English- ---15 MAINTENANCE Maintenance Safety The owner is responsible for the performance of all required maintenance as defined in the operator’s manual. Disconnect the spark plug before performing maintenance, except carburetor adjustments. BB WARNING: Improper maintenance could result in serious engine damage or in serious injury. Carburetor Your Husqvarna product has been designed and manufactured to specifications that reduce harmful emissions. After the engine has used 8- --10 tanks of fuel, the engine will be run- --in. To ensure that it continues to run at peak performance and to minimize harmful exhaust emissions after the run- --in period, ask your servicing dealer to adjust your carburetor. Function S The carburetor governs the engine’s speed via the throttle control. Air and fuel are mixed in the carburetor. S The T- --screw (BB) regulates the throttle setting at idle speed. If the T- --screw is turned clockwise this gives a higher idle speed; turning it counterclockwise gives a lower idle speed. Basic setting S The basic carburetor settings are adjusted during testing at the factory. Fine adjustment should be carried out by a skilled technician. Recommended idle speed: See “Technical data” section. Recommended max. speed: See “Technical data” section. Fine adjustment ofthe idle speed- --T Adjust the idle speed using the idle adjustment T- --screw if it is necessary to readjust. The idle speed is correctly adjusted when the engine will run smoothly in every position. Muffler Some mufflers are fitted with catalytic converters. See the Technical data section to find out if your machine is equipped with a catalytic converter. The muffler is designed to dampen the noise level and to direct the exhaust fumes away from the user. The exhaust fumes are hot and can contain sparks, which can result in fire if the exhaust fumes are directed towards a dry and flammable material. Some mufflers are equipped with a special spark arresting screen (CC). If your machine is fitted with this type of screen, it should be cleaned regularly. To access the screen, remove the outlet cover on the front of the muffler. Use a wire brush to clean the screen. On mufflers without a catalytic converter the screen should be cleaned weekly, or replaced if necessary. On mufflers fitted with a catalytic converter the screen should be checked and cleaned monthly. If the screen is damaged it should be replaced. If the screen is frequently blocked, this can be a sign that the function of the catalytic converter is impaired. Contact your dealer to inspect the muffler. A blocked screen will cause the engine to overheat resulting in damage to the cylinder and piston. CAUTION! Never use a machine that has a faulty or loose muffler. Ensure the muffler bolts are tight. 545154658 Rev. 2 7/10/07 English- ---16 MAINTENANCE CC WARNING: Mufflers fitted with catalytic converters get very hot duringuse andremainsofor some time after stopping. This also applies at idle speed. Contact can result in burns to the skin. Remember theriskof fire! WARNING: Bear in mind that: Engine exhaust fumes contain carbon monoxide, which can cause carbon monoxide poisoning. For this reason yo...
