Additional Safety for Mills/Drills

The primary risks of operating a Mill/Drill are as follows: You can be seriously injured or killed by getting clothing, jewelry, or long hair entangled with rotating cutter. You can be severely cut or your fingers can be amputated by contacting the rotating cutter. You can be blinded or struck with great force by broken cutting tools, metal chips, workpieces, or adjustment tools thrown from the rotating spindle. To reduce your risk of serious injury when operating this machine, completely heed and understand the following:

UNDERSTAND ALL CONTROLS. Make sure you understand the function and proper use of all con- trols before starting. This will help you avoid mak- ing mistakes that result in serious injury.

WEAR FACE SHIELD. Always wear a face shield in addition to safety glasses. This provides more complete protection for your face than safety glasses alone.

REMOVE CHUCK KEY & SPINDLE TOOLS. Always remove chuck key, drawbar wrench, and other tools used on the spindle immediately after use. This will prevent them from being thrown by the spindle upon startup.

PROPERLY SECURE CUTTER. Firmly secure cutting tool or drill bit so it does not fly out of spin- dle during operation.

USE CORRECT SPINDLE SPEED. Follow rec- ommended speeds and feeds for each size and type of cutting tool. This helps ensure best cutting results and avoid tool breakage during operation.

INSPECT CUTTING TOOL. Inspect cutting tools for sharpness, chips, or cracks before each use. Replace dull, chipped, or cracked cutting tools immediately.

ALLOW SPINDLE TO STOP. To minimize your risk of entanglement, always allow spindle to stop on its own. DO NOT stop spindle using your hand or any other object.

SECURE WORKPIECE TO TABLE. Clamp workpiece to table or secure in a vise mounted to table, so workpiece cannot unexpectedly shift or spin during operation. NEVER hold workpiece by hand during operation.

CLEAN MACHINE SAFELY. Metal chips or shav- ings can be razor sharp. DO NOT clear chips by hand or compressed air that can force chips farther into machine—use a brush or vacuum instead. Never clear chips while spindle is turning.

PROPERLY MAINTAIN MACHINE. Keep machine in proper working condition to help ensure that it functions safely and all guards and other compo- nents work as intended. Perform routine inspec- tions and all necessary maintenance. Never oper- ate machine with damaged or worn parts that can break or result in unexpected movement during operation.

DISCONNECT POWER FIRST. To reduce risk of electrocution or injury from unexpected startup, make sure mill/drill is turned OFF, disconnected from power, and all moving parts have come to a complete stop before changing cutting tools or starting any inspection, adjustment, or mainte- nance procedure.

POWER DISRUPTION. In the event of a local power outage during operation, turn spindle switch OFF to avoid a possible sudden startup once power is restored.

Like all machinery there is potential danger when operating this machine. Accidents are fre- quently caused by lack of familiarity or failure to pay attention. Use this machine with respect and caution to lessen the possibility of operator injury. If normal safety precautions are over- looked or ignored, serious personal injury may occur.
