2. Mark Your Lower Line
Use a straight edge and a pencil or marker to mark the road the place you wish to lower. Make sure that the road is straight and that it’s perpendicular to the sting of the insulation.
3. Set the Depth of the Blade
The depth of the blade must be set in order that it cuts by means of the insulation however not into the floor under. To set the depth of the blade, loosen the knob on the aspect of the noticed and modify the blade to the specified depth.
4. Slicing the Insulation
Maintain the noticed firmly with each fingers and place the blade on the lower line. Slowly decrease the noticed into the insulation and start slicing. Remember to hold the noticed straight and to use even stress as you chop. If you’re slicing a thick piece of insulation, chances are you’ll must make a number of passes with the noticed.
| Blade Sort | Tooth per Inch |
|---|---|
| Effective-tooth blade | 10-14 TPI |
| Medium-tooth blade | 6-10 TPI |
| Coarse-tooth blade | 4-6 TPI |
After getting completed slicing, flip off the noticed and permit the blade to come back to a whole cease. Take away the noticed from the insulation and examine the lower. If the lower shouldn’t be straight or if there are any ragged edges, you should use a utility knife to trim the insulation.
