Ryobi TS1340 compound miter saw Parts

Yes. With the Ryobi TS1340 10-inch compound miter saw, we can cut a 4x4 (dimensional lumber) at 0° miter, and the manual also lists 4x4 capacity at 45° miter. For the safest, cleanest cut, clamp the workpiece and keep hands outside the marked no-hands zone.

What the TS1340 is rated to cut

The TS1340 operator documentation lists these maximum dimensional lumber sizes:

Miter setting	Max dimensional lumber size
0° miter	4 x 4, 2 x 6
45° miter	4 x 4, 2 x 6
45° miter (common limitation)	2 x 4

Use the cut capacity chart in the TS1340 owner's manual as the final word for your exact setup and angle.

How to get a safe, accurate 4x4 cut

• Clamp or bolt the saw to a stable workbench before cutting.
• Use the included work clamp (or an equivalent clamp) to prevent the 4x4 from twisting.
• Hold the 4x4 firmly against the fence; never cut freehand.
• Keep hands at least 3 inches from the blade and outside the no-hands zone markings.
• Let the blade reach full speed before entering the cut; wait for a complete stop before raising the arm.

Why it matters

A 4x4 is thick enough that any movement can pinch the blade, pull the workpiece, or ruin the cut. Proper clamping, correct miter settings, and safe hand placement reduce kickback risk and help the saw deliver a square, repeatable crosscut.

A 10-inch miter saw is the better all-around choice for most DIY and trim work because it’s lighter, easier to move, and uses less expensive blades. A 12-inch miter saw is better when you regularly need maximum cut capacity for wider or taller stock. For the Ryobi TS1340 specifically, it’s a 10-inch compound miter saw, so it’s built around portability and everyday cutting capacity (see the TS1340 operator's manual).

How to choose: capacity vs portability

Use these practical decision points:

• Choose 10-inch when you value easier carrying, smaller footprint, and lower blade cost.
• Choose 12-inch when you frequently cut wider boards, taller baseboard, or larger crown molding.
• Choose 10-inch when most cuts are 1x and 2x trim, flooring transitions, and general home projects.
• Choose 12-inch when you routinely cut larger stock and want more “reach” at common miter angles.
• Choose either size based on the features you need most (compound bevel, positive stops, dust collection, clamp).

Quick comparison

Feature	10-inch miter saw	12-inch miter saw
Typical best use	Trim, DIY, general carpentry	Larger stock, frequent wide cuts
Portability	Easier to move and store	Heavier and bulkier
Blade cost	Typically lower	Typically higher
Cut capacity	Good for most home projects	Better for wide and tall material

What we know about the Ryobi TS1340 (10-inch)

The Ryobi TS1340 is a 10 in. (254 mm) compound miter saw with a 15-amp motor. It’s designed to handle tough cutting jobs while staying in the more portable 10-inch class. The manual also lists common cutting capacity examples at standard settings, including cuts in dimensional lumber such as 4x4 and 2x6 at 0° miter.

Why it matters

Picking the right blade size affects more than just “how wide you can cut”; it also impacts how often you’ll need to flip material, how easy the saw is to transport, and your ongoing cost for replacement blades. If you already own the TS1340, you’re in the 10-inch category, so the best upgrade is usually a higher-quality 10-inch blade matched to your material.

On a Ryobi TS1340 compound miter saw, we never make freehand cuts, never cut pieces too small to clamp, and never cut more than one workpiece at a time. We also avoid materials the saw and blade are not designed for because they increase binding, kickback, and injury risk (see the TS1340 owner's manual).

Cuts and materials to avoid

• Never cut freehand; always hold the workpiece firmly against the fence.
• Never cut tiny pieces you cannot clamp; keep hands out of the “no hands zone” (at least 3 inches from the blade path).
• Never stack workpieces; cut one piece at a time.
• Never hold or bind the free scrap end of a clamped workpiece; the blade can catch it and kick it up.
• Never cut with guards removed or not working properly; check the blade guard before every use.
• Never cut materials outside the saw’s intended use; this model is intended for crosscutting wood and plastic (use the correct blade for the material).

Safe “do this instead” setup checklist

• Clamp or bolt the saw to a stable bench at about hip height.
• Use the fence as a backstop for every cut.
• Use a sharp, clean blade with the correct size and style for the cut.
• Let the blade stop completely before raising it or reaching for offcuts.
• Stand out of line with the blade path and keep solid footing.

Quick guide: OK vs. not OK (typical)

Task or material	Safe on a miter saw?	Better approach
Crosscutting wood	Yes	Clamp long stock, support both ends
Crosscutting plastic	Yes (with correct blade)	Use a blade intended for plastic
Freehand cutting	No	Use fence and clamps
Stacked pieces	No	Cut one piece at a time
Very small parts	No (if not clampable)	Use a stop block and clamp, or a different tool/jig

Why it matters

Most miter saw injuries happen when the workpiece shifts, binds, or gets grabbed by the blade. Following the TS1340 rules (use the fence, clamp the work, keep hands 3 inches away, and avoid freehand or stacked cuts) directly reduces kickback and loss of control.

Finding parts and diagrams

We list replacement parts by model so you can match what you need to your exact saw. If you do not see what you need in the TS1340 parts list, search by model number on Sears PartsDirect.
