2.3 LUBRICATION
Lubrication plays an important role in maintaining the
printer at its initial performance level throughout a
long product life as well as preventing potential
troubles. Make sure to apply the specified lubricant in
the appropriate amounts at the specified intervals.
2.3.1 LUBRICANT TYPES
The type of lubricant used greatly influences the
printer's performance and durability, and special
attention is required tob its low-temperature
characteristic. Consequently, the lubricants to be
used with the printer are specified by us on the basis
of the results of the thorough analyses of technical
data for many types of lubricants and verious
experiments.
Note that our specified lubricants are available in 40-
cc (40-gm) plastic containers (which is the minimum
supply unit).
The two types of lubricants to be used with this printer
are : G-15 and G-18.
2.3.2 LUBRICATION REQUIREMENTS
Before applying lubricant during an assembly or
disassembly procedure, be sure to first thoroughly
cleaned the part to be lubricated. For the lubricating
points and type of lubricant types, see section 2.3.3,
“Lubrication Points” , “ Lubrication Points of
Model-405R” . (The numbers are used to identify
lubrication points correspond to those in the table and
the figure)
For the lubrication timing, apply periodic lubrications
according to the following classification. If lubrication
is removed due to cleaning, or after disassembly or
parts replacement, be sure to perform lubricate the
required parts regardless of the actual lubrication
interval.
A. To lubricated after every six months.
B. To lubricated after overhauling or 1,000,000 after
having printed lines
