In addition to the drill, it is necessary to Lubricate the cartridge. First, it is cleaned of old oil and dirt. Then, as indicated by the manufacturer, the amount is applied to the surface. Replaceable drill bits require a similar procedure no less than storms and drills.
Before each installation, the shank is machined accordingly. Studying which lubricant for the hammer drill and its chuck is more suitable, it is necessary to consider all the proposals from the manufacturer. If there are none, you should give preference to trusted manufacturers.
They reliably protect the chuck from premature wear. The additives included in the substance reliably absorb dirt, dust and prevent the destruction of working surfaces.
Leakage of grease from the puncher body, the puncher spits out grease. What to do?
Periodically to forums on the Internet and service centers of the company Successful technique Service Owners of the power tool contact with complaints that grease is flying out of the Makita HR 2450 hammer drill, Interskol and Elitech of various models or devices Other popular brands.

What kind of lubricant to use?
There are no universal greases, which are suitable for use in all units of the device, and cannot be due to the specifics of their operating conditions. The dimensions and tolerances of surfaces, rotation or sliding speeds, direction and magnitude of loads are taken into account.
The need for lubricants with different consistencies and other operating parameters.
The main properties of the lubricant
Lubricant for hammer drills Makita, Hitachi and many other manufacturers fulfills the required functions. Initially, it flows around the necessary parts of the mechanism, preventing their surfaces from rubbing against one another. At the same time, accordingly, their wear decreases.
Such substances can have additional additives that prevent corrosion. The second not less important characteristic is the washable function. During the operation of the equipment, small particles of material and dust can get into the tool. They settle on the mechanism and lead to its failure.
The grease collects this dirt and debris and keeps them in suspension. When too much contamination accumulates in it, the substance will need to be changed. There are mineral, synthetic and semi-synthetic lubricants. The most inexpensive substances are made from petroleum. These are mineral varieties. They quickly lose their properties and require frequent replacement.
Synthetic lubricants are expensive but of the highest quality. They do not need to be changed often, they provide the highest quality protection of the mechanism from wear.
Semi-synthetic oils of average cost. They have better properties than mineral varieties. But even in synthetic materials they fall a little.
Rotary hammer lubricant. Properties and purpose
Concept drill lubricant combines many different substances designed to form a resistant layer between rubbing surfaces in order to reduce the coefficient of friction. This reduces the influence of the phenomena inevitable during friction: braking, mechanical wear, heating.
However, a substance used for a long time itself begins to pose a hazard to interacting surfaces. It absorbs small particles of material from rubbing mechanisms, external pollution. This not only reduces the viscosity of the lubricant, but also practically turns it into an abrasive. As a result, the principle of action is reversed.
To avoid this kind of trouble, you should periodically replace the used product with a fresh one during the maintenance of the tool. The frequency of maintenance is set by the manufacturer and is regulated by the documents attached to the tool, as a rule, the Recommended type and brand of lubricant is indicated there.
Many people mistakenly believe that overheating of the unit during operation signals the need for replacement. This can be partly confirmed only if this phenomenon is systematic. In most cases, overheating is caused by an uneven distribution of funds between parts and an insufficient amount of it at a specific point in time in a given node. It is enough just to change the operating mode of the punch (from drilling to chiseling or vice versa) and let it run a little idle.
Common punch breakage
In addition to those listed, all other breakdowns of the hammer drill are usually associated with the failure of one of the following parts: gears, starter, bearings, mains connection cable, switches. In order to solve the problem, it is enough to purchase and replace the failed part.
- Useful tips for construction and renovation
Having decided to start repairs, it is worth worrying about the choice of the necessary tools and materials in advance. When carrying out repair work, it is often necessary to make a hole in wood, metal or tiles using a punch, to which you need to have a drill.
Take the punch and make sure it is working, to do this, insert the plug into the outlet, put the punch into drilling mode without a fight (extreme left position) and press the start button. A smooth sound without failures and jerks indicates the serviceability of the instrument. By purchasing a chuck suitable for your hammer drill model. If you do not know or are not sure which chuck will fit your model of rock drill, then it would be best to take a rock drill with you and try them on the spot for compatibility. To optimize performance and reduce wear, Lubricate the rotary hammer with Specialized Lubricant. To do this, open the tube of grease and dispense a small amount into the hole where you insert the borax. Then rest the punch with the handle on the floor or other hard surface on which it will be convenient for you to work, pull down the bottom of the head of the punch, insert the chuck and return the bottom of the head to its original position. Insert the drill into the chuck and, turning the top of the chuck clockwise until it stops, clamp the drill. Check if the drill is loose. If the drill moves, tighten the chuck further. Plug in the hammer drill and press the trigger several times, allowing the grease to disperse into parts. When checking the operation of the hammer drill, under no circumstances touch the rotating parts of the tool, otherwise you may get injured. For the same reason, install the drill chuck and drill only with the plug disconnected from the mains. If you buy a chuck just to make repairs at home once, then you should not choose an expensive model, the cheap option is enough for you. At the same time, it is not worth saving on a drill, a good drill will last longer and drill is much more convenient for them. Perforator. A tool often used in repair work of all kinds. How to choose and operate it? Using a perforator, they make nests and punches in ceilings and walls, and also remove old plaster and cladding from walls and floors. But, probably, the hammer drill is most often used to make holes in concrete surfaces. The tool can be powered from the mains or battery. Models of hammer drills with an electromechanical hammer mechanism are inexpensive. But models with an electro-pneumatic mechanism will cost more. In addition, the electro-pneumatic impact can drill even the most durable reinforced concrete. Have you already chosen a tool? Does the selected model have a chiseling function? After all, any puncher can drill a hole, and hammer out comments. This feature is most often available on hammer drill models with the non-spinning impact. Torque is important for a rock drill. Simply put, the higher the torque, the better. After all, this helps the drill to overcome great resistance and makes it possible to make holes in a wide variety of materials. If you are punching a hole, it doesn’t put pressure on the hammer drill as it does with a drill. The hammer hammer mechanism can create the required force by itself, and the pressure can ruin the tool. Do NOT chise often. It puts a lot of stress on the rock drill. Chiseling should not be more than 25-30% of the total operating time of the tool. If the engine is on, then it is not worth changing the operating modes of the rock drill and the direction of rotation. No repair, no construction is complete without the use of a hammer drill: this tool is used to drill, drill and is used for hammering work. To make your rock drill last longer, it is important to know how to operate it correctly. This tool is used to work on concrete, brick, stone, metal, and is also used as a conventional drill and jackhammer. They can drill any holes, remove old tiles, break floors or walls. The hammer drill has an impact mechanism. Electromechanical or electropneumatic action. To turn it on, you need to press the button. The main disadvantage of rotary hammers. This is their considerable weight: there are specimens weighing more than 25 kg. For the convenience of work, you can attach an additional handle made of soft material, this will reduce the intensity of vibration.
Lubricant for used rotary hammer
The drill works in the most severe conditions, it perceives shock, tangential, thermal and other loads. Obviously, the impact of such conditions can quickly destroy both the brown material and even the Landing site. Punch drill lubricant is used to prevent overheating.
Before you lubricate the storm perforator, you must clean it from dust, dirt and second foreign particles. The application process itself is very simple. The substance is applied in an even layer over the entire work surface.
How to lubricate a punch and what is needed for this?
Usually many users have a question. How Often Should You Lubricate the Rotary Hammer? After all, the intensity of use is different for everyone. Someone works with a puncher once a year, while someone constantly uses it for various jobs. Professionals advise looking at the magnitude of the loads, as well as the recommendations in the instructions. In this case, be sure to consider whether the warranty period of service has passed.
The second question appears to users. How to do it yourself? For example, the warranty period is over, or you just want to do some work at home. Modern devices have a special compartment where oil is poured. As a rule, the instructions say exactly where this hole is located. There should also be a disassembly diagram. The amount of oil that is needed is placed there (this is indicated in the instructions). However, before doing this, you need to flush the crankcase with engine oil or kerosene. In the event that there is no special hole and the device needs to be disassembled, you can additionally blow it.
[Page = 1] [/ page] Only after flushing and blowing is the lubrication started. There is no need to lubricate the transmission clutch and other areas that do not need oil. In addition to the gearbox, if necessary, you can lubricate storms and other replaceable nozzles. Suitable for this Lithol. In the event that there is an open cartridge in the device, the oil seal can also be lubricated. It is only important to apply a small amount of oil to these areas. This can be done before each attachment is installed. After removing it, be sure to dust the shank.
Lubricant for a perforator lithol or solidol is purchased at any construction supermarket. You can also find branded oils there.
How to lubricate the punch chuck?
Cartridge. Part of the instrument most sensitive to the remnants of old dirt. Deposits of used materials can cause significant wear on rotating surfaces, therefore, before changing the lubricant, the cartridge is thoroughly washed with aggressive liquids: kerosene, acetone, solvent, etc.
Chuck grease can be selected based on two principles:
- Read the instructions supplied with the tool. Most often, the recommended remedies are indicated there;
- Purchase grease from any trusted and reputable manufacturer.
Rotary hammer lubricant. Sincere concern for the instrument!
Modern rock drills, depending on the class, can be used for drilling, drilling and chiselling even in such hard materials as concrete. All of the above modes, except for increased noise, during work lead to the release of a large amount of dust, small stone chips, etc.
These extreme conditions necessitate frequent cleaning and lubrication of the device. Typically, two types of lubricant are recommended for operation: grease for the hammer drill gearbox and for drill bits, drills and other replaceable work bits. In this case, a thinner oil is used to lubricate the gearbox.
For most models, the instructions for use indicate the timing and frequency of oil changes. Accordingly, there are special hatches and openings for filling oils in the body of the perforators, which are closed with sealed covers or screws.
As a rule, there are problems with the choice of the type of oil for quality rock drills from well-known manufacturers. The instructions indicate recommendations on which oil to pour into the perforator, in what quantity. But what if there is no such data? Diesel engine oil can be recommended.
Along with this, the instrument heats up more. In order for the oil for the hammer drill again to enter the indicated zones, it is necessary periodically (once every 20 minutes) to switch to the drilling mode, thereby providing not only lubrication of the rubbing parts, but also their cooling. It is obvious that such mode changes will have a beneficial effect on the long-term performance of the rock drill.
Knowing how to lubricate the hammer drill gearbox, however, it is important to do it at regular intervals. How often do you need to change the oil, what should be guided by and how to determine when the replacement is due? Experts recommend doing this with an eye on the instructions, but be guided by the practical side and, first of all, by the intensity of using the tool, the magnitude of the loads during the performance of work, the conditions of their conduct (including dustiness).
Preventive replacement is recommended after changing the motor brushes. Although an experienced master of sound and increased rigidity of the instrument can determine the need for an oil change.
Before lubricating the hammer drill, it is necessary to clarify whether the warranty period has expired. Because not all models have access to the gearbox housing in the form of a hatch or hole. And in this case, disassembly of the case may be required. It is better to entrust it to the specialists of the service center. over, if the instrument is still under warranty.
When self-lubricating the gearbox, you must first remove the old one. For this, the crankcase is flushed with kerosene, diesel fuel or liquid engine oil ( spindle). If you have to disassemble the case, the mechanism can be pre-purged to remove accumulated dust and dirt. Remember that you blew and flush the mechanisms, you should lubricate everything that previously had lubrication (for example, a helical gear), and that that did not have it, in no case should you lubricate (for example, a transfer clutch).
The approximate procedure includes preparing lubricants. As the latter, it is recommended to use greases from the manufacturer of the rock drill, despite their higher cost. Perhaps, in the absence of a proprietary, the most versatile lubricant for a hammer drill. This is the famous lithol.
For drill shanks and other replaceable nozzles, experts unanimously recommend covering them with a small amount (no more than a pea) of lubricant, for example, lithol or grease. This must be done every time before installing in the chuck.
After removing the nozzle, the shank must be cleaned from accumulated dust. By the way, the choice of lubricant, especially for shanks, must be done with care, avoiding oils that can cause adhesion due to heating of the nozzle and jamming of the impact mechanism.
