Winch design data (see operating manual):
Engine group: M 3 Load spectrum: Q1 (L1) Factor of the load spectrum: Km = 0.125 Theoretical service life: D = 3,200 h
IMPORTANT: A general overhaul is to be performed every 10 years. For alternative provision, refer to section 5.4.2, p. 5 - 25. General overhaul performed on.......................................
