Flush Storage Fluid
It is important that you flush storage fluid
from the sprayer before using it.
1. Make certain ON/OFF switch is OFF.
2. Separate Drain Tube (smaller) from
Suction Tube (larger). Place Drain
Tube in a waste pail.
3. Submerge Suction Tube into pail filled
with water if spraying water-based
material, or mineral spirits if spraying
oil-based material.
4. Lift Prime/Spray Valve to PRIME posi-
tion.
5. Plug power supply cord into a properly
grounded electrical outlet.
6. For Project Painter Plus go to step 8. All
other models, press the PushPrime but-
ton twice to loosen Inlet Valve ball.
7. Align setting indicator with the START
setting on the pressure control knob.
8. Turn ON/OFF switch to ON position.
9. When sprayer starts pumping, flushing
fluid will flow up the Suction Tube and
out the Drain Tube. Allow fluid to flow
out of Drain Tube, into waste pail, for 30
to 60 seconds.
10. Turn the ON/OFF switch to OFF posi-
tion.
NOTE: If flushing fluid fails to come out of the
Drain Tube, see Storage/Priming Tool,
page 31.
