Common Knowledge of Chain Saws: Differences between Electric Saws, Chain Saws, Air Saws, and Chain Saws

Chain saw is one of the most widely used and frequently used power tools among many garden machinery products. Someone asked if it's better to buy a chainsaw or an electric saw. What is the difference between a chainsaw, an electric saw, or an air saw? Actually, this is very simple. Today, the editor will analyze it for everyone and summarize several common problems with chainsaws.

What is the difference between electric saws, chain saws, gas saws, and chain saws?

Electric saw, also known as "power saw", is a cutting tool that uses electricity as its power to cut wood, stone, steel, etc., with sharp teeth on the edges. There are two types of saw blades: fixed and portable. The saw blade is generally made of tool steel and comes in various shapes, including circular, strip, and chain.

Chain saws are chain saws, and there is no difference between the two. Portable saws powered by gasoline engines are mainly used for logging and timber making, and their working principle is to use the cross movement of L-shaped blades on the saw chain to perform shearing actions.

An air saw is a pneumatic tool that uses air as its power to cut wood, plastic, and other materials.

Is it better to buy a chainsaw or an electric saw to cut down trees?

The chainsaw has a relatively high power, sufficient horsepower, and is relatively durable, but it is difficult to maintain. The chainsaw operation is simple, the noise is low, but the price is high. If the workload is relatively large, consider chainsaws. If the workload is not particularly large or for household use, choose chainsaws. There are now rechargeable chainsaws and additional batteries to meet the demand, but the cost is relatively high, and chainsaws are cheap and durable. Keripu chainsaw has high cost-effectiveness, saves fuel and time, and has a high horsepower.

How does the oil pump of a chainsaw work?

The working principle of a chainsaw oil pump is that the vortex rod drives the turbine to rotate, using the principle of volume ratio to create a negative pressure in the oil tank. Under the action of atmospheric pressure, the oil pressure is fed into the oil pipe and transported to the guide plate and chain. The oil pump assembly of the chainsaw is a major part of the two-stroke chainsaw lubrication system. It provides oil to the high-speed running chain and guide plate to prevent excessive heat generated by friction during operation, which can cause the temperature of the chain guide plate of the chainsaw to be too high and reduce work efficiency. The lubrication task of the chainsaw engine is completed by two-stroke engine oil in the fuel.

How to disassemble the chainsaw flywheel?

That's the reverse thread. You can use a hammer to hit the clutch spring retainer counterclockwise. Generally, thread sealant is applied to the threads of an unmoved chainsaw. It's best to use a hot air gun to bake it first, which is easier to remove.

Why is it easy to start the chainsaw after working for a period of time, but it turns off when the fuel door is filled?

This is a situation where the engine stalls at high temperatures. First, check the cylinder pressure to see if there is a slight pull, and check if the carburetor and fuel tank filter head are dirty. If they are dirty, replace them.

How to install the chain of the logging chain saw when it falls off?

First, remove the fixing plate and loosen the fastening bolts of the saw chain to install it. After installation, tighten the fastening bolts until the saw chain can be easily pulled. Remember the direction when removing, otherwise you will have to redo it.

What is the reason why it is difficult to restart the chainsaw after it stalls at high speed?

There should be no problem with cold starting. If it is difficult to start again after stalling at high speed, it is likely that the cylinder has been pulled. You need to go to a professional repair shop or contact after-sales service to replace the piston and cylinder.

The reason is that when the engine starts, the heat expands, and there is a gap between the piston and the cylinder block, resulting in no air tightness after expansion. The engine cannot absorb enough oil and air, and although it can ignite, the thin oil and air will generate higher temperatures, resulting in larger gaps; At the same time, the thermal expansion thrust after ignition also loses from the gap, causing insufficient piston thrust, a decrease in power, and ultimately a double layer superposition resulting in flameout.

Through the above analysis, I believe everyone knows that these common problems with chainsaws can be helpful to everyone.
