Figure 8.k - Cut and hold knife adjustment and removal
The cut and hold knife blade condition is very important for the proper operation of the
cut and hold system. A blunt blade may not cut the film cleanly or possibly not at all. As
such, the knives must be changed under part number CKN00011. Ensure all safety
precautions are taken before carrying out the procedure on the following page.
Change the cut and hold knives by following the procedure and referring to Figure 8.k:
1. Loosen the two M6 setscrews that hold the knife clamp plate (B) in place using
a 10 mm spanner or socket, beware of knife blade!
2. Remove used knife, noting that there is a spare knife blade held by the bottom
of the knife clamp plate (B).
WARNING: Beware of knives & accumulators during maintenance
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 (See
figure 8.k), 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.
