The load must be secured so as to prevent it from falling or slipping.
Persons guiding the load or securing it must stay in visual contact with the machine
operator.
The machine operator must guide the load the nearest possible to the ground and
avoid any oscillating or swinging movements.
The earth moving machine may be driven with a raised load only if the path of the
machine is as level as possible.
When using earth moving machinery for lifting gear applications, the persons
attaching or securing loads may approach the boom from the side only, and only
after the machine operator has given his permission. The machine operator may
give his permission only after the machine is at a standstill and the work attachment
no longer moves.
Do not use any lifting gear (ropes, chains) which is damaged or not of sufficient
size. Always wear protective gloves when working with lifting gear.
The earth moving machine may be assembled, modified or disassembled only in
accordance with the Operator's Manual of the manufacturer and only under the
supervision of suitable personnel appointed by the contractor.
For example, work on the
• Brake
• Steering
• Hydraulic and
• Electrical systems
of the earth moving machine may be performed only by specially trained personnel.
Stability must be ensured at all times during maintenance.
Secure the work equipment against movement by lowering it to the ground or by
taking appropriate measures, for example supporting brackets or sleeves. If neces-
sary, secure the upper carriage of the excavator against rotation.
When performing maintenance and repair work on an earth moving machine with an
articulated joint, secure the joint with a positive lock when working in the area of the
articulated joint.
When installing or removing counterweights, hitch them only at the points provided
for by the manufacturer.
When jacking up the earth moving machine, place the lifting device in a position
that will avoid slipping. Installing or placing the lifting device in inclined positions is
not permissible.
Secure the raised earth moving machine by supporting it with, for example, support-
ing frames or trestles, or with boards or square beams stacked crosswise.
Safely prop the earth moving machine immediately after it has been raised with the work
equipment. Working under a raised earth moving machine that is held only by the hydrau-
lics is not permissible.
