SCREW POSITIONS
If you have any difficulty to remove the block H from the machine, push down
with your hands the top presser’s bracket arm.This should free the block H that
is stuck with the hammer.
- 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, unscrew the two central screws (GF1, GF2) that hold the
fixed (square) guide of Block H in place. Use for this the smaller (2.5mm) Allen key supplied
with the machine. Remove the fixed guide completely to free the old hammer. If still not possi-
ble to get rid of the old hammer, remove the four screws (A, B, C, D) and open the block H.
- 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 or with a ruler 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.
