Foreword
This manual is written for an experienced technician.
Essential tools required in performing certain service
work are identified in this manual and are
recommended for use.
Live with safety: Read the safety messages in the
introduction of this manual and the cautions presented
throughout the text of the manual.
This is the safety-alert symbol. When you see this
symbol on the machine or in this manual, be alert to
the potential for personal injury.
Technical manuals are divided in two parts: repair and
operation and tests. Repair sections tell how to repair
the components. Operation and tests sections help you
identify the majority of routine failures quickly.
Information is organized in groups for the various
components requiring service instruction. At the
beginning of each group are summary listings of all
applicable essential tools, service equipment and tools,
other materials needed to do the job, service parts kits,
specifications, wear tolerances, and torque values.
Technical Manuals are concise guides for specific
machines. They are on-the-job guides containing only
the vital information needed for diagnosis, analysis,
testing, and repair.
Fundamental service information is available from
other sources covering basic theory of operation,
fundamentals of troubleshooting, general maintenance,
and basic type of failures and their causes.

Avoid Work Site Hazards
T147554 –UN–01NOV01T147555 –UN–13DEC01
Avoid contact with gas lines, buried cables and water
lines. Call utility line location services to identify all
underground utilities before you dig.
Prepare work site properly. Avoid operating near
structures or objects that could fall onto the machine.
Clear away debris that could move unexpectedly if run
over.
Avoid boom or attachment contact with overhead
obstacles or overhead electrical lines. Never move any
part of machine or load closer than 3 m (10 ft) plus twice
the line insulator length to overhead wires.
Keep bystanders clear at all times. Use barricades or a
signal person to keep vehicles and pedestrians away. Use
a signal person if moving machine in congested areas or
where visibility is restricted. Always keep signal person in
view. Coordinate hand signals before starting machine.
Operate only on solid footing with strength sufficient to
support machine. Be especially alert working near
embankments or excavations.
Avoid working under over-hanging embankments or
stockpiles that could collapse on machine.
TX03768,0000BAF –19–21NOV01–1/1
Keep Riders Off Machine
T148715 –UN–06DEC01
Only allow the operator on the machine. Keep riders off.
Riders on machine are subject to injury such as being
struck by foreign objects and being thrown off of the
machine. Riders also obstruct the operator’s view resulting
in the machine being operated in an unsafe manner.

T145317 –UN–06SEP01
Before moving machine, be sure all persons are clear
of the machine travel path. Turn around and look
directly for best visibility. Use mirror to assist in checking
behind the machine. Keep windows and mirror clean and
in good repair.
Be certain backup warning alarm is working properly.
Use a signal person when backing if view is
obstructed or when in close quarters. Keep signal
person in view at all times. Use prearranged hand signals
to communicate.
TX03768,0000BA3 –19–26OCT01–1/1
Avoid Machine Tipover
T147495 –19–26OCT01
Use seat belt at all times.
Do not jump if the machine tips. You will be unlikely to
jump clear and the machine may crush you.
Load and unload from trucks or trailers carefully. Be
sure truck is wide enough and secured on a firm level
surface. Use loading ramps and attach them properly to
truck bed.
Be careful on slopes. Use extra care on soft, rocky or
frozen ground because machine may slip sideways in
these conditions.
Ensure solid footing. Use extra care when operating on
stockpile materials, or near banks or excavations that may
cave-in and cause machine to tip or fall.

Add And Operate Attachments Safely
Always verify compatibility of attachments by contacting
your authorized dealer. Adding unapproved attachments
may affect machine stability or reliability, and may create
a hazard for others near the machine.
Ensure that a qualified person is involved in attachment
installation. Add guards to machine if operator protection
is required or recommended. Verify that all connections
are secure and attachment responds properly to controls.
Carefully read attachment manual and follow all
instructions and warnings. In an area free of bystanders
and obstructions, carefully operate attachment to learn its
characteristics and range of motion.
TX03768,0000B70 –19–21DEC01–1/1
Use Special Care When Operating
T148749 –UN–05DEC01T147438 –UN–26OCT01
Never use the loader to lift people. Do not allow anyone
to ride in the bucket or use the bucket as a work platform.
Operate carefully with raised loads. Raising the load
reduces machine stability, especially on side slopes on
soft terrain. Drive and turn slowly with a raised load.
Ensure that objects in the bucket are secure. Do not
attempt to lift or carry objects that are too big or too long
to fit inside the bucket unless secured with an adequate
chain or other device. Keep bystanders away from raised
loads.
Be careful when lifting objects. Never attempt to lift
objects too heavy for your machine. Assure machine
stability and hydraulic capability with a test lift before
attempting other maneuvers. Use an adequate chain or
sling and proper rigging techniques to attach and stabilize
loads.
Never lift an object above or near another person.
