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.
• Disconnect the battery and remove the ignition key from the ignition 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.
• 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 perform 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.
