Instructions for a Skilsaw 5150

Lisa Wampler

Skilsaw is a brand name owned by Bosch. The Skilsaw 5150 is a discontinued circular saw that uses a 17 ½-inch saw blade. This is a common size circular saw for Skilsaw as most of its high-end saws use this size blade.

Skilsaw does not change the functionality of its circular saws very much, so using a 5150 will feel the same as using just about any other Skilsaw.

  1. Disconnect the power plug from the outlet.

  2. Place the base of the Skilsaw next to the edge of the material you want to cut through. Slide the guide back to expose the blade.

  3. Slide the depth adjuster lock upward. It is located between the top saw-blade guard and the handle. Set the depth of the saw blade so the tip of the blade rests ¼ inch below the bottom side of the material you want to cut and then lock the depth adjustment lock. This will ensure you cut all the way though your lumber.

  4. Loosen the bevel adjustment wing nut located on the back of the saw and adjust it to 0-degrees. Flip the saw over and place a square on the base plate and the saw blade. Make any necessary adjustments to square the blade to the base plate and then tighten the wing nut. This will ensure a 90-degree cut on your wood.

  5. Make a measurement and scribe a line across the face of your board to indicate the cutting line. Use a contrasting color to the wood so you can easily see the line while cutting it.

  6. Secure the wood to a stable surface using clamps. Make sure the line you scribed does not rest on the table. You need clearance under the wood at this location for the saw blade.

  7. Plug the Skilsaw in and position the blade so it rests about 1 inch away from the wood you are cutting. Line up the blade indicator line on the front of the base plate with the line you scribed on the wood.

  8. Press the trigger to turn on the saw and make one smooth cut through the wood.
