Everything You Need To Know About A Battery-Powered Chainsaw

About A Battery-Powered Chainsaw
Are you looking for the battery powered chainsaw ? If you plan to buy one, you need to learn some essential information to ensure maximum safety and performance.

In this article, you will know what exactly a battery-driven chainsaw is, what does it offer, and how to maintain the machine properly.

What is a battery-powered chainsaw?

It is a handheld chainsaw powered by a battery. And this machine works by running a saw-toothed chain over a guide bar, creating an elongated chainsaw “blade” to cut objects.

Chainsaw sizing

Chainsaw sizing

Make sure to choose the right size of your desired chainsaw since both too large and too small units can cause some issues. It may become a safety hazard or force the motor to overwork.

Based on the length of the guide bar, there are three main sizes of chainsaws as follows:

The mini size
The guide bar length of the mini-sized chainsaw is about 12-14 inches. And the motor is from 30-40cc. It suits residential users who need to trim overhanging branches.

The mid-size
The guide bar length of this size is 16-24 inches. Its motor is in the 40-60cc range, which is more powerful than the mini size. Thus, it can deal with medium projects very well.

Heavy-duty

This is the biggest size, even some of you may find it too outrageous. The guide bar length is over 24 inches in length while the power ranges from 60cc to 120cc.

Why should you use a battery-powered chainsaw over a gas or corded chainsaw?

Below are the key reasons:

Compared to 2-cycle and gasoline models, it’s easier to use a battery-driven saw.
When using a 2-cycle or gasoline saw, you may need to handle petrochemicals, breathe toxic exhaust fumes, and put up with loud engine noise for a long time. These negative things result in some obvious health risks. Meanwhile, the best battery-powered chainsaw won’t bring these issues.

Let’s discover more specific reasons:

Less engine maintenance than 2-cycle and gas models
Unlike the big engine of a battery-powered chainsaw, the smaller engines need more expensive maintenance over the years.

In particular, if you leave the fuel in the engine over the winter, some actual chemical changes will happen, for example, losing several volatile compounds, causing oxidation.

For first-time users, transporting, mixing, and storing gasoline are hazardous tasks. Moreover, it takes longer to fill your engine with gas than popping a battery into your machine.

On the other hand, the engine of the 2-cycle saw features many parts that will wear out over time.

Safe and convenient cutting when up high

Using a battery-powered chainsaw is more beneficial than a 2-cycle model when you are in a tree or a lift.
For example, when you need to talk to someone on the ground, you have to turn off the machine to stop the noise, then you must start again. With the gas model, it’s essential to pull to start, which is very dangerous when you are up high. However, in case you use a battery-powered chainsaw, just letting go of the trigger will give you a quiet atmosphere.

Low cost

A long working day with a saw requires a lot of power from fuel and energy from batteries. And fuel is obviously far more expensive than batteries. Thus, using a battery-powered chainsaw helps you save a lot of money on buying fuel regularly.

If your battery-powered chainsaw has the ability for solar charging, it helps you save a lot of operating costs within 3 years.

After filling your chainsaw with high-quality bar and chain oil, follow the instruction from the manufacturer. You should run the machine within 30 seconds to make sure that the oil is lubricating.

When starting, cut the small branches from top to bottom. If you cut those supporting the whole weight of the tree, there will be unexpected accidents.

To remove these branches quickly and conveniently, you had better cut them into small and manageable pieces.
For the best felling cut, cutting a notch in the tree helps you direct it in falling in the desired direction.

Some notes while cutting:
Read the safety information on the manual.
Wear protective items to protect yourself.
Make a specific plan before cutting.
Hire a licensed professional for big projects.

How to maintain a chainsaw

Chainsaw maintenance plays a vital role in keeping your model in good working condition. Keep in mind the following tips:

Sharpen the chain
You always have to keep a sharp blade for the chainsaw to perform its function properly. The duller the blade is, the more your motor must work, especially, a dull blade increases safety risks.

Can you manually sharpen your chainsaw yourself?
Yes, but it will take you a lot of time.
Remember to prepare a chainsaw filing kit and a step-by-step guide.

Keep your chainsaw clean
After each use, you have to remove all debris and dust from your machine properly. Remember to clean mud and sand as well. If not, there will be a lot of corrosion on your chainsaw.

Chain tension
Chain tension is vital for the proper operation of the tool. A too-tight chain can cause it to stall while a too loose chain can break mid-cut or cause it to come off the guide.

Therefore, let’s adjust the accurate tension through a tension screw located on the guide and near the motor. Most models available on the market allow you to access the screw without removing the cover, but some of them require you to disassemble the housing. Even many models are designed with a built-in adjustment knob to tighten and loosen the chain quickly.

Lubricate the chain
Properly lubricating the chain helps you minimize friction when it moves along the guide bar. This is also a very effective way to maintain a high level of cutting power. What’s more, lubricating can decrease the workload on your motor.

Store properly
It’s better to store your chainsaw in a case or a sheath because the biggest part of the chainsaw exposes all the time. If you don’t protect this metal part carefully, there will be unnecessary corrosion.

Why should you use the best battery-powered chainsaw?

Battery-powered chainsaw helps you complete your cutting projects quickly and easily. It produces less noise and toxic exhaust fumes, especially, it offers better maneuverability.

Radar Detector: The Best Bud For All Drivers

Radar Detector: The Best Bud For All Drivers
When you drive on the road, what scares you the most? Is that accident? Yes, but not that big concern as I know we all watch out for this. How about a speeding ticket? Hooray! We all hate this (and the traffic police too). No matter how carefully you drive, just a moment of carelessness and a ticket will fly to your windshield.

I guess that is the right time you look for a best radar detector 2020 (RD). But what is it? How can it help you out? We will give you all the information about this useful device in today’s article. But first, let’s go back in time a little before the first RD came to life.

Traffic police and radar/lidar speed gun

If you ride a bike, you can forget about this article and leave now. If you own a vehicle such as a car, a truck, or a motorbike, guess you are all familiar with the phrase “exceed the speed limits.” And if you violate this, there will be a solid ticket for you, no question asks. The police use speed gun to sort you out.

The speed gun was not invented until the late 1940s. Before that period, traffic officers used the stopwatch to estimate the vehicle speed. Two officers stood apart, each held a stopwatch. The average velocity of the vehicle passing by is calculated by the distance traveled divided by time elapsed. This sounds familiar to you, right? I guess you can imagine the scenario here.

The invention of the speed gun is a real relief for the traffic officers. This device helps them to measure the vehicle speed by just one… shoot! You will not get hurt by this gun, but your wallet will. That is when the radar detector came along, but not until the 1970s.

Later in the 1990s, lidar guns (Light Detection and Ranging) were developed and have been proved to be more effective than radar guns. They are commonly used by the police, especially in developed countries.

Is radar detector a bad thing?

When the first radar detectors (RDs) were invented, not everyone accepted them. Those who always live by the laws consider RD as dangerous equipment. They represent “racing license” to speed lovers, in other words, highway “ghost riders.” Some automobile associations and organizations despise RDs.

The government and the police detest them for sure. In fact, the device is prohibited in many countries and regions around the world. Australia, Brazil, Japan, North Korea, Singapore, and the USA (not all states) are some common names in this list.

However, things have changed over time. Many people now recognize that RDs are actually useful safety devices. Statistics show that RD users are less likely to have accidents. RDs help to remind drivers to watch out for their speeds. So normally they will have to slow down instead of trying to be a “highway hero.”

Similar studies have been conducted in some big countries like the US and Australia, and the results are quite convincing.
Radar Detector

How does radar detector work?

RD is like a radio receiver, or the FM and AM broadcasting. The air space is full of frequency signals, including TV signals, radio signals, or even signals coming from the remote control. An effective signal receiver must selectively catch signals in a specific range.

Simply put, a radar detector for the money works exactly like a radio receiver. The only difference lies in the signals each device capture. While the radio receiver is designed to capture signals in the AM and FM bandwidths, the RD receiver must be synchronized with the frequency of electromagnetic waves emitted by the police speed gun.
The frequency range is classified under 3 different types. They are X-band (frequencies of 10.500 – 10.550 GHz), K-band (frequencies of 24.050 – 24.250 GHz), and Ka-band (frequencies of 34.200 – 35.200 GHz). The first two are very easy to be detected by RDs, while the latter is much harder.

Every time the police introduce a new type of speed gun, RD manufacturers will immediately launch a new RD line to detect those new guns. The chase between Tom and Jerry seems to never end.

RD can recognize radar signals from a distance up to a couple of miles. One thing is for sure that the longer the distance, the easier you can adjust your speed. However, longer distance means it is harder to catch the signal. So your RD must be equipped with a strong transceiver, which means you have to spend more money.

Does radar detector work effectively for 100%?

The answer is no. Sometimes, RD will give a false warning due to interference from radio waves from other sources such as automatic doors, security systems of buildings, and traffic lights. Or when you drive near the post office, cell phone tower or even an ambulance.

How to choose a good radar detector?

There are many different models of RD from dozens of different manufacturers. For ease of comparison, users often divide them into groups based on their prices. For example, we have models under $99, from $100 – $150, $150 – $200, $ 200 – $250, $300-400 and over $400.

Besides, there are many trustworthy websites that specialize in analyzing and evaluating RDs. You can find useful advice to choose the best and most affordable RD from those sites. One recommendation site for you is radartest.com.

So before shopping for a best radar detector 2021, you need to go over some factors.

Budget
How much are you going to invest in your RD?

The brand
Leading RD manufacturers include Cobra, Uniden, Whistler, Bel-Tronics, Escort, and Radenso. Many other companies also produce RD and are even OEMs (original equipment manufacturer) for well-known brands.

Radar wavelength
Choose an RD that can detect a wide range of radar bands (X, K, Ka, and VG2) and lasers (lidar gun).

Type of RD
There are 3 types of radar detectors, which are corded, cordless, and remote-mounted device. There are advantages and disadvantages to each type.

Corded RD is cheaper with a wider detection range. However, it may take up more space in your car. If you have more than 1 car, cordless RD is a better choice.

Corded radar detector
For corded/cordless devices, it is visible to thieves and police because you may have to place it on the windshield. If you want to hide it where no one knows, go for remote-mounted RD. Of course, this device will cost you more money and time to install.

Special features
There are many additional features you may need to consider for you RD

Voice alert & volume control
Some older models warn you with the display on the screen. This may cause distractions while driving. You can go for the one with a voice alert so you can stay focused on the road while being alerted at the same time.

360 degree
Some types of RD only receive signals from the front and ignore the signals coming from the side and behind. Select the one with the 360-degree feature to protect you from all directions.

City/ highway mode
As state above, RD can sometimes give you a false alarm. This becomes a frustrating issue when driving in the urban where many interfering signals may fool your RD. An RD with city/ highway mode to switch between is always a better choice.

GPS
This feature will give you a warning on all the locations where the speed and red-light cameras are set up.

Conclusion

What can be a more truthful answer for a need of RD than to avoid getting a speeding ticket? You do not want to get financially hurt. Hopefully, this article will provide you with some useful knowledge about radar detectors as well as how to choose an effective one.

Anyway, just remember that driving carefully within speeding ranges is still the best solution.

What were chainsaws invented for?

When-was-the-Chainsaw-Invented

With those who are using chainsaws, they might probably know what chainsaw was invented for. However, there are still some people being curious about this question. They might wonder if the chainsaw were originally invented for cutting wood, and how the chainsaw develops from the past until now. This is the place where you can find the answer.

1. The very first chainsaw

Actually, the chainsaw was originally invented for cutting the woman’s pelvis when she gets hard to giving birth. The first chainsaw was invented by a Scottish doctor, John Aitken, and James Jeffrey, it was called “osteotome” which is the device to widen the pelvis if the baby’s head as too large to pass through. This device used as a watch chain, and remove the other parts of the diseased bone.

2. The history of cutting wood chainsaw

The first chainsaw that we are now used to, or cutting tree or logging wood, was invented in 1920. The development of motorized saw results in the more increase in timber production compared to the time of using an axe.
The history of forest runs parallel to the human race. The chainsaw was invented to support human works in the forest. Lumberjack was the lowliest of the social ladder. However, it was changed with the introduction of the modern chainsaw.

3. From axe to chainsaw

The axe is the oldest tradition of all wood cutting tools used by humans. It was used massively for felling trees right into the 19th century. However, around 5000 B.C Germanic invented the first saw. They nicked the small teeth into half-moon shaped flints. If these laws were used for working on wood is not known.

After they discovered the copper, it was used in the form of bronze to produce axes and saws. About 750B.C iron replaced bronze as the material but saws still remained out of bronze for many centuries. Nevertheless, It was not be used much in the forest, more by doctors and surgeons.

Until the 16th century, there was no clue that hand saws were used in the forest. However, saws mills which cut trunks into planks has been around for several times in the forest. About 1500 Leonardo da Vinci also spent some time on the saw. He sketched the first saw teeth which worked both by pushing and pulling.

Around 1800 the first circular and band saw were produced in England.

What were chainsaws invented for?

4. The development of motorized saw

In the beginning, to make heavy forestry work lighter, they invented the machine, chainsaw. It has been creasing the productivity of works and bring more benefits.

1926: the rise electronic chainsaw was developed by Stihl
1927: the first petrol chainsaw invented by Dolmar
1950: The first two-man chainsaw came, this chainsaw weighed over 60 kilos, but the progress was still continuing. The aim was to develop the lighter, more powerful which can be used by one person. In 1950, the first one-man chainsaw was developed, it was still heavy. In 1959, they weighed about 12 kg while today it is just a half of it.
1964 the antivibration has been equipped for chainsaw
1972 the chain brake comes
1982 the quick stop or automatic chain brake was developed

5. Working with chainsaw

Sometimes, it is dangerous when working with a chainsaw. There is one accident per 1100 m of worked wood. The most exposed parts of the body are the left leg and the left arm. Kickback is the main cause of the accident which is the sudden rising of the saw when the chain and the nose meet the wood at the critical angle. The vibration of the machine can cause the white finger syndrome.

In 1981, there is a survey reported that irreversible hearing damage is restively rarely. Thanks to the technology used, it is hard to reduce to the noise level. There is some health problem caused by the exhaust fumes, but little is known for the long-term effects.

In conclusion

History about chainsaw is really interesting to find out. What I have shown you just a small part of long chainsaw history. Just when you use chainsaw frequently, you might consider much more about what happened with it in the past. Understanding more about chainsaw history also helps your work more exciting.
