Binks Cub SL HVLP
TOUCH-UP and COATINGS
SPRAY GUN
Binks Mach 1 Cub SL HVLP Gun is
the finest touch-up and specialty coat-
ings gun available today. The gun has
been ergonomically designed to give
operators superb control and comfort
over a range of uses. You feel the gun’s
excellent balance and heft as soon as
you pick it up. The Mach 1 Cub SL
offers three options for fluid supply:
siphon feed, pressure assist feed, and
pressure feed tank hook-ups, making it
one of the most flexible guns for touch-
up work available. The gun body is
made of the finest forged aluminum and
machined to exacting tolerances.
Overall quality is reflected in the gun’s
lustrous and durable anodized finish.
The Mach 1 Cub SL gun operates at
high efficiencies, transferring 65 percent
or more of the fluid to the substrate.
It fully meets operating pressures and
material transfer requirements of
California’s South Coast Air Quality
Management District regulations as a
high volume, low pressure spray gun.
High pressure, low volume air flow is
converted to high volume, low pressure
flows within the gun body. Special air
and fluid nozzles enable the gun to
atomize fluid at low velocities, creating
a soft spray effect for high transfer
efficiencies.
The Mach 1 Cub SL gun is especially
favored in the automotive touch-up and
detailing industries and is well-suited to
other specialty finishing and small area
applications. Several options in fluid
nozzle sizes make the gun adaptable to
a variety of uses. See the Parts List on
page 2 and Fluid Nozzle Table on page
7 for these options.
This Part Sheet contains an exploded
drawing and detailed parts list to enable
a complete understanding of the gun’s
construction. A basic overview of gun
operation, cleaning, care and mainte-
nance, and troubleshooting of common
problems is also provided.

Your new Binks Mach 1 Cub SL HVLP
gun is exceptionally rugged in con-
struction and is built to stand up under
hard, continuous use. However, like any
other precision instrument. its most
efficient operation depends on a knowl-
edge of its construction, operation and
maintenance. Properly handled and
cared for, it will produce beautiful,
uniform finishes long after other spray
guns are worn out.
The Mach 1 Cub SL gun can be used in
three modes: siphon feed, pressure
assist, or pressure feed tank hook-ups.
In siphon mode, lowered air pressure in
the gun draws fluid from the cup into
the gun. The pressure assist function
works when air flows through the cup’s
check valve assembly, pressurizing the
liquid in the cup and and forcing it up
into the gun. Pressure feed modes for
tanks rely on systems that separately
regulate fluid and air flow. Instructions
for assembling the gun with either the
siphon cup or pressure assist cup are
included here and also with the cup
assemblies. Below are brief descrip-
tions and illustrations of the siphon
feed, the pressure assist, and the
pressure feed tank hook-ups.
SIPHON FEED CUP HOOK-UP
Air pressure for atomization is regulat-
ed at extractor. The amount of fluid is
adjusted by fluid control knob on gun,
viscosity of paint, and air pressure.
PRESSURE ASSIST CUP HOOK-UP
Air pressure for atomization is regulated
at the extractor. The fluid pressure is
from the front of the gun, through check
valve to cup.
PRESSURE FEED TANK
HOOK-UPS
For portable painting operations, use
a double regulator pressure feed tank
hook-up. Air pressure for atomization
and for fluid supply is regulated by two
separate air regulators on tank. The Mach
1 Cub SL comes standard with a 40T
fluid nozzle to be used in siphon feed
operations, see note on page 7 regarding
nozzle options and materials use.
HOW TO SET UP YOUR GUN
FOR SIPHON APPLICATIONS
(See Cup Part Sheet for Parts
Identification)
1. Attach one end of vent tube to
connector on cup lid.
2. Push the other end of vent tube down
through loop on side of cup lip.
3. Insert the threaded fluid inlet into
the swivel nut, taking care to
position the vent tube away from
the gun trigger.
4. Rotate the swivel nut until tight to
attach the cup to the fluid inlet.
HOW TO SET UP YOUR GUN
FOR PRESSURE ASSIST
OPERATIONS
1. Screw the swivel nut onto the
threaded end of the fluid inlet.
2. Remove the 1/4" plug and gasket
from the gun.
3. Replace the plug and gasket with
the connector supplied with the cup
assembly.
4. Slip the longer end of the check
valve assembly over the gun connec-
tor and attach the shorter end to the
connector on the cup lid.
CONNECTING TO AIR HOSE
CONTROLLING FLUID FLOW
Air pressure for atomization is regulat-
ed at the extractor (see illustration pg.
4). The flow of fluid is adjusted by the
fluid control knob on the gun, and by
paint viscosity, air pressure, and nozzle
size. Nozzles with larger apertures give
higher flow rates. You can adjust fluid
flow by turning the fluid control knob.
Turn clockwise to restrict the needle
opening, counterclockwise to enlarge it.

HOW TO SET UP and OPERATE YOUR Binks Cub SL HVLP SPRAY GUN
CAUTION
Over-tightening connector will dam-
age its delicate threading.
!
WARNING
REGARDING AIR PRESSURE SAFETY
Shut off air pressure before connect-
ing or disconnecting air hose or
removing any components from the
gun. Air should be supplied by a suit-
able length of 1/4" diameter air hose
fitted with a 1/4" NPS(f) connector at
the gun end. For hose lengths over
25', use 5/16" diameter hose.
!
WARNING
REGARDING PAINTS, SOLVENTS AND
OTHER COATINGS SAFETY
Do not use open containers for stor-
age or disposal of paint, other coat-
ings, cloth, or paper used in
preparation and application. Many
paints and coatings contain volatile
chemicals that are a cause of pollu-
tion and are a health and fire hazard.
Always wear appropriate clothing,
including gloves, and eye protection,
and a respirator when using the gun.

DEVILBISS CLEAN AIR
SEPARATOR FILTER
Achieving a fine spray finish without
the use of a good oil and water
extractor is almost impossible. A
DeVilbiss regulator/separator serves a
double purpose. It eliminates blistering
and spotting by keeping air free of oil
and water, and it gives precise air
pressure control.
We recommend the DeVilbiss HFRL-
509 regulator/separator for use with the
Mach 1 Cub SL gun.
CONTROLLING FAN SPRAY
Fan spray is controlled by the fan con-
trol knob. Turning this knob clockwise
until it is closed will give a small, cir-
cular spray pattern. Opening it counter-
clockwise widens the pattern to a fan
shape. You can adjust the fan pattern to
any angle by changing the position of
the air nozzle by loosening the retain-
ing ring, rotating the air nozzle to the
desired position, and re-tightening the
retaining ring.
See WARNING Regarding
Solvent Safety, Page 3.
CLEANING YOUR GUN
1. Shut off air supply and relieve
pressure in the gun by triggering it.
2. Remove the siphon or pressure
assist cup, empty it, and rinse it
out with solvent.
3. Turn the gun over and pour sol-
vent into the fluid inlet (30).
4. Trigger the gun to allow solvent
to flow through the gun.
5.Use the gun brush (12) to clean the
fluid inlet and the fluid nozzle
(35).
6. Use the fan brush (11) to clean the
outside of the gun.
7. Repeat any step above until the
gun is clean.
8. Blow air through the gun until dry.
9. OPTION: Disconnect the gun
from the air hose and remove the
air and fluid nozzles if they need
separate cleaning. Remove the
fluid needle (10) and wipe it
clean.
10. OPTION: If the gun has been
used in pressure assist mode,
replace the gasket (32) and plug
(31) or place your finger over the
opening to prevent solvent from
leaking out as you rinse the gun’s
interior.
CLEANING YOUR SIPHON AND
PRESSURE ASSIST CUPS
1. Remove the vent tube or check
valve assembly from the gun and
cup assembly.
2. Unscrew the cup from the gun
and rinse cup in solvent.
3. Using a cloth soaked in solvent,
wipe the vent tube or check valve
assembly to remove paint.
CLEANING GUN USED WITH
PRESSURE CONTAINERS
1. Shut off air supply to container and
release pressure on the container.
2. Hold a piece of cloth wadded in
your hand over the gun nozzle
and pull the trigger. Air will back
up through the fluid nozzle and
force material out of the hose into
the container.
3. Empty container. Add enough
thinner to the container to wash
the hose and gun thoroughly.
4. Spray the solvent through the
gun until it’s clean.
5. Blow out the material hose to dry
it and remove all traces of materi-
al by attaching it to the air line.
CLEANING YOUR GUN
UNDER PRESSURE
It has been customary in the industry
to clean paint guns by spraying sol-
vent through them under air pressure.
This method is less effective than the
steps described above. In addition, it
may violate local air quality regula-
tions. Spraying solvent under pres-
sure atomizes it and may release
Volatile Organic Compounds (VOCs)
into the air.

HOW TO CLEAN and MAINTAIN YOUR Binks Cub SL HVLP SPRAY GUN
Oil and Water
Extractor
CAUTION
Do not allow the cup to remain in
contact with solvent for extended
periods of time. Prolonged exposure
to solvent may damage the cup.
!
CAUTION
Never use anything metal to clean
the air nozzle or fluid nozzle. These
parts are precisely machined, and
any damage to them will cause
faulty spray patterns.
!
CAUTION
Never soak vent tube or check
valve assembly in solvent. Doing
so may cause the Viton o-ring to
swell and not function properly.
!
WARNING
Do not use air pressure when clean-
ing the gun. Doing so atomizes the
solvent, possibly releasing Volatile
Organic Compounds (VOCs) into
the air, which may violate local air
quality regulations and may also
pose a health risk.
!

If you wish to clean the gun using
this method, we recommend one of
the following alternatives:
1. Spray solvent through the gun into
a closed system. An enclosed unit
or spray gun cleaning station con-
denses solvent vapors and captures
them, preventing the escape of
VOCs into the atmosphere.
2. Place the spray gun in a washer
type cleaner. This system must
totally enclose the gun, cup, noz-
zles and other parts during wash-
ing, rinsing and draining cycles.
This type of unit must be able to
flush solvent through the gun
without releasing VOCs vapors.
3. When using a washer to clean cups,
take care not to immerse either
siphon or pressure assist cups in
solvent for long periods of time.
Doing so will weaken the cups.

GENERAL INSTRUCTIONS FOR
AIR SUPPLIED PAINT SPRAYING
To reduce overspray and obtain maxi-
mum efficiency, always spray with
the lowest possible fluid and air pres-
sure that produces an acceptable
spray pattern. Excessive atomizing
air pressure 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 the tables on page 6 and Impor-
tant Regulatory Note on page 8.
For best results with pressure feed
set-ups use 1 to 4 psi fluid pressure.
Higher than 4 psi fluid pressure may
be required for heavy-bodied materi-
als. Low fluid pressure will produce a
narrower than normal spray pattern.
Generally use 30-35 psi air at the gun
inlet (see page 7). Unusually heavy,
difficult to atomize materials may
require up to 50 psi air at the gun
inlet.

SPRAY TECHNIQUE FOR YOUR Binks Cub SL HVLP SPRAY GUN
SPRAY TECHNIQUE
To get a good finish you must handle
the gun properly. Hold the gun per-
pendicular to the surface you are
painting. Make each paint stroke par-
allel to the plane of the surface being
painted. Start the stroke before you
trigger the gun and release the trigger
before you end the stroke. This will
give you accurate control of both gun
and material and prevent excessive
build-up of material at the stroke ends.
The distance between the gun and
surface should be 6"-10" depending
on the material and the atomizing
pressure. The material deposited
should always be even and wet. Lap
each stroke about half of the preced-
ing stroke to obtain a uniform finish.
IF YOU HAVE TROUBLE
WITH GUN OPERATION
OR RESULTING FINISH
FAULTY SPRAY PATTERN
A faulty spray pattern is often caused
by dried materials around the fluid
nozzle tip or in the air nozzle left
behind by improper cleaning. Soak
these parts in thinner to soften the
material and remove it with brush
or cloth.
INTERMITTENT SPRAY
Fluttering spray is caused by one
of the following problems:
1.The nut that attaches the fluid cup
may be loose. The packing nut
(28) may be loose. The packing
(29) may be worn and need
replacement. The fluid nozzle (35)
may be loose.
2. Insufficient fluid available.
Refill the cup.
SPITTING
Spitting is caused by anything that
restricts the movement of the fluid
needle assembly (10). The probable
causes are:
1. The packing nut (28) is too tight.
2. The fluid needle (13) is bent. You
may be able to straighten it.
Otherwise, it must be replaced.
3. Dried material has built up on the
needle or in the fluid nozzle (35).
4. Lumps or impurities in the fluid.
Strain the fluid.

SPRAY TECHNIQUE
CAUTION
Never use anything metal to clean
the air nozzle. These parts are pre-
cisely machined, and any damage
to them will cause faulty spray
patterns.

Regulator pressures are based on 25' of 1/4" hose in good condition without quick disconnects or other
restrictive fittings. Gun inlet pressures are measured at the gun air inlet with the gun triggered. Use
the Air Nozzle Test Gauge Accessory 54-4150 to confirm the atomizing/regulator pressure for your
actual air supply set-up. These recommendations are typical for average fluids, and are intended to
serve as a starting point. Adjust as necessary for your specific application. Regulator pressures for 5/16"
hose are 3 to 5 PSI lower.

IMPORTANT REGULATORY NOTE
Regulations in some areas prohibit the operation of HVLP spray guns above 10 psi nozzle atomizing
pressure. users subject to this regulation should not exceed 50 psi gun inlet pressure (see the air pressure
chart for various fluid materials on page 7). Some agencies require users to have a nozzle test gauge
available on site to verify gun operating pressures. We recommend that you use Nozzle Test Gauge (Part
No. 54-4150) shown below for accurate nozzle operating pressures.
