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.
Accessory Hazards
4. Disconnect the assembly power tool for threaded fasteners from the energy supply before changing the inserted tool or
accessory.
5. Do not touch sockets or accessories during impacting as this increases the risk of cuts, burns or vibration injuries.
6. Use only sizes and types of accessories and consumables that are recommended by the assembly power tool for threaded
fasteners manufacturer; do not use other types or sizes of accessories and consumables.
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 lter 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 or British Standard Pipe. 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 ttings should have the same inside dimensions.
