SAFETY WARNINGS & CAUTIONS

1. KEEP WORK AREA CLEAN. Cluttered areas invite injuries.

2. KEEP CHILDREN AWAY. All children should be kept away from the work area. Don't let
them handle tool.

3. DO NOT OPERATE THE TOUCH-UP GUN IF UNDER THE INFLUENCE OF ALCOHOL
OR DRUGS. Read warning labels on prescriptions to determine if your judgment or

reexes are impaired while taking drugs. If there is any doubt, do not attempt to operate.

4. DO NOT SPRAY NEAR OPEN FLAMES, PILOT LIGHTS IN STOVES OR HEATERS,
OR ANY OTHER HEAT SOURCE. Most solvents and coatings are highly ammable,
particularly when sprayed. Always make sure there is adequate ventilation. Extinguish
all cigarettes when painting or cleaning. Industrial applications must follow OSHA
requirements.

5. READ ALL INFORMATION CONCERNING COATING PRODUCTS AND CLEANING
SOLVENTS. Chlorinated solvents, e.g. 1-1-1 Trichloroethane and Methylene Chloride
(also known as methyl chloride) can chemically react with aluminum and may explode.
Many paint sprayers contain aluminum. If you are in any doubt what-so-ever, contact
the solvent or coating manufacturer.

6. MATERIALS USED WHEN PAINTING AND CLEANING MAY BE HARMFUL OR FATAL
IF INHALED AND/OR SWALLOWED. Once again, when spraying, always make sure
there is adequate ventilation. Use a mask or respirator when painting.

7. CHECK ALL SEALS BEFORE CONNECTING TO AIR SUPPLY. Make sure lid is fully

attached to cup, retaining ring is screwed past the rst thread, air pressure plug is
tightened fully, and air supply tube is rmly attached. Never release the lid while the cup

is pressurized.

8. USE EYE PROTECTION. Coatings will cause eye irritation. Wear ANSI approved
chemical splash safety goggles. Goggles are available from Harbor Freight Tools.

When cleaning, be especially careful as solvents can be forcibly ejected from uid and

air passages.

11. STAY ALERT. Watch what you are doing. Use common sense. Do not operate any tool
when you are tired.

12. CHECK DAMAGED PARTS. Before using any tool, any part that is damaged should
be carefully checked to determine that it will operate properly and perform its intended
function. Check for alignment of moving parts, breakage of parts, and other conditions
that may affect its operation.

13. REPLACEMENT PARTS AND ACCESSORIES. When servicing, use only identical
replacement parts. Only use accessories intended for use with this Touch-Up Gun.
Approved accessories are available from Harbor Freight Tools.

14. STORE IDLE EQUIPMENT. When not in use, Touch-Up Gun should be cleaned and
stored, fully assembled, in a dry location to reduce rust. For safety, keep out of reach of
children.

15. MAINTAIN TOOLS WITH CARE. Keep tools clean for better and safer performance.
Follow instructions for lubricating, cleaning and changing accessories. Keep handles
dry, clean and free from oil and grease.

16. OUTDOOR EXTENSION CORDS. When air compressor is used outdoors, use only
rounded jacket extensions cords intended for outside use. See manufacturer’s manual
for the AWG required for the compressor’s amperage draw.

17. BE AWARE OF AIR HOSES AND THEIR CONNECTIONS. Don’t trip over hoses. Make
sure all connections are tight. Keep an eye out for any leaks which should be repaired
immediately.

Step 8. Connect the TOUCH-UP GUN’s coupler to the air

compressor’s hose. If leaking is detected, disconnect the air hose and repair before
use.

PATTERN CONTROL

The Touch-Up Gun is capable of spraying in different fan sizes and different shapes. Never
touch the trigger or point the gun at the face or body when adjusting the fan size or jet
shape.

Adjusting Fan Size

Page 5SKU 00086 For technical questions, please call 1-800-444-3353.

The fan size is adjusted by turning the FAN ADJUSTING SCREW (#28) clockwise for a narrow
spray and counterclockwise for a wider spray.

Adjusting Jet Shape

The Jet Shape is adjusted by turning the AIR CAP (#1). It should be perpendicular to the
ground to create a horizontal jet and parallel to the ground to create a vertical jet.

Adjusting Paint Output

The Volume Output is adjusted by turning the VOLUME ADJUSTMENT SCREW (#12)
clockwise to reduce the output and counterclockwise to increase the output.

SPRAYING TECHNIQUES

Your Touch-Up Gun is designed for light touch-up work, stenciling, and small job duties. For
heavy or medium production work, we suggest our H.V.L.P. and professional model spray guns.

For most uses, e.g. painting walls, benches, vehicles, etc., the best results are obtained by
spraying thin, even coats of paint. Let the layers dry in between coats.

As with any manual process, practice leads to perfection. The following are a few general rules
that may be of help in perfecting your process:

Use the lowest pressure setting •
recommended by the paint manufacturer.

Keep the gun perpendicular to the ground.•

Maintain a distance of about 8” from the work •
as shown in Figure 5.

Make smooth, thin and even strokes across the •
work.

Overlap each stroke by about 50%. (See Figure •

6)

Let each coat dry before re-coating.•

When painting with metallic, pearls, etc., always •
cross coat the paint.

CAUTION:Always keep the LID (#32)

tight when connected to the air source.
