How to Unlock a Miter Saw: It’s Probably the Transport Lock, Not the Bevel Lock

If your miter saw’s head won’t lift up at all, you’re not looking for a “bevel lock” or “miter lock” – you need to release the transport/carrying lock, a completely separate pin or knob near the hinge that holds the saw head down for storage and carrying. This is the single most common point of confusion with this question: “locked” almost always means the transport lock on a brand-new or just-unboxed saw, not the angle-adjustment locks used during normal cutting.

Two Completely Different Things Called “Locked”

Every sliding or compound miter saw has locks for two unrelated purposes, and mixing them up is why this trips people up:

• Transport/carry lock: a spring-loaded pin or knob near the rear hinge that holds the saw head pressed all the way down against the base, so the saw is compact and safe to carry by its handle. This is almost always what’s locked on a saw fresh out of the box or one that just came out of a truck.
• Bevel lock and miter lock: separate levers/knobs used during normal operation to lock in a specific cutting angle once you’ve set it. These have nothing to do with whether the head can move up and down – they only restrict the tilt (bevel) or the table rotation (miter).

Releasing the Transport Lock, by Brand

The mechanism is similar across brands but the exact motion differs enough to matter:

• DeWalt (most sliding compound models): push down slightly on the handle to take pressure off the pin, then pull the transport lock pin (located near the base of the handle, close to the hinge) outward and rotate it a quarter turn to hold it clear. The head will spring up once released.
• Makita (LS series): push the head down slightly, then pull out the lock pin near the rear of the head and rotate it 90 degrees so it catches in the unlocked position. Some Makita models use a knob you unscrew rather than a spring pin, so check which style yours has before forcing it.
• Bosch (glide and standard compound models): press down on the handle, pull the carrying lock knob (typically near the top-rear of the head assembly), and rotate it to release. Glide-style Bosch saws also have a separate rail lock for the sliding arms – check that one too if the head moves but won’t slide.
• Ryobi and Craftsman: press down on the head, locate the lock pin near the hinge point at the back, pull it out, and turn it about a quarter turn until it stays retracted.

If the pin won’t budge, don’t force it – press down slightly harder on the head first. These pins are spring-loaded and designed to only release cleanly when the head is at the exact bottom of its travel; trying to pull the pin while the head is at any other angle just binds it.

Bevel and Miter Locks: What They Actually Do

Once the transport lock is released and the saw is set up for cutting, the bevel and miter locks come into play every time you change your cutting angle:

• Bevel lock: usually a lever behind the saw head. Loosen it to tilt the blade for a beveled cut, then re-tighten it before cutting – a loose bevel lock is a real safety hazard since the blade can shift mid-cut.
• Miter lock: typically a handle or lever under the front of the table. Loosen it to rotate the table to your angle, then lock it back down. Most saws also have a detent override button that lets you set an angle between the common preset stops (0°, 15°, 22.5°, 30°, 45°).

Safety Checks Before Your First Cut

Once the saw moves freely, don’t cut yet. Confirm the blade guard retracts and springs back on its own, check that both the bevel and miter locks hold firmly once tightened, and make sure the material is clamped or held flat against the fence. If anything about the head’s movement feels gritty or uneven after releasing the transport lock, that’s usually accumulated sawdust in the pivot – a quick brush-out and a drop of light machine oil on the hinge point solves most of it.

Frequently Asked Questions

How do I unlock a miter saw for the first time?

Push down slightly on the saw head to take tension off the transport lock pin, then pull the pin (located near the rear hinge) and rotate it a quarter turn so it stays retracted. This is the lock that ships engaged on nearly every new miter saw and is unrelated to the bevel or miter angle locks.

What safety precautions should I take when unlocking a miter saw?

Keep the saw unplugged while releasing the transport lock, keep your fingers clear of the blade area since the head can spring upward once freed, and don’t force a stuck pin – press the head down further first rather than pulling harder.

Can I use a miter saw without releasing the transport lock?

No. With the transport lock engaged, the head can’t move up and down at all, so the saw physically cannot cut anything. It has to be released before the saw is usable, every time you set it up after moving or storing it.

Bottom Line

If your miter saw “won’t unlock,” it’s almost certainly the transport lock pin near the hinge, not the bevel or miter angle locks. Find that pin, press the head down slightly to release tension, pull and rotate it, and the head will move freely. From there, the bevel and miter locks are the ones you’ll actually use every time you change a cutting angle.
