2.1 REPLACEMENT PARTS AND
WARRANTY INFORMATION
Before ordering parts or initiating service inquiries, make
note of the machine serial number. The machine serial
number plate (1) is located as indicated in the figure.
Note: The replacement of any part on this machine with
any other than JLG authorized replacement parts can
adversely affect the performance, durability, or safety of
the machine, and will void the warranty. JLG disclaims
liability for any claims or damages, whether regarding
property damage, personal injury or death arising out of
the use of unauthorized replacement parts.
A warranty registration form must be filled out by the JLG
distributor, signed by the purchaser and returned to JLG
when the machine is sold and/or put into use.
Registration activates the warranty period and helps to
assure that warranty claims are promptly processed. To
guarantee full warranty service, verify that the distributor
has returned the business reply card of the warranty
registration form to JLG.
