Chapter 14 Maintenance and Inspection 14-5 Regular Checks 14-5-2 Maintenance Timings Use the following table as a timing guide for checking and replacing components of the unit. These intervals are not guaranteed lifetimes; the timing for replacing components depends on the particular conditions of use. In particular, depending on the degree of dirt contamination and abrasion, pinch rollers and cleaners may require replacement earlier than suggested by this table. Note that an arrow in the table means that the component to be replaced is part of the assembly the arrow points to, which must be replaced as a whole. For information on severe conditions (frequent threading/ unthreading) or how to replace components, refer to the Maintenance Manual Volume 1.
