by The chainsaw is an indispensable power tool that is used worldwide for cutting wood. Whether you need to fell trees, trim branches, or cut firewood, chainsaws make quick work of all kinds of woodcutting tasks. In this article, we will explore the history and evolution of chainsaws, types of chainsaws available, key features to consider when selecting a chainsaw, proper use and safety tips.
History and Evolution
Chainsaws were originally developed in the late 18th century during the timber boom. One of the earliest versions of a chainsaw was created in 1820 by Benjamin Franklin for cutting logs into boards. However, it wasn’t until around 1926 that the modern chainsaw began to take shape. Norwegian inventor Andreas Bjurman created a prototype powered saw that incorporated a motor attached to a chain mechanism for cutting.
In the 1930s and 1940s, chainsaw technology advanced significantly. The gasoline engine replaced electric motors, allowing for cordless operation. American company McCulloch Power Tools introduced the first gasoline-powered chainsaw in 1948. Meanwhile, rivals Stihl and Dolmar developed chainsaws with anti-kickback accessories and guard plates for increased safety.
By the 1960s, Chainsaws were light enough for one person to operate easily and were widely used for lumber cutting. Major technological improvements in the 1980s included reduced emissions engines and automatic oiling systems to extend bar and chain life. Today’s chainsaws feature electronic ignition systems, improved anti-vibration systems, laser-guided chain tensioning and other advanced technologies.
Types of Chainsaws
Within the chainsaw product category, there are different types to suit various applications and experience levels:
– Gas powered chainsaws: These are the most common type and come equipped with gasoline engines ranging from 30-120cc. They provide high power output suitable for professional forestry and landscaping work.
– Electric chainsaws: Battery-powered chainsaws are cordless for freedom of movement. While lower in power, they are easier to use and don’t emit exhaust fumes. Ideal for homeowners and occasional use.
– Arborist chainsaws: Slightly smaller and lighter saws specialized for tree trimming work. Features include reduced vibration, improved maneuverability.
– Mini chainsaws: Ultra-compact saws under 10 inches weighing 5 lbs or less. Best for light-duty tasks like pruning branches or cutting small logs.
– Farm & Ranch chainsaws: Heavy-duty saws suited for clearing larger acreage with enhanced power, durability and fuel tank capacity.
Factors to Consider when Choosing a Chainsaw
There are important factors to evaluate when selecting the right chainsaw for your needs:
– Power – Evaluate engine size (CCs), cutting diameter and saw weight specifications. Need higher power ratings for felling large trees.
– Bar length – Longer bars cut faster but are bulkier to handle. Choose bar length based on average cutting tasks.
– Vibration dampening – Reduces user fatigue. Rubberized and cushioned components absorb vibration.
– Safety features – Kickback brakes, chain brakes, tip guards and protective chaps are strongly recommended.
– Maneuverability – Saws with low weight-to-power ratio are easiest to use in tight spaces and for overhead cutting.
– Fuel and maintenance costs – Two-stroke saws have cheaper fuel but higher emissions. Weigh oil usage versus fuel efficiency needs.
– Warranty – Extensive coverage gives peace of mind, especially for professional grade saws put to heavy use.
Using Chainsaws Safely
Chainsaws are productive tools when used properly but also inherently dangerous if mishandled. Always follow the basic safety rules:
– Wear full protective equipment including helmet, ear protectors, impact-resistant chaps and boots with cut-resistant soles.
– Learn and practice kickback prevention techniques like positioning saw at an angle, never cutting with upper quadrant of bar.
– Clear area of trip hazards and be aware of swing zone when making cuts. Never cut above shoulder height.
– Carry saw with engine stopped, bar protected by scabbard when moving around job site.
– Maintain control at all times by gripping saw firmly with both hands during operation.
– Use the right saw for each task based on engine power, bar length and application needs.
– Always allow saw components to cool before refueling and never operate near explosive fuels or fumes.
With the proper saw for your application, protective gear and safe handling practices, chainsaws are an invaluable tool for woodcutting tasks. Their evolution over decades has made them more efficient and user-friendly, a cornerstone of landscaping, farming, forestry and other outdoor industries worldwide. When treated with respect, chainsaws can deliver years of reliable service.
