During Winch Operation - Prinoth BISON Operating And Maintenance Manual

Operating and Maintenance Manual
NOTICE
Opening the driver door
► If the driver door is opened during winch operation, the winch stays active and the traction force
is maintained.
This function is activated by pressing the winch operation push-button switch <A37/7>. The display
shows the "winch operation" symbol for 2 s.
The following conditions are required for winch operation:
■ Both doors must be closed.
■ The cable must be tensioned.
If the cable is not pulled taut, back the snow groomer slowly away from the anchoring point until the
cable is taut. The AUTOMATIC winch is ready for use once the cable is tensioned.
The system automatically sets the cable speed. The cable traction force is reduced automatically de-
pending on the relation between the winch arm of the AUTOMATIC winch and the direction of travel.
If the snow groomer is moved while the cable is anchored without first activating the winch operation
function, vehicle speed is reduced as soon as the angle sensor detects the cable tension signal. This
is indicated by a flashing winch operation symbol and an alarm sound. The winch operation push-but-
ton switch must then be pressed immediately to put the AUTOMATIC winch into operation.
After getting into and out of the cab, both winch operation and drive standby mode must be activated
again in order to continue operating the winch.
The display shows the "winch operation" symbol for 2 s.

During winch operation

Strictly observe the operating and accident prevention regulations mentioned above and the following
points during winch operation:
Monitor the display, especially during night operations and whenever the cable length between
snow groomer and the anchoring point is not directly in the driver's field of view.
If manual control is selected, set the cable traction force using the cable traction force potentiom-
eter on the joystick, taking the operating conditions into account.
Set the cable traction force in such a way that the tracks never slip so as to maintain stability and
manoeuvrability. Do not load the cable any more than the operating conditions require.
When driving on extremely steep slopes, keep the snow groomer in the direction of the slope in
order to maintain stability; drive slowly and don't turn.
