Storing the winch
NOTICE
Risk of damage to the hydraulic system
Strong solar radiation can cause the hydraulic fluid to heat up and by that damage the hydraulic sys-
tem.
Even the smallest particles of dirt or impurities getting into the oil can result in damage to the hydraul-
ic system.
►
Do not expose the AUTOMATIC winch to direct sunlight while detached from the snow groomer.
►
If solar radiation cannot be avoided, drain the oil from the return line.
►
AUTOMATIC winch not mounted: cover the quick-connect couplings with clean protective caps.
■
Store the AUTOMATIC winch in a dry and well-ventilated room with a roof, where it is not in
direct contact with the ground.
■
To protect the AUTOMATIC winch, cover it with an air-permeable tarpaulin.
