FAQ: ARE THE CAP ASSEMBLY PINS SUPPOSED TO FULLY ENGAGE THE CARRIAGE
PLATE “EARS”?
The pins slightly engage the two carriage plate “ears”. The pins may not necessarily engage fully
when the machine is new. As the carriage plate wears and with cartridge variation, the pins will
engage the ears deeper. The third pin
must
face the operator and is only used to
hand tighten
the
cap into the carriage plate.
Do not tap on the third pin with a hammer or other tool. This may
damage or break the carriage plate.
The motion of mixing a cartridge naturally tightens the
cartridge into the carriage plate. The cap assembly is only used to keep the cartridge in place and
from rotating. If the material is highly viscous, you may need to adjust the regulator on the back of
the Model AC-900 Automatic Mixer to slightly increase the air pressure to hold the plunger in
place. If required, we recommend increasing in 2 psi increments until the proper pressure is
achieved. This varies based upon materials, but 10-12psi should be sufficient for most materials.
(To adjust, see step #8 above)
