1 . Remove all parts from the boxes and assemble
them as shown in Fig 1 , following any special notes
on the drawing.
2. Prepare the paint according to the manufacturer‘s
recommendations. Remove anyskin that may have
formed on thetop of the paint. If necessary, thin
the paint.
3. Be sure the electrical service is properly rated for
your sprayer andthat the outlet youuse isproperly
grounded. Install an appropriate plug on the power
supply cord, according
to your local electrical code.
Do not use an adapter. All extension cords must
have three wires. Use the chart a t the right for
selecting the appropriate wire gauge for the extension cord.

WARNING
Never remove the third (grounding) pin of the
power supply cord plug.Be sure the outlet is properly grounded. In the event of an electrical short
circuit, grounding reduces the risk of an electric
shock by providing an escape wire for the electric
current.
Inspect the power supply
cord and extensioncord
before eachuse. Be sura they are in good condition and have undamaged three-pin plugs. Replace
immediately if either cord shows signsof wear or
damage.
4. Loosen the locknut on the telescoping extension
and adjust the extension to the desired length.
Firmly tighten the locknut.

NOTE:
If your system is hardto prime, first try to
force feed the suction tube.
Hold the suction
tube in a vertical position and pour paint
into
it. Turn on the system.
If the system doesnot
prime within one minute, shut it off. Heavy
viscosity paint may need to be thinned. Be
sure to follow the paint manufacturer's
recommendations on thinning.
6. When the outlet hose and extension tube ere
fully
primed, the motor will run when there is paint demand, but appears to shut itselfoff when there is no
paint demand.
NOTE: An occasional start and stop of the motor
when the roller valva not
is triggered is normal.
You can see the paint being drawn
into the suction
tube (if the tube is clean).
As soon as you sae paint
flow through the priming tube, close the priming
valve. This usually takes less than
30 seconds.
OPERATION
WARNING
To reduce the riskof electric shock, do not expose
the systemto rain. Always store the system
indoon.
CAUTION

temperature before usingto prevent damaging the
system. Always store the system indoors.
2. Experiment with triggering and rolling the paint
until
you determine just howoften you need to trigger
the roller valveto keep an evenflow of paint to the
roller.
3. To adjust the extension tube length, loosen the
locknut and extend or retract the tube.
If retracting,
some paint in the tube will be pushed out to the
roller. Roll this excess paint onto the wall, or completely retract the
tube, drain the excess paint into a
pail. then adjust the tube length. Tighten the
locknut securely.
4. Whenever you stop painting, turn the ONlOFF
