A good

solid

founda-

tion

is

a "

must"

for

a

pre

ision

machine

tool.

Pr

e

ferabl

y,

it

should

be

of

heavy

c

oncrete.

If

this is

not

possible,

it

is

essential

that

the

floor

be

rigidl

y

supported

.

The

ne

xt

step

is

leveling,

and

too

much

stress

can

not be

la

id on

the

importance

of

doing

this

w

ith

the

utmost

care.

Use

LUBRICATION

More

OPERATION

To

benefit

fully

from

the

ease

which

has

been

built

into

the

Monarch

61

and

to

avoid

damage

,

the

operator

should

familiarize

himself

completely

with

the

functions

of

the

to

the

headstock

by

always

speed

.

Levers
