of the tool or serious injury to persons.
Use only clean, dry, regulated compressed air at the
rated pressure or within the rated pressure range as
marked on the tool. Always verify prior to using the
tool that the air source has been adjusted to
the rated air pressure or within
the rated air-pressure range.

1. Do not direct spray at people or animals.

2. Do not exceed maximum air pressure.

3. Do not spray near open flames, pilot lights,
stoves, heaters, the air compressor, or any
other heat source. Most solvents and coatings
are highly flammable, particularly when
sprayed. Maintain a distance of at least 25 feet
from the air compressor. If possible, locate
the air compressor in a separate room.

4. Read all of the information concerning
coating products and cleaning solvents.

Contact the solvent or coating manufacturer as
needed regarding potential chemical reactions.

5. RISK OF INJECTION - Do not point spray gun at
any person or any part of the body. In case of skin
injection, seek medical attention immediately.

6. Industrial applications must follow
OSHA requirements.

7. Spraying hazardous materials may result in serious
injury or death. Do not spray pesticide, acid,
corrosive material, fertilizer, or toxic chemicals.

8. Paints and solvents may be harmful or fatal if
swallowed or inhaled. Avoid prolonged skin
contact with solvents or paints as they will
irritate skin. After any contact, immediately
wash off exposed area with hot, soapy water.

9. Attach all accessories properly to the tool before
connecting the air supply. A loose accessory
may detach or break during operation.

10. Install an in-line shutoff valve to allow immediate
control over the air supply in an emergency,
even if a hose is ruptured.

11. Air hose fittings may get hot during use.
Allow fittings to cool before disconnecting.

can be hindered by undersized air supply components.

2. Attach an air hose to the compressor’s air outlet.

3. The air hose must be long enough to reach
the work area with enough extra length to
allow free movement while working.

4. Turn on the air compressor according to
the manufacturer’s directions and allow it
to build up pressure until it cycles off.

5. Adjust the air compressor’s regulator
so that the air output is:

a. 60 PSI for 64823

b. 70 PSI for 64824

Adjust the pressure gradually, while checking
the regulator, to set the right pressure.

6. Inspect the air connections for leaks.
Repair any leaks found.

7. If the tool will not be used at this
time, turn off the compressor.
