24) when first turning a jigsaw on, one should:

Simple

Always make sure you are using the right blade for the material. Make sure you put on safety goggles and use THICC gloves. DO NOT start cutting when children are around, as it is possible they may get hurt.

"1

Plug in the saw or put in the battery pack. Once you have your saw blade secured, plug the cord into a nearby outlet so you can reach all the areas you need to cut. If you have a cordless jigsaw, insert the battery pack into the port on the back of the machine.[7]  

Whenever you aren’t using your jigsaw, unplug it so you don’t accidentally turn it

Coil the cord once around your dominant arm so the cord doesn’t hang down loosely.

2

Wear safety glasses and a dust mask. Before you make any cuts, cover your mouth and nose with a face mask so you don’t inhale any dust. Protect your eyes with safety glasses in case any of your material kicks back towards you.[8]  

3

Clamp your material to your work surface so it doesn’t move around. Make sure the area where you plan on making your cuts extends over the edge of your work surface. Use at least 2 C-clamps on the edge of your work surface to hold the material sturdy. If it still moves around easily, use additional clamps or rest a heavy object on the opposite end of the material.[9]  

If you need to cut a hole in the center of your material, balance it between 2 sawhorses so you can easily cut through it without damaging your work surface.

You don’t need to use clamps if you’re making a vertical cut on a wall."
