- Remove the cartridge that is on machine, and the top presser.
- Using the 3mm Allen key, loosen the locking screw of the wedge distributor Block H.
- Then lift the top presser’s bracket arm by hand. The wedge distributor will come out of its
housing.
- Remove it from the machine.
- The old hammer (wedge driver blade) is stuck in the wedge distributor : first try to remove it
with a pair of pliers. If not possible, remove the four screws (A, B, C, D) and open the block H.
(Two factory set locator pins E & F allow the plates to be re-positioned precisely again.)
- Remove the old hammer. Assemble the Block H back again.
Putting a new hammer (driver blade) :
- Put a drop of grease in the bottom hole of the wedge distributor (block H).
- Insert a new hammer into block H with the hole of the hammer downwards.
- Re-position the wedge distributor in its housing on the machine with the window towards the
cartridge.
- If the upper end of the hammer stays out of the block H, push it fully in with a piece of wood or
moulding.
While keeping the moulding in place (on block H) and pressing on it, pull up the top presser’s
bracket arm Po (Fig1 p1) with a quick movement.
The new hammer must have taken its position in the mechanism automatically.
- Check with your finger that the block H does not stay out of the machine (higher than the work
level) and tighten the locking screw of block H. No need to tighten too much.
- The machine is ready to work again.
