Taking the winch out of operation for longer period

CAUTION
Risk of injury
If damaged, the cable may rupture and cause injuries.
There is a risk injury when handling the cable.
► Immediately inform the personnel responsible of any irregularities found in the cable and have it
checked.
► Wear protective gloves.
► Only pull the cable by the anchoring hook; never pull the cable itself.
► Always keep the cable in front of you.
NOTICE
Risk of contamination of drinking water
Cleaning agents can contaminate water resources.
► Cleaning agents, especially those used for cleaning the engine and mechanical and hydraulic
components, are to be disposed of in an environmentally responsible manner.
► Follow the legal provisions applicable to the place of operation
NOTICE
► Temperature range for storage: - 40 °C (- 40 °F) to + 40 °C (104 °F)
When preparing the AUTOMATIC winch for storage at the end of the winter season, or if it is taken out
of service for any extended period of time (more than 6 months), we recommend taking the following
steps:
■ In general, all advice on preserving the snow groomer as specified in the operating and mainte-
nance instructions apply.
However, it is advisable to take the following additional measures:
■ Clean the AUTOMATIC winch completely using a warm water jet and a suitable cleaning
agent, rinsing thoroughly. Then let dry. Have cleaning carried out by qualified personnel who
are aware of the possible hazards. Never wash the AUTOMATIC winch cable!
■ Unwind cable, clean it, and have it inspected as per DIN 15020/ Sheet2 by qualified and au-
thorised personnel.
■ Lubricate cable using a deep-penetrating preservative grease that contains a solvent and can
be easily applied with a brush (e.g. Shell 2722 or lubricating grease of similar quality).
■ Wind the cable onto the drum; check if rewinding works smoothly.
■ Apply preservative grease to the visible parts of the cable (drum, cable guide) once more.
■ Clean all guide pulleys.
■ Check the AUTOMATIC winch's attachment points and weld seams (AUTOMATIC winch
frame, winch arm, etc.) on the snow groomer frame.
■ Check the whole hydraulic system for leaks (firm seating and condition of hydraulic hoses,
valves, sockets, threaded connections, quick-lock couplings, etc.).
■ Make sure that all electrical consumers and alarm switches for the cable are functioning cor-
rectly.
■ Repair any damaged paintwork; rub silicon wax onto painted parts and apply a thin layer of
commercially available preserving agent to all metal parts.
