 Place a line of lubricant on the piston. To gain access to
the piston, follow the instructions in cleaning the Unit
for Storage in the Maintenance section of this manual.
 Ensure surface to be painted is free of dust, dirt, and
grease.
 Mask or cover any areas not intended to be painted or
stained. Be aware of wind that may cause your paint or
stain to spray into areas not desired. Always use drop
cloths or other cover to protect areas that are not intended
to be painted or stained.
 Fill the backpack tank with no more than 1.5 gallons of
paint or stain.
NOTE: After every refill of the tank, add a line of lubricant
to the piston. See cleaning the Unit for Storage for
instructions on disassembling the sprayer to gain access
to the piston.
 Select the proper spray tip for desired spray pattern. See
Selecting the Proper Spray Tip.
 Install the battery pack in the backpack unit.
 Connect the paint supply tube to both the backpack unit
and the sprayer.
 Prime the backpack unit:
• Place the motor switch in the forward position.
• Aim into a bucket and squeeze the trigger on the
sprayer to release air inside the unit.
• Once paint is running through both the intake tube and
the return tube, the unit is primed.
• Place the motor switch in the off position.
OPERATION
 Connect the DC power cord of the sprayer into the outlet
on the backpack unit.
 Place the motor switch in the forward position.
 Pull the switch trigger to spray paint. Release the switch
trigger to stop paint spray.
 Practice spraying on a piece of scrap material to test your
spray pattern and to prime the pump before beginning. If
you cannot get a good spray pattern with an even amount
of paint or stain throughout, refer to the troubleshooting
section later in this manual.
NOTE: The pump must be primed after every paint
change and at first use after storing. Spray paint at a
scrap surface for at least 20 seconds to prime.
 To create an even coating over the entire surface:
• Move your arm at a steady rate of speed and make
sure to move your entire arm, not just your wrist.
• Keep the sprayer an even distance from the area being
sprayed, which should be between 8 to 10 inches from
the tip of the sprayer to the surface being sprayed.
• Depress the trigger to begin the spray off the mate-
rial you want to paint. Operate the sprayer in straight
horizontal or vertical strokes across the surface being
painted, then release the trigger off the material to end
the stroke.
NOTE: For spray quality consistency when using thin-
ner paints, it may be necessary to keep the trigger
depressed between strokes.
 When finished, disconnect the DC power cord, then
place the motor switch in the reverse position to allow
unused paint to return to the backpack tank. Then remove
the battery pack, return any unused paint or stain to its
original container, and thoroughly clean the sprayer.
cAUTION:
It is important to thoroughly clean the unit after each
use or when changing colors. Allowing paint or stain to
remain in an idle tool for an extended period can cause
its moving pieces and connectors to seize up.
WARNING:
Do not clean with any flammable liquids such as paint
stripper, paint remover, brush cleaner, mineral spirits,
lacquer thinner, turpentine, acetone, gasoline, kerosene,
etc.
