Introduction To The Chicago Electric 10″ Miter Saw
The Chicago Electric 10″ Sliding Compound Miter Saw is a sliding compound miter saw sold by Harbor Freight under item number 61971 (also sold over the years as 56708, 61972, 96697, 98199, 90891, 61307, and 57343 — these are the same basic saw with minor packaging or supplier changes, not different tools). Per the manufacturer’s specifications, it runs at 120VAC/15A, 5000 RPM, and uses a 10-inch, 5/8″-arbor blade with a cutting capacity of 2-3/4″ x 12″ at 0° and up to 45° miter and bevel angles. Like any power tool, its parts wear out and eventually need replacing.
Identifying Common Parts For Replacement
Per the official parts diagram, the parts that wear out or fail most often on this saw are the Blade, Blade Guard and Guard Plate, Carbon Brushes, Trigger/Switch assembly, Upper and Lower Handles, and the Kerf Board (the removable insert around the blade slot). Less commonly, the Sliding Rods, Linear Bearings, and Fence may need replacement after years of heavy use.
Blades And Blade Guards
This saw’s stock blade is a 10″ diameter blade with a 5/8″ arbor bore — any replacement blade must match both measurements. Per the manual, the saw is intended to cut wood and wood-like products only; it is not rated for cutting ferrous metal with abrasive cut-off wheels, since abrasive dust and sparks can jam the lower guard and burn the kerf board and other plastic parts.
| Use Case | Blade Type |
|---|---|
| General framing, rough cuts | 24-40 tooth carbide |
| Fine trim, molding, cabinetry | 60-80 tooth fine-finish blade |
| Plywood, veneered material | 80+ tooth, low tooth angle |
The Blade Guard and Guard Plate protect your hands from the spinning blade and must operate smoothly — the manual specifically warns to confirm the lower guard raises and returns properly every time before use. If a guard is cracked, doesn’t spring back on its own, or is missing its return spring, replace it before using the saw again.
📊 In February 2023, Harbor Freight recalled about 7,175 replacement lower blade guards sold for the 12-inch Chicago Electric miter saw (item 61970, serial numbers under 370331936) because the guards could break and fail to cover the blade during a cut. This recall does not cover the 10-inch saw (61971/56708) this guide is about — but it’s a good example of why a cracked or ill-fitting guard should never be used, on any miter saw. — Source: U.S. CPSC Recall Notice (2023)
Handle, Trigger, and Switch Assembly
The saw’s handle assembly is made up of the Upper Handle, Lower Handle, Trigger, Trigger Lock, and Switch — these are separate parts in the official diagram, not one single unit, so it helps to know exactly which piece has failed before ordering. A saw that won’t start is most often a worn Switch or Trigger, not a motor problem: the manual’s own troubleshooting table lists a damaged cord, no power at the outlet, a tripped thermal reset, or worn Trigger/Switch internals as the four most likely causes, in that order.
If the saw runs but feels weak or noisy, worn Carbon Brushes are the most common cause — the manual specifically calls out “performance decreases over time” and “excessive noise or rattling” as classic carbon brush symptoms, and recommends having a qualified technician replace them rather than DIY unless you’re comfortable opening the motor housing.
“Have your power tool serviced by a qualified repair person using only identical replacement parts. This will ensure that the safety of the power tool is maintained.”
Throat Plate (Kerf Board) Replacement
What Harbor Freight calls the “Kerf Board” is the removable insert plate around the blade slot — it’s held on by four screws and should be replaced once it’s chewed up enough that the workpiece no longer sits flat against it. After installing a new one, lower the blade, lock it down, and adjust the board so the blade just clears its edge at both 0° and the maximum 45° bevel angle before retightening the screws.
Saw Stands And Mounting Accessories
This saw can be bolted directly to a bench using its four base mounting holes, or mounted to a dedicated rolling or folding miter saw stand for portability. A stand with quick-release brackets makes it easy to pull the saw off for storage between jobs without unbolting anything.

Where To Buy Replacement Parts
For blades, dust bags, and generic hardware, Amazon and eBay carry compatible parts that match this saw’s specs (always check the arbor size and diameter before buying a blade). For parts specific to this exact saw — the molded plastic Guard Plate, the Handle assembly, or the Kerf Board — Harbor Freight’s own parts department is the most reliable source, since these parts are sized to this saw’s exact tooling and aren’t widely reproduced by third parties. The manual notes that some internal parts are shown for illustration only and aren’t sold individually, so a full sub-assembly replacement is sometimes the only option.
DIY Repair And Maintenance Tips
How To Change The Blade
- Unplug the saw and lock the blade in the raised position using the Locking Pin.
- Remove the Guard Plate Bolt and Connecting Rod Bolt, then raise the Blade Guard and Guard Plate.
- Hold the Spindle Lock Button in and loosen the Arbor Bolt with the supplied wrench — note it has a left-hand thread, so it loosens clockwise.
- Pull the Arbor Bolt, Outer Flange, and old blade off the spindle (leave the Inner Flange in place).
- Install the new blade matching the direction arrow to the housing, replace the Outer Flange and Arbor Bolt, then lower the guard and replace both bolts.
When To Replace Parts: replace the blade once cuts start tearing out or burning the wood; replace carbon brushes once the saw runs noticeably weaker or louder than normal; replace the guard immediately if it’s cracked, sticks, or doesn’t return on its own — never operate the saw with a guard that isn’t functioning correctly.
Safety Precautions For Part Replacement
- Always unplug the saw before changing the blade, guard, or any other part.
- Never cross your hands over the blade’s cutting line while operating the saw — keep both hands on the same side.
- Use only identical replacement parts, and have a qualified technician handle internal motor repairs (brushes, switch, bearings) if you’re not comfortable opening the housing yourself.
- After any repair, verify the lower blade guard raises and returns smoothly before making a test cut.
Frequently Asked Questions
How Do You Unlock A Chicago Electric 10 Miter Saw?
Push in the Locking Pin (used to hold the blade assembly raised for storage or blade changes) to release it, then raise the saw head. Confirm the Trigger Lock is disengaged before operating.
How Do You Change The Blade On A Chicago Electric Miter Saw?
Unplug the saw, lock the blade raised with the Locking Pin, remove the Guard Plate Bolt and Connecting Rod Bolt, loosen the Arbor Bolt (left-hand thread, loosens clockwise) while holding the Spindle Lock, then swap the blade and reverse the steps.
What Are The Parts Of The Miter Saw?
Per the official diagram, the major parts include the Trigger, Trigger Lock, Blade, Lower Guard, Fence, Sliding Fence, Miter Lock Handle, Miter Lever, Table, Kerf Board, Upper and Lower Handles, Carbon Brushes, and the Motor Housing assembly.
Was The Chicago Electric 10″ Miter Saw Recalled?
Not this model. The February 2023 CPSC recall covered replacement lower blade guards sold for the 12-inch Chicago Electric miter saw (item 61970), not the 10-inch saw (61971/56708) covered in this guide. Always check your saw’s exact item number on its label before assuming a recall does or doesn’t apply.
When Should You Cross Your Hands Over While Cutting On The Miter Saw?
Never. The manual explicitly warns against supporting the workpiece “cross-handed” (holding it on the opposite side of the blade from your cutting hand) because it puts your hand directly in the blade’s path if the workpiece shifts.
Conclusion
Whether it’s a worn blade, a cracked guard, or weak carbon brushes, matching the exact part — by name and by this saw’s official parts diagram — is what keeps a repair safe and effective. For generic parts like blades and dust bags, Amazon and eBay work fine; for saw-specific plastic and hardware, Harbor Freight’s own parts department is the more reliable source.
