WARNING
①This motor spindle is not a hand tool. It is designed to be used on CNC machines or special purpose machines.
②Do not touch the cutting tool while it is running. It is very dangerous.
③Wear safety glasses, dust mask and use a protective cover around the motor spindle whenever the motor spindle
is rotating.
④Never connect, disconnect or touch the Power Cord Plug and Motor Cord Plug with wet hands. This may cause an
electric shock.
⑤Never operate or handle the motor spindle until you have thoroughly read the owner's manual 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.
⑥When 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.
⑦ Do not use bent, broken, chipped, out of round or sub-standard tools as they may cause shatter or explode. Tool
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.

①Do not drop or hit this motor spindle, as shock can damage to the internal components.
②Be sure to clean the collet and collet nut, the inside of the spindle before replacing the tool. If ground particles or
metal chips stick to the inside of spindle or the collet, damage to the collet or spindle can occur due to the loss of
precision.
③When cleaning a motor spindle, stop the motor spindle and remove debris with a soft brush or a cloth. Do not blow
air into the dust proof cover area (refer to section 6 - 2 " Outside view ") with compressed air as foreign particles
or cutting debris may get into the ball bearing.
④Always clean the tool shank before installing the tool in the spindle.
⑤When sizing the correct collet size to the tool shank diameter, a tolerance of + 0 ~
-
0.01mm is strongly
recommended. A tool shank within the + 0 ~
-
0.1mm range is mountable, however, this may cause poor
concentricity and or insufficient tool shank gripping force.
CAUTION
⑧Do not exceed the maximum recommended allowable tool speed. For your safety, use speeds below the maximum
allowable speed.
⑨Do not apply excessive force. This may cause tool slippage, tool damage, injury to the operator or loss of
concentricity and precision.
