Replace or tighten as required).

2.Piston seals (ref# 91) worn. (remove and replace piston seals, following closely the detailed instructions on page 24-25).

CORRECT STATIC PRESSURE, BUT REDUCED SPRAYING PRESSURE (Check with pressure gauge, see page 16 for details).

1.Spray tip worn out/too large. (replace with new, correct sized spray tip. Tip most not exceed a newer condition .031 tip (for 1 gun) or .021 tip (for 2 guns)).

2.Paint hose incorrect. (replace hose with genuine H.E.R.O. airless spray hose (min. 50 feet). Steel braided hoses must not be used ).

3.Intake valve seat (ref# 13) worn. (replace intake seat closely following detailed instructions on page 23).

4.Intake ball (ref# 14) worn. (replace intake balls when signs of wear, deformation, nicks or cuts are evident. An out of round ball is the sign of a worn intake seat,(ref# 13), and both items should be replaced).

5.Outgo seat (ref# 29) worn. (replace seat).

6.Outgo ball (ref# 30) worn/damaged. (replace outgo ball).

7.Prime valve (ref# 36) bypassing. (start sprayer. With prime valve closed tightly, stem,(ref# 46), turned clockwise fully, check prime valve return hose, (ref# 51), for material bypass. Repair prime valve using, (ref# 42), if material is bypassing.

LOW STATIC PRESSURE, LOW SPRAY PRESSURE (Check with pressure gauge, see page 16 for details).

1.Pressure control valve stem screw (ref# 80) loose. (remove pressure control knob,(ref# 75), and inspect screw for looseness. Screw should be secured to stem, (ref# 80), with Loc-Tite. If the screw turns independent of the stem than it must be re-secured. Secure unit so it will not move. Install pressure gauge and .021 spray tip. Obtain a piece of wood, to use as a pusher or purchase a pressure control adjustment tool, 27C-15. Remove pressure control screw and put some Loc-Tite 609 on threads. Turn the screw into the stem a few turns and push it in to its maximum and read pressure. Turn the screw in or out until 3000 psi static pressure is obtained. If you obtain a pressure which higher than 3000 psi, trigger gun to release some pressure and continue adjusting screw until correct pressure is obtained. Let Loc-Tite set up.

2.Pressure control ball (ref# 88) and/or seat (ref# 87) worn. (remove entire pressure control valve,

(ref# 74), from sprayer. Remove valve seat, ball, retainer,(ref# 86), and spring,(ref# 85), from valve. Replace with pressure control repair kit,(ref# 89). Hold valve body vertical while placing in spring, followed by retainer. Retainer should be below the valve body (approx. 3/8") when positioned correctly. Center ball on retainer, turn valve seat into body until finger tight, using pipe dope or Teflon tape to seal. Fully tighten using wrench.
