Rotary hammer equipment
To work with this tool, you need a variety of equipment. drills, drills for concrete for hammer drills, chisels, blades and crowns. Drills and crowns are used when drilling holes, drills are used for concrete and stone, chisels are used for slotting work, and blades are needed to knock down plaster or old tiles. All rock drill bits are shaped like a shank, thanks to which a quick and reliable fixation in the chuck is carried out.

Before starting any work with the rotary hammer, make sure that it is properly equipped and suitable for the future work. A tool that is too small may not handle a heavy load.
Purchase of the chuck
You need to purchase a special chuck that fits your hammer drill model. If you cannot choose or do not know which cartridge is needed, it is best to take the tool with you and try compatibility on the spot.
Today rock drills are equipped with two types of cartridges. quick-clamping and key. The key option is the traditional one, a wood drill for a perforator is clamped in it using a special key. In this case, the fastening is reliable, but less convenient than that of a keyless chuck. The keyless chuck easily grips the drill without the need for any tools. Just choose the one that suits you best and follow the further instructions.

For this, insert the plug into the outlet, and put the punch in the drilling mode without a fight (left extreme position). After that, the start button is pressed.

Inserting the chuck
For proper operation of the tool, it is necessary to lubricate the hammer drill with special grease. It is better to purchase a proprietary product that is resistant to water and prevents moisture from entering metal surfaces, which prevents corrosion.
To do this, you need to open the tube of grease and squeeze a little into the hole into which the nozzles are inserted. Next, the tool is placed on the floor or on another hard, comfortable surface with a handle, after which the back of the hammer head is pulled down, the chuck is inserted, and the lower part of the head returns to its previous position.
Choosing a drill for a hammer drill
Today drills are made from carbon steel, high speed steel and alloy steel. If you have to work with tough materials, the drill can be equipped with heavy duty tough soldering. Drills are nib, centering, with straight flutes and spiral (for deep drilling).
You can also purchase a drill designed for wood, metal, stone, concrete, glass, ceramics, diamond, or a universal version. Before you fix the drill in the hammer drill, you need to decide on the type if you want the work to be done correctly. The color of the drill indicates the appearance of the final result.
If the drill is colored black, it means that it was processed with superheated steam, but this does not affect the quality, despite the popular belief that black drills are stronger. If the drill has a brown or slightly golden hue, it is most likely stress relieved. Drills that are treated with titanium nitrile have a bright gold color, such options are the most expensive and durable.
As a rule, good companies indicate on the drill boxes its characteristics, such as the steel grade and the material that can be worked with. If the drill gets very hot during operation, it means that it is dull or was sharpened incorrectly.
Beginning of work
Before starting work, you need to make sure which mode the tool is in. It should be idling for one minute. Be sure to check the operation of the gearbox so that vibrations, unnecessary noises or sounds do not come from it. Also, there should be no smoke or smell resembling burning insulation.
For drilling, you need to install the drill in the place where the hole will be made and only then press the power button. When working with a hammer drill, do not press too hard on the surface. Modern rock drills have an on / off feature. This property of the tool is able to provide the main work with a decrease in speed. Thanks to this mode, the hole will be made in a precisely defined place and the drill will not go to the side.
When drilling metal or wood, do not turn on the hammer mode, this may damage the device. There are rock drills that have an automatic shutdown mechanism when the wrong option is selected. During construction work, the impact mode can be used for drilling concrete. To free the hole from dust, it is necessary to periodically remove part of the drill and return it to its place.
After the above steps, you can insert the Makita Rotary Hammer Drill into the chuck. Then, by rotating the upper part of the chuck clockwise until it stops, it is necessary to clamp the drill. After that, be sure to check if it is firmly fixed.
If you find the drill is loose, try tightening the chuck a little more. After the final fixing and following all the actions, you can turn on the puncher in the network. Press the trigger several times so that the grease can disperse well into the parts.
