bag and pour the filter oil over it.
Knead the plastic bag to distribute the oil. Squeeze the
excess oil out of the filter inside the plastic bag and pour off
the excess before fitting the filter to the machine. Never use
common engine oil. This would drain through the filter quite
quickly and collect in the bottom.
Spark plug
The spark plug condition is influenced by:
Incorrect carburetor 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 0.020 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.
Check that the spark plug is fitted with a suppressor.
Note: Use only HUSQVARNA replacement parts. Use of
other brands of replacement parts can cause damage to
your unit or injury to the operator or others. Your warranty
does not cover damage or liability caused by the use of
accessories and/or attachments not specifically
recommended by HUSQVARNA.
