WARNING A safety hazard could result in bodily injury or damage to the device if the 

safety instructions are not properly followed.

  

CAUTION A hazard that could result in light or moderate bodily injury or damage to the device 

if the safety instructions are not followed.

WARNING

This motor spindle is not a hand tool. It is designed to be used on CNC machines or special 

purpose machines.

Do not touch the cutting tool while it is running. It is very dangerous.

Wear safety glasses, dust mask and hearing protection, and use a protective cover around the 

motor spindle whenever the motor spindle is rotating.

Never connect, disconnect or touch the Power Cord Plug and Motor Cord Connector  with wet 

hands. This may cause an electric shock.

Never operate or handle the motor spindle until you have thoroughly read the owner's manual 

and safe operation has been con

rmed.

1)  To  prevent  injuries/damages,  check  this  motor  spindle  and  cutting  tool  for  proper 

installation, then operate this motor spindle.

2) Before disconnecting this motor spindle, always turn the control power off and turn the 

compressed air supply to the control unit off. It is then safe to remove this motor spindle.

When installing a tool, tighten the collet correctly and check again the collet and collet nut 

before use. Do not over-tighten the collet. This may cause damage to the motor spindle.

Do not use bent, broken, chipped, out of round or sub-standard tools as they can shatter or 

explode. It shatters, it cracked, and the tool that bends and breaks disperses and it causing 

injures. When using a new tool, rotate it in a low speed and increase speed gradually for safety.

Do not exceed the maximum recommended allowable tool speed. For your safety, use speeds 

below the maximum allowable speed.

Do not apply excessive force. This may cause tool slippage, tool damage, injury to the 

operator, loss of concentricity and precision.
