states do not allow the exclusion or limitation or incidental or consequential
damages, so the above limitation and exclusion may not apply to you. This
warranty gives you specific legal rights and you may also have other rights
which may vary from state to state.
E-Z Trench Manufacturing Company, Inc. does not warrant the engine but
the purchaser must look to the engine manufacturer for the warranty of the
engine.
NORMAL WEAR:
Warranty will not cover repair where normal use has exhausted the life of a
part. Trenchers, like all mechanical devices, need periodic parts replace-
ment and service to perform well. It should be remembered that the service
life of any trencher is dependent on the care it receives and the conditions
under which it has to operate. Trenchers operate in harsh conditions, which
can cause what appears to be premature wear. Such wear, when caused
by rocks or other abrasive material, is not covered by warranty.
E-Z TRENCH WARRANTY DOES NOT COVER THE FOLLOWING:
1. Bent or broken parts; Such damage is normally the result of abuse,
such as striking a solid object with the cutting blade.
2. Broken parts, which results from excessive vibration caused by loose
engine mounting, loose cutting blades, unbalanced blades, improperly
attaching equipment to trencher, overspeeding or abuse in operation.
3. Misuse, neglect, improper operation, damage or abuse.
4. Alteration or removal of name plates or serial numbers.
5. Modification or change of this product outside the factory.
STANDARD TERMS:
1. C.O.D./F.O.B., Loris, SC, USA
2. Cash, money order, certified check, or wire transfer with order.
3. 30 day with approved credit.
All sales are final with no right to return, price protection or implied con-
signment. No person, including agent, representative, or employee of E-Z
TRENCH MANUFACTURING, Inc. is authorized to assume for E-Z
TRENCH MANUFACTURING, Inc. any obligation or liability concerning
terms or conditions of sale other than that expressly stated herein.
