Using Electrical Cords and Electrical Requirements
3A2854G 7
Using Electrical Cords and
Electrical Requirements
Sprayer must be grounded. Grounding reduces the risk
of static and electric shock by providing an escape wire
for electrical current due to static build up or in the event
of a short circuit.
1. This sprayer requires 220-240 VAC, 50/60 Hz 10A
circuit with a grounding receptacle. Never use an
outlet that is not grounded.
2. Do not use sprayer if electrical cord has damaged
ground prong.
3. Do not use an extension cord with damaged ground
plug.
Recommended extension cords:
•15 m (50 ft) 1.0 mm2
•30 m (100 ft) 1.5 mm2
•50 m (164 ft) 2.5 mm2
4. Smaller gauge or longer extension cords may
reduce sprayer performance.
Power Cord
Extension Cord Requirements
NOTE: When using an extension cord, always use a
cord coupler or an extension cord with locking plugs to
ensure that your sprayer maintains power during opera-
tion.
Your extension cord must have an adequate conductor
size to be able to carry the current that your sprayer
draws. A larger conductor number has a greater capac-
ity than a small one. For example, 7.5 mm2conductor
has a greater capacity than 1.5 mm2conductor. An
undersized extension cord will result in a drop in line
voltage and loss of power, overheating, and possible
damage to equipment.
When using more than one extension cord, make sure
each individual cord contains at least the minimum con-
ductor size needed. The table below shows the correct
size to use depending on extension cord length and
conductor size. If you are unsure, it is better to use a
larger conductor size than needed. Remember, a larger
number indicates a larger conductor size.
ti7529b
ti7528a
• Damaged or entangled cords increase the risk of
electric shock.
• Do not abuse the sprayer cord.
• Do NOT use the cord for carrying, pulling, or
unplugging the sprayer.
• Keep the cord away from heat, oil, sharp edges,
and moving parts.
• Do not operate the sprayer with a damaged cord.
Only use an extension cord with an undamaged
3-prong plug for 220-240 Vac.

Common Procedures
3A2854G 9
Reversible Spray Tip
In the event that particles or debris clog the spray tip,
this sprayer is designed with a reversible spray tip that
can be used to quickly and easily clear the particles and
resume spraying as quickly as possible.
• Always point the reversible spray tip
forward when spraying.
• When particles or debris get caught in the spray tip,
it can be reversed to quickly clean the spray tip.
•SeeUnclogging Spray/Tip Guard Assembly
(page 14) for detailed instructions.
Pressure Control Knob
(Not available on all units)
• To reduce overspray, always spray at lowest pres-
sure that results in an acceptable spray pattern.
• Spray test pattern and adjust pressure to get
desired coverage.
• With some materials, if pressure is set too low, no
material may spray out. Turn pressure control knob
up.
• Thin materials sprayed at high pressure settings
may cause the sprayer to enter an operational mode
designed to protect it from overheating. This mode
is noticeable by the sprayer sounding like it is slow-
ing down and will result ina poor spraying pattern.
To exit this mode, turn pressure control knob
down to lowest pressure setting that results in
an acceptable spray pattern.
• If spraying in low pressure range, there may not be
enough pressure to clear the plug. Turn pressure
control knob up to clear the plug.
Flexible Suction Tube
This sprayer comes with a flexible suction tube for
multi-directional spraying without adjustment.
To ensure proper function of flexible suction tube, orient
flexible suction tube screen end forward (away from trig-
ger) as shown below and push firmly into place.
NOTE: If the sprayer is angled or tilted too far, the
flexible suction tube will lose contact with the material
and the sprayer will stop spraying.
Always perform Pressure Relief Procedure before
adjusting spray tip position.

Choosing the Correct Tip
12 3A2854G
Choosing the Correct Tip
Understanding Tip Number
The last three digits of tip number (i.e.: XXX517) con-
tains information about hole size and fan width on sur-
face when gun is held 12 in. (30.5 cm) from surface
being sprayed.
Example: For a 10 - 12 in. (254 - 305 mm) fan width and
a 0.017 in (0.43 mm) hole size, order part number
XWD517.
Selecting Tip Hole Size
• Tips come in a variety of hole sizes for spraying a
range of fluids. The sprayer includes a 0.017 in.
(0.43 mm) tip for use in most spraying applications.
Use the table below to determine the range of rec-
ommended tip hole sizes for each fluid type.
• Consider coating and surface to be sprayed. Make
sure to use the best tip hole size for the coating and
best fan width for that surface.
• Tip hole size controls flow rate - the amount of paint
that comes out of the gun.
HINTS:
• As you spray, the tip wears and enlarges. Starting
with a tip hole size smaller than the maximum will
allow you to spray within the rated flow capacity of
the sprayer.
• Tips wear with use and abrasive paint and need
periodic replacement.
• Do not spray with worn spray tips. Poor spray pat-
tern quality will result.
Choosing Pressure Control Knob Setting
Recommendations of a starting point for determining the best set point for your sprayer and particular coating are
shown in the table below.
NOTE: Spraying with the .011 tip at high pressure settings may cause the motor to overheat. Shut down sprayer until
it cools and then spray at a lower setting.

3A2854G 13
Install Spray Tip/Guard
Assembly (if not installed)
1. Engage trigger lock and put prime/spray valve UP to
release pressure.
2. Install spray tip filter to spray tip/guard assembly.
NOTE: Spray tip filter is reverse-threaded.
Turn left (or counter-clockwise) to install.
Turn right (or clockwise) to remove.
3. Screw spray tip/guard assembly onto sprayer. Tighten
retaining nut until completely engaged with sprayer. Do
not overtighten nut.
Getting Started with Basic
Techniques
Use a piece of scrap cardboard to practice these basic
spraying techniques before you begin spraying the surface.
• Hold sprayer 10 in. (25 cm) from surface and aim
straight at surface. Tilting sprayer to direct spray angle
causes an uneven finish.
• Flex wrist to keep sprayer pointed straight. Fanning
sprayer to direct spray at angle causes uneven
finish.
NOTE: How fast you move the sprayer will affect spray
application. If material is pulsating, you are moving too fast.
If material drips, you are moving too slow. See Trouble-
shooting, page 25.
Triggering Sprayer
Pull trigger after starting stroke. Release trigger before end
of stroke. Sprayer must be moving when trigger is pulled
and released.
This equipment stays pressurized until pressure is
manually relieved. To help prevent serious injury from
pressurized fluid, such as skin injection, splashing fluid
and moving parts, follow the Pressure Relief
Procedure when you stop spraying and before
cleaning, checking, or servicing the equipment.
NOTICE
Make sure spray tip filter is completely screwed into the
spray tip/guard assembly to avoid damage to the filter.
Do not use a damaged spray tip filter or poor sprayer
performance may result.
Do NOT place hands in front of tip.
NOTICE
The spray tip is a permanently attached to the spray
tip/guard assembly. Removal will result in damage.

Unclogging Spray Tip/Guard Assembly
14 3A2854G
Aiming Sprayer
Aim spray tip of sprayer at bottom edge of previous stroke,
overlapping each stroke by half.
Spray Pattern Quality
A good spray pattern is evenly distributed as it hits the sur-
face. Adjust pressure control knob so pressure is just high
enough to spray without “tails”. If tails persist at highest
pressure setting, a smaller spray tip is needed to spray the
material or material may need to be thinned.
Unclogging Spray Tip/Guard
Assembly
1. To unclog spray tip clog, engage trigger lock and put
prime/spray valve UP to release pressure.
2. Reverse spray tip to UNCLOG position. Turn pressure
control knob to maximum pressure setting.
3. Aim sprayer at waste area, disengage trigger lock, and
put prime/spray valve DOWN to spray position. Pull
trigger to clear clog.
4. Engage trigger lock. Put prime/spray valve UP to
release pressure and rotate spray tip back to SPRAY
position.
5. Disengage trigger lock, put prime/spray valve DOWN
to spray position, and resume spraying.
6. If spray tip is still clogged, you may have to repeat
steps 1 - 5 and rotate the spray tip from SPRAY to
UNCLOG several times. Repeat step 1 to release
pressure, remove and clean spray tip filter, or replace
with new spray tip assembly.
NOTE: Spray tip filter assembly is reverse-threaded:
Turn left (or counter-clockwise) to install.
Turn right (or clockwise) to remove.
7. When obstruction is cleared, engage trigger lock and
rotate spray tip back to SPRAY position.
This equipment stays pressurized until pressure is
manually relieved. To help prevent serious injury from
pressurized fluid, such as skin injection, splashing fluid
and moving parts, follow the Pressure Relief
Procedure when you stop spraying and before
cleaning, checking, or servicing the equipment.

Shutdown and Cleaning
3A2854G 15
Shutdown and Cleaning
The motor has a built-in feature to protect itself from
overuse. If the motor stops, the thermal switch has tripped.
Do not return sprayer to store. The motor will
operate normally after cooling for 20-30 minutes.
For best results, do not spray more than one cup of water
through the tip while cleaning. If more flushing
is needed, remove the tip from the sprayer.
Flushing Sprayer
1. Engage trigger lock and pull prime/spray valve UP to
release pressure.
2. Remove material cup and return excess material to
proper container. If used, properly dispose the material
cup liner.
3. Remove flexible suction tube as shown below.
4. Use screwdriver to pry flexible suction tube strainer
from flexible suction tube.
5. Clean flexible suction tube and suction tube strainer
with water (or flushing fluid) and a brush every time
you flush the sprayer. Reconnect flexible suction tube
and suction tube strainer and orient as shown.
6. Clean material cup if not using a liner, and fill with
water or appropriate flushing fluid.
NOTICE
Failure to properly clean sprayer after each use will
result in hardened materials, damage to the sprayer, and
the warranty will no longer be valid.
Use only water-based materials. Do not use materials
which state “FLAMMABLE” on the packaging. For more
information about your material, request MSDS from dis-
tributor or retailer.
Keep spray area well-ventilated. Keep a good supply of
fresh air moving through the area.
NOTICE
Protect the internal parts of this sprayer from water.
Do not submerge the sprayer in cleaning fluid. Openings
in shroud allow cooling of mechanical parts and electron-
ics inside. If water or cleaning fluid gets into these open-
ings, the sprayer could malfunction or become
permanently damaged.

7. Reconnect material cup and shake sprayer to move
clean water around and clean all areas inside of cup.
8. Disconnect trigger lock and trigger sprayer for approxi-
mately 15 seconds. Engage trigger lock.
9. Discard contaminated fluid and refill with appropriate
flushing fluid.
10. Disengage trigger lock, reverse spray tip to UNCLOG
position, and pull trigger for 5 seconds to prime
sprayer.
11. Put prime/spray valve DOWN to spray position. Trigger
sprayer into waste area until no paint appears in water
or flushing fluid.
IMPORTANT! For best results, do not spray more than
one cup of water through the tip while cleaning. If more
flushing is needed, remove the tip from the sprayer.
12. If sprayer is not completely clean, repeat steps 4-9.
13. Engage trigger lock and put prime/spray valve UP to
release pressure.
NOTE: Air vent holes or the air vent valve (as your
model is equipped) allow air to flow into the material
cup while spraying to prevent loss of fluid flow.
14. Remove material cup and discard used fluid. Use a
soft brush to clean the black rubber inlet seal. If vent
holes become clogged, use a paper clip to clear the
holes.
15. Remove spray tip/guard assembly and clean with
water or flushing fluid. A soft brush can be used to
loosen and remove dried material if needed.

To avoid serious injury or damage to equipment, do not
expose the sprayer electronics to flushing solvents. Keep
sprayer at least 10 in. (25 cm) above the rim of the con-
tainer when flushing.
Keep spray area well-ventilated. Keep a good supply of
fresh air moving through the area. When flushing with sol-
vents, always ground the sprayer and waste container.
NOTICE
The spray tip is permanently attached to the guard.
Removing the spray tip from the guard will result in dam-
age to the spray tip/guard assembly. Do not store spray
tip/guard assembly or flexible suction tube in solvent
other than mineral spirits. Damage to parts may occur.
