Test Drive Makita electric saws UC3520A replacement chains flipping of an incorrectly installed tire, and again the test.
Saw chain lubrication system.
You can extend the service life of the sawing element as follows:
Before starting work, you need to make sure that there are no solid metal elements in the workpiece. If the element for cutting comes into contact with the metal workpiece, then notches or chips will appear on the chain, which cannot be removed in the future.
Do not sharpen on the ground, as digging into the ground can clog the oil grooves. As a result, the chain will not be lubricated and will wear out quickly.
Be sure to keep an eye on the saw blade. Jamming should not be allowed, as as a result, the metal will overheat and reduce its service life.
It should be determined whether it is necessary to sharpen the saw. To do this, you need to pay attention to the chips: if they are small or have a dark color, then the chain is dull. Blunt edges are not able to remove the desired cutting layer; as a result, the chips are crushed. The quality of the sharpening of the tool can also be determined by inspection. These circumstances lead to the problem of how to choose a chain, taking into account the length. The part that is used for sawing must be free of defects in the form of torn pieces. The shape of the serration and cutting edge must be the same as when not in use.
If these factors do not meet the relevant requirements, then the saw must be sharpened.
If you perform work using a blunt file, this can affect productivity, as well as the period of possible use of the tool.
In the case of using blunt elements, the load on the electric motor will increase, as a result, it will overheat and all its parts will wear out before the specified period.
You can sharpen an electric saw as follows:
In this case, you need to do the following:
The first step is to remove the chain from the shank.
The chain is installed on the guide element of the device and tightened with a roller and a ratchet. Power saws can be like a cross to remove the cover on the power saw chain. These elements will hold the chain by the cutting teeth.
You can set the sharpening angle with a protractor, which is installed on the device.
The abrasive wheel must be lowered, with its help a small part of the metal is removed - approximately 0.001 m. Thus, the chain is straightened and sharpened.
After straightening the first tooth, the guide element will need to be rearranged to the next one. Not sure how to rivet a chain on a motorcycle? We will tell you about 4 methods of varying degrees of difficulty and detailed instructions with video comments. Thus, all the teeth are straightened.
With the help of such a sharpening, it will be possible to withstand the rigid framework of the fixture editing.
If you plan to buy such a device for personal use, then it is recommended to purchase not an electrical device, but a manual one. In fact, we can remove it (after we removed the chain from and the load on the variator from. The latter is much cheaper.
It is quite simple to repair and sharpen an electric saw with your own hands, you just need to prepare all the necessary tools and follow the correct sequence of actions.
Grinding and sparks, because of what may be
Tell me please. Chain vibration appears on the Makita UC4051A electric saw if the tire is more than half inserted into the log. What could be the reason?
Damn, I noticed that my saw also has a slightly sparking rotor, especially at the start. Probably burnt. But plowing for now !?
How much does such a rotor cost for Makita 4020. Thanks to you, now the whole tool is being repaired.
the same saw. do not tell me what could be? under a BIG load, it bursts in the area of the gearbox. I cannot understand where and what is bursting. During normal operation, everything is in order.
I have the same 2008 as new ☺
A question for a professional. What kind of lubricant was put into this saw and what kind of lubricant to use for the screwdriver. Thanks in advance.
There was a desire after viewing to sort out my saw and completely clean and check the anchor.
Like and subscription. housings 3010 fit 3520. Thanks a lot
Many thanks! I liked it very much. It seems to me that with a transverse motor the saws are more reliable than with a longitudinal one.
Alexander, tell me, on electric saws, the chain is lubricated like on a chainsaw, that is, there are holes in the tire in the groove where the chain runs
Sorry for the question in advance. Maybe you already have a video about such a Chinese electric saw - the FORTE FES 24-40 electric saw (Straight). But I didn’t find it. You could not make a video about disassembling and assembling an electric saw, as well as the advantages and disadvantages. It is from you that the video is clear and very interesting to watch.
Good afternoon. Please advise the model of an electric chain saw for a summer residence with metal gears, otherwise I just can't make a choice? I was inclined to alko eki2200 / 40 alko eks 2400/40, but it turns out there are plastic gears, and there is no trust in them.
Alexander, not in order, why haven't you changed the chain sprocket? it can be seen that it is worn out (the chain has grooved tangible grooves on it). I don't know for sure, but they say because of such an asterisk the canvas is quickly killed and the chain itself becomes blunt faster.
Of course, I am an altruist, but for my money to change what I was told not to change is somehow not a hunt))
Thanks for your review! I have a question whether the gears are really metal? And have you encountered Al-ko Electric Saws? If you have encountered it, tell us + -. Thank you:)
please tell me and which saws have a metal gear wheel. and which saws are better.
fucking! no offense but it's an ANCHOR!
Well this is class! What's one cleaning worth, or was assembling a new saw?
I want to ask about the tsn zzl 210 screwdriver is it worth buying, for reference I work on windows
Tell me in what chain saws metal gears ??
and did not try to grind lamellas? the wear does not seem to be strong, why change the rotor here are the brushes and at the last gasp
2nd lamellas are raised, is there any point in grinding?
Hello
Good afternoon. On little Lepse when planning a review?
In general, is it advisable to repair with such a breakdown? After all, the cost of repairs is comparable to a new tool.
Eugene Loftmi, well, the anchor costs 35 dollars, and the new saw is 130-140 dollars, so I think it is quite expedient.
Why grease the gears so much? Doesn't it spatter inside?
Alexander, good evening! ... please tell me the hitachi 24 perforator, changed the barrel, the gear which is in the fork (overrunning clutch), but it still cracks, I keep the cartridge cracking with my hands. ..the hit works flawlessly. what could be the reason?, maybe in the response gear that is in the head of the body? but it looks like it is not worked out (the gear that is paired with the bearing) thanks for earlier.

Like any tool, Makita power saws need preventive maintenance. From time to time it is necessary to replace those parts that are very worn out. This applies to any product in the line, be it the Makita UC3520A with a 1800W motor or the UC4530A with 2000W. If you do not pay attention to some points when inspecting and preparing the saw for work, the device may even break down.
Preparation is carried out in several stages:
Since the device is quite massive, for example, the UC4530A weighs 4.3 kg, we put it on the table and use a special key (supplied in the kit) to screw the fastening nut. Then remove the sprocket boot.
The bolt, with the help of which the chain is adjusted, is scrolled in the direction opposite to the movement of the hand on the clock. The pin should enter the left end position.
We pass the chain between the teeth of the gear, wrap the sprocket with it. On the top of the tire, the teeth should be in the direction of the arrow.
We put the tire back. The pin must fit exactly into the bus hole.
We fasten the sprocket cover back, manually tighten the fastening nut slightly.
Check that the saw chain is properly tensioned. To do this, lift the end of the bar, then turn the chain screw to adjust, this time in a clockwise direction. Be careful, the chain should be firmly pressed against the bottom of the bar.
It remains to thoroughly lubricate the bar and saw chain. To do this, you need to use a special chain oil that has an adhesive additive, biodegradable. The additive prevents liquid from being thrown away. The oil must be filled up to the lower level of the filler neck. Make sure that no dirt gets into the oil tank. To do this, clean the filler neck before filling.
Screw the tank cap back on. Start the saw and run it at no load for 2 minutes to gradually lubricate the chain with oil.
After completing all the stages of preparation of the makita uc4030a saw for work, gently wipe it from oil residues. Under no circumstances use mineral oils, otherwise you will have to breathe harmful fumes during work.
Convenience, ergonomics, grace and reliability
chain and blade lubrication required
Various models of such a device of the most famous brands were viewed on the Internet. The choice fell on the firm "Makita", although it cost more than the same saw from other firms (10,000 rubles). When I took this saw in my hands for the first time in the store, I realized that the choice was made correctly.
The elegant shape, good centering, comfortable and reliable hand grips that force the body to be in the safest position in relation to the cut, safety devices that increase the safety of work emphasized the high quality of the saw.The very shape of the saw clearly demonstrated the aggressive dynamics of the saw. I didn't want to let go of her.
Makita UC3530A in our store:
The Makita UC 3530 A universal power saw will come in handy on your home, garden or construction site. This model is distinguished by high performance, reliability and durability, and in addition to everything, it is very comfortable to work with. The saw is equipped with a quick-acting chain tensioner and bar removal device without the use of keys, which not only improves productivity, but also eliminates the need to constantly wear additional keys.
The Makita UC 3530 A electric saw is operated by means of convenient and intuitive buttons and levers. Due to its design features, this model is easy to maintain. The use of sealed ball bearings and a special lubrication system of the gearbox ensure long-term operation of the electric saw without specialized maintenance.
In order to increase the safety of the saw, the developers have provided in this model an inertial chain brake, which protects the user from accidental injury as a result of "kickback". This system ensures that the chain stops in a fraction of a second - even before the thrown tool can “overtake” the user and cause injury. To protect the network from overloads and to prevent premature wear of the mechanism, the Makita UC3530A saw has a built-in electronic system for limiting the starting current.
The Makita UC 3530 A electric saw is equipped with a powerful longitudinal motor providing a high cutting speed of 13.3 m / s. Due to the longitudinal position of the motor, the tool is compact and perfectly balanced. Comfortable rubber grips provide maximum control over the saw during operation. The saw is equipped with an automatic chain lubrication system (the capacity of the built-in oil tank is 0.14 liters), which prolongs the service life of the saw headset and the tool as a whole. Visual control over the lubricant level is carried out through a transparent sight glass.
Chainsaws are used today in a wide range of applications. This relatively simple tool is essential in everyday life for solving a wide variety of tasks. You can order the Makita UC3530A power saw in the Klondike online store.

Alexander what kind of grease do you use to lubricate the tool?
Greetings from Poltava! Sanya! Nice video! Definitely like! But let me make a small amendment: the armature and the rotor have significant differences. In this case, the word rotor is not applicable, but the anchor is just right! Take note and not to doc! Good luck!)))
Well, if you try to replace which brushes to put?
Alexander tell me which brushes to put on the BOSH 14.4 screwdriver and do they change them at all, and what are the standard ones?
Alexander, the better to lubricate the grinder gearbox and how long will the lubricant last?
Andrey Khmao special grease makita, 1/3 of the gearbox.
It is best that you sell spare parts for such tools. we don’t sit with fire during the day
Hello, I would like to ask you, I have a Chinese ROYCE drill there is no noise-suppressing capacitor, you can put an noise-suppressing capacitor on it, if it reduces the scaling on the scissors and heating) Thank you in advance
And what a yellow grease. You can name it)))))
Respect for vidos, and accuracy
Sasha ! With your help, I learned how to take care of the instrument and even repair it! Got up the courage and desire 🙂 my hands are in place. I am also engaged in apartment renovation (a talented person is talented in many areas). What I want to say about you. I have 1 question: where can I look at the lubricant on the gearbox (declared by the manufacturer), how to determine it using the Internet. Right now, the cordless drill makita 6347d (made in the usa) is on hand. I ordered a replacement button. It is only necessary to change the lubrication of the gears (it became a little tight from dust and darkened). Thanks in advance ! And thanks for opening my eyes to the instrument and caring for it (after you I bought aeg 13 xe balgarka, I fired up - I'm head over heels)
An electric jigsaw is sometimes a very necessary thing in the household. Those who like to do joinery and carpentry around the house will surely have this power tool. And for those who are engaged in repair and construction professionally, God himself ordered to have a jigsaw in his arsenal.
Modern jigsaws are able to cut not only wood, but also plastic and even metal. It is only necessary to install a suitable cutting tool for each material - a file. Replacing the file is not difficult. Using the hexagon wrench supplied with the tool, unscrew the screw holding the saw blade, install a suitable saw blade and fix it in the reverse order. There are also jigsaws with quick-clamping saw attachment.
In this article, we will focus on the Makita 4324 jigsaw. The author of these lines and also the owner of this model has used it in the mode of intensive loads for several years. This tool is very reliable, easy to use and also has a pendulum mechanism.
This mechanism allows the saw to move forward and backward, and vertical movement is provided by an articulated gearbox.The pendulum switch has three positions.
When the mechanism is off, the file moves only from top to bottom and back. When switching on, for example, the first position, the cutting tool also starts to move back and forth. And the higher the position, the greater the amplitude of the pendulum mechanism. Thus, when sawing wood materials, the chips are removed better and the cutting speed is increased.
One of the most common jigsaws malfunctions, especially with pendulum mechanisms, is the wear of the support roller. It often happens that the roller, due to heavy wear, simply falls apart into two parts.
It is not recommended to work with a broken roller, as the load on the gearbox increases. Therefore, the support roller must be replaced. You can buy it at the service center or buy it at the online spare parts store.
To replace the support roller, the jigsaw will need to be disassembled. Dismantling begins by removing the platform.
Having unscrewed the screw fixing it to the body with a hex wrench, the platform is removed together with the clamping bracket.
Then the plastic shield is removed. To do this, it moves down to the stop.
Then, using a thin screwdriver, it is pulled out of the grooves of the case.
Next, unscrew the screws that tighten both halves of the case.
Gently inserting a thin screwdriver between the halves, separate them.
Then the old support roller is removed and the axle is pulled out of it.
This axis must then be inserted into the housing of the new roller.
Having installed a new support roller in the tool body, we assemble it in the reverse order. Having connected both halves of the case, we tighten it with screws. Then the plastic shield is installed and followed by the installation of the platform.
You should always have one, and preferably a couple of spare support rollers in stock, if the jigsaw is used often and under heavy loads. The support roller is relatively inexpensive, and the normal operation of the tool largely depends on its condition.
Well, in the end, I propose to watch a visual video on the repair of a jigsaw.
