GENERAL PROCEDURE

Power

clean

the

printer

with

the

covers

removed.

Clean

the

feed

rolls,

platen,

and

deflector.

Unless

otherwise

stated,

all

parts

the

printer

should be

inspected

and

lubricated

once

every

three

months.

NOTE:

Lubrication

must be

applied

judiciously

iminate

excessive

quantities

and

prevent

migration

spin-off

into

electrical

con-

tacts.

LUBRICATION

Figures 1 through 7 show

the

points

that

require

lubrication.

The number

references

require

IBM

#10. The

letter

references

require

IBM

#23. Points

that

not

require

lubrication

every

three

months

are

identified

with

the

required

frequency

the

ref-

erence

list.

A rule

thumb should be "All

bearing

areas

having

sliding

motion

use

IBM

#23

and

all

bearing

areas

having

rotational

motion use

IBM

#10 unless

other-

wise

specified".

Machines

with

power

hours

daily

require

frequent

lubrication

than

ma-

chines

used for

single-shift

operation.

The following

areas

are

primarily

affected

idling

time,

since

only

the

operational

shaft

driven:

Motor

and

motor

pulley

Cycle-clutch

spring

and

arbor

Driven-pulley

hub

and

bearing

Operational

cam

bearings

Right-hand

operational

shaft

and

shift cam

bearing

Shift-clutch

spring

and

arbor.

Since

these

machines

are

hot

hours

daily,

some

lubricant

evaporation

can

ex-

pected

areas

not

driven

during

idling,

however,

they

are

not

nearly

affected

items 1 through

Where

power

hoursdaily,

we recommend

lubricating

these

items

every

six

weeks·.
