Receiving
Upon receiving the product, check to ensure all
items are accounted for by referencing the delivery
receipt or packing list. Inspect each crate or carton
for shipping damage before accepting delivery. Alert
the carrier of any damage detected. The customer will
make notation of damage (or shortage of items) on
the delivery receipt and all copies of the bill of lading
which is countersigned by the delivering carrier. If
damaged, immediately contact your representative. Any
physical damage to the unit after acceptance is not the
responsibility of the manufacturer.
Unpacking
Verify that all required parts and the correct quantity
of each item have been received. If any items are
missing, report shortages to your local representative to
arrange for obtaining missing parts. Sometimes it is not
possible that all items for the unit be shipped together
due to availability of transportation and truck space.
Confirmation of shipment(s) must be limited to only
items on the bill of lading.
