MAINTENANCE
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.
