• 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 (10ft) 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 STARTING: The chain brake should be activated when starting the chain saw. Activate the chain brake by pushing the front hand guard forwards. 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 (A): 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. A 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. Never wrap the starter cord around your hand. Push in the choke control immediately when the engine ignites and make repeated starting attemps. Immediately press and release the throttle when the engine starts. That will disengage the throttle latch. As the chain brake is still activated the engine must return to idling speed as soon as possible by disengaging the throttle latch in order to avoid unnecessary wear on the clutch assembly. CAUTION! Do not release the starter handle from fully pulled out position as this can cause damage on the saw. Pull the front hand guard towards the front handle. The chain brake is now disengaged. Your saw is now ready for use. Stop The engine is stopped by switching off the ignition. 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. • The setting of the carburetor means that the engine is adapted to local conditions, for example, the climate, altitude, fuel and the type of 2-stroke oil. • The carburetor has three LT H adjustment possibilities: L = Low speed jet. H = High speed jet. T = Adjustment screw for idling. • The fuel quantity required in relation to the air flow, provided by opening the throttle, is adjusted by the L and H-jets. If they are screwed clockwise the air/fuel ratio becomes leaner (less fuel) and if they are turned counter-clockwise the ratio becomes richer (more fuel). A leaner mixture gives a higher engine speed and a richer mixture give a lower engine speed. • The T screw regulates the idling speed. If the screw T is turned clockwise this gives a higher idling speed; counterclockwise a lower idling speed. Basic setting and running in The carburetor is set to its basic setting when test run at the factory. The basic setting should be kept during the machine‘s first working hours. Thereafter the carburetor should be finely adjusted. Fine adjustment should be carried out by a skilled technic...
