d� Use safety equipment.

Wear heavy‑duty work gloves and a NIOSH‑approved respirator

during use� Non‑skid safety shoes and a hard hat must be used for the applicable conditions�

e� Always wear eye protection.

Wear ANSI‑approved

safety goggles�

d� Check for misalignment or binding

of moving parts, breakage of parts, and any other condition that affects the tool’s operation. If damaged,

have the tool serviced before using� Many accidents are caused by poorly maintained tools� There is a risk of bursting if the tool is damaged�

e� Use only accessories that are identified

by the manufacturer for the specific tool model. Use of an accessory not

intended for use with the specific tool model, increases the risk of injury to persons�

SAFETYOPERATIONMAINTENANCE SETUP

Specific Safety Instructions

NOTICE

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�

Do not use chlorinated solvents (e.g. 1-1-1 trichloroethylene and dichloromethane, also known as methylene chloride) to clean spray guns. Many spray guns contain aluminum, which reacts strongly to chlorinated solvents. Contact the solvent or coating

manufacturer as needed regarding potential chemical reactions�

5� Industrial applications must

follow OSHA requirements�

6� Spraying hazardous materials may

result in serious injury or death� Do not spray pesticide, acid, corrosive material, fertilizer, or toxic chemicals�

7� 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�

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 and 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� (California Health & Safety Code § 25249�5, et seq.)

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

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�
