Initial Fill If an empty/new rechargeable transfer head is to be used prior to printing. The
transfer head unit is to be initially charged in accordance with the following:
1. Ensure the empty transfer head is fitted with a base cover.
2. Using the recharging gun (mastic or pneumatic gun). Load a standard
cartridge and fit the long recharging nozzle to the cartridge.
NOTE
To prevent air bubbles, ensure that the long nozzle is charged with paste
prior to carrying out the next Step.
3. Starting at one end of the unit, remove the filling hole bayonet cap and insert
the recharging nozzle into the unit, (figure below refers).
4. Start filling the cavity, at the same time push the diaphragm down with
fingers (Step 3 Figure refers), to feel the paste filling the void. Whilst the
paste is filling, gently knead the diaphragm to evenly distribute the paste and
also prevent ballooning. Fill approximately one third the length of the unit.
On completion remove the nozzle and refit the bayonet cap.
