NOTICE
The gun assembly is secured inside
the air tube by a spring-loaded jacking
screw. It is spring loaded in order to control the force it
can impose on the gun assembly. When installing the
jacking screw look inside the air tube to verify that the
pointed tip of the jacking screw pin is seated into the
small slot on the locating pad on top of the gun. There is
also an external verifi cation of correct assembly: when
the screw is fully tightened, the e-clip on the top of the
center pin should come fl ush with the top of the screw.
Refer to Figure 3.
