Binks MACH 1, Mach 1V,
HVLP Spray Gun
MACH 1 With Adjustable Fluid Inlet
The Binks MACH 1 HVLP gun is a
top quality high performance air spray
gun. You only have to pick it up to
feel the difference. Its superbly
balanced forged aluminum body offers
the operator extra comfort and control.
All of the gun’s components are
machined and finished to exacting
tolerances and only the best materials
are used, ensuring years of peak
efficiency.
The MACH 1 HVLP airspray gun has
special nozzles and modifications that
allow it to operate at high transfer
efficiencies in compliance with the
“California South Coast Air Quality
Management District” regulations as
a “high volume, low pressure”
airspray gun.
The air inlet passage in the gun body
incorporates a venturi which limits
airflow. High pressure, low volume
airflow is converted to high volume,
low pressure at this point. Special air
and fluid nozzles enable the gun to
atomize fluid at low air pressures and
velocities, creating the “soft spray”
effect for high transfer efficiencies.
To obtain optimum performance from
your new MACH 1 HVLP airspray
gun, read all instructions carefully.

5/16”
1/4”
Only 34 PSI at gun inlet
25 feet of 1/4” I.D. hose causes
a drop of 26 PSI between the
air supply and the gun.
(NOT RECOMMENDED)
48 PSI at gun inlet
25 feet of 5/16” I.D. hose
causes a drop of 12 PSI
between the air supply
and the gun. For this reason
Binks recommends the use
of 5/16” hose.
(RECOMMENDED)
With 60 psi applied at air supply
CONNECTING GUN TO
“PRESSURE ASSISTED”1 QT. CUP
(Figure 1)
The stainless steel pressure-assisted 1 quart
cup, 80-272, utilizes a low pressure air bleed
port on the gun head to slightly pressurize
the cup and provide fluid flow to the nozzle. A check valve prevents the cup from
depressurizing when the gun trigger is
released and airflow stops.
To connect the gun to the cup, remove
the plug (34) in the gun head and install
the hose barb fitting provided with cup
assembly. Attach cup assembly to 3/8"
NPS fluid inlet connection and firmly
tighten. The siphon tube should be angled
toward the front of the gun, i.e. under the
nozzles, and the pressure hose in the cup
lid positioned to the left of the trigger.
Connect check valve assembly hose from
barb fitting on gun head to check valve
inlet fitting on cup cover. Make sure the
check valve is connected so the air comes
from the gun, through the check valve,
into the cup.
Air pressure for atomization is regulated
at the extractor. The flow of the fluid is
adjusted by the fluid valve control knob
on gun, viscosity of paint and air
pressure.
PRESSURE CUP HOOKUP
(Figure 2)
For fine finishing with limited spraying.
Air pressure for atomization is regulated
at extractor; fluid pressure at cup regulator. Pressure cup is also available less
regulator.
PRESSURE TANK HOOKUP
(Figure 3)
For medium production spraying (single
regulator). Air pressure for atomization is
regulated at extractor, fluid pressure at
tank regulator.
PRESSURE TANK WITH
2 REGULATORS (Figure 4)
The pressure to the tank is regulated by
the first regulator. The pressure for
atomization is regulated by the second
regulator.
PRESSURE CIRCULATING
HOOKUP (Figure 5)
For heavy production spraying. Air pressure atomization regulated at extractor.
Fluid pressure regulated at fluid regulator.
AIR PRESSURE
Atomizing pressure must be set properly to allow for the drop in air pressure between the regulator and the
spray gun.
Binks oil and water extractor is important
.
Achieving a fine spray finish without the use of a good oil and water extractor is virtually
impossible.
A Binks regulator / extractor serves a double purpose. It eliminates blistering and spotting
by keeping air free of oil and water, and it gives precise air pressure control at the gun.
Binks recommends using Model HFRL-508 Oil and Water Extractor / Regulator. See your
local distributor for other models.

OPERATION AND MAINTENANCE FOR MACH 1 HVLP SPRAY GUN
Your new MACH 1 HVLP spray gun is
exceptionally rugged in construction and
is built to stand up under hard, continuous use. However, like any other fine
precision instrument, its most efficient
operation depends on a knowledge of its
construction, operation and maintenance. Properly handled and cared for, it
will produce beautiful, uniform finishing
results long after other spray guns have
worn out.
SET-UP FOR SPRAYING
Connecting Gun To Air Hose
Air should be supplied by a suitable
length of 5/16" diameter air hose fitted
with a 1/4" NPS(f) connection at gun
end. For hose lengths over 50', use 3/8"
diameter hose.
Connecting Gun To Fluid Hose
Fluid should be supplied by a suitable
length of 3/8" diameter fluid hose fitted
with a 3/8" NPS(f) connection at gun
end. 1/4" diameter hose is recommended
for use with low viscosity fluids. (Fluid
hoses of different composition are available for special fluids.)
SPRAY GUN CLEANING
INSTRUCTIONS
In certain states it is now against the law
to spray solvents containing Volatile
Organic Compounds (VOC)’s into the
atmosphere when cleaning a spray gun.
In order to comply with these air quality
laws Binks recommends one of the following two methods to clean your spray
finishing equipment:
1. Spray solvent through the gun into a
c
losed system. An enclosed unit or
spray gun cleaning station condenses
solvent vapors back into liquid form
which prevents escape of VOC’s into
the atmosphere.
2. Place spray gun in a washer type
cleaner. This system must totally
enclose the spray gun, cups, nozzles
and other parts during washing, rinsing and draining cycles. This type of
unit must be able to flush solvent
through the gun without releasing
any VOC vapors into the atmosphere.
Additionally, open containers for storage
or disposal of solvent or solvent-containing cloth or paper used for surface
preparation and clean-up may not be
used. All containers shall be nonabsorbent.
Pointers On Cleaning
When used with 1 quart cup, relieve
pressure in the cup. Then unscrew,
empty and carefully rinse cup out with
thinners. Place clean thinners in the cup
and spray this through the gun until it is
clean. Blow air through gun to dry it.
When Used With Pressure
Container
Shut off air supply to container and
release the pressure on the container.
Hold a piece of cloth wadded in the
hand over the gun nozzle (3) and pull
the trigger. The air will back up through
the fluid nozzle and force the fluid out
of the hose into the container. Empty
container. Put enough thinner into the
container to wash hose and gun thoroughly and spray this through the gun
until it is clean. Then blow out the fluid
hose to dry it and remove all traces of
fluid by attaching it to the air line.
When used with Paint
Circulating System
Shut off fluid supply and remove fluid
hose from gun. Clean as gun used with
siphon cup or pressure container or connect quick release on paint line solvent
line. To ensure a clean air supply to your
spray gun, use Binks oil and water
extractor. See your Binks distributor for
the correct model.
GENERAL MAINTENANCE
To Replace Air Valve and
Spindle Assembly
Remove fluid control knob (23), spring
(18) and needle assembly (20). Unscrew
housing (19) and remove spindle assembly (17) with springs (16 & 18), seal
retainers (15) and o-rings (14).
Lubricate new o-rings with Gunners
Mate. Assemble components using fluid
needle. Place this assembly along with
housing (19) into gun body and screw
into position. Remove fluid needle and
tighten housing.
To Replace Needle Seal and
Gland Adapter in Fluid Inlet
Remove fluid control knob (23) and
spring (18) and pull out needle assembly
(20). Unscrew packing nut (31) and
remove spring (30) and seal backup
(29). Using a no. 8 x 1-1/4 coarse thread
wood screw (Binks part no. 20-6536) or
a small sheet metal screw, remove the
needle seal (28) and gland adapter (27).
Replace gland adapter (27) and needle
seal (28). Re-insert seal backup (29),
spring (30) and screw on packing nut
(31) a couple of turns so it fits loosely
by hand. Reassemble needle assembly
(20), spring (18) and fluid control knob
(23). Finally, tighten packing nut (31)
until it bottoms out on fluid inlet (26).
CAUTION
All parts on a spray gun should be
screwed in hand tight at first; this
will avoid the possibility of cross
threading the parts. If the parts
cannot be turned by hand easily,
make sure you have the correct
parts, unscrew, realign, and try
again. NEVER use undue force in
mating parts.

AIR PRESSURE RECOMMENDATIONS
All guns produced since December 15,
1990 have a 54-3946 fan control as standard equipment. Maximum recommended nozzle atomizing pressure is 10 psi.
The 95P and 905P air nozzles are most
suitable for conventional materials.
Use of very low fluid delivery rates with
these nozzles will produce a narrower
than normal fan pattern.
Use the 97P air nozzle for heavy bodied,
high solids materials and low fluid rates
with conventional materials. High flow
rates with light bodied materials may
result in some minor “smoking” or fluid
build-up on the face of these nozzles.

*NOTE
Regulator pressures are based on
25' of 5/16" diameter hose in
good condition without QuickDisconnects or other restrictive
fittings. Use the air nozzle test
gauge accessory to confirm the
atomizing/regulator pressure
relationship for your actual air
supply set-up.
These recommendations are for
“typical” or “average” fluids, and
are intended to serve as a starting
point. Adjust as necessary for
your specific application.
SPRAY TECHNIQUE
The first requirement for a good resultant finish is the proper handling of the
gun. The gun should be held perpendicular to the surface being covered and
moved parallel with it. The stroke
should be started before the trigger is
pulled and the trigger should be released
before the stroke is ended. This gives
accurate control of the gun and fluid.
The distance between gun and surface
should be 6 to 12 inches depending on
fluid and atomizing pressure. The fluid
deposited should always be even and
wet. Lap each stroke over the preceding
stroke to obtain a uniform finish.
GENERAL SPRAY
INSTRUCTIONS
To reduce overspray and obtain maximum efficiency, always spray with the
lowest possible fluid/air pressure that
produces an acceptable spray pattern.
Excessive atomizing air pressures can
increase overspray, reduce transfer efficiency, and with some materials, result
in poor finish quality from dry spray.
Atomizing air pressures should not
exceed 10 psi. See table on page 6, diagram on page 2 and Regulatory Note on
page 8.
For best results, use 3 to 6 psi fluid
pressure. Higher than 6 psi fluid pressure may be required for heavy-bodied
materials. Low fluid pressures will
produce a narrower than normal spray
pattern. Generally use 30-35 psi air at
gun inlet (see page 6). Unusually heavy,
difficult to atomize fluids may require
up to 50 psi air at gun inlet.
CONTROLLING THE FAN SPRAY
The fan spray is controlled by means of
the side port control assembly (7).
Turning this control clockwise until it is
closed will give a round spray; turning it
counterclockwise will widen the spray
into a fan shape. The fan spray can be
turned anywhere through 360 ° by positioning the air nozzle (2) relative to the
gun. To accomplish this, loosen retaining ring (1), position nozzle (2), then
tighten retaining ring (1).
CONTROLLING THE FLUID
FLOW
When used with a pressure assisted cup,
an increase in air pressure will increase
the rate of flow. When fed from a pressure supply, an increase in the fluid
pressure will increase the rate of flow.
Correct fluid nozzle size should be
selected for correct fluid flow rate. The
fluid control knob (23) may be used to
restrict the fluid nozzle (3) opening and
reduce the fluid flow as necessary.
AIR NOZZLE, FLUID NOZZLE,
NEEDLE ASSEMBLY
1. All nozzles and needles are precision made. They should be handled
with care.
2. Except as described in
“ADJUSTING THE NEEDLE
ASSEMBLY”, do not make any
alterations in the gun. To do so
could cause finishing difficulties.
3. To clean nozzles, soak them in solvent to dissolve any dried material,
then blow them clean with air.
4. Do not probe any of the holes in the
nozzles with metal instruments.
If probing is necessary, use only a
tool that is softer than brass.
ADJUSTING THE NEEDLE
ASSEMBLY (20).

TROUBLESHOOTING
Faulty Spray
A faulty spray pattern is often caused by
improper cleaning resulting in dried
materials around the fluid nozzle tip or
in the air nozzle. Soak these parts in
thinners to soften the dried material and
remove with a brush or cloth.
If either the air nozzle (2) or fluid nozzle (3) are damaged, these parts must be
replaced before perfect spray can be
obtained.
Intermittent Spray
If the spray flutters, it is caused by one
of the following faults:
1. Insufficient fluids available. Check
supply and replenish if necessary.
2. Pressure vent tube from gun body
to pressure assist cup is loose or
leaking.
3. Check valve in pressure vent tube is
stuck or blocked.
4. Pressure assist cup cover not
sufficiently tight or cover gasket
defective.
5. Insufficient fluid pressure from
standard pressure pots.

OPERATING THE MACH 1
HVLP SPRAY GUN
NOTE
To reduce overspray and obtain
maximum efficiency always spray
with the lowest possible atomizing
air pressure.
CAUTION
Overtightening may damage the
threads and make future adjustments difficult.
!
CAUTION
Never use metal instruments to clean
the air or fluid nozzles. These parts
are carefully machined and any damage to them will cause faulty spray.
!
Some regulatory agencies prohibit the operation of HVLP spray guns above 10 psi nozzle atomizing pressure. Users subject to this type of regulation should not exceed 10 psi (50 psi gun inlet pressure). See Air
Pressure Recommendations, page 6 and General Spray Instructions, page 4. It is recommended that the
nozzle test gauge (see below) be used to confirm actual nozzle operating pressure.
It may also be a requirement of some regulatory agencies that users have this gauge nozzle available on
site to verify that the gun is being operated within the limits of applicable rules.
