Craftsman Radial Arm Saw Blade Guard Kit: How to Install and Use One Safely

A craftsman radial arm saw blade guard kit is the set of parts that covers the blade, keeps your hands clear of the teeth and directs dust away from your face. This guide walks you through identifying the right kit for your saw, installing it correctly, testing that it moves freely and using it in everyday cuts. Because radial arm saws are among the more hazardous tools in a home shop, a properly fitted guard is one of the most important safety features you can maintain.

What a Blade Guard Kit Includes

Most guard assemblies for Craftsman radial arm saws share a common design, though the exact parts vary by model and production year. Before you buy or install anything, lay out what you have and compare it against your saw’s manual or parts diagram.

• Upper blade guard: the hood that covers the top and rear of the blade and rides on the arm.
• Lower guard or anti-kickback pawls: spring-loaded fingers or a lower shield that prevents the workpiece from being thrown back toward the operator.
• Mounting bracket and hardware: the bracket that attaches the guard to the yoke or arm, plus bolts, washers and a spring or pivot pin.
• Dust port or chute: on many kits, a port that connects to a shop vacuum or dust collector.

Some older kits are missing one or more of these pieces. If parts are missing, check the model number on the saw’s data plate before ordering replacements, since blade diameter and arm length affect the bracket geometry.

Tools and Materials You Will Need

Gather everything before you start. Working with the saw unplugged and the blade stopped prevents accidental starts during assembly.

• Wrenches or sockets that match the guard hardware (commonly metric or standard sizes printed on the parts diagram)
• A hex key set for any set screws in the pivot or spring assembly
• A flat-blade screwdriver and a small cup for holding fasteners
• A combination square and a ruler for alignment checks
• Blue painter’s tape or a marker for marking alignment points
• A soft cloth and degreaser to clean the arm and yoke before mounting
• Clean, sharp blade of the correct diameter for your saw

Step-by-Step: Installing the Guard

Step 1: Unplug the saw and lock the blade

Disconnect the power cord from the outlet. Lock the arm in the rear position and confirm the blade cannot rotate. Remove the blade if you need clearer access to the mounting points, and note the arbor washer orientation before you do.

Step 2: Clean the mounting surfaces

Remove sawdust, resin and old grease from the arm and yoke where the bracket will sit. A clean surface gives the bracket a stable seat and prevents the guard from drifting over time.

Step 3: Attach the bracket loosely

Fit the bracket to the arm using the supplied bolts. Snug them by hand first. Leave them loose enough that you can still shift the bracket a few millimeters, because you will need to adjust its position during alignment.

Step 4: Mount the upper guard

Seat the upper guard onto the bracket and secure its pivot pin or thumbscrew. The guard should cover the top of the blade and extend down to just above the table surface at the front edge, leaving only the cutting portion exposed.

Step 5: Align the guard to the blade

Set the blade to the 90-degree position (square to the fence) and check that the guard sits centered over the blade. Use a combination square against the table and the guard lip to confirm clearance. Aim for a gap of about 1/8 inch or less between the guard and the blade’s upper teeth, and no contact with the blade at any angle you plan to use.

Step 6: Install the lower guard or pawls

Fit the anti-kickback pawls or lower shield according to the manual. The pawls should pivot freely, drop down onto the workpiece under spring tension and return to rest when lifted. If your kit uses a lower guard, check that it does not interfere with the table or fence.

Step 7: Tighten and recheck

Once alignment is correct, tighten all bracket and pivot hardware fully. Recheck clearances, because tightening often shifts parts slightly.

Testing the Guard Before Cutting

A guard that looks correct on the bench can still bind during a cut. Run through these checks with the saw unplugged, then again with the saw plugged in but the blade stopped.

1. Rotate the arm through its full range of motion, including the 45-degree and 90-degree miter positions. The guard should move with the arm without catching on the table, fence or motor housing.
2. Lift and release the pawls by hand. They should spring back to the workpiece position without sticking.
3. Check that the guard does not touch the blade at its highest and lowest travel positions.
4. Confirm the dust port, if present, does not pinch or restrict the hose when the arm travels.
5. Plug the saw in, start the motor briefly and watch the blade and guard from the side. Stop immediately if you see vibration or contact.

Using the Guard During Everyday Cuts

The guard only protects you if it stays in place during the cut. A few habits help.

• Set the guard height so it sits just above the workpiece. Lowering it all the way is rarely necessary and can restrict your view of the cut line.
• Keep your hands at least 6 inches from the blade path. Use a push stick or push block for narrow stock.
• Let the pawls hold the workpiece down before you advance the blade. Do not force a piece past a stalled blade.
• Return the arm to the rear position after each cut and allow the blade to stop completely before lifting the guard.

Common Mistakes to Avoid

• Removing the guard for convenience. Radial arm saws are prone to kickback and blade pull-in. Running without the guard leaves your hands exposed.
• Using a mismatched blade. A blade that is too large or too small for the guard can make it impossible to align correctly.
• Skipping the alignment check after a blade change. Changing blades can shift the arbor position enough to affect guard clearance.
• Tightening bracket bolts before aligning. This locks the guard in a poor position and makes adjustment difficult.
• Ignoring worn pawls. Weak springs or bent pawls reduce their ability to hold stock down. Replace worn parts promptly.
• Letting dust build up on pivots. Sawdust and resin stiffen the guard’s movement. Clean the pivots regularly with a dry brush or compressed air.

Recommended gear

These items support safe installation and use of a radial arm saw guard. Confirm compatibility with your saw model before buying.

• Combination square: gives you a reliable 90-degree reference for checking guard clearance against the blade and table.
• Push sticks and push blocks: keep your hands well away from the blade when cutting narrow stock under the guard.
• Shop vacuum with a dust hose adapter: connects to the guard’s dust port and keeps the cutting area clear of debris that can affect pawl movement.
• Replacement anti-kickback pawls: worn pawls lose their holding force, so a matched replacement set is a practical way to restore function.

FAQ

Can I use a Craftsman radial arm saw without the blade guard?

The manufacturer’s manual and general shop safety guidance both recommend keeping the guard installed during operation. Removing it exposes the blade and increases the risk of kickback and contact injury.

How do I know if my guard kit fits my saw?

Check the model number on the saw’s data plate and compare it against the parts diagram in the owner’s manual. Confirm blade diameter, arm length and bracket style. If you are unsure, contact the manufacturer or a qualified parts supplier with your model number.

How close should the guard be to the blade?

Aim for a clearance of roughly 1/8 inch or less between the guard and the upper blade teeth, with no contact at any arm position you use. Follow the specific tolerance in your manual if it differs.

Why do the anti-kickback pawls not hold my workpiece?

Common causes include worn or weak springs, bent pawls, dust buildup on the pivots, or a pawl set at the wrong height. Clean the pivots, check the springs and adjust or replace the pawls as needed.

Do I need to realign the guard after changing the blade?

Yes. A different blade, or a change in how it seats on the arbor, can shift clearance. Recheck alignment and rotation through the full range of motion after every blade change.

Can the dust port be used with a shop vacuum?

Many guard kits include a dust port designed for a standard shop vacuum hose. Confirm the port diameter matches your hose and that the hose does not restrict arm travel.

What should I do if the guard is damaged?

Stop using the saw until the guard is repaired or replaced. A cracked guard, bent bracket or missing hardware cannot protect you reliably. If you are unsure how to assess damage, a qualified repair technician or the manufacturer can advise you.

Is a guard enough to make the saw safe?

No. A guard is one part of a safe setup. Pair it with proper blade selection, a clean work area, correct stock support, eye and hearing protection, and a full read of the owner’s manual. Anyone new to radial arm saws should consider a hands-on lesson from an experienced woodworker or a local safety course.

Conclusion

A correctly fitted craftsman radial arm saw blade guard kit protects your hands, deflects debris and reduces kickback risk during every cut. Identify your kit’s parts, install the guard with careful alignment, and test its movement before you power up. Check the guard regularly, replace worn pawls and keep the pivots clean so it continues to do its job.
