The blade lock on a Craftsman circular saw is located on the side of the saw near the blade. There is typically a small lever or button that needs to be pushed or pulled to unlock the blade and allow you to change it out.
It is important to ensure that the blade is securely locked in place before use. Additionally, if you are having difficulty locating the blade lock, refer to the user’s manual for the specific model of saw you are using for directions.
How do you remove the blade from a circular saw?
Removing the blade from a circular saw will depend on the specific make and model of your saw. Generally, the process should involve:
1. Unplug the saw’s power cord to avoid any potentially dangerous accidents.
2. Flip the saw upside down, so the blade is facing upwards.
3. Use an appropriate sized Allen wrench to loosen and remove the blade plate bolt.
4. Lift the blade plate off the saw to expose the arbor nut. Be careful to keep track of any washers that have been removed from this step.
5. Use an appropriate sized wrench or socket to loosen and remove the arbor nut, being careful to keep a good grip on it as you will be spinning it off the shaft.
6. Once the nut has been removed, the blade can be lifted off the saw. Take extra care when handling the blade to avoid any potential injuries.
7. Once the old blade has been removed, clean the blade plate, washers, and arbor, and put any anti-seize lubricant on the threads of the arbor before installing a new blade.
8. Place the new blade onto the saw on the arbor and use the appropriate sized wrench or socket to tighten the arbor nut back onto the shaft.
9. Put the blade plate back onto the saw and use the appropriate Allen wrench to secure it in place. Plug the saw back in and you are ready to start cutting.
Are circular saws reverse threaded?
No, circular saws are not reverse threaded. The blade of a circular saw is mounted with the teeth pointing outward, so the threaded fasteners go in the same direction. This creates a forward rotation when the saw is powered up.
In contrast, reverse threading requires that the threads point inward, which would not work with a circular saw blade.
Why does my circular saw blade stop spinning?
There could be a few reasons why your circular saw blade is not spinning. One of the most common issues is a broken or worn out power cord or switch. If the power cord or switch are not functioning properly, the motor will not turn on and the blade will not spin.
Another possible cause could be that the saw blade is not installed properly. Make sure that the blade is securely attached to the arbor and the arbor is firmly held in place by the saw’s washer and arbor nut.
In addition, it is possible that the motor inside the circular saw has burned out. When the motor no longer spins properly, the blade will not spin either. It is also important to make sure that the blade is kept clear from any debris or sawdust that may be blocking the blade from turning freely.
Lastly, the saw blade may be broken or worn down from too much use and should be replaced.
How do I change a circular saw blade?
Changing a circular saw blade can seem intimidating, but it’s actually fairly simple. Before getting started, make sure to disconnect the saw from any power sources and properly wear safety goggles as well as other protective equipment before attempting to change the blade.
Next, use the wrench provided with the saw to loosen the blade clamp located at the back of the saw. Depending on the type of saw, the clamp can be loosened by turning it either clockwise or counterclockwise.
Once you have completely loosened the blade clamp, the blade can be removed from the saw.
Then, place the new blade on the saw, making sure that the teeth of the blade are pointed in the same direction as the motor so that the blade starts spinning in the right direction when it is running.
Make sure to also align the appropriate arbor holes of the new blade with the arbor/spindle of the saw.
The last step is to tighten the blade by using the blade clamp. Make sure not to over-tighten, as this could cause the blade to become unbalanced and impact the saw’s performance. Once the blade has been tightened and is securely in place, it is now ready to be used.
Which way do the teeth go on a circular saw?
The teeth on a circular saw should always go in the same direction, typically counter-clockwise. This is due to the spinning motion of the disc and guard, which creates a suction against the material being cut as it pulls the material through the blade.
When using a circular saw, you should always ensure the blade is rotating in the proper direction, according to the manufacturer’s guidelines, which are typically indicated with an arrow on the side of the saw.
To do this properly, you should always make sure the saw housing is tucked away, otherwise the spinning blade can cause harm to both you and the material you are cutting. It is important to note that some circular saws are designed to run in both directions.
If a saw is designed to cut in either sense, make sure to check the manufacturer’s instructions before starting the saw.
Which way should a saw blade face?
The saw blade should face the direction of the cut. The teeth of the saw blade are designed to cut in the direction of the arrows stamped on the side of the blade. It is important to make sure that the saw blade is installed in the direction of the arrows and the handle is pointing away from you.
This will ensure that the blade is cutting in the direction it is designed to and that it is safe to use. When making a bevel or angle cut it is important to make sure the blade is tilted to the correct angle before starting the cut.
Doing so will ensure that the saw blade is angled to cut the material and will not bind, jump, or kickback. It is also important to ensure that the saw blades are changed regularly, as dull blades can lead to kickback and cause dangerous situations.
Is there a left and right handed circular saw?
Yes, there are left and right handed circular saws on the market. Left-handed saws operate in reverse compared to a standard right-handed saw — when viewed from the side, the blade rotates counter-clockwise.
This allows left-handers to more easily follow the cutline they are making, as they can better see the blade and the cut line. Right handed saws rotate clockwise as viewed from the side. A left-handed saw also places the sawdust outside of the operator’s line of sight, instead of in the operator’s face like a right-handed saw.
Both right- and left-handed saws typically feature a switch to reverse the direction of the blade. Whichever saw you opt for, make sure to wear safety gear, such as safety glasses, gloves, and a hearing protector.
Why are some circular saw with blade on left?
Circular saws with the blade on the left have several features that may be beneficial to some users. One key feature is improved cutting capacity and accuracy. Because the blade is on the left and your dominant hand is usually on the right of the saw during operation, the motorized blade and your dominant hand work together in natural harmony — allowing you to make efficient, accurate cuts.
Additionally, it allows the user to better see what they are cutting as you tend to get a better view of the workpiece when cutting from left to right.
Another advantage of having the blade on the left is that it creates a better weight balance. Since the heavier components of the saw (i. e. , the motor and blade) are on the left side of the saw, the weight is more evenly distributed along the saw handle.
This improved weight balance reduces user fatigue, especially for those making more cuts or for longer periods of time.
Finally, having the blade on the left may benefit left-handed users. As a left-handed user, you wouldn’t need to adjust yourself or the saw to accommodate your dominant hand. This can be especially helpful to those in carpentry professions that require tight precision during operation.
Why do circular saws cut upwards?
Circular saws cut upwards due to the design of the saw blades themselves. The blades have teeth on the cutting edge which rotate in an upward direction when the saw is turned on. This upward motion helps to push the material being cut away from the cutting surface, making it easier for the saw blade to cut through the material.
Since the teeth move in the same direction as the blade rotation, the saw blade will be forced to cut upwards. This more efficient cutting technique helps to reduce the risk of kickback and other potential hazards.
In addition, cutting upwards also reduces the amount of material that is lost in the cutting process, resulting in smoother and more precise cuts.
Why is worm drive saw better?
Worm drive saws are commonly regarded as being superior to other types of saws because of their superior power and performance. The secret to the saw’s performance is the gear configuration design, which provides a greater speed, torque and cutting power than other saws.
This is mainly because the gear ratio of worm drive saws is much higher than other saws – typically 7:1 compared to 2:1 in other saws. This higher gear ratio gives the saw more power to speed up thereby increasing the cutting power considerably.
Additionally, worm drive saws are built more stoutly to withstand the heavy torques generated by their motor. This makes them less susceptible to kickback, and more importantly less prone to failure.
The oil-bath lubrication also ensures greater durability, better heat dissipation and longer life. Finally, worm drive saws are designed for cutting through heavy, dense materials like plywood, banks and slots, whereas other types of saws generally cannot handle such cuts without requiring a lot of effort.
This makes the worm drive saw an ideal choice for contractors and serious DIYers who work with dense materials frequently.
