1 stages may be equipped with Levin “Type-D” style collets. It is important that only the collets
designed for a particular collet holder are used. Contact the factory for more details.

Various grip diameters are commonly available and can be interchanged.
2.8.1. Collet Installation and Removal Procedure
D A N G E R : To minimize the possibility of bodily injury or death, disconnect all electrical
power prior to performing any maintenance or making adjustments to the equipment.
Step 1: Remove power to the stage before installing or removing the collet.
Step 2: Turn off air pressure to expose front of collet in chuck.
Step 3: Remove the collet from the chuck. While unthreading the collet, there will possibly be slight
resistance and a clicking sound. The resistance and clicking is caused by [QTY-3] spring loaded ball
end set screws that help prevent the collet from unthreading during stage operation. The ball end
drops in and out of the collet’s detent as it is turned.
Step 4: For installation of a collet, first clean the chuck taper, and new collet including threads. Acetone or
isopropyl alcohol may be used to clean the metal components. A small amount of any general-
purpose, high viscosity grease can be applied to the collet taper to help reduce friction and decrease
wear.
Step 5: Guide the collet into the stage (
) and thread into collet taper. Be sure that air pressure is
still not being supplied to the stage so the collet chuck remains in the open position.

Installation Procedure for Collet
Step 6: Insert the desired part into the collet. Actuate the collet chuck by applying air pressure to verify that
the collet is clamping the part. Adjust collet threaded depth as required.
Step 7: Restore power to the stage.
