FOREWORD:
- The purpose of this manual is to provide information concerning the electrical maintenance ofthe 60/ 61-F
rotary blast hole drill. - The 60/61-R consists ofthree major units, the lower works, the mainframe and the mast. The lower work~
provides a foundation for the mainframe and contains a portion of the equipment necessary to propel tht
drill. The mainframe includes the hydraulic, main air and auxiliary air systems, the hoist-propel trans
mission and the machinery house. The machinery house encloses the majority of the mechanical equipment
necessary for the main and auxiliary air systems, the hydraulic systems and electrical control
systems. The machinery house is pressurized with filtered air to minimize dirt and heat build-up. ThE
operator’s cab, mounted to the mainframe, provides the operator’s station, and encloses the majority of thE
controls necessary to operate the drill. - This manual consists of three chapters, each divided into sections. A table of contents is located in the
front of the manual. - Throughout this manual the words CAUTION, WARNING and NOTE appear in bold face type.
CAUTION is preceded by the safety alert symbol A and indicates that injury to personnel could
occur if the proper procedures are not followed during operation or maintenance. Always read the
CAUTION note carefully and use extreme care while performing that particular function. - WARNING indicates a possible hazard to the machine or its components ifthe proper procedures are not
followed. Whenever the word WARNING appears, special attention should be given to prevent possible
equipment damage. - NOTE is used to stress a point or to give additional information concerning the procedure being discussed.
- These CAUTION’s and WARNING’s are not all-inclusive. It is impossible for Bucyrus-Erie Company to
know, evaluate, and advise maintenance and service personnel in every conceivable way a service
operation might be performed and of the resulting possible hazardous consequences of each method. It is
therefore extremely important that anyone who uses a service procedure or tool which is not recommended
by Bucyrus-Erie Company to first satisfy himself that the service procedure or tool he chooses will not
jeopardize his own safety, the safety of others, or cause machine or component damage. - Every effort has been made to make this manual as complete and accurate as possible at the time of
publication. Bucyrus-Erie Company, however, reserves the right to continually improve its products. For
this reason changes may have been made to the machine or its equipment that are not detailed in this
manual.
