Foreword
Index
In orcler that this milling -`chine may give con-
tinuous, satisfactory service, it ls necessary that it be
properly installed, opcratcd and maintained. This
manual is printed with this in view. It should be
placc.d in the hands of the proper supervisor in the
plant and the information it contains should be
studied carefully.
This milling machine was designed and manufac-
tured to conform to Ex-Cell-O's high standard of
machine tool pcrformancc.. It was built to rigid speci-
fications by trained workmen, under competent
supervision. It was inspcctcd at various stages of
construction. and has been tested in actual operation.
Some details of the. machine furnished may differ
from the description in this book. The reason for
such difference is constant improvement in design)
equipment and matcrjals, as well as changes neces-
sary to fill individual orders.

preparing Machine for Installation:
when machine ls uncrated, check all parts and
acccssorles a_-nst the packlng list to make sure
nothing is missing.
The following items arc shipped With the maChlne.
shipping list, instructions, operation and mainten-
ance bulletin. electrical scrvicc. information.
After the machine ls uncratC,d. it nluSt be inSPCCtCd
to ascertain thi\t no part has been damaged or dis-
arranged during shipment. All the paper wrappings
that have bcc.n used to prc\,ent dust and dirt from
gettmg into the machine should be removed The
wooden skids must bc. left ()n the machine until it is
placed in position.
The machinc. should bc placed in the deSirl.d loca-
tion with sufflclent room between surrounding ma-
chines to allow efficient operation. When a crane is
used to lift the machine mto position. the lifting
sling should be placed around the front of the ram.

caution must bc exercised especially during the
instalkttion of the machine. No force should be
exerted on the spindle since the closely fitted pre-
cision ball bearing races COuld be damaged.
Install Table Dials and Handwheels:
on some models, table dials and handwheels are
sl"ppcd m the rear compartment of the mlll. Place
dials on table lead screw. screw handwtlccl on lead
screw until it is _oo5 from dial. Screw jam nut on
lead screw and lock against handWheel. Check dial
anc] handwheel clearance with.()()5 fcelcr. Adjust if
necessary
Foundatiol1:
To get satisfactory PCrfOrmanCe, it iS important
that the "lchin|. has a solid foundation and that it
is lcvcI. A solld concrete floor or foundation gives
the bc.st footim|. but a firm wooden floor, free from
vltmtion -y bc used. when the machine is placed
on an upper floor ()r balcony. it should be as close
as possible to a pillar or colunln.
Leveling:
Four foundation rest pads and bolt hOIC.S arc Pro-
vided at the bottom of the base of the machine.
stc.el wcdees. n|.vcr wooden wedges should be used
under the rest pads for lcvcling. The level should be
pk\ced lengthwisc and crosswise on the table. A
good machinist,s lcvcl should be used. and the bubble
should bc allowed sufficient time to come to rc.st.

Lubrication
EX-CELL-a RAM TuRRET
MILLING MACHINE - STYLE 602
The machine must be lubricated before it lS
started. The use of the proper lubricant at the desig-
mlted places ls necessary to obtaln the best OPerating
pcrformancc and to insure the maxlmum service
llfc of the machine.
Back Gear Housing Oll Level should be checked
periodically zlnd an oil such as #30 S.A.E. is recom-
mended. The housing should be filled to oil level
line on window.
The Oil Cup and Oil Fittings Should bC filled
with a way oll daily.
The grcasc flttingS Should bC greased Weekly.
splndlc Bearings :Ire lubricated and sealed for the
life of the machine.
MOTORS - The manufacturcr`s recommendation
should bc followed.
when the machine is equipped with optional table
power feed, the oil level in the gear box should be
checked periodically and filled until it flows out the
fiIImg hole, with #30 SAE.
on machine equipped with optional one shot
lubrication system. use socony-Mobil Oil Vactra #2
or equivalent.
Discretion in oiling and greasing Should be em-
ployed at all times. Over oillng and greasing may
result in an undesirable escape of these substances
from the mac.hine. If this trouble is experienced Cut
down on amount of lubricant used or increase
period of applicatlon accordingly.
