The tension acting on the hose can be minimized by turning the red ring (Fig. 39, top right) clock- wise so that the suction nozzle presses against the pressure plate (I, Fig. 39).

•Check that the anti-roll guide is parallel and correctly adjusted. Readjust if necessary (see page 58).

•Activate trimming mode.

•Select the trimming thickness.

•Switch on the VAC and select a low extraction level (between 1 and 2).

•Start trimming by manually moving the handwheel or press the RUN/STOP and ENABLE keys simultaneously to start motorized sectioning.
