Dewalt Thickness Planer Operating Instructions
- 1). Set the depth of the cut you want to make. The adjustment wheel to move the cutter is located on the right side of the planer. Use the depth gauge on the front of the planer to set the desired thickness of the board. Measure how much of the wood will be removed by using the material removal gauge. Slide about three inches of the workpiece under the center of the planer carriage and note the indicator on the material removal gauge. This will tell you how much wood is going to be removed by the cutters in the current position. The maximum that you should remove on one pass is 1/8 inch. Remove the workpiece from the gauge.
- 2). Turn the motor on by lifting the On/Off switch on the front of the planer. Adjust the speed setting to setting "2" to remove material more quickly or to setting "1" to make a slower cut that is finer and smoother. Place the workpiece on the table and gently feed the workpiece into the planer until the feed rollers contact the workpiece and begin to draw it into the cutters. Position the wood so the cutters cut against the grain. Retrieve the workpiece on the other side of the planer.
- 3). Turn off the planer. Set the height of the cutter heads by using the thickness gauge on the side of the planer cradle. Use the thickness removal gauge to verify the amount of wood being removed. Flip the workpiece over so the opposite side is facing the cutters. Turn the planer On and feed the wood into the cutters. Retrieve the workpiece on the other side of the cutter head.
- 4). Change the planer knives and cutters when they become dull or worn. When this happens, you may notice motor overloading or excessive tear-out on the wood. The planer may also stop feeding the workpiece on its own. Use the provided T-wrench to remove the screws in the top of the planer. Remove the wing nuts that hold the dust shroud onto the planer. Rotate the dust shroud upward and push it to the left to remove it. The cutter head is now exposed. If you cannot see the eight retaining screws in the cutter, use a piece of scrap wood to turn the cutters until the eight screws are on top.
- 5). Remove the eight screws in the cutter using the T-wrench. Use the magnet on the top of the T-wrench to remove the blade holder and the knife blade without touching them if possible. If only one side of the knife is worn, turn it over so the sharp side is facing down. If you have done this once already, the cutter blades will need to be replaced. Tighten the eight bolts. Push the head lock lever and use the scrap wood to turn the cutter head to expose the second knife. Continue the process to finish the second cutter as well as the third.
