Important Warnings - Impacts

1. Eye protection and hearing protection and safety gloves must always be worn when operating an impact wrench or impact driver.

2. When using heavy impact sockets or sockets on impact wrenches with 3/4” drive anvils or larger, a socket retaining ring and pin should be used to prevent the socket falling off and causing injury.

3. Use only impact sockets and accessories. Only use sockets designated “FOR USE WITH IMPACT WRENCHES”, hand tool damage and replace when necessary.

Air Supply

Tools of this class operate on a wide range of air pressure. It is recommended that air pressure of these tools measures 90 PSI at the tool while running free. Higher pressure and unclean air will shorten the tool’s life because of faster wear and may create a hazardous condition and void the warranty. Water in the air line will cause damage to the tool. Drain the air tank daily. Clean the air inlet filter screen on at least a weekly schedule. The recommended hookup procedure can be viewed in the illustration below. The air inlet, used for connecting air supply, has standard 1/4” NPT American Thread. Line pressure should be increased to compensate for unusually long air hoses (over 25 feet). Minimum hose diameter should be 3/8” I.D. and fittings should have the same inside dimensions.
