Lubrication

CAUTION

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 Procedure on page 10 before storing it for any length of time. Use a compatible flushing fluid.

Tightening Threaded

Connections

1.Before each use, check all hoses for wear or dam- age, and replace as necessary.

2.Check to be sure all threaded connections are tight and leak-free.

3.Check and re-torque all screws and fasteners at least every two months.

Preventive Maintenance

Schedule

•Establish a preventive maintenance schedule, based on the service history of the pump. This is especially important for prevention of spills or leak- age due to diaphragm failure.
