Air filter

MAINTENANCE

The air filter should be cleaned regularly removing dust and dirt to avoid:

•carburetor malfunction

•starting problems

• reduced engine power

•unnecessary wear to engine parts

•abnormal fuel consumption Clean the filter after every 25 hours or more regularly if operating conditions are exceptionally dusty.

Cleaning the air filter

Dismantle the air filter cover and remove the air filter. Wash in clean, warm soapy water. Ensure that the filter is dry before refitting. An air filter used for a long period of time can never be cleaned completely. Therefore it is necessary to replace the filter from time to time with a new filter. A damaged air filter must always be replaced.

If the machine is used in dusty conditions the air filter should be soaked in oil, see the section on “Oiling the air filter“.

Oiling the air filter

Always use HUSQVARNA filter oil, order no. 503 47

73-01. The 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 the 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 on the machine. Never use common

engine oil. This would drain through the filter quite quickly and collect in the bottom.

Angle gear (326L, 326LX, 326LDX)

The angle gear is filled with a sufficient quantity of grease at the factory. However, before using the machine you should check that the angle gear is filled to 3/4 with grease. Use special grease.

Normally, the grease does not need to be changed except when repairs are carried out.

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.
