Guide Bar Length
The guide bar length is the distance of the bar from the tip of the chain to where it enters the enclosure. The cutting power of a chainsaw depends on the guide bar length; the longer the guide bar, the more powerful the chainsaw and vice versa. The ideal guide bar should be 2″ longer than the wood size. However, you can still cut larger trees with a smaller guide bar, but perform the task in two passes. The problem with using a small blade to cut a larger tree is that it increases risk, reduces flexibility and things can go wrong quickly. The guide bar length is a vital feature to consider based on the work you do with your chainsaw. Also, remember that the difficulty of handling a chainsaw is proportional to the guide bar length. When buying a chainsaw, go for a model with an appropriate guide bar length you can manage safely.

Engine Power
Gas chainsaw power is a measure of the engine's cubic centimeters or cubic inches. The power of the chainsaw is proportional to the cc or ci rating, but so does the weight. Chainsaws come with engines of 20 to 50cc ratings depending on the job specification. If you need a chainsaw for light cutting tasks such as pruning, limbing and trimming, a 30cc engine is appropriate for your work. Light firewood requires a power rating of 35cc to 45cc while medium firewood needs a gas chainsaw with 40-50cc engine power. Moderate tree felling needs up to 45cc and above while heavy-duty cutting requires 50cc and higher engine ratings for effective cutting.

Safety Features
The chainsaw is one of the most dangerous hand-held power tools on the planet. Using one with poor handling skills or without using appropriate safety measures can lead to severe injuries, disabilities and sometimes fatalities. That is why you need to look out for safety features before buying a gas chainsaw. Also, know how to use your chainsaw correctly. In addition, you need to have the proper safety equipment and use them properly and always. It helps if your chainsaw comes with safety features such as

• Low-kickback bar
• Chain brake
• Automatic oiler system
• Throttle interlock

You also need to have the following safety equipment to reduce the risk of injuries while using your chainsaw.

• A safety helmet
• Eye protection
• Hearing protection
• Appropriate gloves for the task
• Leg protection
• Protective boots, preferably steel-toed
• Non-snag outer clothing, preferably made from high-visibility material

Level of Experience
Go for a chainsaw that fits your level of experience regarding operation, safety measures, and maintenance. Be sure to read the user manual before using the machine and always wear protective equipment. Professionals can afford to use the heavy-duty chainsaws, but every chainsaw user needs to use the tool with caution to avoid injuries.

Weight
Consider your fitness level, the period of use, and your ability to handle the machine for extended periods when choosing the suitable weight of a Cutting Wood Gasoline Chain Saw.

Ergonomics
Operating a chainsaw is a serious enterprise, making it essential to buy a model with ergonomic designs. A unit with a padded handle and anti-vibration mechanism will increase ease of handling and operator comfort. Look for a machine with the right balance, weight, size, and maintainability. Light and compact is best for enhanced handling and lower risks.

Noise Levels
Chainsaws are loud machines, and the noise increases with the size. If you are a homeowner who intends to use a chainsaw in a built-up area, go for a unit with low noise levels. A professional who fell trees in the wilderness has no problem using a large machine with high decibels as long as you protect your ears.

Handedness
All chainsaws are right-handed, so you may have difficulty getting used to one if you are left-handed. While you can increase control with practice, the tendency to make mistakes becomes higher as a chainsaw requires high levels of balance and coordination for proper use.

Chain Maintenance
The chain is the cutting edge of your chainsaw, which is why you need it to be in top shape always. Go for a machine with an easily accessible chain to make maintenance in-between jobs faster and stress-free. Models with automatic oilers and tensioner are better as they make your work easier and safer.

Automatic Oilers
When shopping for a gas chainsaw, it is better to choose a model with an automatic oiler. A chainsaw is as good as the amount of lubrication between the chain and the wood. An automatic oiler allows you to work fast and efficiently by bathing the chain in a continuous stream of oil, reducing friction and making your work easier, faster, and safer.

Tool-Free Assembly
Tool-free assembly means you need no hand tools to dismantle your chainsaw. A chainsaw with this feature makes your work easier and reduces maintenance time, thus helping you to cover more in less time.

Simple Start
Gas chainsaws require pull cords to start, and this can be daunting because of the air-fuel mixture in the carburetor. A Simple Start mechanism makes starting the engine less arduous, saving time and energy to do the actual work of woodcutting.
