Maintenance

Lubrication

The air valve is designed to operate unlubricated, how- ever if lubrication is desired, every 500 hours of opera- tion (or monthly) remove the hose from the pump air inlet and add two drops of machine oil to the air inlet.

CAUTION

Do not over-lubricate the pump. Oil is exhausted through the muffler and could contaminate your fluid supply or other equipment. Excessive lubrication can also cause the pump to malfunction.

Flushing

To reduce the risk of serious injury, whenever you are instructed to relieve pressure, always follow the Pres- sure Relief Procedure on page 11.

Insert suction tube into cleaning solution. Open air regu- lator to supply low pressure air to the pump. Run the pump long enough to thoroughly clean the pump and hoses. Close the air regulator. Remove the suction tube from the cleaning solution and drain pump. Place suc- tion tube in the fluid to be pumped.

Flush the pump often enough to prevent the fluid you are pumping from drying or freezing in the pump and damaging it. Flushing schedule will be based on what the pump is being used for. Use a compatible cleaning solution and always cycle the pump during the entire flushing process.

Always flush the pump and relieve the pressure before storing it for any length of time.

Maintenance

Tightening Connections

Before each use, check all hoses for wear or damage, and replace as necessary. Check to be sure all connec- tions are tight and leak-free.

Preventive Maintenance Schedule

Establish a preventive maintenance schedule, based on the pump’s service history. This is especially important for prevention of spills or leakage due to diaphragm fail- ure.
