Use HUSQVARNA special grease. The grease in the bevel gear does not normally need to be changed except if repairs are carried out. Air filter 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. ! WARNING! Mufflers fitted with catalytic converters get very hot during use and remain so for some time after stopping. This also applies at idle speed. Contact can result in burns to the skin. Remember the risk of fire! MAINTENANCE 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. Oiling the air filter Always use special filter oil. 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. 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. English – 21 MAINTENANCE Maintenance schedule The following is a list of the maintenance that must be performed on the machine. Most of the items are described in the Maintenance section.

Maintenance Daily maintenance Weekly maintenance Monthly maintenance Clean the outside of the machine. X Make sure the throttle trigger lock and the throttle function correctly from a safety point of view. X Check that the stop switch works correctly. X Check that the cutting attachment does not rotate at idle. X Clean the air filter. Replace if necessary. X Check that the guard is undamaged and not cracked. Replace the guard if it has been exposed to impact or is cracked. X Check that the trimmer head is undamaged and not cracked. Replace the trimmer head if necessary. X Check that the locking nut of the cutting equipment is tighten correctly. X Check that nuts and screws are tight. X Check that there are no fuel leaks from the engine, tank or fuel lines. X Check the starter and starter cord. X Check that the vibration damping elements are not damaged. X Clean the outside of the spark plug. Remove it and check the electrode gap. Adjust the gap to 0.5 mm (.20”), or replace the spark plug. Check that the spark plug is fitted with a suppressor. X Clean the machine’s cooling system. X Clean or replace the spark arrestor screen on the muffler (only applies to mufflers without a catalytic converter). X Clean the outside of the carburettor and the space around it. X Check that the bevel gear is filled three-quarters full with lubricant. Fill if necessary using special grease. X Check the fuel filter from contamination and the fuel hose from cracks or other defects. Replace if necessary. X Check all cables and connections. X Check the clutch, clutch springs and the clutch drum for wear. Replace if necessary by an autorized service workshop. X Replace the spark plug.
