contact with solvents or paints as they will
irritate skin. After any contact, immediately
wash off exposed area with hot, soapy water.

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

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

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

11. WARNING: Some dust created by power
sanding, sawing, grinding, drilling, and
other construction activities, contains
chemicals known [to the State of California]
to cause cancer, birth defects or other
reproductive harm.
Some examples of these chemicals are:

• Lead from lead-based paints

• Crystalline silica from bricks and cement or

other masonry products

• Arsenic and chromium from

chemically treated lumber
Your risk from these exposures varies,
depending on how often you do this type
of work. To reduce your exposure to these
chemicals: work in a well ventilated area,
and work with approved safety equipment,
such as those dust masks that are specially
designed to filter out microscopic particles.

SAFETY OPERATION MAINTENANCESETUP

Initial Set Up

Read the ENTIRE IMPORTANT SAFETY INFORMATION section
at the beginning of this manual including all text under subheadings therein
before set up or use of this product.

Note: For additional information regarding the parts listed in the following

pages, refer to the Assembly Diagram near the end of this manual.

Before Setup

Clean the Spray Gun IMMEDIATELY after use.

1. This air tool may be shipped with a
protective plug covering the air inlet.
Remove this plug before set up.

Air Supply Setup

TO PREVENT SERIOUS INJURY FROM EXPLOSION:
Use only clean, dry, regulated, compressed air to power this tool.
Do not use oxygen, carbon dioxide, combustible gases, or any other bottled gas
as a power source for this tool.

1. Incorporate a filter, regulator with
pressure gauge, in-line shutoff valve, and
quick coupler for best service, as shown
on Figure A on page 7 and Figure B
on page 8. An in-line shutoff ball

valve is an important safety device
because it controls the air supply
even if the air hose is ruptured.
The shutoff valve should be a ball valve
because it can be closed quickly.

Note: Do not use an automatic oiler system or

add oil to airline. The oil will contaminate the
material being propelled, ruining the final result.

2. Attach an air hose to the
compressor’s air outlet. Connect
the air hose to the air inlet of the tool.
Other components, such as a coupler plug
and quick coupler, will make operation
more efficient, but are not required.

2. Before first use, clean the Spray Gun

using a solvent-based thinner.

If not removed, the material used
for testing and corrosion prevention
will contaminate paint.

WARNING! TO PREVENT SERIOUS
INJURY FROM ACCIDENTAL OPERATION:
Do not install a female quick coupler
on the tool. Such a coupler contains

an air valve that will allow the air tool to
retain pressure and operate accidentally
after the air supply is disconnected.

Note: Air flow, and therefore tool performance,
can be hindered by undersized
air supply components.

3. The air hose must be long enough to reach

the work area with enough extra length

to allow free movement while working.

4. Close the in-line shutoff valve between

the compressor and the tool.

5. Turn on the air compressor according to

the manufacturer’s directions and allow

it to build up pressure until it cycles off.

Page 6 For technical questions, please call 1-800-444-3353. Item 61473

NOTICE

Delayed or inadequate cleaning will permanently clog the Spray Gun.

Clean the Spray Gun IMMEDIATELY after use.

6. Adjust the air compressor’s output
regulator so that the air output is enough
to properly power the tool, but the output
will not exceed the tool’s maximum air
pressure at any time. Adjust the pressure
gradually, while checking the air output
gauge to set the right pressure range.

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

8. If the tool will not be used at this time,
turn off and detach the air supply and
safely discharge any residual air pressure
to prevent accidental operation.

Note: Residual air pressure should not be
present after the tool is disconnected from
the air supply. However, it is a good safety
measure to attempt to discharge the tool in a
safe fashion after disconnecting to ensure that
the tool is disconnected and unpowered.

and durability standards, and warrants to the original purchaser that this product is free from
defects in materials and workmanship for the period of 90 days from the date of purchase.
This warranty does not apply to damage due directly or indirectly, to misuse, abuse, negligence
or accidents, repairs or alterations outside our facilities, criminal activity, improper installation,
normal wear and tear, or to lack of maintenance. We shall in no event be liable for death,
injuries to persons or property, or for incidental, contingent, special or consequential damages
arising from the use of our product. Some states do not allow the exclusion or limitation of
incidental or consequential damages, so the above limitation of exclusion may not apply to you.

To take advantage of this warranty, the product or part must be returned to us with
transportation charges prepaid. Proof of purchase date and an explanation of the complaint
must accompany the merchandise. If our inspection verifies the defect, we will either repair or
replace the product at our election or we may elect to refund the purchase price if we cannot
readily and quickly provide you with a replacement. We will return repaired products at our
expense, but if we determine there is no defect, or that the defect resulted from causes not
within the scope of our warranty, then you must bear the cost of returning the product.

This warranty gives you specific legal rights and you may also
have other rights which vary from state to state.
