INTRODUCTION
Your new Binks AUTOMATIC MACH 1PC 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. 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 AUTOMATIC MACH 1 PC HVLP Gun is an automatic style air spray gun with 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.
A specially designed catalyst injector device is integrated
to the HVLP Gun to inject Methyl Ethyl Ketone Peroxide
or other catalyst into the stream of coating material. The
catalyst is injected immediately after the coating exits the
fluid nozzle for even distribution across the pattern.
The air inlet passage in the gun body incorporates a venturi which limits airflow. High pressure airflow is converted to 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 AUTOMATIC MACH 1 PC HVLP
Spray Gun, read all instructions carefully.

SET-UP FOR SPRAYING
CONNECTING GUN TO MATERIAL HOSE
CONNECTING GUN TO AIR HOSE
Gun should be connected by a suitable length of 3/8" diameter
material hose fitted with a connector with a 3/8" NPS(f) nut at
gun end. 1/4" diameter hose is recommended for use with low
viscosity materials. (Fluid hoses of different composition are
available for special fluids.)
Guns should be connected by a suitable length of 5/16" diameter air hose fitted with a connector and a 1/4" NPS(f) nut at gun
end.
OPERATING THE MACH 1PC HVLP AUTOMATIC SPRAY GUN
CONTROLLING THE MATERIAL FLOW
Flows can be varied by increasing or decreasing fluid pressure.
ADJUSTING AIR AND RESIN FLUID TIMING
A 1/16" gap between the air piston assembly (10) and needle
body (16) should be maintained (see figure 1). This will create
needle motion that will allow adequate air flow before the fluid
starts flowing. The gap may be adjusted by partially removing
the material needle valve (14, 15, 16, 17), screwing the needle
(14) either in or out of the needle body (16), and locking it back
into the gun while being sure to check the clearance between
the air valve piston assembly (10) and the needle body (16).

OPERATION AND MAINTENANCE INSTRUCTIONS
FOR THE AUTOMATIC MACH 1PC HVLP SPRAY GUN
CONNECTING GUN TO THE MATERIAL HOSE
NOTE
Before removing any components from the spray gun,
shut off the air and material pressure, and bleed off excess
material.
BINKS OIL AND WATER EXTRACTOR IS
IMPORTANT
Fluid should be supplied by 3/8" fluid hose (71-3662) typical,
with 3/8" NPS (f) connection at the gun end. A 1/4" hose is recommended for use with low viscosity materials. Fluid hoses of
different composition are available for special fluids.
CONNECTING GUN TO THE CATALYST HOSE
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.
An extractor with a minimum 1/2" pipe inlet is recommended
(103-1273 extractor/regulator).
The catalyst should be supplied by 1/8" catalyst hose (1023027) typical, with 316 SS 1/4" NPS (f) connections at both
ends.
SET-UP FOR SPRAYING
CONNECTING GUN TO THE AIR HOSE
Air should be supplied by 5/16" air hose (71-1203) typical, with
1/4" NPS (f) connection at the gun end. Hose lengths in excess
of 50 ft., use 3/8" hose (71-1356) typical.

OPERATING THE AUTOMATIC MACH 1PC HVLP GUN
CONTROLLING THE MATERIAL FLOW
When used with a pressure tank, an increase in air pressure will
increase the rate of flow. The correct fluid nozzle size should be
selected for the correct material flow rate. Do not use the fluid
needle cover (21) to control resin flow.
NOTE
AIR LEAKS
Damaged seal (11) on piston assembly (10).
UNMIXED RESIN
1. Clogged filter. Remove the fluid manifold (46)
and clean debris from the filter screen.
2. Plugged manifold. Use 102-2658 manifold cleaner
to unplug.
Changing the needle valve opening will affect the ratio of
catalyst: resin and gel.
3. Insufficient catalyst pressure. Increase pressure.
NOZZLE TYPES
Spray patterns are designed by nozzle selection and vary somewhat depending on size, angle, nozzle orifice and output.
OVER CATALYZATION
Fluid nozzle (2) is partially clogged and is restricting the
resin flow. Clean.
NOTE
Metal instruments to clean the air or fluid nozzles are not
recommended. These parts are carefully machined and any
damage to them will cause faulty spray patterns. If either
the air nozzle or fluid nozzle are damaged, these parts must
be replaced before perfect spray patterns can be obtained.
TROUBLESHOOTING
Faulty spray is often caused by:
1. Foreign material in the air and/or fluid passages.
Retaining
Ring
Side Injector
Nozzle
Assembly
2. Viscosity too high for spraying. Air supply or
pressure inadequate.
3. Worn or damaged nozzle surfaces.
4. Gellation in gun head air passages.
5. Loose fluid nozzle.
6. Insufficient material available, check supply and
replenish if necessary.
Line-up fluid manifold assembly to
air cap assembly
and tighten retaining ring. Over
tightening of the
fluid manifold or
improper thread
engagement will
result in crossthreading.
Air Cap
CLEANING
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.
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. Containers shall be nonabsorbent.
In order to comply with these new air quality laws Binks recommends one of the following two methods to clean your spray
finishing equipment:
To clean the gun, flush the fluid lines with solvent and blow air
through the air lines to make sure all the air passages are dry.
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 into the atmosphere.
Never completely submerge the gun in solvent as this will
dissolve the O-Rings and lubricating oil and dry out the
seals.
2. Place spray gun in a washer type container. 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.

!
CAUTION
OPTIONAL HARDWARE
LUBRICATION
Monthly: Remove piston assembly (10) and lubricate the air
cylinder chamber and needle valve spring with a coating of
petroleum jelly.
!
CAUTION
Never use lubricants containing silicone since these
lubricants can cause finish defects. Binks Gunners Mate
(54-3871) is recommended.
REMOVAL OF AIR PISTON
To remove the piston, first unscrew the end cap (20), remove
the 2 springs (18 & 19) and pull out the entire material needle
valve (14, 15, 16, 17). Remove the piston by applying a few
pounds of air pressure to the cylinder air inlet. This air pressure
will cause the piston to pop out.
!
CAUTION
When removing the piston, aim back of gun in a safe
direction and do not use excessive air pressure.
TO REPLACE NEEDLE SEAL AND GLAND ADAPTER
IN FLUID INLET
Remove end cap and needle cover (20 & 21), springs (18 & 19)
and assembled material needle valve consisting of (14, 15, 16,
17). Proceed to the front of the gun and remove manifold
assembly (46) and air cap assembly (1). Next, proceed to bottom of gun and remove 2 bolts (30). Compress half cartridge
(33) and remove air manifold assembly (26) from air manifold
tubing (34). Compress half cartridge (71) inside cylinder body
assembly (54) and remove air tubing (34). Unscrew packing nut
(40) and remove spring (39) and seal backup (38). Loosen 2
bolts (41) and remove S-bracket (35) and partially assembled
catalyst valve assembly (43 thru 45) and (51 thru 71). Next,
remove fluid nozzle (2) from head insert (3). Unscrew head
insert (3) from fluid inlet (42) and remove both from gun body
assembly (4). Using a No. 10 x 1 1/4" coarse thread wood
screw (Binks part no. 20-6536) or small sheet metal screw,
remove the needle seal (37) and gland adapter (36). Reassemble
partially assembled catalyst valve assembly (43 thru 45) and (51
thru 71), and S-bracket (35) to fluid inlet (42).
Replace gland adapter (36) and needle seal (37). Re-insert seal
backup (38) and spring (39). Screw on packing nut (40) a couple of turns so it fits loosely by hand. Reassemble fluid inlet
(42) to gun body (4) with head insert (3). Screw on fluid nozzle
(2). Loosely screw on air cap assembly (1). Align hole in air
cap assembly (1) with hole in body weldment (45) as shown in
assembly drawing, and screw on fluid manifold assembly (46).
Tighten air cap assembly (1) and bolts (41). Assemble air manifold tubing (34) to air manifold assembly (26). Attach the other
end of air manifold tubing (34) to cylinder body assembly (54).
Align gasket (23) and air manifold assembly (26) to body
assembly (4), insert 2 bolts (30) and tighten. Reassemble material needle valve (14, 15, 16, 17), 2 springs (18 & 19), end cap
(20) and fluid needle cover (21). After reassembly, tighten packing nut (40) until it bottoms out on fluid inlet (42).
NOTE
Material needle valve (14, 15, 16, 17) must be installed
before tightening packing nut (40).
REMOVAL AND ADJUSTMENT OF CATALYST INJECTOR PISTON ASSEMBLY
Unscrew and remove cylinder end cap assembly (67) and
Spring (66). Remove piston assembly (60) and loosen locknut
(65). Adjust piston (62) to dimension shown below in view “A”
and re-tighten locknut (65). Lubricate o-ring (63) or replace and
