Preventive Maintenance
Schedule
The operating conditions of your particular system
determine how often maintenance is required. Establish
a preventive maintenance schedule by recording when
and what kind of maintenance is needed, and then
determine a regular schedule for checking your system.
Flushing
Flush the pump:
• Before the first use
• When changing colors or fluids
• Before fluid can dry or settle out in a dormant pump
(check the pot life of catalyzed fluids)
• Before storing the pump.
Flush with a fluid that is compatible with the fluid you are
pumping and with the wetted parts in your system.
Check with your fluid manufacturer or supplier for rec-
ommended flushing fluids and flushing frequency.

2. Remove the spray tip from the gun. See the gun
manual.
3. Remove the filter element from the fluid filter (4).
Reinstall the filter bowl.

3–way recirculation valve (46) to the circulation posi-
tion.

or lower the agitator (102) into a container of sol-
vent. Start the agitator and run it slowly.
6. Hold a metal part of the gun firmly to the side of a
grounded metal pail.

pressure when flushing.

The pump will continue to cycle as long as air is
supplied and the back pressure regulator (12) is
open.
10. Direct the drain hose (43) into a waste container.
Set the 3–way recirculation valve (46) to the drain
position. Continue flushing until clear fluid comes
from the hose.

separately, then reinstall them.
