Dolmar Chainsaws: Gas Models Ending? (5 Insider Woodcutting Facts)

Are Dolmar’s gas-powered chainsaws really going away? And what does that mean for you, the woodcutter? Let’s dive deep into the world of Dolmar, chainsaws, and the future of gas-powered woodcutting tools. I’m going to share some insider facts I’ve picked up over years spent in the forests, working with wood, and yes, even wrestling with a few stubborn logs along the way. We’ll explore the possible shift away from gas models, what’s driving it, and what you need to know to make informed decisions about your next chainsaw purchase.

Globally, the wood processing and firewood industry is undergoing a significant transformation. Environmental concerns and tightening regulations are pushing manufacturers towards battery-powered alternatives, but the tried-and-true gas chainsaw still holds its own for many professionals and hobbyists. According to a recent report by the FAO (Food and Agriculture Organization of the United Nations), global firewood consumption remains substantial, especially in developing countries, highlighting the continued importance of efficient wood processing. In North America and Europe, the demand for firewood is driven by both heating needs and recreational uses, like camping and wood-burning stoves. This demand is met by a combination of professional logging operations and individuals processing their own firewood.

The Chainsaw Landscape: Gas vs. Electric

Currently, gas chainsaws account for approximately 60% of the market, but electric models are rapidly gaining ground, with an annual growth rate of around 15%. This shift is fueled by advancements in battery technology that provide increased power and run time. However, gas chainsaws still dominate in heavy-duty applications where raw power and extended operation are essential.

Dolmar Chainsaws: Gas Models Facing the Sunset?

Dolmar, a name synonymous with quality and reliability, has been a player in the chainsaw market for decades. But the winds of change are blowing, and even established brands like Dolmar are having to adapt. Are gas models truly on their way out? Let’s break down the rumors, the facts, and the implications.

The Electric Revolution

The push towards electric chainsaws is undeniable. Stringent emission standards are forcing manufacturers to innovate, and battery technology has come a long way. We’re seeing electric models that rival the power of their gas counterparts, at least for certain applications.

Fact #1: Emission Regulations Are Tightening

Across the globe, environmental regulations are becoming increasingly strict. The European Union, for example, has implemented stringent emission standards that impact the design and production of gas-powered equipment, including chainsaws. North America also has its own set of regulations, enforced by the EPA (Environmental Protection Agency). These regulations limit the amount of pollutants that gas-powered engines can emit, leading to increased manufacturing costs and, ultimately, a push towards cleaner alternatives like electric chainsaws.

• Insight: These regulations don’t just affect manufacturers; they also impact the end-user. In some areas, there may be restrictions on the use of gas-powered equipment during certain times of the year or in specific locations, such as national parks or densely populated residential areas.

Fact #2: Battery Technology Is Improving Rapidly

Remember the first cordless drills? They were weak and the batteries died in minutes. Today, battery technology is a completely different beast. Lithium-ion batteries offer impressive power-to-weight ratios and longer run times. The latest generation of electric chainsaws can now handle tasks that were once exclusively the domain of gas models.

• Data Point: The energy density of lithium-ion batteries has increased by approximately 5-7% annually over the past decade, leading to significant improvements in battery-powered tool performance.

Fact #3: Dolmar Is Investing in Electric

Dolmar, like other major chainsaw manufacturers, is investing heavily in the development of electric models. They recognize the growing demand for cleaner, quieter, and more convenient alternatives to gas-powered equipment. While they haven’t announced a complete phase-out of gas models, the trend is clear: electric is the future.

• Personal Experience: I remember trying out one of Dolmar’s early electric models a few years ago. I was skeptical, but I was pleasantly surprised by its performance. It wasn’t quite as powerful as my trusty gas saw, but it was significantly quieter and much easier to start.

Fact #4: Gas Chainsaw Innovation Isn’t Dead

While the focus is shifting towards electric, gas chainsaw technology is still evolving. Manufacturers are constantly working to improve engine efficiency, reduce emissions, and enhance user comfort. We’re seeing innovations like stratified scavenging engines, which reduce fuel consumption and emissions, and anti-vibration systems that make gas chainsaws more comfortable to use for extended periods.

• Technical Detail: Stratified scavenging engines use a layer of clean air to separate the exhaust gases from the fresh fuel-air mixture, reducing the amount of unburned fuel that escapes into the atmosphere.

Fact #5: Gas Chainsaws Still Have Advantages

Despite the rise of electric, gas chainsaws still hold some key advantages. They offer superior power for heavy-duty tasks, longer run times (especially with the ability to refuel quickly), and greater portability in remote locations where access to electricity is limited.

• Case Study: A professional logger I know, who works in the remote forests of the Pacific Northwest, relies exclusively on gas chainsaws. He needs the power to fell large trees and the ability to work for days without access to charging stations. For him, electric chainsaws simply aren’t a viable option yet.

Making the Right Choice: Gas or Electric?

So, are Dolmar’s gas chainsaws on their way out? The answer is complex. While the future likely leans towards electric, gas models still have a place in the market, especially for demanding applications. The best choice for you depends on your specific needs and circumstances.

Consider These Factors

• Power Requirements: How large are the trees you’ll be cutting? If you’re primarily dealing with small trees and branches, an electric chainsaw might suffice. But for larger trees and heavier tasks, a gas chainsaw is still the preferred option.
• Run Time: How long do you need to run the chainsaw continuously? Electric chainsaws have limited run times, depending on the battery capacity. Gas chainsaws can run for extended periods with the ability to refuel quickly.
• Portability: Will you be working in remote locations where access to electricity is limited? Gas chainsaws offer greater portability in these situations.
• Noise Level: Electric chainsaws are significantly quieter than gas chainsaws. This can be a major advantage in residential areas or other noise-sensitive environments.
• Maintenance: Gas chainsaws require more maintenance than electric chainsaws. You’ll need to change the oil, clean the air filter, and perform other routine tasks to keep them running smoothly. Electric chainsaws require minimal maintenance.
• Cost: Electric chainsaws typically have a higher initial cost than gas chainsaws, but they can be cheaper to operate in the long run, as you won’t need to buy gasoline or oil.

Key Concepts: Understanding Wood and Tools

Before we get into the nitty-gritty of wood processing and firewood preparation, let’s define some key concepts:

• Green Wood vs. Seasoned Wood: Green wood is freshly cut wood that has a high moisture content. Seasoned wood is wood that has been allowed to dry, reducing its moisture content. Seasoned wood burns more efficiently and produces less smoke than green wood.
• BTU (British Thermal Unit): A unit of energy used to measure the heat content of fuel. Different wood species have different BTU ratings, indicating how much heat they produce when burned.
• Cord: A standard unit of measurement for firewood. A cord is a tightly stacked pile of wood measuring 4 feet high, 4 feet wide, and 8 feet long.
• Chainsaw: A portable, mechanical saw powered by a gas engine or electric motor, used for felling trees, limbing branches, and bucking logs.
• Axe: A hand tool used for splitting wood. Axes come in various sizes and weights, depending on the type of wood being split and the user’s strength.
• Splitting Maul: A heavy, axe-like tool designed specifically for splitting logs. Splitting mauls have a wider head and a heavier weight than axes, making them more effective for splitting tough or knotty wood.
• Wedge: A metal or plastic tool used to split logs by driving it into a crack or split. Wedges are often used in conjunction with a sledgehammer.
• Cant Hook: A long-handled tool with a pivoting hook, used for rolling logs. Cant hooks are essential for moving large logs that are too heavy to lift.

Step-by-Step Guide to Felling Trees Safely

Felling a tree is a dangerous task that should only be undertaken by experienced individuals who have been properly trained. If you’re not comfortable felling trees yourself, it’s best to hire a professional arborist.

Safety First:

• Always wear appropriate safety gear, including a hard hat, eye protection, hearing protection, gloves, and chainsaw chaps.
• Inspect the tree for any signs of weakness, such as dead limbs, cracks, or decay.
• Clear the area around the tree of any obstacles, such as branches, rocks, or debris.
• Plan your escape route in advance, ensuring that it’s clear and unobstructed.
• Never fell a tree in windy conditions.

Step 1: Planning the Fell

• Assess the tree’s lean and any natural obstacles that might affect its fall.
• Determine the desired direction of fall, taking into account the tree’s lean, wind direction, and surrounding obstacles.
• Clear the area around the base of the tree of any brush or debris.

Step 2: Making the Notch

• The notch is a wedge-shaped cut that helps to control the direction of fall.
• Make the notch on the side of the tree facing the desired direction of fall.
• The notch should be about one-third of the tree’s diameter.
• The top cut of the notch should be angled downward at about 45 degrees.
• The bottom cut of the notch should be horizontal and meet the top cut.

Step 3: Making the Back Cut

• The back cut is a horizontal cut made on the opposite side of the tree from the notch.
• The back cut should be made slightly higher than the bottom cut of the notch.
• Leave a hinge of uncut wood between the back cut and the notch. The hinge helps to control the fall of the tree and prevents it from kicking back.
• As you make the back cut, watch for signs of the tree starting to fall.
• When the tree starts to fall, shout a warning to alert anyone in the area.

Step 4: Retreating Safely

• Once the tree starts to fall, immediately retreat along your planned escape route.
• Keep your eye on the falling tree and be prepared to dodge any falling branches.
• Do not approach the tree until it has completely fallen and come to rest.

De-Limbing Procedures: A Detailed Guide

Once the tree is on the ground, the next step is to remove the branches, also known as de-limbing.

Safety First:

• Continue to wear appropriate safety gear.
• Be aware of the potential for branches to spring back when cut.
• Work from the base of the tree towards the top.
• Keep your feet firmly planted and maintain a stable stance.

Step 1: Position Yourself Safely

• Stand on the opposite side of the tree from the branch you’re cutting.
• Use the tree trunk as a shield to protect yourself from flying debris.

Step 2: Make the Cut

• Start by cutting the smaller branches.
• For larger branches, make an undercut first to prevent the bark from tearing.
• Then, make a top cut to sever the branch completely.

Step 3: Dispose of the Branches

• Pile the branches in a designated area for later disposal.
• Consider using a wood chipper to turn the branches into mulch.

Splitting Logs: Techniques and Tools

Splitting logs is a necessary step in preparing firewood. It reduces the size of the logs, making them easier to handle and allowing them to dry more quickly.

Safety First:

• Wear appropriate safety gear, including eye protection, gloves, and steel-toed boots.
• Work on a stable surface, such as a chopping block.
• Keep your feet clear of the splitting area.
• Use a splitting maul or axe that is appropriate for the size and type of wood you’re splitting.

Step 1: Choose Your Tool

• For small logs and softwoods, an axe may be sufficient.
• For larger logs and hardwoods, a splitting maul is recommended.
• For particularly tough or knotty logs, a wedge and sledgehammer may be necessary.

Step 2: Position the Log

• Place the log on the chopping block, ensuring that it’s stable and won’t roll.
• Position the log so that any knots or imperfections are facing upwards.

Step 3: Swing and Split

• Grip the splitting maul or axe firmly with both hands.
• Raise the tool overhead, keeping your back straight.
• Swing the tool down forcefully, aiming for the center of the log.
• If the log doesn’t split on the first attempt, repeat the process.

Step 4: Using a Wedge

• If the log is too tough to split with a maul or axe, use a wedge.
• Drive the wedge into a crack or split in the log.
• Use a sledgehammer to drive the wedge further into the log until it splits.

Seasoning Firewood: Achieving Optimal Drying

Seasoning firewood is crucial for efficient burning and reduced smoke. Green wood contains a high moisture content, which makes it difficult to ignite and causes it to burn inefficiently. Seasoned wood, on the other hand, has a lower moisture content, which allows it to burn hotter and cleaner.

Target Moisture Content:

• The ideal moisture content for firewood is between 15% and 20%.
• You can use a moisture meter to check the moisture content of your firewood.

Step 1: Stack the Firewood

• Stack the firewood in a single row, with the logs parallel to each other.
• Elevate the stack off the ground using pallets or boards to allow for air circulation.
• Leave space between the rows to allow for air flow.
• Cover the top of the stack with a tarp to protect the firewood from rain and snow.

Step 2: Choose a Sunny and Windy Location

• Select a location that receives plenty of sunlight and wind.
• Sunlight helps to evaporate moisture from the wood.
• Wind helps to carry away the moisture.

Step 3: Allow Sufficient Drying Time

• The amount of time it takes to season firewood depends on the type of wood, the climate, and the stacking method.
• Generally, it takes at least six months to a year to properly season firewood.
• Hardwoods, such as oak and maple, take longer to season than softwoods, such as pine and fir.

Data Point: Studies have shown that properly seasoned firewood can produce up to 25% more heat than green wood.

Different wood species have different properties that affect their heat output, burning characteristics, and ease of splitting.

• Hardwoods vs. Softwoods: Hardwoods are generally denser and have a higher BTU rating than softwoods. They burn longer and produce more heat. Softwoods ignite more easily but burn faster.
• Oak: A popular choice for firewood due to its high BTU rating and long burning time. Oak can be difficult to split, especially when green.
• Maple: Another excellent choice for firewood, with a high BTU rating and relatively easy splitting.
• Ash: A good all-around firewood, with a moderate BTU rating and easy splitting.
• Birch: A good firewood for kindling, as it ignites easily. Birch has a moderate BTU rating and burns relatively quickly.
• Pine: A softwood that ignites easily but burns quickly. Pine has a lower BTU rating than hardwoods and produces more smoke.
• Cedar: A softwood that has a pleasant aroma when burned. Cedar has a low BTU rating and produces a lot of smoke.

Costs, Budgeting Considerations, and Resource Management

Preparing firewood can be a cost-effective way to heat your home, but it’s important to consider the costs involved and manage your resources effectively.

• Chainsaw Costs: Chainsaws range in price from a few hundred dollars to several thousand dollars, depending on the size, power, and features.
