Chain saw — modern designs, marking features, nuances of replacement and sharpening (75 photos)

Almost any owner of a residential private house or a private plot has a tool for cutting wood: a jigsaw, a saw, or a powerful electric saw that works with fuel. Undoubtedly, any of the listed equipment will require a certain skill and skill in work. If you own an electric tool, you need an elementary knowledge of the characteristics of the circuits, how to replace them and competent sharpening.

The electric saw is an ideal ergonomic tool for regular home repair work: fence construction, barn repair, log sawing. Due to the compactness of the design, it is convenient to use it both indoors and on the site itself, which only requires an electric power source.

Unlike gasoline options, there is no need to spend money on fuel, and the accuracy of the work will be at the highest level.

The only drawback is the required interval of sawing wood, that is, the saw is in working condition for forty seconds, and then rests for twenty seconds.

Summary of the article:

The photo of the chain saw shows an old worn model that was actively used. Such a part must either be sharpened or completely replaced with a new one, since in importance it stands in one place with the engine.

Before choosing a chain for a saw, it is recommended to take into account the following nuances:

the type of chain directly depends on the purpose of its use. So, when demanding the highest power of the tool, it is better to take the option with a step of 3/8 inches, and lower loads allow 0.325 inches. In this case, you can not take into account the volume of the cylinder;
when replacing any spare part, it is better to take products from the same manufacturer to avoid incompatibility in general;
look at the angle of sharpening, which affects the care, replacement and future work process. With large volumes of work, it is reasonable to take an angle of 30 degrees. But more complex wood processing will require sharpening the chain with an index of 10 degrees;
the size of the product must correspond to the size of the tires. But, despite the correct selection of length, it can stretch during use, which is eliminated by removing several links.

Of course, experts recommend taking into account the quality of the material and the way it is processed.

Teeth and their dimensions

An important element of a modern chain is the teeth, which have distinctive features, which must also be taken into account when buying. Any detail of the tooth bears an individual name.

The slope of the blade from the end and the sliding surface connect the front angle, which has a maximum of 85 degrees. It should be adjusted when working on sharpening the chain. Moreover, absolutely every detail, its parameters are directly responsible for the cutting actions of the electric saw.

You will not be able to adjust the angle of inclination yourself, special standard norms have been created for these purposes, which should be strictly observed.

The rear angle, the most important, has dimensions from 50 to 60 degrees.

Replacing the chain at home

Any manufacturer allows the replacement of the chain with their own hands, in addition, they also attach precise instructions for self-replacement or repair of equipment.

The first step, that is, before pulling the chain on the saw, will be the purchase of a new part.

Perhaps the most popular and relatively cheap option is a side tension saw. To replace the chain , you need to perform several actions:

Move the protection shield away, while lowering the brake at the same time.
Turn the control tension screw using a screwdriver, then unscrew the nut, loosening the tension.
Remove the lid.
Separate the tire and the sprocket.
Remove the used chain by replacing it with a new one.
Then return all the parts to their places in the exact order.

Note that it is necessary to tighten the chain with smooth movements, that is, not to make rough jerks. After closing the plastic cover, you can fully tighten the chain with a screw and nut. More branded designs suggest the presence of wing nuts for quick tension, which provokes a faster replacement.

Sharpening the electric saw chain

Undoubtedly, the quality of the equipment is significantly reduced over time, since wood is not the softest raw material, and the cutting surface tends to gradually decrease in efficiency. During the untreated teeth will lose their initial shape altogether and they will have to be completely replaced, which will require the greatest financial costs.

It is worth considering that the condition of the teeth requires constant monitoring, since there is no specific time of damage to parts. A blunt part can be easily identified by the quality and size of the chips.

The blunt teeth of the saw release very fine and dark dust from the wood. Therefore, it is necessary to immediately inspect the condition of the working tool. Sharp elements suggest the absence of chipping, violation of integrity and changes in the type of cutting edge.

Of course, you can turn to a professional master for sharpening saws, who will perform the work without a doubt more efficiently. But, a more budget option would be self-processing with special tools.

Most craftsmen use files for these purposes, but this requires a special set:

the file is flat, correcting the depth restriction;
the frame defining the angle;
round detail with reference strips;
caliber.

As a rule, the chain is inserted into a tire fixed in a vise, an appropriate file is selected that fits the diameter of the teeth. It is necessary to notice the first tooth in order to avoid a repeated sharpening circle.

The master makes precise rhythmic movements in one of the sides. The gauge is applied to the edge with the end face to the restrictive part. At the end, it is necessary to check the quality of the tool by making a control incision.

To prolong the life of the tool, it should not be used on materials other than wooden surfaces! To do this, you should monitor the absence of third-party metal objects in the wood (nail, bolt, staples). It is recommended to regularly lubricate the chain and check the device for overheating.

It is better to use high supports when working with the tool, in order to avoid tire contact with the soil. It is necessary to accurately observe the intervals of the operating mode of the equipment. Observing these simple rules, you can significantly extend the service life of the electric "assistant"!
