SOYUS 40V 16-Inch Brushless Cordless Chainsaw with 4.0Ah Battery & Charger — Auto-Oiling, Tool-Free Tension

This cordless chainsaw combines a 40V brushless motor with a 4.0Ah lithium-ion battery, a 16-inch bar, and a 300ml auto-oiling reservoir to give homeowners and small-landscape pros a convenient, quieter alternative to gas saws. It reaches high chain speeds and RPM for efficient cutting while reducing routine maintenance thanks to the brushless motor and self-lubrication system. The package includes the battery and charger so you can get to work right away.

How powerful is the SOYUS 40V chainsaw and what can it cut?

The brushless motor and 4.0Ah battery produce crisp, steady power with chain speeds up to 26 ft/s and more than 4,000 RPM, letting the saw slice through branches and logs with fewer passes. It’s designed for general yard work, pruning, storm cleanup, and cutting logs for firewood — not continuous commercial timber harvesting.

• 16-inch bar suitable for limbs, medium trunks, and firewood.
• Chain speed 26 ft/s for efficient bite and reduced stalling.
• Capable of cutting wood up to roughly 20" thick in staged cuts.
• Brushless motor for longer life and steady torque under load.

What safety and convenience features does it include?

SOYUS built multiple safeguards and user-friendly touches into the saw. A dual-switch start system prevents accidental startups, while tool-free chain tensioning and a transparent oil window simplify setup and maintenance without reaching for extra tools.

• Dual-switch activation requires two inputs to start the chain.
• Tool-free chain tensioning for quick adjustments on the job.
• 300ml oil tank with sight window for clear lubrication checks.
• Reduced vibration and noise compared with many gas models.

How does the auto-oiling and maintenance work?

The built-in auto-oiling system feeds lubricant to the chain during operation, keeping the bar and chain cooler and extending component life. The transparent oil reservoir makes it easy to monitor oil level, and the brushless motor lowers routine service needs.

• Automatic lubrication during cutting to reduce wear.
• Transparent oil window for fast visual checks.
• Brushless motor design minimizes brush replacement and vibration.
• Included battery and charger to eliminate accessory searching.

Who is this for: The SOYUS 40V 16-Inch Brushless Cordless Chainsaw is ideal for homeowners, gardeners, and light contractors who need a reliable, quieter alternative to gas chain saws for pruning, storm cleanup, and firewood preparation. It’s for users who value straightforward safety controls, low maintenance, and cordless convenience rather than heavy, continuous commercial milling.
