WARNING
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 s IL,,. ; ,, , ‘ , ,,,i.. I ,.I, :
s,...,,,,.“.I;<.;
General Safety
This equipment generates very high fluid pressure. Spray from
a spray gun, leaks or ruptured components can inject fluid
through your skin and into your body and cause extremely
serious bodily injury, including the need for amputation. Also,
fluid injected or splashed into the eyes can cause serious
damage.
NEVER point the spray gun or dispensing valve at anyone or at
any part of the body. NEVER put hand or fingers over the
spray tip.
On a spray gun, ALWAYS have the tip guard in place when
spraying.
ALWAYS follow the Pressure Relief Procedure, below,
before cleaning or removing a spray tip or servicing any
system equipment.
NEVER try to stop or deflect leaks with your hand or body.
Be sure equipment safety devices are operating properly
before each use.
Medical Treatment
If any fluid appears to enetrate your skin get
EMERGENCY klEDlCAL CARi AT ONCE.
DO NOT TREAT AS A SIMPLE CUT.
Tell the doctor exactly what fluid was injected. For treatment
instructions, have your doctor call the
NATIONAL POISON CENTER NETWORK
(41216816669
Spray Gun and Dispensing Valve Safety Devices
Be sure all spray gun or dispensing valve safety devices are
operating properly before each use. Do not remove or modify
any part of the gun or valve; this can cause a malfunction and
result in serious bodily injury.
Safety Latch
If your spray gun or dispensing valve has a safety latch, always
set it in the closed or “safe” position whenever you stop
spraying, even for a moment, making sure the gun or valve is
inoperative. Failure to set the safety latch can result in ac-
cidental triggering of the gun or valve.
Diffuser (Spray Guns Only)
The spray gun diffuser breaks up spray and reduces the risk of
injection when the tip is not installed. Check diffuser operation
regularly. Follow the Pressure Relief Procedure, 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 the fluid emitted is not diffused in-
to an irregular stream, replace the diffuser immediately.
Tip Guard (Spray Guns Only)
ALWAYS have the tip guard in place on the gun while spray-
ing. The tip guard alerts you to the injection hazard and helps
prevent accidentally placing your fingers or any part of your
body close to the spray tip.
Trigger Guard
If your spray gun or dispensing valve has a trigger guard,
NEVER operate the gun or valve with the trigger guard remov-
ed. The trigger guard reduces the risk of accidentally trigger-
ing the gun or the valve if it is dropped or bumped.
Spray Tip Safety
Use extreme caution when cleaning or changing spray tips. If
the spray tip clogs while spraying, engage the gun safety latch
immediately. ALWAYS follow the Pressure Relief Pro-
cedure, below, 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 injury, including injection or injury from moving parts, always follow this procedure
whenever you shut off the pump, when checking or servicing any part of the spray or dispensing system, when installing, clean-
ing or changing spray tips, and whenever you stop spraying. (1) Engage the gun safety latch if your spray gun or dispensing
valve has one. (2) Shut off the air to the pump. (3) Close the bleed-type master air valve (required in your system). 14) Disengage
the gun or valve safety latch. (5) Hold a metal part of the spray gun or dispensing valve firmly to the side of a grounded metal
pail, and trigger the gun or valve to relieve pressure. (6) Engage the gun or valve safety latch. (7) Open the pump bleeder valve,
having a container ready to catch the drainage. Also open the fluid drain valve, if your system has one. (81 Leave the bleeder
valve and fluid drain valve open until you are ready to spray or dispense again.
If you suspect that the spray tip< nozzle or hose is completely clogged, or that pressure has not been fully relieved after following
the steps above, VERY SLOWLY loosen the tip guard, nozzle, or hose end coupling and relieve pressure gradually, then loosen
completely. Now clear the tip, nozzle or hose.
Gerieral Safety
Any misuse of the spray equipment or accessories, such as
overpressurizing, modifying parts, using incompatible
chemicals and materials, or using worn or damaged parts, can
cause them to rupture and result in injection or other serious
bodily injury, fire, explosion or property damage.
NEVER alter or modify any part of this equipment; doing so
could cause it to malfunction.
CHECK all spray equipment regularly and repair or replace
worn or damaged parts immediately.
System Pressure
The 551 King pump develops 4950 psi (250 bar) MAXIMUM
WORKhVG PRESSURE at 80 psi (6 bar) MAXIMUM INCOM-
ING AIR PRESSURE. NEVER exceed 90 psi (6 bar) air supply
to the pump. Be sure that all spray equipment and accessories
are rated to withstand the maximum working pressure of this
pump. DO NOT exceed the maximum working pressure of any
component or accessory used in the system.
Material Compatibility
BE SURE that all materials and solvents used are chemically
compatible with the wetted parts shown in the Technical Data
on the back cover. Always read the manufacturer’s literature
before using material or solvent in this sprayer.

FIRE OR EXPLOSION HAZARD ,’ i, f ‘9.i : ,, : -._x
Static electricity is created by the high velocity flow of fluid
through the pump and hose. If every part of the spray system
is not properly grounded, sparking may occur, and the system
may become hazardous. Sparking may also occur when plug-
ging in or unplugging a power supply cord. Sparks can ignite
fumes from solvents and the fluid being sprayed, dust par-
ticles and other flammable substances, whether you are spray-
ing indoors or outdoors, and can cause a fire or explosion and
serious bodily injury and property damage.
Grounding
To reduce the risk of static sparking, ground the pump and all
other components used or located in the spray area. CHECK
your local electrical code for detailed grounding instructions
for your area and type of equipment and be sure to ground all
of these components:
1.
2.
3.
4.
5.
6.
7.
Pump: use ground wire and clamp as shown in Fig 1.
Air and fluid hoses: use only grounded hoses with a max-
imum of 500 feet (150 m) combined hose length to en-
sure grounding continuity. Refer to Hose Grounding
Continuity.
Air compressor: follow air compressor manufacturer’s
recommendations.
Spray gun or dispensing valve: obtain grounding through
connection to a properly grounded fluid hose and pump.
Object being sprayed: according to local code.
All solvent pails used when flushing, according to local
code. Use only metal pails, which are conductive. Do not
place the pail on a non-conductive surface, such as paper
or cardboard, which interrupts the grounding continuity.
To maintain grounding continuity when flushing or reliev-
ing pressure, always hold a metal part of the gun or
dispensing valve firmly to the side of a metal pail, then
trigger the gun or dispensing valve.
HOSE SAFETY
High pressure fluid in the hoses can be very dangerous. If the
hose develops a pinhole leak, split or rupture due to any kind
of wear, damage or misuse, the high pressure spray emitted
from it can cause an injection injury or other serious bodily in-
jury or property damage.
ALL FLUID HOSES MUST HAVE SPRING GUARDS! The
spring guards help protect the hose from kinks or bends at or
close to the coupling which can result in hose rupture.
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.
NEVER use a damaged hose. Before each use, check 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 recouple high
pressure hose or mend it with tape 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 materials or solvents
which are not compatible with the inner tube and cover of the
hose. DO NOT expose the hose to temperatures above 180°F
(82°C) or below -40°F (-40°C).
To ground the pump, loosen the grounding lug locknut (A)
and washer (B). Insert one end of a 12 aa il.5 mm21 minimum
ground wire (D) into the slot in lug (E) and tighten locknut
securely. See Fig 1. Connect the other end of the wire to a
true earthen ground. Refer to page 9 to order a ground wire
and clamp. Connect the clamp end of the ground wire to a
true earthen ground.
Flushing Safety
Before flushing, be sure the entire system and flushing pails
are properly grounded. Refer to Grounding, above. Follow
the Pressure Relief Procedure on page 2. Remove the spray
tip from the gun (spray guns only). Always use the lowest
possible fluid pressure, and maintain firm metal to metal con-
tact between the gun or dispensing valve and the pail during
flushing to reduce the risk of injection injury, static sparking
and splashing.
‘, ‘j ‘,
,
Hose Grounding Continuity
Grace airless spray hoses have electrically conductive material
on the surface of the center core of the hose. Other hoses on
the market may have a ground wire extending the length of
the hose. The ground wire can break in use which will destroy
the electrical grounding of the hose.
To be sure of continuity, check electrical resistance at least
once a week. Check overall resistance when using multiple
hose assemblies. If the resistance exceeds 29 megohms,
replace it immediately. Ground wire hose may have different
resistance; check supplier.
MOVING PARTS HAZARD
Moving parts can pinch or amputate your fingers or other
body parts. NEVER operate the pump with the muffler plates
removed to reduce the risk of injuring your fingers on moving
parts in the air motor. KEEP CLEAR of moving parts when
starting or operating the pump. Before checking or servicing
the pump, follow the Pressure Relief Procedure on page 2
to prevent the pump from starting accidentally. ALWAYS
keep hands clear of the intake valve housing while the pump is
operating.
IMPORTANT
United States Government safety standards have been adopted under the Occupational Safety and Health Act. These standards-par-
ticularly the General Standards, Part 1910, and the Construction Standards, Part 1926-should be consulted.

WARNING
Pressure Relief Procedure
To reduce the risk of serious bodily injury, in-
cluding injection, always follow this procedure
when you stop spraying, and before inspecting,
removing, cleaning or repairing any part of the
pump or system.
1. Engage the safety latch if your spray gun or
dispensing valve has one.
2. Shut off the air to the pump.
3. Close the bleed-type master air valve.
4. Disengage the gun or valve safety latch.
5. Hold a metal part of the spray gun or dispens-
ing valve firmly to the side of a grounded metal
pail, and trigger the gun or valve to relieve
pressure.
6. Engage the gun or valve safety latch.
7. Open the pump bleeder valve, having a con-
tainer ready to catch the drainage. Also open
the fluid drain valve, if your system has one.
3. Leave the bleeder valve and fluid drain valve
open until you are ready to spray or dispense
again.
If you suspect that the spray tip, nozzle or hose is
completely clogged, or that pressure has not been
fully relieved after following the steps above,
VERY SLOWLY loosen the tip guard, nozzle, or
hose end coupling and relieve pressure gradually,
then loosen completely. Now clear the tip, nozzle
or hose.
Flush the pump before using it for the first time to
remove the No. 10 oil which is left in after factory
testing to protect the pump from corrosion. Be sure the
solvent used is compatible with the material to be
sprayed and the wetted parts of the pump.
WARNING
Before flushing, read and follow the instructions
in the section Flushing Safety on page 3 to
reduce the risk of injection injury, static sparking
and splashing.
Starting and Adjusting the Pump
Fill the wet-cup (45) with Grace Throat Seal Liquid
(TSL). Open the dispensing valve (K) and slowly open
the air supply valve until the pump starts. Allow the
pump to cycle slowly, at about 40 psi (3 bar) air
pressure, until all the air is pushed out of the lines. Close
the dispensing valve-the pump will stall against the
pressure. If the pump fails to prime properly, open the
bleeder valve (J) slightly. Use the hole to prime the
pump by covering it until the material appears at the
hole, then uncovering it. See Fig 2.
With the pump and lines primed, and with adequate air
pressure and volume supplied, the pump will start and
stop as the dispensing valve is opened and closed.
Use an air regulator to control pump speed and
pressure. See page 9 for recommended air regulator.
Always use the lowest pressure necessary to obtain the
desired results.
WARNING
ALWAYS keep hands clear of the intake valve
housing while the pump is operating to reduce the
risk of injuring or amputating your hand or fingers.
Lubrication and Care
For air motor lubrication, install an air line oiler as ex-
plained in INSTALLATION, page 4.
Keep the wet-cup (45) filled with TSL to prolong the
packing life.
Always flush the pump before the material can dry in
the pump and hoses. At the end of each day, if you are
pumping water based material, first flush with water,
then with mineral spirits to protect the pump parts.
Read the section Flushing Safety on page 3 before
flushing.
Never allow the pump to run dry of the material being
pumped. A dry pump will quickly accelerate to a high
speed, possibly damaging itself. If your pump ac-
celerates quickly, or is running too fast, stop it im-
mediately and check the material supply. If the supply
has been exhausted and air has been pumped into the
lines, refill the supply container and prime the pump and
lines with material, or flush the pump and leave it filled
with a compatible solvent, being sure to eliminate all air
from the system.
