1.1 INTRODUCTION
This service manual provides general directions for
accomplishing service and repair procedures. Following
the procedures in this manual will help assure safety and
equipment reliability.
Read, understand and follow the information in this
manual, and obey all locally approved safety practices,
procedures, rules, codes, regulations and laws.
These instructions cannot cover all details or variations in
the equipment, procedures, or processes described, nor
provide directions for meeting every possible contingency
during operation, maintenance, or testing. When additional
information is desired consult the local distributor.
Many factors contribute to unsafe conditions: carelessness,
fatigue, overload, inattentiveness, unfamiliarity, even
drugs and alcohol, among others. For optimal safety,
encourage everyone to think, and to act, safely.
Appropriate service methods and proper repair
procedures are essential for the safety of the individual
doing the work, for the safety of the operator, and for the
safe, reliable operation of the machine.
All references to
the right side, left side, front and rear are given from the
operator’s seat looking in a forward direction.
Supplementary information is available from JLG in the
form of Service Bulletins, Service Campaigns, Service
Training Schools, the JLG website, other literature, and
through updates to the manual itself.

Manual is missing, consult the local distributor before
proceeding.

To avoid possible death or injury, carefully read,
