The throttle lock (4) must be pressed down before the trigger will actuate the throttle. Fan casing (7) The blower fan casing (7) together with the impeller (13) provide high performance air discharge. Inspection cover (11) An inspection cover is located on the underside of the fan casing. Removal of this cover allows access for cleaning and inspecting the impeller. The inspection cover can only be opened by means of tools. If the vacuum tube is used, it must be fitted to the opening in the inspection cover as shown on page 16. ! ! WARNING! Never start the blower if the inspection cover is not closed, is damaged or cannot be closed. (Exception: When the vacuum tube is fitted). Cutters (12) Two cutters are fastened to the impeller. The cutters are there to mulch leaves and other debris, that have been vacuumed, before they enter the fan inlet. 4 Nozzle (14) and blower tube (15) The nozzle and the blower tube have a bayonet mount for connection to the blower. Air is channeled through the blower tube to the nozzle, where the air discharge velocity increases and the air stream discharge pattern is formed to provide best performance. 15 14 2 7 13 12 11 English – 9 DESCRIPTION Starter device (18) and starter handle (17) The starter device is located at the top on the engine shrouding and engages in the crank shaft only when the starter handle is pulled. Fuel cap (8) The fuel cap (14) is located at the top of the engine shrouding and has a gasket, which prevents fuel from leaking out. Air filter (9) The air filter consists of foam-rubber filter medium, integrated in a plastic casing. The air filter should be cleaned at specific intervals. Otherwise, the power blower will consume too much fuel, the performance will be reduced and an oily deposit may form on the spark plug electrodes. Choke (10) The choke is located at the top of the engine shrouding and should be used every time the engine is cold-started. The choke is de-activated automatically when the throttle trigger is pressed. Adjusting the carburetor (19) There are three adjusting screws for adjusting the carburetor: • Low speed jet • High speed jet • Adjustment screw for idling Adjusting the carburetor involves adapting the engine to local operating conditions, e.g. climate, altitude, gasoline and type of two-stroke engine oil used. For details about carburetor adjustment, see page 18. 17 18 8 9 19 10 10 – English FUEL HANDLING Fuel mixture NOTE! The machine is fitted with a two-stroke engine and must always be run on a mixture of gasoline and two- stroke oil. It is important to measure the quantity of oil accurately, to ensure the correct mixture ratio. Small discrepancies in the amount of oil have a great bearing on the proportions of the fuel mixture when mixing small amounts of fuel. ! WARNING! Allow adequate ventilation while handling fuel. Gasoline NOTE! Always use an oil-mixed quality gasoline (at least 87 octane). If your machine is equipped with a catalytic converter, (see “technical data”)an unleaded, oil mixed quality gasoline should always be used. A leaded gasoline will destroy the catalytic converter. • This engine is certified to operate on unleaded gasoline. • The lowest recommended octane rating is 87. If you run the engine on lower octane rating than 87 so-called “knocking“ can occur. This leads to an increased engine temperature, which can result in a serious engine breakdown. • When working at continuous high revs a higher octane rating is recommended. Two-stroke oil • For the best performance, use HUSQVARNA two-stroke oil, which has been specially developed for Husqvarna two-stroke engines. Mixing ratio: 1:50 (2%). • If HUSQVARNA two-stroke oil is not available, you may use another two-stroke oil of good quality that is intended for air-cooled engines. Contact your dealer when selecting an oil. • Never use two-stroke oil intended for water- cooled marine outboard motors, so-called outboard oil. • Never use oil intended for four-stroke engines. English – 11 FUEL HANDLING Mixture • Always mix gasoline and oil in a clean container intended for fuel. • Always start by filling half the quantity of gasoline required. Then add the entire oil quantity. Mix (shake) the fuel mixture. Fill the remaining quantity of gasoline. • Mix (shake) the fuel mixture carefully before filling in the machine‘s fuel tank. • Do not mix more than max. one month’s supply of fuel. • If the machine is not used for a long period of time, the fuel tank should be emptied and cleaned. • This engine is certified to operate on unleaded gasoline. ! ! WARNING! The catalytic converter muffler gets very hot during and after use. This also applies during idling. Be aware of the fire hazard, especially when handling the saw near flammable substances or vapours. Fuelling ! ! WARNING! The following precautions reduce the risk of fire: Do not smoke or place any sources of heat in the vicinity of the fuel. Never refuel when the engine is running. Always stop the engine and let it co...
