8.5 Cut and hold system
The cut and hold system on the machine is designed to operate in conjunction with both
the dispenser and table rollers to cut the plastic after a desired amount of film wrap has
been applied to the bale, as set on the control box. The cut and hold system operates
by way of a slider (D) that slides in and out using a hydraulic ram. The slider (D) then
clasps the film and retracts to hold the film between (C) and (D) which is then cut at
knife point (B). Once the wrapping process resumes, the film is then released.
Release hydraulic pressure from accumulators
WARNING: Beware of knives & accumulators during maintenance
The cut and hold system utilises knives and accumulators in order to
function. Beware of serious injury when carrying out any maintenance in
this area. Turn off the tractor and remove the key from the ignition. Wear
protective gloves and clothing, at all times! Also, never carry out any
work on the hydraulic hosing because even when the machine is off,
hosing remains under high pressure due to the
accumulators.
WARNING: Hydraulic accumulator is under high pressure
Before working on cut and hold rails, always release the hydraulic
pressure from accumulators by wrapping the spanner and hose-fitting
with a cloth, then slowly and carefully open the pressure hose fitting,
allowing oil to release before re-tightening. Accumulator pressure will
reset automatically following the first operation of the cut and hold
cylinder in the fully out direction. Never work on the cut & hold by holding
out the rails against hydraulic pressure.
