In the event of damage in transit, contact Harbor Freight Tools immediately. 2. Read the owner’s manual and become familiar with the parts and controls on the drawings before using this machine, as familiarity with the controls will enhance your ability and safety in using it. INSTALLATION 1. It is important that the machine be located on a hard, solid, level floor. Find a location that supplies easy access to 110 Volt electrical service. Make sure this machine is located in a well lighted and well ventilated area. The floor should be resistant to vibration. 2. Before moving the machine, be sure the head is fixed on the column. Before moving the machine, lower the head as much as possible to lower the center of gravity. When moving the machine be careful to keep it balanced, and not allow it to topple over. 3. To set the machine on a solid concrete foundation, it’s advisable to apply a little grout to touch up any uneveness in the concrete in order to get a solid foundation at all points. 4. When setting machine on a floor that has any surface irregularities, shims should be used to correct this condition to the greatest extent possible. 5. There are 4 holes in the base for mounting the machine permanently to a smooth, solid, and level floor. CLEANINGAND LUBRICATION 1. Thoroughly clean the machine with a commercial degreaser. Do not use gasoline, kerosene or other flammable liquids. Avoid getting solvent on rubber parts, or into the electrical controls or motor. 2. After cleaning, coat all bright metal with a light lubricant to prevent corrosion. 3. Lubricate all points indicated in Figure 2 with a 10 weight machine oil. 4. Remove the oil filler plug and fill the reservoir with heavy motor oil, until the oil level reaches the middle of the oil fluid level indicator. Replace the plug. LEVELING THIS MACHINE 1. Before operation, it is critical to level the work surface both lengthwise and crosswise, using a precision level. It will not be possible to maintain accuracy of machined parts if the mill is not properly leveled to start. Figure 2. Lubrication Points. Page 6 SKU # 42827 BASIC OPERATION Prior to Operation 1. Check the oil level, and if necessary fill to the mid point of the oil level window. Basic Controls Please refer to Figure 1 on page 5. 1. Raise and lower the Head by using the Head Crank (#4). 2. Feed the Spindle using Spindle Feed Handle (#16). Precise movements may be made using the Spindle Micro Feed Handle (#15). 3. Move or feed the table from side to side by using the Table Feed Wheel (#7). 4. Move the Table front to back using the Cross Table Feed Wheel (#13). Adjusting the Head 1. To raise or lower the head, loosen the 2 heavy duty head lock nuts shown in the left part of Figure 3. Use the left side head handle to raise or lower the head on its rack and pinion mechanism. 2. The head may be rotated 360O by loosening the same bolts mentioned in item 1. Adjust the head to the desired angle, then fix the heavy-duty head lock nuts. Periodically check the tightness of these nuts, especially during prolonged use of the machine. 3. You may set the head at an angle by loosening the three nuts shown in the right part of Figure 3. Retighten the nuts when you have set the angle at the desired degree. Refer to the scale on the right side of the head to read the angle. Preparing for Drilling Please see Figure 4. 1. Rotate the knob in the center of the spindle feed handle (#16) counterclockwise to loosen the spindle for vertical travel. 2. You can move the spindle vertically by operating the spindle feed handle. 3. For more precise movement of the spindle, operate the micro feed handle (#15). 4. For drilling blind holes (which do not pass through the workpiece), set the positive depth stop gauge (#14). To do so, first determine the desired depth. Then adjust the positive stop gauge so that the distance from the tip of the drilling bit to the ...
