WARNING
HEAVY OBJECT. EXTREME CAUTION SHOULD BE EXERCISED WHEN

The following procedures align the top of the product to the top surface of the
top plates. A reference check is made using the setting bar (201121). The
shim and pallet assembly used for these checks should be those used for a
customer production product.
Reference Check NOTE
The precision pallet, shim, rail top plates and setting bar are all manufactured
to a high degree of flatness and are susceptible to surface flaws that can
degrade their function. In the following procedure hard tooling is used in
contact with these surfaces which may cause markings or more significant
damage, if not handled carefully. Tooling used must be clean and blemish
free. All effort must be made to avoid dragging, dropping or knocking tools on
the exposed surfaces.
For many instances, this check gives the level of accuracy required to produce
good quality prints; for the highest accuracy, carry out this check and the
accuracy check, refer to the section - Accuracy Check for details.
