GENERAL
INFORMATION
Lubrication is an essential part of pre-
ventive maintenance,
affecting to a
great extent the useful life of the unit.
Different lubricants are needed and
some components
in the unit require
more frequent lubrication
than oth-
ers. Therefore, it is important that the
instructions regarding types of lubri-
cants
and the frequency
of their
application be explicitly followed. Pe-
riodic lubrication of the moving parts
reduces to a minimum the possibility
of mechanical failures.
The
Preventive
Maintenance
Schedule
on page 4.18 shows
those items requiring regular ser-
vice and the interval in which they
should
be performed.
A regular
service program should be devel-
oped
to include
all items
and
fluids.
These intervals are based
on average operating conditions.
In the event of extremely
severe
(hot, cold, dusty or wet) operating
conditions, more frequent lubrica-.
tion than specified may be neces-
sary.
Details concerning
lubrica-
tion of the running gear are in Sec-
tion 4 - Maintenance.
All filters and filter elements for air
and compressor
lubricant must be
obtained through Ingersoll-Rand
to
assure the proper size and filtration
for the compressor.
COMPRESSOR
OIL CHANGE
These units are normally furnished with
an initial supply of oil sufficientto
allow
operation of the unit for approximately
6 months or 1000 hours, whichever-
comes first.
If
a unit has been com-
pletely drained of all oil, it must be re-
filled with new oil before it is placed in
operation.
Refer to speciticatlons
in
table on page 5.0.
NOTICE
Some
all
types
are
Incompatible
when mixed and result In the forma-
tion of varnishes,
shellacs,
or lac-
quers which may be Insoluble.
Such
deposits
can cause serious
troubles
Including
clogging
of the
filters.
Where posstble,
do NOT mix oils of
different
types and avoid mixing dif-
ferent
brands.
A
type
or
brand
change Is best made at the time of a
complete
oil drain and refill.
If the unit has been operated
for the
time! hours mentioned above,
it
should
be completely drained of oil. If the unit
has been operated under adverse con-
ditions, or after long periods in storage,
an earlier change period may be nec-
essary as oil deteriorates
with time as
well as
by
operating conditions.
