58 cc Gas Chainsaw, 20 in & 18 in Quick-Switch Bars, 2

The WTHW 58cc Gas Chainsaw is a versatile cutting tool designed for homeowners and property owners handling demanding tree-clearing and maintenance tasks. Powered by a 2-stroke engine, this saw solves the need for multiple machines by supplying two interchangeable guide bars right out of the box, allowing you to adapt quickly to different wood sizes.

Versatility is central to the design thanks to the Quick-Switch bar system. You can mount the 20-inch bar for felling larger trunks and thick fallen trees, or switch to the 18-inch bar for smaller limbing and precision pruning duties. Chain maintenance in the yard is straightforward, as the included scrench tool allows for quick on-site tension adjustments whenever slack develops.

Starting and engine maintenance features focus on keeping field work steady and manageable. The Quick-Start recoil is engineered to fire the engine on the first few pulls even in chilly conditions, while the fuel tank is 30 percent larger for longer continuous operation. To protect internal parts from dust and debris, the saw incorporates a centrifugal air filtration setup alongside an automatic chain oiler.

User handling relies on several integrated safety and comfort mechanisms. An inertial chain brake works alongside a low-kickback chain to manage sudden movement, while a dual-spring anti-vibration system absorbs engine vibrations to reduce hand fatigue. As a trade-off, this is a 2-stroke gas tool requiring regular fuel-oil mixing and chain tensioning, and the listing does not mention specific fluid ounce capacities for the tanks or overall weight.

Verdict: The WTHW 58cc Chainsaw is well suited for property owners who need a flexible gas saw capable of tackling both large tree takedowns and smaller pruning chores with its two included bar sizes.

• Engine Type: 58cc 2-stroke gas engine
• Included Bar Sizes: 20 inches and 18 inches
• 20-Inch Chain Pitch: 0.325P
• 20-Inch Chain Gauge: 0.058G
• 20-Inch Drive Links: 76DL
• 18-Inch Chain Pitch: 0.325P
• 18-Inch Chain Gauge: 0.058G
• 18-Inch Drive Links: 72DL
• Included Tool: Scrench for chain tensioning

A great fit if you:

• Need to tackle both heavy tree felling and general pruning using a single saw.
• Prefer the power and continuous field runtime of a 58cc 2-stroke gas engine.
• Require a reliable pull-start mechanism designed to fire up in cold weather.
• Want built-in anti-vibration and low-kickback safety features for extended yard work.

Consider something else if you:

• Prefer a battery or corded electric saw that avoids 2-stroke oil and gas mixing.
• Want a compact, lightweight tool strictly dedicated to light branch trimming.

What chain sizes are compatible with each bar?
The 20-inch bar uses a chain with a 0.325P pitch, 0.058G gauge, and 76 drive links. The 18-inch bar uses a 0.325P pitch, 0.058G gauge, and 72 drive links.

How do you adjust the chain tension on this chainsaw?
Chain tensioning can be done on-site using the scrench tool included with the saw.

What safety features are built into the saw?
The tool includes an inertial chain brake, a low-kickback chain design, and a dual-spring anti-vibration system to help maintain control and reduce strain.

Does the chainsaw require manual bar oiling?
No, it is equipped with an automatic oiler that continuously lubricates the cutting system during operation.
