Warranty  

Products Manufactured by Terra

: Terra Universal, Inc., warrants products that it manufactures to be free  from defects for a 

period of 12 months for parts and 90 days for labor, commencing from the date of shipment. This limited warranty covers parts 
and labor, but not transportation and insurance charges. Terra’s sole responsibility is to repair or replace, at its option, any part of 

the  product  that  proves  defective  or  malfunctioning  during  this  time  limit.  In  some  cases,  components  incorporated  in  Terra 
Universal products are covered by additional warranties from component manufacturers; obtain specific information from Terra 

sales  representatives.  Repairs  may  be  completed  by  3rd  party  service  agents  approved  by  Terra  Universal.  Terra  Universal 
reserves  the  rights  to  limit  this  warranty  based  on  a  service  agent’s  travel,  working  hours,  the  site’s  entry  restrictions  and 
unobstructed access to serviceable components of the product. This warranty is void if the equipment is abused or modified by 

the customer, is operated outside Terra’s operating instructions or specifications, or is used in any application other than that for 
which it is specified. This warranty does not include routine maintenance or service procedures, shipping damage, nor damage 
from misuse, intentional or unintentional abuse, neglect, natural disasters, or acts of God. 

Products  Manufactured  by  Others:  Terra  Universal,  Inc.,  warrants  that,  to  the  best  of  its  ability,  Terra’s  representations  of 
products  that  are  manufactured  by  others  reflect  the  manufacturer’s  representations,  subject  to  change  without  notice.  Sole 

warranty for these products is the original manufacturer’s warranty that is passed forward to the purchaser and constitutes the 
customer’s  sole  remedy  for  these  products.  Detailed  warranties  for  distributed  products  are  available  through  Terra  sales 
representatives. 

Freight Shortage or Damage

: Upon receipt of any equipment from Terra Universal, Inc., customer shall immediately unpack 

and inspect for damage or shortage. The customer shall not accept a damaged package or a short shipment until the carrier 
makes a "damage or shortage" notation on both the carrier's and customer's copy of the freight bill or delivery receipt. Service 
title passes when the shipment is loaded, so customer is responsible for filing and collecting a freight claim. Any replacement 

products must be ordered and paid for separately. For Terra's "Policy and Procedures for Returning Goods," see Terra's Internet 
site: www.TerraUniversal.com. 

Generally,  customers  can  improve  the  chance  of  collecting  on  a  freight  claim  by  following  these  procedures:  1)  formally 
requesting that the carrier inspect the shipment immediately upon suspecting damage or shortage to verify condition; 2) notifying 
the carrier upon discovery of concealed damage and requesting an inspection within 15 days of receipt, both in person or phone 
and following up via mail; 3) keeping the shipment as intact as  possible, including retaining original packaging materials and 
keeping the product as close to the original receiving location as possible; 4) holding salvage for disposition by the carrier. 

All Claims

warranties  of  merchantability  or  fitness  for  intended  use.  Terra  Universal  is  not  responsible  for  consequential  or  incidental

Universal’s total liability for any and all damages whatsoever is limited to the lesser of the actual damages or the original invoice 

cost  of  the  items  alleged  to  have  caused  the  damage.  The  customer’s  sole  and  exclusive  remedy  for  any  cause  of  action 
whatsoever is repair or replacement of the non-conforming products or refund of the actual purchase price, at the sole option of 
Terra Universal. All claims must be made in writing within 90 days of the date the product was shipped. Any claims not made 

within this time limit shall be deemed waived by the customer. Terra Universal is not responsible for any additional costs of repair 
caused by poor packaging or in-shipment damage during return. 

Warranty Returns

approved in advance for good reason, all returns must be in original condition, including all manuals, and must be packaged in 

original packaging materials. All returned goods are to be shipped to Terra Universal, freight prepaid at customer’s expense. See
