3M Die Grinder 28627 Pneumatic Power 0.3 Hp Motor 1/4″ Collet 18000 rpm USA

The Die Grinder 28627 requires a clean lubricated air supply that will give a measured air pressure at the tool of 6.2 bar (90 psi) when the tool is running with the lever fully depressed so the maximum RPM is not exceeded. The tool can be run at lower pressures but should never be run higher than 6.2 bar (90 psi). If run at a lower pressure the performance of the tool is reduced. For pneumatic power to the tool, an approved 10 mm (3/8 inch) x 8 m (25 feet) maximum length airline is recommended. The tool must be connected to an airline system with an easily accessible air shut off valve. It is strongly recommended that an air filter, regulator, and lubricator (FRL) be used to supply clean, lubricated air at the correct pressure to the tool. An appropriate air pressure regulator must be used at all times while operating this tool when the supply pressure exceeds the marked maximum of the tool, 18,000 RPM. If such equipment is not used, the tool should be manually lubricated. For instructions on connecting the tool to the air supply and manually lubricating the tool, see the Instruction Manual.
