1. Changing a Syringe

Purpose

Replace a syringe when the glue runs out, or when a different type of adhesive must be

used.

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.
