2.19 Maintenance
•
Do not perform any maintenance work or repair task that you
do not understand thoroughly.
•
Park the machine on firm and level ground in a well lit and well
ventilated area suitable for performing service or maintenance
work.
•
Switch the battery current off at the switch located under the
hood at the rear of the machine and remove the ignition key
before beginning work on a machine. Place a
Do Not Operate
tag across the opening of the cab to alert any operator that
maintenance is in progress.
•
Do not work on or under any machine that is supported only by
a hydraulic jack or hoist. Always use mechanical supports to
ensure that the machine will not fall. Terex jack stands work
well to support the machine while performing maintenance or
repair work.
•
Make sure the work area around the machine is safe and make
yourself aware of any hazardous conditions that may exist. If
the engine needs to be started inside an enclosure, make sure
that the engine’s exhaust is properly vented.
•
Be sure all protective devices including guards and shields are
properly installed and functioning correctly before beginning
any service task. If a guard or shield must be removed to per-
form the maintenance work, use extra caution.
•
Always use the appropriate tools for the work to be performed.
Tools should be in good condition and you should understand
how to use them properly before performing any task.
•
When replacing parts or fasteners, use parts of equivalent
quality, grade and/or size. Use original Terex components to
ensure the proper form, fit, and function of replacement parts.
•
When performing maintenance work, always wear appropriate
safety clothing for the task to be performed. Some examples
might include: safety shoes, safety goggles and safety gloves.
•
Relieve hydraulic system pressure by relaxing all hydraulic
actuators prior to attempting any hydraulic maintenance or
repair.
