Operation

10. Remove gun trigger safety latch. Trigger gun.
Roll surface.
NOTE: Trigger the gun briefly only when you need
more paint. Determine how often you must trigger
the gun to maintain an even paint supply to the
roller.
The best operating pressure is the lowest pressure
that provides an even paint supply to the roller and
typically does not exceed 300 psi (2.1 MPa, 21
bar).
11. Increase pump pressure only if triggering gun
cannot supply enough paint for your rolling speed.
12. Whenever you stop painting, relieve the
pressure, and elevate roller end of extension tube
to prevent paint from draining out.
Flush the pump, gun, and pressure roller immediately
after each use to prevent paint from drying in the
pressure roller and damaging it. (Cleaning, page 6).
