This Brushless Motor Spindle is not a hand tool. It is designed to be used on CNC machines or 
special purpose machines.

Do not exceed the " Maximum Allowable Motor Rotation Speed " (Refer to " 6 - 1  Specications "). 
An excess of the Maximum Allowable Motor Rotation Speed may cause damage to the inside 
components and short life.

Do not touch the cutting tool while it is running. It is very dangerous.

Wear safety glasses, dust mask, and use a protective cover around the Brushless Motor Spindle 
whenever the Brushless Motor Spindle is rotating.

Never connect, disconnect or touch the Power Cord Plug or Motor Cord Plug with wet hands. This 
may cause an electric shock.

Never operate or handle the Brushless Motor Spindle until you have thoroughly read the Operation
