Chainsaw maintenance
1. If the chain saw appears to be refueling and stalling, working less vigorously, or overheating the heater, it is usually the filter. Therefore, before working, it is necessary to check the filter. A clean and qualified filter is aimed at the sunlight and should be clear and bright, otherwise it is unqualified. If the filter of the chain saw is not clean enough, it should be washed with hot soapy water and dried. A clean filter can ensure the normal use of the chainsaw.
2. When the saw teeth of the chain saw become unsharp, you can use a special file to rest the teeth of the saw chain to ensure the sharpness of the saw teeth. At this time, it should be noted that when using the file to file, it should be filed in the direction of the cutting teeth, not in the opposite direction. At the same time, the angle between the file and the chain saw chain should not be too large, and it is appropriate to be 30 degrees.
3. Before using the chain saw, the chain saw chain oil should be added. The advantage of this is that it can provide lubrication for the chain saw and reduce the frictional heat between the chain saw chain and the chain saw guide plate. The guide plate provides protection and also protects the chainsaw chain from premature scrapping.
4. After the use of the chain saw, the chain saw should also be maintained, so that the work efficiency can be guaranteed when the chain saw is used next time. The first is to remove the impurities in the oil inlet hole at the root of the chain saw guide plate and the guide plate groove to ensure the smoothness of the oil inlet hole. Secondly, the debris in the guide plate head should also be cleared, and a few drops of oil should be added.
Why does the chainsaw not start?
1. Check the oil circuit and circuit to see if the oil filter is blocked, if the carburetor is pumping oil normally, if the spark plug has electricity, remove the spark plug and put the top on the metal, and you can see the spark plug by pulling the machine Is there any electricity.
2. Remove the air filter and check whether the air filter is clean.
3. Remove the carburetor, then drop some oil into the cylinder and start the machine a few times. If not, you have to wash the carburetor or replace it, and finally check the cylinder. Teach you a way to maintain the machine. If the machine is not used for a long time in the future, the oil in the fuel tank must be drained. Start the machine to burn out the oil in the carburetor and cylinder. In order to avoid residual oil from clogging the carburetor, usually clean the air filter more often, and the lubricating oil must be better lubricated.
What causes the chainsaw to stall?
In fact, there are several situations in which the fire cannot be pulled. Be clear about what causes the pull to fail to catch fire. It will be much easier to understand these troubleshooting and solutions.
First of all, let’s talk about the basic maintenance ideas of chain saws: understand the symptoms of the customer’s product use, and carry out further inspection and judgment from three aspects according to the customer’s description: oil circuit, circuit, cylinder.
The usage and symptoms include: the last time of use, the environment and the condition of use at that time,
The oil circuit includes: carburetor, gasoline filter, oil pipe, balancer, Oil pipe intake pipe, etc.
The circuit includes: magnetic flywheel igniter, coil/high voltage, spark plug.
Cylinders: Pistons, piston rings, cylinders.
Next comes the hands-on inspection and maintenance steps.
The first step: We will manually pull the chain saw to see the overall operation. At this time, we can judge according to the obtained information: whether there is a stuck cylinder (experienced can directly judge whether there is compression and Pull the cylinder), whether there is abnormal noise (it can be judged whether the magnetic flywheel and crankshaft are damaged), whether there is any problem with the starting assembly. And replace or maintain parts according to relevant conditions.
The second step: judge the circuit. Remove the spark plug (the spark plug is under the air filter cover), and check whether the spark plug has carbon deposits and whether the contact is normal. Make the discharge part of the spark plug contact the cylinder or the conductive part of the crankcase, and pull the chain saw. At this time, you can check the circuit, such as whether there is electricity, the size of the electricity and whether the discharge interval is stable. This step can check whether the spark plug, coil and igniter are normal.
Step 3: Block the outside of the spark plug of the cylinder with your fingers and pull the pull disc to check whether the cylinder is pulling the cylinder. Or remove the muffler, and see if the piston has any pull marks from the cylinder muffler.
Step 4: Check the oil circuit. Remove the carburetor and clean it, and adjust the carburetor pointer appropriately according to the situation. Unscrew the fuel cap and check the fuel filter. And check the oil pipe, intake pipe, etc. for damage.
Under normal circumstances, replacing or maintaining the faulty chain saw accessory part will solve the problem.
In addition, oil seal damage, negative pressure pipe (balance air pipe), magnetic flywheel and crankshaft, crankcase, balancer problems are uncommon, and can only be considered when the above steps cannot solve the problem.
Chain saw use and maintenance Chain saw oil distribution
The chain saw is a two-stroke power, and attention should be paid to the power and cutting tools in use to ensure the normal use of the machine: the engine is a two-stroke engine, and the fuel used is Gasoline and engine oil mixed oil, the mixed oil ratio is: air-cooled two-stroke special oil JASO FC grade: gasoline = 1:50 (air-cooled two-stroke special oil JASO FB grade: gasoline = 1:25).
The gasoline should be No. 90 or higher, and the oil should be air-cooled two-stroke engine oil. The symbol is 2T. It is necessary to use brand-name special engine oil. It is strictly forbidden to use four-stroke engine oil or water-cooled two-stroke engine oil. It is recommended that the new machine be equipped with 1:40 (JASO FB grade oil 1:20) in the first 30 hours, and 1:50 (JASO FB grade oil 1:25) according to the normal ratio after 30 hours. It is absolutely not allowed to exceed 1:50 ( Ordinary oil 1:25), otherwise the concentration will be too thin, which will cause the machine to pull the cylinder.
Please dispense oil strictly according to the oil dispenser attached to the machine, and do not dispense oil at will. It is best to use the mixed oil now, and it is strictly forbidden to use the mixed oil that has been set for a long time; before the machine works, run it at low speed for a few minutes to see if the saw chain oil is lubricated to form an oil line, and then work. When the machine is working, put the accelerator on the high speed use. After working a tank of oil, you should rest for 10 minutes. After each work, clean the loose gasket of the machine to ensure heat dissipation; remove the spark plug every 25 hours, use a wire brush to remove the dust on the electrode, and adjust the electrode gap to 0.6 -0.7mm is good; the air filter removes dust every 25 hours of use, and the dust should be more frequent. The cleaning of the foam filter element is to use gasoline or washing liquid and water to clean, squeeze to dry, then soak in the oil, squeeze out the excess oil to install.
Every 50 hours of muffler use, remove the muffler and clean the carbon deposits on the exhaust port and muffler outlet. The fuel filter (suction head) removes impurities every 25 hours.
When using a new machine, you should pay attention to the tightness of the saw chain, so that the saw chain can be pushed to rotate. It is advisable to use a hand-held saw chain with the guide teeth parallel to the guide plate. After a few minutes of use, pay attention to tension again. Tighten the saw chain.
Before using safe work, people or animals are not allowed to move around within 20 meters. Be sure to check the grass for debris such as angle iron, stones, etc., and remove the debris on the grass.
Chainsaw storage
When storing, the body must be cleaned, the mixed fuel must be discharged, and the fuel in the carburetor must be burned; 3 times, install the spark plug.
