Husqvarna 325HE3 Operation Manual - Page 20

MAINTENANCE spark plug should be replaced after about a month in operation or earlier if necessary. Oiling the air filter 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. Air filter Always use HUSQVARNA filter oil, art. no. 531 00 92-48. 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 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. The air filter must be regularly cleaned to remove dust and dirt in order to avoid: • Carburettor malfunctions • Starting problems • Loss of engine power • Unnecessary wear to engine parts. • Excessive fuel consumption. Clean the filter every 25 hours, or more regularly if conditions are exceptionally dusty. Gear There is a grease nipple and a plug for filling lubricant on the gear housing. Use a grease gun to fill with grease. New machines are first filled with grease after approximately 20 hours of operation, and subsequently approximately every 60 hours of operation. Use Husqvarna's special grease, no. 503 98 96-01. Cleaning the air filter Remove the air filter cover and take out the filter. Wash it clean in warm, soapy water. Ensure that the filter is dry before refitting it. An air filter that has been in use for a long time cannot be cleaned completely. The filter must therefore be replaced with a new one at regular intervals. 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 instructions under the heading Oiling the air filter. CAUTION! The gear housing must not be filled completely with grease. The grease expands as the machine heats up during operation. If the gear housing was completely filled with grease it could damage the seals and lead to leakage of grease. The grease in the bevel gear does not normally need to be changed except if repairs are carried out. 20 - English
