Initial flushing
CAUTION
This pump is factory tested in oil. To avoid contami-
nating the masking liquid or the surface being
painted, flush the pump before immersing it in the
masking liquid.
1.
Mount the pump in a 5 gallon pail of warm, soapy
water.
2.
Be sure there is no spray tip in the gun. See Fig. 7
if the tip needs to be removed.
3.
Set the trigger safety latch. See Fig. 1.
4.
Be sure the air regulator handle is turned to zero
(fully left as you look at it).
5.
Connect the air line to the pump.
6.
Release the trigger safety latch.
7.
Aim the gun into the flushing pail and squeeze the
gun trigger and hold it open.
8.
Slowly open the air regulator until the pump is
running slowly and smoothly.
9.
Using very low pressure, direct the spray from the
gun back into the flushing container. Circulate the
soapy water in this way for several minutes. Then
release the trigger, set the trigger safety latch, and
disconnect the air line to the pump.
10. Switch the pump to the clean container of water.
Connect the air line, release the trigger safety
latch, and repeat Step 9, above.
11. Raise the pump out of the pail. Trigger the gun to
force the water from the system. DO NOT run the
pump dry for more than 10 seconds to avoid
damaging the pump packings.
