Safety Instructions for Machinery

OWNER’S MANUAL. read and understand this owner’s manual BeFore using machine.

TRAINED OPERATORS ONLy. untrained oper- ators have a higher risk of being hurt or killed. only allow trained/supervised people to use this machine. When machine is not being used, dis- connect power, remove switch keys, or lock-out machine to prevent unauthorized use—especially around children. Make workshop kid proof!

DANGEROUS ENVIRONMENTS. do not use machinery in areas that are wet, cluttered, or have poor lighting. operating machinery in these areas greatly increases the risk of accidents and injury.

MENTAL ALERTNESS REQUIRED. Full mental alertness is required for safe operation of machin- ery. never operate under the influence of drugs or alcohol, when tired, or when distracted.

ELECTRICAL EQUIPMENT INJURy RISKS. you can be shocked, burned, or killed by touching live electrical components or improperly grounded machinery. to reduce this risk, only allow qualified service personnel to do electrical installation or repair work, and always disconnect power before accessing or exposing electrical equipment.

DISCONNECT POWER FIRST. Always discon- nect machine from power supply BeFore making adjustments, changing tooling, or servicing machine. this prevents an injury risk from unintended startup or contact with live electrical components.

EyE PROTECTION. Always wear Ansi-approved safety glasses or a face shield when operating or observing machinery to reduce the risk of eye injury or blindness from flying particles. everyday eyeglasses are not approved safety glasses.
