Graco 3A0410D Pump Shutdown, Maintenance Schedule, Flushing and Storage, Lubrication

Operation

Pump Shutdown

At the end of the work shift and before you check, adjust, clean or repair the system, follow the Pressure Relief Procedure, page 12.

Maintenance

Maintenance Schedule Flushing and Storage

Establish a preventive maintenance schedule based on the pump’s service history. Scheduled maintenance is especially important to prevent spills or leakage due to diaphragm failure.

Lubrication

The pump is lubricated at the factory. It is designed to require no further lubrication for the life of the packings. There is no need to add an inline lubricator under nor- mal operating conditions.

Tighten Threaded Connections

Before each use, check all hoses for wear or damage and replace as necessary. Check to be sure all threaded connections are tight and leak-free. Check mounting bolts. Check fasteners. Tighten or retorque as neces- sary. Although pump use varies, a general guideline is to retorque fasteners every two months. See Torque Instructions, page 14.

•Flush before fluid can dry in the equipment, at the end of the day, before storing, and before repairing equipment.

•Flush at the lowest pressure possible. Check con- nectors for leaks and tighten as necessary.

•Flush with a fluid that is compatible with the fluid being dispensed and the equipment wetted parts.

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

NOTICE

Flush the pump often enough to prevent the fluid you are pumping from drying or freezing in the pump and damaging it. Use a compatible solvent.
