 Read these warnings and cautions carefully and only use in the manner intended.

 These warnings and cautions are intended to avoid potential hazards that could result in personal injury to the 

operator or damage to the device. These are classified as follows in accordance with the seriousness of the risk.

Class

Degree of Risk

 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.

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 use a protective cover around the Spindle whenever the Spindle 

is rotating.

Never connect, disconnect or touch the Power Cord Plug or Motor Cord Plug with wet hands. This 

may cause an electric shock.

Never operate or handle the Motor Spindle until you have thoroughly read the Operation Manuals 

and safe operation has been confirmed.

1)  To prevent injuries / damages, check the Motor Spindle and cutting tool for proper installation, 

before operating the Motor Spindle. 

2)  Before disconnecting the Motor Spindle, always turn the control power off and turn the 

compressed air supply to the CONTROLLER off. Then it is safe to remove the Motor Spindle.

Whenever installing a Motor Spindle to a fixed metal base, ensure that the fixed metal base is 

grounded in order to avoid risk of an electric shock. 

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 spindle.

Do not use bent, broken, chipped, out of round or sub-standard tools, as this may cause them to 

shatter or explode. Tools with fractures or a bent shank will cause injury to the operator. When using 

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

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

below the maximum allowable speed. 

Do not apply excessive force. This may cause injury to the operator by slippage or damage of 

the tool, or loss of concentricity and precision of the Motor Spindle.
