Chainsaws 2 HP Power

The choice of a chainsaw depends on various factors, including intended use, specifications and budget. Here are some key things to consider:

Type of use:

• Home use: For occasional cutting of branches and small trees, an electric or battery-powered chainsaw is ideal. They are lightweight, easy to use and low maintenance.
• Professional use : For intensive, long-term work, such as tree felling, a power chainsaw is more suitable due to its increased power and range.

Technical features:

• Engine power: The higher the power, the easier it will be to cut hard and large woods. Petrol chainsaws usually offer more power than electric chainsaws.
• Bar length: The guide bar must be proportionate to the size of the wood to be cut. A longer bar is suitable for large shafts, while a shorter bar is more manoeuvrable for precision work.
• Weight: A lightweight chainsaw is easier to handle, especially for elevated or prolonged work.

Safety and Comfort:

• Ergonomic handle: Ensures a comfortable grip and reduces fatigue.
• Anti-vibration system Reduces vibrations during use, improving comfort and safety.
• Chain brake: A good braking system is essential to avoid accidents.

Budget:

• Chainsaws vary widely in price. Cheaper options may work well for occasional use, while for professional use it is better to invest in a high-quality model.

The cost of a chainsaw also varies significantly depending on the type of use you want to make of it. Here is a general overview of pricing:

• Home use: These models generally cost between 100 and 300 euros. They are suitable for small garden work.
• Professional use : Professional models can cost between 300 and 800 euros, and in some cases even more depending on power and advanced features.

Light and handy chainsaws are ideal for pruning, gardening and small cuts. Here are some recommended features:

• Low weight: Chainsaws weighing less than 5 kg are considered lightweight and easy to manoeuvre.
• Ergonomic handle: Designed to provide a comfortable and stable grip.
• Compact size They facilitate use in confined spaces and transport.

To cut down large trees, it is essential to choose powerful and sturdy chainsaws. Here are a few things to keep in mind for this type of work:

• High power: Engines with displacements of more than 50 cc provide the power needed to cut hard woods.
• Long bar: A guide bar of at least 50 cm is required to cut large diameter logs.
• Durability and reliability: Chainsaws made of high quality materials to withstand heavy use.

Battery-powered chainsaws are becoming increasingly popular due to their many advantages over the combustion models. Here are just a few:

• Low weight: Battery-powered chainsaws are generally lighter, making them easier to handle and less tiring to use.
• Quietness: They produce less noise, making them ideal for use in residential areas and reducing noise pollution.
• Low maintenance: No oil or fuel changes are required and have fewer moving parts that can wear out.
• User-friendliness: They are easier to start (with the push of a button) and do not require fuel mixtures.
• Eco-sustainability: They do not emit exhaust gases, making them greener and safer for the environment.

However, battery-powered chainsaws also have some disadvantages over power-operated chainsaws, especially in terms of performance. We have collected the main ones below:

• Running time: Battery life may be limited. Replacement batteries are recommended for extended work.
• Power: Although the performance of battery-powered chainsaws has improved, for very intensive work a power chainsaw can still offer more power and durability.

Pruning chainsaws and cutting chainsaws have different purposes and specific characteristics for each type of work.

Chainsaws for pruning.

• Ideal for gardeners and arborists who need light and precise tools for tree maintenance.
• Weight and size: They are lightweight and compact, making them easy to use in confined spaces and for overhead work.
• Power: They generally have less powerful motors than cutting chainsaws, sufficient for pruning small branches and trees.
• Guide bar: The bar is shorter, usually between 25 and 35 cm, for greater precision and control.
• Handle: They often have a one-handed handle, making them easy to handle for detailed and precision work.

Chainsaws for cutting;

• Suitable for lumberjacks and forestry professionals who have to fell and section large trees.
• Weight and size: They are larger and heavier, designed to cut large trees and logs.
• Power: Equipped with powerful engines that can handle long and intensive work.
• Guide bar: The bar is longer, usually between 40 and 90 cm, allowing large diameter logs to be cut.
• Handle: They have an ergonomic two-hand handle to ensure a secure and stable grip when cutting.

Choosing the right bar for your chainsaw depends on a number of factors, including the type of work to be done and the power of the chainsaw itself. Here are the main ones:

Bar length:

• Short bars (25-35 cm): Ideal for pruning and cutting small branches.
• Medium bars (40-50 cm): Suitable for felling medium trees and cutting moderate logs.
• Long bars (more than 50 cm): Required to felling large trees and cutting thick logs.

Engine power:

The bar must be compatible with the power of the chain saw. A low-powered engine will not be able to support a bar that is too long, while a powerful engine can handle longer bars.

Wood type:

• Soft wood: Requires less power, so shorter bars may be sufficient.
• Hardwood: Requires more power and therefore longer bars.

Specific use:

• Pruning Short bars are easier to handle and more precise.
• Felling: Long bars allow thicker logs to be cut with fewer passes.

Compatibility:

Always check the chain saw's technical specifications to make sure that the bar you choose is compatible. Each chainsaw has a range of bar lengths recommended by the manufacturer.

The most common type for intensive and professional work, combustion chainsaws are generally equipped with two-stroke engines. Here are the main characteristics of these engines:

• Duty cycle: Two-stroke engines complete a combustion cycle in two piston movements (one outward and one return cycle). This means that the engine produces more power than a four-stroke engine of equal displacement.
• Lubrication: Lubrication is by means of a mixture of oil and petrol, which is burnt during engine operation. This system eliminates the need for a separate lubrication system.
• Power and weight: Two-stroke engines are lighter and more compact than four-stroke engines, offering a high power-to-weight ratio, ideal for portable chainsaws that need to be operated in various contexts.
• Maintenance: They require regular maintenance, including cleaning the air filter, checking and replacing spark plugs, and preparing the correct fuel mixture (usually a 1:50 ratio of oil to petrol).

Advantages of two-stroke engines:

• High power: They offer powerful performance for hard wood cutting and intensive work.
• Easy to build: Fewer components than four-stroke engines, which can result in increased mechanical reliability.
• Lightness The compact and lightweight design makes chainsaws easier to handle and less tiring to use for extended periods.

Disadvantages

• Fuel consumption: Two-stroke engines are generally less fuel efficient than four-stroke engines.
• Emissions: They produce more emissions and noise, although modern models are improving in these areas thanks to more advanced technologies.

Combustion chainsaws use a mixture of petrol and oil specifically designed for two-stroke engines. Here are some essential details about this type of fuel:

Petrol and oil mixture:

• Mixture ratio: Most two-stroke chainsaws require a mixture of petrol and oil in a ratio of 50:1. This means 20 ml of oil per litre of petrol. However, it is always important to consult the manufacturer's manual for the exact ratio, as it may vary between models.
• Petrol type: Use unleaded fuel with a research octane rating of at least 90. High-quality petrol helps prevent the formation of deposits in the engine and ensures efficient operation.
• Oil type: 2 oil bottles, specific for 4-stroke engines. These oils are formulated to burn clean and reduce carbon deposits.

Preparation of the mixture:

• Suitable container: Prepare the mixture in a clean, strong container, labelled to avoid confusion.
• Mixing: Pour the oil into the container first, then add the petrol. Close the container and shake well to ensure that the oil mixes completely with the petrol.

Storage:

• Storage period: The mixture of petrol and oil should not be stored for more than 30 days. Over time, petrol can deteriorate and cause engine problems.
• Sealed containers: Store the mixture in sealed containers and in a cool, dry place to keep it fresh.

The displacement of a chain saw is a key indicator of its power and cutting capacity. The choice of displacement depends on the intended use:

• Domestic displacement: 25-45 cc Ideal for small garden work, pruning and cutting branches. These chainsaws are lightweight and easy to manoeuvre, perfect for hobbyist users.
• Displacement for semi-professional use: 45-60 cc Suitable for more intensive work, such as cutting wood for the fireplace or cutting down small trees. These chainsaws offer a good balance between power and handling.
• Displacement for professional use: 60-80 cc Designed for long and heavy work such as felling medium trees and cutting thick logs. They are powerful and robust, suitable for woodcutters and forestry professionals.
• Displacement for extremely intensive work: Over 80 cc. Used for felling large trees and cutting large diameter logs. These chainsaws are extremely powerful and heavy, requiring adequate experience in use.

We can say that the engine of an internal combustion chainsaw can last between 10 and 20 years. However, the service life of a chain saw engine depends on several factors, including engine quality, maintenance and use:

• Engine quality: Engines from well-known brands such as Stihl, Husqvarna and Echo can last many years, even decades, if properly maintained. Engines built with durable materials and high-quality components tend to last longer.
• Maintenance: Regular cleaning of the air cleaner, checking and replacing spark plugs, and checking the chain are essential to extend the life of the engine. Storing the chain saw in a dry, weather-protected place helps prevent corrosion and other damage.
• Use Heavy and frequent use reduces the service life of the engine compared to occasional use. Heavy work, such as felling large trees, requires more effort from the engine, reducing engine life.

Proper sharpening of a chain saw is essential to ensure an effective and safe cut. Here are the main steps:

Tools required:

• Round file: Specification for chain size.
• File Guide: Helps to maintain the correct angle during sharpening.
• Depth gauge: To adjust the height of the chain teeth.
• Clamp: For securing chain saw bar when sharpening.

Sharpening steps:

• Cleaning the chain: Remove the chain from the chainsaw and clean it of oil residue and dirt.
• Fixing the bar: Secure the bar in a clamp to stabilise the chain.
• File placement: Insert the round file into the file guide and place it over the chain tooth at the angle indicated by the manufacturer (typically 25-30 degrees).
• Sharpening teeth: Move the file in a smooth motion back and forth along the tooth while keeping the angle constant. Sharpen each tooth in one direction, then turn the chain to sharpen the teeth in the other direction.
• Tine height control: Use the depth gauge to make sure that the teeth have the correct height. Filing teeth that are too high.
• Chain lubrication: Once sharpening is complete, lubricate the chain before refitting it to the chain saw.

Chainsaw accessories improve safety, efficiency and maintenance of the device. Here are some essential accessories:

Safety accessories:

• Helmet with visor: Protects the head and face from wood branches and splinters.
• Cut-resistant gloves: They offer protection against accidental cuts when using the chain saw.
• Cut-resistant trousers: Made of strong materials that prevent the chain from penetrating in case of accidental contact.
• Safety footwear: With reinforced toe cap to protect the feet.

Maintenance tools:

• Sharpening kit: Includes round files, file guides and depth gauges to keep the chain sharp.
• Chain oil: Specifically for chain lubrication, it reduces wear and improves cutting performance.
• Cleaning spray: For cleaning the chain saw from wood, oil and dirt.

Operating accessories:

• Chain tensioner: Tool for adjusting chain tension, ensuring a safe and accurate cut.
• Fuel canister: For mixing and storing the mixture of petrol and two-stroke oil.
• Replacement bar: An additional bar can be used to quickly replace the worn bar.

Transport and storage accessories:

• Chainsaw case: Protects the chain saw during transport and storage, preventing accidental damage.
• Bar sheath: Covers the bar and chain, reducing the risk of accidental cuts during transport.

Routine maintenance of a chain saw is essential to ensure that it functions correctly and to prolong its life. Here are some key tasks:

1. Cleaning the air filter: The air filter must be cleaned regularly to prevent dust and debris from reducing the efficiency of the engine. Remove it and blow it out with compressed air or wash it with soap and water, then let it dry completely before reassembling.
2. Checking and/or replacing the spark plug; Spark plugs must be inspected and cleaned regularly. If they appear worn or damaged, they must be replaced to ensure efficient combustion.
3. Automatic chain lubrication: Use specific chain oil to keep the chain well lubricated. This reduces friction and wear, improving cutting performance.
4. Chain tension: Check the chain tension regularly. A chain that is too loose can jump off the bar, while a chain that is too tight can cause excessive wear.
5. General cleaning; Remove wood and oil from the chain saw after each use. Use a rag or brush to clean the bar, the chain, and the inside of the chain cover.
6. Bar control: Inspect the bar for wear and damage. The bar must be regularly inverted to ensure even wear.

Proper storage of a chainsaw is essential to keep it in good condition and ready for use. Here are some tips for proper storage:

• Clearing: Before storing the chain saw, make sure that it is free of wood, oil and dirt. Thoroughly clean the bar, chain and chainsaw body.
• Draining the fuel: For petrol chainsaws, empty the fuel tank if you plan not to use it for a long period. This prevents deposits from forming which can damage the engine.
• Removing the chain: Remove the chain and bar if you are not going to use the chain saw for a long time. Clean and lubricate the chain before storing it in a dry place.
• Store in a dry place: Store the chain saw in a dry place, away from moisture and weather. Moisture can cause rust and damage to metal components.
• Use of cases: Store the chainsaw in a protective case or container to prevent accidental damage and to keep it clean.
• Periodic checks: Even during storage, periodically check to make sure that the chain saw is in good condition and ready to use when necessary.

The use of a chainsaw requires safety measures to prevent accidents and ensure safe use. Here are some key guidelines:

• Personal Protective Equipment (PPE). Wear a visor helmet to protect the head and face from branches and debris. Use cut-resistant gloves to protect hands from accidental cuts. Wear cut-resistant trousers to protect your legs from contact with the chain. Wear safety shoes with reinforced toe cap to protect your feet.
• Chainsaw inspection: Before each use, check that the chainsaw is in good condition. Check chain tension, tooth sharpness, oil level and air filter cleanliness.
• Working environment: Make sure the working area is clear of obstacles and people. Work on stable and level ground to avoid slips and falls.
• Safe cutting techniques: Use correct cutting techniques to avoid kickback and accidents. Maintain a firm grip on the chain saw with both hands and position yourself securely when cutting.
• Beware of kickback: Avoid cutting with the tip of the bar, which can cause dangerous kickback. Use the chain brake to block the chain immediately in the event of kickback.
• Turning off the chainsaw: Turn off the chainsaw when it is not in use and when moving. Never leave the chainsaw running unattended.

To clean the oil pump of a chainsaw you will need a Phillips or slotted screwdriver, a clean cloth, a soft brush and a solvent to clean the oil pump.

You will then need to follow these steps:

1. Turn off the chainsaw and remove the bar and chain.
2. Using the screwdriver, unscrew the bolts securing the oil pump cover.
3. Carefully remove the cover and check the inside of the pump for any sawdust or dirt.
4. Gently wipe the inside of the pump with a clean cloth and soft brush to remove any residue.
5. Make sure the pump is completely dry before refitting the cover.

Finally, we remind you that for professional chainsaws, we recommend cleaning the oil pump every 25–30 hours of intensive use. For hobby chainsaws, a cleaning every 30–40 hours of use might be sufficient.

To understand how to properly mount a chainsaw, follow these steps:

1. Switch off the chainsaw: Before you start any operation, make sure that the chain saw is completely switched off and the engine is cold.
2. Remove the bar and the old chain: Using the appropriate tools, such as an Allen key or nut spanner, loosen the screws or nuts that hold the chain saw bar in place. Carefully remove the bar and the old chain.
3. Clean the bar: Before fitting the new chain, ensure that the chainsaw bar is clean and free of sawdust residue or dirt. Use a clean cloth or brush to remove any debris.
4. Check the chain tension: Make sure that the chain tensioning device is correctly adjusted to allow the new chain to be installed
5. Install the new chain: Place the new chain on the chain saw bar, making sure that the cutting teeth face the front of the chain saw. Ensure that the chain is correctly aligned with the bar groove.
6. Position the bar and chain: Once the chain is correctly installed on the bar, place the bar and chain on the chain saw, being careful to loop the chain around the pulley and sprocket.
7. Tension the chain: Use the chain tensioning device to adjust the chain tension. Make sure that the chain is correctly tensioned, but not too tight, so that it can work properly during cutting.
8. Fix the bar: Once the chain has been correctly tensioned, securely fasten the bar to the chain saw by tightening the screws or nuts with the appropriate tools.
9. Check the chain tension after fitting the new chain, check the chain tension again and adjust if necessary.

Adjusting the chainsaw carburettor correctly is essential to ensure optimum engine operation, maximizing power and reducing fuel consumption. Improper adjustment can cause starting problems, loss of power and long-term engine damage.

If available, always make sure to follow the manufacturer's instructions and make adjustments with care and precision. Otherwise, you can follow these steps:

1. Identify the adjustment points: Before you start, find the carburettor adjustment points on the chain saw. These may vary by model and manufacturer.
2. Prepare the chainsaw: Make sure the chainsaw is completely switched off and the engine is cold before you start any adjustment of the carburettor.
3. Access the carburettor: Using the appropriate tools, such as an Allen key or screwdriver, remove the carburettor cover to access the adjustment points.
4. Adjust the air/fuel mixture: Using an adjustment screwdriver, find the adjustment screws for the fuel/air mixture on the carburettor. Adjust these screws by turning them clockwise or anticlockwise gently until you have obtained the correct mixture.
5. Check the mixture: Start the chain saw and let it run for a few minutes. Listen to the sound of the engine and observe the colour of the exhaust smoke. A correct air/fuel mixture should produce a smooth sound and light or bluish exhaust smoke.
6. Adjust the accelerator: If necessary, also adjust the throttle to ensure smooth and immediate response when operated.
7. Carry out a practical test: After adjusting the carburettor, carry out a practical test by cutting wood or other cutting operations. Test the chainsaw in different conditions and make sure it responds correctly to the inputs.
8. Make any further adjustments: If you notice problems during the practical test, such as a lack of acceleration or erratic operation, further carburettor adjustments may be necessary.

My chainsaw, when cold, let's say it starts without too many problems... then after 5 minutes of use, if I switch it off, it won't start again until it cools down a bit... which is very annoying and I lose 15 minutes every time. Have you experienced and fixed this issue yet?

Answer:
- Giulio 2020-06-11
I would advise you to change the spark plug that came out, with a better quality one, I also experienced this problem at the beginning, I immediately realised that the problem was the spark plug, when I took it apart it was almost burnt out, after changing it with a better quality one, the problem did not recur

Question:
- Danilo 2018-03-26
At what percentage do you use the mixture?

Answer:
- Luigi 2018-03-26
the mixture for the chain saw must be made at 2%. As far as the run-in phase is concerned, we suggest a mixture even at 2.5 per cent.

Question:
- Edi 2020-05-28
Hello, I bought the chainsaw, it works, but I have trouble penetrating and cutting branches from a couple of centimetres, why? Is there anything in particular to be done on the chain?

Answer:
- Gabriele 2020-05-29
Good morning, Make sure you have fitted the chain correctly, respecting the direction in which the links are cut. With the clutch unlocked, and the machine switched off, the chain must be able to turn, pushed with a hand wearing a glove. However, keep in mind that where cutting is difficult (you can tell by the energy you put into pushing), you need to sharpen the links. I do this with a round file of a suitable calibre to get into the small blades, maintaining the right angle and working first one way and then the other. Finally, if you accelerate the machine with the blade tilted over a sheet, you must see the oil marking the sheet. Before storing it, clean it well, also disassembling the blade. It's an operation that takes a few minutes, but you end up with a machine that is always in perfect condition. I am very satisfied. If you need anything else, just ask.

- Angelo 2020-05-29
surely you have mounted the chain backwards. Consider that I bought the chainsaw more than a year ago and have never had such problems. The only small problem I have encountered is the high altitude carburettor, as the installed carburettor does not have screws for adjustment.

- Alberto 2020-06-01
I also bought a chainsaw a few months ago. The only small problem I have encountered is the carburation at high altitude, as the fitted carburettor has no adjustment screws. However, I think this is quite normal for a small pruning tool. If anything, you can try to sharpen the blade by lowering the guide teeth between the cutting teeth with the file, which regulate the penetration of the blade. They must be 1-2 mm lower than the top line of the cutting teeth. If the difference is small the blade will not drop and spin, if it is too much it will eat too much wood, and it will lock up as there is not enough engine force to cut. I hope I was helpful

Question:
- Ivano 2020-08-11
as already written a few weeks ago, I received the chainsaw ordered in a short time. I've only had a chance to try it out three weeks after purchase, and I wanted to ask a question -assuming I've just done a few test cuts-: is it normal for there to be a lot of chain oil leaking out? If not, can you advise me what to do, considering that I have already adjusted the idle screw. Thank you.

Answer:
- Andrea 2020-08-12
It doesn't happen to me, if you fill up with oil and after a day, not using it, it is empty then there is a problem. Some oil spillage is normal, especially if it is new and if you have used it without cutting wood or very little. Use it a little and see... a full tank of petrol and a full tank of oil, the consumption of the two elements must be equal. When you run out of petrol you should also run out of oil, if one runs out before the other it is not regular. hello good work.
