What to do if the Graco SaniForce A air motor will not run?
If the air motor will not run, it could be due to a damaged air valve (17) or a damaged pilot valve (19). In the case of a damaged air valve, you should replace or service the air valve (17). If the pilot valves are damaged, replace them (19).
Why is air continuously exhausting from the Graco Engine muffler?
Continuous air exhausting from the muffler is often caused by a damaged air valve plate (105) or cup (112), or a damaged piston o-ring (8). If the air valve is the issue, replace or service air valve (17). If the piston o-ring is damaged, replace the seals.
Why is there icing inside the Graco SaniForce A motor?
Icing inside the motor can occur if 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. Additionally, reduce the dew point of the compressed air in the moisture coalescing filter.
What to do if the Graco Engine air motor “bounces” at the bottom of the stroke?
If the air motor “bounces” at the bottom of the stroke, it is likely due to a damaged top pilot valve. Replace the top pilot valve (19).
What causes the Graco SaniForce A air motor to “bounce” at the top of the stroke?
If the air motor “bounces” at the top of the stroke, a damaged bottom pilot valve is likely the cause. Replace the bottom pilot valve (19).
How to stop air continuously exhausting around the Graco SaniForce A air motor piston rod?
If air is continuously exhausting around the air motor piston rod, it is likely due to damaged u-cups (3, 33). You should replace the piston rod u-cups (3, 33).
