What is the difference between chainsaws

When it comes to higher end chainsaws, the key metric is its power-to-weight ratio. When you compare these two factors power and weight on the professional grade C-M, you get a power-to-weight ratio of. Farming saws tend to use materials like polycarbonate clamshell frames to protect the workings. Forestry chainsaws are built with a Magnesium side-cover, frame and a built-in crankshaft to reduce weight.

The STIHL C-M also has an electronic component which monitors the fuel levels, which optimises the quality of the fuel, temperature, air pressure, etc. The pro-level chainsaw also has an easy-release cover for the air filter so that you can easily clean it.

Their fast chain speed means less pressure is required from the user to make clean cuts, compared with some underpowered electric models, making them the best bet for heavy-duty work, such as downing large limbs and trees. But most are heavier and noisier than the electric versions. Like all gas-powered tools, gas chainsaws produce potentially deadly carbon monoxide, so you should never operate one indoors.

Starting one requires several hard yanks on a pull cord. Chain-bar lengths are typically 16 to 18 inches for homeowner saws, longer for pro models. Most electric saws have a plug-in power cord and cost less than gas-powered models. They typically weigh less, and they all start effortlessly: Just plug them in and squeeze the trigger. But their slower sawing speed limits them to lighter-duty chores, such as shaping hedges, or trimming the occasional small tree limb.

Their power cord keeps you tethered to the nearest electrical outlet. These saws free you from a power cord. They cost about the same as gas saws, and our most recent tests show that their performance can be as good as—and sometimes better than—that of a gas model.

Run time is determined by the voltage and amp-hour rating of the battery, but expect about 30 to 40 minutes of semi-continuous cutting on a single charge, and about 60 minutes to recharge the battery. For reference, the best battery saw in our ratings cut through a inch-thick oak beam times on a single charge. These saws pack enough power to cut large tree limbs and even small trees. If you have other battery-powered outdoor gear, you should consider buying a chainsaw from the same brand—the batteries are usually interchangeable.

If using a chainsaw strikes fear in your heart but you still need to cut through the occasional small limb, consider a light-duty power lopper. The cutting apparatus is mounted 2 feet away from the hand grips and shielded within a pair of safety jaws.

The lighter one makes it easier to reach a cut, especially if you use the optional extension pole, which adds up to 10 feet of reach for higher limbs. Both models feature a 6-inch retractable blade, making them safe for storage. These formidable tools are involved in more than 27, accidents annually, according to the Consumer Product Safety Commission.

Chainsaws now have safeguards, including an automatic chain brake, that are designed to reduce the hazard of kickbacks. Dress Smart Start with snug-fitting clothing and sturdy work boots, preferably steel-toed.

Shield your legs with cut-resistant chaps and the backs of your hands with protective gloves, and wear a helmet with a face shield. Get a Grip and Stay Grounded Grip gas-powered saws firmly when pull-starting and keep the saw on the ground; most handles include a spot for securing the saw with one foot while pulling the starter cord.

Never saw while on a ladder or use the saw above shoulder height. If you must cut above shoulder height, use an electric lopper, whose encased cutting jaw makes it safer to use than a chainsaw, or hire a pro.

And never saw using the tip of the chain and bar, where kickback can occur. Maintenance Is Key Upkeep is also an important factor in chainsaw safety.

Never run a gasoline-powered tool indoors or in any enclosed space. Chainsaws are simple tools, essentially comprising an engine or a motor, a handle, and an oblong metal piece called the bar that guides the cutting chain. There are a lot of safety features, and the more a model has the better. We assess those features and work them into our safety rating for every model we test. Here are the crucial safety features to look for on any saw. Extra guard links and a less aggressive cutting profile help keep the chain from taking too large a bite, which can cause kickback.

Most chainsaws also have a bar with a narrow tip or nose to limit the cutting area that generates the most kickback. This feature stops the chain almost instantly when the front hand guard is pushed forward or if the chainsaw kicks back. Most gas-powered chainsaws and many electrics now have one. This metal extension beneath the guide bar helps keep a thrown chain from flying back toward the user.

Most models have it, a plus, particularly if the chain is too loose because of improper tensioning and other maintenance.

Most chainsaws now include a separate palm switch that must be pressed before the throttle trigger engages. With your own chainsaw, you no longer have to pull out the axe and get swinging, you can simply split your wood with the power of an electric or gas chainsaw.

Your chainsaw can help with that too! Carefully sculpt foliage around your property, trim bushes down to the proper size, and more in just a few minutes. Feeling creative and looking for a focal piece for your living room? Get carving! For those who are particularly artistic, a chainsaw and a log of wood are the perfect easel for expression.

We have a full guide on stump killers here. Despite having a relatively simple purpose, there is a surprising amount of decision-making involved in shopping for a chainsaw.

Choosing how your chainsaw is powered is probably the most important decision to make, as it will cut down your choices drastically. There are 3 primary types of chainsaw, each with their own perks and shortcomings.

They run off of a rechargeable battery — similar to many other tools like cordless drills. These models are also usually more expensive despite boasting less power than gas-powered chainsaws unless you go with a deluxe option but are also quieter because there is no engine roaring.

Unlike its cordless counterpart, this quiet and lightweight choice plugs into an outlet for its power sourcing, allowing you to cut until your arms get tired. It has similar power to low and mid-tier cordless models, but in general it is weaker than a gas model. This is because of the gas engine they are powered by, which can produce more cutting power and power a longer bar length than their electric coutnerparts.

This allows it to cut larger trees more easily. Unfortunately, along with that powerful motor comes a much louder noise and heavier tool. However, they are entirely mobile and allow for perhaps the most versatility in use for the price. This allows for the safest one-pass chopping. This is because the lesser cutting power of electric models is more suited to residential use that includes only the occasional larger cut.

Naturally, the process of cutting through materials is taxing work on your tool. Here are some things you can do to keep your chainsaw in tip-top shape. The sharper the teeth of your chainsaw , the easier it cuts.
