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 mak-

ing adjustments, changing tooling, or servicing

machine. This prevents an injury risk from unin-

tended startup or contact with live electrical com-

ponents.

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.

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 your 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.

For Your Own Safety, Read Instruction

Manual Before Operating This Machine

The purpose of safety symbols is to attract your attention to possible hazardous conditions.

This manual uses a series of symbols and signal words intended to convey the level of impor-

tance of the safety messages. The progression of symbols is described below. Remember that

safety messages by themselves do not eliminate danger and are not a substitute for proper

accident prevention measures. Always use common sense and good judgment.

Indicates a potentially hazardous situation which, if not avoided,
MAY result in minor or moderate injury. It may also be used to alert
against unsafe practices.

Indicates a potentially hazardous situation which, if not avoided,
COULD result in death or serious injury.

Indicates an imminently hazardous situation which, if not avoided,
WILL result in death or serious injury.

Alerts the user to useful information about proper operation of the
machine to avoid machine damage.
