S HIPPING I NSPECTION
All units are securely packed in shipping containers tested
according to International Safe Transit Association specifi-
cations. The carton must be checked upon arrival for ex-
ternal damage. If damage is found, a request for inspec-
tion by carrier’s agent must be made in writing immedi-
ately.
Inspect the kit carefully on arrival for damage and bolts or
screws which may have come loose in transit. In the event
of damage the consignee should:
1. Make a notation on delivery receipt of any visible
damage to shipment or container.
2. Notify carrier promptly and request an inspection.
3. With concealed damage, carrier must be notified as
soon as possible - preferably within five days.
4. File the claim with the following support documents
within a nine month statute of limitations.
• Original or certified copy of the Bill of Lading, or
indemnity bond.
• Original paid freight bill or indemnity in lieu thereof.
• Original or certified copy of the invoice, showing
trade and other discounts or reductions.
• Copy of the inspection report issued by carrier’s
representative at the time damage is reported to
carrier.
The carrier is responsible for making prompt inspection of
damage and for a thorough investigation of each claim. The
distributor or manufacturer will not accept claims from
dealers for transportation damage.
