Peculiarities

The Patriot trademark is a brand of American origin, which today has its production facilities all over the world, including Asian countries, as well as the post-Soviet space. The bulk of chainsaws and electric devices are manufactured in China. In Russia, this tool appeared on the market just a few decades ago and rather quickly stood out among the line of similar construction and household equipment.

When it comes to Patriot electric saws, this line is distinguished by a number of features.

• All modern models are equipped with powerful and functional motors with double electrical isolation. This characteristic has a positive effect on the service life of the tool.
• Original spare parts and components stand out for their high quality level.
• The electric tool belongs to the category of universal garden and construction equipment, due to which the products are quite in demand among professionals or summer residents.
• Saws stand out for their safety, which concerns the environmental friendliness of the equipment. This is due to the absence of any harmful emissions during operation for humans and the environment.

The concern also offers a wide range of gasoline units. A similar tool can be used for small-volume work, as well as for cutting large quantities of wood-containing materials. Such a gradation allows you to choose a productive and affordable tool for any need.

And also in the line of the American brand are cordless saw models, which have a lot of positive feedback from the owners. However, such devices, as a rule, are several times inferior in performance to gasoline and electric counterparts, therefore they are recommended for household use.

Gasoline devices

Advantages

1. Power - gasoline power plants allow you to get more power and provide higher performance compared to electric models (from 2 to 10 kW depending on the model).

2. Reliability - chainsaws are not afraid of rain or snow, many are perfectly adapted to temperature extremes, the gasoline engine is not afraid of voltage drops (since it is not powered by electricity).

3. Mobility. Chainsaws run on gasoline and do not require constant access to the mains. It is convenient to transport such a saw, you can take it into the forest and other places remote from electrical networks. Chainsaws are also useful on construction sites, at stages when the electricity has not yet been supplied.

4. High productivity. Chainsaws are divided into classes, depending on the power and purpose:

• household gasoline saws - power 2-3 liters. with.;
• semi-professional chain aggregates - power 3-6 liters. with.;
• professional chainsaws - power 6-13 liters. with..

5. Two-stroke engine. It runs on a mixture of gasoline and two-stroke oil, has a long service life, high power. Internal combustion engines installed in gasoline units are air-cooled and are not susceptible to overheating, depending on their class, the duration of cutting without stopping can range from 45 minutes to several hours. The duration of work per day can vary from 2 to 12-14 hours (depending on the class and model).

6. Chainsaws are prepared for temperature extremes, many are equipped with special winter-summer switches, pressing the toggle switch in the “winter” mode turns on the heating of the handles and the carburetor.

7. Most gasoline units are equipped with a primer - a manual fuel pump that helps to start the chainsaw by pumping the fuel mixture into the carburetor.

8. The presence of an inertial chain brake and a protective guard, as well as a chain catcher, will reliably protect the operator of the equipment from a rebound during a kickback, provide the necessary safety for the operator during work.

9. Anti-vibration system. Special dampers and rubberized pads effectively dampen vibration that occurs during sawing.

10. Chain lubrication. The oil supply is carried out by an automatic oil pump and can be regulated or unregulated.

eleven.The chain tensioner is located on the side of the gasoline unit and can be instrumental or toolless.

disadvantages

1. Presence of harmful exhaust gases, it is forbidden to work indoors.

2. The high price of a chainsaw.

3. More complex preparation for work and maintenance:

• installation of equipment, chain tension;
• preparation of a fuel mixture in appropriate proportions from 2T engine oil and unleaded AI-92 gasoline;
• refueling the chainsaw with technical fluids (chain oil and fuel);
• complex launch (descriptions in the instructions);
• checking the conditions and performance of idle, lubrication, brake system.

4. Vibration. The anti-vibration system does not fully cope with its tasks, therefore, with prolonged use, fatigue affects.

5. The mass of chainsaws (especially in the pro and semi-pro class) is quite large, and this requires additional efforts and endurance on the part of the operator.

6. Noise. Chainsaws are very loud, in order to reduce the noise level, some manufacturers supply the unit with a silencer, but these measures are not always effective.

Chainsaw at work

Gde and for what purposes is it better to use gasoline chain saws

1. Professional chainsaws are most appropriate in logging companies, in farms and communal services, where high productivity, speed, endurance, long-term increased loads are needed.
2. Chainsaws are also indispensable in households, where you need to prepare fuel for the season, make a log house, build a bathhouse, a barn, dismantle any old building, tidy up the garden and surrounding areas.

3. Construction is another use for chainsaws. Electric saws are ideal for indoor use, chainsaws are perfect for outdoor work - sawing logs and thick planks of hard rocks.

When choosing a chain saw, it is important to decide for what purpose it is taken and in what conditions it will be used. There are high-performance models among both gasoline and electric units.

The ideal, but costly option is chain saws from well-known world manufacturers.

If finances do not allow - do not despair, lesser-known companies also have good inexpensive models. It would also be nice to go to the forum and read reviews about this or that model you like, talk to the owners of the equipment directly, and clarify the features of the chainsaw.

Design features of electric and gasoline chain saws

Chainsaw device

The basic unit of the chainsaw is a high-speed engine (12 - 14,000 rpm) with a volume of 40 - 60 cm3. A feature of such an engine is that gasoline of the A92 or AI95 brand is mixed with a special oil immediately before filling the tank. If you refuel the chainsaw with clean gasoline, the engine will fail a few seconds after starting.

Interlocked with the engine:

• centrifugal clutch;
• leading sprocket;
• tire;
• chain lubrication oil pump;
• brake.

The engine is started with a recoil starter (lanyard). The handle of the chainsaw is equipped with an anti-vibration mechanism and a special inertial protection - if the saw chain gets jammed, it can be thrown back strongly, there is a real possibility of injury to the sawer. The protective arc, when it comes into contact with the operator's hand, instantly stops the engine and eliminates the possibility of damage from the rotating chain.

Saw chains are used in several types, for their selection the most often used classification is by pitch - the distance between the lower teeth that mesh with the drive sprocket.

The chain thickness is in the range 1.3 - 1.6 mm. For household and semi-professional saws, chains up to 1.45 mm thick are sufficient, for professional ones used for felling wood, chains with a thickness of 1.5 - 1.6 mm are needed.

1. Tire. 2. Chain 3. Inertial chain brake 4. Cylinder cover.

5. Starter handle. 6.Safety trigger 7. Throttle trigger 8. Throttle lever.

9. Rear handle. 10. Oil tank cap 11. Front handle 12. Fuel cap.

Electric chain saw device

The saw headset of an electric saw is similar in design to a chainsaw. But in an electric saw, as a rule, there is no clutch; instead, a soft start button is provided. In many cases, this is completely insufficient - the idling mode, when the motor is running, but the chain does not move, is more convenient and safer.

In terms of engine power, electric saws are significantly inferior to gasoline ones - the maximum power does not exceed 2.5 kW. Attempts to create more powerful electric saws have not been crowned with success - the mass of the engine and the power consumption increase sharply, which affects both the convenience of the tool and its cost.

A protective arc, in most cases, is on each electric saw and works according to the same principle as on a gasoline one. An oil pump is also present - often pumps of the same model are installed on electric saws as on chainsaws. They provide chain and bar lubrication in all operating conditions. The oil flow rate depends on the chain speed.

It is worth noting that one of the main mistakes of electric saw users is hidden here. If in a chainsaw oil is poured into the pump tank every time you refuel, then when using a chainsaw, this is often forgotten. This leads to rapid wear of the saw headset and frequent replacement of chains and bars.

There is a misconception that on electric saws, the chain and tire wear out faster due to low speed. If you fill in oil on time, then the resource of the saw headset is the same in both cases. Only productivity depends on the speed.

4. Inertial chain brake 5. Tire.

6. Chain. 7. Bar fixing screw and chain tension.

Operating instructions for the electric saw Partner P820T

Using the example of the Partner P820T electric chain saw - one of the top-end household models, we will consider the features of operation, maintenance, and safety of the tool. The manufacturer strongly recommends that you strictly follow the operating rules when working with an electric chain saw:

1. There must be no unauthorized persons in the work area. The site of work must be prepared accordingly, calculate the place of the likely fall of trees and branches.
2. It is necessary to follow the recommendations regarding the worker's clothing: thick overalls, gloves, goggles, earmuffs.
3. The use of various attachments for the Partner electric saw is allowed only in accordance with the instructions. It is forbidden to use the tool for purposes not prescribed by the instructions.
4. The chain should be serviced in a timely manner: an unlubricated, poorly tensioned, not sharpened chain can provoke an emergency.
5. The handles of the chain saw must not be oiled, otherwise control over the equipment may be lost.
6. It should be remembered that the instrument generates an electromagnetic field that can affect the operation of medical implants to varying degrees.
7. When working with an extension cord, it is imperative to take into account the length and cross-sectional area of ​​the cable.

The main malfunctions of the Partner electric saw:

1. If the saw does not start, check the mains voltage, ring the mains cable and the input / output sections.
2. The engine is overheating - the gear may have jammed due to wood waste contamination.
3. The Partner electric saw stops during operation - the reason is mainly due to wear of the brushes or a malfunction of the gearbox.
4. The brushes and the collector were worn out and burned out - manifested in arcing, deterioration of the interaction between the electrodes and the armature. The brushes must be replaced with new ones; the gap between the lamellas in the anchor must be thoroughly cleaned.

The HUSQVARNA brand range of chain saws also includes cordless models of electric saws. Recharging is carried out using a battery in the charging / operating mode 35/35 min. With such a saw, you can, regardless of the power supply and fuel, perform the necessary work within half an hour, then put the tool back on charge.

Safety and maintenance instructions

• When buying a tool, check its completeness, make sure there are no breakages and visible damage to the insulation of the electrical wiring and the motor;
• It is forbidden to work with damaged insulation, it is also dangerous to carry out repairs using insulating tape;
• Be sure to apply the chain stop brake before the first start. Perform this procedure every time after completion of work;
• When operating the electric saw, use personal protective equipment. Wear tight clothing and shoes, gloves, face shield or goggles;
• Operation of the electric saw during rain or snow is not allowed. Moisture can not only damage the engine of the tool, but also cause significant harm to the health of the operator;
• Store the saw in a dry, ventilated area. Monitor the condition of the batteries: in cold weather it is better to remove them and move them to a heated place;
• Do not overload or overheat your saw. If the overheating sensor is triggered, let the engine cool down;
• Monitor the correct operation of the automatic chain lubrication system, add oil to the tank in time;
• When working in open space, use extension cords designed for external work;

Unpacking and first launch

Your Champion saw is delivered assembled. The new owner only needs to mount the saw headset and pour oil into the filling tank of the automatic chain lubrication system.

Champion manufactures electric saws with conventional and toolless chain tensioners. In both cases, installing the saw headset and adjusting the chain does not take much time and effort.

Let's consider the first option:

• Remove the protective cover;
• Place the bar on the splines, put the chain on the bar and drive sprocket;
• Mount the protective casing and fix it with nuts, do not clamp them all the way;
• Using a screwdriver, set the correct chain tension with the adjusting screw. In this case, the links should not sag, and the cutting edges of the teeth are set in the direction of the chain movement.

Toolless tensioning option:

• Remove the protective cover;
• We mount the tire on the mounting slots, put on the chain;
• We fix the protective cover and the saw unit with the inner tensioner nut;
• Adjust the chain tension with an external nut;
• We securely fasten the saw headset by tightening the inner tensioner nut until it stops;

Typical malfunctions, options for their elimination

Electric Saw Oil Champion

The correct operation of the automatic lubrication system is extremely important in the operation of any electric chain saw. There is an opinion that any mineral or semi-synthetic oil can be used as a lubricant. This is not entirely true. Gardening equipment manufacturers have developed special adhesive oils specifically designed to lubricate saws.They have such additives and viscosity index that they literally adhere to the chain and tire, increasing the performance and the life of the components.

Champion recommends using the following chain oils:

• Champion BAR & CHAIN;
• Champion SAE 30
• Husqvarna Chain Oil;
• STIHL ForestPlus;
• Liqui Moly Suge-Ketten
• MANNOL Kettenoel

What are the criteria for choosing a chain saw

The first thing I would like to start considering electric chain saws is the companies that produce them

This point needs to be given special attention, since it directly affects the quality of the selected tool.

Today, the most famous are electric chain saws offered by the following companies:

1. PATRIOT.
2. BOSCH.
3. SPARKY and many others.

Choosing an electric saw of any of the above brands, the consumer can be sure of the high quality of the product and its reliability. However, on sale you can find models of other brands, which, despite the lesser popularity, are still worthy of attention due to their compliance with European standards.

First of all, they are able to attract the attention of the consumer due to a more affordable price. The most prominent representatives of this list are the following companies:

• Interskol.
• EFCO.
• FORTE.
• Zenith.

In the light of the above, we can conclude that today such a tool as a chain electric saw is available to almost every consumer, regardless of his level of income.

If you are interested in a model of less well-known manufacturers, keep in mind that by purchasing such a unit, you get a tool that will not have very attractive properties. For example, some saws can be quite bulky, while others have a plastic surface, thanks to which it will not be very convenient to work with such a tool.

In addition, with such products, not everything is in order, and with ergonomics. Some manufacturers' products may not provide service at all.

For this reason, it is recommended to consider products from reputable manufacturers if you want to purchase a tool for frequent use. And do not be afraid of the higher price of such products, because all this will be compensated for by the high quality of the saw.

Having decided on which brand of electric saw is more suitable for you, you can proceed to the consideration of the technical characteristics.

Saw motor and power

with great power

In the event that you are interested in a model so that you can cut garden trees with it, then you can limit yourself to a unit with a lower power parameter.

In the first case, it is recommended to consider models whose power indicator is from 2.5 to 4 kW. In this case, we are talking about a professional tool used in industrial enterprises for timber harvesting.

But those who need an electric saw, which will be convenient to work in the country, should choose units with a capacity of 1.5 to 2 kW. These indicators correspond to the model of electric chain saws for household use.

If you follow the recommendations of specialists, then it is advisable to stop the choice on models of electric saws that have a small power reserve.An alternative here can be the option of sharing the tool with a special voltage stabilizer.

The need for this is due to the fact that often, where the summer cottages are located, there is a discrepancy between the voltage and the accepted standards. On top of that, from time to time in such territories, there is a decrease.

When such situations arise, certain changes occur in the operation of the engine, which is expressed in an increase in the current strength in order to compensate for the decrease in voltage. However, such situations do not benefit the engine, which reduces its resource.

Theory: the role of lubricant in the saw chain

The chain oil fulfills its main purpose - it lubricates the chain guide links, the guides in the bar and the driven sprocket. The lubricant should be fed slowly, ideally in a controlled manner, through a dedicated channel into the busbar groove. Further, the chain oil is captured by the guide links and distributed over the entire surface of the grooves, delivered to the teeth of the driven sprocket, reducing the influence of friction forces between the moving elements and the guide surfaces.

The oils for lubricating the chain of an electric saw are no different from those used in mechanisms with a gasoline power plant. The only difference is that not all electrically driven models have an integrated saw tool lubrication system. Lubricant in such modifications is delivered to the tire with a syringe, brush, or by dipping the saw element in an oil bath.

Some of the models of Shtil or Makita branded sawing units, which are electrically driven, are equipped with oil pumps with the ability to adjust the supply of lubricant. An increase or decrease in the amount of lubricant can be carried out in two ways: by changing the diameter of the channel for its passage or by changing the stroke of the plunger of the oil pump, for example, in professional Stihl saws. The screw for changing the feed is usually located in the lower or lateral part of the body, close to the place where the tire is attached. It is safer to adjust the plunger stroke in a specialized workshop.

Most electric chain saws do not have this adjustment by design and the oil is supplied in the amount specified by the manufacturer. The oil pump, if any, has a direct connection with the engine: the motor is running - oil is supplied to the chain. Stopping the rotation of the motor automatically stops the supply of lubricant. The oil flow in such saws can be changed in one way - by using lubricants with an invariant viscosity.

Not enough oil

Lack of lubrication naturally leads to local overheating of rubbing surfaces. The consequences of overheating and dry friction can lead to very sad consequences:

• tire deformation;
• premature wear of the tire guide groove;
• jamming and wear of the driven sprocket;
• seizure or open circuit.

All this not only can disable the electric saw, but also fraught with injuries.

Excess oil

Excessive lubrication does not lead to critical disturbances in the chain-bus pair. If you do not pay attention to the increased consumption of lubricant and contamination of the saw body with oil-impregnated sawdust, then you can follow the rule "porridge with oil ...". Meter emissions of oil splashes from the chain at high and medium engine speeds are another inevitable consequence of the excessive supply of lubricant to the chain saw.

Saw device

The lineup of gasoline tools is not distinguished by the complexity of the configuration, therefore it differs little from the standard equipment of such devices, but some characteristic features still deserve special attention:

• Patriot piston saw system has two compression-type oil scraper rings;
• the cylinder of the mechanism is equipped with a chrome-plated working area;
• ShPG for saws is produced from forged high-strength steel.

In the basic configuration, the devices consist of:

• a housing that includes a fuel tank, a motor and an oil tank;
• saw part represented by chain, bar and sprocket.

In addition, the manufacturer offers chainsaws with a convenient transport box, as well as a key used to assemble the unit. However, the equipment may vary depending on the model.

As for Patriot electric saws, it is worth noting the following features of their design:

• the equipment body includes an electric motor of various power;
• built-in automatic chain lubrication system;
• oil tank;
• saw system.
