The Binks MACH 1SL 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 1SL 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 1SL HVLP airspray
gun, read all instructions carefully.

TYPES OF INSTALLATION
CONNECTING GUN TO
“PRESSURE ASSISTED” 1 QT. CUP
(Figure 1)
Oil & Water
Extractor
FIG 1
The stainless steel pressure-assisted
1-quart cup 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 (18) 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 bard 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-Assisted Cup
Air pressure for atomization is regulated

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 the HFRL-508 oil and water extractor / regulator.

OPERATION AND MAINTENANCE FOR MACH 1SL HVLP SPRAY GUN
Your new MACH 1SL 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
closed 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 (19), spring
(14) and fluid needle (16). Unscrew housing (15) and remove spindle assembly
(13) with springs (12 & 14), seal retainers
(11) and o-rings (10). Lubricate new
o-rings with Binks Gunner’s Mate. In the
absence of Gunner’s Mate, a sparing
amount of petroleum jelly can be used. If
too much petroleum jelly is used, the air
passages will carry it into the finished
product.
Assemble components using fluid needle.
Place this assembly along with housing
(15) into gun body and screw into position. Remove fluid needle and tighten
housing.
To Replace Cartridge Assembly
Remove fluid control knob (19), spring
(14) and remove fluid needle (16). Pull
back trigger (23) and remove seal cartridge assembly (25) from fluid inlet (24).
Remove and discard plastic packing pin
in new seal cartridge assembly. Attach
seal cartridge assembly to fluid inlet.
Assemble fluid needle (16), spring (14)
and fluid control knob (19) to gun.
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
TYPE OF FLUID ATOMIZING FLUID PRESSURE
PSI RANGE- PSI
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.

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.
NOTE
To reduce overspray and obtain maximum
efficiency always spray with the lowest
possible atomizing air pressure.
GENERAL SPRAY INSTRUCTIONS
To reduce overspray and obtain maximum
efficiency, always spray with the lowest
possible fluid/air pressure that produces
NOTE
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.
an acceptable spray pattern.
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 (19) may be used to restrict the (3)
fluid nozzle opening and reduce the fluid
flow as necessary.
AIR NOZZLE, FLUID NOZZLE,
FLUID NEEDLE
1. All nozzles and needles are precision
made. They should be handled with
care.
2. 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.
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.
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. 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 assist cup
is stuck or blocked.
4. Pressure assist cup cover not sufficiently tight or cover gasket defective.
5. Insufficient fluid pressure from standard pressure pots.

IMPORTANT REGULATORY NOTE
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.
