Precautions for operating the AUTOMATIC winch

CAUTION
Risk of injury
If damaged, the cable may rupture and cause injuries.
► Immediately inform specialised personnel of any irregularities found in the cable and have it
checked.
CAUTION
Risk of injury
There is a risk injury when handling the cable.
► Wear protective gloves.
► Only pull the cable by the anchoring hook; never pull the cable itself.
► Always keep the cable in front of you.
In order to ensure trouble-free operation, the following points must be considered before operating the
AUTOMATIC winch:
■ Take note of the operating conditions at the place of operation: snow conditions, snow layer prop-
erties, etc.
■ The AUTOMATIC winch should only be used on ski slopes that allow the snow groomer to stop
at the end of the slope. (For example, it is forbidden to work near sloping terrain).
■ The vehicle driver must be informed of the degree of difficulty if the piste being prepared.
■ The AUTOMATIC winch should only be operated by specially trained personnel.
■ It is strictly forbidden to carry passengers outside the driver's cab.
■ When operating the AUTOMATIC winch, the ski slope being prepared must be cordoned off; if
operated at night, the ski slope must also be fenced off and signposted.
■ The vehicle must not be driven under tensioned steel cables, ski-lifts or aerial cableways when-
ever the AUTOMATIC winch is mounted.
■ If the drum is still turning after being deactivated, switch off the engine immediately and check the
AUTOMATIC winch.
■ Exercise the utmost caution when tightening the cable, in order to prevent any jerking of the ca-
ble.
■ The cable may be unwound manually only when the engine is in low idle.
■ When pulling the cable taut, take care to prevent the middle of the cable from catching on or
winding around solid or sharp-edged obstacles (stones, rocks, etc.).
■ If the cable becomes entangled, stop tightening immediately, slacken the cable and check it for
damage carefully. If the cable is undamaged, you can start tightening again.
■ Check that the cable is correctly positioned and that the locking lever attached to the anchoring
hook is locked. All parts must be correctly anchored.
■ Before starting to use a newly installed cable, or directly after installing it, the cable should be
unwound at a low traction force all the way to the last coil, then rewound at maximum traction
force.
■ If the AUTOMATIC winch is not under power, no traction should be placed on the anchored cable
while the snow groomer is moving.
■ The loose cable must not be dragged over the snow.
■ When the winch arm is being tilted, it must be swung to the rear.
■ The tilted winch arm must always be properly fastened when tilted.
