Do I Need to Lubricate the Hammer Drill

Each tool needs timely maintenance, and the punch is required in the first place. After all, the work of this tool is accompanied by a huge number of reciprocating rotations and movements, and the amount of dust emitted from the working object has a large concentration. Under these operating conditions, careful care of the device and timely replacement of grease in the perforator gearbox is required.

Most users are confident that if grease is present, then you can work with it an indefinite amount of time. This opinion usually exists among users due to a poor level of knowledge of the laws of physics, therefore, we will talk about the mechanism of lubrication in more detail.

What is punch lubricant and why is it needed?

Lubrication is a viscous substance designed to minimize the coefficient of friction between parts of a tool. Reduce, not completely remove. That is, it means that friction between parts is almost always, and part of the small particles are separated from the tool and into the oil itself. After a while, this grease saturated with metal dust no longer fulfills its immediate function. At first, its viscosity simply changes, and later, the grease itself is the reason for the rapid wear of tool parts. Viscosity is considered the main parameter that you need to pay attention to when buying it.

The manufacturer without fail indicates in the technical documentation all the characteristics of the tool and the lubricating mass that must be used. Much attention should be paid to the frequency of maintenance, where it is indicated after what time it is necessary to replace the lubricant.

For a hammer drill, which has a quality certificate, you need always use only proprietary lubricants, otherwise, after the failure of the instrument, you will lose the right to warranty service. After the warranty period, it is also better to use the lubricant recommended by the manufacturer, but at this time, most often, the user uses cheaper domestic counterparts. Litol or solidol will not harm your instrument in any way. But do not forget that lithol is produced much faster, that is, its replacement must be done much more often.

What is needed to lubricate the punch gearbox?

This lubrication is also required for the temperature regime of operation. But this does not mean at all that it is impossible to use lithol. There are factors when, when using a domestic lubricating fluid, the impact force of the tool only increases and the noise level created by it decreases. This is even more true for a Chinese-made punch.

Users of the Chinese tool do not hope for warranty service, therefore, they act at the personal discretion from the very beginning of the operation of the drill (or electric drill). Because a punch of any manufacturer has its own fundamental design features, then there is simply no single lubrication instruction. The main thing that you have on hand:

  • rags;
  • instruction manual punch;
  • branded grease or its domestic counterpart.

And then, as you already understood, we act clearly according to the instructions. And remember that anyway the hammer must be cleaned as much as possible from dust after work. Make sure that the lubrication level is no more than the reference mark. Most often, the perforator has a special container for the lubricant, that is, to make this whole procedure will not be very difficult.

It is undesirable to lubricate the gearbox in the punch right after work, because hot parts when they get cold lubricant lose their physical characteristics. The drill shank also needs to be greased with lithol or solid oil. If the hammer has an open cartridge, then it is advisable to process the oil seal. First, it must be disassembled and wiped thoroughly. The applied grease will make it possible to extend the life of the device and will protect it from dust entering the instrument. There are several types of lubricating compounds:

  • for gearbox;
  • for drill tips;
  • for drills.

Is it possible to disassemble the hammer drill gear yourself?

Great attention to themselves requires a gear reducer. Lubricating parts of the gearbox is not so difficult, but before the expiration of the warranty period, it is undesirable to lubricate the punch. You can disassemble the gearbox in any case, but not everyone can assemble it. With gear lubrication problem it is advisable to contact the company service center or specialized workshops. This is a rather delicate work, therefore it is advisable to entrust it to professionals. But there are times when this nearest center is far from you, so you need to do the gearbox lubrication yourself.

Pay attention to all parts during disassembly. Some of them have absolutely no lubrication. This does not mean that the grease on them has already been used up. Just some of the parts of the gearbox is not processed. You also do not need to lubricate them. During disassembly, we try to remember as much as possible the location of the parts and the order in which they are disassembled. Thus, you will not have "extra" spare parts during assembly. All parts of the gearbox need rinse thoroughly with gasoline (or spindle) and wipe dry with a rag. Rinse and gear housing inside. You should not rush with the assembly: let the body dry well.

Why does the hammer drill overheat?

And now we do lubrication of all parts of the gearbox and assemble it in the reverse order. Do not forget that an excessive amount can also affect the performance of the tool: it may significantly increase the heating of the gearbox.

If the punch during operation began to heat more than usual, then this does not mean that there is a problem with lubrication. Most likely, you used the chiselling mode for a very long time and the lubrication simply did not pass to all parts of the punch in the right amount.

Another reason may be clogged holes for cooling the motor. In this case, the solution is one: to clean the tool from dust and transfer it temporarily to a different operating mode. If the puncher will work for half an hour like a regular electric drill, then the temperature of the case will significantly decrease. Gearbox required to have the same temperature in any mode operation of the punch.

Features of maintenance of electric drill with punch function

The electric drill, which works with the function of a hammer drill, is much more difficult to maintain. This hybrid tool has some disadvantages, unlike a conventional hammer drill:

  • they do not have special containers for filling the lubricant;
  • it’s much more difficult to maintain a drill chuck.

Permanent lubrication is only required for the drill tip. The amount of lubrication is minimal: just clean the drill from dust and apply a small amount of solid oil (the size of a match head) to the tip. The same requirements apply to the lubrication of a drill of a conventional hammer drill. An excess amount of lubricant on the storm will not harm the tool mechanism, but in any case, it will splatter and may cause damage to the repair of the room. But if the grease is brought into the gearbox in excess, then it simply spills out.

I need to say a little about professional rotary hammers. In the home use of this tool, as a rule, does not happen. Here, first of all, the price of the instrument plays its role, and therefore they choose it much less often. But at the same time this tool is considered the simplest and unpretentious in operation. There is usually no problem with the lubrication of this tool, because the design of the mechanism is very simple.

The gearbox also does not have any features that make it difficult to maintain. Everything is simple: we unscrew the drain valve, pour the spent grease into the tank, rinse the perforator grease tank, twist the drain hole and pour new grease to the desired mark. The gearbox of this rotary hammer is serviced exactly as described above.

How to choose the lubricant for the punch?

One of the most popular means is diesel engine oil. Also graphite grease is pretty good, it is often used for open worm gears. Litol 24 is also popular, but this lubricant also causes braking and additional heating. Yes, and it works for a relatively short time, unlike branded grease for a rotary hammer and for cordless tools it is extremely undesirable.

How to lubricate a hammer drill and what is needed for this?

As a rule, many users have a question. how often and what needs to be lubricated in a punch? Since the intensity of operation for all devices is different. Some work with a rotary hammer once a year, and some all the time use it for different jobs. Experts recommend looking at the number of loads, as well as the recommendations in the technical passport. In this case, it is imperative to consider whether the punch has passed the warranty service time.

The next question that arises among users is how to lubricate a punch with your own hands? For example, the warranty period is over or you just decided to do all the work at home. Modern rotary hammers have a special compartment, into which oil is poured. Most often, the instructions indicate where this hole is located. Also, a disassembly diagram should be indicated here. The quantity of oil that is required is poured into the hole (this is prescribed in the instructions). But before doing this, it is necessary to rinse the crankcase with engine oil or gasoline. If there is no special hole and the hammer must be disassembled, then you can blow it along the way.

Only after flushing and flushing can lubrication begin. Do not lubricate the transmission clutch and other areas that do not require lubrication. In addition to the gearbox, if necessary, drill and other interchangeable nozzles can be greased. Suitable for this purpose "Litol." If the tool has an open cartridge, then it is possible to treat with grease and oil seal. But you need to apply a small amount of oil to these places. it it is advisable to perform before each installation nozzles, After removing it, be sure to wipe the shank away from dust.
