MAINTENANCE

Shutdown and Care of the Pump

Always follow the

 Pressure Relief Procedure Warning

on page 7 whenever you shut of f the pump. Stop the

pump at the bottom of its stroke to keep fluid from drying

on the exposed displacement rod and damaging the

throat packings.
Every 40 hours of operation, check that the packing nut/

wet–cup (21) is tight. Follow the 

Pressure Relief Proce-

dure Warning

 on page 7 first. Tighten just snug – do not

overtighten or the packings may be damaged.
Always flush the pump before the fluid dries in the pump

and hoses. If the pump is to be stored for any period of

time, and you are pumping water–based fluid, first flush

the pump with water, then with mineral spirits to protect

the pump parts.

Flushing

To reduce the risk of fluid injection injury, static sparking,

or splashing in the eyes or on the skin, follow the 

Pres-

sure Relief Procedure Warning

 on page 7, and 

remove

the spray tip (spray guns only) before flushing . 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.

Lubrication

The accessory air line lubricator (E) provides automatic

air motor lubrication. For daily , manual lubrication,  dis-

connect the air regulator (C), place about 15 drops of light

machine oil in the pump air inlet, reconnect the regulator

and turn on the air supply to blow oil into the motor.

Corrosion Protection

Water, or even moist air, can cause your pump to

corrode. To help prevent corrosion, never leave the

pump filled with water or air. After normal flushing,

flush the pump again with mineral spirits or oil–

based solvent, relieve pressure, and leave the min-

eral spirits in the pump. Be sure to follow all  steps

of the

 Pressure Relief Procedure W arning

 on

page 7.
