TROUBLESHOOTING
The Pump Will Not Generate Pressure
 Reason
The pump has probably lost its prime.
 Solution
If it will not prime, remove the reservoir and insert a small wire into the inlet check valve hole to make sure the valve moves freely. Squirt oil into the inlet
check valve while squeezing and releasing the handle. Then reinstall the reservoir and prime the pump. Another possible reason for pump failure is dirt under
one of the check valves, which may prevent fl uid from fl owing freely back into the reservoir. We recommend removing, cleaning, and reinstalling the check
valves. See the diagram below for proper check valve reassembly.
Outlet Check Valve Inlet Check Valve
The Pump Does Not Hold Pressure
 Reason
The pump may be leaking internally or externally.
 Solution
If pressure goes up when the handle is squeezed and drops when the handle is released, there may be dirt under the outlet check valve. Remove the brass
plug, clean the check valve, and reinstall.
