To Next PageTo Next PageWhy is the Graco N22DT0 Engine runaway error code displayed and the pump running faster than the set limit?
The runaway error code appears and the pump runs faster than the limit because of an exhausted fluid supply, increased air pressure, increased fluid output, or a set point that is too low. To resolve this, first verify that the air pressure has been removed. Then, wait 30 seconds and press reset.
Why is air blowing out of the rear main motor exhaust on my Graco Engine?
Air blowing out the rear main motor exhaust indicates a worn or damaged motor piston o-ring. Replace the motor piston o-ring (17) to fix this. Use models: 2200 -123196, 3400- 122434, or 6500- 122675.
Why does my Graco N22DT0 motor run slow?
A slow-running motor can be caused by icing or an inadequate air supply. External icing is normal. Try reducing the pressure, cycle rate, or duty cycle of the motor, and/or turn the de-icing control knob (62-NXT112) counter-clockwise to open. Also, increase the air supply and remove any restricting connecting devices. The air line should be a minimum size of 3/4 inch.
What causes air to blow out of the rear main motor exhaust due to damaged valve plate seal (104-15F435) in Graco Engine?
If air is blowing out the rear main motor exhaust because of a damaged valve plate seal (104-15F435), you need to replace the valve plate seal (104-15F435).
What causes air to blow out of the rear main motor exhaust due to worn air valve cup/carriage (108-NXT138) in Graco N22DT0?
If air is blowing out the rear main motor exhaust, it may be due to a worn or damaged air valve cup/carriage (108-NXT138). Replace the air valve cup (108-NXT138) to resolve this.
How to fix slow motor reversal on Graco N22DT0 Engine?
Slow motor reversal is often caused by a plugged poppet muffler (58-120206) on the top cap plate (1), and/or a poppet muffler (58-120206) in the bottom motor cover (3). Replace the poppet muffler (58-120206) on the top cap plate (1), and/or the poppet muffler (58-120206) in the bottom motor cover (3-NXT302).
What to do if the Graco N22DT0 Engine built in air inlet gauge reads zero?
If the built-in air inlet gauge reads zero, it indicates a lack of air pressure. Verify that the air supply is present and the main air valve is on. Turn the 'C' regulator knob clockwise to the desired set pressure.
What to do if the poppet valve (12-NXT100) on my Graco N22DT0 Engine is leaking constantly through the poppet muffler (58-120206) exhaust?
If the poppet valve is stuck open and exhausting air through the muffler in mid-stroke, remove and clean the poppet valve. Ensure that the o-ring (12d) and back-up ring (12c) do not remain in the end cap castings prior to re-assembly.
Why does the Graco N22DT0 motor only run at 50 psi (345 kpa, 3.4 bar) or greater?
If the motor only runs at 50 psi or greater, it is likely due to a leaking flat gasket (46-253476). Replace the flat gaskets (46-253476), and apply grease to the gasket surface prior to re-assembly.
What causes air pressure to jump to line input pressure from the set point on a Graco N22DT0?
If the air pressure jumps to the line input pressure from the set point, it indicates that the formed gasket (17-15G439) is leaking. Replace the gasket (3-15G439) or seal repair kit (NXT096).
