8. Install the cap nut.

Notes:

If a head is not used during production, be sure to install an empty syringe (with

adapter attached) and the rotary joint to form an airtight seal. This will prevent air

from escaping and help to maintain the glue temperature.

After installing the needle and before operation, eject approximately 0.2 cc of glue through

the needle to drive out air trapped in the joint.

The syringes are disposable. Fuji recommends using the syringes twice. Further use will

wear down the ridges which are used to lock the syringe into place and the syringe may fall

from the holder.

Capacity: 30 cc/syringe

Material: Resin (plastic)

Glue volume: Approx. 30 cc.

The syringes are disposable.

The glue must be free of air.

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.
