Fluid Supply

Fluid Supply - Shut off the air supply to the pressure tank.   Disconnect the pressurized adhesive supply hose at the applicator valve assembly.   This hose may be under pressure, so loosen the fitting slowly.  Place the end of the hose over a small container.

Then turn the air pressure regulator at the top of the tank slowly CLOCKWISE until:  A) the gage indicates 20 PSI and there is no flow from the home, or B) adhesive flows from the hose.  If "A" occurs and there is no flow, then turn the tank air supply off and depressurize the tank.  Turn the valve at the bottom of the tank off and then check the condition of the filter inside the brass T-body.   A plugged filter will prevent adhesive flow.  Remove the filter and clean with water and a small brush.  If this action will not clean the filter, replace it with a new one.  Refer to drawing 600 which lists the three available filter element. 

If "B" occurs and there is adhesive flow, then refer to:  TROUBLESHOOTING APPLICATOR VALVE ASSEMBLY.
Applicator Valve Assembly - Shut off the air supply to the control panel and pressure tank.  Disconnect the two 1/4" air control lines to the adhesive valve (see "Air Controls" for instructions on disconnecting air lines from quick-release fittings).  Hold the ends of the control lines in your hand.                                                                                                          

Reapply air to the control panel.  Air should exhaust from the "OFF" B line.  Flip the "TEST/FLUSH" switch upward to the "FLUSH" position.   Air should now exhaust from the "ON" A line to the valve.  

If air still exhausts from the "OFF" line when the "TEST/FLUSH" switch is flipped upward, then proceed with TROUBLESHOOTING ELECTRICAL CONTROLS.
Reconnect the air lines to the adhesive valve.  Reapply air to the control panel and pressure tank. 

Now flip the "TEST/FLUSH" switch upward to the "FLUSH" position.  The applicator valve should now open and adhesive should flow from the finger ports of the applicator head. 

If no adhesive appears at the applicator head then the APPLICATOR VALVE must be taken apart and serviced.   

Start the lug chain drive and run a few wood joints.  The applicator valve should open each time a wood joint passes through the sensors beam.  

If the applicator valve doesn't open as the wood joints pass, then proceed with: TROUBLESHOOTING
