SECTION 1 – MAINTENANCE PROCEDURE
GENERAL

• This section ofthe manual describes those aspects of preventive maintenance such as scheduled reports and safety precautions as they pertain to the 45-R drill.
• MAINTENANCE SCHEDULES AND REPORTS
• Ideally, all maintenance should be approached from the preventive standpoint and on a regularly scheduled basis. Obviously, this approach keeps downtime to a minimum and results in reduced maintenance costs. To establish a preventive upkeep program, scheduled inspections and an operator’s daily report are the most useful tools available.
• Schedule inspections should be conducted by the Mine Mechanical and Electrical Maintenance Departments since they are the most qualified. Either department should generate a certain amount of paper work such as inspection records that become a part of the mine’s permanent file on the machine. The inspection records should be explicit, complete, and cover every part of the machine.
• Each machine operator should complete a daily record ofthe machine’s performance. This record should include time worked, time down, reasons for all delays, and observations on any unusual conditions encountered during operation. From these records, items that can potentially cause machine downtime can be corrected or prevented immediately, or scheduled for a future date when the machine availability can be coordinated with the other mine activities. Each problem should be thoroughly reviewed and evaluated before scheduling any maintenance or repair. The following points should be considered during the evaluation.
