Squeeze Out Adjustment - Once the applicator head has been correctly aligned, adhesive pattern adjustments can be performed.   The Apquip system employs a high speed optical sensor and solid state timers to insure a reliable, consistent adhesive pattern. 

Sensing Components Check - Before proceeding to adjustment, a quick check of the sensing electronics will verify that the system is set up correctly. There are three things to check:  

1.   Sensor Position   The sensor, for finger jointer applications, should be installed on the hold down section, the side opposite the cutter head. For edge  or face gluing, any location one inch upstream of the applicator head is suitable.  The aluminum body which houses the sensor should be installed as follows: 
1.)    It is preferable to place the sensor on the side of the hold-down section that is away from the cutter head.  This offers more protection from contact by the cutter head whenever it is removed. 

2.)    The beam centerline should be 1" or less UPSTREAM of the centerline of the applicator head.  The bottom edge of the sensor housing should be 1-1/2" above the wood surface.  This distance should be measured when the hold-down section is adjusted for a given thickness of wood. 

3.)  The 1-1/2" edge of the block should be parallel to wood travel.  The beam diameter is small enough so that it can be mounted with the beam located between the edge of the hold-down flex strip and the edge of the lug.

Main Switch on the face of the enclosure door, locate the "ON/OFF" switch.  Move handle to "ON" position. 
Manual Valve Switch on the face of the enclosure door, locate the "TEST/FLUSH" switch.  This switch has 3 positions:  up "FLUSH", down "TEST", and the center position for automatic running.   

Once the head has been aligned and the sensing components checked, dynamic adjustment (with the jointer running) can be made:  

1.) Bleed any trapped air out of the adhesive supply line using the "FLUSH" switch.  This switch overrides the sensing circuit and directly opens the applicator valve.

2.) Turn the "START" knob one turn or less CLOCKWISE and turn the "LENGTH" knob all the way CLOCKWISE. Start the lug chain drive.

These adjustments must be made with the jointer running. Slowly turn the "START" adjustment counter-clockwise to move the adhesive pattern to the leading edge. Then, slowly turn the "LENGTH" adjustment counter-clockwise to move the pattern to the trailing edge.

Note:   A small gap, or "spared" area, 1/16" - 1/8" should be left on both ends of the adhesive pattern to allow for a little squeeze forward/rearward of the adhesive during assembly.
To double check your adhesive pattern settings, examine an assembled wood joint farther down the line.   A very thin bead of adhesive or fine droplets squeezed out on top of the joint indicate a sufficient quantity of adhesive applied to the joint (i.e. correct adhesive pressure).

Squeeze-out on the edge surface of the joint should be eliminated.  To remove the edge squeeze-out, turn the "START" adjustment slightly clockwise ("later") and turn "LENGTH" adjustment slightly clockwise (shorter).  When these controls are correctly set, the adhesive pattern will be slightly less than the width of the joint, thereby allowing for a little squeeze forward/rearward of adhesive and preventing side squeeze-out.
