How to Troubleshoot Pneumatic Controls
The variety of machines that use forced air through pneumatic controls is extensive. Hammers, drills, nail guns and staplers are just a small sampling of tools that may use pressurized air or gas to work at high, efficient speeds. Many hot tub spas also use pneumatic air to regulate the flow of water inside the spa. Whether pressurized by gas or air, adequate voltage levels, secure connections, and unobstructed lines or hose pathways are needed for optimal function of pneumatic controls. Does this Spark an idea?

Verify that the air hose is not bent. If it is, turn off the machine and disconnect it from the power source. If your machine uses pressurized gas, stop here and contact a qualified technician; otherwise, wait until the motor stops and the machine is cool and then straighten out the air hose.

Inspect the motor-to-air hose connections and tighten if any are loose. Otherwise, the pneumatic force will be reduced since the motor powers the air hose.

Check voltage levels. Pneumatic devices require enough power to run. Refer to your machine's owner's manual for the minimum voltage level requirements. Contact an electrician for safe modifications to any circuits.

Tips & Warnings
Always adhere to safety guidelines when working with pressurized gas or air pneumatic controls. When in doubt, seek the advice of a professional, qualified technician.
If the reset switch for the ground-fault circuit connector (GFCI) is not in the downward position (tripped), a live electrical current could be present. Contact an electrician immediately to prevent injury or fatality from an electrical shock.
