Manual TwinSaw CDC double cut saws

The fitting sequence used for new blades is the reverse of the dismantling procedure. All
bolts should be done-up handtight. Do not overtighten.
7.2 Quick-release system Ø 310 mm
Machine: CDC 2530
Remember that carbide teeth are extremely sharp.
Always wear gloves when undoing and tightening
Before your hands are near the teeth or even the blades:
REMOVE THE POWER PLUG!
Lay the machine on its side! Remove the main nut using the
special tool or a 19 mm wrench.
The blades have to be locked into position by using the lock-
button or inserting the blade of a screwdriver through two aligned
holes to prevent movement.
Remove the outer blade system (saw blade and adapter) from its
shaft and withdraw the blade from beneath the safety cover.
Remove the blade from the adapter by opening the screws a bit
and turning around the blade. When the heads of the screws
have reached the end, you can depart the blade from the adapter
easily.
Examine both adapters (outer adapter shown in Figure) and
ensure that the springs are properly seated on the lock-button.
Wipe the adapters with a clean cloth, if necessary. The fitting
sequence for the new blades is the reverse of the dismantling
procedure.
7.3 Change from CDC 2530 to Training set CST 225
When you have lift off both blades, open the four screws beside the inner adapter, which
hold the hood.
Get the small hood 235 out of the Training set and fix it with the screws to the machine.
After that the outer flange has to be changed, because the training blades do have the
screwed system without bayonet plates.
Fix the small blades onto the adapters and make sure that the screws are fixed tightly.
Then begin operations as usual.
