The chainsaw is a portable electric tool that cuts wood through a fast-moving chain that rotates around a guide rod, so it can shorten the work of pruning, felling, tangling and felling trees. It is also considered the most dangerous power tool available without a license.

It is designed to cut with the top or bottom of the saw blade, but almost everything in contact with the upper part of the tip of the saw blade (called the recoil zone) can change the cutting momentum and cause the saw to violently counter you. Rebound can cause catastrophic injury, so users must take extra precautions and always follow the correct usage method to avoid using a chainsaw to avoid disaster.

Before picking up any chainsaw (high or low power, gasoline or electricity), be sure to take the risks seriously.

Basic safety tips for beginners or experienced Straight chain saw users
You can operate the chainsaw more safely and minimize the chance of recoil by keeping the chain sharp and tensioned and always cutting to a height below the shoulder.

Similarly, today’s low-power chainsaws (including electric models) (not developed for professional loggers, but for DIYers who want to cut wood by themselves and keep property trimmed) rely on low recoil chains, The chain can absorb less fiber recoil area during winding, minimizing the possibility of recoil.

Before trying to operate a chainsaw, please familiarize yourself with the safety precautions introduced here, and then follow our practical tips for safe and effective cutting.

Before you start
Whether you are learning an electric saw for the first time or in your daily work, do not operate this power tool alone. When something goes wrong, it happens very quickly. Having a friend nearby can save your life. If you work in the woods, please set up traffic safety signs next to the car. Make sure someone knows where you are and when you plan to return. Have a complete first aid kit and at least one coagulation bandage.

Wear all necessary personal protective equipment, including calves, chainsaw helmet with face shield, gloves and steel toe or logging boots. Do not wear loose clothing, as it may be jammed by saw teeth.

Find the correct posture to hold the saw
Find a comfortable posture and stand firmly with your feet while working. When rebound occurs, please hold the saw with two hands at a certain angle or one point or the other side, not directly in front of you.

Think twice before cutting
Do not operate the chain saw on the ladder, and do not cut the limbs higher than your shoulders. (If you want to cut taller things, consider using a completely different tool: a manual wire saw, usually called a pocket chain saw.) To remove the lower branches and supporting roots before cutting down the tree, cut down Thin and use the pull chain-this is the part of the chain that wraps the bottom of the bar. If the tree is on a slope, always climb from the tree.

In addition, please pay attention to the location of all power cords, and never fall on trees, where there are power lines, vehicles, buildings, especially people within two-half of the length of the tree.

Use the correct chainsaw
Use a chainsaw of the appropriate size for the work. If you want to rent a chainsaw, please discuss the scope of work with your employees to understand which size of motor they recommend, because the size of the blade is related to the power of the engine. Generally, the length of the blade should be two inches longer than the wood it cuts. Light wood cutting, etc. can be done with 14-inch blades, while 16 to 20-inch blades are suitable for medium-sized felling. The longer the blade, the more difficult it is to control. Therefore, novices should stick to blades less than 20 inches in length.

Do not mix the substance with the chainsaw
It should be self-evident, but we still have to say: When operating a chainsaw, please keep a clear head!

How to use a chainsaw
Step 1: Scan your work area.
Get familiar with your work area. Pay attention to your "escape route"-once the tree starts to fall, where you can safely move to. Your tree may fall in unexpected directions, so it is best to be prepared for any possible situation. Chainsaws are called "widowmakers" for good reasons-operating them can be dangerous. Make sure to have a plan and understand the terrain you are working on. Step 2: Prepare your own saw.
Put on all the gear from head to toe. Check your saw to make sure the chain has good tension. If you can pull the chain from the guide bar and loosen the chain link from the guide or "nose", the chain is too loose. You need to reduce tension to prevent injury. Please check your machine's maintenance guide for instructions on tightening the chain. In most cases, you will use the "screw" (screwdriver/wrench) that comes with the machine. A properly tightened chain should bend slightly when pulled, but it should not leave the guide.

Step 3: Archive the depth gauge.
If you have a gas engine, check the gas level and fill the tank before you start. For a two-stroke engine, gasoline and oil are likely to need to be mixed in the fuel tank. Buy two-stroke engine oil and add it to the fuel tank at the ratio recommended by the manufacturer (usually a ratio of 50:1, which is about 2.6 ounces of oil per gallon of gasoline). Fill the chain lubricant reservoir with chain oil.

Step 4: Engage the chain brake.
Lay the chainsaw flat on the ground with the bottom facing down. Push the chain brake forward until it locks. The chain brake is usually a separate lever located between the top handle of the saw and the saw blade, which prevents the chain from rotating until you release the brake and depress the accelerator.

Step 5: Perfuse the saw.
If you are using an air saw, but it has a throttle valve, please open it. If there is a primer button, press it four to six times to draw gas into the carburetor, and then turn on the power switch. If your chain saw is electric, all you have to do is press the safety switch and turn on the power switch.

Step 6: Fix the saw and pull up the starter handle.
The person with the chainsaw can proceed to step 7. For those with an air chain saw, pass the right foot through the rear handle, and press the heavy object on the handle to secure the saw. Use your left hand to firmly fix the front handle in place. Use your right hand to yank the starter cord to its full length. It usually takes four to five pulls to start the engine. If the engine "fires" but does not engage, adjust the throttle by pulling it out halfway.

Step 7: Be prepared.
Even after the engine is started, the chain will not turn. You need to press the trigger or throttle to move the chain. First, place your feet firmly and hold the saw firmly to position yourself correctly. Always cut the saw to the side or at an angle to you to reduce the damage when rebounding.

Step 8: Cut in.
When you are ready to cut, release the chain brake and fully engage the throttle. Place the saw where you want to cut. Do not apply pressure-the momentum of the chain and saw blade will suck the wood in. Never use force. If you are using a wire saw, make sure that you understand the rope and don’t let the rope feel helpless.

Step 9: Finish cutting.
Maintain a firm, stable grip and keep the throttle fully engaged during cutting. Release the throttle only after cutting or cutting the blade from the mowing (if you are cutting trees to cut trees).

Step 10: Turn off the saw.
To turn off the chainsaw, just turn it off. Please cool it down before storing.

If you are using a chain saw, you need to decide what to do with the remaining fuel in the tank before putting it away. If you plan to use the chainsaw again in the near future, you can put the remaining fuel in the fuel tank for up to four weeks, but if you wait longer, the ethanol in the fuel may block or block the project (this It means that you need to disassemble and thoroughly clean the carburetor before the next use). To empty the fuel tank, take the chain saw to a well-ventilated area and drain all remaining fuel into a plastic container.

You can usually dispose of the remaining fuel in your local car shop, but never pour this flammable substance into the soil, rain drains or trash, because these practices are dangerous and illegal. After the fuel is exhausted, ignite again (as in steps 4 and 5), and then run until it goes out, but the last fuel in the carburetor is used up.

Regardless of whether your chain saw is gasoline or electric, you should store it in a box or cover it with a protective cover to ensure safe storage and prevent dust and debris from falling on the chain.

Must-do chainsaw maintenance
In order to make the chainsaw work properly, please refer to the machine's instruction manual for two best practices:

Tension
Every time you use the saw, check the tension of the chain around the guide bar, because incorrect tension will affect the performance of the machine. A chain that is too tight is in danger of breaking, and a chain that is too loose can fall and cause injury. Your chainsaw should come with a combination screwdriver wrench with maintenance guidelines and "scratches" to adjust the tension of the chain.

Sharpen
Many chainsaws are self-sharpening. However, on an air saw, if you do not pull itself into the wood when cutting, or rebound when cutting, or seem to cut unevenly or at an angle, you should sharpen the chain. Every three to four gas tanks may require sharpening, but the exact frequency depends on the type of wood you want to cut, so pay close attention to changes in performance to help you determine when to sharpen.

Frequently asked questions about how to use a chainsaw
As the saying goes, great power comes with great responsibility-this of course can be applied to the use of chainsaws. Before launching this useful and powerful outdoor tool, please get answers to the following important questions.

How do you use the chainsaw correctly?
In the event of an accident, it is best to use a chainsaw with other people present. Make sure to wear all the necessary safety equipment mentioned above. Check that the tools are well maintained and ready to use, including sharp and tensioned chains.

When you are ready to start cutting, step on the ground (never use a chain saw on a ladder) and follow the 10 steps listed above.

What shouldn't you use a chainsaw for?
One of the most important things you shouldn't do with a chain saw is to cut in the recoil zone, which is actually the upper half of the end of the blade. In addition, do not cut your shoulders, and never operate the chainsaw under the influence of drugs or alcohol.

How do you use a chainsaw?
As far as safety precautions and cutting actions are concerned, the use of electric saws should be the same as that of gas-driven electric saws. The main difference is to start the tool. To start the chainsaw, you just need to plug it or insert it into the battery. Then turn on the motor according to the manual of the individual tool.
