MACHINE PREPARATION, INSPECTION, AND
MAINTENANCE
General
This section provides the necessary information needed by
those personnel that are responsible to place the machine in
operation readiness and maintain its safe operating condition.
For maximum service life and safe operation, ensure that all
the necessary inspections and maintenance have been com-
pleted before placing the machine into service.
With proper care, maintenance, and inspections performed
per JLG's recommendations, and with any and all discrepan-
cies corrected, this product will be fit for continued use.
Preparation, Inspection, and Maintenance
It is important to establish and conform to a comprehensive
inspection and preventive maintenance program. The follow-
ing table outlines the periodic machine inspections and main-
tenance recommended by JLG Industries, Inc. Consult your
national, regional, or local regulations for further requirements
for aerial work platforms. The frequency of inspections and
maintenance must be increased as environment, severity and
frequency of usage requires.
Pre-Start Inspection
It is the User’s or Operator’s primary responsibility to perform a
Pre-Start Inspection of the machine prior to use daily or at
each change of operator. Reference the Operator’s and Safety
Manual for completion procedures for the Pre-Start Inspec-
tion. The Operator and Safety Manual must be read in its
entirety and understood prior to performing the Pre-Start
Inspection.
Pre-Delivery Inspection and Frequent Inspection
The Pre-Delivery Inspection and Frequent Inspection shall be
performed by a qualified JLG equipment mechanic. JLG Indus-
tries, Inc. recognizes a qualified JLG equipment mechanic as a
person who, by possession of a recognized degree, certificate,
extensive knowledge, training, or experience, has successfully
demonstrated the ability and proficiency to service, repair, and
maintain the subject JLG product model.
The Pre-Delivery Inspection and Frequent Inspection proce-
dures are performed in the same manner, but at different
times. The Pre-Delivery Inspection shall be performed prior to
each sale, lease, or rental delivery. The Frequent Inspection
shall be accomplished for each machine in service for 3
months or 150 hours (whichever comes first); out of service for
a period of more than 3 months; or when purchased used. The
frequency of this inspection must be increased as environ-
ment, severity and frequency of usage requires.

pleted the JLG Service Training School for the subject JLG
product model. Reference the machine Service and Mainte-
nance Manual and appropriate JLG inspection form for perfor-
