increases the flow of liquid. Turning the knob
clockwise decreases the flow of liquid. If runs or drips
do occur, have a dry paint brush on hand to smooth
them out.
Warning! Electric shock hazard. When spraying
overhead, never tip the sprayer more than 45 degrees. The
material being sprayed could leak into the motor housing.
Tip: If the atomizer valve is not seated properly, spray
material will leak from behind the spray nozzle. If material
is leaking, turn off and unplug sprayer from power source
immediately.
Follow these steps to correct the problem:
f Unplug the sprayer from the power source. Follow
steps for "How to Use the Quick Clean System" on
page 34.
If problem presists:
f Check that the sprayer is unplugged from the
power source. Remove the spray nozzle by turning
counterclockwise (Fig. N). For the fan nozzle, remember
to push and turn counterclockwise to remove.
f Remove the atomizer and check to see if it needs to
be cleaned or replaced. Also check inside the pump
housing for any debris or obstruction and clean if
necessary (Fig. N1).
f Replace the atomizer valve making sure it seats
properly (Fig N2).
f Thread the spray nozzle back onto the sprayer by
turning clockwise (Fig. N3).
CLEANING
Warning! Be sure to use appropriate protective gear.
f Make sure clean up area is well ventilated and free of
flammable vapors.
f Always spray outdoors when spraying cleaning
solution through sprayer.
f Use drop cloths during pouring, mixing, and viscosity
testing of materials to be sprayed to protect your
floors and anything else in the spraying area that you
wish to remain untouched.
USING THE QUICK CLEAN SySTEM
The quick clean system allows for a variety of useful
functions. First, the system can allow you to spray water or
a suitable cleaning liquid while there is still spray material
in the main canister. This is useful when setting up your
spray pattern with the fan nozzle. You can spray water
instead of wasting spray material to view the spray pattern.
Second, the quick clean system allows you to flush the
pump assembly, the piston, the nozzle and the atomizer
valve. When spraying for long periods of time, spray
material may build up causing a deterioration of the
spray quality. It is good to flush this system with water or
cleaning liquid after every other spray material refill. It is
also important to flush the system when the sprayer will sit
for more than 15 minutes without use. Spray material can
dry on the nozzle and pump assembly and would require a
thorough cleaning. Always oil piston if sitting idle for a long
period of time. See "Reassembly Section".
Third, the quick clean system allows for a faster O clean-
up when your project is complete. One or two flushes
through the quick clean system gives you a head start on
cleaning the nozzle, the atomizer, the pump and piston,
Please follow recommended cleaning steps in this manual
when performing a final clean of the system.
HOW TO USE THE QUICK CLEAN SySTEM
f Unplug the sprayer from the power source.
f Fill the quick clean fill cup, to the 95ml fill line, with
water or the approprate cleaning solution.
f Open the quick clean door, and pour in the cleaning
solution as shown in Fig. O. Do not overfill the reservoir.
f Switch the quick clean lever from paint to clean (Fig.O1).
f Plug in the sprayer.
f Spray into a waste container, cardboard box or test
surface to completely flush the sprayer system.
f Once the spray pattern turns to only the color of the
cleaning solution, begin cleaning.
f You may need to flush more than once.
Notice! Please note, this is not the final cleaning step.
TO BEGIN CLEANING:
f Unplug the sprayer from the power source.
f Unscrew the lid from the side of the canister and pour any
remaining liquid back into the original container (Fig. P).
f Pour a small amount of the appropriate cleaning
solution into the canister (Fig. P1).
f Warm soapy water for water based materials
f Manufacturers recommended cleaning solution for oil
based materials
f Replace the lid on the canister securely and
vigorously shake the sprayer.
f Unscrew the lid from the side of the canister and
properly dispose of cleaning solution.
f Refill the canister with a small amount of new cleaning
solution (Fig. P1). Screw lid securely on canister.
f Plug in the cord and spray the cleaning solution
through the sprayer onto scrap material for 5 seconds
(Fig. P2).
f Unplug the sprayer from the power source.
f Properly dispose of cleaning solution.
f Remove the spray nozzle, by turning counterclockwise,
then remove the atomizer (Fig.P3). Refer to Fig.C and C1.
f Unscrew the canister from the sprayer by turning the
collar as shown in Fig. P4. Remove the pickup tube and
filter and o-ring from the sprayer. Clean the parts with
the cleaning brush in the appropriate cleaning solution.
