FOREWORD
The purpose of this manual is to provide information concerning the general maintenance ofthe 661 67-R rotary blast hole drill.
The 65/67- R consists of three major units, the lower works, the mainframe and the mast. The lower works provides a foundation for the mainframe and contains a portion ofthe equipment necessary to propel the drill. The mainframe includes the hydraulic, main air and auxiliary air systems, the hoist-propel transmission 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 six 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.
W ARNIN G 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. Itis 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, a Division of Becor Western Inc., 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.
