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.

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.
