Uncrate the S
TU as follows:
1. Inspect the crate for shipping damage. Contact
the carrier if damaged.
2. Remove plywood top and sides of crate.
3. Check the contents for loose or damaged parts.
4. Compare the packing slip against items inside
the crate. Immediately call your Graco distributor
about any shortages or damage.
5. Remove all band straps.
6. Remove the clevis pins holding the rear gate and
remove the gate.
7. Remove the bolts holding the frame parts and
move to the installation location.
NOTE: Use sanitary anti-sieze (provided) on all
threaded joints to prevent galling.
NOTE: Wh
en installing, the crossbar (1–R) must
be orien
ted with the safety latch bracket facing
the leg
assembly which doesn’t contain the
contro
l panel. This orientation is also necessary
to allo
w proper installation of the rigid air line from
the pil
