Crack

• If a crack appears between the track attach-
ment inserts, repair it if the length of the crack
reaches 60 mm. If the interior steel cable is ex-
posed, repair the track immediately even if the
crack is a small one.
• If the length of the crack is less than 30 mm
or if the depth of the crack is less than 10 mm,
you do not need to repair the track.

your YANMAR dealer.
