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:
A4/£ 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.

For slower speeds use a Multi-Speed Attachment available from your nearest Sears retail store or mail 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.
