FOREWORD

• The purpose of this manual is to provide information concerning the general maintenance of the 49-RII Diesel/Electric Rotary Blast Hole Drill. The Model 49-RII consists of three major units, the lower works, the mainframe and the mast. The lower works provides a foundation for the mainframe and contains the necessary equipment to propel the drill.
• The mainframe includes the hydraulic system, main air system, the diesel/electric drive, and the machinery house. The machinery house encloses the majority of the mechanical equipment necessary for the main air system, 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, includes the operator’s station, and encloses the majority of the controls necessary to operate the drill.
• The mast contains the drill pipe and drilling tools, the pipe racks, and the rotary and pulldown machinery. This manual consists of six chapters, each divided into sections. A table of contents is located in the front of the manual.
