3. Thread the spindle nut (E) Fig. 14 on the spindle. Place one wrench on the flats at the top of the spindle and one wrench on spindle nut (E) and tighten. 4. IMPORTANT: Always place the “keyed” washer (D) Fig. 13, on the spindle before screwing on the spindle nut (E) Fig. 14. The “keyed” washer (D) Fig.19 prevents the spindle nut (E) Fig. 14 from loosening when the spindle turns counterclockwise.

Install three 1/4-20 x 1/2" hex head screws with lockwashers through the rear of the tool (A) Fig. 15, and into the tapped holes (B) on the back of the electrical box. OPERATING CONTROLS AND ADJUSTMENTS A B Fig. 15 STARTING AND STOPPING THE SHAPER To apply power to the machine, push “ON” button (A) Fig.16. To stop the machine, push “OFF” button (B). LOCKING SWITCH IN THE “OFF” POSITION IMPORTANT: When the machine is not in use, the switch should be locked in the “OFF” position using a padlock (A) Fig. 17, (Delta Cat. No. 50-325), with a 3/16" diameter shackle to prevent unauthorized use.

To raise the spindle height, turn the handwheel (B) clockwise. To lower the spindle height, turn the handle (B) counterclockwise. The scale (C) Fig. 18 indicates the spindle travel range from 0" to 3" and is marked in 1/16" increments. Minor cutter height adjustments can be measured using the pointer (D) along the scale (C). Tighten the lock knob (A) after adjusting the spindle height. CHANGING SPEEDS AND ADJUSTING BELT TENSION The machine is supplied with a 2-step motor pulley and a 2-step spindle pulley that provide spindle speeds of 7,000 and 10,000 RPM. With the belt on the largest step of the motor pulley and the smallest step of the spindle pulley, the spindle speed will be 10,000 RPM. With the belt on the smallest step of the motor pulley and the largest step of the spindle pulley, the spindle speed will be 7,000 RPM.A chart (Y) Fig. 19 that illustrates the correct belt placement for 7,000 or 10,000 RPM is located on the inside panel of the motor access door. To change speeds and adjust belt tension: DISCONNECT MACHINE FROM POWER SOURCE. 1. Open motor access door (Z) Fig. 19. 2. Loosen the thumb screw (A) Fig. 20. Release tension on the belt by moving the lever (B) to the left. Position the belt (C) on the desired steps of the spindle pulley (D) and the motor pulley (E), and apply belt tension by moving the lever (B) to the right. When the desired belt tension is attained, tighten the thumb screw (A). 3. Proper belt tension is approximately a 3/32" deflection when using light finger pressure on the belt between pulleys. IMPORTANT: Pulleys (D) and (E) Fig. 20 should always be aligned with each other to provide maximum belt performance and reduce belt wear. To check pulley alignment, refer to section “REPLACING SPINDLE CARTRIDGE”. 8 REVERSING SPINDLE ROTATION DISCONNECT MACHINE FROM POWER SOURCE. The motor is equipped with a reversing switch (X) Fig. 19, located on the motor junction box. Never attempt to reverse the rotation of the spindle with the motor running. OPERATIONS The following examples show set-up and operational procedures when using the fence, collars, and starting pin. Please review this information carefully before turning on the power to avoid personal injury and/or damage to the machine. SHAPING WHEN USING THE FENCE AS A GUIDE Using the fence is the safest and most satisfactory method of shaping. Most straight work can be shaped using the fence described below. 1. For average work, where a portion of the original edge of the work is not touched by the cutter, both the front and rear fences are in a straight line (Fig. 21). 2. When the shaping operation removes the entire edge of the work (jointing or making a full bead), the shaped edge will not be supported by the rear fence when both fences are in line (Fig. 22). In this case, advance the work to the position shown in Fig. 22 and stop. 3. Advance the rear fence to contact the work (Fig. 23), putting it in line with the cutting circle. Fig. 21 Fig. 22 Fig. 23 SHAPING WITH COLLARS AND STARTING PIN When shaping with collars and starting pin, follow the rules below for superior finishing and safety in operation. 1. Free the collars of ALL gum or other substances, and confirm that they are smooth. 2. Confirm that the edge of the work is smooth. ANY irregularity in the surface that rides against the collar will be duplicated on the molded surface. 3. A portion of the edge of the work MUST remain untouched by the cutters in order for the collar to have sufficient bearing surface. The right method is shown in Fig. 24, while Fig. 25 illustrates the wrong method. 4. The work MUST be...
