Whether you’re a professional woodworker or a casual DIYer working on a Dewalt model, knowing how to unlock a Dewalt miter saw is necessary. 

The unique features of the newly released models make unlocking a little complicated, but it’s one skill you need to master to work on this saw profusely.  

What to Do First

Familiarize Yourself With the Saw

Saws vary inbuilt, brands, and locking mechanisms. Acquainting with your saw, the manual, and other brand guides will help you get familiar with your saw’s operation, and the common mishaps, especially when you want to unlock your miter saw.

Remove Any Hazards in Your Shop or Space

Eliminate all hazards in your shop or working space, such as power cords. Safely store your cords to avoid trips and accidents. 

Ways of Unlocking Your DeWalt Miter Saw

Miters have different locking systems depending on the model and the brand. Some have knobs and locking pin, and knowing the different locking system that works for the different points, is vital when working with your miter saws.

Remember that you can’t apply the same technique to every brand or model. It’s a simple task, but the technicalities are essential to avoid damaging your power tool.

1. Unlocking the Head Using the Lock Pin

The handle connects to the rail, which is made of thick metal, and there’s a small metal pin that you can find easily on new models. Use a lever at the guide rail’s end to adjust the cutting angle. 

Older models, however, have the pin on the exterior side and usually look like a knob. This small knob keeps heat locked onto the machine. To unbolt this, turn it counterclockwise and rotate the knob clockwise if you want to push it in.

2. Unlocking Using the Down Lock and Push Lock

Most of the saws you will find, such as a Dewalt miter saw, have a down lock, and using a simple knob can move this lock. 

You must move this knob and apply a gentle push to unbolt the saw. Also, you can pull the lock to unlock your miter saw. 

3. Unlocking the Angle Lock

Angle locks are common with Dewalt Saws, and you can locate this lock on the front side of the saw.

The knob keeps the angle locked; press the knob or pin to unlock it, whichever works for your model. This is also used to create different angles to snap the saw into different pre-set angle positions. 

4. Unlocking the Knurled Knob Lock

Miters have this knob lock, which is the easiest to unlock, even for starters. Just twist the knob in a counterclockwise direction, and that’s it. 

5. Unlocking the Bevel

If you want to utilize the bevel function of your miter saw, it’s also necessary to unlock the bevel cut. You will often want to set the titling angle on its desired position to maximize the 45-degree and 40-degree bevel cut options, but if the angle is fixed, you can skip this step.

In setting the titling positioning, slide the stopping pin and push it until the desired angle is set at a certain point.

6. Unlocking the Miter Saw's Base

Saws often come with a head base or table attached to their main structure to provide convenience for their users. This is movable and can be set depending on your preference for cutting wood.

If your saw has a moveable base, unlock it by twisting the knob on the stored position you want. After moving it in a specific direction, twist the knob back to lock the base before working with your saw. 

7. Unlocking Sliding Rails for a Compound Miter Saw

Compound and sliding miter saws have sliding rails which you should unlock as well.

The black lever is usually placed at the end of the saw and is visible because it sticks out. Once you can locate the handle, use this to adjust the location of your guide rail. 

Guide rails are where the saw blade drives in, and on compound miter saws, you can adjust it to make bevel or angled cuts. Note that the black lever is unique to Dewalt models.  Usually, for other brands, the saw uses a latch and a knob when adjusting the guide rail.

Then, locate the small black button, which functions as a release to the locking mechanism of the guide rail. Move the adjustable fence and hold this with your finger as you gradually adjust the angle of your cut.

Extra Tips and Tricks to Know

  1. Unplug the miter saw before you unlock anything on it.
  2. Please do not touch the blade, as it can be very sharp and dangerous. 
  3. Ask for expert help if you get problems unlocking your saw.
  4. Check in with the user manual, as different saws can have particular instructions. 
  5. Wear gloves, safety goggles, ear protection, and extra safety gear like boots, and apply safety precautions when operating with your saw to avoid miter saw injuries.
  6. Apply the right amount of pressure when turning the knob to avoid causing permanent damage to the parts of your miter saw. 
  7. Make time when unlocking, as rushing can cause irreversible damage to the parts of your power tools.

The Locking System of Miter Saw

Angle Lock

Located at the front side of the saw, the angle lock is usually managed by two locks.

Rail Lock

Rail locks aid security on the arm when making certain cuts. It’s located on the blade arm’s base.

Swivel Lock

You’d want to use the swivel lock to connect the points up and down or in a horizontal direction.

Blade Lock

You will find the blade lock on the rear side of the miter saw. Push the head down and pull the pin to secure this lock.

Back Lock

The back lock helps control the blade in an up-and-down direction, and there are different locking systems available in a miter saw [1].

Front Lock

When managing the angles of the cut, the front lock is utilized.

Things To Do After Unlocking the Miter Saw

Unplug the Miter Saw

Keeping your power tools plugged in even after using them can damage your priced possession. Always unplug your tools after use and store the power cord to prevent them from becoming trip hazards. Also, unplugging your tools prevent possible accidental starts. 

Clean it

We highly recommend to always keep your saw clean—dust off the accumulated sawdust debris, which can harden and be corrosive. Sawdust build-up can be difficult to remove. 

Also, the inside of the blade guard is important, so you have to check it. Empty the dust bag so it won’t affect or attack the bag’s material. 

Return the Saw Parts to Proper Storage Positions

Return the adjustable parts to their original position when storing your saw. The table angle adjustment should be in the center position. Lock it in place and adjust the bevel angle to zero. The slider should be in full-back to engage the locking mechanism.

Cover and Protect the Saw

Always keep your power tools covered before storing them. When working on other projects, there’s a tendency for contaminants to drift and settle on your power tool, which is why putting a cloth to wrap your tools on is essential. 

Common Problems on a DeWalt Miter Saw

While DeWalt Miter saws are robust and sturdy enough, it’s still possible for problems to occur, especially after prolonged use. Here are the most common problems you will encounter.

Cracked Edges on Cuts

When a blade is out of tune, it will misalign and cause splinters on the edge of your cuts. Check with your manual on the proper procedure for setting the right alignment back again. 

Burning on the Stock Edges

A dull blade can cause burns or scorch marks to the cutting edge of the material. When it becomes dull, it’s forced to generate more heat when cutting, which then causes the temperature to rise and scorch the wood. 

Wobbling Blade Making Bad Cuts

You don’t want to use a wobbly blade when working with your Dewalt saw. Some of the reasons include the arbor flange can wear down, causing it to wobble. When this happens, replace the arbor flange.

Another thing, blades wobble due to worn-out spindles. Excessive sawdust can accumulate in the tight spaces of your tool, causing excessive wear. 

Gear problems can also cause wobbling, so make occasional drives to the service center for a complete check-up. 

Conclusion

DeWalt miter saws are easy to figure out, but you’ll have to learn the unlocking mechanism thoroughly and follow the steps carefully. 

Some saws have different designs, and there’ll be some adjustments to make. We hope this guide has helped you learn how to unlock DeWalt miter saw with ease.
