Operating Instructions and Assembly Instructions
Airless Painting Systems

Preparation

Airless painting systems, unlike most
other power tools, require additional
care to ensure proper working order.
Following these instructions will
significantly increase the likelihood of
having a positive paint experience. It is
important that the painting
equipment is flush/tested EACH
time a new job is started. Each pump
is tested at the factory with a fluid that
must be flushed from the system prior
to painting. It is also required prior to
each successive use to flush the storage
lubricant from the system. Use the
solvent which will be used to clean the
equipment. Refer to the paint
manufacturer's recommendations for
cleaning fluids.
GUNS AND HOSES MUST BE
ATTACHED BEFORE PROCEEDING WITH
THE FOLLOWING STEPS.
(For clarity, illustrations do not include
hoses.)
DO NOT ATTACH THE SUCTION
ASSEMBLY UNTIL INSTRUCTED TO DO
SO IN STEP 6.
1. Turn pressure control knob fully
COUNTERCLOCKWISE to the LOW
PRESSURE/HYDRAULIC BLEEDING
position.
2. Turn power switch to the ON
position.
3. Turn prime/spray control to the
PRIME position.
4. Push outlet prime button three
times to ensure outlet valve is
moving freely.
5. Remove inlet valve cap and with
your smallest finger, push on inlet
valve stem to ensure it moves freely.
6. Attach suction assembly securely and
place both suction and bypass tubes
in cleaning solvent.
7. Turn pressure control fully
CLOCKWISE to HIGH PRESSURE
position. In a few seconds, cleaning
solvent will begin to move up
through the tube. Allow the fluid to
circulate for one minute to ensure
all air has been exhausted from the
pump.
