Types Of Mini Chainsaw
There are several types of mini chainsaws available on the market, categorized by their power sources. They include:
- Corded Electric Mini Chainsaws: These chainsaws are powered by electricity and need to be plugged into an outlet. They are typically lightweight and do not produce harmful emissions. However, they require access to a power source and the length of the power cord can limit their range.
- Battery-Powered or Cordless Mini Chainsaws: These are powered by rechargeable batteries, often lithium-ion. Battery-powered chainsaws offer the benefit of portability and can be used anywhere without the need for a power cord. However, their running time is limited by the battery life, and they may not be as powerful as gas or corded electric models.
- Gas-Powered Mini Chainsaws: These are fueled by a mixture of gasoline and oil. Gas chainsaws are typically the most powerful and can run as long as there is fuel. However, they are also the heaviest, noisiest, and produce emissions.
- Pole Mini Chainsaws: These are basically small chainsaws on the end of a pole, and can be powered by any of the above power sources. They’re used for pruning and trimming tree limbs that would otherwise be out of reach.
- Manual or Hand Chainsaws: These are operated by human power. The chainsaw is moved back and forth to cut through branches or logs. They’re lightweight and portable, but require more physical effort to use.
Each type has its pros and cons, and the best choice depends on your specific needs, such as the nature of your work, your physical strength and stamina, access to a power source, and your budget. As always, safety is paramount when using any kind of chainsaw.
Corded Electric Mini Chainsaws
Corded Electric Mini Chainsaws are a type of compact chainsaw that runs on electricity. These tools are generally lighter, quieter, and easier to maintain than their gas-powered counterparts. They are plugged into an electrical outlet using a power cord, which provides a continuous power supply.

Tensioning Mechanism
The cutting chain is regulated to neither bind or loosen from the guide bar. A screw or wheel turns the tensioner. The clutch cover or lateral exhaust tensioner is used.
Lateral tensioners make mounting the clutch cover simpler but make reaching the bar harder. Tensioners via the clutch cover are easy to use but harder to install.
Turning the screw moves a hook in a bar hole, tensioning or loosening the chain. It’s right when it’s hand-movable and not hanging free from the bar. Hold the bar nose up and tighten the bar nuts. Otherwise, the chain may derail.
A “drive link” on the underside of each link locates the chain on the bar, lubricates the bar, and interacts with the engine’s drive sprocket within the saw. A centrifugal clutch pushes the chain along the track when engine speed rises under power, but stops it when engine speed drops to idle.
Over time, chainsaw design has improved, incorporating safety measures. Chain-brake systems, superior chain design, lighter, ergonomic saws, and fatigue-reducing antivibration systems are examples.
As chainsaw carving becomes more popular, manufacturers are manufacturing short, narrow-tipped bars (called “quarter-tipped,” “nickel-tipped,” or “dime-tipped” bars dependent on tip size). Carving-specific chainsaws exist. Echo funds carvings.
