Maintenance

Lubrication

NOTICE

Lubrication of the pump is not required. Oil is exhausted through the muffler, which could contami- nate the fluid supply or other equipment. Excessive lubrication can also cause the pump to malfunction.

Flushing and Storage

Flush the pump often enough to prevent the fluid you are pumping from curing, drying, or freezing in the pump and damaging it. Follow the Pressure Relief Proce- dure on page 10 before storing it for any length of time. Use a compatible flushing fluid.
