Preventive Maintenance

Schedule

The operating conditions of your particular system determine how often maintenance is required. Establish a preventive maintenance schedule by recording when and what kind of maintenance is needed, and then determine a regular schedule for checking your system.

Replace lens covers on regulator gauge lenses when dirt makes gauges difficult to read.

Tighten Threaded Connections

Before each use, check all hoses for wear or damage. Replace as necessary. Check that all threaded connec- tions are tight and leak-free.

Flush the Pump

Read all Warnings. Follow all Grounding instruc- tions. See page 11.

Flush the pump:

Before first use

When changing colors or fluids

Before repairing equipment

Before fluid dries or settles out in a dormant pump (check the pot life of catalyzed fluids)

At the end of the day

Before storing the pump.

Flush at the lowest pressure possible. Flush with a fluid that is compatible with the fluid you are pumping and with the wetted parts in your system. Check with your fluid manufacturer or supplier for recommended flushing fluids and flushing frequency.
