If the motor runs below 10 psi air input pressure, it may be due to a missing or damaged spring loaded detent (113-NXT145). Replace the spring loaded detent (113-NXT145). Note: 20 psi (140 kpa, 1.4 bar) or greater is needed to run the NXT air motor.
What causes air continuously exhausting from the motor shaft on my Graco N22DT0?
Continuous air exhausting from the motor shaft indicates a damaged air motor shaft seal. Replace the seals with NXT200 (2200), NXT300 (3400), or NXT600 (6500) motor seal kit.
What causes continuous air exhausting from the muffler on up and down strokes in Graco N22DT0 Engine?
Continuous air exhausting from the muffler on up and down strokes is caused by the de-icing control being open. Close the de-icing control with the knob or a flat blade screwdriver.
Why does the Graco Engine motor run at 20 - 50 psi (140-345 kPa, 1.4-3.4 bar), but stops if input air pressure is 50 psi (345 kpa, 3.4 bar) or greater?
If the motor runs at 20 - 50 psi but stops if the input air pressure is 50 psi or greater, it's because two bumpers (59-277366) are installed below the #4 main piston. Remove the extra bumper (59-277366).
Why doesn't the Graco Engine runaway error code clear?
The runaway error code may not clear because the solenoid pin will not retract. Replace the solenoid (140-NXT403).
What causes air pressure to vary 5 - 10 psi from the set point on a Graco N22DT0?
If the air pressure varies 5 - 10 psi from the set point, the pilot valve (17-NXT095) bleed orifice may be obstructed. Rebuild it with regulator repair kit (17-NXT095).
