Spraying

1. Engage gun piston safety lock.

2. Close gun fluid manifold valves A and B.

ti2728a

3.Attach gun fluid manifold. Connect gun air line. Open air line valve.

ti2543a

4. Set PRESSURE RELIEF/SPRAY valves (SA, SB) to

SPRAY .

SA

SB

ti9877a

5.Check that heat zones are on and temperatures are on target, page 25.

6.Press motor to start motor and pumps.

7.Check fluid pressure display while the gun is detrig- gered and adjust as necessary, page 26.

8.Check fluid pressure gauges (GA, GB) to ensure proper pressure balance. If imbalanced, reduce pressure of higher component by slightly turning PRESSURE RELIEF/SPRAY valve for that compo- nent toward PRESSURE RELIEF/CIRCULATION

, until gauges show balanced pressures.

GA	GB
	In this example, B side
	pressure is higher, so
	use the B side valve to
	balance pressures.
