Chain saw is the most widely used in many machine products, one of the most frequently used power tools.Because it comes with very sharp serrated teeth designed for cutting wood, so when their jobs, need to adoptmore stringent safety precautions. Any non-standard operations, without timely maintenance will form acertain security risks, need attention. The company's engineers to develop a series of chainsaw use andmaintenance techniques and considerations, to share with you.
Always ensure the saw chain lubrication
Lubrication of the saw chain and guide for chain saw use of the term, and its importance. Engineers said thatthe saw chain you must always have a small amount of lubricant out, do not work the saw chain, nolubrication. If the saw chain turn the cutting tool will soon be corrupted and cannot be repaired. So, beforestarting work, remember to check the saw chain lubrication and lubricating oil quantity of oil in the tank.
In order for the saw chain and guide are automatic and reliable lubrication engineers recommend the use ofhigh-quality oil, less pollution of the saw chain and guide plate, such as strong resistance to aging andrapidly biodegradable lubricants. Low resistance to aging, lubricant easily resin, hard sediment will form it is difficult to get rid of, especially around the saw chain, clutch and on the saw chain. Serious when stuckin pump. In addition, do not use used oil. Waste lubricating oil does not have the required lubricationability and number of contacts used lubricating oil may cause skin cancer, used lubricating oil will damagethe environment.
To fill every time you fuel oil saw chain oil, must ensure that the fuel is exhausted, saw chain oil tankwith a little residual lubricant. If oil does not reduce the amount of oil in the tank, it may be caused dueto lubricant jam. To check the saw chain lubrication, clean oil, if necessary, to service dealer for help.
For newly manufactured equipment, during the break-in period to avoid unnecessary high loads of homework,therefore, in the first three boxes don't fast idle before fuel runs out. Due to the moving parts must berun-in period running, so in the meantime short cylinder with the friction resistance. Engine use up about 5to 15 after the tank has reached its maximum power. Chain saw during normal operation, do not adjust themixing ratio of oil is too low to significantly increase the power, which may damage the engine.
In addition, to always check the tension of the saw chain. And has been in use a long time compared with thesaw chain, the new saw chains need to tighten more often. In cooler conditions, saw chain guide plate sidemeshing by hand but is still able to pull along the guide plate and the tension is correct. When theoperating temperature is reached, expansion of saw chain, start to slack. Not allowed to bite the undersideof the drive chain out of the Groove, or saw chain will fall off. If necessary tighten again saw chain. Whencool, chain saw will shrink. At this time be set loose saw chain, otherwise it will damage the crankshaft andbearings.
Chain saw use not to be ignored in detail
In the chain saw, there are a few details of the operation requires special attention. First of all, when thechain saw is started, don't pull the starting rope to end. Starts gently pull start lever, until the stopposition, and then quickly push pull while pressing<, SPAN style="PADDING-BOTTO, M: 0px; MARGIN: 0px; PADDING-LEFT: 0px; PADDING-RIGHT: 0px; PADDING-TOP: 0px" id=noHighlight_0.3059304179623723> down before hand. Technician says, don't pull the Startercord completely to the floor, or you may break it. In daily use, users often do not pay attention to thisdetail, over time, start the rope easily spoiled. Also note, don't let the start lever free play, and shouldslowly back into the Cabinet, so that the Starter rope can nicely rolled up.
Secondly, the Max engine after running for a long time, you need to let it idle for some time, so thatcooling air flow, release most of the heat in the engine. This is to avoid installation in engine parts(ignition, carburetor) thermal overload occurs.
Again, if the decrease of engine power, may be caused by dirty air filters. Remove the carburetor box cover,remove the air filter, clear the smudges around the filter and the separation of the two parts of the filter,brushing with the Palm net filter or blow clean with compressed air from the inside out.
If the filter is dirt stuck, need to be placed on a dedicated filter cleaner or a clean, non-flammablecleaning solution (warm soapy water) wash and dry. Do not use a brush to clean the fur filters.
When you reinstall the air filter, remember to check the damper and torsion spring is properly seated.
Aftercare in time to complete
Chainsaw maintenance, high priority is the saw chain. Maintaining and sharpening saw chain correctly only asmall pressure can easily cut into the wood. When routine maintenance, pay attention to check the saw chainon the chain link for crack and fracture of rivets. Replace any damaged or worn parts on the saw chain, and then mix with original new parts of the same shape and size. Carbide saw chain is particularly resistant toabrasion.
Saw chain sharpening job, usually can be accomplished by a service dealer. You must keep the jagged angleswhen sharpening. All jagged angles must be the same, if they are different, the saws turn not smooth and wearuntil the saw chain breaks. All tooth length must also be the same. If different, the tooth looks different,this will also cause the saw chain rotation is not smooth and eventually break. Thoroughly clean the saw blade after sharpening the chain, poke or dust cleaning attachment in the file above and lubricating the sawchain. If the long time does not use, ensure the saw chain lubrication requirements under good conditions forstorage.
For storing the chain saw for a long time, and fuel tank in a well ventilated area be emptied and cleaned.Always run the engine before the carburetor dry to prevent carburetor diaphragms sticking together. Removethe saw chain and guide plate, clean it, then sprayed with oil. Thoroughly clean the machine, especially thecylinder cooling fins and air filter. If you use biological chain lubricants, lubricating oil tank to fill.
Need to be aware of is that even by the provision requires the use and maintenance of the chain saw, certainparts of the engine will also have normal wear and tear and loss, so must be used according to the type andcircumstances, to be replaced in a timely manner. These components include: the saw chain, daoban,transmission components (clutch, clutch drum, sprocket), spark plugs, filters, starter device and vibrationreduction system for spare parts. |
