Maintenance
Shutdown and Care of the Pump
Always stop the pump at the bottom of its stroke to
prevent fluid from drying on the rod and damaging the
throat packings.
WARNING
To reduce the risk of serious injury whenever you
are instructed to relieve pressure, always follow the
Pressure Relief Procedure
on page 6.
Check the tightness of the packing retainer screws (7)
weekly. The screws should be tight enough to stop
leakage, but no tighter. Always

Flushing
If you are pumping fluid which dries, hardens, or sets
up, flush the system with a compatible solvent as often
as necessary to prevent build up of dried fluid in the
pump or hoses.

are instructed to relieve pressure, always follow the
Pressure Relief Procedure
on page 6.
To reduce the risk of static sparking or splashing in the
eyes or on the skin,
relieve the pressure
and remove
the spray tip before flushing. Start the pump. Hold a
metal part of the gun/valve firmly to the side of a
grounded metal pail and use the lowest possible fluid
pressure during flushing. When flushing is complete,
relieve the pressure
again.
