Bar and chain brake

The bar and chain brake is an essential safety feature found in all modern chainsaws. It is designed to stop the rotation of the chain in the event of kickback or other unexpected movements. There are two types of bar and chain brakes: automatic and manual.

Automatic brake

An automatic brake is triggered by the inertia created from the sudden movement or kickback of the chainsaw. When the chainsaw encounters a sudden upward or forward movement, the automatic brake is activated, instantly stopping the chain rotation. This helps prevent accidents and injuries by reducing the risk of the chain coming into contact with the user or other objects.

Manual brake

On the other hand, a manual brake gives the operator more control over when to stop the chain rotation. By engaging the manual brake, the user can quickly stop the chain motion when needed, such as in emergency situations or when changing positions. This additional control enhances the overall safety of the chainsaw, giving the operator peace of mind and minimizing the risk of accidents.

Anti-vibration system

operating a chainsaw for extended periods can lead to fatigue and discomfort due to the intense vibrations it produces. To counteract this issue, modern chainsaws are equipped with anti-vibration systems.

Vibration-damping handles

Chainsaws with vibration-damping handles are designed to reduce the transmission of vibrations from the engine and cutting chain to the operator’s hands. This feature enhances comfort and minimizes the risk of hand fatigue and possible long-term health issues related to prolonged exposure to vibrations.

Anti-vibration mounts

Another component of the anti-vibration system is the inclusion of specially designed mounts that isolate the engine from the chainsaw body. These mounts absorb the vibrations generated by the engine, further reducing the overall vibration transmitted to the operator. By effectively minimizing vibrations, the anti-vibration system helps prevent hand and arm fatigue, allowing for longer and safer operation of the chainsaw.

Chain catcher

The chain catcher is an often overlooked, but crucial safety feature in chainsaws. It serves as a safeguard in case of chain failure, preventing the broken chain from flying off and causing potential harm.

Purpose of chain catcher

The primary purpose of a chain catcher is to catch or stop the chain if it breaks or derails during operation. By catching the chain, it prevents the broken pieces from becoming dangerous projectiles that can injure the user or bystanders. This adds an extra layer of protection and significantly reduces the risk of accidents while using a chainsaw.

Importance of chain catcher

The importance of a chain catcher cannot be understated. Without this safety feature, a broken chain could potentially cause severe injuries or property damage. By having a chain catcher in place, the risk of injury is significantly minimized, providing users with peace of mind and a safer working environment.

Reduced kickback features

Kickback is a sudden and unexpected thrusting motion that occurs when the chainsaw’s moving chain contacts an object or encounters a pinched or binded log. To combat kickback, modern chainsaws are equipped with reduced kickback features.

Low-kickback chain

A low-kickback chain is designed with modified cutting teeth and depth gauges to minimize the risk of kickback. These chains are engineered to have a shallower tooth profile and reduced chipper depth, which reduces the aggressive cutting action that can lead to kickback. By using a low-kickback chain, the user has more control over the chainsaw and can operate it with greater safety and confidence.

Chain brake

In addition to a low-kickback chain, chainsaws also feature a chain brake as a preventive measure against kickback. The chain brake is engaged when the front handguard is pushed forward or when the saw encounters a sudden movement. By rapidly stopping the chain rotation, the chain brake helps reduce the chances of a kickback occurrence and minimizes the risk of accidents or injuries.

Throttle interlock

The throttle interlock is a safety feature designed to prevent unintentional engagement of the throttle trigger. It serves as an added layer of protection and control when operating the chainsaw.

Function of throttle interlock

The throttle interlock operates by requiring the user to press a specific lever or button before activating the throttle trigger. This ensures that the chainsaw will only start when intentional pressure is applied to the interlock mechanism, preventing accidental activation. This safety measure helps reduce the risk of unintended start-ups, which can lead to dangerous situations or injuries.

Importance of throttle interlock

The throttle interlock is crucial for maintaining control over the chainsaw and preventing accidents caused by unintended throttle engagement. By requiring a deliberate action to activate the throttle, the chainsaw operator can safely maneuver the tool without the fear of accidental engagement, providing a higher level of safety and peace of mind.

Chain guard

The chain guard is an essential safety feature that protects both the operator and the chainsaw itself from potential hazards and debris.

Protects against flying debris

During chainsaw operation, debris such as wood chips or sawdust is often thrown into the air by the cutting action. The chain guard acts as a barrier, preventing these flying particles from reaching the operator’s face or body. This protective measure helps ensure the safety and well-being of the person operating the chainsaw, reducing the risk of eye or facial injuries.

Prevents contact with the chainsaw chain

Furthermore, the chain guard acts as a physical barrier, preventing accidental contact with the chainsaw chain when not in use. This is especially important during transportation or storage, as it reduces the risk of cuts or injuries when handling or carrying the chainsaw. The chain guard provides an effective safeguard against unintentional contact with the sharp chain, promoting safe handling practices.


The handguard is a vital safety feature specifically designed to protect the operator’s hands from kickback-related injuries and flying debris.

Protects against kickback

Kickback is a sudden and forceful backward movement caused by the interaction of the chainsaw chain with an object. The handguard acts as a shield, providing a barrier between the operator’s hand and the chain, reducing the risk of contact during a kickback event. By protecting the hand from potential injuries, the handguard significantly enhances the safety of chainsaw operation.

Shields the hand from debris

In addition to kickback protection, the handguard also serves as a shield against flying debris. As the chainsaw cuts through materials, debris such as wood chips or sawdust can be propelled towards the operator. The handguard acts as a barrier, preventing these particles from reaching the operator’s hand, reducing the risk of injuries or distractions during operation.

Front and rear hand guards

Chainsaws equipped with both front and rear hand guards offer an added layer of protection for the operator.

Shield from falling branches

During tree felling or cutting operations, there is always a risk of falling branches or timber. The front and rear hand guards provide additional shielding for the operator’s hands in case of accidental contact with these falling objects. By protecting the hands from potential impacts, these hand guards minimize the risk of injuries and ensure a safer working environment.

Minimize the risk of hand injuries

By offering protection from both the front and rear, the combination of front and rear hand guards maximizes safety. These hand guards act as barriers between the chainsaw chain and the operator’s hands, reducing the risk of cuts, lacerations, or other hand injuries that can occur during chainsaw use. This comprehensive hand protection is essential for operators, allowing them to work confidently and safely.

Safety trigger lockout

The safety trigger lockout is a vital safety feature that prevents accidental starting of the chainsaw. It ensures that the chainsaw can only be activated intentionally and operated by authorized individuals.
