WARNING
① The CONTROLLER is not a hand tool. It is designed to be used on a CNC lathe or special
purpose machines.
② Do not touch the cutting tool while the spindle and tool are rotating. It is very dangerous.
③ Wear safety glasses, dust mask, and use a protective cover around the motor spindle whenever
the motor spindle is rotating.
④ Never connect, disconnect or touch the Power Cord Plug or Motor Cord Plug with wet hands.
This may cause an electric shock.
⑤ Never operate or handle the CONTROLLER and motor or spindle until you have thoroughly
read the Operation Manuals and safe operation has been con rmed.
1 ） To prevent injuries / damages, check the CONTROLLER, motor spindle and cutting tool for
proper installation, then operate the CONTROLLER, motor and spindle.
2 ） Before disconnecting the CONTROLLER or 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 CONTROLLER and motor spindle.
⑥ Do not use in dangerous environments. Protect the CONTROLLER from moisture and other
contaminants. Failure to protect CONTROLLER can result in damage to internal components
and injury to the operator.
⑦ Reduce the risk of unintentional starting. Make sure the Main Power Switch is in the OFF position
before connecting the CONTROLLER or plugging the system in.
⑧ The plug must plugged matching outlet that is properly installed and grounded in accordance
with all local codes and ordinances.
⑨ Check to ensure that the supply voltage is the same as the CONTROLLER rated voltage.
⑩ 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.
⑪ 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.
⑫ Do not exceed the maximum recommended allowable tool speed. For your safety, use speeds
below the maximum allowable speed.
⑬ Do not apply excessive force. This may cause tool slippage, tool damage, and injury to the
operator, loss of concentricity and precision.
⑭ When installing the motor and the spindle, make sure the Main Power Switch of the
CONTROLLER turned OFF before installing.
⑮ When installing a motor spindle to a xed base, make sure the xed base is grounded in order
to avoid the risk of an electric shock.
CAUITION
① A motor cooling and spindle purge air is required to operate the system correctly.
The input air line must be connected to the air inlet joint on the front of the CONTROLLER.
Air pressure between 0.25 - 0.3MPa (36.3 - 43.5psi) must be supplied.
② The brushless motor spindle requires air for cooling and purging. Ensure that this air supply
is clean and dry. Introduction of dust, moisture and other contaminants into the CONTROLLER
and motor spindle will cause damage to the internal components.
③ If water or oil is allowed to enter the CONTROLLER, failure of the CONTROLLER may result.
④ Do not hit, drop or subject the motor spindle or CONTROLLER to any type of shock. This will
cause damage to internal components and result in a malfunction.
⑤ Do not disassemble, modify or attempt to repair the CONTROLLER or motor spindle as it will
damage internal components. There are no user serviceable parts available.
⑥ Never place the air vents upward or block the air vents of the CONTROLLER when installing.
⑦ Motor will make a sudden stop when Error LED lights or error output signal is generated.
Check and correct the cause of the malfunction before continuing use. Failure to correct the
problem will result in damage to the CONTROLLER and motor spindle.
