5. Prepare each gun in your system for operation as follows:
S Air-operated guns: increase the operating air pressure to
240 kPa (35 psi).
S Electric guns: turn on the gun driver.
S Hand-operated guns: unlock the trigger.
WARNING: Trapped air may still be in the hoses and guns.
Shield the area and operator from splashing adhesive.
6. Trigger the guns, keeping them open so that no pressure builds up.
NOTE: You may need to adjust the gun air pressure depending on
the viscosity of the adhesive and the gun response.
7. Flush the system by using one of the following methods, depending
upon the type of pump your unit has (see Figure A 3-4).
Pump Type
Flushing Method
Piston pump If the PUMP light is not on, press the PUMP key.
Gradually increase air pressure to the pump by
turning the air pressure regulator clockwise. Allow
adhesive to flow out of the guns until all trapped air,
cleaning solution, and impurities are flushed out of
the system. If the pump slows noticeably or stops,
increase pump air pressure slightly.
Gear pump with
AC motor drive
Press the PUMP key and allow adhesive to flow out
of the guns until all trapped air, cleaning solution,
and impurities are flushed out of the system.
