Lubricant for the Makita 2450 peorator gearbox

Greetings on my site! This article will talk about the lubrication of the penetrator. The operation of this tool requires not only a simple careful attitude. Be sure to periodically lubricate the gearbox and cartridge.

At the same time, the gearbox, of course, is already coming from the factory. But over time, the lubricant leaks somewhere, somewhere dries. In addition, it is intended only to reduce friction, and not to eliminate it. Therefore, one way or another, and the details still rub against each other, which is why fine metal dust is gradually formed, which remains in grease.

As a result of such mixing of metal and lubricating material, the properties of the latter are gradually lost and the wear of the parts is accelerated.

Inexpensive Chinese peorators can be poorly lubricated at the factory. Experienced masters of service centers recommend after buying even a new such device to immediately disassemble it and miss it

The cartridge from the plant goes dry. Here, in fact, not the cartridge itself is smeared completely, but only its place, which is in contact with the drill, since it is in it that severe friction occurs, without reducing which the cartridge itself and the tail of the drill itself can be damaged.

So, below, consider how and how to lubricate these elements. The SDS peorator with the horizontal location of the engine will be considered, since it is they who in the vast majority of cases are used by home craftsmen, and the article is mainly written for them.

How to lubricate the peorator

Different types of lubricants are used to lubricate the gearbox and a cartridge with drill.

Lubrication for the gearbox

A special lubricant is used here, which should be called. gearbox. It can be like under the brands under which the pies themselves are produced. Makita, Bosch, Aeg, etc.D.

But it can also be released by a company that is engaged in this type of product, for example, Ravenol, Shell, XADO, etc.

Some use simple lilet or salutol for these purposes. But compared to special lubricating products, they dry faster, and they do not eliminate friction as it should.

Lubrication for drills

Everything is exactly the same here. Special lubricants for this purpose are called. for drills. And are also usually produced by the same firms that are done by peorators.

For lack of special lubrication, you can use graphite. But it does not so well remove the heat from the shank, but this is important, since sometimes with prolonged work the shank happens and is flattened, which is why it is difficult to extract later.

The appointment of pneumatic jack hammers

• construction work of various types, including the destruction of brick or concrete structures, walls and structures, other dismantling work of varying degrees of complexity;
• The formation of road surface. fragmentation of solid soil, destruction of asphalt;
• Mining industry.

The advantages of pneumatics can also include: high reliability, durability, ease of use and significant low cost of construction.

These criteria today make a pneumatic tool attractive, especially compared to its electric counterparts.

The only drawback of the pneumatic tool is its clear attachment to the compressor, which pumps air under pressure.

Device and principle of operation of pneumatic hammer

By constructive features, this instrument belongs to the category of piston pneumatic systems equipped with a distributor of air with an impact principle of action. The pneumatic hammer is enacted due to the influence of the stream of compressed air supplied by the compressor.

The main structural elements of the tool are:

• Lever arm.
• Shock absorber.
• Spring
• valve
• Stop ring
• Part of the body
• Drummer or drummer. This is an air distribution shock mechanism
• Buffer spring
• nozzle
• Nipples.

In general, pneumatic hammers consist of several main components:

• The handle of the body. includes a trigger, silencer and body. The silencer is used to suppress aerodynamic noise that occurs as a result of the exhaust air from the hammer;
• Protection against vibration pen. provides the tool with glass with two sealing bushings;
• anti.vibration protection against chisel. includes a spring.loaded sleeve and a manipulator;
• Shock assembly (trigger). consists of a barrel, air distribution systems and a blow.

The shock system performs a number of basic functions:

• provides air supply to the device with its subsequent distribution between the blocks of the shock element and the removal after use from the general equipment system;
• Transfers the energy of the used air to the mechanical operation of the main working element. drummer.

By the way for those who are interested, that’s what I managed to find out. And I see, I have already written a desa, not Sixty but 25-30 mothers.

To prevent dust from flowing oil, this power tool has a hermetic structure of the stem part. For this reason, myth jackhammer

It is used along a long time without the need to replace or add oil. After initial start.up, add the oil each Twenty Five (motorcycle) hours. one. To fill the oil, turn on the machine so that the oil does not work for a certain time do not warm up. 2. Turn off the power tool do not remove the cable cable from the outlet. 3. Unscrew the lid of the tank for oil (10), using a special key. four. Pour oil in the volume g. Use specialoil “Mobil Delvac MX” SAE 15W-40 viscosity. Not semi-synthetic non-synthetic motor oils have a index corresponding to 15W-40 are used.

Not served, as then the need to replace the mothers? NOT a plug for oil? There are already on the forums that they have already sold a flooded, full crankcase from the store, so it dries from the hydraulic shock. The oil was leaked began to work normally. This is normal in your opinion? Clause 5.8 no I did not see, and it is necessary to sell such information with bold font, write with three exclamation signs. And about the manufacturer, on the request your site was presented. Once you trade, then you also do not answer for the goods for the goods. But call the SC yourself that you would not dream of know. You are listened to, listened to you. Well, what a certain number of times, until the tongue is braided. Then it turns out that the specialist is gone today, it will only be tomorrow.

Question to manufacturers, and instructions for the hammer to write normal, laziness was to sell? Why should I guess, there is no oil there. Why do you have about completely different two hammers of the M-30 not M-25 one instruction. Even in the store they don’t know who says 100g who 200g. Who says it does not follow at all. Spoil your reputation with such an attitude to the consumer.

Lubrication for an electric jack of hammer

An electric jack of a hammer is a tool that has a rather reliable sealing, since its work is designed for extreme conditions. Lubrication can not be replaced for a rather long period of time even with the active operation of the tool.

When the time has come for replacement, it is made according to the following algorithm:

• An important point! Safety: Before you start the replacement procedure, turn off the tool. Make sure the plug is not in the outlet to avoid electric shock.

• A crank mechanism is removed, after which it is necessary to remove the old grease.
• Introducing new lubricants in the amount of 30 grams.
• Install the casing of the crank mechanism in place.

Electric junk hammer is far from the most difficult tool. For its long.term work, minimum maintenance and attention is necessary. The list of problems in the work is quite limited, with the main part of them you can figure out the article.

The drill bar has the following parts: body 1 made of twisted steel, head 2 with a nest, into which the shank 5 removable incisor 4 is inserted, and the shank 3, which is inserted into the cartridge of the spindle of the drilling machine.

For manual electric wood, rods with a round shank that have a sector cut at the end are used, and for column electric wood. with a rhombic shank.

Peorator and its internal device

Peorator, this is a tool that is familiar to almost everyone who at least once made repairs at home. Outwardly it is very similar to the drill and the functions of the same, the production of holes. The difference between the tools is that the drill crashes into the hole due to the pointed edge of the drill, while removing the chips, and the peorator pierces the hole, as if with a chisel. Therefore, the power of the penetrator is indicated in the joules and is called the energy of the impact. According to this indicator, they choose the tool, as well as by engine power, if it is electric.

To get a blow, you need an impulse that creates an electric or pneumatic engine.

For the proper use and maintenance of this tool, you need to at least superficially know its device from the inside. Of course, at present, many manufacturers have mastered the release of this tool, but its general scheme has remained unchanged, with the exception of some modifications, since 1932, when the first power tool appeared. By the way, the first was the pneumatic peorator, which was invented specifically for work in mines in 1851.

The tool, as shown in the figure, consists of an electric motor (if it is an electric drive), a gearbox, which, together with a safety coupling, regulates the number of revolutions and an impulse, a shock mechanism and a fast.packed cartridge of the SDS Max or Plus system. The gearbox has a gear, which should be lubricated for good trouble.free work. Also, a kit of bearings in the shock device also needs lubrication.

The remaining devices that are in the penarator are called additional. This is the operating mode switch, a mechanism for fixing the inclusion button, reverse, as well as devices such as anti.vibration, removal of dust during operation, fixing the depth of work, adapters for the cartridge and more. they may be present or not. It depends on the model and manufacturer.

Poorator maintenance

Like every tool, the peorator needs to have the right care.

The tool does not belong to the category of cheap, therefore, on time, the maintenance made will allow your tool to serve for many years. over, the peorator requires this more often than any other tool. Remember in what conditions this tool works. Dust, vibration, nozzle bite into concrete or brick reciprocating. progressive movement.

As mentioned above, the internal details of the gearbox need lubrication so that there is no friction between them. At the same time, lubricating them once, this is not enough. Particles of dust fall into the oil through the technological holes, and it itself becomes different, while the dust in it becomes as if an abrasive, which helps the rapid wear of details. Therefore, so that the tool is longer in working condition, it must be periodically inspected and greased.

Greetings on my site! This article will talk about the lubrication of the penetrator. The operation of this tool requires not only a simple careful attitude. Be sure to periodically lubricate the gearbox and cartridge.

At the same time, the gearbox, of course, is already coming from the factory. But over time, the lubricant leaks somewhere, somewhere dries. In addition, it is intended only to reduce friction, and not to eliminate it. Therefore, one way or another, and the details still rub against each other, which is why fine metal dust is gradually formed, which remains in grease.

Frequently asked questions about chipping hammers

What is the difference between a junk hammer and a peorator?

The jack of it is different from the peorator in large sizes and weight, power and increased capabilities. Unlike the peorater, the jackhammer is able to destroy several tons of concrete or other materials per day, and also shows a higher pace of work.

What kind of oil to pour into a jack of a hammer?

Each manufacturer indicates the brand of oil, which is suitable for its jaws. When buying a Dnipro-M chipping hammer, you will get oil for a gearbox and a shank in the kit.

How to lubricate a jack of a hammer?

Before inserting the nozzle into the cartridge, you need to lubricate its shank grease. This will provide a good sliding level during operation and reduce the level of heating.

Jumping hammer with a hexagon 28.6mm Makita HM1317CB

After selecting the impact force, you need to carry out preparatory manipulations with a jack of a hammer. Jumping hammers of various capacities are distinguished by the design.

We draw your attention to the fact that any decent manufacturer of professional jack hammers makes pens with anti.vibrational dungeons that protect your joints from injuries and occupational diseases.

If there is no anti.vibration handle in the design, we recommend that we refuse to use this technique. Otherwise, you will deal with cheap production.

What is a jack of a hammer, the principle of its action

The device is a percussion tool designed to work to break and split rocky sedimentary rocks, concrete structures, asphalt, etc.D. The hammer is controlled by the operator manually, the direction of the impact, frequency and duration of exposure to the processed surface is regulated. Since the force exposure is transmitted to the working body (peak, spatula, chisel, etc.P.) from the box driven by third.party energy source, the device belongs to the mechanized class of tools. The drive can be

The number of shocks varies from 15 to 45 Hz. (t.e. 15–45 working movements of the box per second).

In addition to manual chipping hammers, there are easel machines using a similar principle of operation. They are used in the development of rocks in mines and open quarries. The inventor of the machine tools is considered French engineer Droen Sommeye (late 50s of the 19th century).

Mobile jack in mine drilling

The chipper device

Despite the variety of species, their principle of action is no different. The working part is a chisel, peak or fucking shoulder blade. This is usually made of high.strength steel hexagon, pointed at the end. It is driven by a combat that receives an impulse from the drive mechanism. Battles and piston are installed in the sleeve. There is a airspace between them, which is compressed, pushes a fight towards the peak. This design is necessary so that the destructive force does not have a direct application to the drive mechanism. Otherwise, hit 30-50 kJ. quickly destroyed the engine rod. During the reverse passage of the piston, a low air pressure forms inside the sleeve, which “draws” the fighting into its original position and the cycle is repeated again. Regardless of the constructive solution of the drive, the mechanical part of the chipper remains unchanged.

How an air chipper works?

The principle of operation of an electric jack of a hammer, tool repair

Jumping hammer is a tool designed for heavy loads. Nevertheless, he is not safe from breakdowns. Consider some of the most common problems of the work of electrical hammers of manufacturers of Makita and Hitachi manufacturers.

Repair of electrical jack hammers with your own hands

Repair of an electric jack of a hammer is a difficult task. In order to fulfill it, you need to understand: as a rule, the repair of the hammer consists of two main stages:

Of course, it will be more correct to repair the electric hammer that needs it and contains a certain stock of working resource. This must be determined so that the repair does not turn into a useless waste of time, effort, money, and the tool after repair has worked out a certain period of time.

Important! If the jack of a hammer is in a deplorable state, then its repair is extremely disadvantageous. for spare parts (SIPs) are quite high, and expenses on them will put the profitability of the repair by question.

Remember! In order for the tool to do not remind yourself of breakdowns as long as possible, its maintenance must be carried out regularly. This does not need special devices. As a rule, disassembly of a jack of a chip is possible in the presence of a rather limited number of tools.

The market provides a limited list of SIPs. As a rule, these are springs, valves, air distribution nodes, brisk. Therefore, not every breakdown can be eliminated without contacting the service. Nevertheless, some problems that can still be solved with your own hands, it makes sense to consider.

Interesting! A positive moment. Many ZIPs for jack hammers that can be found in the market are universal. That is, one spare part is suitable for several models of hammers, which are different not only with power, but even by the manufacturer.

It will be correct to note that if you take into account the Chinese electric hammer, then in case of its breakdown, you should not count on successful repairs. They are often disposable due to the low quality of materials used in the manufacture.

Consider the classic plan of repair work:

• Work of disassembly and cleaning of contaminants from the jaw.
• Identification of the defect (if it is unobvious).
• Repair or replacement of damaged parts.
• Assembly of the tool.
• Checking performance.

As a rule, highly qualified services of services who are engaged in this professionally use this plan.

We consider the possibility of repairing with our own hands, and, as a rule, this moment comes when the problem is obvious and requires an immediate solution.

So, let’s consider the several of the most common breakdowns of electrical jack hammers for models of giants of “Makita” and “Hitachi” giants, which can be performed with your own hands.

Repair of chips “Hitachi”

One of the most common problems with the Makita chipper is peaks in the trunk. As a rule, the cause is the wear of the locking bodies, but the banal defect of the peak is not excluded.

In order to eliminate the problem, it is necessary to act according to the following algorithm:

• The upper cover is removed (protection).
• The stop ring is removed.
• Cloudy mud is removed.
• The oil seal is removed (at this stage of the peak it falls out of the barrel).

• Stop body is being examined. If there are obvious traces of wear on it (the edges are rounded), then it must be replaced.
• Inspection of the barrel slots. In normal condition, they have a clearly square shape. If they have an acute shape, then the barrel requires a replacement.

• Replacement of a worn element and assembly.
• Cabbating a hose. As a rule, it occurs due to a fracture. The elimination of the problem will not be a big problem. You just need to find the damaged area and remove it. Unfortunately, if the removal of the part leads to excessive shortening the hose, then it will have to be replaced completely. The list of tools to eliminate this malfunction is minimal:

• knife;
• Clamps of the corresponding size.

Repair of chips “Makita”

Often there is a problem of increased frequency of shocks with a weak single strike.

Reason: an overstated gap between the adoptive device of the barrel and the distributor.

• Disconnect the hammer and muffler.
• Remove the locking ring and fixer.
• Wind the link to the “dead” point.
• Despite the reliability of the tool and the efforts of the manufacturer, there is often a problem with the uniting node of the trunk end and valve box. The problem is eliminated if you clean the node in time.

Lubrication for an electric jack of hammer

An electric jack of a hammer is a tool that has a rather reliable sealing, since its work is designed for extreme conditions. Lubrication can not be replaced for a rather long period of time even with the active operation of the tool.

When the time has come for replacement, it is made according to the following algorithm:

• An important point! Safety: Before you start the replacement procedure, turn off the tool. Make sure the plug is not in the outlet to avoid electric shock.

• A crank mechanism is removed, after which it is necessary to remove the old grease.
• Introducing new lubricants in the amount of 30 grams.
• Install the casing of the crank mechanism in place.

Important! Studying the requirements for the replacement of lubricants, you need to pay attention to the oil. Oil replacement in a chipping hammer is not needed.

The exception is the situation of damage to the integrity of the tool that led the leakage of the oil. In such a situation, the repair production is independently strictly prohibited.

Since if it is possible to return the tool to working condition, then its use will be dangerous.

Instructions for the use of pneumatic jack hammers

The hammers are designed to loosen hard and frozen soil, fragmentation and removal of old asphalt coatings, punching openings and holes in the brick walls of buildings, disassembly of brickwork, chipping coal of various strength and other similar works.

Security measures

The vibration levels of the hammer do not exceed the values ​​regulated by GOST 17770-86.

Instructions for the use of the pneumatic jack of IP-4613Mo and its modifications

Preparation of a pneumatic hammer for work

• To prepare a pneumatic hammer for work:
• unscrew the end spring;
• Remove the plug 28 from the barrel;
• Wipe the shank of the working tool and insert it into the end spring, and then into the barrel;
• wind the end spring on the barrel;
• Scroll the united nut on the fitting until it stops;
• Remove the plug 22 from the nipple and pour 30 g into it. kerosene, having previously pressed the handle;
• select the hose of the required diameter, blow it, put on the nipple and fix it;
• Connect the air supply hose to the highway;
• Open the valve and put the hammer into the work by pressing the handle for 1-2 minutes;
• Disconnect the air from the highway with the valve and disconnect the hose from the hammer, unscrewing the united nut from the fitting;
• pour lubrication into the fitting according to the table.3;
• Assume the hose to the hammer, screwing the united nut on the fitting until it stops.
• Install the hammer with a working tool on the processed object and put it into the work.
• When jaming a working tool in the destroyed material, it is forbidden to make efforts to the hammer leading to the stretching of the end spring. When stretching the spring for this reason, the hammer for warranty repairs is not accepted.

Maintenance

• To ensure the normal operation of the hammer, follow the rules set forth in this passport.
• The cyclic mode of operation of the hammer provides for two types of service. a daily and periodic.

In accordance with the proper instructions, the air supplied to the pneumatic hammer should have a cleanliness of at least 5 class of contamination according to GOST 17433-80 and contain the industrial oil I-20A GOST 20799-88 about the amount of 3-4 drops per 1 m3 or other lubricant, in its properties not inferior to the indicated. The equipment recommended for air preparation and its installation scheme is given below.

Pneumatic installation of air preparation equipment

1-filter-moisture separator; 2. reduced pneumatic cell; 3 (1), 3 (2). a manometer of excess pressure with the upper limit of measurement /, 0 MPa (10 kgf /cm); 4. oil sprayer; 5. Drown valve.

Air preparation equipment should provide nominal throughput of at least 2.0 m3/min.

• Periodic maintenance provides for disassembling the hammer once a month in order to clean its parts from rust, dirt. To do this, wash all the details (with the exception of rubber parts) in gasoline or kerosene, wipe with a clean rag dry and grease according to the table.3. Then collect a hammer.
• Only qualified workers should be allowed to disassemble and assemble the hammer. In order to avoid the breakdowns of the pusher 16, disassemble the hammer in the following sequence: turn out the fitting of a glass; clicking on the handle, drown a pusher and.Turning the handle around the axis 30 °. 45 °, remove it from a glass.
• With prolonged breaks in the work, the hammer must be stored in a room with a temperature of 5 ° to 25 ° C and a relative humidity of no more than 70 %

For these conditions, pour 30-50 g through the starting device in the starting device. K-17 canned oil according to GOST 10877-76 and once turn it up shortly at a minimum pressure of compressed air.

Under other storage conditions, the hammer must be preserved.

Technical characteristics of the hammer of the chipped pneumatic IP-4613o and its modifications

Note: the hammer retains performance when reducing air pressure to 0.3 MPa.

Device and principle of operation

The hammer consists of a barrel 2 with a shock.mobile shock 9. On the upper end of the barrel there is an air distribution device consisting of a saddle 5, valve boxes 6, valve 8, a plate spring 11, cover 7, fixed from a thundercropolita 15 with pins and a trunk with a glass of a glass 1.

In the housing of the glass 1 is the launch device. It consists of a pusher 16, ball 26, springs 14, bushings guide 27.

A fitting 17 is also installed here with the nipplele 19 and the pitch nut 18 to fix the air supply hose. The glass is fixed from the thunder on the barrel with a stop 23.

Stop in the trunk and groove of the glass is held by the latch 21. On a glass of a fitting, handle 3.

A spring 13 is installed between the glass and the handle. On the trunk outside there is a casing 4 to remove the spent air, jamming of noise and the prevention of dirt from the exhaust holes inside the barrel.

A sleeve 29 is pressed in the lower part of the barrel, in the hole of which the shank of the working tool is introduced. The working tool (peak) 30 is fixed in the axial direction of the end spring 12.

When pressed on the handle, the pusher 16 moves in a glass of a glass and, drowning the ball, opens the access of compressed air through the nipple, fitting and a hole in the glass to the air distribution device.

Thanks to this device, the air enters alternately to the upper and lower parts of the barrel.

Under the influence of compressed air, the drummer makes reciprocating movements and strikes the shank of the working tool.
