Every 50 hrs
Register the tension of the tracks.
The correct ten-

important in order to
guarantee their lon-
gevity and for your
own safety: to check
it, apply a pressure
of 5 kg on the track
and check that the
arrow is at about
30mm.
To carry out the regulation of the tension of the tracks
correctly:
• Take off the cover “B” by unscrewing the two screws “A”;
• Using two wrenches, loosen the counter-nut “C”;
• Regulate the tension by working on nut “D”;
• Check that the arrow is at 30 mm;
• When you have finished regulating, block the counter-
nut;
• Put the cover back on;
• Repeat the same procedure on the other track.
