Prime the System
1. Fill the hopper (J) with the prepared texture
material.
2. Install a tip. Refer to the Tip Selection Chart on
page 10.
3. Open the gun air valve (423) to be sure air pres-
sure is relieved and then close it again; the system
primes easier if no air is supplied to the gun.
4. Be sure there are no kinks in the hose, which
restricts fluid flow.
NOTE: If spraying a simulated acoustic and coarse
aggregate material, disconnect the hose at the gun,
prime the pump and hose, and circulate material back
into the hopper for 10 seconds. Turn off the pump.
Install the gun and tip.
5. Turn the ON/OFF switch (D) ON. Trigger the gun
into a pail. When texture material appears at the
tip, move the gun to the hopper and circulate until
there is a solid stream of texture material.
6. See SPRAY TECHNIQUES on pages 10 and 11
for how to balance the pump and gun adjustments
for a good spray pattern.
