Link,
Usually you will have to remove the blade guard to get access to that. There is usually a rubber stop with a screw going through it that you will have to remove, and a spiral spring clip on the inside of the hub of the blade guard that will also have to be removed and then you should be able to lift the blade guard off the saw. The spring will hook around the blade guard and the other end will hook to the saw housing. Hope this helps!

Just for your information there are not many parts available for this model any longer.

With that said, it may be something rather simple. I get this type of problem all the time. Does the blade have the diamond punchout still in the blade or has it been punched out? Make sure that the the type of mount is the same as the hole for the blade. Another thing to check is to make sure the clamp washer is there under the blade. This is the part that will have a raised lip that goes through the hole in the blade just enough to center it. If that is missing you can replace it with a new one: part #143783-00 . If those 2 solutions do not work, it is your main drive gear. The worm is probably ok but the gear is probably shredded. This part is unavailable and renders your saw useless.

How to reinstall saw guard on Mac Allister MAC185LS?


Never heard of this brand of saw. A Google search indicates that MacAllister only makes big earth moving equipment. Otherwise, most saws have an appropriate washer and retaining clip that holds the guard on. And you'll need the original spring to return the guard to the closed position every time you use it. Then there are two shaped washers that fit on the armature that have a 5/8" shoulder to fit a normal saw blade. Finally there is the nut that holds everything on. Hope you didn't lose all these parts. If you did, go to eReplacementparts.com and and enter your make and model. If they don't have what you need you might be plum out of luck. But a new saw.

What is the spring for in the 2000w makita circular saw


Other than carbon brush springs, the only other spring that I know of on a circular saw is for the blade guard so that it will automatically return to cover the blade after you make the cut. There should be a hook or a bend in each end of the spring and each end has a certain spot where it hooks so that it pulls the blade guard back in place.

How do I replace the blade guard on a Dewalt DC390K saw


Remove the clip behind the back blade flange holding it on to the housing and lift it up of the return spring, replace the opposite way remembering to relocate the return spring. Make sure you get the model number correct as the 390 and 390k are different.

How do I replace the spring on the retractable blade guard on a model 77 worm drive skilsaw?


Bearings maybe......I'd also check the armature fan and see if it came loose. Either way it doesn't sound cheap!

Can't find my owners manual. How do I change the blade. Bolt hits on a guard that covers the arbor. On a DW713 combination saw.


Removing the Blade
1. Unplug the saw.
2. Raise the arm to the upper position and raise the lower guard as far as possible.
3. Loosen, but do not remove guard bracket screw until the bracket can be raised far
enough to access the blade screw. Lower guard will remain raised due to the position
of the guard bracket screw.
4. Depress the spindle lock button (Fig. 3) while carefully rotating the saw blade by hand
until the lock engages
5. Keeping the button depressed, use the other hand and
the wrench provided to loosen the blade screw. (Turn
clockwise, left-hand threads.)
6. Remove the blade screw, outer blade clamp, and
blade. The inner blade clamp may be left on the
spindle.
Installing a Blade
1. Unplug the saw.
2. With the arm raised, the lower guard held open and the
guard bracket, place the blade on the spindle against
the inner blade clamp with the teeth at the bottom of
the blade pointing toward the back of the saw.
3. Assemble the outer blade clamp onto the spindle.
4. Install the blade screw and, engaging the spindle lock,
tighten the screw firmly with wrench provided. (Turn
counterclockwise, left-hand threads.)
5. Return the guard bracket to its original position and
firmly tighten the guard bracket screw to hold bracket
in place.
WARNING:
• The guard bracket must be returned
to its original position and the
screw tightened before activating
the saw.
• Failure to do so may allow the guard
to contact the spinning saw blade
resulting in damage to the saw and
severe personal injury

Replacing the blade guard spring


there is a hold in the lower guard for the loop and the other end wraps around the guard slightly and there is a hole in the back of the upper guard. You can go to Milwaukeetool.com and download a breakdown for the tool Also when you have the blade off I would try using compressed air to clean the area and spray some lubricant on the hub to lubricate. The guard should "snap" back when done sawing. Let me know if you need more help

How to get blade off


1. Unplug the saw.
2. Locate the blade lock button used to lock the motor shaft when changing a blade. For your saw, this button is usually located on the right side of the blade guard somewhere around the motor housing.
3. Push the button while rotating the blade until the button engages and the blade will no longer turn.
4. Use the wrench that came with the saw (or another wrench) to loosen and remove the blade bolt. For a worm drive saw with the blade to the left of the motor, the bolt should have left hand threads (non-standard) which means you loosen the bolt by turning it clock-wise.

I am missing the part that brings the guard back when you lower the saw blade


I am assuming that you have some type circular saw?
Most popular saws use a spring to return the guard,with the saw unplugged raise the guard and see if the spring is there(you may need to take off the blade) if it is not there,replace with proper spring.one end of the spring will hook onto the fixed 1/2 of the guard the other to the front of the moving guard(consult manual if possible).once this is done insure that the guard mover freely and is not in the way of the blade.Replace the blade in proper direction check guard again for proper travel,make sure everything has been re-tightened .
If the spring is there check for material build-up or debris that is causing
guard not to move,remove blade clean debris or obstruction,replace blade and check for proper operation.Also visually inspect where the moving guard is attached to the saw for any unusual marks or wear this could be a sign that some type of unsafe situation exists,if this happens refer to a pro to fix or buy new never use a saw without a properly working guard,it took 141 stitches to repair my friends leg.
