Chainsaws Echo (Echo) - models and technical characteristics

Japanese Echo chainsaws have gained popularity among buyers due to the high quality of the parts used, advanced production and assembly technologies, the introduction of mechanical developments, and the long service life of all elements.

The manufacturer offers semi-professional and professional equipment, which is manufactured using modern equipment. When developing new units, the company relied on feedback from users and specialized specialists in the field of maintenance and repair.

Various models of chainsaws are used in private households, construction and public utilities.

Advantages of petrol tools

The design of Japanese chainsaws is similar to that of other well-known manufacturers. But there are advantages that the Japanese gas powered tool Echo can boast of:

Economical and environmentally friendly power drives;
Minimum time for preparation for operation and maintenance;
Multi-stage aerofilters are used;
Safe implementation of complex work.

The official website of the ECHO INCORPORATED company provides a complete information catalog with a detailed description of all units and their cost.

Technical condition of the instrument

Do not use the saw if it is damaged, incorrectly adjusted, partially assembled or not securely assembled. Do not use the saw with a weakened or faulty muffler. Make sure the saw chain stops when the throttle trigger is released.

Sawing

Do not use a saw on wood unless you are specifically trained to do so.

Keep the saw chain away from you while the engine is running.

Use extreme caution when pruning small shrubs and young trees, as thin material can get caught in the chain and trip you, or cause you to lose your balance.

When felling or trimming branches and limbs, stand on the side of the log that is opposite to the direction the log rolls after cutting.

When pruning stretched branches and branches, be prepared for the possibility that they may spring back once the tension is released.

Sawing on a ladder is extremely dangerous because the ladder can be unstable and in this position, control over the saw is limited. Work at height must be carried out by qualified personnel.

Stand firmly on both feet. Do not work suspended/above the ground.

Stop the engine before putting down the saw.

Procedure for working with wood

Safety rules for working with a chainsaw require that the saw is in good condition, that the operator knows the structure and principle of operation of the chainsaw, as well as safe techniques for operating a chainsaw when performing the relevant types of sawing.

Persons who have not read this manual and have not understood the information contained in it are not allowed to use the saw.

Use this chain saw only for cutting wood or wood products. Do not use the saw to cut metal products, sheet metal, plastic or other non-wood materials.

Maintenance

All maintenance operations on the tool, other than those listed in the appropriate sections of this manual, must be performed by qualified personnel. (For example, using the wrong tool to hold the flywheel when removing the clutch can damage the flywheel structure and cause it to explode.)

WARNING

Do not modify the saw. It is permissible to use accessories and spare parts manufactured by ECHO or officially approved by ECHO for certain models. Some unauthorized accessories are suitable for use with ECHO products, but their use can be extremely dangerous.

ATTENTION

Do not touch the hot surface of the cylinder cap or muffler after using the chainsaw.

Adjusting the Echo chainsaw carburetor

Echo petrol tools are quite easy to use and maintain. But sometimes it becomes necessary to adjust the carburetor.

The Japanese instrument has three adjustable screws:

L to adjust the power plant at low speeds;
H for tuning the engine at high speeds;
T to adjust idle speed.

You can adjust the carburetor yourself at home. Procedure:

The chainsaw is started to warm up the engine;
When the chain moves on the bar, screw T turns counterclockwise until the chain stops;
Screw L is unscrewed clockwise to the maximum, then turned a quarter turn in the other direction;
The throttle trigger is clamped, screw H is turned a quarter turn counterclockwise;
The chainsaw starts again for a few seconds. At idle, the chain on the tire should not rotate - this is an indicator of the correct carburetor settings.

Owners of chain saws may encounter other problems:

The engine will not start;
The motor runs intermittently;
The engine immediately overheats;
Increased amount of exhaust gases with reduced power.

Reasons indicating a malfunction of the power plant. Often in this case it is necessary to replace the piston group. The tool is disassembled to remove damaged pistons. After installing new spare parts, the chainsaw is reassembled.

The manufacturer offers a wide range of units with various technical and operational parameters. They have a similar design, but with different capabilities.

Theory and principles of operation of the fuel system, carburetor design

The principle of operation of the carburetor

In different models of chainsaws, the design of the carburetor may differ, but the principle of operation of this part is always the same: the forced air flow moves in the direction of the air (pulse) channel, the air is regulated by the air damper. Entering the pulse channel, the air changes speed. The change in speed is affected by a special valve that closes the air inlet. Fuel is supplied into the air channel and mixed with the air flow. As a result, a flammable fuel-air mixture is formed, which then enters the engine and burns there.

Figure 3. The principle of operation of the fuel system using the example of a chainsaw carburetor with a two-stroke engine

The components of any carburetor are:

aluminum body (solid, cast);
jets or valves that regulate the amount of fuel entering the carburetor;
float chamber;
diffuser;
spray.

In Figure 1 you can see the location of the key components of the carburetor, and in Figure 2 you can see the appearance of the chainsaw carburetor. To properly adjust the carburetor, the chainsaw owner should know on what principle this part works:

when the engine starts, the air damper opens;
due to the stroke of the piston, rarefied air is formed inside the float chamber and in the air channel;
then the mass of air is sucked through the diffuser, where it is mixed with fuel, which also passed through the fitting into the float chamber, thus creating a fuel-air mixture entering the intake channels;
the last stage is the mixture entering the engine combustion chamber.

By adjusting the position of the damper, the chainsaw owner can either add air to the fuel or deplete it - this means that the fuel mixture will enter the combustion chamber faster or slower. Carburetor adjustment screws are used to adjust engine speed. An air filter is installed above the carburetor, which cleans the air before it enters the air duct.

Video showing a table for adjusting the carburetor of a Husqvarna chainsaw:

Figure 4. Table of proportions of oil-fuel mixture for Husqvarna chainsaws

Table of proportions of oil-fuel mixture for Husqvarna chainsaws

The carburetor unit of expensive and medium-cost chainsaws is designed almost identically. Cheap Chinese chainsaws often differ from expensive original chainsaw models in that they lack a number of parts in the carburetor unit. You can read about the features of adjusting the carburetor of Chinese chainsaws later in the article.

Step-by-step sequence of the adjustment process

Before you begin making adjustments, remember:

the adjustment is carried out only “hot”, that is, the engine needs to be started and warmed up for 10 minutes;
then the adjusting screw is turned counterclockwise and the chainsaw chain is stopped;
before adjustment, the chainsaw must be placed on a flat surface, and the saw part must be directed away from the owner;
for adjustment, three screws with letter designations are used, H - adjusts the upper speed, controls the main jet, L - adjusts the idle jet, adjusts the low speed, T - adjusts the idle speed.

Carburetor adjustment step by step:

Scroll screw L from left to right, or from right to left, find the maximum engine speed, then return 1/4 turn back;
do the same actions with screw H;
the chainsaw should run for a few seconds, the maximum engine speed is determined using a tachometer - their indicator should not exceed the maximum specified in the instructions for the chainsaw;
if the chain moves in idle mode, turn screw T in the direction of chain movement until the chain stops completely (idle speed is always adjusted only by screw T, which is rotated from right to left - counterclockwise - until the chain stops completely).

the threaded fastener has weakened, air penetrates through the resulting gap;
the jets are clogged with resinous deposits and need to be flushed with acetone;
The ignition is not adjusted.

Owner reviews

Alexander Kryuchkov:

I chose a saw for my father. We used it in the village for sawing firewood, and in winter we went into the forest. Several large pine trees were felled. Echo works like a clock. It doesn’t eat extra fuel, and it doesn’t overuse oil either. This summer we started a small construction project in the village - the chainsaw did not rest. I realized that it is ideal for renovation and construction. The Echo saw has already earned its price.

Artem Shiryaev:

I bought Echo on the recommendation of a friend. I read reviews on the Internet, talked with sellers - I bought it for household needs and to cut firewood. Although the tool is a household tool, it can cut down trees up to 55 centimeters (I haven’t cut any more). Moreover, the weight is such that branches can be cut with one hand. I liked how it started in winter: the first or second time. I have no complaints about the instrument – it’s truly Japanese.

Carburetor chainsaw device

Repair work is not complete without knowledge of the basics of the mechanism. By understanding the components and operating principle, it is easier to determine the cause of the failure.

Any malfunction in the carburetor threatens to stop the engine

The carburetor is one of the main functional parts of the engine, which is used to prepare and supply a fuel mixture consisting of certain proportions of fuel and air. As soon as the proportions are violated. the engine begins to act up or even stops working completely.

You can ensure proper operation of the carburetor by studying its “priming”:

Tube with cross valve to regulate air flow.
Diffuser. This is a constriction to increase air flow located at the fuel inlet.
The nozzle from which fuel is supplied (fuel arrow in the diagram).
A float chamber that regulates the fuel level at the entrance to the channel.

Here's what it looks like in a diagram:

Diagram showing the interaction of fuel and air flow

Operating principle: the air flow in the diffuser atomizes the fuel, creating a mixture that enters the cylinder. The greater the amount of fuel supplied, the higher the engine speed. Carburetors of different models work according to the same scheme.

3. Other precautions

Vibration and cold

A disease called Raynaud's syndrome, which affects the fingers, is thought to be caused by exposure to cold and vibration. Therefore, the ECHO chainsaw is equipped with vibration isolators designed to reduce the level of vibration that affects the operator through the tool handles. Under the influence of cold and vibration, tingling and hot sensations arise in the fingers, then the fingers turn pale and go numb. It is strongly recommended to follow all the recommendations given so as not to provoke the appearance of this poorly studied disease. Œ

Keep your body warm, especially your head and neck, feet and ankles, hands and wrists.

Keep your blood circulating well by taking frequent breaks and doing vigorous arm exercises.

Limit the amount of time you use the chainsaw. Plan your workday so that you can combine sawing with other activities.

If you experience discomfort, redness and swelling in your fingers, followed by paleness and numbness (loss of sensation), consult your doctor.

Injuries due to constant stress

It is believed that repetitive movements of the tendons and muscles of the fingers, arms and shoulders can lead to soreness, swelling, numbness, weakness and severe pain. To reduce the risk of injury due to repetitive strain, follow these guidelines: Œ

Do not bend or stretch your wrist. Try to keep your wrist straight. Hold the saw with all your fingers, not just your thumb and forefinger.

Take periodic breaks from work to reduce the load and give your hands a rest.

Reduce the speed and intensity of repetitive movements.

Do exercises to strengthen the muscles in your arms and hands.

Contact your doctor if you experience tingling, numbness, or pain in your fingers, wrists, or forearms.

Safety regulations

1. General safety precautions

Manual

Read the operating instructions for your chainsaw carefully. Become thoroughly familiar with the chainsaw's controls and how to use it correctly. Failure to follow these instructions may result in serious injury.

If you have any questions or problems, please contact your ECHO dealer.

Operator health requirements

Operation of the chain saw by persons who are tired or under the influence of alcohol or drugs is prohibited.

Safety regulations require that the operator be in good physical and mental health. Failure to follow instructions for use may result in serious injury or death. If the operator's health could be impaired by strenuous, physically demanding work, consult a physician before operating the chain saw. Do not use the saw if you are sick or tired, or under the influence of any substances or medications that can affect your vision, physical or mental condition.

Personal protective equipment (PPE)

Be sure to use eye protection. Chips, dust, breaking branches and other debris can be thrown by the saw chain towards the operator's face. Eye protection can also provide some protection in the event that a saw chain should fly off and hit the operator's eye area. If work conditions are such that a ventilated face mask must be used, eye protection must be worn under the mask.

The ECHO recommends the mandatory use of hearing protection. Failure to follow this recommendation may result in hearing loss. The risk of hearing damage is reduced by using headphones or earmolds that have been approved for safety by appropriate organizations.

All persons who regularly use saws should have their hearing tested periodically.

Always wear a helmet or hat when operating a chain saw. If work is carried out under trees or in places where there is a danger of falling objects, it is recommended to use a safety helmet.

Wear tough, non-slip protective gloves for better grip and protection from cold and vibration.

Use durable, closed-toe safety boots or boots with non-slip soles.

When working, do not wear loose clothing, unbuttoned shirts, shirts with wide sleeves or cuffs, scarves, ties, jewelry, chains, etc. that could get caught on a chain saw or branch.

Clothing should be made of durable material that provides protection. Clothing should fit tightly to the body so as not to snag or accidentally grab the tool, but be loose enough so as not to impede movement.

Trousers should not be too wide, without cuffs; they should either be tucked into the boot tops or shortened.

Protective jackets, special leg protection, sawing trousers made of protective material are all available for sale. The use of additional protective equipment under certain operating conditions is the responsibility of the operator.

It is not recommended to use the saw alone. Make sure that there is someone within earshot of the operator while the operator is working, in case you need assistance.

ATTENTION

It is not recommended to use cotton wool as ear protection.
