CAUTION
When not using NAKANISHI Air Line Kit, make sure that the incoming air supply is dry, clean and
properly regulated.
CAUTION
・The Air input joint, is designed to accept cooling air between 0.2 - 0.35MPa (29.0 - 50.8psi). If the
air pressure is too low, the CONTROLLER will not operate and an Error code will be generated.
Set the air pressure 0.35MPa (50.8psi) when using the motor spindle for continuous use.
・The cooling air also provides air purge protection to the motor spindle. If the Main Power Switch
is turned OFF, the cooling air will continue to Àow.
・Do not make any sharp bends in the air hose, or pull on the hose as this can cause the hose to
break, cut off the air supply or weaken the hose over time resulting in deterioration of the motor
and spindle.
・Never supply over regulated air pressure. There is a possibility to damage to the air detection
sensor inside the CONTROLLER.
・The air detect function within the CONTROLLER detects air input supply only. If the Air Out hose
is damaged from the CONTROLLER, it will not be able to detect the lack of cooling and purging
air to the motor spindle.
