WARNING
HIGH PRESSURE SPRAY CAN CAUSE SERIOUS INJURY.
FOR PROFESSIONAL USE ONLY.
OBSERVE ALL WARNINGS.
Read and understand all instruction manuals before operating equipment.
INJECTION HAZARD:
Fluids under high pressure from spray or leaks can
penetrate the skin and cause extremely serious injury,
including the need for amputation.
NEVER point the spray gun at anyone or any part of the
body.
NEVER put hand or fingers over the spray tip.
NEVER try to stop or deflect leaks with your hand or
body.
ALWAYS have the tip guard in place when spraying.
SPRAY GUN SAFETY i с .
MEDICAL TREATMENT
If any fluid appears to penetrate your skin, get
EMERGENCY MEDICAL CARE 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
(412)681-6669
When spray gun is not actually spraying, always set the
gun safety latch in the closed or “SAFE” position, mak-
ing the trigger inoperative.
DO NOT REMOVE OR MODIFY any part of the gun.
Check diffuser operation by using the lowest possible
spray pressure with spray tip removed. Trigger gun and
maintain firm metal to metal contact between gun and
metal waste container. Fluid emitted should be diffused
into an irregular stream.
KEEP CLEAR OF MOVING PARTS:
The electric motor has an overheating protection device
which automatically restarts the motor when it cools.
So, before examining or working on a motor which has
stopped, shut off the unit, relieve pressure and pull out
the electrical plug. This will avoid the hazard of the
motor starting unexpectedly.
KEEP CLEAR of moving parts when unit is running; do
SYSTEM PRESSURE
This unit develops 2750 psi (190 bar) fluid pressure at
100 cycles per minute. Always be sure that all com-
ponents have a maximum working pressure rating at
least as high.
NEVER leave a pressurized unit unattended.
DO NOT ABUSE HOSE: /mproper use or handling of
hose could result in hose failure and possible personal
injury or property damage.
Handle and route hose carefully to avoid kinking, abra-
sion, cutting or exposure to temperatures above 180°F
CHECK OPERATION OF ALL GUN SAFETY
DEVICES BEFORE EACH USE.
Always remove the tip from the gun to clean it.
Be very careful when removing the spray tip or hose
from gun. A plugged line contains fluid under pressure.
If tip or line is plugged, open the drain valve, then
loosen tip guard or hose coupling slightly and relieve the
pressure slowly before removing completely.
not put your fingers into any openings in shield.
ALWAYS CHECK to be sure switch is OFF and all lines
are clear of moving parts before plugging in the power
cord.
ALWAYS unplug unit before removing shield for any
reason.
(82°C) or below -40°F (-40°C). Do not use hose to pull
unit. Before each use, check entire hose for cuts, leaks,
abrasion or bulging or cover or damage of movement of
couplings. If any of these conditions exist, replace the
hose immediately. Never use tape or any device to at-
tempt to mend the hose.
Do not use chemicals or agents in the hose which are
not compatible with nylon tube and urethane cover of
the hose.
NEVER ATTEMPT TO RECOUPLE THE HOSE!
Tighten all fluid connections securely before each use.
307-075 1
PREVENT STATIC SPARKING
Always be sure all equipment and objects being sprayed
are properly grounded. The high velocity flow of fluid
creates static electricity. Sparks may cause fire or ex-
plosion.
Use only conductive or grounded air and fluid hoses for
airless applications. Be sure gun is grounded through
hose connections.
Use only conductive or grounded fluid hoses for airless
applications. Be sure that gun is grounded through hose
connections.
Once each week, check electrical resistance of hose
(when using multiple hose assemblies, check overall
resistance). Overall (end to end) resistance of un-
pressurized hose must not exceed 29 megohms (max.)
for any coupled length or combination of hose lengths.
If hose exceeds these limits, replace it immediately.
Never exceed 500 ft (150 m) overall combined hose
length.
USE EXTREME CARE WHEN SERVICING:
Before removing any part for cleaning or servicing,
always disconnect power source and carefully relieve
fluid pressure by triggering spray gun, engaging trigger
This unit has a 3-prong grounding plug to protect you
from electric shock. Be sure to plug the unit into a pro-
perly grounded outlet that will accept the 3-prong plug.
Do not remove the third prong.
The green wire of electric cord is connected to the unit
chassis and motor frame and the other two wires are
connected to the switch motor for grounding continuity.
Plug into an outlet at least 20 ft (6m) from the area
where you are spraying. If you use an extension cord, it
must have 3 wires of at least 12 gauge (2.5 mm?) and
should not be over 100 ft (30.3 m) long.
When flushing equipment, remove spray tip, use the
lowest possible pressure, and maintain firm metal to
metal contact between gun and metal waste container.
This reduces the chance of static sparking.
Follow the coating and solvent manufacturer's safety
precautions and warnings.
safety and any other equipment safety locks, and open-
ing any drain or bleeder valves. Leave drain valve open
during servicing. Remove tip from gun for cleaning.
IMPORTANT
United States Government safety standards have been adopted under the Occupational Safety and Health Act. These
standards — particularly the General Standards, Part 1910, and the Construction Standards, Part 1926 — should be
consulted in connection with your use of airless spray equipment.

WARNING
Pressure Relief Procedure
System pressure must be relieved whenever you
are done spraying and before servicing, cleaning
or removing any parts to avoid possible injury
from high pressure fluid in system.
Always follow this procedure: shut off unit, trig-
ger spray gun, engage trigger safety, and slowly
open drain valve. Leave drain valve open until you
are ready to use unit again.
BEFORE INITIALLY PLUGGING IN power supply cord,
do the following:
CHECK GEARBOX LUBE. Remove fill plug and see that
lube level is up to fill plug. See Fig 1.
CAUTION
Use only Graco Gear Oil No. 208-230. DO NOT
use hypoid grease. The gearbox holds 3 pt
(1.4 liter).
CONNECT GUN. Remove plastic cap plug from filter
and screw 50 ft (15 m) fluid hose into the
1/4 NPSM filter outlet. Then connect whip end hose
between fluid hose and gun's inlet connection. Do not
use thread sealer. Do not install spray tip yet; wait until
after flushing unit.
CAUTION 1
Use at least 50 # (15 т) of hose. Don’t use metal |
braid hose.
LUBRICATE PRESSURE CONTROL PLUNGER. Put
several drops of light machine oil on microswitch
plunger once a week to lubricate and prevent material
buildup. See WIRING DIAGRAM, page 7.
PRESET PRESSURE CONTROL. Turn pressure control
knob to lowest setting. This shuts off electricity to
motor. See Fig 1.
CHECK ELECTRIC SERVICE AND PLUG IN. Electric
service must be 115V, 60 HzAC, 15 amp. Before you
plug in cord, be sure circuit is correct.
WARNING y
Be sure power supply cord is plugged into an elec-
trical outlet at least 20 ft (6 m) from area where
you are spraying.
Be sure ON-OFF switch is in OFF position (push in),
then plug power cord into a properly grounded outlet.
Flush Oil Out Of Paint Pump
Flush out new unit with mineral spirits before pumping
paint. This removes oil used for factory testing and rust
prevention. Follow this procedure:
1. Pour half a gallon (2 liter) of mineral spirits into a bare
metal pail. Put suction tube into pail.
2. Point spray gun (with no Reverse-A-Clean Ill! spray
tip installed yet) into a metal waste container and
with a metal part of gun firmly touching the metal
container, squeeze trigger. Now pull the switch out
to ON position and turn pressure control wheel
toward INCREASE until motor starts. Hold trigger
fully open until clean solvent comes from nozzle,
then release it. Keep gun aimed into pail until all fluid
flow stops. Engage trigger safety. This procedure
avoids splashing and static sparking.
3. Check all paint line fittings for leaks while system is
pressurized. If there are any leaks, relieve pressure
according to Pressure Relief Procedure. Then tighten
fittings, start pump and recheck fittings to be sure all
leaks have stopped.
4. Remove suction tube from solvent pail. Squeeze gun
trigger to let pump force the solvent out of hose
(don't let pump run dry for more than 1/2 minute),
release trigger and engage trigger safety, then push
switch into the OFF position.

5. Pull plug out of electrical outlet, put a can under filter
drain valve and slowly open valve to release pressure.
Unscrew filter bowl from the outlet filter and check
to see that screen is clean. Reassemble bowl, hand
tight only. See Fig 2.
6. If you are going to use latex paint or any other water
base material, flush unit with water to completely
remove mineral spirits.
Fill Wetcup
Pour Graco Throat Seal Liquid (TSL) supplied, into wet-
cup until 1/3 full. See Fig 3. Plug cord into outlet.
Mix Paint, Adjust Pressure and Spray
Prepare paint as instructed by manufacturer. Also see
instruction manual 306-997.
Put paint suction tube into pail of paint. Do not install
spray tip yet. Squeeze gun trigger, turn the unit on, and
let it run until all air is forced out of system. To avoid in-
troducing more air into the fluid line, always add paint
to original pail rather than changing pails.
NOTE: If paint is thick and hard to prime, first
remove strainer from suction tube, then
prime unit with water or compatible solvent.
When primed, turn unit OFF, plug immersed
end of suction tube with one finger and
transfer it into pail of thick paint. This keeps
air out of pump for more positive priming.
Replace strainer.
Unplug unit, relieve pressure acording to Pressure Relief
Procedure on page 3, and install Reverse-A-Clean III
spray housing with tip installed (see instruction manual
307-321) on gun. Adjust spray pressure to the lowest
pressure needed for satisfactory operation and spray a
test area to check spray pattern. Refer to instruction
manual 306-997 for spraying technique. For further in-
formation on tip selection, see instruction manual
307-321.
Relieve pressure according to Pressure Relief Procedure
on page 3 and clean out front of tip frequently during
day's operation with a solvent soaked brush, to keep
material from building up and clogging tip.
Cleaning A Clogged Tip
If spray tip clogs while spraying, release spray
gun trigger and turn Reverse-A-Clean handle 180°.
Disengage safety and trigger gun. Fluid pressure should
force obstruction from spray tip. Release trigger,
engage trigger safety, return handle to original position
and resume spraying.
If fluid pressure fails to clear tip, see Reverse-A-Clean
instruction manual No. 307-321
WARNING
NEVER hold your hand or a rag in front of spray
tip when cleaning.
Always point the gun toward the ground or into a
waste container.
Shutdown and Care Of Your Unit
Check packing nut/wet cup periodically and tighten only
as necessary. Overtightening may cause binding and
excessive packing wear.
Clean outlet filter often, and when storing unit. Flush all
paint out of unit as instructed on page 3, on that last

workday of week. If you are using paint that will dry
overnight, flush daily at shutdown.
NOTE: If pump fails to shut off with solvent in it, in-
take valve may be obstructed. Relieve
pressure according to Pressure Relief Pro-
cedure on page 3, remove and clean as in-
structed on page 6 and reassemble while
parts are wet. Then finish flushing.
For very short shutoff periods, relieve pressure accord-
ing to Pressure Relief Procedure on page 3, and leave
suction tube in paint and clean spray tip. Follow safety
procedure on page 2 when removing the tip.
Always wrap hose around hose brackets when storing
unit, even if only overnight, to help protect hose from
damage. Suction hose and tube can be routed around
rear bracket and tube end slipped under front bracket.
Don’t store unit with water in it. Even for overnight
storage you should fill the unit with mineral spirits. This
prevents rust and greatly extends the life of the unit.
CAUTION
To prevent stalling and possible stripping of gears,
don’t let water freeze in the pump in cold weather.
Before each use, squirt one drop of oil onto the lower
pivot point of the pump. See Fig 3.
Periodically, or if motor overheats, unplug unit, relieve
pressure according to Pressure Relief Procedure,
remove shield and clean all paint and dirt off shield and
motor. Change gearbox lube at least once a year. Gear-
case holds 3 pt (1.4 liter}. Don’t use hypoid grease.
Once a month, lubricate needle bearing in displacement
rod; use a grease gun to apply grease to grease fitting.
See Fig 5.

Before Disassembling
Flush if possible. Relieve pressure according to Pressure
Relief Procedure and unplug unit. Remove the thumb-
nuts and raise the front hood of the shield.
Remove Pump
You must remove the pump for service. Disconnect the A ASUCTION
suction and outlet hoses. Remove the socket head SS JAIHOSE
screws, lockwashers, flat washers and thrust washers SO
from the pivot shaft and crank. Be very careful to hold
the pump as you slide it off the shafts, so you don’t и
damage the needle bearings. See Fig 5. SCREW

INTAKE VALVE
Screw the intake valve housing out of the displacement
cylinder. Remove the ball stop pin, guide and ball. Clean
and inspect. Reassemble, using new parts from the
repair kit. Torque intake valve housing to 50 to 150 ft-lb
(68-205 N-m) See Fig 6.
NOTE: You can test the intake valve by filling it with
solvent and seeing if any leaks past the ball.
It shouldn't leak. The valve must be clean for
this test; any dirt will hold the ball off the
seat and let solvent leak past.
Throat Packings, Displacement Rod and Piston
Screw the packing nut out of the pump throat. Carefully
pull the displacement rod and piston out through the
pump throat. Wrap the rod end with tape to protect the
bearing and clamp securely in a vise. Screw the piston
off the rod using a wrench on the hex of the piston (if
it's too tight, heat it in boiling water to soften the
locking compound). Remove the ball, glands and
packings. Slide the throat packings and glands off the
rod. Clean and inspect. Install repair kit parts. Be sure to
put the “Teflon” and leather packings in the order
shown. See Fig 6. Thoroughly clean and degrease the
piston and rod, use locking compound and torque to
400-425 in-Ib (45-48 N-m). If packing bulge makes it
hard to insert the piston into the cylinder, loosen the
piston one turn, insert into the cylinder and tighten the
nut using a hex socket wrench from the intake end of
the cylinder.
Bearings
Use an arbor press to remove and install bearings in the
displacement rod end or intake valve housing. See
Fig 6. When replacing displacement rod bearing be sure
hole in bearing lines up with lubrication hole at the top
of the rod. See Fig 6. Soak the bronze intake valve bear-
ing in oil before installing. Grease the displacement rod
bearing whenever the pump is removed.
Servicing Pressure Control
Shut off and unplug the unit, slowly open drain valve to
release pressure and engage trigger safety. Loosen the
thumbnuts, raise the front hood and slip the shield
back. Disconnect the hoses and filter from the pressure
control.
Replace Microswitch
Remove the switch housing cover and switch shield.
Replace the switch yearly. Connect the wires as shown.
Install the switch shield and screw the cover on snugly.
See Fig 7.
Service Adjusting Mechanism
Loosen the setscrew, then screw out the plunger guide.
See Fig 7. Remove the o-ring and backup ring. Clean
and inspect the parts. The slightest nick or cut in the
o-ring will lead to leakage. Scratches or burrs on the
fluid sealing parts will lead to early failure of the o-ring.
Replace as necessary. Reassemble carefully.
