Facilità d'uso
• If the saw is not used for some time the fuel tank should be emptied and cleaned. • This engine is certified to operate on unleaded gasoline. Chain oil • The chain lubrication system is automatic. Always use special chain oil with good adhesive characteristics. • In countries where no special chain oil is available, transmission oil EP 90 can be used. • Never use waste oil. This results in damage to the oil pump, the bar and the chain. • It is important to use oil of the right viscosity according to the air temperature. • In temperatures below 0oC (32oF) some oils become too viscous. This can overload the oil pump and result in damage to the oil pump components. • Contact your servicing dealer when choosing chain oil. 26 – English FUEL HANDLING The oil pump The chain is lubricated by an automatic oil pump. The pump does not normally require any maintenance, provided that clean chain oil (of special type) is used, and that no dirt is allowed to get into the tank during filling. The flow of oil to the chain can be regulated by means of an adjuster screw as indicated in the illustration above, using a screwdriver or combination key. For maximum flow, turn the screw in a clockwise direction as far as it will go. The oil pump is adjusted at the factory to supply a normal flow of oil to the chain. The settings should be such that the saw's fuel and oil tanks run dry at the same time. Fuelling ! ! Taking the following precautions, will lessen the risk of fire. • Do not smoke or place warm objects in the vicinity of the fuel. • Always shut off the engine before refuelling. • Slowly open the fuel cap, when filling fuel, so that possible overpressure is slowly released. • Tighten the fuel cap carefully after fuelling. • Always move the saw from the fuelling area before starting. Clean around the fuel cap. Clean the fuel and chain oil tanks regularly. The fuel filter should be changed at least once a year. Contamination in the fuel tanks causes malfunction. Make sure the fuel is well mixed by shaking the container before fuelling. The volume of chain oil and fuel tanks are adjusted to each other. Therefore, always fill chain oil and fuel at the same time. Min. 3 m (10 ft) English – 27 START AND STOP Start and stop ! ! WARNING! • Never start the saw engine without the bar, chain and clutch cover (chain brake) assembled - or else the clutch can come loose and cause personal injuries. • Always move the saw away from the fueling area before starting. • Place the saw on clear ground and make sure that the chain is not contacting anything. Also, make sure that you have a secure footing. • Keep people and animals well away from the working area. Cold engine CHAIN BRAKE: Disengage the chain brake by pulling the hand guard towards the front handle. IGNITION: Move the ignition switch to startposition. CHOKE: Set the choke control in choke position. FAST IDLE: Combined choke/fast idle is received when the choke is moved to choke position. If the saw is fitted with a decompression valve: Press the valve to reduce the pressure in the cylinder and make starting easier. Always use the decompression valve when starting the saw. Once the saw has started the valve will automatically return to its original setting. Warm engine Use the same procedure as for starting cold engine but without choke. Fast idle is recived by first set the choke control in choke position, and then back again. Start Grip the front handle with your left hand and hold the saw down by putting your right foot in the rear handle. Pull the starter handle with your right hand and pull out the starter cord slowly until the starter pawls engage. Then pull sharply. Push in the choke control immediately when the engine ignites and make repeated starting attemps. When the engine starts, rapidly give full throttle. Then the throttle latch will disengage. CAUTION! Do not release the starter handle from fully pulled out position as this can cause damage on the saw. Stop The engine is stopped by switching off the ignition. (Move the ignition switch to stopposition.) 28 – English MAINTENANCE Carburetor CarburetorCarburetor Your Jonsered product has been designed and manufactured to specifications that reduce harmful emissions. After your unit has been run 8-10 tanks of fuel the engine has broken in. To ensure that your unit is at peak performance and producing the least amount of harmful emissions after break in, have your authorized servicing dealer, who has a revolution counter at his disposal, to adjust your carburetor for optimum operating conditions. Functioning, Basic setting, Final setting ! ! WARNING! Do not start the saw without the bar, chain and clutch cover (chain brake) assembled. If you do, the clutch might come loose and cause severe injuries. Operation • The carburetor governs the engine speed via the throttle. Air/ fuel are mixed in the carburetor. The air/fuel mixture is adjustable. To take advantage of the engine’s optimal output the setting must be correct...
