INTRODUCTION
JLG Industries, Inc. (hereafter, JLG) actively promotes
safe practices in the use and maintenance of its products
through training programs, instructional manuals and the
pro-active efforts of all employees involved in engineering,
design, manufacture, marketing and service.
This manual is designed to provide service technicians
with complete information on the maintenance and repair
of the Lull 644E-42 and 944E-42 Telescopic Material
Handler.
Particular effort has been made to produce a manual to
serve as a reference handbook for the experienced
service technician, but also provide essential step-by-
step procedures for the professional development of the
less experienced person. Remember, even the best
manual in the world is no substitute for an appropriate
education, skill development that comes through
experience alone, safety, wise and judicious
discernment, and ultimately, proper performance of
service procedures.
This service manual provides general directions for
accomplishing service and repair procedures with tested,
effective techniques. 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. Prior to
performing any maintenance on the vehicle, consider all
factors, circumstances and conditions which can have an
effect upon the safety of personnel and equipment, and
take appropriate action to ensure the safety of all
involved.
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 to satisfy a situation not
covered sufficiently, consult your local Lull distributor or
the JLG Service Department at (877) 554-5438 or
(717) 485-6657.
Many factors contribute to unsafe conditions;
carelessness, fatigue, overload, inattentiveness,
unfamiliarity, even drugs and alcohol, among others.
Although equipment damage can usually be repaired in a
brief period of time, death and irreparable injury are
permanent. 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 vehicle.
All references to the right side, left side, front, and rear
are given from the operator’s seat looking in a forward
direction.
Provisions for supplementary information are made by
JLG in the form of Service Bulletins, Service Campaigns,
Service Training Schools, the JLG web site, other
literature, and through updates to the manual itself.
Comments and suggestions for improvement are
welcome and encouraged.
All information, illustrations and specifications contained
in this manual are based on the latest product information
available at the time of publication approval. JLG
reserves the right to make changes and improvements to
its products, and to discontinue the manufacture of any
product, at its discretion at any time without public notice
or obligation.

OWNERS/OPERATORS MANUAL
The vehicle must be driven and operated as a
consequence of performing service, maintenance and
test procedures. The service technician must therefore
read, understand and follow the instructions in the Lull
644E-42 and 944E-42 Telescopic Material Handler
Owners/Operators Manual.
An Owners/Operators and AEM Safety Manuals are
supplied with each vehicle and must be kept in the
pouch (1) on the back of the drivers seat.
In the event that the Owners/Operators or Safety
Manuals are missing, consult your local Lull distributor or
the JLG Service Department at (877) 554-5438 or
(717) 485-6657.
