Makita GCU08 Chainsaw Review: A Premium 20-Inch Battery Saw With a Break-In Caveat

Introduction

The Makita GCU08 is a 20-inch battery chainsaw positioned as a 50cc gas-equivalent saw, sold as a kit for $1,350. After extensive cutting with it, the picture is mixed in an interesting way: the saw itself feels exceptionally well engineered, with remarkable chain speed and near-perfect ergonomics, but the first batteries’ worth of cutting revealed a cutout issue that gradually improved with use.

This review walks through where the GCU08 shines, where it frustrated, and who should consider it.

Cutting Performance and Torque

Makita claims this is a 50cc-equivalent saw, and some listings go further, saying it cuts 25% faster than a 50cc saw. In practice, the torque right off the trigger is limited. On a 20-inch bar, pushing into larger wood puts the saw right at its cutout threshold, and the first several batteries of cutting produced frequent cutouts.

There was also a bar and chain issue: chips would get inside the bar and bind the chain, making it feel overtight when it was not, and the chain seemed to grab aggressively at certain points, triggering the safety cutoff. Notably, the longer the saw was used, the better it performed, which suggests something in the bar or chain was wearing in. Swapping the bar (about $68, believed to be an Oregon bar) and trying a different chain may resolve this entirely, but that is another $100 on top of the kit.

The saving grace is chain speed: 5,700 feet per minute, which is genuinely impressive and makes the cutting experience excellent when the saw is running freely.

Ergonomics and Controls

This is where the GCU08 earns its price. The handle has a nice rubber overmold, the balance and sizing feel right, and everything about the physical experience of holding and operating the saw is close to perfect. The trigger offers a long variable-speed throw, the chain brake engages precisely, and the rear safety lever is easy to get used to once you acclimate.

The user control panel includes a power button, a battery indicator, and a mode selector that cycles from eco to mid to high. Note that the panel display looks like a fuel meter but is not. Professional touches include alignment lines for felling work, a solid chain brake, and bucking spikes that, while maybe a touch light for their class, are reasonable for a 50cc-class saw.

Oil Capacity and Build Quality

The oil reservoir holds a good volume, the large O-ring on the bottom sealed without any leaking during testing, and the saw generally feels built to a very high standard. The kit is as complete as they come: scratch guard, a quality charger, a full battery, and a file, everything you would expect from a top-of-the-line $1,350 package.

Why You Should Buy It as a Kit

Buy this saw as the kit, not as a bare tool. The large 8Ah gray battery pack with tablet-style cells is what gets the saw up to the rated 50cc-equivalent performance level. Without it, the saw will not deliver what it is designed for.

Who This Saw Is Best For

For a homeowner who wants a top-of-the-line saw that feels professional, is engineered superbly, and handles smaller branches from 4 to 10 inches, this is an easy recommendation. In head-to-head terms, for light branch cutting it was preferred over competing battery saws from other major brands because it is lighter while offering comparable comfort.

For felling large trees, however, the torque shortfall matters. Where a gas 50cc saw, or even a bigger pro gas saw, keeps you in tune with the cut, the GCU08 requires you to stay mindful of not pushing it too far so it does not cut out at a bad moment. If your regular work involves dropping big trees, a gas saw still holds the edge.

Buying Advice

If you already picked one up and were disappointed by the first battery or two, keep going. Something in the bar and chain assembly wears in, and the saw noticeably improves. Expect a possible additional investment of around $100 in a replacement bar and chain to fully tune out the grabbing issue. The core machine, chain speed, trigger, settings, ergonomics, and build quality all rock.

Conclusion

The Makita GCU08 is a wonderful-feeling, professionally engineered battery chainsaw with outstanding chain speed and ergonomics, held back by early cutouts and a bar and chain setup that may need swapping. For homeowners cutting smaller material, it is arguably the best-feeling option in its class. For heavy felling work, look at gas alternatives.
