SECTION 5   MAINTENANCE

This section lists the maintenance procedures that need to be performed. 

See the 

Maintenance Log

 located after this section for a complete list of maintenance

procedures and intervals. Keep track of machine maintenance by filling in the machine
hours and the date you perform each procedure. 

This symbol

 identifies the interval (hours of operation) at which each maintenance pro-

cedure should be performed.

Be sure to refer to option and engine manuals for other maintenance procedures.

Wear Life

See Table 5-1.   

This chart lists estimated life expectancy of common replacement parts if

proper maintenance and operation procedures are followed. Due to the many variables
which exist during sawmill operation, actual part life may vary significantly. This informa-
tion is provided so that you may plan ahead in ordering replacement parts.
