6. Use the right tool for the job. Do not attempt to force a small tool or attachment to do the work of a larger industrial tool. There are certain applications for which this tool was designed. Do not modify this tool and do not use this tool for a purpose for which it was not intended. 7. Dress properly. Do not wear loose clothing or jewelry as they can be caught in moving parts. Protective, electrically nonconductive clothes and nonskid footwear are recommended when working.
19. Do not operate tool if under the influence of alcohol or drugs. Read warning labels on prescriptions to determine if your judgment or reflexes are impaired while taking drugs. If there is any doubt, do not operate the tool. 20. Use proper size and type extension cord. If an extension cord is required, it must be of the proper size and type to supply the correct current to the tool without heating up. Otherwise, the extension cord could melt and catch fire, or cause electrical damage to the tool.
9. Do not mount (or adjust) the workpiece on the Drill Press Table while the motor is running. 10. When drilling or cutting large holes, use the slower speeds and securely fasten the workpiece to the table using a mounted vise. 11. Do not use drill bits that extend more than six inches from the Chuck. 12. Do not use circle cutters, rotary planers, wire wheels, router bits, or shaper cutters on this Drill Press. Unpacking When unpacking, check to make sure the following parts are included.
4. Install the Table Support (C1), with attached Table (C7), over the Support Tube (C3) and slide it down. Hand Tighten the Lock Handle Support (C2). CAUTION: Avoid injuries. The next step involves lifting the Head Assembly onto the Support Tube. The Head Assembly is heavy. Have someone help you lift this assembly into place. 5. Using two people, lift the Head (1) Assembly up and onto the Support Tube (C3). Slide it down on the Column Tube as far as it will go.
- Slide the Chuck onto the Spindle Shaft. - Turn the Chuck sleeve clockwise and open the jaws completely. - Tap the nose of the Chuck lightly with a piece of wood and a hammer to securely set the Chuck. 11. Verify that the Table (C7) is square (90 degrees) to the Head Assembly and drill bit. - Raise the Table to within four inches of the Chuck. - Place the long side of a combination square on the Table. - Align the short side of the square to the drill bit.
Setting the Depth Scale to Drill to a Specified Depth During this procedure, refer to the left photo on page 6. 1. Make sure the Drill Press is OFF and Power Cord (33) is unplugged. Secure the workpiece to the Table. 2. Mark the desired hole depth on the side of the workpiece. Also view the depth indicator Pointer (32) shown on page 9. 3. Loosen the Hex Nuts (31) and screw both toward the top of Stop Rod (B12). 4.
2. Slide the Spindle Shaft and Chuck assembly up and into the Quill Tube (B3). At the same time, turn the assembly until the rectangular end of the Spindle Shaft slips into the notch on the Quill Tube. Warning: In the previous step, if the Spindle Shaft is not properly set in the Quill Tube notch, it may fly out during operation. 3. Loosen the Lock Handle Support (C2) and raise the Table (C7) about three inches below the Chuck. 4. Turn the Chuck sleeve clockwise to open the jaws completely. 5.
8. Pull the Feed Knob and check the spring tension, making sure the up movement is smooth and complete. From one inch down, the Chuck should return to its uppermost position. If more tension is required, repeat steps. 9. Replace the (outer) Hex Nut and tighten on top of the (inner) Hex Nut. Do not overtighten. 10. If the (up/down) movement is restricted, slightly loosen the (inner) Hex Nut, and retighten the (outer) Hex Nut. General Maintenance 1.
