device with chain saws Chainsaws
"Ural", "Friendship" and "Friendship-Altai" consist of such basicassemblies, engine, clutch, gear, sawing machine, frame with handles and controls the starter.
main nodes of the engine acts cylinder crankcase, crank
The clutch includes drive plate, the rim of which there are two iron rings cut and driven plate with a rim in the form of the letter "G".
gearbox housing is presented and two bevel gears: slave and master, which are mounted on ball bearings in the housing.The frame consists of a rack and a steering arm, which are connected anti-vibration device that includes a hinge and a spring.
Cutting equipment represented the saw chain and bar.The power supply system includes components such as the fuel tank, faucet and carburetor.Supply of fuel from the fuel tank to the carburetor when the cock is open for a gasoline held by gravity.Starting the engine produces removable starter, consisting of a pin, brake ratchet bolts, roller, drum corps, cable, springs, handles and plugs.
Working with a chainsaw
All customers with chain saws want your purchase as soon as possible to try in real conditions.Remember that it is not necessary to run a chainsaw without saw sets of preset and tires, chain and sprockets - the driving wheel.There is a risk that the clutch may burn at constant shutter button is pressed.
Just before the intense work necessary to tire, sprocket and chain got used to each other.And you have to break in the engine itself, thus emptying the entire fuel tank and putting a little effort.BREAK-saws Do not idle, because it can cause increased engine wear.
turn the ignition switch to the operating position before starting the chainsaw, gasoline pump up the carburetor, pull out the choke and pull strong jerk snatch starter.If you spin the engine vyalovato snatch starter, then it increases the likelihood of casting candles and attempt to start the engine will be reduced to zero.This candle is necessary to unscrew and warm to all the steam evaporated fuel mixture under heat.
highlights work in the operating instructions of the Ural chain saws, friendship, Goodluck and others are as follows:
- chainsaw must be held with both hands, grasp the handle with all fingers chainsaw.The thumb of the left hand is located under the front handle.
- working with a chainsaw, you must stand on the side of the tool, right behind him you can not stand.
- Sawing decided to use the lower and upper edge of the chainsaw.If you prefer to cut the upper edge, the chainsaw in the direction goes to you, otherwise - from you.
- If possible, keep your back flat when working with a chainsaw.Preferably the legs bent at the knees.To maintain balance, it is desirable to arrange the wider foot.
- very dangerous to move a running chainsaw.In transitions between places cutting is necessary to turn off the chainsaw for safety and to put on the brakes.
- better to begin to cut the edge of the tire, which is closer to the body with chain saws.
- If you plan to use your chainsaw often, it is advisable to read the instruction manual Husqvarna chainsaw, the friendship, the Urals, etc.and buy special protective clothing: protective jacket with ventilation, Helmet, special pants with provided protection cuts saws, protective boots with steel plates and strong gloves.
two-stroke internal combustion engines to themselves require special attention during the changing seasons of operation.If you use with chain saws with a temperature outside is below 0 degrees, it is necessary to warm up the carburetor itself as the fuel mixture is able to crystallize, increasing the viscosity of the mixture.Saw itself in this case has to adapt to such a temperature regime.
If the saw is not kept in a heated building that is less than zero degrees Celsius, it is undesirable to enter directly into the room where the temperature rises above 0 ° C, as otherwise condensation may form, which entailsdisruptions in the functioning of the equipment and other negative consequences.
All saws mounted 2-stroke internal combustion engines.There are two tank: the fuel mixture and oil.Fuel tank in the normal case is of the order of 0.3-1 liter, and a piece of plate to the oil, usually less than 2 times.These proportions lead to the fact that after the fuel tank has ended the mixture is almost the same and the oil consumed.
Chainsaw with two-stroke engine according to the instruction manual chainsaw friendship, Ural, Goodluck, calm, hustkvarna decided to fill with a mixture instead of petrol, which is a oil and gas in certain proportions.The process of preparing the fuel mixture for these engines is very important, so do not neglect the requirements of manufacturers in its manufacture.The two-stroke engine for lubricating friction, unlike four-cycle, occurs through the fuel mixture, and in which there is a certain portion of oil.
in two-stroke engines can not be used system oil pumps, oil is added to gasoline made.Before pouring the fuel mixture close it is recommended Shake.For chain saws are usually prepared fuel mixture of oil and gasoline.It will take 40 milliliters of oil and 1,000 milliliters of gasoline.The mixture, mix thoroughly before fill the fuel tank.
When making mixes for chainsaw use is recommended only genuine oil.The proposed oil grade to be used to prepare the mixture specified in the instructions.It is forbidden to be used for low-speed two-stroke engine oil.
Gasoline is best not to use leaded.The octane number of the gasoline must be not less than 90. The finished fuel mixture must be stored no more than 1.5 months.The use of the old mixture is bound to cause the output of the engine failure.
for chain lubrication can be used pure oil or any specific brand.For domestic chainsaw approach the 76th petrol to import better to take 92 minutes or more.Can not be used for chain lubrication waste oil, or oil with low viscosity - spindles and industrial transformers.Before starting the chainsaw you need to remove it from the place where the filling, in order to avoid ignition.
before using any imported chainsaws required her preconditioning.It is on the one hand is needed to prolong engine life, because the moving parts in the running-in period should be earned extra initially to each other.In addition, during a run, you can acquire certain skills with chain saw.This is important for those users who first read the operating instructions for the chainsaw Makita, friendship, Ural, calm and work with a chainsaw.
chainsaw break-in must be carried out with a minimum load on the engine in cyclic operation: sawing lasts 1-1.5 minutes and then 15-20 seconds of idling.The maximum capacity of the engine will acquire after working ten full tank refills.You can not run in the engine idling because the formation of a large amount of soot provokes occurrence of piston rings or exit spark plug failure.
Preparation chainsaw to work
Check chainsaw to start on the chain tension, which is to be adjusted, the chain slack is unacceptable.Poor chain tension is capable of faster tire wear and laid a star, greatly increases the load on the chain saw body and prematurely withdraw shock failure.
chain saws should not touch with a hard object, activate the chain brake, move the brake lever away from you to the circuit ahead of time does not rotate.Pull the lever valve, so you can do when the engine is cold.Pass in the rear handle sock feet.Pull the starter cord until pulling the handle until the power saw not sneeze.
Then Start the saw and move to the operating position the choke.Click on the gas and turn the chainsaw in idling.Pull the brake lever to achieve its former position.Now, the chainsaw is ready to work!
Before you start, check the brake tool.Next is to set the saw on a flat, hard surface and push the throttle.Do not release the handle chainsaws, click on the knob and activate the brake.The brake shall be considered in the order when the saw chain to stop.
Before you start the chainsaw, you should definitely check the oil in the tank for the chain.In the absence of lubrication at high speeds may occur problems with chain and bar.Check the lubricant can in the process.When operating at considerable speed chainsaw should be sent to the bus on a clean paper.If the grease is supplied normally, it will be seen on a sheet strip of oil.
How to fell trees
Immediately before felling a tree you need to read and other power saws and determine where it falls.Look at the number of branches, and where the main face, should take into account the wind direction and the natural inclination of the trunk.To bring down the trunk must be in the direction in which it is more convenient to fall.Cut away right in front of the lower branches of the tree felling.
depending on the thickness of the wood and other features distinguish several methods for felling, the best solution is chosen only by professional loggers.Before felling a tree is to make sure that it does not hurt anything since the fall.
Become the trunk of a fallen tree on the left, cut the branches with it, move from the bottom of the barrel.Try the nose of the saw is not used, work slowly.Lean chainsaw to the thigh or the trunk of the tree and all parts of the tire use for cutting.Put to one side with chain saw, all the weight on the trunk, cut down branches from the top of the barrel.When the top and sides will be cut off branches, the trunk can be turned and saw off the rest.
Thus remember that at a certain position of the tree, which is based on one branch, the trunk can move or roll when cutting.When thick and large branches is necessary to saw off part by part, moving from its end.If the branch is too thick, it may require filing with multiple parties.
When you sawed off all the branches from the trunk, you can start sawing the trunk - his bucking.Bucking need to start from the trunk to the top.If the trunk is on an incline, then the bucking is prohibited to stand below the tree trunk.If stuck with chain saws in the trunk, then you need to immediately get it.Stop the engine and tilt the trunk, until you can pull the saw.
care chainsaw Petrol motive-powered saws
must be kept under cover or in open spaces.Before setting the tool for storage, it should be cleaned of sawdust and dirt to drain the fuel from the tank, remove the chain and put it in the oil.Public places that are exposed to corrosion, lubricate the oil layer.Chainsaws for long-term storage should be preserved.
After working with chain saws prodelyvat you must follow these steps:
- Check the tension with chain saws and grease.If oil is over, it is necessary to refill the tank and tighten the chain if it is loose.Give a little rest and cool instrument, then it should be filled with petrol saw.
- Do not forget to check the air filter, which can become clogged during the chip and sawdust.Therefore, it must be time to take pictures, blown and washed.If necessary, clean the filter is dirt.
- Once each hour when the chainsaw work, you need to lubricate the driven sprocket tires and dipped in warm oil.
- After 25 hours of operation, from the windows of the cylinder, the combustion chamber, the piston grooves, the bottom of the piston rings and remove the dust.
You should carefully read the instructions about the operation of chainsaws stihl, friendship, calm, the Urals, especially the sections that deal with a cold and a hot engine.The principle is the same engine run all saws.The differences are only in the placement of controls with chain saw - the choke lever and stop button.
Run cold engine must be this way:
- turn the switch to "on" position;
- pull the choke lever to the full;
- pull the starter cord handle several times before the first outbreak in the motor fuel;
- move to the middle position choke lever (choke open position increased idling is included);
- repeat the starting procedure;
- after starting the engine, press and immediately release the throttle trigger - the working position automatically go choke.
Run the engine warm so you need:
- move the switch to the "ON";
- pull the choke lever to the full, then move to the middle position, or do not touch and leave the position of the traditional idling;
- make the engine start-up procedure;
- when in idle position increased the choke lever when starting the engine, press the throttle trigger and let him go;
- stop the engine can be made by transfer to the 0 (off) switch.
with combined controls
start a cold engine can be in the following sequence:
- simultaneously press the lever throttle trigger and turn the shaft of the control valve to the lowest position, the choke valve in this case is completely closed;
- pull the starter cord handle several times before the first outbreak in the motor fuel;
- move to the middle position the control shaft;
- repeat the starting procedure of the engine;
- after starting the engine, press and release the throttle trigger, the control shaft in this case goes automatically to the working position I.
hot condition according to the instruction manual chainsaw calm and any other instrument with chain made so:
- shaftcontrol to a position normal idling;
- make engine start;
- press and release the throttle trigger in finding the large shaft in position idle.
- is strictly forbidden to work with collimation and faults with chain saw.
- When starting the engine, you can not wire wound on his arm.
