Begin on the top side of the bar. Make sure that the edges on the cutting links are facing forward on the top side of the bar. Fit the clutch cover and locate the chain adjuster pin in the hole on the bar. Check that the drive links of the chain fit correctly on the drive sprocket and that the chain is in the groove on the bar. Tighten the bar nuts finger tight. Tension the chain by using the combination wrench. Turn the chain adjuster screw clockwise. The chain should be tensioned until it fits snugly on the underside of the bar. Hold up the tip of the bar and tighten the chain. The chain is correctly tensioned when there is no slack on the underside of the bar, but it can still be turned easily by hand. Hold up the bar tip and tighten the bar nuts with the combination wrench. When fitting a new chain, the chain tension has to be checked frequently until the chain is run-in. Check the chain tension regularly. A correctly tensioned chain gives good cutting performance and long lifetime. Mounting guide bar and chain Always wear gloves, when working with the chain, in order to protect your hands from injury. Check that the chain brake is in disengaged position by moving the front hand guard towards the front handle. Take off the bar nuts and remove the clutch cover. Take off the transportation ring (A).

The chain saw is equipped with a two-stroke engine and must always been run using a mixture of petrol and two-stroke engine oil. It is important to accurately measure the amount of oil to be mixed to ensure that the correct mixture is obtained. When mixing small amounts of fuel, even small inaccuracies can drastically affect the ratio of the mixture. Always provide for good ventilation when! handling fuel. Petrol • Use good quality unleaded or leaded petrol. • The lowest octane recommended is 90. • If you run the engine on a lower octane grade than 90 so-called, knocking can occur. This gives rise to a high engine temperature, which can result in serious engine damage. • When working with continuous high revs (e.g. delimbing) a higher octane grade is recommended. Two-stroke oil • For the best results use JONSERED two-stroke oil, which is especially developed for chain saws. Mixing ratio 1:50 (2%). • If JONSERED 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. Mixing ratio 1:33 (3%)-1:25 (4%). • Never use two-stroke oil intended for water cooled outboard motors, so-called, outboard oil. • Never use oil intended for four-stroke engines.

Then add the entire amount of oil. Mix (shake) the fuel mixture. Add the remaining amount of petrol. • Mix (shake) the fuel mixture thoroughly before filling the saw’s fuel tank. • Do not mix more than approx. 1 month supply of fuel. • If the saw is not used for some time the fuel tank should be emptied and cleaned. 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, EP 90 transmission oil 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 less 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 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. English – 27 START AND STOP Start and stop ! WARNING! • Never start the saw engine without the bar, chain and clutch cover (chain brake) assembled ...
