If air is continuously exhausting around the air motor piston rod of your Graco Paint Sprayer, it indicates damaged u-cups (207). Replace the piston rod u-cups (207).
What to do if my Graco Paint Sprayer pump operates but does not prime?
If your Graco Paint Sprayer pump operates but does not prime, it might be due to held open or worn ball check valves or piston packings. Try to clear the valve and replace the packings. Also, check the suction hose o-ring (38); if it's worn, replace it.
How to prevent icing inside the motor of my Graco Merkur ES Paint Sprayer?
If you're experiencing icing inside the motor of your Graco Paint Sprayer, it's likely because the air motor is operating at high pressure or a high cycle rate. To resolve this, reduce the pressure, cycle rate, or duty cycle of the motor. Also, reduce the dew point of compressed air in the moisture coalescing filter.
Why is the output low on both strokes of my Graco Merkur ES?
If your Graco Paint Sprayer pump operates but the output is low on both strokes, start by checking for any restrictions in the line, ensuring an adequate air supply, and verifying that the valves are open and not clogged. Additionally, inspect the fluid hose and gun for any obstructions, and make sure the fluid hose ID is not too small; clear any obstructions or use a hose with a larger ID. Finally, worn packings in the displacement pump can also cause low output; in this case, replace the packings.
What causes low output on downstroke of Graco Paint Sprayer?
If your Graco Paint Sprayer pump operates, but the output is low on the downstroke, it could be caused by ball check valves or piston packings being held open or worn. Clear the valve, and replace the packings.
Why is the output low on both strokes of my Graco Merkur ES pump?
If your Graco Paint Sprayer pump operates but the output is low on both strokes, the issue could stem from a restricted line, inadequate air supply, or closed/clogged valves. Ensure the line is clear, increase the air supply, and check that the valves are open. Another possibility is an obstructed fluid hose or gun, or a fluid hose with an ID that's too small. Make sure they are clear and consider using a hose with a larger ID. Finally, worn packings in the displacement pump can also cause this issue; if so, replace the packings.
Why is there icing inside the motor of my Graco Merkur ES Paint Sprayer?
If icing occurs inside the motor of your Graco Paint Sprayer, the air motor might be operating at high pressure or a high cycle rate. Reduce the pressure, cycle rate, or duty cycle of the motor. Also, reduce the dew point of compressed air in the moisture coalescing filter.
Why is air continuously exhausting from the muffler of my Graco Paint Sprayer?
If air is continuously exhausting from the muffler of your Graco Paint Sprayer, it is likely caused by a damaged air valve plate (305) or cup (312). Replace or service the air valve (214).
Why does the air motor of my Graco Paint Sprayer “bounce” at top of stroke?
If the air motor of your Graco Paint Sprayer “bounces” at the top of the stroke, this is due to a damaged bottom pilot valve (213). Replace the bottom pilot valve (213).
What to do if the air motor of my Graco Merkur ES Paint Sprayer will not run?
If the air motor of your Graco Paint Sprayer will not run, it could be due to a damaged air valve (214) or a damaged pilot valve (213). Consider replacing or servicing the air valve (214) or replacing the pilot valves (213).
