Maintenance
Lubrication
The pump is lubricated at the factory. It is designed to
require no further lubrication for the life of the pump.
NOTICE
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 and Storage
To avoid fire and explosion, always ground
equipment and waste container. To avoid injury
from splashing and static buildup, always flush at
the lowest possible pressure.
• Flush the pump often enough to prevent the fluid
you are pumping from curing, drying, or freezing in
the pump and damaging it.
• Flush with a fluid that is compatible with the fluid
you are pumping and with the equipment wetted
parts.
• Flush the pump and follow the
Pressure Relief Procedure, page 13 , before storing
the pump.
Flush procedures vary widely
by system requirements. See
Start and Adjust the Pump, page 13 , for one common
method of flushing. If your system is different, or if
you are unsure how to completely flush your system,
contact your Graco distributor.
Tighten Threaded Connections
1. Before each use, check all hoses for wear or
damage, and replace as necessary.
2. Check to be sure all threaded connections are
tight and leak-free.
Preventive Maintenance Schedule
Establish a preventive maintenance schedule based
on the service history of the pump. Scheduled
maintenance is especially important to prevent spills
or leakage due to diaphragm failure.
