MAINTENANCE 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. Adjustment of the oil pump Note! 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. Lubricating the bar tip sprocket The oil pump is adjustable. Adjustments are made by turning the screw using a screwdriver or combination spanner. The machine is supplied from the factory set to 1 turn open. Turning the screw clockwise will reduce the oil flow and turning the screw anti-clockwise will increase the oil flow. Lubricate the bar tip sprocket each time you refuel. Use the special grease gun and a good quality bearing grease. Needle bearing lubrication Recommended settings: Bar -15": Bar 15" -18": 1 turn from the closed position. 2 turns from the closed position. Bar 18" -24": Bar 24" -: 3 turns from the closed position. 4 turns from the closed position. These recommendations apply to Husqvarna's chain oil, for other chain oils increase the oil flow by one step. WARNING! The engine must be stopped ! when making adjustments. The clutch drum has a needle bearing on the output shaft. This needle bearing must be lubricated regularly (once a week). When lubricating, remove the clutch cover by loosening the two bar nuts. Lay the saw on its side with the clutch drum upwards. Lubrication involves engine oil dripping into the centre of the clutch drum as it rotates. Cooling system To keep the working temperature as low as possible the machine is equipped with a cooling system. The cooling system consists of: 1 Air intake on the starter. 2 Air guide plate. 3 Fins on the flywheel. 4 Cooling fins on the cylinder. 5 Cylinder cover (directs cold air over the cylinder).
