Things You'll Need
Allen wrench set
Reciprocating saw blades move back and forth instead of in a circular rotating motion. This makes reciprocating saws a preferred tool for many projects because the saw gets into tighter positions than a saw with a large circular blade. Reciprocating saws accept various types of blades. Each blade cuts a different type of material, such as drywall, wood, metal or plastic. Blades get changed multiple times during some projects, and changing the blade is a quick, simple task.
Attachment Using Screwdriver or Allen Wrench
Unplug the reciprocating saw. Put on gloves. Choose the correct size Allen wrench from the Allen wrench set. Insert the socket in the hex-head screw socket close to the end of the reciprocating saw, or use a screwdriver if there's a regular screw head.
Loosen the screw counterclockwise without removing it. If there is a blade in the reciprocating saw, wiggle the blade back and forth while pulling the blade away from the socket. There is a hole cut into the blade that locks it in place when tightened, so wiggling the blade frees the blade from the notch in the clamp.
Attach the new blade with the teeth of the saw blade facing the same direction as the handle. Slide the blade into the clamp area. Wiggle the blade while pushing it in until you feel the blade catch into the notch.
Turn the Allen wrench clockwise until the screw tightens. Pull on the blade to make sure that it is secured tightly.
Attachment Using Quick Release
Locate the quick-release lever on the reciprocating saw. It is a flat metal or plastic lever at the end of the saw by the blade insert. Put on gloves.
Pull up on the lever and hold it. It is on a spring, and it will close if you aren't careful. If there is a blade in the reciprocating saw, remove the blade by wiggling it back and forth while pulling it away from the socket.
Push the new blade into the blade-holding socket clamp. Lower the lever. Wiggle and pull on the blade to make sure it is secure in the blade-holding socket clamp.
When changing a blade after it has been used, be careful, as the blade gets very hot from the friction.
Remember that the saw is sharp, and it will cut you even when it isn’t turned on.
