Operation

Refer to FIGURE 1 on page 4.

Warning! Always unplug the unit when changing bits.

Warning! After drilling or driving screws, the bit will be extremely hot. Do not touch it until it has had ample time to cool down.

1.Insert the Chuck Key (#41) into one of the holes in the Chuck (#3) and turn it coun- terclockwise to open the jaws.

2.Insert the bit and hand tighten it, then tighten it with the Chuck Key (#41) by turning it clockwise.

3.With heavy leather gloves on, tug on the bit and make sure it is securely attached. Check that it is straight.

Note: Always use sharp bits. Dull or damaged bits may cause undue stress on the drill and possibly break causing injury. Bits are available at Harbor Freight Tools.

4.Securely clamp your workpiece.

5.Locate the Side Handle on the desired side of the tool.

Drilling

6.When drilling wood, place the bit at the point to be drilled. If you are drilling a hard, smooth surface, use a punch to mark the drill location. Set the Directional Switch forward. Grasp the handles firmly with both hands and slowly squeeze the Trigger (#34). Never operate the tool without the side handle. Never force the tool. Only apply light pressure when horizontal drilling. If you need more or less torque, use the torque adjustment on the top of the drill.

Note: When drilling plastics or plastic coated chip board, follow the same directions as stated in number 5 for wood.

Note: If a bit becomes wedged into the workpiece, stop and change the Directional Switch to the reverse position. Then slowly squeeze the Trigger to back the bit out of the work piece.

7.When drilling metal, always use a punch to mark the drilling position. Use a lubricant to prolong the life of the bit and increase the drilling action with most metals. With steel, tin, and sheet metal use a light machine oil, with aluminum, use paraffin. Do not use lubricants with brass, copper, and cast iron. Grasp the handles firmly with both hands and slowly squeeze the Trigger (#34). Never operate the tool without the side handle. Never force the tool. Only apply light pressure when horizontal drilling.

8.When driving screws, use bits suitable for the type and size of screw you are using. Drill a pilot hole for the screw head to bite into. Use the lowest torque setting. Grasp the handles firmly with both hands and slowly squeeze the Trigger (#34). Never force the tool. To back out a screw, stop and change the Directional Switch to the back posi- tion.
