How to Pick the Right 18-Inch Chainsaw?

To buy your ideal 18” chainsaw, you need to keep these factors in mind:

Bar Length - Tension

The first is its bar length or tension to keep the chains steady.

You can then cut effectively, enhance safety, and reduce the adjustment of the chains while using.

The trick here is to choose a tension system that doesn't require much work or tool-free.

Significantly, many chainsaws today have these systems, although you have to pay more to bring you high precision and safety.

Easy-To-Start Feature

Next is the easy starting feature, which is ideal for beginners because you need to use lots of effort and power for the starter cord.

Also, you have to do this action many times when handling a chainsaw and can damage the saw to cause problems due to putting high pressure on it.

Luckily, it’s easy for you to start many chainsaws today by simply pressing a single button.

Tooth Of Chain

You also need to check the size and material of the tooth.

Although a small tooth has good accuracy, it is not useful for heavy applications or massive hardwood cuts.

At the same time, you should look for durable carbide tooth chains if you can invest more on this saw.

Product Weight

Because you have to carry your chainsaw for a long time when cutting trees or wood, a lightweight chainsaw can help you to avoid pain and fatigue.

Although light models are less powerful, you can carry it everywhere with better accuracy.

Noise Level

Finally, consider the noise during operation.

Many manufacturers equip the chainsaws with noise reduction features. Remember to find the standard decibels ranging from 50-70 decibels.

The less the decibel level is, the better for the user's ears.

Can The 18-Inch Chainsaws Leak Oil? 

Yes, they can.

You need to apply oil regularly to the chainsaws.

Although many models have automatic oil systems and convenient design to fill and refill, there are still spills and leaks of this device.

To avoid this problem, you should follow the manufacturer's instructions to clean the machine properly and determine which wear and tear can cause leaks.

Do The Chains Of My Chainsaw Stretch?

Yes, they do.

If the saw does not have enough oil, the chain friction can rub with the guide, causing heating and wear faster.

You need to add enough oil to your blade to extend the chain life.

Worn sprocket also makes the chains stretch.

Your chains then can't attach to the sprocket, causing fit lost along with the guide.

You should see the manufacturer's instructions to change chains and sprocket.

Can The 18-Inch Chainsaw Get Overheat?

Yes, it can.

Because a powerful chainsaw motor runs at high temperatures, it can get too hot, especially in the summer.

The suction areas on the saw can be clogged with dust, debris, or oil accumulation, causing overheating. 

Therefore, you need to maintain and clean the saw regularly to prevent this problem.

Moreover, you should also keep the engine, guides, and chains clean and lubricate them to reduce friction and avoid overheating.

Should I Oil My Chainsaw Regularly?

Yes, you should.

Proper lubricating the chainsaw keeps it running smoothly and efficiently, and reduces overheating and wear.

As mentioned above, many products on the market have an automatic lubrication system for easy maintenance of the saw.

So, you just need to make sure that your saw has enough oil in the tank, and clean the device regularly for durable use.
