Page 3: Work Area
WORK AREA Keep your work area clean and well lit. Cluttered benches and dark areas invite accidents. 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. -
Page 4: Specific Safety Rules
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. Do not use the power tool if the Trigger does not turn it on or off. Any tool that cannot be controlled with the Throttle Lever is dangerous and must be re- placed. - Page 5 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. When connecting to the air supply: Prior to each use, if an automatic oiler is not used, add two drops of air tool oil (not included) into the Air Inlet (47) fitting of the Impact Wrench.

To start the Impact Wrench, squeeze the Trigger (43). To stop the Impact Wrench, release pressure on the Trigger. (See Figure A.)
