Page 3: High-Low Range Switch
HIGH-LOW RANGE SWITCH High-Low Range Switch “A”, Figure 2.2, is a motor reversing switch. When the attachment is in direct drive (HIGH SPEED), the motor and spindle are turning in a clockwise direction as viewed from the top of machine. When the attachment is in “Back Gear”... -
Page 4: Spindle Brake
SPINDLE BRAKE Spindle Brake “C”, Figure 2.4, 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. -
Page 5: Quill Stop Knob
QUILL STOP KNOB Quill Stop Knob “E”, Figure 2.6, is used to disengage automatic feed in either direction as well as the stop point setting working depths. MICROMETER NUT Micrometer Nut “F”, Figure 2.6, is used for setting depths. Each graduation on nut indicates .001” of depth, it reads directly to scale mounted along the side of it. -
Page 6: Feed Control Lever
FEED CONTROL LEVER Feed Control Lever “I”, Figure 2.8, 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. -
Page 7: Quill Feed Handle
QUILL FEED HANDLE Quill Feed Handle “M”, Figure 2.10, 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. TP5294 Figure 2.10 - Quill Feed Handle POWER FEED TRANSMISSION ENGAGEMENT... -
Page 8: Hi-Neutral-Lo Lever
HI-NEUTRAL-LO LEVER The Hi-Neutral-Lo Lever “O”, Figure 2.13, 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. -
Page 9: Speed Change Handwheel
SPEED CHANGE HANDWHEEL - CAUTION - 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”, Figure 2.14, on the front of the belt housing. - Page 10 MOTOR Motor “Q”, Figure 2.15, 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”, Figure 2.15, 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.

OPERATIONAL PROCEDURES Spindle Speed - CAUTION - DO NOT change speed when spin- dle is stationary. Change speed only when spindle is running. To change speed within range: 1. Start spindle. 2. Turn handwheel “A”, Figure 2.16, to select required speed. TP5300 Figure 2.16 - Spindle Speed Change Back Gear (Low Speed) - Page 12 Direct Drive (High Speed) To change range from back gear to direct drive: 1. Switch “B” to OFF (Stop spindle rotation). 2. Move lever “C”, Figure 2.18, through neutral to HIGH. High 3. Rotate spindle by hand until the clutches are felt to engage.
