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
