. REPLACING THE COLLET HOLDER
WARNING
・
When replacing the collet holder, be sure to stop the Motor. If the collet holder
replaced while the motor is rotating, the Spindle will incur internal damage.
・
When collet holder is not attached to the Spindle, do not turn ON / OFF of the air
operation. Because this will cause damage to the Spindle or loss of precision.
CAUTION
・
When the air is supplied to the inlet joint of the Spindle, the collet holder
will be pushed out by exhausting the coolant air of brushless motor from
the edge of Spindle. Be careful not to be damaged to the tool or be injured.
・
Use the air ON / OFF valve through which the air can be exhausted. Do not
use 2 way valve, because the 2 way valve is not exhausted and the collet is
not closed.
