HVLP Spray Gun

Description

High volume, low pressure (HVLP)

paint spray ers are de signed to de liv er

a fine finish with low overspray. The

sprayer can be used to apply various

acrylics, stains, sealers, lacquers, latexes,

and primers. This unit can be used for

painting cabinets, fur ni ture, ma chin ery,

equip ment, walls and trim work. Spray-

ers of this type are not recommended

for au to mo tive final coat. This por ta ble

unit is an ideal alternative to con ven tion-

al spray guns. The HVLP’s high transfer

efficiency pro vides pro fes sion al re sults

with much less material waste and en vi-

ron men tal con tam i na tion than other

con ven tion al spray paint ing sys tems.

Unpacking

When unpacking the sprayer, inspect

carefully for any damage that may

have occurred during transit. Make

sure any loose fittings, bolts, etc., are

tightened before putting sprayer into

service. Each sprayer has been tested

before shipment.

NOTE: The packing nut may need

additional adjustment due to the

packing material relaxing during

shipment.

The fluid used for testing the sprayer

has been drained, but some of this fluid

will remain in the spray gun. This fluid

should be flushed from the spray gun to

prevent contamination of the coating

material. Use a solvent compatible with

the coating to be sprayed.

General Safety

Danger means a

hazard that will cause

death or serious injury if the warning is ignored.

WARNING

Warning means a

hazard that could cause death or serious

injury if the warning is ignored.

Caution means a

CAUTION

hazard that may cause

minor or moderate injury if the warning is

ignored. It also may mean a hazard that will

only cause damage to property.

Notice means any

NOTICE

additional

information pertaining to the product or its

proper usage.

Read all instructions and safety

precautions before operating the unit.

Risk

WARNING

of fire

or explosion! Solvent and

paint fumes can explode or

ignite, causing severe injury

and property damage.

Paints and solvents containing

HALOGENATED HYDROCARBONS can react

explosively with aluminum. Always check

the product’s label before using these

materials in the unit.

Make sure the room is well-ventilated.

Avoid all ignition sources, such as static

electricity sparks, open flames, hot objects,

sparks from connecting and disconnecting

power cords, and working light switches.

Follow the material and solvent

manufacturers’ safety precautions and

warnings. Do not use liquids with flash

points less than 100 degrees Fahrenheit (38

degrees Celsius).

Do not carry TURBINE while spraying.

Keep the turbine at the maximum distance

from the spraying area.

Static electricity can be produced by

HVLP spraying. Make sure any electrically

conductive object being sprayed is

grounded to prevent static sparking. The

sprayer is grounded through the electric

cord. If an extension cord is necessary, the

cord must be a grounded, 115 volt, three

wire type cord.

Attention: Campbell Hausfeld recommends that servicing other than that shown in the instruction manual should be performed by an

authorized service facility.

The Campbell Hausfeld HVLP Spray Gun is a high-volume, low-pressure paint sprayer designed to deliver a fine finish with minimal overspray. This portable unit serves as an ideal alternative to conventional spray guns, offering high transfer efficiency for professional results with less material waste and reduced environmental contamination.

Function Description:

The HVLP spray gun is capable of applying various coatings, including acrylics, stains, sealers, lacquers, latexes, and primers. It is suitable for painting cabinets, furniture, machinery, equipment, walls, and trim work. However, it is not recommended for automotive final coats. The gun operates by using a turbine to generate warm air, which atomizes the paint and propels it onto the surface. The design allows for precise control over material flow, air flow, and spray pattern, ensuring a smooth and even application.

Important Technical Specifications:

While specific numerical specifications like pressure or flow rates are not provided, the manual highlights several key operational aspects:

Paint Cup Capacity: The spray gun is equipped with a 1-quart cup for holding paint.
Needle/Nozzle Kits: The unit comes with an all-purpose material needle kit (three groove rings) installed. Optional thin material (single groove ring) and thick material (two groove rings) needle kits are available for purchase, allowing versatility across different material viscosities.
Viscosity Measurement: A viscosity stick, located in the storage compartment, is used to ensure the material is adequately thinned for optimal spraying. The ideal thinning results in drips about one second apart.
Power Requirement: The sprayer is grounded through an electric cord. If an extension cord is used, it must be a grounded, 115-volt, three-wire type cord.

Usage Features:

Adjustable Spray Patterns: The air cap can be rotated to achieve three distinct spray patterns:
- Horizontal Pattern: For up and down strokes.
- Vertical Pattern: For right-to-left or left-to-right strokes.
- Round Pattern: For strokes in any direction.
Material Flow Control: A material flow control knob allows users to increase or decrease the amount of material being sprayed.
Air Flow Control: An air flow control knob (clockwise to decrease, counterclockwise to increase) helps fine-tune the pattern and reduce overspray.
Quick-Release Paint Cup: The 1-quart paint cup features a locking lever for quick and secure attachment and removal.
Packing Nut Adjustment: The packing nut, located forward of the trigger assembly, can be adjusted to ensure the needle returns freely to the closed position, preventing clogs and maintaining proper function.
Preparation Guidelines: The manual emphasizes the importance of straining paint, filling the cup 1/2 to 3/4 full, and checking material viscosity before spraying. It also provides a material thinning chart for various coatings like acrylics, stains, lacquers, and latex paints.
Spraying Technique: Users are advised to keep the gun 4-9 inches from the surface, move it in smooth, even strokes, and overlap each stroke by 25-50% for best results. For narrow patterns, the gun can be moved as close as 2 inches from the work surface.
Safety Features: The manual highlights critical safety warnings, including the risk of fire or explosion from solvent and paint fumes, the danger of using halogenated hydrocarbons with aluminum, the need for good ventilation, and the importance of grounding electrically conductive objects to prevent static sparking. A respirator or mask is recommended to prevent inhalation of hazardous vapors.

Maintenance Features:

Cleaning Procedure: Thorough cleaning is essential after each use. This involves:
- Removing the material control knob, spring, and needle (pulling the trigger helps remove the needle).
- Unscrewing and removing the retainer ring, nozzle, and airflow ring using the supplied wrench.
- Soaking parts in a suitable solvent (or soap and water for latex).
- Flushing cleaning solvent through the material tube and nozzle until clear.
- Using the cleaning brush to clean the material tube and nozzle.
- Reinstalling components in reverse order, ensuring the nozzle is installed before the needle to prevent damage.
- Using the turbine hose to blow-dry all parts and passages to prevent contamination and oxidation.
Packing Nut Maintenance: The packing nut may require adjustment or replacement when the needle/nozzle assembly is changed or if the needle does not return freely.
Troubleshooting Charts: Comprehensive troubleshooting charts are provided for common issues such as "No material flow," "Slow material flow," "Material leak," "Spray will not shut off," "Pulsating spray," "Excessive overspray," "Spray not uniform (spitting)," "Poor pattern," "Overheating," "Poor air flow," and "Spray tip clogs." Additionally, a "Troubleshooting Chart - Finish Quality" addresses issues like "Orange Peel," "Runs and sags," "Pin-holing and solvent pops," "Fish eye," "Blistering," "Lumpy, coarse surface," and "Mottled surface finish," offering possible causes and corrective actions for each.
