8.3 Blade replacement.
(fig.7)
Always wear cut-resistant gloves (EN 388:2003 version B= 5) and safety footwear when replacing the
blade or when working in the vicinity of the blade.
Some machines are equipped with an optional indicator that lights up when the blades need
replacing (fig.10, n°26).
Having ensured that the plug on your machine (fig.2, n°15) has been disconnected from the mains:
Open the door (fig.1, n°8).
A. Remove the bagging paddle.
B. Unscrew the front table at the sides of the machine.
C. Remove the front table.
D. Unscrew the cover.
E. Open the cover that protects the blade holder frames. On the upper part of the front frame,
remove screws A, which secure the frame to the polypropylene strips (never remove the strips
from the frame, as you risk altering factory settings).
F. Lay the frame down forwards. Replace the blades on the rear frame (place something to
protect yourself on the front frame blades). Remove the locknuts on screws B (Misch
machines). Remove the blade-tightening Allen screws B. Replace the blades, checking that
they locate correctly in the swing arm pins. Retighten the blades by tightening screws B, using
the blades remaining on the frame as a reference. Then tighten the nuts (machine fitted with
lubrication option).
In order not to distort the frame and avoid the risk of dangerous breakages, only replace 1 to 3
blades at a time alternating from left to right.
