The five safety features on a chainsaw include:
1. Chain Brake: This safety feature is designed to stop the chain within milliseconds when the brake lever is activated by the user, or if the user lets go of the rear handle. This reduces the risk of a kickback event (when the chain or the guide bar is forced backward toward the user).
2. Throttle Interlock Lever: This feature prevents the chainsaw from being started until the lever is pressed, which tells the system that the user’s hand is in the correct position to use the tool.
3. Chain Catcher: Situated at the tip of the guide bar, this safety feature prevents the chain from coming off the bar during operation.
4. Chain Tensioner: This helps to ensure that the chain is properly tightened around the guide bar – any slackness increases the risk of recoil.
5. Chain Angler: The chain should be angled away from the user at all times and the chain angler helps to adjust the chain angle, helping to reduce the risk of kickback.
How do you safely use a chainsaw?
When using a chainsaw, it is essential to take safety precautions.
First, always read the operator’s manual before using the chainsaw to make sure you understand the manufacturer’s instructions. Wear the appropriate protective equipment, such as gloves, steel-toe boots, chaps, face shield, and hearing protection.
Also, dress for success and always work with a saw-tipped lanyard attached.
Before starting the chainsaw, inspect it for any damaged or worn out parts that may cause the blade to malfunction. Check the oil and fuel levels and fill if necessary. Also, ensure the chain catch is securely in place and the chain is tensioned and sharpened correctly.

Can you ruin a chainsaw chain?
Yes, chainsaw chains can be ruined or damaged in several ways. The most common causes of damage or ruin include bluntness due to wear and tear, as well as improper maintenance. For instance, if a chain is not sharpened properly or regularly, this can lead to bluntness, which reduces the efficiency of the chain and increases the risk of kickbacks and other accidents.
Additionally, if a chain is not lubricated properly or regularly, the chain can become stuck or clogged and result in it becoming ineffective or unusable. Finally, if a chain is not stored properly, the links can become rust or corrode, resulting in a weakened chain that is no longer able to cut properly.
To ensure that your chainsaw chain remains in optimal condition, it is important to perform regular maintenance and ensure that it is stored in a dry place when not in use.
What is the most common chainsaw injury?
The most common chainsaw injury is laceration or amputation of a limb, usually a hand or a finger. Every year, approximately 55,000 people go to the emergency room for chainsaw-related injuries, with over 36,000 of those patients requiring treatment in a hospital, according to the Centers for Disease Control and Prevention (CDC).
The injury is typically quite severe, as the blades of chainsaws are sharp and powerful, capable of slicing through bone and muscle. Other common chainsaw-related injuries include penetrating trauma from the blade, puncture wounds, crushed or avulsed tissue, fractures, and nerve damage.
How does a chainsaw kickback?
Kickback occurs when the chainsaw chain is suddenly stopped while the chainsaw cutting bar is in contact with a hard object. This can cause the cutting bar to get stuck and it will then cause the entire chainsaw to kickback towards the person using the saw.
The chainsaw kickback phenomenon can be violent and can cause significant injury to the user, so it is important to take measures to reduce the risk of kickback by using a low kickback chainsaw chain and keeping the chainsaw in good working condition.
Additionally, it is important to know how to handle a chainsaw safely, including always making sure the top of the chainsaw bar is pointed away from the user and holding onto the chainsaw firmly with both hands.
It is also important to cut slower and make sure the chain is correctly adjusted and properly lubricated so it can glide through the material being cut. Finally, it is important to only work with the recommended cutting tools and to never try to use a chainsaw to cut materials that are not designed for this type of application.
Do a complete inspection of the chainsaw before starting which includes?
Before starting a chainsaw, it is important to conduct a thorough inspection. This includes checking the fuel and oil level, the mesh of the chain and the tension of the drive system. The chain brake must also be tested to ensure it is working properly.
Additionally, look for any visible signs of damage, such as worn-out wiring and worn-out parts, to ensure that it is in proper working condition. Make sure that all the parts are securely fastened, especially the handles.
Finally, make sure the chain is properly lubricated and sharpened. Doing these steps will help ensure the chainsaw is safe to use and will help prevent unexpected incidents.
Do you need a Licence to use a chain saw?
In most places, yes, it is necessary to have a license to operate a chain saw. Each state and municipality will have its own set of regulations for the operation of chain saws, so it’s important to determine what’s required in the location you plan to use the chain saw.
Depending on the state, you may need a license or certificate to operate a chain saw, or you may need to take specific safety classes in order to be certified for using a chain saw. In some cases, you may also need to get an approved face shield and other safety equipment before you are allowed to use a chain saw.

What does 72 mean on a chainsaw chain?
The number 72 on a chain saw chain identifies the pitch and gauge of the chain. Pitch is the distance between the drive links (the part of the chain that engages with the sprocket) and gauge is the thickness of the drive links.
A 72 chain means the pitch is 3/8 of an inch, and the gauge is low profile which is 0.043 inches thick. Different chain sizes will have different characteristics like cutting smoother, cutting faster, having higher kickback resistance, and requiring different amounts of power from the chain saw.
Selecting the correct chain for your chain saw is important for proper chain saw performance and user safety.
What happens if you run a chainsaw with the brake on?
If you try to run a chainsaw with the brake on, the result could be extremely dangerous. The chainsaw’s chain brake is designed to stop the chain from moving when it is engaged, and is one of the key safety features of a chainsaw.
Trying to run the saw with the brake on can cause the chain to bind and put immense pressure onto the clutch and flywheel, potentially damaging the engine and resulting in a dangerous kickback, which is the sudden and forceful movement of the chainsaw towards the operator.
In some cases, the damage caused to the chainsaw may be enough to make the chainsaw unusable, or even dangerous to operate. Therefore, it is important to remember to always keep the brake off before running a chainsaw.
Are there different types of chainsaw chains?
Yes, there are different types of chainsaw chains that vary according to their size, pitch, and type (e. g. ripping or chipping chain). Chainsaw chains come in three basic sizes: 3/8th inch, 0.404 inch, and 3/4 inch.
Depending on the chain size, the pitch of the chain can be 1/4 inch, 0.325 inch, 0.381 inch, or 0.50 inch. Chainsaw chains also differ in type, such as ripping or chipping chain. Ripping chain has fewer, larger teeth set at wide intervals, resulting in faster and more aggressive cutting of wood fibers.
This type of chain is ideal for cutting logs and other tough timber. Meanwhile, the chipping chain has more, smaller teeth set at narrower intervals, resulting in a smoother, more precise cut. This type of chain is better for trimming and pruning branches and twigs.
What is the advantage of a skip tooth chain?
The main advantage of a skip tooth chain is that it provides a much smoother and quieter operation when compared to a standard chain. This is because there are fewer contacts between the teeth and the chain, as the gaps between the teeth are larger.
Because of this, the chain is less likely to snag or cause excessive vibration, resulting in a smoother ride. Additionally, the lack of contact between the chain and the teeth reduces wear and tear on the chain, meaning it could potentially last longer.
For these reasons, skip tooth chains are the preferred choice for many off-road vehicles.
Why will my chainsaw not start?
There could be several reasons why your chainsaw will not start. It could be that your chainsaw is out of gas, the spark plug is not working, the chain tension is too loose or too tight, or the air filter or fuel filter may be clogged.
If your chainsaw is out of gas, fill it with the correct mixture of fuel and oil and try again. If the spark plug is not working, check the plug for corrosion or fouling then replace it if needed. If the chain tension is too loose or too tight, adjust it to the correct tension.
Lastly, if the air filter or fuel filter is clogged, replace it with a new one.
