TW85 13
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.
Alterations, such as welding of the hydraulic
system, are only to be undertaken with the
manufacturer’s permission.
Before commencing work on the hydraulic system,
the operating pressure, pilot pressure, back
pressure and pressure inside the tank must be let
off.
Swallowing lubricants, or long and repeated skin
contact, can be hazardous to health. When used
properly, there is no particular danger to health.
The safety specification sheets from the mineral
companies must be observed.
Only the hoses specified by the manufacturer shall
be used.
Hydraulic hoses must be routed and assembled by
expert personnel.
In the vicinity of fuel or batteries, smoking and
naked flames are prohibited.
2.18 Recovery, loading, transportation
Earth-moving machines are only to be loaded onto
recovery vehicles if adequate towing vehicles are
used.
The tow fixing points specified by the manufacturer
must be employed.
For loading and transportation, earth-moving
machines and all necessary auxiliary equipment
must be secured against unwanted movement.
The traveling gear and crawler unit of earth-moving
machines must be sufficiently cleaned of mud,
snow and ice to ensure that ramps can be driven
up without risk of slipping.
When transporting the earth-moving machine on
trucks, flatbed trailers, or by rail, it must be
sufficiently secured with chocks and by attachment
to the lashing points.
Before setting off, the route to be taken must be
examined to determine whether the roads are wide
enough, entrances and passages under bridges
are large enough and that roads and bridges have
sufficient carrying capacity.
