Wire rope unwinding

When the winch is properly connected, we can begin with unwinding of the wire rope.
On tractors without a socket with constant current of 12 V, we can connect a supply
cable in the socket, which is usually made for connection of light equipment on the trailer.
Because of this, we have to turn on the position lights.
On the steering console (figure 8), press the left button to release the brake. Hydraulic
cylinder shifts to position 1. If we disengage pressure on the button in less than 3 seconds,
the brake cylinder shuts and the winch is again open and unwinding is not possible. If this
button is pressed for more than 3 seconds, the function shifts from "impulse" to "constant
release" and despite not holding the button, the cylinder stays in the open position and
the winch in unwinding function.
When unwinding, we have to be careful not to unwind the wire rope completely or leave
at least three winds on the drum. This distance is marked on the wire rope. Due to safety
reasons, the wire rope is installed on the drum so that if the logs start to slide without
control, the rope must "pull" itself off the drum. If the rope was pulled out with excessive
force, we can pull out the entire wire rope during pulling. In this case, replace it according
to the procedure, foreseen for wire rope installation.
If the wire rope is very tight and we wish to release it, we have to do it impulsively with
quick presses 2-3 times on the left button. This prevents the wire rope to unwind too quickly
from the drum and that the wire rope is not too loose. It also prevents the logs to slide
downhill.
Warning
Steel rope must be completely unwound before first use and wind it back on the
generator drum under load.
For instance, we can do this so that we attach the rope to a standing tree and pull the
tractor with slight braking to the tree. This procedure must be done also before trying to
tow, if we towed downhill beforehand or if the rope was wound loosely during towing.
ATTENTION!
Loosely wound steel rope can be damaged (stuck, bent) at greater load, so that it is
prohibited to use it again.
Warranty does not apply for a steel rope, which is damaged in such manner.
