How To Remove The Chain From The Saw

How to choose a good saw: what to look at before buying a machine?
The advantages of an electric saw. Types of equipment for working with wood. What to look for when choosing a chain saw: instruction. Helpful advice from the pros.

Types of electric saws

If you need to cut a variety of materials – plywood, wood, plastic, chipboard, metal pipes and sheets – you should purchase a circular saw. Cutting is done with a rotating saw blade, and there are specific types of blades for each material. There are two variants of models – manual and fixed, attached to the bed.

A fairly versatile tool is a reciprocating saw, which is often used for cutting in hard-to-reach places. It is convenient for roofing and installation work. The working element is a file, the length of which varies from 0.1 m to 0.35 m. It produces oscillatory or translational movements.

Smooth, neat, even curly cut can be made with a jigsaw. It works equally well with ceramics, wood, laminate and metal. The file (working blade) of a jigsaw is indispensable if you need to cut a round hole or make a curved cut.

The best saws for giving are recognized as chain aggregates, the main active element of which is a tire with a chain stretched over it. It is easy to use, relatively compact, and does not require fuel mixture preparation. Almost all gardening work can be done with its help: to knock down an old tree, cut off branches and branches, saw a trunk. It is good for carpentry and construction, especially in confined spaces.

When working with a chain saw outdoors, you must follow the safety rules. For example, you cannot use the tool when it rains – a short circuit is possible

Electric tool advantages

Both an electric saw and its gasoline counterpart are good for garden and summer cottage work, but many still choose the first option. Why is he so attractive?

The power tool, indeed, has a whole list of advantages:

  • Does not require constant material costs for fuel – gasoline;
  • Easy to use and maintain;
  • Makes less noise during operation than a chainsaw;
  • Clean from an environmental point of view – works without exhaust gases;
  • Allows for cutting indoors;
  • It works equally well, despite the climatic features (the gasoline analogue has problems with starting in frosty weather).

If the power source becomes unattainable, a rechargeable chain saw will come in handy, for example – Makita BUC122Z (price – 9000-10000 rubles). Battery and charger must be purchased separately

Engine power

This is one of the most important indicators. For gardening work, a tool with a power of 1000 W to 2100 W is suitable, but it is better to purchase a stronger unit. The fact is that powerful saws respond more adequately to voltage drops in the mains, therefore, they will last longer. For example, the engine of the popular CHAMPION 420 model has a power of 2000 W, that is, with small voltage fluctuations (200-224 V), it will remain operational and will not allow critical overheating. In addition, an indicator from 2000 W is a guarantee that in an extreme situation, when a large amount of work is required, the engine will withstand the load.

How to choose a good saw: what to look at before buying a machine?

how to remove the chain from the saw

Rest in the country can hardly be called passive – either a gazebo must be built, then a bench must be made, then old trees must be removed from the garden by sawing them into neat blanks to create a decor. In addition to the usual hand tools for woodwork – a plane, chisel, hammer, jigsaw – many owners have more serious equipment, such as a wood saw. With its help, not only the porch – the whole house can be built.

Chain selection

The saw chain is as important as the motor. And its choice should be approached as responsibly as possible, this will help to avoid many problems during the subsequent operation of the tool. You need to choose a chain for a saw, focusing on the following parameters:

  • Saw model compatible. Despite the large number of alternatives, it is best to purchase a part from the same company that made the tool itself.
  • Purpose of use. If the saw will be intended for household work at home or in the garden, then it is optimal to select a part with a chain link pitch of 0.325 ”. Large jobs require a high performance 3/8 ”pitch chain.
  • It should be the same length as the tire. Stretching or sagging of the part during long-term operation is eliminated by removing part of the links.
  • For large volumes of work, it is recommended to use high-performance saw blades with a sharpening angle of 30 °. For complex processing, for example, wet or frozen wood, sharpening of teeth at 10 ° is used.

It is also important to take into account the material with which you plan to work, and the method of cutting it. So chains with a smaller sharpening angle are suitable for ripping. In this case, their productivity will not be so high, but the operational life will significantly increase.

The choice of the saw bar must also be very careful. First of all, it is worth paying attention to the material: the stronger it is, the longer the part will last without failing. The following parameters are equally important:

  • Length (the distance between the stop and the toe) – the greater this indicator, the larger the tree will be cut. Lengths of 12-20 "are advantageously used.
  • Groove width – for household saws, parts with grooves up to 1.3 mm are used; 1.5-1.6 mm on a more powerful tool.
  • Shank – determines if the tire is suitable for a particular electric stove model. It is better to purchase a branded part, although shanks from different manufacturers are often interchangeable.

Only with the correct selection of sawing elements will the further operation of the saw be effective, safe, and does not require additional money or time investments.

How to put the chain on the saw correctly

When performing an impressive amount of joinery and carpentry work, a reliable saw is needed, regardless of whether the wood is being cut in the house or outdoors. The quality and serviceability of the tool directly depends on the condition of its main elements: chains and tires. Correctly placing the chain on the saw is the main task facing the user, which greatly facilitates subsequent operation. Practical recommendations will help perform this action even for those who have never done this before.

How to properly adjust the chain tension

The tension level of the saw chain directly affects the safety of the tool, work efficiency, and service life. It is very easy to check the tension level: closer to the center of the bar, grab the saw blade by pulling it up. At normal tension, 1/3 of the point should remain inside the seat, and the chain can be safely rotated by hand.

Various saw models have wing nut or screw chain tensioners:

  • Adjustment on tools equipped with a quick tension system is carried out by rotating a special wheel located under the sprocket guard. Clockwise rotation tightens the saw element, counter-clockwise loosens. With this mechanism, the tension can be changed during operation.
  • Tension adjustments for screw saws are a little more complicated. You will need to loosen the tension screw and side nuts, then you can turn the screw. With increasing tension, the chain must be turned forward to check the smoothness of the movement, to eliminate the backlash of the hinges.

How to put the chain on the saw correctly?

It is worth noting that tool manufacturers do not prohibit self-service of the tool, and provide instructions on how to remove and install the chain on the saw. If we consider one of the most common types, where the chain tension on the saw is lateral, then the algorithm looks like this:

  • We move the shield, while simultaneously releasing the brake.
  • Using a screwdriver, we turn the control tension screw.
  • We screw on the nut, thereby relieving the tension.
  • Let’s dismantle the cover.
  • You will need to separate the bar and chain from the sprocket.
  • You will need to remove the old chain from the bar and install a new one in its place.
  • Now all previous manipulations are performed in reverse order.
  • The chain must be tightened with smooth movements, without jerking.
  • After the plastic cover is closed, the final tension of the saw chain can be made using the nut and screw.

Power tool manufacturers are relentlessly modernizing their devices, thanks to which new devices appear that greatly facilitate all processes related to the operation and maintenance of units. Today there are various chain tensioners on the saw, often using wing nuts for surgical intervention.

Chain sharpening equipment

There are also more effective ways to sharpen the saw chain; manual and electric machines are used for this. Power plants require access to an energy source, but at the same time have many advantages, including:

  • Ability to work with various saw chains.
  • You can adjust the cutting depth and pitch.
  • The creation of the limiter is as accurate as possible.
  • You can set the required cutting angle.

How to choose the right saw chain?

When faced with replacement saw components, users wonder which saw chain is the best. Focus on the purpose for which you use the tool, as well as the compatibility of components for other brands:

  • If power is important to you, choose a chain to the saw, with a large pitch. In the event that the loads are relatively low, a smaller saw chain pitch is sufficient, while the cylinder volume is not important.
  • Consider what angle of sharpening the saw chain is used, this indicator is important for subsequent maintenance, repair work or replacement. The thirty-degree angle will provide maximum performance as it can handle heavy loads better. When working with damp or frozen material, an angle of ten degrees is appropriate.
  • The length of the chain should be the same as the bar, do not worry if it stretches or sags during use, as this can be easily fixed by removing a couple of links.

In order to select the saw chain as accurately as possible, in addition to the technical characteristics of the equipment, it is worth considering the way in which you cut, as well as the materials to be processed. If a longitudinal cut is required, a saw chain with a minimum sharpening angle is recommended, in which case the performance may be lower, but the service life will significantly increase.
