Chainsaw - a useful tool for timber gardening and farming.Its effectiveness depends on the extent and severity of wear of the cutting elements.Sharpening the chain saws can be assigned to a specialist.However, having studied the necessary information on the matter and with a little practice, do the job on their own and be able to novice.
How to determine that the saw needs sharpening?
working surface of the chain saws make two types of units: cutting and limiting teeth.The former have a greater height than the latter.The difference in height usually is always on the same level - 0.5-0.8 mm.If it changes the efficiency of the blade is sharply reduced, it begins to lead the way.Time sawing increases.The need sharpening can also be seen in the form of the remaining chips.Sharp teeth create a uniform chips.Its particles have a square shape.If the units of ground off, the shape and size of the particles will be different.From under the chain starts to pour fine dust mixed with the chips that looks like needles.Working with such saws is not only inconvenient, but also dangerous.Its extension may cause damage to the mechanism of injury and the person.Therefore, in such cases it should be immediately organized sharpening chain saws.
What tools are needed?
professional loggers often use the machines.They established a special wheels for sharpening chain saws.Normal gardener can do without buying expensive equipment.Set for sharpening the saw chain includes the following tools:
- flat file,
- file cylindrical shape,
- composed pattern,
- gripe (this tool will facilitate the work, but without it is possible to do).
sharpening process
superimposed on the circuit pattern so that the direction of the arrow coincides with the vector of the chain.The angle of a file should be selected for each circuit individually, based on its pitch.Sharpening made easy precise movements in the direction of the tire.Each tooth requires the same number of approaches.Cutting teeth are processed in two.The first - on the one hand, the second - on the other.Sharpening the chain saws on a template eliminates errors and helps to avoid vibration saws in the future.For teeth-limiters used flat file.The pattern suggests two positions for a variety of tree species: «H» (hard) - for solid, «S» (soft) - soft.
Operation saws
If you observe basic rules of use, the sharpening chain saws will require much less, and the device will last much longer.You should never forget the lubrication mechanism.The oil must flow continuously to the surface of the sprocket, chain and guide bar.During operation, you must ensure that the chain is stretched.Lack of tension threatens slipping and may pose a serious health hazard.You can not use a blunt chain.Its application will lead to excessive load on the gear and saw a rapid deterioration of parts.
