Change Of Work Attachments, Maintenance, Repair - Terex TL80 Operating Instructions Manual

2 Safety and Accident Prevention
2.16 Change of
maintenance, repair
Earth-moving machines shall only be converted,
maintained or serviced under the guidance of a
suitable person designated by the plant operator
and following the
Instructions.
After every change of work attachments, the driver
must convince himself that the quick-attach system
is correctly fastened and locked.
Work on e.g.
• brake systems,
• steering systems,
• hydraulic and
• electric systems
of the machine is only to be carried out by expert
personnel specially trained in these areas.
Stability must be ensured during all type of work on
the machine at all times.
The work equipment must be secured against
movement by lowering it to the ground or
equivalent measures, e.g.
trestles. With the engine running, the unprotected
articulation range of articulated loaders shall not be
entered.
When jacking up earth-moving machines, jacking
devices must be positioned so that they cannot
slip. Jacks must be positioned and applied
absolutely straight, without tilting.
Raised earth-moving machines must be supported
by suitable structures such as crosswise stacks of
planks, square timbers or steel trusses.
Stabilize the earth-moving machine that has been
lifted with the work attachment, immediately after
lifting with a supporting structure. Work under
raised machines which are only supported by their
hydraulics is forbidden.

The engine/motor(s) must be turned off prior to all
maintenance and repair work. These requirements
may only be ignored in the case of maintenance or
repair work which cannot be performed without the
engine/motor(s) running.
When performing maintenance and repair work on
the hydraulic system, the hydraulic system must be
relieved of pressure. With the engine turned off,
lower the work equipment to the ground and
actuate all hydraulic control levers until there is no
pressure in the hydraulic system.
Before working on the electrics or when performing
arc-welding on the machine, the connection to the
battery must be disconnected.
When disconnecting the battery, first the negative
pole then the positive pole must be disconnected.
The battery must be re-connected in reverse order.
During repair work around the battery, it must be
covered with insulating material. Tools should
never be placed on or near the battery.
Protective devices of moving machine parts are
only to be opened or removed after the drive has
been switched off and cannot be switched on
again by unauthorized persons. Protective devices
are e.g. engine/motor covers, doors, protective
grating, trim.
Upon completion of assembly, maintenance or
repair work, all protective devices must once more
be attached in the proper manner.
Load-bearing parts of earth-moving machines are
only to be welded following consultation with the
manufacturer and in accordance with recognized
welding principles.
Protective structures (ROPS; FOPS) are not to be
welded or drilled in any way.
