Daily Walk-Around Inspection - Sheet 2 Of 3 - JLG 450A Operator's And Safety Manual

GENERAL
Begin the "Walk-Around Inspection" at Item 1, as noted on
the diagram. Continue to the right (counterclockwise
viewed from top) checking each item in sequence for the
conditions listed in the Walk-Around Inspection Checklist.
TO AVOID INJURY, DO NOT OPERATE A MACHINE UNTIL ALL

side. Checking this area often results in discovery of
conditions which could cause extensive machine
damage.
