What kind of oil to pour into a jackhammer

Types and device of a jackhammer

The most popular classification of jackhammers is by type. There are bumpers with an electric motor, internal combustion engines, pneumatic and hydraulic tools.

Before we go into detail about the features of each type, let’s talk about the general features of the entire category. The jackhammer device includes the following components:

  • body;
  • rigging (chisel, lance, etc.);
  • impact mechanism;
  • tool holder;
  • reducer;
  • a pen;
  • start button.

How does a jackhammer work? Energy that originates in the engine or is supplied from the compressor pushes the firing pin. It transmits movement to the pike, which acts on the destroyed material.

In principle, hydraulic hammers are similar to pneumatic ones, except that instead of compressed air, they use a liquid, most often oil. Accordingly, such a tool requires special expensive equipment that will supply this fluid. This is the least common variant of bumpers, which is not found in everyday life.

Chuck type

The jackhammers use the SDS chuck. It can be of several types:

  • SDS-HEX. Hex shank that can be used to fit a variety of nozzles. chisels, lances, vanes, ramming nozzles, etc. Has a simple and secure hexagon type fastening.
  • SDS-MAX. The shank diameter has a diameter of 18 millimeters and 5 grooves. It is very difficult to break this shank, therefore it is suitable for heavy and long work.

Dnipro-M demolition hammer review

The assortment of our brand includes several models of jackhammers that are suitable for performing work of the most varied complexity.


By power, jackhammers can be divided into the following subcategories:

  • 900 to 1300 watts. A tool with this power rating can dismantle walls made of brick, stone or concrete.
  • Over 1300 watts. Demolition hammers with the highest power are suitable for professional work. demolishing asphalt, concrete, frozen soil, demolishing walls and even foundations.

The weight of a jackhammer depends on its power and capabilities. The lightweight tool will be easy to transport, you will be less tired when working, but it will not be able to complete all tasks. A heavy tool can handle anything, but it takes effort to work.

  • Lightweight jackhammers weigh from 6 to 10 kg. They are convenient to use for work at height and inside houses.
  • Average weight ranges from 10 to 20 kg. With their help, you can create openings in the walls, destroy partitions, etc.
  • Heavy jackhammers (over 20 kg) are not very suitable for household work and are more often used in professional activities, for dismantling monolithic structures, working with large volumes of concrete, granite, etc.


They are equipped with an internal combustion engine that converts gasoline into energy. These hammers are heavier and more powerful than electric hammers. They are self-contained as they do not have a power cord. Petrol jackhammers are very convenient to use where there is no way to connect the tool to the network.

Among the disadvantages are the need to refuel the jackhammer and pour oil into it, the presence of exhaust during operation.

What kind of oil to pour into a jackhammer?

Each manufacturer specifies the brand of oil that is suitable for its jackhammers. When buying a Dnipro-M breaker, you will receive gear and shank oil included.

What kind of oil to pour into gasoline for a chainsaw?

A special oil for two-stroke engines is used to prepare the fuel mixture. There are a great many of them today. However, manufacturers themselves, especially serious ones such as STIHL or Husqvarna, always write which oil to mix with gasoline for their chainsaws. They are produced under the same brand, so, for example, STIHL oil is suitable for a STIHL saw, and Husqvarna is suitable for Husqvarna.

At the same time, representatives of manufacturers declare that they do not know how the chainsaw will work with other oils, but they can definitely guarantee the correct operation of their equipment when the fuel mixture for it is prepared on the basis of the product that they indicate in the operating instructions. By the way, if a malfunction occurs in the piston group during the warranty period, you may be denied a free repair if it turns out that you added something other than what the manufacturer indicates.

At the same time, I recommend buying products from renowned manufacturers, the same STIHL or Husqvarna, as well as, for example, Echo, Hitachi, Makita.

The masters from the services with whom I had to communicate praise all the same STIHL and Husqvarna oils.

How to change the oil?

If the warranty period has already expired and you want to change the oil yourself, you must refer to the manufacturer’s instructions. The compartment where the grease for the hammer drill is poured is indicated there.

The inside is washed with a special solution or kerosene. In addition to the gearbox, replaceable couplings and a drill, other elements of the tool do not need lubrication.

A small amount of oil is applied to the indicated areas. There should not be too much or too little lubricant. In both cases, the result will be unsatisfactory. Further assembly is carried out in the reverse order.

Rotary hammer lubrication is extremely important. By choosing the right oil and changing it, you can significantly extend the life of your equipment. Without proper maintenance, the presented power tool quickly fails.

Due to the complexity of the design and high loads, this equipment is in dire need of the use of lubricants. It is necessary to select them very carefully.

Indeed, thanks to the additives contained in the oil, its viscosity, various qualities of such substances are provided.

Universal spare parts for a jackhammer that are suitable for all types of jackhammers produced by ZSO are:

  • Lance-pointed P-11, lance. chisel P-31, lance. blade P-41 (working tool): as a rule, hammers are not included in the package;
  • End spring;
  • Rubber bushing for a peak (not everyone uses it, although it extends the life of the spring and with it the peak breaks the barrel less);
  • Futorka;
  • Foot washer;
  • Nipple;
  • Union nut;
  • The spring is disc-shaped;
  • Drummer (the difference is only for the models);
  • BRS 3 / 4สบ (speeds up the process of connecting the jackhammer to the compressor);
  • A shock absorber under the handle (not all manufacturers install it, but we recommend it in addition to the handle spring);
  • Handle spring;
  • Handles (the difference is only for models);
  • Casing (muffler);
  • Retaining ring on the casing (muffler).

From the list it can be seen that the specified spare parts are almost 70% of the components of the jackhammer.

Repair of jackhammers “Hitachi”

One of the most common problems with a Makita bump stop is the lance getting stuck in the barrel. As a rule, the reason is the wear of the retaining bodies, but a banal defect of the peak is also possible.

In order to fix the problem, you must act according to the following algorithm:

  • Removing the top cover (protection).
  • Retaining ring is removed.
  • Dirt accumulations are removed.
  • The oil seal is removed (at this stage, the peak will fall out of the trunk).
  • The locking body is inspected. If it has obvious signs of wear (rounded edges), then it must be replaced.
  • Inspection of the splines of the barrel. They are normally square in shape. If they have a sharp shape, then the barrel requires replacement.
  • Worn item replacement and assembly.
  • Blockage in the hose. As a rule, it occurs due to a fracture. Fixing the problem won’t be a big problem. You just need to find the damaged area and remove it. Unfortunately, if the removal of a part would cause the hose to be unnecessarily shortened, it will have to be replaced completely. The list of tools to fix this problem is minimal:
  • knife;
  • clamps of the appropriate size.

How to choose tool oil?

Experts advise purchasing grease from well-known manufacturers. They have proven themselves well in the market. The quality of such products is confirmed by years of conscientious work of technology.

Hammer Lubricant for Bosch, Makita, Hitachi, etc. is available with a wide variety of component oils. Through scientific development, such manufacturers are constantly improving the quality of their products. They fully comply with modern requirements.

Experts point out that such products can improve the quality of work of even rather mediocre equipment. The viscosity grade of the oil must be correctly determined. The quality of the work performed by the equipment and its durability also depend on this.

High-quality domestic products

Today, the Russian and foreign markets are more and more conquered by oils for power tools of domestic production. Lubricant for the Interskol, Zubr perforator not only has a low cost, but also fully meets modern requirements. A wide assortment and constant laboratory control allow manufacturers to maintain a leading position.

The products are delivered both to neighboring countries and to Europe. These are high-quality, modern products. A wide range of models will allow you to choose the grease that best meets the technical requirements.

But if a breakdown does occur, then there is no need to despair, the hammer can be repaired without spending a lot of time and money.

The versatility of many jackhammers. in particular, the production of such factories as TEMZ (Tomsk Electromechanical Plant named after Vakhrushev), TZK (Tomsk Kuznetsov Plant), ZSO (Construction Equipment Plant in Uglich) allows you to replace parts at the workplace and for this you do not need to be an engineer with higher education, but you just need to know the order of disassembling and assembling the hammer.

Any pneumatic jackhammer is practically a Kalashnikov AK-47 assault rifle. trouble-free and reliable.

Air Tool Lubricator Lubricator

I found that you need to drop a cube of oil into the hose before starting work. Question: If I unscrew 2-3 small nuts, do I need to drip oil there the next day or again a week later? Wouldn’t it be overkill?

This wrench copes with its task perfectly. There is enough receiver. The compressor turns on for 20-30 seconds no more than 4 times while I disassemble the motor to the screw:

Functions of lubricants

Probably the tools responsible for chiselling, drilling, sawing and cutting building materials need lubrication. The reason is simple. fine dust, not particles of a wide range of substances, enter the gearbox on the tool tool, increasing friction between its moving parts. So that your tool does not fail and last years, not months, you will need regular cleaning not grease for Makita drills, but also lubricant for gearbox parts, which will significantly reduce wear of parts.

There are several types of technical grease, not, you, grease for Makita differs in its properties from grease for a drill gearbox. Often, liquid technical oil acts as a lubricant. it is poured into the gearbox housing does not spread evenly between the parts.

Makita Drill Lubricant is your grease. under such circumstances as oil is formed from a mixture of technical oils of a non-specific thickener, has a high penetration ability does not reduce friction between parts. The grease released by Makita protects tools from corrosion, repels water, does not increase the mechanical stability of moving parts, almost no oil separates during its operation.

Repetitive oil change in the gearbox is very important, not only as recommended by the manufacturer, but also for a number of other reasons. For example, in the process of using a walk-behind tractor, foreign iron particles are formed in the oil that is in the gearbox.

They appear from friction and contact of the components of the walk-behind tractor, which gradually crumble, and all this iron crumb gets into the oil. Thus, the oil begins to thicken, which leads to unstable operation of the walk-behind tractor, in the future, and to wear of the gearbox.

That is why, a timely change of oil in the gearbox is a necessary preventive measure to avoid repairs in the future.

Indeed, it is much more logical to spend the amount during one thousand rubles on the purchase of gear oil than to spend a lot of money for expensive repairs, as it is also called a complete change of the gearbox.

Self-made trailers for a walk-behind tractor are very popular, which they do by hand.

How to fill?

Before pouring new oil into the gearbox, it is necessary to drain the old water. In a similar way, the oil in the gearbox of the Salute walk-behind tractor is carried out, the video of which can be found on the web, as well as other models of walk-behind tractors.

Preparing Your Jack Hammer for Use

The method of action, in this case, will be as follows:

  • a single-axle tractor must be installed on a hill so that you can simply drain the oil from the gearbox.
  • There are two plugs on the gearbox. a drain plug, which is located at the bottom of the gearbox, and a plug that closes the oil filling hole. We first unscrew the filler plug located on top of the walk-behind tractor body (at the checkpoint).
  • We take a fairly capacious container (an ancient bottle of gear oil is suitable), then we substitute it under the drain plug of the gearbox.
  • Carefully unscrew the drain plug, after which the oil will begin to flow into our container. After waiting for the oil to completely drain, we twist the drain plug back. Then we tighten with a spanner wrench of a suitable diameter in full.
  • We insert the funnel into the filling hole. Then we take a suitable gear oil to be able to fill the gearbox.
  • After filling the gearbox to a rational level, we twist the plug back. This plug is equipped with a special dipstick, and its length is approximately 10 cm. When we filled in oil, we need to check its level. For this purpose, we twist this plug-probe for you, then unscrew it again and check.
  • If the oil is at the tip of this dipstick, then you will not just refill.

You, the oil change function, must be created by someone for 100 hours of operation of the walk-behind tractor. Occasionally, this function needs to be created by someone 50 hours.

In other words, the frequency of oil changes depends on the model of the walk-behind tractor, therefore all the necessary information is in the accompanying documentation for the walk-behind tractor.

What Oil To Fill In The Vibratory Plate Engine

Oil in the gearbox of the walk-behind tractor is the key to successful work

The presence of a walk-behind tractor in a personal household does not surprise anyone, because this technical device has been understandable since Russian times. Thanks to him, it became possible to have a fast and high-quality cultivation of the land, which took about 30 years quite a long time, and of course took a lot of energy.

But in order for your single-axle tractor, which is called, to serve for you regularly, often plowing the land and fulfilling the rest of its purpose, it is necessary to operate it in the correct way.

Namely, you need to know how much oil to fill in the gearbox of the walk-behind tractor, so that it works in a rational mode, and its parts do not wear out due to the lack of the necessary lubricant.

By and large, all the necessary information, usually, is indicated in the operating annotation for a specific model of the walk-behind tractor, where the brands and grades of recommended oils are directly indicated.

But, there are cases when a single-axle tractor is purchased used, or by another method, alas, the point is that such motoblocks are supplied, in the main, without any annotation.

You will like a person more in confusion, not knowing what kind of oil is poured into the gearbox of the walk-behind tractor, therefore it is useful for him to know about its main types, as well as the methods of pouring into a uniaxial tractor.

Choosing the type of lubricant

The correct gear lubricant is specified in the manual for the power tool, but if this manual is not available, select a gear lubricant recommended by Makita. The use of engine oil, as it is also called graphite grease, you should also know: only a specialized grease for a Makita jackhammer can reliably protect your tool from corrosion and not reduce wear of parts; other lubricants will only partially reduce friction between parts.

Often, the use of commonly available lubricants leads to excessive heating of the gearbox, and their service life cannot be compared with the operating life of a branded lubricant. Today, only Makita-supplied gear lubricant is suitable for cordless models. just like oil will adequately protect your tool from braking and not overheating.
