How to Tension a Spring on a Trimmer

Do-it-yourself starter repair for gas drills, lawn mowers, trimmers

But now we will examine the more widespread case when the breakdown is not so serious and show how to repair the starter with your own hands, if the cord breaks without any destructive consequences or does not unwind due to the fact that the spring inside has simply fallen off and is out of gear. At the very least, at first the desire is to believe in it. But in order to find out whether it is so or not, it will be necessary to disassemble the starter.

How to Tighten a Spring

How to repair a gasoline engine starter with your own hands?

In the case of a break in the starter cord, everything is clear: we take out the old rope, take a suitable length and thickness (linen possible), thread it through the hole in the coil, tie a knot. Next, we cock the spring to the speed we need, only then we fix the handle. and voila! details on how all this is done are shown below.

But what if we have everything in order with the rope, and the starter coil (pulley) does not reel? Consider this issue step by step on the example of the ADA GroundDrill gasoline motor drill starter, which has a pulley with two metal antennae for 2 hooks.

In the case of other types of manual starters of a similar design, which are widely used in gasoline lawn mowers, trimmers and motor drills, the entire repair process of the starter will look similar, differing only in some nuances.

Starter Repair: Disassembly

Unscrew the screw that secures the pulley to the starter cover. We take out the antennae, spring. The pulley itself is pulled out carefully so that the spring does not bounce into the face. Even with the most accurate disassembly, it usually flies out of the coil immediately and spins abruptly into a long metal strip or twists into rings.

If the spring bursts or one of its hooks and hooks breaks, then it is not possible to repair the starter simply and quickly. replacement of the spring is required. In order not to spend money on the purchase of a new starter, you can only search for it on sale.

In case the starter spring just broke, that is, one of the hooks is out of engagement, it is enough to insert it, if necessary, slightly tightening the hooks more tightly (just do not break it!) Install the spring with an external hook in the groove of the pulley and start twisting it while holding it fingers inside the coil and not letting it pop out.

Fill starter spring

Pressing the spring to the pulley, in a circular motion we wind the spring inward

The first time you insert the starter spring may not seem so simple, but everything comes with experience. With a little training, you can easily wind the spring into the pulley in a maximum of a minute.

Winding the starter spring is done. It remains only to assemble the starter and cock the spring to the desired value

How to assemble a starter?

The most important thing in the process of self-repair of the starter is to assemble it correctly.

After the spring is fully wound, you need to carefully turn the coil and insert it into the starter housing so that the second spring hook enters the groove of the housing.

When installing the pulley (black in this photo), we look through the hole in it so that the spring hook falls into the groove on the starter cover

Then, if there is a spring under the screw, we first install it, without forgetting to put washers on the bottom and top of the spring.

Carefully insert the cup with the antennae into the grooves of the coil and tighten the screw.

Then watch that the washer located on a spring did not drop out. Why is it important? The fact is that the spring scratches the plastic cup with its end, as a result of which the latter wears out and begins to more tightly press the screw against the coil. insert and re-tension the spring itself. spring on how you cock the spring. For this reason, a situation may arise that is very similar to a spring break: the handle is pulled out of the starter but not returned. However, when loosening the starter screw, this problem disappears. To fix such a malfunction of the starter is simple: just pick up a spring of the same diameter, but a little longer, or put an additional washer. If we just tighten the screw slightly, it will twist and fly out, and this will increase the likelihood of spring breakage, since the pulley will not fit snugly against the starter housing.

They screwed the coil to the body, now we need to tighten the spring. Before this, it is necessary to remove the starter handle from the rope in advance. If the knot is too strong, then you can simply cut it off or try to untie it, for example, using a pair of pliers. This is done so that after you cock the spring, you can thread the rope into the hole in the starter cover. The second end of the rope must be fixed in the coil before it is installed in the body, it is not necessary to wind the rope onto the pulley before pulling the spring. do it after.

Before you cock the spring, estimate how many revolutions of the coil the rope should be wound. Suppose the length of the rope at the starter of the Ada GroundDrill-5 motor-drill is 5.5 turns around the coil. In this case, make at least 6 revolutions of the coil in the direction opposite to the direction of winding.

So let’s get started. Without reeling, insert the rope into the groove in the reel specially designed for it. Everything is ready, proceed to pulling the spring. To do this, rotate the coil counterclockwise. in the opposite direction to the direction of rotation of the coil when winding the rope. It is more convenient to do this not on the knee, but by pressing the starter with one hand to the floor, and with the other turning the coil directly behind the rope attached to it. How to repair a starter on a trimmer do it yourself. How to disassemble and assemble the starter, wind the spring and replace the cord. If the experience is not enough, then the pulley itself can be rotated directly with two hands, but the rope will interfere with this, which can create additional inconvenience. After the necessary number of revolutions is done, we pass the end of the rope through the hole in the starter cover, put on the handle, fix it with a knot. It is more convenient to do this together with a partner, so that accidentally the end of the cable does not wound inside the starter.

By the way, on our own you can make some refinement in the design of the starter in order to more securely fix the end of the spring inside the coil. Then anyone has enough imagination. Now I will explain why this is necessary. It often happens that the spring in starters of this type after the first such independent repair and installation of the starter on the unit flies again after a few jerks. the hook does not hold in the recess of the coil. And this is despite the fact that the coil is almost tightly attached to the starter cover and the spring there should not be free to hang up and down, and even more so until the spring comes out of engagement. It turns out that when the cable is pulled, the spring pulls out, pulls out of the groove. In this case, you can do the following: cut a narrow strip of metal, which in thickness could be squeezed into the groove of the coil along with the spring hook itself. So the hook will not freely hang in the groove, which means it will not be so easy to break out.

A metal plate tightly inserted into the gap between the spring hook and the groove walls will hold the spring securely

Another way to solve the problem is to drill small holes in the coil on both sides of the groove and, having inserted the spring hook, fix it with a thin wire threaded through these holes. But here you need to manage to make sure that this wire does not touch during rotation of the starter cover from the inside and thus does not slow down the pulley. Alternatively, tighten the screw loosely or replace it with a similar slightly larger length. You can consider the option of installing some kind of gasket between the cover and the coil.

Is the design of the starter for your gas tool different from the above? Faced with another malfunction or do you know the best way to repair a starter with your own hands? Ask questions, share your experience with others. together we can solve the problem of frequent starter breakdowns once and for all!

How to Tension a Spring on a Chainsaw

High-quality DIY chainsaw starter repair

A chainsaw is the main tool with which you can stock up firewood for a bathhouse or fireplace, you can also use it when working on a summer cottage or in a personal home. Subject to all operation criteria and the implementation of preventive measures that are provided by the manufacturer, the chainsaw can last a long time. But after the lapse of time, small malfunctions may appear, which can be controlled without the help of others. For example, repairing the starter of a chainsaw with one’s own hands is completely capable of observing the sequence of operations.

Chainsaw starter device: 1. starter screw, 2. bushing, 3. easy-start spring, 4. screw, 5, 6. starter coil, 7. baffle, 8. starter cover, 9. handle and cord, 10. screw.

Typical malfunctions

The following are more common tool failures:

  • obstacles in the ignition system;
  • stopping the chainsaw in the process of cutting;
  • loss of power during operation;
  • wear of some structural parts of the chainsaw (brake band, drive sprockets, anti-vibration parts);
  • tasks in the fuel supply system;
  • malfunctions associated with the starter.

In addition, you need to create a visual inspection of the chainsaw before work and preventive measures. These include chain lubrication, control of the amount of fuel consistency, and also the presence of the required amount of oil.

The spark plug is turned out to check its condition.

Any of the defects is eliminated by its own technology. How to tighten the roller shutter spring? Tell me how to tighten the spring on the handle should mention the chainsaw “taiga 214. Adjusting the carburetor on the Husqvarna chainsaw after we set up. So, for example, repair of the fuel system of a chainsaw should begin with an inspection of the corresponding filter. Then inspect the correct carburetor regulation, which is carried out using screws. Clearances should be set in serious agreement with the manufacturer’s annotation, which should be included with the chainsaw. The repair of the ignition system includes inspections of candles. If a strong deposit is detected, a change in the gap or other visible damage, this element must be replaced.

Starter repair work

Obstacles to the operation of the starter may not allow the tool to start. In other words, after the cord is pulled, the chainsaw does not start to work.

The causes of the malfunction are:

  • broken or cracked pulley;
  • bursting spring;
  • rush trigger cable.

Before repairing the starter, it is necessary to prepare the tools with which to perform work:

  • a set of screwdrivers or a special tool that is supplied with the tool by the manufacturer;
  • rope, which will be used as a replacement for a torn cord if necessary.

A large amount of black soot on the spark plug indicates a malfunction in the engine.

Before proceeding directly with the repair of the starter and finding out the causes of malfunctions, it is necessary to remove it from the tool body. To do this, unscrew several screws that hold the side cover to which the starter is attached. This is done with a screwdriver or a specialized tool.

After the cover is unscrewed, it is turned over and inspected. Next, unscrew the screw with which the starter is fixed. How to pull a chain on a chainsaw. After that, the clamp and spring are dismantled for a smooth start. Now the pulley on which the cord is wound is available for removal. After the knot on the rope is untied, it can be pulled out from the pulley and replaced with a new one. Provided that the starter’s loss of functionality is connected with a break, this may be sufficient to eliminate the breakdown. However, the remaining parts that make up this element of the chainsaw should be carefully inspected.

When examining the components of the starter, the following malfunctions can be identified:

Most often, damage to the soft-start spring occurs from the end where it is visible when the housing is disassembled.

  1. The pulley may be damaged. Cracks or tears are possible, as well as damage to the rear. How to pull the chain? To properly tighten the chain on the Husqvarna chainsaw with the engine idle, the screws are first released. As a result of these problems, the tool cannot do the work.
  2. Damage to the soft start spring. In this case, the spring itself may be mechanically faulty, and there may be defects in the place of its attachment. The weakest point of this element is precisely the mounting location and the tip of the spring, which is inserted into it.

If defective or partially damaged starter parts are found, they must be replaced with new ones. At the same time, new elements must correspond to the model of the saw being repaired.

After the repair is completed, the starter must be assembled correctly.

The pulley is mounted on top of the spring. At the same time, it is necessary to check how much they are interlinked. Installing the chain on a chainsaw, how to properly tighten and check the tension if you have a chainsaw at home, then you should know that it needs special care. To continue the repair, the pulley must be wrapped. This must be done so that during rotation, he pulls the cord into the starter. After it is untied, it is first required to replace the smooth spring. Chainsaws and how in a chainsaw video, how to do how to pull a chain on if u. It is enough to make 3-4 turns to give the required voltage. Previously, the rope is passed through the hole in the lid of the chainsaw.

Practical recommendations

In order to match the holes for fixing the cord in the pulley and housing, you may need to make a few more turns. A new rope is threaded into the technological hole and a loop or knot is made: this will allow it to slip out of the pulley. The rope is set aside so that it does not interfere with further work. Next, fix the pulley.

First you need to replace the soft start spring. It can be used the same if no damage is found in it. or new if replacement is necessary. On top of the spring set the starter clamp, which is fixed with a special screw. In the article we will tell you how to adjust how to adjust the carburetor on the video chainsaw. It reliably fixes the clamp for a long time, preventing it from skewing and swaying. I have dangling carburetor studs on a chainsaw blade; how can I change it? After this, you need to make several turns of the rope and run it inward. The cover with the assembled starter is installed in place. Using screws, it is secured.

After the repair and assembly, you can begin to work. Self-repair of the starter does not take much time and does not require complex skills, but it saves time and money if you perform such work in the service center.

Chainsaw repair should be approached responsibly and promptly to carry out preventive examinations, monitor the quality of the fuel and oil used. These simple manipulations will increase the duration of the tool in working condition.

How to Tighten a Chainsaw Starter Spring

Starter for chainsaw. Learning to repair yourself

To quickly start any chainsaw, a starter is required. With accelerated scrolling of the crankshaft of the tool, the fuel-air mixture supplied to the engine is compressed, not its subsequent ignition. How to replace a spring. Details of replacing the chainsaw starter dogs, how to tighten. Therefore, the normal operation of the starter for a chainsaw determines the operability of the entire mechanism.

Chainsaw starter device

The principle of operation of the starter for a chainsaw is as follows. A handle is installed in the groove of the body through which a cable is passed. The principle of operation of the starter for a chainsaw is how to put a spring on the starter. If the handle is sharply raised, the cable is pulled out and engages the drum of the ratchet mechanism which transmits movement to the drum with splines provided on the shaft. With all this, the crankshaft makes several revolutions, and the working mixture in the space between the piston is not compressed by the cylinder head. Accordingly, when lowering the handle, the contact between the ratchet is not lost by the splines, the shaft does not stop.

With an increase in engine volume, an unnecessary amount of the fuel-air mixture, necessary for its subsequent ignition, increases, so the number of jerks for the starter cable for saws with high power increases. Therefore, with the intention of accelerating the return of the drum, involuntary return springs made of steels with high elastic properties are used.

Facilitation of starting a chainsaw is implemented in the following ways:

  1. By preliminary enrichment of the working mixture, for what purpose there is a special damper in the design of the carburetor.
  2. By installing an automatic decompression valve, which reduces the working pressure in the cylinder of the chainsaw.
  3. The installation of an additional spring, which during the movement of the cable facilitates the unwinding of the crankshaft.
  4. The presence of some chainsaws (nettle, Partner S series, Maxcut, etc.) in the design of a primer is a pump that provides preliminary pumping of fuel.

Chainsaw starter repair

With frequent starts of the chainsaw, some parts of the starter are constantly subjected to dynamic loads. As a result, the cable may burst, several teeth of the ratchet may crumble, and the shaft will turn at a much lower speed. Therefore, the audit and even repair of the starter are operations that are sometimes carried out several times during the season.

Cord replacement

When it is pulled, the cable is constantly rubbed against the starter housing. For replacement, the assembly of the assembly is disassembled and the ratchet drum is carefully lifted so as to prevent the return spring from jumping off its sockets. It is better to do this work together: the assistant fixes the spring, while the cable is being replaced. How to pull a kick starter spring on a scooter repairing a chainsaw starter. After fixing the cable in the handle and in the grooves of the drum, the cable is wound on the roller, and the body is assembled.

Spring repair

If the starter spring material is poor, the spring bursts (usually at the point of attachment to the drum, where it forms a loop). Replace the spring in this case is not worth it. It is enough to thoroughly clean its surface from dirt and traces of lubrication, carefully grind the place of destruction, and then release the spring at 600. 650 ° C (the spring steel should acquire a crimson color). It is necessary to cool the spring slowly, but at 100. 150 ° C it is already possible to gently wrap its end in the form of a limiting protrusion on the inner surface of the drum (the steel will acquire the necessary ductility) and put it back. A simple repair of a chainsaw starter repair starter chainsaw how to properly pull a flail over. The elastic properties of the spring will not change.

How to put a spring on a chainsaw starter?

Putting the starter spring in the desired groove is not easy, even for an experienced user. First, the spring should be twisted to the previous diameter and installed in the cavity of the drum hub. The outer end of the spring is fixed by the limiting protrusion, and the outer one should be positioned opposite the hole in the lock with a screwdriver. The loop at the inner end of the spring with a screwdriver is combined with the hole, after which the disc is lowered. By rotating the disk, it is checked whether the ratchet mechanism dog is in place. Next, the ratchet itself is assembled.

After installing the spring, you must adjust its tension. How to wind the starter spring, tension the spring. Starter handle like. To do this, a cable is inserted into the groove on the circumference, and a return spring is twisted around it. After removing the slack, it is better to wind the spring an additional few turns to ensure the required tightness of the part.

How to tighten the roller shutter spring?

Strictly speaking, several springs are included in the design of the roller shutter. The first spring is part of the element that secures the canvas to the shaft. It does not need to be set up, since it provides only the smooth running of the web and the amortization of the inertia of its movement. The second spring is the main element of the so-called PIM (spring-inertial mechanism of roller shutters), which provides a quick and uniform lifting of the canvas.

The essence of adjusting the PIM spring is to adjust the number of revolutions it makes by lifting the web. As a result, the lifting speed is adjusted and the length of the web is adjusted. that is, the number of lamellas that are needed to completely block the opening.

The greater the number of revolutions, the spring is twisted. the greater the strength of its unwinding. and the greater the speed of lifting the canvas. However, it is not worth striving to ensure that the lamellas literally take off (or rather, fly in) into the box. the limiters that stand on the bottom lamella may not be able to withstand.

PIM spring tension

The spring is pulled when the web is worn on the drum. PFM tension and adjustment are performed according to the following algorithm:

  • traction springs are put on the canvas (included);
  • the spring mechanism is pulled (the number of revolutions depends on the diameter of the shaft and the overall dimensions of the web. you can find out the approximate number of revolutions from a special table);
  • the spring is fixed with special brackets;
  • traction springs are filled into the shaft into special slots located at its ends;
  • spring stopper is removed;
  • the smoothness and speed of the blade is checked (it is imperative to hold it with your hand in order to exclude sharp impacts of the stoppers on the bottom lamella against the edge of the box and, if the stoppers are not already installed, avoid completely wrapping the canvas on the shaft).

Speed ​​adjustment

We have already indicated that the number of turns of a PIM spring depends on such parameters of roller shutters as the diameter of the shaft and the weight of the web, as well as its length in the unfolded state. At primary winding, no special accuracy is required. all you have to do is get into the interval indicated for the spring of your chosen model and the diameter of the shaft that stands in your roller shutter. However, in the future, with more precise adjustment, it is worth acting especially carefully.

To reduce or increase the number of revolutions, it is necessary to remove the blade from the shaft, removing the traction springs from the perforation on it. Before putting on the canvas, the spring, as in the first case, is fixed with a locking bracket.
