FLUID BEING SPRAYED OUT OF TIP PULSATES, SPRAY HOSE LIES QUIET WHEN GUN TRIGGER CLOSED

1.Spray tip worn out or too large. (replace with new tip of correct size. Tip must not exceed a good condition .023 tip ).

2.Paint hose incorrect type. (replace with genuine top quality H.E.R.O. airless spray hose. Steel braided hose is not recommended ).

3.Too short a length of hose. (minimum 50' of airless spray hose is required. Replace or add hose until a minimum of 50' is being used).

FLUID BEING SPRAYED OUT OF TIP PULSATES, SPRAY HOSE CONTINUES TO MOVE VIGOROUSLY WHEN GUN TRIGGER CLOSED

1.Outgo valve (ref# 32) assembled incorrectly. (remove the outgo valve and reassemble closely following the instructions on page 22).

2.Outgo valve ball (ref# 36) worn out or jammed. (inspect outgo ball to ensure that it is round and free of nicks or cuts. Inspect for foreign material jamming ball. Inspect seat and cage for wear. Replace parts as required).

PUMP SPRAYS WATER OR SOLVENT AT CORRECT PRESSURES, BUT WILL NOT SPRAY PAINT (Check with pressure gauge, see page 15)

1.Air leak in paint intake assembly. (check all fittings and hose clamps in intake assembly for tightness).

2.Air leak in paint intake. (check for cracked or broken intake fittings. Swivel connector, (ref# 11), or elbow,(ref# 13), may be damaged due to over tightening. Look for small black hairline fractures. Replace damaged parts).

3.Partial blockage in paint intake hose, (ref# 7). (clean and remove any blockages from intake hose. Check to insure strainer bag is not clogging intake hose).
