Maintenance
Lubrication
The air valve is lubricated at the factory and designed to operate without additional lubrication.
If added lubrication is desired, every 500 hours of operation (or monthly), remove the hose from the pump air inlet and add two drops of machine oil to the air inlet.
CAUTION
Do not
Tightening Threaded Connections
Before each use, check all hoses for wear or damage, and replace as necessary. Be sure all threaded con- nections are tight and free of leaks.
Check fasteners. Tighten or retorque as necessary. Although pump use varies, a general guideline is to retorque fasteners every two months. See Torque Sequence, page 18.
Flushing and Storage
Flush the pump to prevent the fluid from drying or freezing in the pump and damaging it. Always flush the pump and relieve the pressure before storing for any length of time. Use a compatible solvent.
WARNING
To reduce the risk of serious injury whenever you are instructed to relieve pressure, always follow the Pressure Relief Procedure on page 8.
If you are flushing, run the pump long enough to thoroughly clean the pump and hoses, close the air regulator, and remove the suction hose from the solvent and place it in the fluid to be pumped.
If you are shutting down the pump, remove the suction hose from the fluid container, run the pump until the fluid is forced out of the system, and shut off the air supply immediately.
