3. Changing and Storing Needles
Purpose
Needles are changed to correspond to different production programs or a needle may be
replaced when a nozzle becomes clogged.
Procedure
Removal
1. Use the inching operation to inch the syringe head to the center of the machine
where it is easily accessible, then press the EMERGENCY STOP button and cut the
power to the machine.
2. Turn the cap nut clockwise as viewed from above and remove it.
3. Remove the syringe assembly from the head as described below.
(1) While pressing the head down with one hand to keep the glue-level check
sensor out of the way, use the other hand to lift the syringe fixing ring
(black) several millimeters. (Lift until the ring's lock pins detach from the
syringe tab.)
Note: The syringe fixing ring is held onto the syringe holder by a magnet.
(2) Rotate the syringe assembly leftward 90 degrees, then pull the assembly
upward to remove it from the syringe holder.
Note: While lifting the syringe assembly, use one hand to push upward on the
needle side to prevent the adaptor from dropping off.
