INSTALLATION:
Three 1 3/32 inch diameter holes have been pro-
vided in the base through which bolts or screws may
be inserted to secure the drill press to a well con-
structed bench or tool stand.
To install motor loosen the motor mount lock
screws, Fig. 1, until the motor mount may be re-
moved. Fasten the motor to the motor mount with
the bolts, nuts, and washers provided so that when
motor mount is reinstalled on the tool, the larger
portion of the mount will be down. For convenience,
if your motor has a switch, and rotation will be cor-
rect, place motor on motor mount so that the switch
is on the left side.
Direction of rotation of the
spindle must be clockwise when viewed from pulley
end of spindle.
Mount the motor pulley, No. 60, on motor shaft
so that the small diameter is at bottom. For normal
speeds, the largest groove on the motor pulley should
be in line with the smallest groove on the spindle
pulley, No. 1.
Tighten the pulley set screw with the larger Allen
wrench, No. 62. If your motor shaft has a flat on
it, position the pulley so that the set screw will
tighten against the flat.
Place belt around the pulleys and tighten, not
excessively, by sliding the motor mount away from
tool.
Tighten the motor mount lock screws to
maintain this tension.
Adjust the screw, No. 42, until the center line of
the motor is parallel with the center line of the
column.
MOTOR:
A 4/£ horsepowei^475Q R.P.M^baH bearing mutor
will provide sufficient speed and power for your
drill press on general work. For continuous heavy
duty operation a 1 /2 horsepower motor is recom-
mended.
SPEED:
The spindle speeds obtainable with these 4 step pul-
leys are shown in Fig. 2.

order house. Ask for Catalog No. 9A-2338.
LUBRICATION:
The spindle and pulley bearings have been packed
with lubricant and will require no further attention
for the life of the bearing.
Place a few drops of oil occasionally on the pinion
shaft, No. 54. The oil hole is located in the hub
on trie right hand side of the head.
To maintain smoothness of operation and to pre-
vent rust, occasionally apply a small amount of
light cup grease to the quill while in a down posi-
tion. With quill still fully extended, reach into the
backside of the head and apply grease to the spindle,
below the pulley, and to the upper portion of the
quill.
Occasionally wipe the column, table and base
with an oil soaked rag to prevent rust and maintain
smooth sliding action.
CONTROLS:
The chuck is a key-type and has a capacity of 0-1 /2
inch diameter. It is equipped with a lock collar to
retain it on the spindle. This eliminates the neces-
sity of having collet chucks for such tools that de-
velop side thrust while in operation, such as routers.
The feed stop unit provides a means of presetting
hole depths before drilling or for drilling several
holes to the same depth.
The lock screw, No. 36, when tightened, holds
the feed stop collar, No. 37, in place. The two pieces,
as an assembly, can be moved on the stop rod for
fast positioning by turning the unit a quarter turn
and sliding it up or down to an approximate pr.aifir.ri,
The feed stop adjusting collar, No. 34, can then
be adjusted to the exact depth desired.
CAUTION: The top of the adjusting collar should
never be more than J/s" away from the shoulder of
the feed stop collar after an adjustment has been
made. If the desired adjustment can not be made
within the J/g" allowance, reposition the unit and
adjust the feed stop adjusting collar.
The feed stop rod is a gauge, with 5 inches of
1/16 inch graduations, carrying the feed stop and
lock nut.
The feed handle is used to raise and lower the
chuck 4 inches. It has an automatic spring loaded
return action.
The quill lock handle when tight holds the quill
at any depth of cut for such operations as shaping,
routing, surface grinding, etc. Always release the
quill lock before changing position of quill.
The table lock handle and headstock lock handle
control the barrel locks which grip the column.
When releasing either of these handles do so with
care. Support the part you wish to adjust so that
it will not drop too rapidly causing damage to the
tool.
The feed return adjusting knob controls the spring
tension on the feed lever.
The motor mount has been hinged in order to
make the changing of spindle speeds easier.
The
hinge action incorporated in this motor mount will
allow quicker belt changes. To move the belt from
one pulley groove to another, pivot the motor for-
ward and slip the belt into the desired grooves.
