Why is air continuously exhausting from the muffler of my Graco Engine?
Continuous air exhaust from the muffler of your Graco Engine can occur if the de-icing control is open. To resolve this, close the de-icing control using the knob or a flat blade screwdriver. Alternatively, the air valve carriage, plate, or seal might be damaged, requiring you to replace the carriage, plate, or seal.
How to fix icing on the muffler of Graco Engine?
Icing on the muffler of your Graco Engine can be resolved by reducing the pressure, cycle rate, or duty cycle of the motor. You can also open the de-icing control using the knob or a flat blade screwdriver.
What to do if the air motor of my Graco Engine will not run?
If the air motor of your Graco Engine isn't running, it could be due to the DataTrak solenoid being engaged or damaged main air valve spool or poppets. In this case, rebuild the main air valve or replace the poppets. Another potential cause is a runaway, see Runaway on page 9.
Why is the motor reversal slow on my Graco Engine?
A slow motor reversal on your Graco Engine may be due to a plugged poppet muffler. Try removing the muffler and cleaning it.
Why is air continuously exhausting around the air motor shaft of my Graco Engine?
Continuous air exhausting around the air motor shaft usually indicates a damaged air motor shaft seal. Replace the air motor shaft seal to resolve this issue.
What causes the air motor to 'bounce' at the bottom of the stroke in my Graco Engine?
If the air motor 'bounces' at the bottom of the stroke, it's likely due to a damaged top poppet. Replace the top poppet to fix this.
What causes the air motor to 'bounce' at the top of the stroke in my Graco Engine?
If your Graco Engine's air motor 'bounces' at the top of the stroke, the bottom poppet is likely damaged. Replacing the bottom poppet should resolve the issue.
