How to Change Blade on Ryobi Miter Saw – 10 Easy Steps Guide

A Miter Saw or most commonly known as the ‘chop saw’ or ‘drop saw’, has been present since the 1970s, and is a very essential and basic tool used by many construction workers, woodworkers, and carpenters. It allows them to make a variety of accurate angled cuts or trims, and this, in short, is the sole purpose of a Miter Saw.

Over time, the development of this machine has allowed it to make cuts or trims at a vast range of angles, making it very useful to many workers, especially woodworkers. Some basic application of this fine machine includes crown moulding, door frames, window casings, trimming of wood, and much more.

But only having a Miter Saw isn’t enough. Knowledge of how to replace its blade is also very vital, and a worker should know how to do it him/herself. Following is a DIY step by step guide on how to change a Miter Saw blade.

During the age of time, many variations have been introduced in the Miter Saw, though the steps to fixing a new Miter Saw blade are very similar for all the variations present. Here we’ll be discussing the Ryobi Miter Saw blade change.

But before knowing how to change a Miter Saw blade, we first need to know the components of a Miter Saw and what their respective functions are so that the user knows what he/she is doing while withdrawing and restoring a Miter Saw blade, making it easy for beginners as well.

Components of a Ryobi Miter Saw

The components mentioned in the diagram are a basic setup of most Miter Saws. Some may have extra parts, but the features listed below are quite common in a lot of the Miter Saws.

As mentioned earlier, to have a better understanding of a Miter Saw and to perform any technical action on them it is very important to know the components and therefore know what they are used for, so that even a beginner can perform well.

Handle/Power Switch

The handle is used to lift or bring down the blade towards the object that is to be crosscut or trimmed. The handle has the power button integrated, which gives the user control over the blade.

Not to confuse this with the main power supply, as we’ll need to know the difference between the latter and former for replacing the blade of the Ryobi Miter Saw.

The power switch, when pressed allows the revolving of the blade, and when let go of, stops the revolving, leaving the blade to come to a halt.

Blade Guard (Cover)

The blade guard envelopes around the blade, creating a barrier between the user and the blade, protecting the operator from any harm during the cutting of objects.

The top half of the guard is connected to a hinge, making it completely stationary, while the bottom half is moveable, and can be retracted to withdraw the old blade, and replace it with a new Miter Saw blade.

Due to the lower half being connected to a hinge, the lower part of the guard automatically swings open as it is lowered down to cut the piece of object.

Table

The table is part of the Miter Saw on which the object to be cut is placed on top. It’s a solid and balanced surface, providing support to the object while it is being cut, minimizing any risk of movement of the object.

It also is connected to the Saw, providing stability and support to the Saw, completing the whole machine within itself. In the table is present a slot, which allows the blade to move into while cutting or trimming any object.

Fence

The fence is attached to the table perpendicularly, to which the object is placed to provide even more stability, accuracy, and precision for cutting. The more stability is given to the object, the better it can be measured and cut or trimmed into, providing accurate results.

Vise

A vise grip is a component mostly common present on Miter Saw’s, either on both sides or at least one. The purpose served by the vise is to provide stability to the Saw whilst it is being lowered for the cutting, or it can also be used to hold longer objects in place while they are being worked.

Blade

The cutting or trimming action of the Saw is done by the blade. A Ryobi Miter Saw blade size is usually 10 inches. There are different sizes of blades present.

Regular sizes used in most Miter Saw blades are 7-1/2 inches, 8-1/2 inches, 10 inches, and 12 inches. The steps for changing a Ryobi Miter Saw blade are pretty much the same for all sizes.

Scale

The Miter saw’s scale is used to show the angle you are cutting at when making any degree of cuts. As the Saw is turned, the scale will also rotate with it.

An indicator is built into the table that points to what degree you are requiring. For a compound saw capable of cutting bevels, an additional scale will be present on the Saw’s arm that indicates the degree it’s angled at.

Miter Lock Adjustment

The Miter adjustment screw is used to angle the saw side to side, depending on the angle that you want to cut the object within. It is unscrewed; a lever is pulled at the bottom and can be moved side to side and hence rotating the Miter saw horizontally.

This action allows the Saw to perform not only straight cuts but also cuts at an angle. If it’s a Compound Saw, then the Saw can also be adjusted at a vertical angle.

Dust Port/ Collector

A component present on most Miter saws. This component is used to collect all the dust that is made during the cutting of an object. It allows the environment to stay clean, as well as the machine itself, by minimizing the dust settling on the Miter Saw.

Table Extension/Stabilizer

These are used to stable the Ryobi Miter Saw on the surface, and also allow larger objects to be placed for cutting or trimming.

The main asset of the Ryobi Miter Saw is its blade. If the blade is unable to cut, then there’s no point in using the Ryobi Miter Saw at all. Here are the main reasons that urge the need to change and replace the blade on the Ryobi Miter Saw:

  • The blade has become dull, the teeth are not sharp, missing, or have broken off. Another indicator is the blade does not cut as smoothly and gets stuck while cutting/trimming. You’ll then know that it is time for a new blade replacement.
  • The object requires a different blade to cut or trim it properly. A Ryobi Miter Saw although, is mostly used to cut wood, can also be used to cut a variety of materials by changing the blade and its respective size.
  • Different blades are used for different cuts. Not all blades are designed to cut the same thickness of the wood. For other types and thicknesses of wood, different blades are also required accordingly.

Precautions To Be Taken Prior Replacing The Blade

Ensure you are wearing safety gloves and safety goggles as the blade can be sharp enough to cause a cut in the skin. Also, there is a chance of breakage of the blade, and small debris can enter the eyes, so ensure to wear safety gloves and safety goggles at all times during this process.

Secondly, before doing any operation on the Ryobi Miter Saw, make sure the main power supply is turned off, and the blade is stationary.

Necessary Tools Required Ensuring Easy Replacement Of Saw Blade

To replace the Ryobi miter saw blade, you should have these things available:

  • Philips Screwdriver
  • 5mm and 100mm hex key
  • Machine oil
  • Safety equipment
  • Combination square

Apart from this, a first aid kit should be present nearby in case any accident happens during the replacement of the blade on the Ryobi Saw Miter.

Step 1. Ensure All Safety Precautions

As mentioned up above in the precautions section, make sure to wear all safety wear,

Step 2. Disconnect The Power Supply

On top priority, make sure that the main power supply is turned off, and the blade is stationary. After 10-15 seconds of power turned off, it is then advisable to touch the machine.

Step 3. Retract Pin And Lift The Blade Arm

If the blade arm is down, gently push on it to loosen the lock pin, pull out the lock pin, and you are free to lift the blade arm, making it easy to replace Ryobi Miter saw blade

Step 4. Loosen Guard Cover Screw And Life The Cover

You’ll first want to take the guard cover out of the way to expose the blade bolt, which we’ll need to be told for the next step. For that, you’ll have to loosen the screw which is present near the centre of the guard cover. Loosen it slightly so that the hinge attached to it can be released.

Do not unscrew it completely. Once done, retract the hinge from the screw, and push the guard cover up and out of the way, leaving room for the blade to be able to be taken out easily.

Step 5. Press The Spindle Lock And Fix The Blade From Rotating

At the opposite side of the blade will be a grey button, which is the Ryobi Miter Saw spindle lock button. With your finger pressed on the spindle lock button, use your other hand to rotate the blade downwards.

After a second or so, the spindle lock button will be locked down by a click sound, and the blade will be fixed, stationary, and unable to rotate. This step is a very vital, or else the Ryobi Miter Saw bolt would not open.

Step 6. Open The Ryobi Miter Saw Blade Bolt

For this, you’ll need a hex key which is provided in the Ryobi Miter Saw accessories or tool kit for the Ryobi Miter Saw blade replacement. Make sure the hex key is fitted in the bolt completely before you untighten it. Now before untightening it, you’ll want first to make sure which way the bolt untightens.

There are two simple methods to identify this. The first way: the direction that the blade rotates in is the same direction that the bolt should untighten. The second way is, on the cover of the blade will an arrow sign on it, whichever way that arrow sign is pointing to, that’ll be the direction for the bolt to untighten.

The blade that has left-handed threads will require the bolt to be turned clockwise so that it untightens. Be sure not to turn the hex key the wrong way or else you might end up stripping the bolt, making it very hard to open.

Step 7. Withdraw The Blade

When the bolt is untightened, remove the outer washer, and be sure not to remove the inner washer. Lift the blade from the spindle and pull it out gently. Take your new Ryobi Miter Saw blade, and replace the old one with the new one by fixing it on the spindle and putting it in place.

Be sure to wipe some motor oil first on the inner washer before fitting in the new blade and on the out washer before adjusting the outer washer at the points where the outer and inner washer contacts the blade surface.

Step 8. Adjust, Fix And Secure The New Blade

Place the outer washer in place, aligning the flats of the washer and spindle. Relax the spindle lock button by unlocking the rotation motion of the blade, and tighten the blade bolt.

Make sure to tighten it the opposite way of which it was untightened, or simply tighten in the direction that is opposite to the direction of the arrow sign on the Ryobi Miter Saw.

Keep in mind that you don’t want to tighten the bolt too much so that you don’t end up stripping the bolt. Just tighten it enough and not excessively.

Step 9. Place Guard And Guard Cover Down

Place the guard cover down, and the guard down until the hinge meets the screw, and then tighten the screw with your Philips screwdriver. The same goes with this screw too: be cautious only to tighten it enough and not over tighten it.

Step 10. Place Blade Arm Down

Place the blade arm down and insert the lock pin back to where it was so that the blade arm is completely done.

And You’re Done

And you’ve done it; a DIY Ryobi Miter Saw blade replacement.

Warnings To Be Noted

  • Unplug the main power source, and if you have a cordless Ryobi Miter Saw then remove the battery before heading on to changing the blade.
  • Always make sure you know which way the blade bolt needs to be turned to be loosened or tightened. It prevents you from stripping the bolt, avoiding difficulty in opening it.
  • Make sure you always use a brand new hex key.
  • When replacing the old blade with the new blade, make sure the teeth are pointed downwards and not upwards.
  • Be sure to wipe some oil on the inner and outer washers.
  • Do not remove the inner washer, and if it’s unintentionally moved, be sure to place it and fit exactly where it was present before to avoid any causalities.

Problems That Can Arise During Changing Of Blade

If it’s a brand new Ryobi Miter Saw, it is usual that the company may have tightened the bolt more than expected. Apply a little more force while you are opening the bolt to let it loose.

If it’s not a brand new Ryobi Miter Saw, then the chances are that the bolt has been stripped. To solve this, use a Ryobi miter saw blade wrench and open the outer bolt so you can release the blade from the spindle.

The Blade Keeps On Spinning

Press the Ryobi miter saw spindle lock button and move the blade downwards until you hear a click sound indicating that the Ryobi miter saw spindle lock button is locked in place

Gently give it a nudge and lift it off the spindle.

How Do You Know The Blade Has Been Changed Successfully

Lower the blade arm, turn the main supply on after ensuring all bolts and screws are tight and press the power switch for a short amount of time, say 5-6 seconds.

If the blade is normally rotating without any interruptions, then the blade has been changed successfully. If it does not then check all the bolts and screws that they are properly fitted and tightened, and that should solve the issue.
