POWER ON
To
turn
spindle
motor
on
, depress
"start"
button
located under
the
table
(8,
Fig. 10). This also
starts
the
lubrica
ting
system
oil
pump
.
After
½
minute
the
oil
level should rise
to
the
mid-point
of
the sight
glass
in
the
column
cap
of
the machine.
Th
is
shows that
the
machine
is
ready
for
operation
.
The 1
HP
motor
furnished
as
standard
with
this
machine
has
enough power
to
take
as
heavy a
cut
as
you
will
normally
wish, when crossfeeding and
grinding
without
coolant.
If
either plunge grinding
or
grinding
with
coolant,
it
is
relative
ly
easy
to
overload
the
motor
. Make certain
motor
tempera-
ture
does
not
exceed a
55°C
(99°F)
temperature
rise
or
permanent damage may result.
If
you
anti-
cipate heavy grinding
use,
we
recommend installing
spindle
motor
overload protection.
LONGITUDINAL
FEED
Feed the
table
by
operating
the
large handwheel.
If
your
grinder
has
a cable drive
(rather
than a
rack
and
pinion
drive) you can readjust
the
position
of
the
handle
on
the wheel
by
cranking
the table
to
the
end
of
its travel and
continuing
to
turn
the
wheel (slipping
the
cable)
to
the
desired
position
.

a few
times. (Sp
