Best Cordless Chainsaw

There are many different types of chainsaws available for purchase. You can choose from a manual chain saw, a gas-powered chain saw, an electric chain saw, or a cordless chainsaw. Each one has its own advantages and disadvantages so it’s important to pick the one that best suits your needs.

A manual chainsaw is exactly what it sounds like. There is no power source. You operate it by hand.

While this may seem extremely inconvenient, there are many people who prefer this since it limits their strength and allows them to focus on the task at hand rather than worrying about a learning curve with a new piece of equipment.

One thing to be aware of with a manual chainsaw is that they can be very dangerous to use. If you apply to much pressure or cut through something harder than you thought it might be, the saw can potentially bind up and kick back. Kickback is when the tip of the saw bounces back in the opposite direction of where it was heading, which can lead to serious injury.

The next type of chainsaw is a gas-powered chainsaw. This is definitely the most common and popular type. You can find them in a wide range of sizes and prices.

They all have the same basic concept, though: operate with gas and require periodic maintenance.

Gas chainsaws obviously require fuel in order to run. This fuel can create an explosion hazard if proper precautions are not taken. In addition, these saws produce a significant amount of exhaust so be sure to take proper safety measures when using one.

Gas-powered saws also require you to mix the fuel before you can use it. They have an engine that requires a fuel mixture of gasoline and oil. This mixture must be shaken before use, otherwise the engine will not perform well or at all.

Makita 12V Max CXT Recipro Saw RJ03R1 from our website

The direction in the manual that came with your chainsaw should outline the proper fuel mixture for your saw.

It is also important to regularly change the oil in your chainsaw’s engine. Otherwise, it could wear down and stop working altogether. Most saws require you to do this after every 25 hours of use.

Consult the owner’s manual that came with your chainsaw for maintenance instructions.

Another type of chainsaw is an electric one. As the name suggests, this operates on electricity rather than gas. This means there is no risk of the saw detonating or leaking fuel.

Electric saws do not produce any exhaust and are generally considered to be safer to use around people who are sensitive to airborne particles.

However, due to the fact that they are powered by electricity, these saws are generally a lot more expensive than gas-powered ones. They also may require special maintenance such as keeping them dry if they come in contact with water, which many models do.

The last type of chainsaw we will discuss is a cordless chainsaw. As implied by the name, this is a chainsaw that operates without being plugged into an electrical outlet. It is powered by a battery, and while this does make the chainsaw safer to use because there are no exposed electrical components, there are still some safety concerns when using one.

First of all, these saws do not have as much power as their corded counterparts. This means they may not be able to cut through bigger pieces of wood as easily or at all.

Also, since they are battery-powered, you run the risk of the saw dying halfway through your project. Always be sure to keep spare batteries on hand.

The Dangers of a Chainsaw

No matter what type of chainsaw you decide to use, there are some inherent dangers associated with them. These are machines, after all, and can cause severe injury or death if used improperly. Here are some safety tips to keep in mind whenever you use a chainsaw.

When you operate any chainsaw, it is important that you wear protective gear. This includes heavy-duty work gloves to protect your hands, sturdy boots to protect your feet, and safety goggles to protect your eyes.

While most chainsaws don’t spew out as much debris as their woodcutting cousins, they can still cause serious leg and foot injuries if used carelessly. Keep a good grip on your chainsaw at all times and only use it when you are sure of your footing.

It is also important to avoid wearing any loose-fitting clothing while operating a chainsaw. Tuck in your shirts, snap your overall straps, and ensure your pants are secure around your feet. Loose clothing can get caught up in the chainsaw’s teeth, and you certainly don’t want that to happen.

Wear long pants in general when operating a chainsaw. While most people think of shorts as comfortable workwear, the reality is they offer little protection against a chainsaw’s spinning teeth.

Finally, never operate a chainsaw when you are under the influence of drugs or alcohol. While it may seem like a good idea at the time, even a small amount of alcohol in your system can make you less coordinated and more prone to accidents.

Always be aware of your surroundings when operating a chainsaw. Never cut wood in a closed-off area. You want to be able to get out quickly in the event something does go wrong.

Before you start your chainsaw, always ensure that the device is in good working order. Check all the buckles and clasps on your protective gear and be sure that your chainsaw’s chain is properly oiled and sharpened. Always wear leather gloves when handling a running chainsaw.

Also, before cutting any wood, ask yourself if it is really necessary. If there is any question in your mind as to the strength of a tree, then don’t cut it down. Always err on the side of caution.

Before you start cutting, always cut away from yourself. In other words, never guide the teeth toward your body when cutting wood. Also, never place your thumb or any other body part in the direction of the blade’s rotation.

This is especially important when performing an auto-chop with smaller pieces of wood.

Narrow cuts are more manageable than wide ones, so be sure to cut wood into smaller pieces whenever possible.

Don’t use your chainsaw to remove frozen or immobile objects. Forcing a chainsaw through an unmoving object can lead the object kick back and cause an injury. It is better to invest in some bolt cutters or call a professional.

Whenever you set down your running chainsaw, be sure to keep it in an area where no one can trip over it. Also, be sure to keep your chainsaw in an area where it won’t get rained on. Most chainsaws are not weather resistant and can rust if left out in the rain for too long.

If you’re using a corded chainsaw, be sure to unplug it after each use. Likewise, if you’re using a gas chainsaw, be sure to empty the gas tank after each use.

Routinely check your chainsaw’s oil level. Oil is the key to a smoothly functioning chainsaw. Most chainsaws have a window that allows you to check the oil level without having to empty it.

If your chainsaw does not have this feature, you can always unscrew the oil cap and check the oil level through there as well.

“A sharp chainsaw is a safe chainsaw.” Most chainsaws come equipped with a chain sharpener. Always use this feature before and after every job.

It will only take a few minutes but can make a big difference in how safe your operation is.

Keep your chainsaw clean after each use and it will serve you for years to come. It is always best to perform a routine check of your chainsaw before each use and keep it clean as well. A bit of your time can prevent injuries that may otherwise take place if you rush the maintenance process.

Also, try to avoid cutting at an extreme angle. The more perpendicular you are to the wood when you make the cut, the safer the process will be.

Whenever you’re cutting something, maintain a firm grip on the saw at all times while still keeping a good amount of distance between yourself and the saw blade. While it may seem counterintuitive, this will actually allow you to guide the chainsaw with more finesse and keep it from bucking as much.

While your chainsaw is running, do not touch the blade, as it can easily cause a nasty injury. Additionally, do not attempt to tip it over so that you may read the brand name etched on the blade. This is another task best left to professionals and could result in a chainsaw wound.

If you need to verify the blade brand for some reason, you can always ask the person who sold it to you or consult your owner’s manual.

Some of the many types of injuries that can occur from using a chainsaw include lacerations, amputations, and even decapitations. Even if you’re wearing all of the safety gear in the world, there is still a chance that something could go wrong. Always be mindful of this when operating any type of heavy machinery.

Wear protective gear such as ear defenders or ear plugs, a respirator or even a gas mask, sturdy boots, and gloves.

Make sure the chainsaw you’re using is the right size for your body. Using a chainsaw that is too heavy for you to handle can be very dangerous.

If you’re working in an area with other people, never operate a chainsaw above your skill level. This may seem like common sense, but it’s all too easy to allow your pride to get in the way of good judgment. Always err on the side of caution and avoid an accident that could cause permanent damage.

Be sure to properly train anyone you may let use your chainsaw. Even if they’re experienced, there is always something new to learn when it comes to using a chainsaw.

Ensure that your chainsaw is in good working order before using it. This means checking the oil level and replacing any parts that are defective or worn. A chainsaw that isn’t working properly is a major safety hazard.

Chainsaw injuries can usually be avoided with regular maintenance and care. This may seem like a hassle at first, but you’ll quickly get in the habit of performing these tasks after awhile. Not only will it help to prevent accidents, but it will prolong the life of your chainsaw as well, saving you money in the long run.

Always be sure to keep your chainsaw properly lubricated. A chainsaw is a machine that requires a certain amount of maintenance in order to work at its best. Without proper lubrication, it will quickly wear down and become damaged which can result in an accident.

However, before you perform any type of maintenance on your saw, you’ll need to turn it off and allow it to cool down for at least ten minutes. Never attempt to work on a chainsaw that is still hot. Additionally, never try to force your chainsaw to start.

If you’re having trouble getting it started, there is usually a problem with the equipment or you haven’t given it time to warm up. Attempting to force it will only result in damage.

Always wear safety goggles or safety glasses whenever operating a chainsaw. Even if you’re wearing ear defenders, there is always a risk of wood chips and other debris becoming airborne. This could hit your eyes and damage your vision.

Safety glasses will protect your eyes from these dangers. Wearing gloves will also help protect your hands and arms.

Never cut through frozen wood with a chainsaw. Although chainsaws are designed for cutting through frozen materials such as ice, snow, and even metal, you still run the risk of the chainsaw becoming jammed or the blade binding. This could cause the chainsaw to kick back and result in injury.

Makita 12V Max CXT Recipro Saw RJ03R1 from our website

Wait until the material is completely thawed before attempting to cut it.

When cutting wood, always cut along the grain. Cutting across the grain can cause the chainsaw to become stuck or even jammed, which could result in an accident. By cutting along the grain, you will be able to get a cleaner and smoother cut with less risk of an accident occurring.

Be sure to chain your clippings. Although most of the wood you cut will probably be left behind, it only takes one piece to fly back and hit you in the face. Additionally, keep your face and body at a 90 degree angle to the chainsaw blade.

If you need to stop working for any reason, be sure to turn off the chainsaw and set it down on the ground. Never just set it down, or even drop it. Always place it down on a safe surface and use the brake.

This will ensure that the chainsaw doesn’t accidentally start up again and cause an accident.

How to Sharpen a Chainsaw

Although most of the time your chainsaw shouldn’t need any sharpening, there are times when you’ll need to perform this task. The chain will either need to be sharpened or replaced depending on how blunt the edges have become.

To sharpen the chain, the bar and chain must first be separated, this can be done by removing the bar cover and then removing the screws connecting the bar to the chain. Once this has been done you should be able to remove the bar by hand.

The filing device should then be installed onto the chain, this will vary depending on your chainsaw brand and model. Each device will have instructions to help guide you through the process.

Before beginning, you should also prepare a container with oil, this will be used to coat the filing device when you are done.

Begin by placing the chain onto the filing device and making sure it is secure. If you are unable to place it onto the device, you may need to loosen or tighten the screws on the side of the filing device.

Makita 12V Max CXT Recipro Saw RJ03R1 - Picture

Begin filing the chain, this can be done by hand, but it will take a very long time. Using an electric grinder will significantly speed up the process.

The filing process must be done slowly and carefully, if you file too much the chain will become too thin and will break easily. It is best to remove and then re-fit the chain onto the filing device several times during the process to check if more filing is required.

Once you are done, you will need to thoroughly oil the chain using the can of oil you prepared at the beginning of the process.

Re-assemble the chainsaw before testing it and ensuring it runs correctly.

Always be careful when sharpening a chainsaw as you could seriously injure yourself or even lose a finger.

How to Store a Chainsaw over Winter

If you live in an area that experiences a colder winter, you may need to store your chainsaw over winter. This will prevent it from becoming damaged while the weather becomes too cold and the chainsaw will be safe until you need to use it again in the warmer months.

To store a chainsaw, you first need to turn off the saw and then let the chain slowly come to a stop. Be careful not to pinch your fingers while doing this.

Once the chain has stopped moving, you should spray a light coat of oil onto all the moving parts of the chainsaw. This will help prevent rust from forming as well as allowing for the chainsaw to be used more easily once it is taken out again in the spring.

Once this has been done, you need to store it somewhere that has a consistent temperature and that is safe from potential water sources. An example of a bad place to store a chainsaw would be an uncovered outside porch where it could be rained on or snowed on and where the temperature could fluctuate wildly.

The best place to store the chainsaw is in a garage or shed that is specifically designed for the purpose. When storing a chainsaw in a shed or garage, you should start by removing the bar from the chain and placing it into the chainsaw. The chain can then be wrapped in a cloth before being stored in the chainsaw’s case.

The chainsaw should be placed into the shed or garage in such a way that it is not likely to be knocked over and that its case is not likely to be damaged.

Lastly, you should take all of the oil that remains with the chainsaw and pour it into an old milk jug. This can then be stored in a safe place until next year when you will replace the oil with fresh oil before using the chainsaw again.

Makita 12V Max CXT Recipro Saw RJ03R1 - Image

Storing your chainsaws over winter is very important as it allows you to prevent damage to the saws while allowing you to use them again the next year. If you don’t store your chainsaws then they will not last as long and will require more maintenance during the year.

How to Maintain a Chainsaw

Maintaining your chainsaw is very important as it keeps it working well for longer and can help prevent serious injury.

In order to maintain your chainsaw, you need to perform routine maintenance on a monthly basis, weekly basis and a daily basis. These procedures are quite simple and only take a few minutes of your time. If these procedures are neglected then the chainsaw is likely to become dangerous and will require professional repair or replacement.

If you maintain your chainsaw, it will last longer and be more likely to work when you need it the most.

The first form of maintenance that should be performed is the monthly maintenance. This should ideally be done on the first day of every month. The monthly maintenance involves checking the fuel, oil and chain.

Once a month, you need to check that the saw has enough fuel. A chainsaw uses a variety of different types of fuel depending upon the type of saw. The most common types of fuel are gasoline and diesel.

Before beginning work, you should check that the chainsaw has enough of this fuel to keep working for the next month.

You also need to check the oil levels. Most chainsaws have an oil reservoir which needs to be kept filled with oil at all times. If it isn’t then you need to fill it up with oil before beginning work again.

The final part of monthly maintenance is the chain and bar. The bar is the metal arm which holds the chain and the chain itself. The bar and chain should be kept clean of debris and dirt in order for the saw to work properly.

Makita 12V Max CXT Recipro Saw RJ03R1 at

The best way to do this is by using a wire brush to remove any dirt from them. Once this has been done you can then apply a thin coat of oil to both the bar and the chain in order to ensure that they don’t rust while being stored over the next month.

Once this has been completed, the monthly maintenance is finished.

The weekly maintenance should be completed every week and consists of oiling the saw. In order to oil your chainsaw you need to turn it on so that the chain can move freely. Once this is done, you need to remove the cap from the bars reservoir which contains the oil.

It may be a good idea to wear safety goggles during this process as there may be some splashing of oil during this process.

Once you have removed the cap you need to fill the reservoir up with chainsaw oil. You should refer to the manual in order to determine the correct type and amount of oil. It is best to use motor oil as this is a common type of oil which can be used.

Once the correct amount of oil has been added, you should check if there are any leaks. In order to do this, turn the chainsaw on and then hold it at a 90 degree angle. Any oil which leaks out needs to be cleaned off and the reservoir needs to be refilled until no more oil leaks.

Once this has been completed you can turn off the chainsaw and you have completed this week’s maintenance.

The daily maintenance of the chainsaw is simply intended to keep the chainsaw running smoothly while you work. The best way to do this is by frequently using it for short bursts. This allows the motor to stay running without overheating and stopping.

The daily maintenance can be completed in just a few minutes, but it is very important to the general running of the chainsaw. If you work in short bursts of 15 minutes then the saw is likely to stay cooler and last longer than if you worked continuously for hours on end.

Once again, this is all part of the general upkeep of the chainsaw and not a repair.
