	'''VARIABLE SPEED DIAL:''' Variable Speed Dial "B", visibly indicates, in windows, the speed range that the machine is operating in, 60 to 500 low range, 500 to 4200 high range.		'''VARIABLE SPEED DIAL:''' Variable Speed Dial "B", visibly indicates, in windows, the speed range that the machine is operating in, 60 to 500 low range, 500 to 4200 high range.

			'''SPINDLE BRAKE:''' Spindle Brake “C”, can be moved in either direction to stop spindle; however, when locking spindle, brake lever should be moved either by pulling towards the operator or pushing away from the operator, then raised. When brake is worn out it has to be replaced. There are no adjustments to be made.

			'''QUILL FEED SELECTOR:''' The Quill Feed Selector “D”, is used for selecting the three feeds: .0015”, .003” and .006” per revolution. It is shifted by pulling knob out and turning from one position to the other. Feeds are stamped on cover below indentation hole. Feed is more readily engaged when spindle is running.

			'''QUILL STOP KNOB:''' Quill Stop Knob “E”, is used to disengage automatic feed in either direction as well as the stop point setting working depths.

			'''MICROMETER NUT:''' Micrometer Nut “F”, is used for setting depths. Each graduation on nut indicates .001” of depth, it reads directly to scale mounted along the side of it. Depths may be obtained by setting micrometer nut in conjunction with quill stop.

			'''FEED REVERSE KNOB:''' The position of the Feed Reverse Knob “G”, depends upon direction of spindle rotation. If boring with right hand cutting tools, pull feed handle towards operator until clutch becomes engaged. Neutral position is between forward and reverse position. It is recommended that the handle be left in neutral position when not in use.

			'''MANUAL FEED HANDWHEEL:''' Feed Reverse Knob “G” should be in neutral position and Feed Control Lever “I”, engaged. Clockwise rotation of Manual Feed Handwheel “H”, moves quill down. The manual feed handwheel and the quill feed handle may be disengaged by moving them outward about .125”.

			'''FEED CONTROL LEVER:''' Feed Control Lever “I”, engages overload clutch on pinion shaft when positioned left and will stay engaged until either quill stop comes in contact with micrometer adjusting nut, forcing feed control lever to drop out automatically, or release manually by engaging lever to right. FEED CONTROL

			'''OVERLOAD CLUTCH:''' The Feed Control Overload Clutch is set at the factory to hold up to 200 lbs of down pressure on quill, which will accommodate drills up to .375” diameter in mild tool steel.
			* NOTE - The feed control lever must be engaged in order to use manual feed controls. the quill feed handle and manual feed handwheel may be removed when not in use.

			'''QUILL:''' Quill “J”contains the spindle assembly and can be raised or lowered by using the quill feed handle “M”.

			'''SPINDLE:''' Spindle “K”, performs the actual rotation and also retains the machine tooling.

			'''QUILL LOCK:''' Quill Lock “L”, is a friction lock for use when quill is in a stationary position such as a milling operation. It is recommended that this lock be used whenever quill movement is not desired.

			'''QUILL FEED HANDLE:''' Quill Feed Handle “M”, is used to raise and lower the quill manually. It is generally recommended that handle be engaged when using the power feed. It may be removed by simply pulling handle off.

			'''POWER FEED TRANSMISSION ENGAGEMENT CRANK:''' Power Feed Transmission Engagement Crank “N”, engages power feed worm gear. When lever is in right hand hole, the power feed worm gear is engaged. To engage worm gear, pull knob out and crank handle in clockwise or down direction and move to opposite position.

			* NOTE - Crank should be rotated counter-clockwise to engage power quill feed. Crank should be rotated clockwise to disengage.

			'''HI-NEUTRAL-LO LEVER:''' The Hi-Neutral-Lo Lever “O”, is used to put the attachment into either back gear or direct drive. Rotate the spindle by hand to facilitate meshing of clutch or gears. Neutral is provided to permit free spindle rotation for indicating and setup work. In the high-speed position (direct drive) the spindle is driven by tapered clutch teeth. If the clutch is not meshed tightly, clutch rattle will be heard. This can be corrected by loosening the two securing screws in lever while in high-speed position. The clutch spring will automatically adjust the clutch. Tighten the two securing crews in lever.

			'''SPEED CHANGE HANDWHEEL:''' DO NOT attempt to change spindle RPM unless the motor is running. Dial speeds will only be approximate. Belt wear will cause a slight variation in speeds from what is indicated on the dial. Spindle speeds are adjusted by turning Speed Change Handwheel “P”, on the front of the belt housing. There are two ranges: 60 to 500 and 500 to 4200.
			* To obtain 60 to 500 (low range):
			1. Hold the Hi-Neutral-Lo lever (right rear side of the attachment) so the gears are clear of one another.
			2. rotate the spindle nose by hand until the gears line up, then move the Hi-Neutral-Lo lever to the “Lo” position (back gear).
			3. Use the low range on the drum switch to engage the back gears.

			CAUTION - If the back gears do not mesh, do not force the lever.

			* To obtain 500 to 4200 (high range):
			1. Hold the Hi-Neutral-Lo lever (right rear side of the attachment) so the gears are clear of one another.
			2. rotate the spindle nose by hand until the gears line up, then move the Hi-Neutral-Lo lever to the “Hi” position.
			3. Set the drum switch to high range.

			'''MOTOR:''' Motor “Q”, has the following specifications:
			* 2 HP variable speed (with 2J head)
			* 3 HP 30 minute duty rate

			'''DRAWBAR:''' When tightening or loosening the Drawbar “R”, it is necessary to lock the spindle. To accomplish this, use the spindle brake which is located on the left side of the belt housing, pulling towards the operator or pushing away from the operator until it binds, then raise the quill feed handle. Drawbar has 7/16”-20 right hand thread and should be tightened by hand with normal amount of pressure using wrench furnished with machine. To loosen collet, back off drawbar and if collet does not open immediately, give knob on top of drawbar a slight tap. Spindle has non-sticking taper and collet should release readily.
