Installation/Operation
Pressure Relief Procedure
WARNING
INJECTION HAZARD
The system pressure must be manually
relieved to prevent the system from
starting or spraying accidentally. Fluid
under high pressure can be injected through the
skin and cause serious injury. To reduce the risk of
an injury from injection, splashing fluid, or moving
parts, follow the Pressure Relief Procedure
whenever you:
are instructed to relieve the pressure,
stop spraying,
check or service any of the system equipment,
or install or clean the spray tips.
1. Lock the gun trigger safety.
2. Shut off the power supply to the pump. Close any
bleed-type master air valves.
WARNING
Be sure your system has a bleed-type master air
valve (pneumatic pumps only) and a pressure drain
valve. These accessories help reduce the risk of
serious bodily injury, including fluid injection,
splashing in the eyes or on the skin, or injury from
moving parts, if you are adjusting or repairing the
pump or gun.
1. The bleed-type master air valve (air-powered
pumps only) relieves air trapped between this
valve and the pump after the air regulator is shut
off. Trapped air can cause the pump to cycle
unexpectedly.
2. The pressure drain valve assists in relieving fluid
pressure in the displacement pump, hose and gun:
triggering the gun to relieve pressure may not be
sufficient.
3. Unlock the gun trigger safety.
3. Strain the fluid you are spraying if it contains
particles which could clog the spray tip.
4. Hold a metal part of the gun firmly to the side of a
grounded metal pail, and trigger the gun to relieve
pressure.
How to Use the Gun Trigger Safety
5. Lock the gun trigger safety.
1. To lock the gun trigger safety, turn the latch to a
right angle with the gun body. See Fig. 1.
6. Open the drain valve (required in your system),
having a container ready to catch the drainage.
7. Leave the drain valve open until you are ready to
spray again.
If you suspect that the spray tip or hose is completely
clogged, or that pressure has not been fully relieved
after following the steps above, very slowly loosen the
tip guard retaining nut or hose end coupling and relieve
pressure gradually, then loosen completely. Now clear
the tip or hose.
2. To unlock the gun trigger safety, push the latch out
and turn it parallel with the gun body.
The trigger safety is shown
in the locked position.
The trigger safety is shown
in the unlocked position.
System Requirements
WARNING
Keep the wallet-sized warning card provided with
this gun with the operator at all times. The card
contains important treatment information should an
injection injury occur. Additional cards are available
at no charge from Graco Inc.

Installation/Operation
How to Use the Gun
1. Connect a grounded fluid hose to the gun inlet.
See Fig. 2.
2. With no tip installed, start the pump. Flush the
pump according to the instructions supplied with it.
Prime the system with the fluid.
To reduce the risk of serious injury whenever you
are instructed to relieve pressure, always follow the
Pressure Relief Procedure on page 5.
3. Relieve the pressure. Be sure the gun trigger
safety is locked. See Fig. 1.
4. Models 235–460, 235–461, and 235–462: screw
the tip guard (1) and install the tip (A) and the
gasket (2d) in the nut of the tip guard. Screw the
assembly firmly onto the gun. Tighten the assembly with a wrench. See Fig. 2.
NOTE: If the gasket (2d) is not installed, the gun
will leak.
5. Models 235–463, 235–464, 238–591, 236–531 and
238–966: install the SwitchTip (16) and the tip
guard (17). See manual 308–644 or 307–991,
supplied.
A
8. Use a full-open, full-close triggering action. Hold
the gun about 14 in. (350 mm) from and at right
angles to the work surface. Don’t swing the gun in
an arc. Practice to find the best length and speed
of stroke.
How to Adjust the Spray Pattern
WARNING
1
7. If adjusting the pressure does not give a good
spray pattern, follow the Pressure Relief Procedure on page 5 and then try another tip size.
WARNING
To reduce the risk of serious injury whenever you
are instructed to relieve pressure, always follow the
Pressure Relief Procedure on page 5.
1. Relieve the pressure. Loosen the retaining nut
(B). Turn the tip guard so the groove in the tip is
horizontal (C) for a horizontal pattern and vertical
(A) for a vertical pattern. Tighten the retaining nut.
See Fig. 3.
2. The orifice of the spray tip and the angle of the
spray pattern determines the coverage and the
size of the pattern. When more coverage is
needed, use a larger spray tip rather than
increasing the fluid pressure.
CAUTION
The openings in the tip guard reduce paint buildup on
the tip guard while spraying. Any damage to the
sharp edges of the openings causes paint to collect
at that area. Never hang the gun by the tip guard.

6. Start the pump. Adjust the fluid pressure until the
spray is completely atomized. Use the lowest
pressure necessary to get the desired results.
Higher pressure may not improve the spray pattern
and will cause premature tip wear and pump wear.

How to Clean the Spray Tip
and Clear a Spray Tip Obstruction
WARNING
To reduce the risk of fluid injection or splashing in
the eyes or on the skin, do not hold a hand, body
or rag in front of the spray tip when cleaning or
checking a clogged tip. Point the gun toward the
ground or into a waste container when checking to
see if the spray tip is cleared.
Do not try to “blow back” paint; this is not an air
spray gun.
Do not wipe fluid buildup off the gun or spray tip
until pressure is relieved.
Cleaning During the Day
WARNING
To reduce the risk of serious injury whenever you
are instructed to relieve pressure, always follow the
Pressure Relief Procedure on page 5.
1. Relieve the pressure.
2. Clean the front of the tip frequently during the day
to help reduce buildup. Also clean the tip and tip
guard at the end of each work day. Use a solventsoaked brush to clean the spray tip.
Clearing an Obstruction
If the spray tip clogs while spraying, immediately stop
spraying, then:
Gun 235–460, 235–461, 235–462
– with standard tip guard
1. Lock the gun trigger safety, open the pressure
drain valve.
2. Remove the spray tip and blow out the obstruction
by applying air to the front of the spray tip. Or, let
the spray tip and gun nozzle soak to dissolve the
obstruction. If it won’t dissolve, jar it out by tapping
the back of the spray tip against a flat surface.
CAUTION
Never soak the entire gun in solvent. Prolonged
exposure to solvent can ruin the packings.
Gun 235–463, 235–464, 238–591, 236–531 and
238–966 – with RAC guard or Heavy Duty RAC guard
1. Lock the gun trigger safety. Rotate the RAC guard
handle 180. See Fig. 4.
2. Unlock the gun trigger safety. Trigger the gun into
a pail or onto the ground to remove the clog.
3. Lock the gun trigger safety. Rotate the tip handle
to the spraying position.
4. If the tip is still clogged, lock the gun trigger safety,
shut off the sprayer and disconnect the power
source, and open the pressure drain valve to
relieve pressure. Clean the spray tip as shown in

Installation/Operation
How to Check the Gun Diffuser Operation
2a
WARNING
The Fine–Finish Gun, Model 235–462, uses a
pre–orifice in the seat to develop the type of spray
pattern required for fine finishes. The pre-orifice
does not diffuse the spray from the nozzle into an
irregular pattern, as with the other guns covered in
this manual. Therefore, to reduce the risk of an
injection injury when the tip guard is not installed,
such as during cleaning, take extra precautions to
keep your hands and body away from the nozzle of
the gun.
For all other guns, check the diffuser operation weekly.
The gun diffuser/seat (2a) breaks up spray and reduces the risk of fluid injection when the tip is not
installed. Perform the test below. If it fails, replace the
entire Needle Kit, Part No. 235–474, as instructed on
page 9. Diffuser/seats are not sold separately since
the gun will leak if an old needle is used with a new
diffuser/seat.
WARNING
To reduce the risk of serious injury whenever you
are instructed to relieve pressure, always follow the
Pressure Relief Procedure on page 5.
1. Relieve the pressure.
2. Remove the tip guard and spray tip.
3. Start the sprayer and adjust it to the lowest
pressure.
4. Aim the gun into a grounded metal pail while
holding it firmly to the pail. Trigger the gun. If the
fluid emitted is not diffused into an irregular
stream, replace the entire needle kit immediately.
See Fig. 5.
Fig. 5
How to Flush the Gun
Always flush the pump and the gun before the fluid
being sprayed can dry in it.
NOTE: If it is available, the flushing procedure
provided in your pump or sprayer manual should be
used instead of this procedure.
WARNING
FIRE AND EXPLOSION HAZARD
Static sparking and splashing may cause
fire, explosion and serious injury. To
reduce static sparking and splashing,
always remove the spray tip from the gun, and hold
a metal part of the gun firmly to the side of a
grounded metal pail when flushing.
WARNING
To reduce the risk of serious injury whenever you
are instructed to relieve pressure, always follow the
Pressure Relief Procedure on page 5.
1. Relieve the pressure.
2. Remove the tip guard and spray tip. Soak and
clean the parts.
3. Put the pump intake in a grounded pail of water or
solvent.
4. Start the pump at its lowest pressure.
5. Trigger the gun into the original pail. When solvent
appears, release the trigger.
6. Now trigger the gun into the solvent pail. Circulate
the fluid until the system is thoroughly flushed.
7. Relieve the pressure.
