MACHINE SETUP
AIR FLOW CONTROLS
The heads, shuttles and door speeds can be affected by the air pressure on the system. There
are flow controls on all cylinders that can be adjusted to control the speed of all these actions. If
necessary to adjust, set the control so the action is smooth and not too fast, then lock the control
using the locknut.

PROXIMITY (REED) SWITCHES
There are reed switches mounted on the air cylinders for door closed, head up, shuttle forward
and back. These switches close when the cylinder is in its proper position and send that
information to the CPU. If a switch fails the machine will not function properly or not at all. To
check the switches locate the proper cylinder and observe the small LED mounted on each
switch. When properly aligned the LED will be on, if not, loosen the screw located on the switch
mounting bracket and move the switch until the LED lights. Tighten screw.
