[. . . ] The gap between the guide bar and the tie strap of the saw chain should be approx. 2 - 4 mm, slightly turn the adjusting dial which secures the guide bar. Excessively high tension of saw chain may cause breakage of saw chain, wear of the guide bar and breakage of the adjusting dial. Installing or removing saw chain should be carried out in a clean place free from sawdust and the like. Before starting work, carry out the following checks: Checking the chain tension (Fig. 18) WARNING: · Always withdraw the mains plug before checking the chain tension, and wear safety gloves. The saw chain is correctly tensioned when it is in contact with the underside of the bar and can be raised approximately 2 - 4 mm from the bar by light finger pressure. Check the chain tension frequently, as new chains are subject to elongation. A chain which is too slack can jump off the bar, and therefore presents an accident risk. If the chain is too slack: Refer to the section titled "Adjusting saw chain tension" and adjust the saw chain tension again. It must not be possible to depress the switch trigger unless the lock-off button is first depressed. When released, the switch trigger must return automatically to the OFF position, and the lock-off button must return to its original position. Hold the rear handle with your right hand, the front handle with your left. With the saw running, hold the saw chain approximately 15 cm above a tree trunk or the ground. If lubrication is adequate, the oil spray will produce a light oil trace. Observe the wind direction, and do not expose yourself to the oil spray unnecessarily. Clean the oil feed groove and the oil feed hole in the bar (refer to "MAINTENANCE"). Carry out the cut as carefully as possible, as the serrated rail cannot be used. 26) - Before starting felling work, ensure that: (1) Only persons involved in the felling operation are in the vicinity; (2) Any person involved has an unhindered path of retreat through a range of approximately 45 ° either side of the felling axis. Consider the additional risk of tripping over electrical cables; (3) The base of the trunk is free of foreign objects, roots and ranches; (4) No persons or objects are present over a distance of 2 1/2 tree lengths in the direction in which the tree will fall. - Consider the following with respect to each tree: · direction of lean; · Loose or dry branches; · Whether or not the tree is rotten. 27) - Cut a scarf: The scarf determines the direction in which the tree will fall, and guides it. [. . . ] 37) Take the filter out of the chain saw and remove small dust or particles from it. 38) Pull the switch trigger to flow built-up dust or particles off the oil discharge hole by discharging chain oil. 40) Insert the push nut with its correct side facing up as shown in the figure into the oil discharge hole to secure the filter. When the filter cannot be secured with a disfigured push nut, replace the push nut with a new one. [. . . ]
