The depth of the notch should be equal to about 1/4 of the diameter of the ENGLISH - 3 tree and the angle of the upper and lower cuts should be at least 45°. Main cut The main cut is made on the opposite side from the directional cut and must be perfectly horizontal, and at a height about 3 cm above the base of the directional cut (see illustration) Finish the cut at least 1/10 of the tree diameter from the directional notch. This is called the breakage line and serves to control the direction of fall of the tree because the tree will now start to fall. This can be facilitated using a crowbar on the main cut. Caution! If the breakage line is too small or is cut diagonally it will no longer be possible to control the direction of fall of the tree. F.

First file all the teeth on one side then turn the chainsaw and file the teeth on the other side • File in such a way that all the teeth are the same length. • When only 3 mm (1/8”) of the length of the cutting teeth remains, replace the chain. • FIG F4 file perpendicular to the bar plane (90°) • FIG F5 About every 5 sharpenings, check the cutting height against the cutting depth limiter (H). To reduce the height of the limiter use a caliber. • FIG F6 Every 3 hours of work remove the bar and clean the groove, make sure the oil outlet hole is not obstructed by chips and remove all sawdust deposits from the tool. Important: reverse the direction of installation of the bar every time you clean it so as to obtain uniform wear • FIG F7 Check frequently that the ventilation slots on the motor are free and the grating is clean.
