Changing the blade on a Chicago Electric reciprocating saw is a simple process, but it's important to follow the correct steps to ensure safety and efficiency. Reciprocating saws are versatile tools with a wide range of blades designed for specific materials, so knowing how to change the blade is crucial. The process begins with unplugging the unit for safety, followed by removing the current blade. Users then need to select the appropriate blade for the material they intend to cut and install it securely. This may involve choosing the right blade type, such as Diablo blades, and ensuring a tight fit with screws and bolts to prevent movement. With the new blade in place, the saw is ready to use and can be plugged back in.

What You'll Learn
Unplug the saw or remove the battery pack
Before changing the blade on your Chicago Electric Saw, it is important to unplug the saw or remove the battery pack. This is a crucial safety step as it prevents the saw from accidentally turning on and causing injury.
If your saw is corded, simply unplug the cord from the power source. Make sure you unplug it from the wall outlet and not just from an extension cord to completely disconnect the power supply. Visually inspect the cord for any damage, such as fraying or exposed wires, before plugging it back in.
If you own a battery-powered Chicago Electric Saw, you can remove the battery pack by locating the switch that releases the battery and clicking it to safely detach the battery from the saw. Ensure that you do not force the removal of the battery pack and only use the designated release mechanism.
Allow the saw to cool down before proceeding with any maintenance or blade changes. The blades of the saw generate a significant amount of heat during use, and handling a hot blade can result in burns. Wait a few minutes after use and consider wearing gloves for added protection when handling the blade.
By unplugging the saw or removing the battery, you ensure that the tool is completely deactivated and safe for you to work on. This step is fundamental to preventing accidents and ensuring your safety when changing the blade on your Chicago Electric Saw.

Remove the current blade
To remove the current blade from a Chicago reciprocating saw, start by unplugging the unit from its power source. If your saw is battery-powered, remove the battery pack by clicking the switch to release it. This is an essential safety step, as you don't want the saw to accidentally turn on while you're removing the blade.
Wait for the blade to cool down before proceeding. Blades generate a lot of heat during use, so give it a few minutes to avoid burning yourself. You can also wear gloves for additional protection.
Now, you're ready to remove the blade. Rotate the chuck counterclockwise and pull out the blade. Fully pull out the blade, then release the chuck. Be very careful not to cut yourself on the blade, and store it somewhere safe, like a toolbox.
If your saw is a Chicago Power Miter Saw, the process is a little different. First, remove the cover bolt using a socket wrench. Then, remove the cover screw with a T-20 star wrench. To unscrew the bolt holding the blade, press the "spindle lock button" to lock the blade in place. With the blade locked, unscrew the bolt by turning it clockwise. Finally, remove the guard and the blade.

Choose the right blade for the material
Choosing the right blade for your Chicago Electric Saw is crucial for safety and achieving the desired results. The selection of a saw blade depends on various factors, including the type of material, its thickness, structure, and hardness.
If you are working with wood, you will need a different blade than if you are cutting metal or masonry. For instance, a standard circular saw blade is typically used for cutting wood and comes in several varieties, including rip-cut blades, framing blades, crosscut blades, and plywood blades. Flat-top teeth are used on blades for ripping hard and softwoods, as they efficiently cut and rake material. On the other hand, if you are cutting metal, a bimetal band saw blade is a good choice for harder materials like titanium and zinc, as they offer fast and precise cuts while being durable.
The number of teeth on the blade also impacts the speed and finish of the cut. A blade with more teeth will yield a smoother cut, while a blade with fewer teeth will remove material faster. For example, a 10" blade designed for ripping lumber typically has around 24 teeth, allowing for quick material removal along the length of the grain. Conversely, a crosscut blade, designed for a smoother cut across the grain, will have 60 to 80 teeth, requiring a slower feed rate.
Additionally, the hook angle of the blade tooth affects the cut. A positive hook angle creates a faster and rougher cut, while a negative hook angle provides a less aggressive cut and a smoother finish. The thickness of the blade also matters; a thinner blade will give a finer, more precise cut.
It is important to remember that using the wrong type of blade for your saw can be dangerous and produce poor results. Always ensure you select the appropriate blade for the specific material you are working with and follow safety guidelines.

Install the new blade
Before installing a new blade, it is important to ensure that the saw is unplugged or the battery pack is removed. Once this is done, follow these steps to install a new blade in your Chicago Electric Saw:
Step 1: Choose the Right Blade
It is important to choose the right blade for the material you will be cutting. Using the wrong blade can lead to damage or accidents. Make sure to put on gloves for additional protection.
Step 2: Insert the Blade
With the old blade removed, carefully insert the new blade into the saw. Ensure that the blade is securely in place and will not come loose during use.
Step 3: Secure the Blade
After inserting the new blade, make sure it is locked in place. Depending on your saw model, you may need to use a spindle lock button or a chuck to secure the blade. Refer to your saw's instruction manual if you are unsure.
Step 4: Reassemble the Saw
Once the new blade is locked in place, reassemble any parts that were removed during the blade change process. This may include replacing guards, covers, or screws.
Step 5: Test the Saw
After the new blade is installed, plug the saw back in or insert the battery pack. Test the saw on a scrap piece of material to ensure it is cutting properly and that the blade is secure.
By following these steps, you can safely and effectively install a new blade in your Chicago Electric Saw, ensuring that your saw is ready for its next cutting task. Remember always to use the appropriate blade for the material you are cutting to maintain safety and maximize the life of your saw.
