An electric door jamb saw is used when installing hardwood, ceramic or laminated floorings. It has a circular saw blade, a depth adjustment, and a table height adjustment, with the toll complemented with a slightly protruding handle for accurate and steady handling of the saw. Below are the steps on how to use the door jamb saw.

Step 1 - Adjust the Jamb Saw Blade

Using a piece of your flooring material as a guide, adjust the height of the saw blade. Make sure that the upper portion of the blade is aligned to the upper portion of the flooring material that you will be installing.

Step 2 - Adjust the Cut Depth

Adjust the cut depth of your saw blade slightly deeper than the depth of the door jamb that you are cutting. The ideal depth adjustment for the jamb saw blade is at least 1 mm deeper than the door jamb.

Step 3 - Check for Nails

Check your cut line for nails. Set the nails deeper than your cut by hammering the nail in using a hammer and a nail set. Make sure that all the nails in your cut line are deeper than your cut to avoid damaging the blades of your jamb saw.

Step 4 - Cut the jamb out

Lay the flooring pieces along with the underlayment padding on the floor directly adjacent to the door jamb. Turn on the jamb saw and allow the speed to regulate before cutting. Slide the jamb saw on the floor and aim the saw blade on the left side casing of the door jamb. Cut in a clockwise motion. Slide the flooring piece and the underlay beneath the jamb to make sure the cut is right. Cut the right casing of the door jamb the same way.
