Who it fits

Key specs explained for you

Engine Displacement: 58 cc

This displacement indicates the engine size and potential power output. A 58 cc two-stroke engine provides substantial torque for cutting through dense wood. You will find this suitable for felling medium-to-large trees or processing thick limbs that smaller units might struggle with. When comparing gas chainsaws, higher displacement generally correlates with faster cutting speeds and the ability to handle tougher material without bogging down.

Bar Length: 20 in & 18 in

The inclusion of both 20-inch and 18-inch bars offers versatility for different tasks. The 20-inch bar is ideal for cutting larger diameter logs or felling trees, while the 18-inch bar allows for better maneuverability when pruning or limbing. This quick-switch system lets you adapt to the job without hauling multiple saws. You benefit from having the right reach for each specific cutting requirement efficiently.

Motor Type: 2-stroke

A two-stroke engine completes a power cycle in two piston strokes. This design is lighter and more powerful than four-stroke engines for the same weight. You get high power-to-weight ratio, which reduces fatigue during extended use. However, you must mix oil with gasoline for proper lubrication. This is a standard power source for professional-grade gas chainsaws requiring maximum performance in outdoor environments.

Weight: 14.5 pounds

This weight reflects the total mass of the chainsaw unit. At 14.5 pounds, the saw is substantial but manageable for most users. It suggests a robust build capable of handling heavy-duty work without being overly burdensome to hold overhead. When comparing similar gas models, this weight indicates a balance between durability and operator comfort, allowing for sustained use during extended yard work or property maintenance sessions.

Design and Build Overview

The listing describes the WTHW 58cc gas chainsaw as a blue unit. It measures 20 inches in length, 16 inches in width, and 10 inches in height. The total weight is 14.5 pounds. These dimensions suggest a tool that fits in standard toolboxes or truck beds. The weight is manageable for one-person operation, though you may need a stable stance for heavy cuts.

The design centers on a 58 cc two-stroke engine. The listing notes a 30% larger fuel tank than standard models. This choice supports longer runtime without frequent refueling. You can use this for all-day projects without stopping as often. The quick-switch system allows you to swap the 20-inch felling bar for the 18-inch limbing bar in seconds. This layout reduces the need to haul multiple saws for different tasks.

Safety and control features are integrated into the build. An inertial chain brake and low-kickback chain are included. A dual-spring anti-vibration system is listed to reduce engine buzz. On-site chain tensioning uses an included scrench. A centrifugal air filter and automatic oiler are specified to protect the engine from dust. These choices aim to keep the tool running reliably in dusty or debris-heavy environments. The finish and materials are not detailed beyond the blue color.

Setup and Everyday Use Guide

Setting up this chainsaw begins with selecting the appropriate bar for your immediate task. The unit includes both a 20-inch felling bar and an 18-inch limbing bar. You can swap between these two options using the quick-switch system. This mechanism allows you to change bars in seconds without needing additional tools. Once the bar is installed, you attach the matching chain. The 20-inch chain has 76 drive links, while the 18-inch version has 72 drive links. Both chains share a 0.325 pitch and 0.058 gauge. You can adjust chain tension quickly using the included scrench. This on-site tensioning feature helps you eliminate delays and keep working efficiently.

Daily operation starts with fueling the saw. The listing notes a fuel tank that is 30% larger than standard models. This larger capacity supports more continuous runtime, which reduces the frequency of refueling stops during long projects. The 58 cc two-stroke engine is designed to fire up reliably with a few pulls, even in cold conditions. This quick-start recoil system minimizes frustration during setup.

While cutting, the automatic oiler lubricates the chain continuously. The pro-grade centrifugal air filter protects the engine from dust and debris, which helps maintain performance and extends tool life. You benefit from a fast-acting inertial chain brake and a low-kickback chain for safety. The dual-spring anti-vibration system reduces engine buzz, helping to lower fatigue during extended use. The gas power source provides the torque needed for dense wood, making this tool suitable for both heavy felling and precision pruning tasks.

Owning This Chainsaw Requires Planning

Owning this gas chainsaw requires planning beyond the purchase. You must source two-stroke fuel mix, as it does not run on pure gasoline. Keep spare chains handy. The listing specifies 0.325 pitch and 0.058 gauge for both included bars. Verify your local bar compatibility if you plan to upgrade later. Maintenance is straightforward but essential. The centrifugal air filter needs regular cleaning to prevent dust buildup. Check the automatic oiler before each use to protect the guide rail. This tool sits outside the Wood Chippers & Shredders category. It handles felling and pruning, not chip processing. Use it for tree removal, then bring in a wood chipper for the resulting debris. This workflow separates cutting from processing. Ensure your workspace has adequate ventilation for exhaust fumes. Store fuel properly to maintain engine health. The quick-switch system reduces downtime between tasks. Plan your project sequence to maximize efficiency. This saw is a specialized cutting tool, not a multi-purpose yard machine.

Check before you buy

• Buy two-stroke fuel mix for the engine.
• Verify 0.325 pitch bar compatibility for upgrades.
• Clean the air filter regularly.
• Check the automatic oiler before use.
