APPLICATION VALIDITY OF SAFETY REGULATIONS
Never operate an excavator without safety guards installed. Safety glass and wire mesh cab guarding must be
installed to protect the operator from flying debris that may be created during processing.
Falling object protection structures or fops are required for any application where material is to be handled
overhead. Avoid handling material overhead whenever possible.
Keep all parts of the machine at least 16 m (50 ft) away from power lines.
All local, state/provincial and federal regulations must be met before approaching power lines, overhead or
underground cables, or power sources with any part of the excavator.
Do not operate the machine near energized power lines.
Always contact the electrical company when operating near power lines, power lines should be moved,
insulated, disconnected or de-energized and grounded before operating in the area.
Equipment operation and maintenance practices directly affect you safety and the safety of those around you.
Always use common sense while operating and be alert to unsafe conditions.
Do not operate if there are unsafe conditions. Stop operation immediately, shut down the machine and report
the unsafe conditions to the proper authority.
Excavators in overhead demolition or high reach applications must have prioritized oil flow to their main
valves.
Machines require high volumes of oil at lower pressures to open and close the jaw in the non-cutting mode.
In the event of a building or structure collapse, if the excavator dies not have prioritized flow, opening the jaw
will render all other functions such as boom and tracking slow or inoperable because the oil will take the path
of least resistance, which is the shear function. Although this is not a common situation, it is something that
should be addressed with your excavator dealer prior to machine installation.
The machines are sized for excavator stability when properly operated. However, improper operation, faulty
maintenance or unauthorized modifications may cause instability. Know the working ranges and capacities of
the excavator to avoid tipping. Always use the recommended counterweight.
The following conditions affect stability:
