Makita 79 cc Chain Saw, Power Head Only

The Makita EA7900PRZ1 chainsaw, with its robust 79cc engine and myriad advanced features, is a tool that stands out in the world of professional-grade chainsaws. Having spent ample time putting this powerhouse through its paces, I can attest to its remarkable capabilities and a few quirks that users should be aware of.

Unboxing and Initial Impressions

Straight out of the box, the Makita EA7900PRZ1 impresses with its solid build and thoughtful design. Weighing in at just 14.7 pounds without the bar and chain, it strikes a balance between power and portability. The lightweight design is complemented by an advanced vibration dampening system, making extended use far less fatiguing than one might expect from such a powerful machine.

Getting Started

The chainsaw features an automatic half-throttle lock and a decompression valve designed to make starting the engine easier. However, my initial experience was mixed. Despite following the start-up procedure, I found it challenging to get the saw running smoothly at first. It required some tweaking—specifically adjusting the high and low screws to prevent flooding and resetting the coil gap to ensure a strong spark.

Once these adjustments were made, the saw roared to life, revealing its true potential. It's worth mentioning that these initial setup tasks may pose a challenge for those less experienced with chainsaws. However, for seasoned users, these tweaks are relatively minor inconveniences.

Performance and Power

Once properly tuned, the Makita EA7900PRZ1 is a beast. The 5.7 horsepower engine (4.3 kW) offers more than enough power to tackle even the toughest jobs. I tested it with a 28-inch Tsumura light bar and a 3/8 .050 full chisel chain, making short work of large white oak logs. The saw's performance is best described as relentless, effortlessly zipping through thick rounds like a hot knife through butter.

The fully electronic ignition system ensures optimized performance, and the saw's maximum engine speed of 12,800 RPM keeps the chain spinning at a blistering pace. Whether you're felling trees or bucking large logs, this chainsaw is up to the task.

Ease of Use

One of the standout features of the Makita EA7900PRZ1 is its user-friendly design. The lateral chain tensioning system allows for quick and easy adjustments, which is a significant time-saver in the field. The chain compartment is designed for easy cleaning, and the heavy-duty air filter system enhances durability and reduces maintenance frequency.

For those working in colder climates, the configurable slide-out baffle for cold weather operation is a thoughtful addition. It ensures that the chainsaw performs reliably even in less-than-ideal conditions.

Safety Features

Safety is paramount when working with powerful tools, and Makita has equipped this chainsaw with several important safety features. The two-point inertia/mechanical chain brake is particularly noteworthy, providing an extra layer of protection in the event of a kickback. Additionally, the decompression valve reduces starting effort, making it easier to control the saw right from the get-go.

Durability and Build Quality

The build quality of the Makita EA7900PRZ1 is exceptional. It feels rugged and durable, capable of withstanding the rigors of professional use. The heavy-duty air filter system contributes to the saw's longevity by keeping debris out of the engine, while the advanced vibration dampening system minimizes wear and tear on both the tool and the user.

Final Thoughts

The Makita EA7900PRZ1 is a high-performance chainsaw that delivers on its promises. It combines power, durability, and user-friendly features in a package that's suitable for professional loggers and serious enthusiasts alike. The initial setup might be a bit daunting for those without experience, but once dialed in, the saw's performance is nothing short of outstanding.

Recommendation

Would I recommend the Makita EA7900PRZ1? Absolutely, but with a caveat. This chainsaw is best suited for those who have some experience with tuning and maintaining high-performance saws. If you're a homeowner looking for a simple, easy-to-use chainsaw for occasional yard work, this might not be the best fit. However, if you need a reliable, powerful tool for demanding jobs and don't mind a bit of initial setup, the Makita EA7900PRZ1 is an excellent choice.

In summary, the Makita EA7900PRZ1 is a professional-grade chainsaw that excels in performance and durability. It's a tool that, once properly tuned, will handle the toughest tasks with ease and reliability. For those who know their way around a chainsaw, this is a tool worth investing in.
