• Using two wrenches, loosen the counter-nut “C” and
completely unscrew both the counter-nut and nut
“D”;
• Take off the track “E” starting from the anterior part;
• Mount the new track lining it up with the teeth in the
drive wheel “F”;
• Fit in the anterior part of the track onto the neutral
wheel “G”;
• Register the tension by working on nut “D”;
• Check that the arrow is at 30mm;
