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 an

acceptable spray pattern.

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.

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.

OPERATING THE MACH 1SL

HVLP SPRAY GUN

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.
