TROUBLESHOOTING

Possible Causes
For technical questions, please call 1-888-866-5797.
Likely Solutions
1. No problem. Compressor will start when needed.
2. Check that cord is plugged in securely.
3. Check that circuit matches compressor requirements.
4. Reset circuit breaker, or have outlet serviced by a qualified technician.
5. Turn off Compressor and wait for it to cool down.
Press reset button. Resume operation.
6. Reset circuit or replace fuse. Check for low voltage conditions.
It may be necessary to disconnect other electrical appliances
from the circuit or move the compressor to its own circuit.
7. Use larger diameter or shorter extension cord or eliminate extension cord.
See Recommended Wire Gauge for Extension Cords in Safety section.
8. Have unit inspected by a qualified technician.
1. Check that circuit matches compressor requirements.
2. Move compressor to a warmer location.
3. Listen for air leaking from valve.
If leaking, replace with identical valve with same rating.
DO NOT SEAL OR TAMPER WITH SAFETY VALVE.
4. Reduce air pressure, then check all fittings with a soap solution
for air leaks and tighten as needed. Do not overtighten.
1. Check inlet and outlet filters.
Clean and/or replace as needed.
2. Have technician clean or replace, as needed.
3. Check if accessory CFM is met by Compressor. If Compressor cannot
supply enough air flow (CFM),
you need a larger Compressor.
4. Reduce air pressure, then check all fittings with a soap solution
for air leaks and tighten as needed. Do not overtighten.
5. Replace with wider hose and/or hose connections.
6. Higher altitudes require compressors with greater output.
1. Check inlet and outlet filters.
Clean and/or replace as needed.
2. Clean and/or replace filters more often or
move unit to cleaner environment.
3. Eliminate extension cord.
4. Reposition unit on a level surface.
1. Reduce air pressure, then check all fittings with a soap solution
for air leaks and tighten as needed. Do not overtighten.
2. Check if accessory CFM is met by Compressor. If Compressor
doesn't reach accessory CFM, you need a larger Compressor.
1. Reduce air pressure, then check all fittings with a soap solution
for air leaks and tighten as needed. Do not overtighten.
2. Reposition unit on a level surface.
Install inline air filter/dryer, and/or relocate to less humid environment.
Pull on test ring of safety valve. If it still pops, replace.
Reduce air pressure, then check all fittings with a soap solution
for air leaks and tighten as needed. Do not overtighten.
Have tank replaced by a qualified technician.
Drain moisture from tank daily to prevent future corrosion.
