INJURY HAZARD!

•  This tool has high-speed, highly abrasive cutting surfaces which can quickly 

cause severe injury. Keep fingers and hands away from moving parts when 
operating. Wear thick, well-fitting work gloves and keep loose clothing, 
sleeves, cords, jewelry and hair away from moving parts.

•  This tool will eject a trail of sparks at high speed which can ignite flammable 

materials or injure others nearby. Do not operate in the vicinity of flammable 
materials and keep all persons and pets away from the work area.

•  Do not force tool or exert side forces on Cut-Off Wheel while cutting as 

the tool body can suddenly kick back or twist causing severe hand or wrist 
injury. Cut-Off Wheels can shatter with excessive side force causing them to 
disintegrate and eject sharp pieces at high velocity.

•  Always disconnect tool from air supply when installing or replacing Cut-Off 

Wheels to prevent accidental tool starting and potential severe injury.

•  Always make sure the workpiece being cut is securely clamped or anchored 

to avoid sudden movements which could result in injury.

•  Frequently inspect Cut-Off Wheel and tool condition. If cracks or chips de-

velop, discontinue tool use immediately and replace damaged Wheel. ONLY 
USE replacement Wheels rated at 15,000 RPM or greater. Severe injury can 
result in the event of Cut-Off Wheel failure.

physical injury. Wear thick, well-fitting work gloves when operating. Discon-
tinue use immediately and seek medical attention if numbness or tingling is 
present.
