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).
SPRAY PATTERN IS SPOTTY OR UNEVEN
1.Pressure is too low. (increase pressure slowly until problem is corrected ).
2.Spray material too thick. (thin as recommended by material manufacturer).
3.Plugged: tank screen, intake tube, gun filter or a combination. (inspect and clean or replace as required).
4.Plugged tip. (remove and clean tip).
5.Pump malfunctioning or unsuitable for the material. (refer to other areas of troubleshooting guide and check material requirements vs 1100NC output abilities).
EXCESSIVE OVERSPRAY OR FOGGING
1.Pressure too high. (reduce pressure as required).
2.Material too thin. (follow material manufacturers recommendations
3.Tip too large. (reduce tip size).
4.Improper application technique. (refer to proper application techniques on page
