What to consider when choosing a gas chainsaw
Motor power
Most chainsaw motors are two-cycle (or two-stroke) motors. Instead of having engine oil in a sump (which would add weight and make it cumbersome to carry around), you mix a small amount of two-cycle oil with the gas. Common ratios are 40:1 and 50:1, but you should always check your chainsaw operating manual to be sure.
在气链电动机中，功率由两个数字表示。马力（HP）测量发动机的功率量，而立方厘米（CC）测量发动机的体积和/或尺寸。您不太可能找到30或75立方厘米以上的气电锯。使用30 cc至40 cc发动机的机器通常被视为消费级电锯，这是您用于一般修剪，院子维护和风暴清除的那种机器。这样的电动机通常会产生约1.5至2马力的功率。
If you step up to the 40 to 60 cubic centimeter range, you’ll find gas chainsaws that are often referred to as “ranch” or “farm” chainsaws. Producing somewhere between 2 and 4 horsepower, these tools can handle a heavier workload. Most individuals, even those with substantial properties, would never need anything more powerful than this.
Chainsaws with motors above 60 cubic centimeters can produce anywhere from 4 to 8 horsepower. These are specialist tools for serious professionals. In fact, many are so big that they're only used for tree felling.
Starting
长期以来，燃气链的开始一直很困难。但是，由于电子点火开关，自动窒息，吹气和其他功能，当今的气电锯要容易得多。
The key is to follow the starting procedure as explained in the owner's manual. Many times when people complain of troubles, it's because they tried to start a chainsaw using a method they used years ago — but on a new machine. If you read the manual and follow the instructions carefully, starting a gas chainsaw shouldn’t present any problems.
Chainsaw bar
The blade that the cutting chain runs around is called the bar. Different bar lengths offer different cutting capacities. Therefore, a chainsaw’s bar length gives an indication of its intended use, but it is not a direct correlation.
Using the right technique, a chainsaw with a 12-inch bar is theoretically capable of cutting down a tree nearly 24 inches in diameter. But that isn’t likely in practice. The motor on a 12-inch gas chainsaw just isn't going to provide enough power for that.
The following is a better guide to general chainsaw performance. For chainsaws that overlap these parameters look carefully at why a particular motor/bar combination has been chosen.
12 to 14 inches:This size bar is generally matched to an engine in the 30 to 40 cubic centimeter range. You end up with a tool that's relatively light and easy to manage, a tool that’s perfect for clearing overgrown areas, pruning, lopping and cutting logs. It's capable of felling a modest size tree on occasion, but it isn’t the machine for doing that regularly.
16 to 20 inches:This bar might be paired with a 40 to 60 cubic centimeter motor, though the latter is unusual. While it's easy to think of this kind of chainsaw as “medium” or “average,” there's no way that should be interpreted as derogatory. These are powerful, flexible tools that can do pretty much everything a small chainsaw can do, but they have the capacity to work hard all day if needed.
20 inches and more:这些酒吧可在专业级的电锯中找到，这是长时间重型登录的大型工具。这些汽油驱动的巨人需要高昂的价格和高水平的技能，以充分利用它们。对于大多数人来说，一个20英寸或更大的酒吧只会过度杀伤。
Weight
The heaviest component on a gas chainsaw is the engine. More power means more weight. If you’re fairly fit, a heavier chainsaw shouldn’t be a problem, but most people are concerned about user comfort and fatigue, and rightly so. And there's no point in buying a heavy chainsaw if you don't need one.
锯用于轻型和中型工作倾向于魏gh between 12 and 14 pounds, while larger tools with bulkier engines can weigh 16 or more pounds. However, the inclusion of lightweight plastic components, variable bar lengths and advances in engine technology can significantly reduce the heft of power saws. Consider how much weight you’re comfortable working with, and keep in mind that a full tank of fuel will increase it further.
其他要考虑的功能
Automatic chain oiler:If the chain isn't lubricated properly, it will overheat and stretch, leading to poor cutting performance and shortened life. An automatic chain oiler is a definite bonus.
Tool-free adjuster:The easier it is to adjust the blade the better. Many chainsaws have a tool-free adjuster that is fast and simple.
链刹车：A chain brake is an excellentsafety featurethat is usually incorporated in a guard for the front handle. Push it forward and it prevents the chain from rotating when the engine is running. Pull it back and the chainsaw works normally.
Blade cover:All gas chainsaws should come with a blade cover. A carrying case is a bonus.
CARB-compliant motor:In certain states, it's illegal to use a gas chainsaw with a motor that isn't CARB-compliant. Check local regulations before buying.
Expert Tip
Avoid mixing oil and gas in a driveway or on concrete as spills of oil and gas will cause stains.

Tips for using a gas chainsaw safely
While chainsaws aren’t the scary tools they're often made out to be, there's obviously an inherent danger in something with the power to rip through trees and branches. Sensible precautions will help keep you safe.
- Practice good safety procedures.Wear work gloves, ear protection, face shield and sturdyfootwearwhen using a chainsaw. Never operate a chainsaw when you’re tired or unwell. Make sure your body is properly balanced and your footing firm. Always work in front of you; never twist to the side as you work. Never overreach with your chainsaw, and never cut above shoulder height. Keep children and pets out of the work area. And beware of fuel spills that could start a fire.
- Know how to use your chainsaw.Get comfortable with the machine. Make sure you understand how to turn it off quickly. Start the chainsaw on the ground. On most gas chainsaws, the rear handle is designed so you can put your foot in there to keep it steady. If you've never used a chainsaw before, start on small branches and work your way up. Kickback is the most common problem when sawing. Avoid cutting with the tip of the bar. Never undercut. Never make adjustments to your chainsaw while the engine is running.
- Maintain your chainsaw.Make sure the chain is properly adjusted and replace it if it’s worn. Check the blade regularly and sharpen it as needed. Poor chainsaw performance is often a result of a badly adjusted or blunt blade. If your chainsaw is smoking or choking, check that the air-intake slots are not blocked by sawdust or debris. Don't be cheap when it comes to replacement blades. A high-quality replacement can be like having a whole new chainsaw.
- Use the right tool for the job.如果您要做的大部分是林地管理很少需要砍伐的树木，请考虑使用一条小型的，顶部的气电锯。这些非常紧凑的工具具有足够的力量。

FAQ
问：一个好的气电锯需要多少？
答：有一些非常便宜的气电锯，我们建议您谨慎。低质量的电锯可能无法应对它所需的严格性，而组件故障可能会带来严重的后果。许多高质量的气电锯，电动机为30至50立方厘米，而12至20英寸的杠铃售价为200至250美元。专业水平的气电锯的价格为450至950美元。如您所见，它们的价格大幅上涨。
Q. How will I know when to sharpen my chainsaw blade?
A.The manufacturer will probably suggest a time frame, in working hours, as a guide for sharpening the blade. But if you don't use your saw often, it's tough to keep track of the number of hours worked. Don't worry. You'll know anyway when the chain fails to cut efficiently or stalls or jams. You'll get fine dust or sludge instead of the sawdust you expect. In extreme cases, the saw will burn the wood where it's rubbing instead of cutting.
问：如何锐化电锯刀片？
A.You can sharpen a blade with a round file specifically designed for the purpose. It might take a bit of practice to get the angle right. Round files cost very little, and for a bit more you can buy a jig that holds the blade and file at the proper angle.
Easier still is a mechanical sharpener. Several models are available. Alternatively, you could find a local garden center or hardware store that offers a sharpening service. They'll do it for you for a few dollars.
Q. Can I buy a replacement chain from a brand other than the manufacturer of my chainsaw?
A.You can purchase a replacement chain from another信誉良好的电锯品牌, but we advise against buying cheap ones if you’re just trying to save some money. You should always buy high-quality chain replacements from reputable makers. They stay sharp longer, last longer and can improve the performance of your chainsaw.
