How to work a chainsaw for beginners

Easy chainsaw start

Why you need a fuel precharge pump?When you press the pump part of the fuel pre-pump, the fuel mixture is pumped and fills the carburetor. A cold engine will start faster. (Fuel precharge pump installed on Patriot Garden 2512; 3816; 3818; 5518).

What is the difference between a nylon and felt air filter?The nylon filter is mostly reusable and easy to clean and wash when dirty, but can be damaged if you accidentally hit it with coarse shavings. The felt filter is more resistant to mechanical damage, but cleaning it when dirty does not always get the desired results. (All Patriot Garden models have a nylon air filter).

What the Number of Cams on the Clutch Affects? cams results in a stronger grip, minimizing slippage. Load on clutch cup is more uniform. (All Patriot Garden models except the 2512 have a 3-jaw clutch).

Why do you need the vibration guard??When you are sawing, there is a small amount of vibration when the engine is running and the saw chain is in contact with the wood. A vibration damping system helps to reduce the operator’s perception of these vibrations considerably. (All Patriot Garden models are equipped with vibration protection).

What is an adjustable oil pump?The oil pump setting affects the amount of lubricant applied to the saw bar. When using differently sized guide bars on a chainsaw, it is necessary to optimize and adjust the lubricant flow, i.e.The longer the bar is, the more lubrication is needed. When cutting different types of wood it is also necessary to adjust the amount of lubricant. (All Patriot Garden models except the 5518 have an adjustable oil pump).

Why is the small hole in the tip of the bar necessary??A hole is provided for lubricating the idler sprocket roller bearings. Т.к. This makes the sawing operation very stressful, so it is a good idea to lubricate the motor with a grease gun before sawing. Roller bearings are more likely to seize in the absence of lubrication. (All Patriot Garden saw chain is equipped with a lubrication hole).

Why the chain brake is needed?There is a 90° section at the top of the bar tip that triggers the chain to bounce right back at the operator when sawing. To prevent injuries, the flywheel brake automatically engages with the right hand wrist during rebound. The mechanism responds and the chain comes to a stop immediately. (All Patriot Garden models are equipped with a chain brake).

What’s the advantage of a chromed cylinder motor??Chromium plating is used to increase engine life, i.e.chrome is a very durable material, resistant to high temperatures, has good friction properties. Chrome-coated cylinders are used extensively in power tools that are designed for professional applications. (All Patriot Garden models have chrome cylinders).

What is the difference between a single and two piston rings in engine design?Single-ring engines have faster acceleration and better fuel economy. Cylinder wear is slower due to smaller contact area. But these engines are very sensitive to fuel quality. Engines with two piston rings have lower acceleration and stroke rates than engines with one piston ring. contact area and higher friction causes faster cylinder wear. Sensitivity to fuel quality is lower. (All Patriot Garden engines except 2512; 3816; 3818 are equipped with two piston rings).

What is “Easy start”??chain saws that are equipped with an “easy-start” starter system have a special mechanism with two cocking springs in their construction. Much less force is needed to pull the starter rope. The engine can be started much more easily. (Patriot Garden 3816; 3818; 4016; 4018 models have an “easy start” system).

Getting ready to run

The first thing you need to do when working with a chainsaw is to assemble it. The assembly diagram for the different models is almost the same. Saw bar and chain are mounted on the saw and the chain is tensioned.

The chain is properly tensioned when it is not sagging on the bar and can be easily turned by hand. If you have to use too much force to turn the chain, it has become overtightened and you should loosen it a little.

Next, check the sharpening of the chain by visually inspecting the cutting edge of each working tooth. Edges must be even without dents and nicks.

The next step is to refuel the chainsaw. The fuel mixture is prepared in a certain proportion, which you can read in the user manual that comes with the saw. As a rule the fuel mix is diluted in the proportion 1:50, i.e. 20 grams of two-stroke oil should be added to one liter of gasoline AI-92.

Important: When pouring fuel and oil for chain lubrication into the tanks, you must be extremely careful not to mix up. If you pour oil into the fuel mixture tank, the chainsaw will not work. To restore performance, you will need to flush the fuel tank with gasoline, as well as clean the fuel line and carburetor, which is quite difficult.

Features of domestic chainsaws

The domestic tool has certain design features. In order to operate them properly, it is necessary to learn the construction of chainsaws. The most common tools in this category are the “Druzhba”, “Druzhba-Altai” and “Ural”. They have been on the market for a long time.

To understand how to use a chainsaw “Druzhba” and other brands, it is necessary to consider their device. The equipment has an engine and a clutch, there is also a gearbox. A saw unit is obligatory. To be able to control the starter, special design elements are provided.

Power system has a gas tank, carburetor and valve. Gravity fuel flows through the gasoline line when the valve is open into the carburetor. Removable starter starts the engine. All of these systems must work properly to ensure the proper functioning of the equipment.

Working with a chainsaw can be dangerous and strenuous. Never start without familiarizing yourself with specific safety requirements and operating procedures.

• For a beginner, a type of saw with a set of teeth will be more practical than a cutting blade, so this article will discuss a chain saw. The length of the saw should be at least one-third the diameter of the tree.

• Generally the horsepower and horsepower is the same as the chain length and is set at the factory. A well-tuned engine and sharp blade will allow you to cut quickly, easily and accurately, resulting in a safer.

Review the area you plan to work in before refueling the saw. It is better to do it indoors for better safety. This means looking out for overhead power lines and rough terrain, nearby cars and buildings, and a safe place to protect the saw operator from falling trees and branches.

• Felling is the process of felling trees.
• Limbing is the removal of the ends from a tree before or after it is cut down.
• Trimming (when using a chain saw). Refers to pruning limbs and branches (unless you are using a saw, this can be similar to shaping a bush, will not be discussed here).
• Barking: cutting logs into pieces of the right length, such as logs for a fireplace.

Take a look at your chainsaw. If you’re getting ready to start a chainsaw you’ve already chosen, it needs to be right for your project.

Fill the tank with the right fuel/blend, which is usually made from one gallon of gasoline and 4-6 ounces (110-170 grams.) Two-stroke motor oil. Since chainsaws have a two-stroke engine, they do not support other lubricants, and fuel will burn quickly if the correct mixture is not used.

Check for safety. Make sure the chain is in place, properly tensioned, and does not move when the chain brake is applied. Check that the air filter is properly installed and that the pressure nuts on the face plate are tight.

Note that there are two filter caps on your saw, next to the throttle handle. Caps can be labeled, usually the larger cap will be for fuel and the smaller one for oil. Fill the lubricant reservoir, check that both caps are tight, and place the saw on a level surface. This is especially important for spinning a very large saw, because the blade will start spinning as soon as the saw starts up and gains momentum.

Many newer models have an ignition button on the carburetor, if yours has one, press it 3 or 4 times. If your saw is equipped with a choke, put it in the closed position. Engage the chain brake. Turn on the saw, it may be a toggle switch, roller or switch, depending on the model. Pull starter rope sharply to start engine. If the engine tries but fails to start, release the throttle and pull again. Usually, in a tuned saw, it takes 4 or 5 tries.

When the saw is running at idle speed, the blade should not move or twist. Let’s think you’ve picked the right piece of wood or branch with the right place to cut. Put the cutter in the position of the cut you want to make, turn off the chain brake, squeeze the throttle all the way open, and lean the cutter against the wood. Do not speed up the cutter, it should only cut under its own weight or moderate pressure. Keep the saw on full throttle while you cut, loosen the throttle only when you are about to complete the cut in the opposite side of the log.

How to use a chain saw

Today’s chain saws come in three big groups: residential, professional and semi-professional. Household machines are light and not very powerful. Such power saws will be useful in the household, in the countryside for cutting firewood, pruning branches in the garden. The lifespan of a home saw is limited to a few hours of operation per month.

Use semi-professional tools to fell trees, do construction work, make repairs. The chainsaws are used 6-8 hours a day, unlike powerful professional modifications that can work in intensive mode for up to 14-16 hours daily, and uninterruptedly for at least 8 hours.

It is a good idea to use a chainsaw after you have read the factory instruction manual. The instruction manual of your particular tool is the best place to tell you what to do. It is especially important to learn how to work safely for first-time users.

Therefore, you should not rush with the first start-up, it is advisable to take time to study the device of the chainsaw, learn for sure what materials can be sawn, how to quickly eliminate possible breakdowns and malfunctions, how to avoid failures in work, prevent injury-prone situations.

Preparation, first start, running-in of the saw

As a standard equipment of a chainsaw there is a set of chain-saw. guide bar with a chain, a fuel mixture container, the manufacturer’s instruction, tools, sometimes there is a brand oil in the set.

The chainsaw is powered by a two-stroke engine that consumes the fuel mixture. Depending on the manufacturer, the oil to gasoline ratio may be different, so always follow the instructions.

The normal proportion is 1:50 (oil:gasoline). Gasoline AI-95 is used for expensive chainsaws, other models use AI-92. Brands of oil are specified by the manufacturer. original or corresponding analogues. Prepared mixture should be poured into a fuel tank up to a proper mark. In new models of chainsaws oil and fuel tank are located next to each other, in order not to confuse them, near the neck of the fuel tank there is a gasoline tank symbol, and next to the oil tank. a drop symbol.

The oil reservoir is filled with oil whose grade and viscosity depend on the conditions and use of the chain. It is recommended to comply with the manufacturer’s requirements for the oils used, because the efficiency and longevity of the chain depends on the quality of chain lubrication. Never use any substitutes, homemade lubes or low-quality batches for chain lubrication.

Starting a chain saw

Before use, check that the chain is properly tensioned, has no slack, and does not slip over the bar. The chain brake must be engaged. Start the machine on level ground: right foot is on the rear handle, left hand holds the front handle. When starting the engine in cold weather, pull the starter grip after opening the throttle.

After a flash the choke is closed and the starter grip is pulled out with a sharp movement. Then, after disconnecting the chain brake, warm the equipment by pressing the gas. To check the oil flow, hold the saw in front of you from the weight of the paper and let it drop, check if the oil starts to flow. If the engine is hot, do not open the throttle when starting the chainsaw.

How to Trigger Your Saw Properly

When learning how to use a chainsaw, you should pay attention to the running-in procedure. The level of manufacturing of modern chainsaws is quite high, they do not need a special running-in. The only condition is the need to sustain the first time cyclic mode at a gentle pace: sawing 1-1.5 minutes / idling for 10-15 seconds. After using 8-10 full fills of the fuel tank, the motor reaches full power.

Running in the engine only at idle speed, as it was practiced before with other chainsaw models, leads to the formation of carbon deposits due to incomplete oil combustion, which subsequently provokes serious damage to the cylinder-piston group.

Service for chain saw

Before operating the saw, check the amount of fuel each time. Periodically check the degree of filling of the oil tank, it is very important not to let the oil level drop. Check tension of chain and sharpness of sharpening before sawing. Monthly lubrication of the bar bearings.

Clean sawdust and shavings from the saw when you finish work. Clean air filter. best of all is a nylon or foam filter, not a disposable felt one. The air filter should be cleaned if you notice that the engine starts to run rough or starts to choke while you’re sawing.

Wipe down the cooling fins, air vents. Don’t forget to clean brake band. Use up the fuel mixture you have prepared over a period of 3 to 4 weeks. It must be remembered that a good chain saw care has a big impact on the tool’s longevity, efficiency, absence of failures and malfunctions.

Reverse the bar periodically for even wear and tear. Experienced chainsaw owners, in the recommendations on how to use a chainsaw, advise to have three chains, which ensures even wear of the driving gear. You can not cut with a blunt chain, it is dangerous, it increases the load on the engine, and as a result the saw cuts absolutely poorly. crooked or goes to one side. If you don’t use the saw for a long time, you have to loosen the tension in the chain.

How to cut a forest correctly

This is a very demanding job. Before you start using the chainsaw you first have to determine the size and height of the trees, the fall direction of the tree, the wind speed and strength and the characteristics of the surrounding area. To reduce the risk of bodily injury, you should familiarize yourself with the operating manual, make the top and bottom cuts, and use the main bar properly.

When felling timber, the following factors should be taken into particular consideration in order to avoid problems:

How to cut structural timber

No construction can do without a chainsaw. This tool can be used to quickly and easily cut a board to size and trim the edges of beams, joists and other scaffolding.

The chain saw makes it possible to make cuts on the spot, and the cutting can be done very quickly with minimal effort.

Provided that it is necessary to cut a board with high accuracy, the master cannot do without a ruler, a tape measure, an angle and a simple pencil. When directly cutting marked boards it is necessary to make allowance for the width of the saw chain. That is, the line for the cutting trimmer must run a little higher, about 5 (mm), than the marking line.

Principles of wood sawing

How to saw with a chainsaw correctly? This should be at full throttle. Always cut with the bar closer to the body of the tool. Note that a different cutting method should be used for each material

Branch trimming

If you are going to cut branches from a fallen tree, stand to the left of the trunk and start at the bottom. The movements should be carried out slowly. The cutting is done with the nose of the bar, with the upper and lower blades of the chain. Thick, difficult to handle branches are sawn in several steps. from the end to the base of the trunk. Be aware of the fact that without support the trunk is likely to roll, so make sure it is stable before you continue sawing.

Cutting the tree into several parts

When you have cut all the branches off the trunk, go on to the next step. crosscutting. Be careful because the barrel can roll away from you because of the vigorous jerking of the saw. If the tool gets stuck in a tree, don’t try to pull it out. Simply turn off the chainsaw engine and tilt the barrel slightly

Felling trees

Never felling trees by yourself. Have at least one helper with you in case of an emergency. Before you make the felling notch, check the tree trunk carefully for any dry branches that might fall on you. Make sure that neighboring trees do not get in the way. Then stand to the right of the tree. Try to hold the tool from the side. This will noticeably reduce the strain on your spine and arms. The process itself can be divided into the felling and the basic felling. Start the work at a forty-five degree angle, one-quarter of the way down the tree. This course of action ensures that the tree will fall in the right direction. Then start making the basic felling cut. When the tree falls down, try to remove the tool quickly. You can see how a chainsaw works in the video. Chances are, looking at a live performance will help you learn the process faster.

Three classes of machines

Currently on the Russian market you can find a large number of chainsaws, which can be divided into three classes:

• The first class includes simple household devices, which are designed for uncomplicated household needs. Such chainsaws are often low-powered, but they perform all their jobs very well. You can use this chain saw to cut down a rotten tree or cut firewood for the sauna. Despite the fact that the functionality of such saws is minimal, it is easily compensated by the ergonomic controls and their low weight.
• The second class includes the so-called semi-professional models, which can perform almost any work. from repair and construction tasks and up to felling trees. But such models have a big disadvantage. they are not designed for 8-10 hours a day. This is why they are called semi-professional. often than not loggers use these saws as pruners.
• The third class includes professional saws, which are a great solution for people who specialize in logging. These machines can be used for 10-15 hours a day and operate for 8-10 hours without interruption.

The main points of the preparatory work are set out in this instruction video on the example of a two-stroke gasoline saw with a cutting depth of up to 50 cm, a tank volume of 750 ml, designed for about an hour of active work.

• First, fill the tank with fuel mixture and, if necessary, lubricating oil.
• Check that the trigger and two levers on the saw work properly.
• Pull throttle lever before starting engine.
• Slide the chain brake handle, which is responsible for stopping the chain in case of emergency, slightly to the rear.
• Be sure to check the tension in the chain. Sagging is absolutely unacceptable. To remedy this, loosen the two screws on the saw body, tension the chain with a screwdriver, and tighten the screws again.
• Lock the tool while you are taking it to the site.

The chainsaw is ready for operation, but before you activate it don’t forget to wear the basic protective equipment: coveralls, boots, gloves and hard hat with ear protectors and ear protectors.

On the jobsite, disengage the safety interlock. Pull the starter motor briskly to start the saw.

In order to cut the tree without much effort, cut a wedge-shaped piece about halfway down the trunk. First make the cut by holding the blade at a downward angle and then at an upward angle. After cutting from the back side, the tree will give way and fall toward the wedge.

Before you make the cut, make sure you securely stow the tree trunk. If it is not possible to cut all limbs at once, first clean one half of the log, then turn the log over and cut the remaining limbs on the other side.

It’s a good idea to saw too thick logs into billets in two cuts: first, cut through the middle of the log from above, then position the chainsaw underneath and finish the cut.

Beware: Never allow the saw blade to come into contact with the ground. This can lead to serious damage to the tool.

Observing the recommended guidelines when using a chainsaw will effectively extend the uptime of the tool and, most importantly, protect you from accidental injury when working with it.
