Electronic Traction Control - Prinoth BISON Operating And Maintenance Manual

Snow groomer BISON
If vibrations occur in the cable during winch operation, stop them by adjusting the engine speed
or reducing the vehicle speed.
Watch the cable whenever you turn the snow groomer or raise the attachments. When the winch
arm is turned automatically when the direction of travel changes, it can collide with the attach-
ments if they are raised or turned.
Before changing the direction of travel, determine which way the snow groomer has to be turned.
Do not carry out repeated turns in the same direction.
Check if the cable is winding onto the drum correctly; if not, unwind as much cable as necessary,
then rewind.
If the cable slips off, do the following:
► Immediately switch off the snow groomer and AUTOMATIC winch and press the manual cable
unwind push-button switch <A37/6>.
► Call up the cause of the malfunction on the display and eliminate it.
► Check whether the cable has been damaged. If you are not sure, consult qualified personnel.
If the winch is blocked and no longer works, do the following:
► Deactivate winch operation.
► Move the vehicle toward the mount point until the cable is loose.
► Go to the mount point and unhook the cable.
► Bring the anchoring hook to the vehicle.
CAUTION
Risk of injury
If the anchoring hook is brought to the vehicle, the cable can slip and injure the person who brings
the hook.
► Always make sure that, during transport, the anchoring hook is located between the vehicle and
the person who is carrying the hook.
► If the cable slips, let go of the anchoring hook.

When the AUTOMATIC winch is mounted, vehicle speed is not reduced until the winch operation
push-button switch is pressed.
Cable traction force depends on the winch arm's swivel angle.
Starting from an angle of 30° from the vehicle longitudinal axis, cable traction force is progressively
reduced, until it reaches the minimum of 50 % of the preset traction force when the winch arm is at
right angles to the vehicle's longitudinal axis.
This system controls the cable traction force in such a way that the required force is delivered auto-
matically in all operating conditions. The "drum" symbol lights up continuously green on the display.
