Preface
Congratulations! You have purchased a precision vacuum positioning device
from Nor -Cal Products. This unit is capable of many years of use with minimal
care and maintenance. This manual is a tool to aid you in obtaining this service.
We at Nor-Cal Products encourage your comments and suggestions on this
manual.

Product Description
The PMXYZ series precision manipulators are a family of aluminum units which
offer exceptional value per dollar. The PMXYZ series feature pre-loaded cross
roller X & Y stages. The 2" Z travel model with the 1.39" ID bellows has a
Micrometer drive.

The PMXYZ series are available with greater Z axis travel and larger bellows.
The PMXYZ Series instruments have a 20# equipment payload for vertical

operation. For applications which need different payloads and/or other
operational orientations, please consult the factory. See "installation" section
below for complete payload considerations.

A full compliment of options are available... many suitable for field retrofit. This
allows the unit to be modified to suit changing requirements as the role for the
manipulator changes through its life.

Unpacking
PMXYZ manipulators are shipped in custom foam-in-place packing. We have
found this the only system to provide adequate protection for shipment. The
foam is separated approximately half way inside the crate with thin blue plastic.
The bellows assembly is shipped in place protected by a cardboard or thick
paper wrap about the bellows. This wrap should be left in place until the
manipulator is fully mounted. We strongly recommend the packing be saved for
possible future shipment or equipment storage.

Installation

******** WARNING *********
Shipping vibration can loosen screws. The user must check to verify the screw

fasteners have not backed off on the unit during shipment. This is critical for safe
operation.

***********THIS IS IMPORTANT ************
The standard PMXYZ Manipulator can be installed directly from the packing. As

usual, care should be exercised to protect the knife seal edge. The standard
units mount to a 2.75" or 6" OD flange. Proper tightening technique should be
observed whenever tightening a metal sealed flange. We recommend a small
quantity of high temperature anti -seize lubricant be used on all mounting bolts.
This is especially import ant if the unit will be subject to bake-outs.

********** WARNING *********

It is necessary, especially on longer stroke manipulators, to have an axis rod or
tube down the axis of the Z travel. This will keep the bellows from "springing" out
when the pressure is returned to atmosphere (usually when the unit is near its
most compressed mode). This function is usually satisfied by a "theta" rotation
shaft or support tube. Damage to the equipment can occur if this precaution is
not observed.
