Unmodified plugs and matching sockets will reduce risk of electric shock. Take the necessary precautions against electric shock. Avoid contact of the tool case with grounded surfaces such as pipes, heating, and refrigerators. Protect the power tool from rain and dampness. The water ingress into the power tool increases the risk of electric shock. Do not use the cable for other purposes, for example, for transportation or hang of the power or to pull the plug from the socket. Protect the cable from high temperatures, oil, sharp edges or moving parts of the power tool. Damaged or entangled cords increase the risk of electric shock. When working outdoors, use an appropriate power extender. Only use a power extender that is suitable for outdoor works. If you cannot avoid using the power tool in a damp location, install protection switch of the short circuit currents. The use of protection switch of the short circuit currents reduces the risk of electric shock.

3. Personal safety:
   Be careful, keep an eye on what you are doing, and carefully start operation with the power tool. Do not use the power tool when you are tired or when you are under the influence of drugs, alcohol or medication. One moment of inattention while operating power tools may cause the serious personal injury. Use personal protective equipment and always goggles. The use of personal protective equipment: a protective mask, shoes with non-slip soles, a protective helmet or hearing protection depending on the type of power tool operation reduces the risk of injury. Prevent unintended activation of the power tool. Before connecting t he power tool to the power supply and/or to the battery, make sure that the power tool is turned off. Do not hold the connected tool by the switch. Remove the installation tool or wrenches before turning on the power tool. A tool or wrench located in the rotating part of the power tool may cause injury. Do not assnme an unnatural body position. Always take a stable position and always keep balance. Thanks to this you can better control the power tool in unexpected situations. Wear suitable work clothing. Do not wear loose clothes or apparels. Keep hair, clothing, and mittens away from moving parts. Wide clothes, apparels or long hair can be tightened by rotating parts. If it is possible to install dust extraction and dust collection devices, check their connection and correct use. The use of a dust extraction can reduce the dangers created by dust.

Take into account the working conditions and the work performed. The use of power tools for unintended work can lead to dangerous situations. The unused tool should be stored in a dry, closed place, not accessible to children! Do not allow persons who have not read this operation manual to use the tool.

EXPLANATION OF P.I.T. TRADEMARK
P.I.T. Progressive Innovational Technology Currently, 10 kinds of mechanical and electrical equipment are produced under the P.I.T. trademark. In terms of sales, Rotary hammers occupy one of the leading positions. Each letter and number in the designation of the model of P.I.T. rotary hammers has the meaning.
For example, PBH26-C
P-Trademark of P.I. T.
BB -rotary hammer 26

• maximum diameter of the borer
• modification series

INTENDED USE
Rotary hammer is designed for drilling bores in concrete, brick and natural stone (the function of rotating and percussive drilling), as well as for light grooving work (impact function). It is also suitable for drilling bores in wood, metal, ceramics and synthetic materials (rotary drilling function). Rotary hammers with electronic control and reverse direction of rotation are also suitable for securing screws.

PRINCIPLE OF OPERATION
The servo mechanism transmits the movement to the piston, which inside the air cylinder makes a reciprocating motion, creating pressurized air. The pressure of the pressurized air inside the cylinder transmits the movement to the upper part of the hammer, performing reciprocating movements, strikes are made, the same as we apply a conventional hammer. Due to the presence of a pneumatic mechanism, the impact force of the rotary hammer is much higher than that of a hammer drill. The principle of operation of the rotary hammer is divided into two stages:

Impact stage:
The rotating electromotor of the rotary hammer transmits the movement to the crank-type piston-rod, causing the piston to make reciprocating movements, when pressurized inside the air cylinder, a hammer blow is made, which is transmitted to the shank of the rotating head, thus, the process of hitting the hammer is considered complete.

The rotation stage:
The gear of the rotating cylinder gives movement to the rotating head. There is a simultaneous rotation with the collision.

RULES OF OPERATION

Installing an additional handle
In order to \Ulscrew the fixation ring of the additional handle, it is necessary to rotate the handle co\Ulter-clockwise while holding the upper part. After that, the handle is placed on the perforator and fixed, rotating its handle clockwise. To hold the perforator in any position during drilling, the side handle can be mo\Ulted on the perforator in any position.

Setting the drilling depth delimiter
Used for drilling holes of the equal depth. Loosen the additional handle, and insert the depth delimiter into the hole, set the desired drilling depth and tighten the handle. Replace of borers

ATTENTION! Before starting to replace the borer, you must disconnect the electric cable from the socket. When changing the borers, be careful, since it is possible to damage the dust guard of the chuck. The SOS-Plus chuck automatically locks the borer during installation.

However, during installation, slowly turn the borer in the chuck lllltil it locks into place. After installation, make sure that the borer is securely fastened, trying to pull it out of the holder. Note that when the tool is running without load, the borer has a slight backlash, but this does not affect the boring accuracy, because when the slightest load occurs,
the borer is automatically centered. To remove the borer, it is necessary to slightly pull back the chuck. To work with the perforator was most effective, periodically check the sharpening of the borers and sharpen them if necessary, and lubricate the borer liners with special grease before use. For work with metal, wood, plastic, a chuck with a ring gear is used. The chuck is installed using a special adapter SOS-Plus. To perform operations with fasteners, you need to use the bits and special adapter SOS-Plus.

ATTENTION!
The chuck, bits and adapters may not be included in your tool kit. These and other accessories can be purchased at a specialized store or an authorized technical service center.

Replace of dust guard of the chuck
In case of damage of dust guard of the chuck, replace it, since dust entering the chuck may cause to the failure of the tool. To replace the dust guard, it is necessary to take back the chuck and remove the dust guard, then install a new one.

Setting the rotational direction
Using the switch, you can set the rotational direction of the shaft clockwise or co\Ulter-clockwise. This function allows you to use this tool as a screwdriver to work with fasteners, as well as to extract the borer when jammed.

ATTENTION!
Do not set the rotational direction switch to the anti-clockwise rotation position when using the drill with impact or grooving function. For safety reasons, when the rotary shaft rotates CO\Ulterclockwise, the switch cannot be fixed with the button. Before starting operation, check the correct rotation direction. Only switch the reverse when the engine is completely stopped. Changing the rotation direction on a machine with a rotating shaft will result in damage to the machine. Do not press the start switch if the direction switch is in the neutral position. Do not apply force when reversing.
