To reattach the return spring on your Hitachi C12LSH miter saw, follow these steps:

1. Ensure that the miter saw is unplugged and turned off for safety.
2. Locate the yellow protective cover on the miter saw. This cover is designed to shield the blade when the saw is not in use.
3. Look for the small metal hook or attachment point on the yellow cover where the return spring should be connected.
4. Inspect the return spring itself and identify the end that needs to be attached to the yellow cover.
5. Align the end of the return spring with the attachment point on the yellow cover.
6. Apply pressure and securely attach the end of the spring to the attachment point. It may require some force to hook the spring into place.
7. Once the spring is properly attached, test the yellow cover by pulling it away from the blade. It should spring back into place when released.

If you are having difficulty locating the attachment point or need further assistance, consult the user manual for your Hitachi C12LSH miter saw. The manual should provide specific instructions and diagrams for reattaching the return spring. If you don't have the manual, you can usually find it on the manufacturer's website or by contacting Hitachi customer support.

If your Hitachi C10FS compound miter saw is running unsteadily and the power cuts in and out constantly even after installing a new switch and brushes, there may be a few possible reasons for this issue: Loose or damaged connections: Check all the electrical connections in the saw to ensure that they are properly connected and not damaged. Loose or damaged connections can cause intermittent power cuts. Faulty power cord: The power cord could be damaged or have a loose connection, which can cause the power to cut in and out. Inspect the power cord carefully, and if necessary, replace it with a new one. Faulty motor: If the motor is faulty or damaged, it can cause the power to cut in and out. You may need to have the motor repaired or replaced. Electrical interference: If the saw is being used in an environment with high levels of electrical interference, this can cause the power to cut in and out. Try moving the saw to a different location to see if this resolves the issue. If you have checked all of these potential issues and the problem persists, it may be best to take your saw to a professional for further diagnosis and repair.

If you can hear the motor engaging but the blade is not turning, there could be several possible reasons for this issue. Here are a few things you can try to troubleshoot the problem: Check the power supply: Make sure the saw is properly plugged in and the outlet is functioning. You can also try plugging the saw into a different outlet to see if that makes a difference. Check the blade: Make sure the blade is properly seated and tightened on the arbor. If the blade is loose, it may not spin properly. Check the belt: If your miter saw is belt-driven, check the belt to make sure it is not loose or broken. Check the motor: If the motor is running but the blade is not turning, it could be a problem with the motor. Check to make sure the motor is properly connected to the blade and that the motor is running smoothly. Check the electrical brake: If your miter saw has an electric brake, it may be malfunctioning. You can check this by unplugging the saw and removing the blade. Then, turn the saw on and see if the brake engages. If it doesn't, the brake may need to be replaced. If none of these troubleshooting steps solve the problem, it may be best to take your saw to a professional for repair.

If your Bosch 3915 compound miter saw is making a grinding sound when it slows down, it could be an indication of a few different issues. Here are a few things you can try to fix the problem: Clean the saw blade: A dirty saw blade can cause the saw to make a grinding sound. Use a brush or compressed air to remove any debris or sawdust from the blade. Check the blade for damage: A damaged or worn blade can cause the saw to make a grinding sound. Check the blade for any chips or missing teeth, and replace the blade if necessary. Check the bearings: The bearings on the saw's motor and blade can wear out over time, causing a grinding sound. Try to move the blade side to side to check for any play or looseness. If the bearings are worn, they will need to be replaced. Check the motor brushes: The motor brushes on the saw can also wear out and cause a grinding sound. Check the brushes for wear and replace them if necessary. Lubricate the saw: Lack of lubrication can cause the saw to make a grinding sound. Use a lubricant designed for power tools to lubricate the blade and other moving parts of the saw. If none of these steps solve the problem, it's best to take your saw to a professional for repair. Grinding sounds can be an indication of serious issues, and it's important to address them before they cause further damage to your saw

check to see if something is in the blade causing it to stop.. try removing the blade then see if the motor will run without it ..

Check the brush holders and make sure the brush can travel freely all the way down to the commutator. Look down the brush tube with a light and turn the blade to rotate the armature - look for missing/burnt segments on the commutator. Also, this has a soft-start module that can go bad - if the brushes and armature are good, switch rings out, and all connections are tight, I would lean toward the module.

You bypass the breaker in question by connecting the saw to an outlet connected to a different breaker; or by swapping two breakers out and see if the problem moves to the other circuit.

I have a Chicago tile saw tc250b the motor spins by hand the belt spinning but the motor is just humming what is that

Question edited for clarity. Question moved from Laundry Dryer. Replace the start capacitor on the motor. The classis reason for humming and not spinning. The start capacitor gives the motor a jolt to get it running. https://www.google.com/search?q=Hitachi+table+saw+start+capacitor ..

THEY DONT HAVE BRUSHES ITS A ELECTRIC MOTOR SMALL ONE PART 28 I WOULD THINK THE PROBLEM LIES BEFORE THE MOROR IN THE CIRCUIT OR THE MOROR NEEDS REPLACING PRICES ON THE WEB PAGE IN THE PIC

K9602724017 will work with some minor bending of the mounting tangs and matching up wires. I bought one on ebay a couple years back.

It seems that the trigger is fault.

It is part 112 on the parts schematic but gives no indication https://www.ereplacementparts.com/hitachi-c10fcb-compound-miter-saw-parts-c-7927_13297_13413.html Manual doesn't show either https://www.hikoki-powertools.com/manual_view_export/pdf/H99322813_C10FCB_405.pdf Aha, a Service and Repair Manual. Perhaps that will help? https://www.manualslib.com/manual/799928/Hitachi-C-10fch.html#page=23-manual ..

Only checking the circuit with a multimeter will find the fault and that means the saw will need at least partially dismantling. Internal breaks in the power cord is a common problem with tools and appliances and is a good place to begin...

replace the switch of course
