WEARING PROPER APPAREL. do not wear clothing, apparel or jewelry that can become entangled in moving parts. Always tie back or cover long hair. Wear non-slip footwear to avoid accidental slips, which could cause loss of work- piece control.

HAzARDOUS DUST. dust created while using machinery may cause cancer, birth defects, or long-term respiratory damage. Be aware of dust hazards associated with each workpiece material, and always wear a niosh-approved respirator to reduce your risk.

HEARING PROTECTION. Always wear hear- ing protection when operating or observing loud machinery. extended exposure to this noise without hearing protection can cause permanent hearing loss.

REMOVE ADJUSTING TOOLS. tools left on machinery can become dangerous projectiles upon startup. never leave chuck keys, wrenches, or any other tools on machine. Always verify removal before starting!

USE CORRECT TOOL FOR THE JOb. only use this tool for its intended purpose—do not force it or an attachment to do a job for which it was not designed. never make unapproved modifica- tions—modifying tool or using it differently than intended may result in malfunction or mechanical failure that can lead to personal injury or death!

AWKWARD POSITIONS. Keep proper footing and balance at all times when operating machine. do not overreach! Avoid awkward hand positions that make workpiece control difficult or increase the risk of accidental injury.

CHILDREN & bySTANDERS. Keep children and bystanders at a safe distance from the work area. stop using machine if they become a distraction.

GUARDS & COVERS. guards and covers reduce accidental contact with moving parts or flying debris. Make sure they are properly installed, undamaged, and working correctly.

FORCING MACHINERy. do not force machine. it will do the job safer and better at the rate for which it was designed.

NEVER STAND ON MACHINE. serious injury may occur if machine is tipped or if the cutting tool is unintentionally contacted.

STAbLE MACHINE. unexpected movement dur- ing operation greatly increases risk of injury or loss of control. Before starting, verify machine is stable and mobile base (if used) is locked.

USE RECOMMENDED ACCESSORIES. Consult this owner’s manual or the manufacturer for rec- ommended accessories. using improper acces- sories will increase the risk of serious injury.

UNATTENDED OPERATION. to reduce the risk of accidental injury, turn machine OFF and ensure all moving parts completely stop before walking away. never leave machine running while unattended.

MAINTAIN WITH CARE. Follow all maintenance instructions and lubrication schedules to keep machine in good working condition. A machine that is improperly maintained could malfunction, leading to serious personal injury or death.

CHECK DAMAGED PARTS. regularly inspect machine for any condition that may affect safe operation. immediately repair or replace damaged or mis-adjusted parts before operating machine.

MAINTAIN POWER CORDS. When disconnect- ing cord-connected machines from power, grab and pull the plug—not the cord. pulling the cord may damage the wires inside. do not handle cord/plug with wet hands. Avoid cord damage by keeping it away from heated surfaces, high traffic areas, harsh chemicals, and wet/damp locations.

EXPERIENCING DIFFICULTIES. if at any time you experience difficulties performing the intend- ed operation, stop using the machine! Contact our technical support at (570) 546-9663.
