・When plumbing the hose, never apply excessive force to the hose as it can easily become bent
or broken. Failure to supply proper air may cause damage to the motor spindle.
・Never supply over the regulated air pressure. There is a possibility to damage to the air
detection sensor inside the SELECTOR.
・The air detect function with the SELECTOR detects air input supply only. If the Air Out hose is
damaged from the SELECTOR, it will not be able to detect the lack of cooling and purging air to
the motor spindle.
