Never operate an excavator without safety guar s installe . Safety glass an wire mesh cab guar ing must be
installe to protect the operator from flying ebris that may be create uring processing.
Falling object protection structures or fops are require for any application where material is to be han le
overhea . Avoi han ling material overhea whenever possible.
Keep all parts of the machine at least 16 m (50 ft) away from power lines.
All local, state/provincial an fe eral regulations must be met before approaching power lines, overhea or
un ergroun cables, or power sources with any part of the excavator.
Do not operate the machine near energize power lines.
Always contact the electrical company when operating near power lines, power lines shoul be move ,
insulate , isconnecte or e-energize an groun e before operating in the area.
Equipment operation an maintenance practices irectly affect you safety an the safety of those aroun you.
Always use common sense while operating an be alert to unsafe con itions.
Do not operate if there are unsafe con itions. Stop operation imme iately, shut own the machine an report
the unsafe con itions to the proper authority.
Excavators in overhea emolition or high reach applications must have prioritize oil flow to their main
valves.
Machines require high volumes of oil at lower pressures to open an close the jaw in the non-cutting mo e.
In the event of a buil ing or structure collapse, if the excavator ies not have prioritize flow, opening the jaw
will ren er all other functions such as boom an 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
shoul be a resse with your excavator ealer prior to machine installation.
The machines are size for excavator stability when properly operate . However, improper operation, faulty
maintenance or unauthorize mo ifications may cause instability. Know the working ranges an capacities of
the excavator to avoi tipping. Always use the recommen e counterweight.
