This results in damage to the oil pump, the bar and the chain. • It is important to use oil of the right grade (suitable viscosity range) to suit the air temperature. • In temperatures below 0°C (32°F) some oils become too viscous. This can overload the oil pump and result in damage to the oil pump components. • Contact your service agent when choosing chain oil. 26 – English FUEL HANDLING Fuelling ! WARNING! Taking the following precautions, will lessen the risk of fire: Do not smoke or place hot objects near fuel. Always shut off the engine before refuelling. When refuelling, open the fuel cap slowly so that any excess pressure is released gently. Tighten the fuel cap carefully after refuelling. Always move the machine away from the refuelling area before starting. Clean the area around the fuel cap. Clean the fuel and chain oil tanks regularly. The fuel filter must be replaced at least once a year. Contamination in the tanks causes malfunction. Make sure the fuel is well mixed by shaking the container before refuelling.The capacities of the chain oil tank and fuel tank are carefully matched.You should therefore always fill the chain oil tank and fuel tank at the same time. Min 3 m (10ft) English – 27 STARTING AND STOPPING Starting and stopping ! WARNING! Note the following before starting: Never start a chain saw unless the bar, chain and all covers are fitted correctly. Otherwise the clutch can come loose and cause personal injuries. Always move the machine away from the refuelling area before starting. Place the machine on firm ground. Make sure you have a secure footing and that the chain cannot touch anything. 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: Slide the ignition switch to the left. Choke: Set the choke control in the choke position. Start throttle: The correct choke/start throttle setting is obtained by moving the control to the choke position. If the machine is fitted with a decompression valve (A): Press the valve to reduce the pressure in the cylinder and make starting easier.You should always use the decompression valve when starting the machine. Once the machine has started the valve will automatically return to its original setting. Warm engine Use the same procedure as for starting a cold engine but without setting the choke control in the choke position. The correct choke/start throttle setting is obtained by moving the choke control to the choke position and then pushing it in again. Starting Grip the front handle with your left hand. Hold the chain saw on the ground by placing your right foot through the rear handle. Pull the starter handle with your right hand and pull out the starter cord slowly until you feel a resistance (as the starter pawls engage) then pull firmly and rapidly. Never wrap the starter cord around your hand As the chain brake is still activated the engine must return to idling speed as soon as possible by disengaging the throttel latch in order to avoid unnecessery wear on the clutch assembly. Push in the choke control as soon as the engine fire and make repeated starting attempts. Immediately press and release the throttle when the engine starts. That will disengage the throttle latch. CAUTION! Do not pull the starter cord all the way out and do not let go of the starter handle when the cord is fully extended. This can damage the machine. 28 – English STARTING AND STOPPING Pull the front hand guard towards the front handle. The chain brake is now disengaged.Your saw is ready for use. Stopping Stop the engine by switching off the ignition. English – 29 MAINTENANCE Carburettor Your Jonsered product has been designed and manufactured to specifications that reduce harmful exhaust fumes. Function, Basic settings, Fine adjustment ! WARNING! Do not start the chain saw unless the bar, chain and clutch cover (chain brake) are fitted, otherwise the clutch may come loose and cause personal injury. Function • The carburettor governs the engine’s speed via the throttle control. Air and fuel are mixed in the carburettor. The air/fuel mixture is adjustable. Correct adjustment is essential to get the best performance from the machine. • The setting of the carburettor means that the engine is adepted to local conditions, for example, the climate, altitude, fuel and the type of 2-stroke oil. • The carburettor has three adjustment controls: - L = Low speed jet - H = High speed jet - T = Idle adjustment screw L HT • The L and H-jets are used to adjust the supply of fuel to match the rate that air is admitted, which is controlled with the throttle. If they are screwed clockwise the air/fuel ratio becomes leaner (less fuel) and if they are turned anti- clockwise the ratio becomes richer (more fuel). A lean mixture gives a higher engine speed and a rich mixture gives a lower engine speed. • The T-screw regul...
