During the break in period, a new pin and bushing connection has to be lubricated every eight (8) hours for the first one hundred (100) hours of operation for a standard machine working in an average duty cycle; all other machines should be lubricated every four (4) hours for the first twenty (20) hours and every eight (8) hours for the next eighty (80) hours of operation. Refer to page 4-22 for more details in regards to the guidelines for reduced lubrication intervals. O - Break in (After first 50 Hrs) Inspection & Maintenance Required. X - Regular Inspection & Maintenance Required.
