MAINTENANCE

Air filter

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

•carburetor malfunction

•starting problems

•reduced engine power

•unnecessary wear to engine parts

•abnormal fuel consump- tion

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

Gearbox

There is a grease nipple (A) on the gearbox. Use a grease gun to top up with grease.

This should be carried out after approximately every 20 working hours. Use Husqvarna special grease, No. 503 98 96-01.

Note that the gearbox must not be filled completely with grease. The grease expands as the machine heats up during operation. If the gearbox was completely filled with grease it could damage the seals and lead to leakage.

Cleaning the air filter

Dismantle the air filter cover (B) 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.

The lubricant in the gearbox does not normally need to be replaced other than with repair.

Cleaning and lubrication

After you have used the machine clean any resin and plant residue from the blades using cleaning agent 531 00 60-75 (UL22).

Always lubricate the blade runners with special grease 531 00 60-74 (UL 2001) before use.
