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, the operations described must be performed more frequently than mentioned in the instructions. Before each use Control that the chain oil pump functions correctly: direct the bar towards a clear surface at a distance of about 20 centimetres; after the machine has run for about a minute, the surface should show clear traces of oil(fig.1). Check that excessive strength is not needed for activating and deactivating the chain brake. Also check that it is not activated too easily and that it is not blocked. Then check chain brake function as follows: release the chain brake, grip the machine correctly and start up the machine, activate the chain brake by pushing the front hand guard forward with the left wrist or arm but without removing the hand from the handle(fig.2). If the chain brake is working correctly, the chain should be blocked immediately. ENGLISH – 7 Check that the chain is sharpened correctly (See below), in good working condition and that the tension is correct. If the chain is irregularly worn, or if the cutting teeth are only 3 mm high, the chain must be replaced(fig.3). Clean the air vents regularly to prevent motor overheating. Check that the switch and switch block function correctly (to be performed with the chain brake released): press the switch and the switch block and control that they return to idle position as soon as they are released; control that it is impossible to press the switch without activating the switch block. Check that the chain catcher and the right hand guard are in correct condition without any visible faults such as damaged material. Every 2-3 hours of use Control the bar condition, if necessary clean the lubrication holes(fig.4) and the guide grooves(fig.5) carefully; If the groove is worn or shows signs of deep notching, it must be replaced. Turn the bar to ensure even wear(fig.6). Clean the pinion regularly and check ...
