Motor or control is damaged. Consult a  DINO-POWER authorized retailer, distributor, or service center.

 

Problem Cause Solution
Sprayer runs, but pump does not prime or looses prime while in use.

(Pump cycles but does not pump paint or build pressure.)

Inlet valve check ball is stuck. Press PushPrime button to dislodge the ball allowing pump to prime properly.
Prime/Spray valve is in SPRAY position. Turn Prime/Spray valve down to PRIME position until paint exits drain tube. The pump is now primed.
Pump was not primed with flushing fluid.

(Thick fluids may not prime if not initially primed with flushing fluid.)

Remove suction tube from paint. Prime pump with oil or water-based flushing fluid.
Debris in paint. Strain the paint.
Thick or “sticky” paint. Some fluids may prime faster if the ON/OFF switch is momentarily turned off so the pump can slow and stop. Turn ON/OFF switch on and off several times if necessary.
Inlet strainer is clogged or suction tube is not immersed in paint. Clean debris off inlet strainer and make sure suction tube is immersed in paint.
Inlet valve check ball or seat is dirty. Remove inlet fitting. Clean or replace ball and seat. 
Suction tube is leaking. Inspect suction tube connection for cracks or vacuum leaks.
Outlet valve check ball is stuck. Unscrew outlet valve, remove, and clean assembly.
Prime/Spray valve is worn or obstructed with debris. Take sprayer to DINO-POWER authorized service center.
Problem Cause Solution
Pump is primed, but can not achieve good spray pattern. Spray tip may be partially clogged. Clear spray tip clog.
Reversible spray tip is in UNCLOG position. Rotate arrow-shaped handle on spray tip so it points forward to SPRAY position.
Debris in paint. Strain the paint.
Pressure is set too low. Align pressure control knob setting indicator to desired spray setting.
Spray gun fluid filter is clogged. Clean or replace gun fluid filter.
Spray tip selected is too large for capability of sprayer. Replace tip.
Spray tip is worn beyond the capability of sprayer. Replace tip.
Spray tip gasket and seal worn or missing. Replace gasket and seal.
Inlet strainer is clogged or suction tube is not immersed in paint. Clean debris off inlet strainer and make sure suction tube is immersed in paint.
Extension cord is too long or not heavy enough gauge. Replace extension cord.
Inlet pump valve or outlet pump valve is worn or clogged with debris. Check for worn or contaminated inlet valve or outlet valve.

– Prime sprayer with paint

– Trigger gun momentarily

– When trigger is released, pump should cycle momentarily and stop

– If pump continues to cycle, pump valves may be worn or contaminated with debris

– Clean and reinstall valves

 

Material is too thick. Thin material. Follow manufacturers recommendations.
Airless hose is too long (if extra section was added). Remove section of airless hose.
Spray gun stopped spraying while trigger is pulled. Spray tip is clogged. Clear spray tip clog.
Sprayer lost prime. See troubleshooting section “Sprayer runs, but pump does not prime or looses prime while in use.”

 

Problem Cause Solution
When paint is sprayed, it runs down the wall or sags. Material is going on too thick. Move gun faster.
Choose a spray tip with smaller hole size.
Choose spray tip with wider fan.
Make sure gun is far enough from surface.
When paint is sprayed, coverage is inadequate. Material is going on too thin. Move gun slower.
Choose spray tip with larger hole size.
Choose spray tip with narrower fan.
Make sure gun is close enough to surface.
Fan pattern varies dramatically while spraying. Pressure control switch is worn and causing excessive pressure  variation. Take sprayer to DINO-POWER authorized service center.
Cannot trigger spray gun. Spray gun trigger lock is engaged. Rotate trigger lock to disengage trigger lock.
Paint is coming out of pressure control switch. Pressure control switch is worn. Take sprayer to DINO-POWER authorized service center.
Paint is leaking through drain tube. Sprayer is over pressurizing. Take sprayer to DINO-POWER authorized service center.
Paint leaks down outside of pump. Pump packings are worn. Replace pump packings

 

Motor is hot and runs intermittently. Motor automatically shuts off due to excessive heat. Damage can occur if cause is not corrected. Vent holes in enclosure are plugged or sprayer is covered. Keep vent holes clear of obstructions and overspray and keep sprayer open to air.
Extension cord is too long or not a heavy enough gauge. Replace extension cord.
Unregulated electrical generator being used has excessive voltage. Use electrical generator with a proper voltage regulator.
Motor needs to be replaced. Take sprayer to DINO-POWER authorized retailer, distributor, or service center.
