the tool by its thermoplastic housing, and always wear eye protection when operating this device.

Step 1: Be certain that the box or fixture which requires a cut-out is firmly mounted and all wires or other obstructions around the opening are pushed back out of the way. The drywall cut-out bit uses the outer edge of the box or fixture as a guide, so it is important that there is nothing in the way which can prevent it from guiding completely around the opening. For the purposes of this instruction manual, the procedure discussed will be to make a cut-out around a standard 2 1/8" x 3 3/4" electrical box.

Step 2

Slide switch to turn the tool on. While holding the Spiral Saw power tool firmly with both hands plunge the Zip Bit through the mark you made. Then guide the Zip Bit to the right until you feel and hear the Zip Bit touch the inside edge of the box.

Step 3

Pull the Zip Bit out far enough to slip it over the edge of the box so it is now against the outside of the box.

Step 4

While keeping the Zip Bit in contact with the outside of the box move the tool counter clockwise while applying light inward and upward pressure until you feel and hear it come to the corner. As you round the corner apply light pressure left and downward.

Step 5

While moving slowly and continuously along the top contour you will feel the Zip Bit come to the next corner. Round the corner and apply light down and inward pressure until the bottom corner is reached.

Step 6

Move the Zip Bit right and upward maintaining light continuous pressure toward the box.

Step 7

Round the right bottom corner and begin moving the bit upward while applying light pressure left toward the box until you meet initial upward cut. Push Spiral Saw power tool switch to off.

Step 8

The completed box, executed quickly, neatly and in a fraction of the time taken by other methods.

These step-by-step instructions are generalized to acquaint you with the Spiral Saw power tool operation. After some practice, you may develop a motion technique with which you are more comfortable. However, you must always begin the cut somewhat centrally, and MOVE THE SPIRAL SAW POWER TOOL ONLY COUNTERCLOCKWISE to take advantage of the “hugging” action of the rotating Zip Bit along the contours of the template. Remember to use a smooth continuous motion.
