PROBLEM POSSIBLE CAUSE(S) POSSIBLE ACTION(S)
Pump will not prime and Pump
motor is running.
1. There is a leak(s) in the suction
line.

process.

1. Follow the specifications in Section
4 to make sure the suction line
is installed properly and that all
fittings are 100% airtight.
2. Make sure the pump head is filled
with oil prior to starting the pump.
See Section 5.
3. Follow the procedure in Section
5 to fill the oil line and prime the
pump.
4. With the pump not running, wipe
your finger along the bottom of the
cylinder at the pump shaft. If there
is oil at the pump shaft, the seal is
damaged. Replace the pump, or
replace the seal.
NOTE: Some oils will expand as
they warm up. Because there is
a check valve in the suction line,
the expanding oil may build up
pressure and damage the oil seal.
Install a mini-accumulator in the
1/8” port of the canister filter to
prevent the pressure build-up.
5. Open the ball valve on the suction
line.
6. Refer to Section 9 to clean the
