5a. Close the bar retaining nuts, screwing by hand. 5b. Screw the bar retaining knob loosely tightened. 6a. To spread the chain screw the chain tensioner screws in a clockwise direction, to loosen tension, screw in an anti-clockwise direction (when performing this operation maintain the bar nose raised upwards) 6b. To spread the chain screw the chain tensioner knob in a clockwise direction, to loosen tension, screw in an anti-clockwise direction (when performing this operation maintain the bar nose raised upwards) 7 Spread the chain until the tension is correct; that is, when the chain is pulled upwards, the drive tooth rise to the same level as the bar. (the chain must never droop on the underside of the bar) 8a. Tighten the bar retaining nuts using an appropriate tool. 8b. Tighten the bar retaining knob strongly. Tensioning the chain too tightly will overload the motor and cause damage, insufficient tension can provoke chain derailing, whereas a chain tightened correctly provides the best cutting characteristics and prolonged work life. Check the tension regularly because the chain length tends to stretch with use (especially when the chain is new; after the first assembly, the chain tension must be controlled after 5 minutes machine operation); in any ENGLISH - 6 case do not tighten the chain immediately after use, but wait until it cools down. In cases where the loosened chain needs to be adjusted, always unscrew the bar retaining nuts / knob before adjusting the chain tensioning screw/knob ; adjust the tension and tighten the bar retaining nuts /knob accordingly. E. START-UP AND ARREST 1,4,5,6,7,8,9,11,12,13 Start-up: grip both handles firmly, release the chain brake lever, press and maintain the switch block pressed in, then press the switch (at this point the switch block can be released). Arrest: The machine will stop whenever the switch is released. In the case where the machine does not stop, activate the chain brake, disconnect the cable from the main line socket and take the machine to the Authorised Service Centre. F. BAR AND CHAIN LUBRICATION 3,6,7,8,9,12 ATTENTION! Insufficient lubrication will provoke chain breaking and can cause serious and even mortal injury. Bar and chain lubrication is performed by an automatic pump. If your machine is equipped with an oil pump adjustment knob (optional) the chain lubrication can be adjusted as shown in the illustration (fig.1), according to the type of cutting operation in hand (dry wood – more oil, green wood - less oil, long bar- more oil, short bar - less oil). Take great care to ensure that the chain is always sufficiently lubricated by never closing the pump completely. Refer to “Maintenance” for indications on ensuring that the chain oil is sufficiently distributed. Choice of chain oil Always use new oil only (special type for chains) with adequate viscosity: the oil must adhere well and guarantee good running properties in both winter and summer. If chain oil is not available, EP 90 transmission oil can be used. Never use waste oil because this is this harmful to health, the machine and the environment. Make sure that the oil is suitable for the temperature of the environment where the tool will be used: For temperatures under 0°C certain oils become denser, overloading the pump and causing damage. Contact your Authorised Service Centre for advice on oil choice. Filling oil tank Unscrew the oil tank cap, and fill the tank taking care not to spill any oil (if this occurs clean the machine carefully) (fig.2), and then screw the cap back on tightly. G. MAINTENANCE 1,2,3,4,5,6,7,8,9,12,13 ATTENTION! In cases where work environments are particularly dirty or dusty, ...
