TROUBLESHOOTING
CAUTION: Stop using the tool immediately if any of the following problems occur or risk serious
personal injury. Repairs and replacements should only be performed by authorized personnel at a
certified WEN service center.
Problem Common Causes Solution
Air leaks from the regulator. Regu-
lator does not regulate pressure any
more.
The regulator has become damaged
or dirty.
Replace the regulator/internal parts.
Low PSI pressure and/or compres-
sor does not stop.
1. Tank drain valve is open.
2. Leaks in the unit.
3. Using too much air
4. Air intake obstructed.
5. Compressor is too small.
6. Blown gaskets or seals or leaking
valves or piston rings.
1. Close the drain valve.
2. Check the unit for leaks (see
“Testing for Leaks” on page 8).
3. Use less air.
4. Make sure the unit is away from
the wall and that the air inlets are
not obstructed.
5. Check the requirements of the
pneumatic tool. Make sure the
specifications of this compressor
meet the requirements.
6. Replace necessary parts.
A large drop in the regulated pres-
sure gauge occurs once a pneumatic
tool or other air accessory is being
used.
The compressor is too small. Check the requirements of the
pneumatic tool. Make sure the
specifications of this compressor
meet the requirements.
Motor won’t run. 1. Tank pressure is too high.
2. Motor overload protection has
been tripped.
3. Power source isn’t working.
4. Check valve stuck open.
1. Motor will start automatically
once the tank pressure drops.
2. Let the motor cool down for a
few minutes to reset the overload
switch.
3. Examine the power source. Make
sure that your extension cord is a
high enough gauge.
4. Clean or replace the check valve.
Pressure relief valve opens. Either the tank pressure is too high
or the pressure switch is stuck.
Replace the pressure switch.
