LIMITED WARRANTY
Snorkel warrants each new machine manufactured and sold by it to be free from defects in material and workmanship for a
period of one (1) year from date of delivery to a Customer or for one year after the machine has been placed in first service in a
Dealer rental fleet, whichever comes first. Any part or parts which, upon examination by the Snorkel Service Department, are
found to be defective, will be replaced or repaired, at the sole discretion of Snorkel, through its local Authorized Dealer at no
charge.
Snorkel further warrants the structural components; specifically, the mainframe chassis, turntable, booms and scissor arms,
of each new machine manufactured by it to be free from defects in material and workmanship for an additional period of four
(4) years. Any such part or parts which, upon examination by the Snorkel Service Department, are found to be defective will
be replaced or repaired by Snorkel through its local Authorized Dealer at no charge; however, any labor charges incurred as a
result of such replacement or repair will be the responsibility of the Customer or Dealer.
The Snorkel Service Department must be notified within forty-eight (48) hours of any possible warranty situation during the
applicable warranty period. Personnel performing warranty repair or replacement must obtain specific approval by Snorkel
Service Department prior to performing any warranty repair or replacement.
Customer and Dealer shall not be entitled to the benefits of this warranty and Snorkel shall have no obligations hereunder
unless the “Pre-Delivery and Inspection Report” has been properly completed and returned to the Snorkel Service
Department within ten (10) days after delivery of the Snorkel product to Customer or Dealer’s rental fleet. Snorkel must be
notified, in writing, within ten (10) days, of any machine sold to a Customer from a Dealer’s rental fleet during the warranty
period.
At the direction of the Snorkel Service Department, any component part(s) of Snorkel products to be replaced or repaired
under this warranty program must be returned freight prepaid to the Snorkel Service Department for inspection. All warranty
replacement parts will be shipped freight prepaid (standard ground) from the Snorkel Service Department or from Snorkel’s
Vendor to Dealer or Customer.
REPLACEMENT PARTS WARRANTY
Any replacement or service part made or sold by Snorkel is not subject to the preceding Limited Warranty beyond the
normal warranty period of the machine upon which the part was installed.
THIS WARRANTY EXCLUDES AND SNORKEL DOES NOT WARRANT:
1. Engines, motors, tires and batteries which are manufactured by suppliers to Snorkel, who furnish their own warranty.
Snorkel will, however, to the extent permitted, pass through any such warranty protection to the Customer or Dealer.
2. Any Snorkel product which has been modified or altered outside Snorkel’s factory without Snorkel’s written approval, if
such modification or alteration, in the sole judgment of Snorkel’s Engineering and/or Service Departments, adversely
affects the stability, reliability or service life of the Snorkel product or any component thereof.
3. Any Snorkel product which has been subject to misuse, improper maintenance or accident. “Misuse” includes but is
not limited to operation beyond the factory-rated load capacity and speeds. “Improper maintenance” includes but is not
limited to failure to follow the recommendations contained in the Snorkel Operation, Maintenance, Repair Parts
Manuals. Snorkel is not responsible for normal maintenance, service adjustments and replacements, including but not
limited to hydraulic fluid, filters and lubrication.
4. Normal wear of any Snorkel component part(s). Normal wear of component parts may vary with the type application or
type of environment in which the machine may be used; such as, but not limited to sandblasting applications.
5. Any Snorkel product that has come in direct contact with any chemical or abrasive material.
6. Incidental or consequential expenses, losses, or damages related to any part or equipment failure, including but not
limited to freight cost to transport the machine to a repair facility, downtime of the machine, lost time for workers, lost
orders, lost rental revenue, lost profits or increased cost.
This warranty is expressly in lieu of all other warranties, representations or liabilities of Snorkel, either expressed or implied,
unless otherwise amended in writing by Snorkel’s President, Vice President-Engineering, Vice President-Sales or Vice
President-Marketing.
SNORKEL MAKES NO WARRANTIES WHICH EXTEND BEYOND THE DESCRIPTION OF THIS LIMITED WARRANTY.
SNORKEL MAKES NO IMPLIED WARRANTY OF MERCHANTABILITY OR FITNESS FOR A PARTICULAR PURPOSE
AND DISCLAIMS ALL LIABILITY FOR INCIDENTAL OR CONSEQUENTIAL DAMAGES, INCLUDING BUT NOT
LIMITED TO INJURY TO PERSONS OR PROPERTY.
The Customer shall make all warranty claims through its local Authorized Dealer and should contact the Dealer from whom
the Snorkel product was purchased for warranty service. Or, if unable to contact the Dealer, contact the Snorkel Service
Department for further assistance.
