To install the R-8 collet: 1. UNPLUG THE MILL/DRILL! 2. Remove the drawbar cap. 3. Carefully clean the surface of the collet and spindle taper. Ensure that it is free of debris, oil and grease of any kind. 4. Insert the cutting tool into the collet. 5. Insert the collet up into the spindle taper. 6. Slide the collet the rest of the way in until it makes contact with the threads at the end of the drawbar. 7. Using your fingers, thread the drawbar into the collet until the collet draws up into the spindle taper. 8. While supporting the tool in the collet with one hand, tighten the drawbar with the 17mm wrench in your opposite hand. Note: Do not overtighten the drawbar. Overtightening makes collet removal difficult and causes damage to the drawbar threads, collet, and the spindle taper. Keep in mind the taper keeps the collet and tool in place. The drawbar simply aids in seating the taper. To remove the collet: 1. UNPLUG THE MILL/DRILL! 2. Tighten the headstock lock. LACERATION HAZARD! Leading edges of end mills and other cutting tools can be very sharp. Protect your hands with gloves or a shop towel when handling. 3. Protect the table surface with a piece of cardboard or hold the cutter or tool with a shop towel to prevent it from falling out of the collet. 4. Using the 17mm wrench, loosen the drawbar but DO NOT remove it. NOTICE DO NOT completely unscrew the drawbar before striking it with the hammer. You will damage the threads on the drawbar and the arbor. 5. Using the brass hammer, tap the drawbar to unseat the taper. 6. Unscrew the rest of the drawbar by hand and remove the collet. Note: When not in use, always remove collets and cutting tools from the spindle taper. Oxidation may cause the collet to seize and make it hard to remove later. -17 G0463 Small Mill/Drill SECTION 4: OPERATIONS Operation Safety Damage to your eyes, lungs, and ears could result from using this machine without proper protective gear. Always wear safety glasses, a respirator, and hearing protection when operating this machine. Loose hair and clothing could get caught in machinery and cause serious personal injury. Keep loose clothing and long hair away from moving machinery. NOTICE If you have never used this type of machine or equipment before, WE STRONGLY RECOMMEND that you read books, trade magazines, or get formal training before beginning any projects. Regardless of the content in this section, Grizzly Industrial will not be held liable for accidents caused by lack of training. Power Controls It is vital that you become familiar with the power controls before operating the Model G0463. Three separate switches control the power on the mill/drill (see Figure 10). Figure 10. Control panel components. 5 7 4 3 1 6 2 1. EMERGENCY STOP Button: Immediately disconnects power to the system. Once pressed, this button must be twisted until it pops out to return power to the switches. The FAULT INDICATOR Light will turn on and the MAIN POWER Switch needs to be turned OFF. 2. FAULT INDICATOR Light: Indicates a circuit interruption due to a switch being out of proper position. Turn all switches OFF when lit. 3. POWER INDICATOR Light: Shines when the system power is ON. 4. Fuse Socket: Houses a 10 Amp system fuse. -18 G0463 Small Mill/Drill 5. SPINDLE RPM Control Knob: Turns the spindle ON and controls the spindle RPM in both speed ranges. 6. FORWARD/NEUTRAL/REVERSE Switch. Changes spindle rotational direction. 7. MAIN POWER Switch: This switch delivers power to the system. Power Shutdown It is important to shut the power OFF when the mill/drill is not in use. Leaving the power ON keeps the circuit board cooling fan running. This will cause unnecessary wear on the fan and electrical system. To completely shut the system power OFF: 1. Turn the SPINDLE RPM Control Knob OFF. 2. Turn the MAIN POWER Switch OFF. 3. Press the EMERGENCY STOP Button. At this point the green power light and the amber fan power light should not be lit. Spindle & Headstock Controls The Model G0463 spindle height is controlled like a drill press (see Figure 11). To use the rapid downfeed: 1. Make sure the quill lock is released and the headstock is locked in position. 2. Turn the quill feed levers to lower and raise the spindle. Note: For maximum rigidity and accuracy when milling, keep the spindle retracted and locked inside the head as far as possible. Figure 11. Spindle controls. Headstock Lock Quill Lock Quill Feed Levers The headstock moves on the column in the vertical (Z) axis and is controlled by a handwheel. To move the headstock: 1. Unlock the headstock lock. 2. Turn the vertical (Z) axis handwheel shown in Figure 12 to raise and lower the headstock. Note: For maximum rigidity and accuracy when milling, make sure you keep the headstock locked in position.
