2.5.2 Lubrication
With no need for periodical lubrication, you have only to lubricate
new parts after replacement. If any oil or grease on contact parts
is soiled, wipe it off and newly lubricate the parts.
Note:
• See the "mechanism assembly" diagram of the "parts
list" for the lubricating or greasing spots, and for the
types of oil or grease to be used.
2.5.3 Suggested servicing schedule for main components
The following table indicates the suggested period for such ser-
vice measures as cleaning, lubrication and replacement. In prac-
tice, the indicated periods will vary widely according to
environmental and usage conditions. However, the indicated
components should be inspected when a set is brought for ser-
vice and the maintenance work performed if necessary. Also
note that rubber parts may deform in time, even if the set is not
used.
