5. Actuate (open) the valves on the applicator(s) in order to fill them with adhesive and purge air from
the system.
6. Close the valves (those opened in the last step) to stop the flow of adhesive.
7. Using a wrench, turn the adjustment screw clockwise to increase the pressure to the applicator(s).
8. After desired pressure is achieved, stop turning the adjustment screw.
9. While the motor is operating at maximum speed and the applicators are valved on, observe the ad-
hesive flow from the applicator(s).
10. Reduce the motor speed, in increments of about 10%, until the adhesive flow begins to decrease.
Note: Though the speed of the motor is reduced, there will be no change in the amount of adhesive flow
coming out of the applicator. This is because the pressure relief is designed to allow only a maximum
adhesive pressure regardless of the motor speed past a certain point.
Then, increase motor speed in smaller increments (1 to 5%) until adhesive flow returns to the desired
amount.
Note: This is the optimum point of operation for the motor, pump and pressure relief. It will also facili-
tate the best system performance and reduce wear on these components.
The application system is now adjusted for normal operation.
CAUTION: Approach desired pressure with caution. Be aware that the higher the
adjusted pressure, the more sensitive the adjustment is (i.e., at higher pressures,
smaller adjustments to the screw will make larger changes to actual pressure).
