SECTION 2. GENERAL
2.1 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 completed before placing the
machine into service.
Preparation, Inspection, and Maintenance
It is important to establish and conform to a comprehen-
sive inspection and preventive maintenance program. The
following table outlines the periodic machine inspections
and maintenance recommended by JLG Industries, Inc.
Consult your national, regional, or local regulations for fur-
ther 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 per-
form a Pre-Start Inspection of the machine prior to use
daily or at each change of operator. Reference the Opera-
tor’s and Safety Manual for completion procedures for the
Pre-Start Inspection. The Operator and Safety Manual
must be read in its entirety and understood prior to per-
forming 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 Industries, Inc. recognizes a qualified JLG equipment
mechanic as a person who, by possession of a recog-
nized 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 pro-
cedures are performed in the same manner, but at differ-
ent 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 ser-
vice 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 environment, severity and frequency of
usage requires.
Reference the JLG Pre-Delivery and Frequent Inspection
Form and the Inspection and Preventative Maintenance
Schedule for items requiring inspection during the perfor-
mance of these inspections. Reference the appropriate
areas of this manual for servicing and maintenance proce-
dures.
Annual Machine Inspection
The Annual Machine Inspection must be performed by a
Factory-Certified Service Technician on an annual basis,
no later than thirteen (13) months from the date of the
prior Annual Machine Inspection. JLG Industries, Inc. rec-
ognizes a Factory-Certified Service Technician as a per-
son who has successfully completed the JLG Service
Training School for the subject JLG product model. Refer-
ence the machine Service and Maintenance Manual and
appropriate JLG inspection form for performance of this
inspection.
Reference the JLG Annual Machine Inspection Form and
the Inspection and Preventative Maintenance Schedule for
items requiring inspection during the performance of this
inspection. Reference the appropriate areas of this man-
ual for servicing and maintenance procedures.
For the purpose of receiving safety-related bulletins, it is
important that JLG Industries, Inc. has updated ownership
information for each machine. When performing each
Annual Machine Inspection, notify JLG Industries, Inc. of
the current machine ownership.
Preventative Maintenance
In conjunction with the specified inspections, mainte-
nance shall be performed by a qualified JLG equipment
mechanic. JLG Industries, Inc. recognizes a qualified JLG
equipment mechanic as a person who, by possession of a
recognized degree, certificate, extensive knowledge, train-
ing, or experience, has successfully demonstrated the
ability and proficiency to service, repair, and maintain the
subject JLG product model.
Reference the Preventative Maintenance Schedule and
the appropriate areas of this manual for servicing and
maintenance procedures. The frequency of service and
maintenance must be increased as environment, severity
and frequency of usage requires.
