WORK AREA 1. Keep your work area clean and well lit. Cluttered benches and dark areas invite accidents. 2. Do not operate pneumatic tools in explosive atmospheres, such as in the presence of flammable liquids, gases, or dust. Pneumatic tools create sparks which may ignite flammables. 3. Keep bystanders, children, and visitors away while operating a pneumatic tool. Distractions can cause you to lose control. Protect others in the work area from debris such as metal filings and sparks.
2. Do not force the tool. Use the correct tool for your application. The correct tool will do the job better and safer at the rate for which it is designed. 3. Do not use the power tool if the Trigger does not turn it on or off. Any tool that cannot be controlled with the Trigger is dangerous and must be replaced. 4. Disconnect the air hose from the tool before making any adjustments, changing accessories, or storing the tool.
3. Use clean, dry, regulated, compressed air at 90 PSI. Do not exceed the recommended 90 PSI. Never use oxygen, carbon dioxide, combustible gases, or any other bottled gas as a power source for this tool. 4.
