Inspect the equipment immediately upon receipt. If it has been damaged during shipment, keep
the shipping cartons and packing materials and file a claim with your freight carrier and/or
insurance company for shipping damage. If you discover shipping damage

after

acceptance, file

a claim for concealed damage.
