WARNING
Maintenance Tips:
1.There are two sides for the ball seat, both are chamfered, for one side worn, change to another side.
2.While changing the V-packings(both the upper and lower ones) for piston rod, please note that the convexity side shall be towards the piston rod,
then using rubber hammer to hit the flat side of the V-packings to fit the piston rod.
3. While fastening the screws for the pump block, please do not fasten one screw to maximum and then fasten the other one, the correct action is to
fasten one screw to 90% depth first and then fasten the other screw to maximum and later fasten the first screw to maximum.
4.There is one washing piece inside the pressure sensor, normally the washer won’t be broken, but it can not be left out.
5. After changing the upper V-packings, the nut shall be fully tightened by using a bench clamp.
6. Before starting up a new airless piston pump, please double check the two screws for the pump block and make sure that they are fully fastened.
Same checking after changing new V-packings.As the V-packings are made of high polymer material,after being stocked or used for some time, they
could somehow expand.
7. It’s critically important to turn on the PRIME VALVE before spraying or after changing the paint bucket, if air happens to enter into the piston pump
system and you forget turn on the PRIME VALVE before spraying, it will do big damage to the machine system itself, as the compression ratio for paint
coatings and for air are different.
8.The positive pole and negative pole for the motor can not be connected reversely via the carbon brush,if connected reversely, then the motor will turn
reversely,if the machine runs this way for some time, the motor be become demagnetized. (*For model X20 only)
9. If the V-packings are broken, then there will be paint coatings leakage, please change V-packings immediately, otherwise, the paint coatings may
enter into the gear box to damage the whole gear box.
10. While turning the pressure knob to adjust pressure,please do not turn the knob too hard,as the electric parts inside the knob could be damaged
due to too hard turning.
11.There is micro switch in every airless pump with mechanical pressure control system, and the fixing screw of the micro switch is set properly
before shipment, please do not try to change the position of the fixing screw, otherwise, the micro switch may not work properly.(For X20 model only)
12. One quick tip to identify if the ball seat is good or not, after turning the PRIME VALVE back to spraying position, please open the front cover, if the
connection rod stays on the upper position, then the ball inside the piston rod is somehow damaged, if the connection rod stays on the lower position,
then the ball seat is somehow damaged.
13. If the airless piston pump is not fully cleaned after spraying, the drywall coatings may stop the pressure sensor from working properly, so the airless
piston pump shall be fully cleaned after spraying.
14. If the fuse is burned due to over voltage, please check the capacitor first to see if it’s in good condition, if yes, then please further check the bridge
rectifier with a universal meter.
15.One quick tip to check the pressure control board for airless piston pumps with mechanical pressure control system, first step is to turn on the
PRIME VALVE, then stick to the micro switch with a screw driver, if the machine could stop, means no problem for the pressure control board.
16.If the airless pump is equipped with manifold filter, then the filter shall be often cleaned after spraying,once per day is recommended, or at least
once per week, if the filter is totally stuck by drywall coatings, then the electric board and pressure sensor could be burned, under this situation, fuse
could not protect the electronical board and pressure sensor.
17. As a reminder, for big airless piston pump with big flow rate(mainly refers to X45 and X52/X52L), please do not use short high pressure hose like
3m or 5m, as it might cause serious motor damage. Cleaning the machine, parts every time after finished the paint work.
18.Tips need to replace after 4000 – 5000 m2 depending on abrasiveness of paint.
19.The Piston rod/V-packing and sintered carbide ball need to replace after about 200 hours spraying, Especially when the pressure goes down,
or difficult to draw in paint.
20.For the permanent magnet DC motor, the carbon brush need to replace after 1500 hours, otherwise, the motor will be damaged.
21.Please check every parts had been screwed on the machine very tightly before using machine.
22.If the machine need to be storage over 10 days, Do run the machine with lubricating oil thoroughly, for rust protection or any stuck inside the
pump .(check the details in CLEAN UP)
23.For the maintenance of the fluid pump, do strictly in accordance with the instructions, and screw tightly.(check the details in Service)
24.Please read the manual or contact the distributor if any problems with the machine, DO NOT take the machine to pieces without professional staff.

Trigger Lock
Always engage the trigger lock when you stop spraying
to prevent the gun from being triggered accidentally by
hand or if dropped or bumped.
Pressure Relief Procedure
Follow this Pressure Relief Procedure whenever you
stop spraying and before cleaning, checking, servicing,
or transporting equipment.
1. Turn power switch OFF and unplug
power cord.
2. Turn Prime/Spray valve to PRIME
to relieve pressure.
3. Hold gun firmly to side of pail.
Trigger the gun to relieve
pressure.
4. Engage trigger lock.
NOTE: Leave Prime/Spray valve in the PRIME position
until you are ready to spray again.
If you suspect the spray tip or hose is clogged or that
pressure has not been fully relieved after following the
steps above, VERY SLOWLY loosen tip guard retaining
nut or hose end coupling to relieve pressure gradually,
then loosen completely. Clear hose or tip obstruction.
Read Unclogging Spray Tip instructions in the Sprayer
or Gun Operation manual.

Setup
1. Prepare the paint according to
the manufacturer’s recommendations
This is probably one of the most important steps
toward trouble-free spraying!
Remove any skin that may have formed on the top of
the paint. If necessary, thin the paint. Finally, strain
the paint through a fine nylon mesh filter bag
(available at most paint dealers) to remove particles
that could clog the spray tip
3. Unscrew tip and guard assembly from gun.
4. Uncoil hose and connect one end to gun. Use two
wrenches to tighten securely and tightly.
5. Connect other end of hose sprayer.
6. Oiling
Fill throat packing nut with lubricating oil(3~5 drops) to
prevent premature packing wear, Do this every time
when you spray.
7. Check the electrical service Be sure the electrical
outlet is properly grounded. Longer extension cords
may affect the sprayer performance. Use more spray
hose, not longer extension cords.
8.Plug in the sprayer. First be sure the ON/OFF
switch is OFF and the pressure control is turned fully
counterclockwise. Plug the sprayer into a grounded
outlet that is at least 3 m away from the spray area to
reduce the chance of a spark igniting, spray vapors or
dust particles.
Pressure regulator valve
Clockwise: stronger / Higher pressure
Counter clockwise: weaker / Lower pressure

Startup
1. First be sure the ON/OFF switch is OFF.
2. Adjust Pressure Control counter clockwise to
lowest pressure.
3. Place the suction hose into the coating barrel.
4. Pull up the Prime/Spray Valve to Prime
position.
5. Plug sprayer in a grounded cable socket.
6. Switch ON the machine。
7. Turn the Pressure Control clockwise, till the
fluid is circulating in the prime tube
8. Turn power switch OFF.
9. Transfer suction tube to paint pail and
submerge suction tube in
paint.
10.Turn power switch ON.
11. When you see paint coming out of prime
tube:
(1). Point gun into waste pail.
(2). Unlock gun trigger lock.
(3). Pull and hold gun trigger.
(4). Turn Prime/Spray valve to SPRAY position.
12.Continue to trigger gun into waste pail until
you see only paint coming out of gun.
13. Release trigger. Engage trigger lock.
14.Transfer prime tube to paint pail and clip
prime tube to suction tube.

SPRAYING
SPRAYING TECHNIQUE
1. The key to a good paint job is an even coating over the entire surface. With spray painting, this is
done by using even strokes, with your arm moving at a constant speed and keeping the spray gun a
constant distance from the surface.
2. As much as possible, keep the spray gun at right angles to the surface. This means moving your
entire arm back and forth rather than just flexing your wrist.
30cm
3. Keep the spray gun perpendicular to the surface, otherwise one end of the pattern will be thicker
than the other.
Right way to spray
Approximately
10 to 12 Inches
Right way
Wrong
4. In most cases, the best spraying distance is 10 to 12 inches (25-30cm) between the spray tip and
the surface.
5. The spray gun should be triggered off at the end of each stroke and on again at the beginning of the
next. This avoids paint buildup at the end of the stroke which may result in runs and sags. Triggering
at the end of the stroke also saves paint and results in a better looking job. (See picture below)
Approximate Work
10 to 12 Inches
E ven Steady
Stroke
Start stroke End stroke
6. The correct speed for moving the gun will allow a full, wet coating to be
applied without runs or sags. Lapping each stroke about 40% over the
previous stroke produces uniform paint thickness. Spraying in a uniform
pattern alternately from right to left and then left to right, provides a
professional finish. (See picture on the right)
One way to do this is to point the spray tip at the edge of the last stroke

before triggering the gun on.
7. When taking a short break from painting (up to 1 hr.), lock the spray gun trigger OFF, reduce pressure
to its minimum (zero) setting and set the unit to Prime position . Turn sprayer off and unplug. Refer
to Pressure Relief Procedure.
8. For interior corners, such as on a bookcase or inside a cabinet,
aim the gun toward the center of the corner to spray. By dividing the
spray pattern this way, the edges on both sides are sprayed evenly.
Install Tip & Guard on Spray Gun
1. Engage trigger lock.
2. Verify tip and guard parts are assembled in
order shown.
3. Use tip to align seat Tip must be pushed in
guard all the way into guard
4. Screw tip and guard assembly on
gun. Tighten retaining nut.

Tip Selection
Selecting Tip Hole Size
Tips come in a variety of hole sizes for spraying a range of fluids. Your sprayer includes an 0.017 in
(0.43 mm) tip or maybe 0.019” (0.48mm) for use in most spraying applications. For narrow or smaller
surfaces(cabinet,fence,railings), pattern width of 6 inches is the best choice, it will provide sharper
definition and more control; For large surfaces(Ceilings/walls), a wider spray pattern width of 10 to 12
inches is your best choice to cover large areas more quickly.
Using a good-quality spray tip that is appropriately sized for your painting project is critical to achieving
good spraying results, the spray tip controls the amount of paint applied and the area the spray pattern
will cover. A range of tip sizes classified by both hole size and spray pattern width can be used, based
on 3 factors;
1;Coating/painting 2;Surface being sprayed 3;Sprayer's ability to support the tip hole size.
A key difference is sprayers is the maximum tip they can support. Choose your sprayer based on the
coating types you'll be spraying, and make sure the largest tip(hole size) you plan to use is within the
maximum tip size range the sprayer can support.
It is always best to have a machine with more capacity, Fox example, if you plan to use .017 tip
frequently, your sprayer's capacity should be one tip hole size larger(.019 tip), this allows for tip wear,
which causes the tip hose size to increase.
Choosing the Correct Tip
Consider coating and surface to be sprayed. Make sure you use best tip hole size for that coating and
best fan width for that surface.
Tip Hole Size
Tip hole size controls flow rate - the amount of paint that comes out of the gun.
HINTS:
• Use larger tip hole sizes with thicker coatings and smaller tip hole sizes with thinner coatings.
Fan Width Fan width is the size of the spray pattern, which determines the area covered with each
stroke. Narrower fans deliver a thicker coat, and wider fans deliver a thinner coat.

Understanding Tip Number
The last three digits of tip number contain information about
hole size and fan width on surface when gun is held 12 in.
(30.5 cm) from surface being sprayed.
Last two digits = tip hole size in thousands of an inch

Important things to know about tip wear
It's important to replace a tip when it becomes worn, this ensures you''ll have a precise spray pattern,
maximum productivity and a quality finish. When tip wears, the hole (orifice) size increases and spray
pattern width decreases.
Tip life varies by coating, Extend tip life by spraying at the lowest
pressure that breaks up (atomizes)the coating into a complete
spray pattern.
Recommend tip replacement Latex: After 4000~5000 ㎡

CLEAN UP
As with all spray equipment, your sprayer must be cleaned properly or it will not operate properly.
Clogged are the most common causes of problems. If followed, these guidelines will insure trouble
free performance from your sprayer.
1. Do pressure relief procedure.
Remove siphon tube set from paint and place in
flushing fluid.
Note: Use water for water base paint and mineral spirits
for oil base paint
2. Turn power On, turn
prime/spray valve up to
close drain valve.
3. Increase the pressure to about to 1/2
maximum take the trigger safety OFF, trigger
gun until flushing fluid appears.
3. Move the gun to waste pail, hold gun against
pail, trigger gun to throughly flush system,
release trigger and put trigger safety ON.
4. Turn prime valve down to open drain valve
and allow flushing fluid to circulate for 15
seconds to clean drain tube.
5. Raise siphon tube above flushing fluid and
run sprayer for 15 or 30 seconds to drain fluid.

7. Turn up prime valve up to close drain valve,
Trigger gun into flushing pail to purge fluid from
hose, Turn Power OFF.
8. Turn prime valve down to open drain valve,
Unplug sprayer.
9. Remove filters from gun and sprayer, if
installed. Clean and inspect, install filters.
10. If flushing with water, flush again with
mineral spirits, or pump armor, to leave a
protective coating to prevent freezing or
corrosion.
11.If the machine will be storage for over 10 days,
after you cleaned the machine thoroughly,
please take off the suction tube, hose&gun, and
pour about 10ml WHITE lubricating oil into the
fluid pump, Then switch on the machine and let it
keep running (PRIME POSITION) for 5
seconds(once you can see the oil in the prime
tube), This will prevent the wet parts inside being
stuck, corrosive or rusted.
12. Wipe sprayer, hose and gun with a rag
soaked in water or mineral spirits.
