HIGH PRESSURE SPRAY CAN CAUSE SERIOUS INJURY.
FOR PROFESSIONAL USE ONLY. OBSERVE ALL WARNINGS.
Read and understand all instruction manuals before operating equipment.
FLUID INJECTION HAZARD
General Safety
This equipment generatesvery high fluid pressure. Spray from
the gun,leaksor
ruptured components can inject fluid
through your skin and into your body and cause earemely
serious bodily injury, including the need for amputation. Also,
fluid injected or splashed into the eyesor on the skin can
cause serious damage.
NEVER point the spray gun at anyone or at any part of the
body. NEVER put hand or fingers over the spray tip. NEVER
try to "blow back" paint; this is NOT an air spray system.
ALWAYS have the tip guard in place on the spray gun when
spraying.
ALWAYSfollow thePressureReliefProcedure,
below,.
before cleaning or removing the spray tip or servicing any
. ..
system equipment.
NEVER try to stop or deflect leaks with vour hand or body.
Be sure equipment safety devicesare
before each use.
operating properly
M e d i c a l A l e r t - A i r l e s s S p r a y Wounds
If any fluid appears to penetrate your skin, get EMERGENCY
MEDICAL CARE AT ONCE. DONOT
TREAT AS A
SIMPLE CUT. Tell the doctor exactly what fluid was injected.
Note to Physician: Injection in the skin is a traumatic injuty. It is important to treat the injury surgically
as soon
as possible. Do not delay treatment to research toxicity.
Toxicity is a concern with some exotic coatings injected
directly into the blood stream. Consultation with a plastic
surgeon or reconstructive hand surgeon may be advisable.
Spray Gun S a f e t y Devices
Be sure all gun safety devices are operating properly before
each use. Do not remove or modify any part of the gun; this
can cause a malfunction and result in serious bodily injury.
Safety Latch
Whenever you stop spraying, even for a moment, always set
the gun safety latch in the closed or "safe" position, making
the gun inoperative. Failureto set the safety latch can result in
accidental triggering of the gun.
Diffuser
The gun diffuser breaks up spray and reduces the risk of injection when the tip is not installed. Check diffuser operation
regularly. Follow thePressureReliefProcedure.
below,
then remove the spray tip. Aim the.gun into a metal pail,
holding the gun'firmly to the pail. Using the lowest possible
pressure, trigger the gun. If thefluid emitted is notdiffused into an irregular stream, replace the diffuser immediately.
Tip Guard
ALWAYS have-the tip guard in place on thespray gun while
spraying. The tip guard alerts you to the fluid injection hazard
and helps reduce,but does not prevent, the risk of accidentally placing your fingers or any part of your body close to the
spray tip.
Trigger Guard
Always have the trigger guard in place on the gun when spraying to reduce the risk of accidentally triggering the gun if it is
dropped or bumped.
S p r a y Tip Safety
Use extreme caution when cleaning or changing spray tips. If
the spray tip clogs while spraying, engagethe gun safety latch
immediately. ALWAYS follow the PressureRelief
Procedure and then remove the spray tip to clean it.
NEVER wipe off build-up around the spray tip until pressure is
fully relieved and the gun safety latch is engaged.
Pressure Relief Procedure
To reduce the risk of serious bodily iniury, including fluidinjection. splashing fluid orsolvent in the eyes oron the skin, M injury
from moving pans'or electric shock, always follow this procedure whenever you shut off t
payer, when checking or servicing any part of the spray system,when installing, cleaning or changing spray tips,and wT? enever you stop spraying. Ill Engage
the gunsafety latch. 121Turn the ON/OFF switch to OFF. (31 Unplug the power supply cord. I41 Disengagethe gun safety latch.
(51 Hold a metal part of the gun firmly to the side of a grounded metal pail, and trigger the gun to relieve pressure.(61Engage the
gun safety latch. 171 Open the pressure relief valve/pressure relief valve, having a container reedy to catch the drainage. (8)
Leave the pressure relief valve/pressure relief valve open until you are ready to spray again.
If you suspect that the spray tip or hose is completely dogged, or thatpressure has not been fully relieved after following the
then loosen
steps above, VERY SLOWLY loosen the tip guard retaining nut or hose endcoupling and relieve pressure gradually,
completely. Now clear the tip or hose.

EQUIPMENT MISUSE HAZARD
FIRE OR EXPLOSION HAZARD
General Safety
Any misuse of the spray equipment or accessories, such as
overoressurizina. modifvine Darts. using
incompatible
chemicals and fiuids, or using worn or damaged pa&, can
cause them to rupture and result in a fluid injection, splashing
in the eyes or on the skin, or other serious bodily injuw, fire,
explosion or property damage.
Static electricity is created by the high velocity flow of fluid
through the pump and hose. If every part of the spray equipment is not properly grounded, sparking may occur, and the
system may become hazardous. Sparking mayalso occur
when plugging in or unplugging a power supply cord. Sparks
can ignite fumes from solvents and the fluid being sprayed,
dust particles and other flammable substances, whether you
are spraying indoors or outdoors, and can cause a fire or explosion and serious bodily injury and property damage.
Always plug the sprayer into an outlet at least 20 feet 16 m l
away from the sprayer and the spray area. Do not plug in or
unplug any power supply cords in the spray areawhen there is
any chance of igniting fumes still in the air.
NEVER alter or modify any part of this equipment; doing so
could cause it to malfunction.
CHECK all spray equipment regularlyandrepair
worn or damaged parts immediately.
or replace
Read and follow thefluid and solvent manufacturer‘s literature
regarding the use of protective clothing and equipment.
System Pressure
This sprayer can develop 2750 psi 1159 berl MAXIMUM
WORKING PRESSURE. Be surethat all sorav equipment and
accemories are rated to withstand the‘maximum working
pressure of this sprayer. DO NOT exceedthe maximum working pressure of any component oraccessory mBd in the
system.
Fluid and Solvent C o m p a t i b i l i t y
BE SURE that all fluids and solvents used are chemicaliycompatible with the wetted parts shown in the Technical Data on
the back cover. Always read the fluid and solvent manufacturer‘s literature before using them in this sprayer.
If you experience any static sparking or even a slight shock
while using this equipment, STOP SPRAYING IMMEDIATELY. Check the entire system for positive grounding. Do
not use the system again until theproblem has been identified
and corrected.
Groundin
To reduce tf!e risk of static sparking, ground the sprayer and
all other spray equipment used or located in the spray area.
CHECK your local electrical code for detailed grounding instructions for your area and type of equipment:BE SURE to
ground a11 of this spray equipment:
1.
Sprayer: plug the power supply cord, or extension cord,
each equipped with an undamaged three-prong plug, into
a properly grounded outlet. Do not use anadapter. All extension cords must have three wires and be rated for 15
amps.
2.
Fluidhoses: use only grounded hoses with a maximum of
500 feet (150 m l combined hose length to ensure grounding continuity. Refer to Hose Grounding Continuity.
3.
Spray gun: obtain grounding through connection to a
properly grounded fluid hose and sprayer.
ALL FLUID HOSES MUST HAVESPRING GUARDS1 The
spring guards help protect the hose from kinks or bends at or
close to the coupling which can result in hose rupture.
4.
Object being sprayed: according to local code.
5.
Fluid supply container: according to local code.
TIGHTEN all fluid connections securely before each use. High
pressure fluid can dislodge a loose coupling or allow high
pressure spray to be emitted from the coupling.
6.
A
llsolvent pails used when flushing, according to l o u l
code. Use only metalpails, which are conductive. Do not
place the pail on a non-conductive surface, such as papor
or cardboard, which interrupts the grounding continuity.
7.
To maintain grounding continuity when
flushing or relievingpressure, always hold a metal part of the gun firmlyto
the side of a grounded metal pail, then trigger the gun.
HOSE SAFETY
High pressure fluid in the hoses can be very dangerous. If the
hose develops a leak, split or rupture due to any kind of wear,
damage or misuse,the high pressure sprayemitted from itcan
cause a fluid injection injury or other serious bodily injury or
property damage.
NEVER use a damaged hose. Before each use, check the entire hose for cuts, leaks, abrasion, bulging cover, or damage or
movement of the hose couplings. If any of these conditions
exist, replace the hose immediately. DO NOT try to recouple
high pressure hose ormend it withtape or any other device. A
repaired hose cannot contain the high pressure fluid.
HANDLE AND ROUTE HOSES CAREFULLY. Do not pull on
hoses to move equipment, Do not use fluids or solvents which
are not compatible with the inner tube and cover of the hose.
DO NOT exposeGracohose to temperatures above lEWF
182°C) or below -40°F (-4O0Cl.
Hose Grounding Continuity
Proper hose grounding continuity is essentialto maintaining a
grounded spray system.Check the electrical resistanceof your
air and fluid hoses a t least once a week. If your hose doesnot
have a tag on it which specifies the maximum electrical
resistance, contact the hose supplier or manufacturer for the
maximum resistance limits. Use a resistance meter in the appropriate range for your hose to check the resistance. If the
resistanceexceeds the recommended limits, replace it immediately. An ungrounded or poorly grounded hose can make
your system hazardous. Also readFIRE OR EXPLOSION

SHUTDOWN AND CARE
1. Checkthepackingnut/wet-cupdaily.
First
follow the Pressure Relief Procedure Warning
on page 10. Be sure the wet-cup is 1/3 full of TSL
at all times to helpprevent fluid buildup on the
piston rod and premature wear of packings. The
packing nut should
be
tight enough to stop
leakage, but no tighter. Overtightening may cause
binding and excessive packing wear. Use a screwdriverand light hammer to adjust the nut. See
Fig 8.
2. Clean thefluidfilteroften
andwhenever the
sprayer is stored. First follow the Pressure Relief
Procedure Warning on page 10. Refer to manual
307-273,supplied, for the cleaning procedure.
3. Flush thesprayer at the and of each work day
and fill it with mineral spirits to help prevent pump
corrosion and freezing. See "Flushing Guidelines"
on page 12.
Fig 8
4. For very short shutoff periods, leave the suction
tube in the paint, follow the Pressure Relief Procedure Warningon pege 10,and clean the spray
tip.
CAUTION
Never leavewater or any paint
in the sprayer overnight to: ( 1 ) prevent pump corrosion; (2)prevent
the fluid from freezing in the pump and pressure
control which can cause loss of pressure, stalling
orserioussprayerdamage.Alwaysusemineral
spirits for the final flush, follow the Pressure
ReliefProcedureWarning
on page 10, and
leave the mineral spirits in the sprayer.
5. Coil the hose and hang
it on the hose rack when

WARNING
The
pressure
control
MUST
be calibrated
whenever a new or used microswitch or pressure
control assembly is removedandreinstalledor
replaced to be
sure
the
control is properly
calibrated.
Failure
to properly
calibrate
the
pressure control cancause thesprayer to overpressurize and resultin component rupture, fire or
explosion. It may also prevent the sprayer from
obtaining the maximum working pressure which
would result in poor sprayer performance.

'
Fig 21
If only the circuit board (23f) needs to be replacedin the
pressure control, remove the screws (25) and the front
cover (41). See Fig 21. Pull the board out carefully, just
farenough to reach the wire terminals.Unsnap the
wires and finish removing the board.
Position the new card at the control so the wire connactors are at the top. Following the color coded diagramin
Fig 21, snap the wires onto the board. Carefully guide
the wires back into the control, making sure they don't
catch on anything, then slide the new board into place.
Check the pressure control calibration. See page
22.

Tools Needed:
NEW 50 ft (15.2 m) 3000 psi (210 bar) airless spray
hose, Part No. 210-541
Needle valve, Part No. 102-715 or 103-067
3/8' open end wrench
Fluid-filled pressure gauge, Part No. 102-814
5 gallon pail and water
Mineral spirits (for flushing after test)
4. Now check to see at what pressurethesprayer
starts to run again after stalling. Plug in the sprayer,
the
turn it on,close the needlevalve,andset
pressureat maximum. Allow thesprayer to run until
it stalls.
5.
1. Follow thePressureRelief Procedure Warning
on page 14. Install the new 50 ft (15.2 m) spray
hose to thesprayer outlet. On the other end of the
hose install the needle valve. Install the fluid-filled
pressure gauge in the topport of the fluidfilter.
2. Open the needlevalveslightly. Turn the pressure
control knob (Dl to the minimum setting. Plug in
the sprayer and turn the switch ON. Increase the
pressure setting just enough to start the sprayer.
Prime the hose, being sure to eliminate all air from
the system.
If the pressure is lower: shut oft and unplug the
sprayer, but do not relieve pressure. Turn the differential wheel (Fl counterclockwise just one notch
and repeat Steps 4 and 5. Check the pressure drop
again, and repeat if necessary.
NOTE:
6.
3. Open the needlevalvea
little more-enough to
allow the pump to run continuously-and turn the
pressure control knob to maximum. Now, very
slowly start to close the needlevalve, but don't
close it all the way. Observe the pressure a t which
thepump stalls, which shouldbeapproximately
2750 psi (190 bar).
NOTE:
Now open the needlevalvevery slowly while observing the pressuregauge.Check
to see if the
pressure dropsto approximately 2300 psi (161 bar)
before starting again.
If you adjust the differential wheel,recheck
the stall pressure lsteps 2 and 3) to be sure
the stall pressure has not changed.
Followthe Pressure Relief Procedure Warning
on page 14, flush the water out with mineral spirits,
relieve pressure again, then remove the test hose,
needle valve and pressure gauge.
Theslower the pressure is brought up, the
easier it is to note the exact stall pressure.
Closing the needle valve quickly causes the
pressure to rise too fast which gives a false
reading.
If the pressure is lower: unplug the sprayer and
relieve pressure. Use a 3/8' open end wrench to
turn the pressure adjustment nut, at the bottom of
the pressure control knob shaft (R), counterclockwise 1/8 turn or less, then repeat steps 2 and 3.
R-
If the pressure is hisher: unplug the sprayer and
relieve pressure. Turn the pressure adjustment nut
dockwise 1/8 turn or le% and repeat steps2 and 3.
Repeat until the proper stall pressure is obtained.
