ADDITIONAL SAFETY INSTRUCTIONS
Use hearing protectors. Exposure to noise can cause hearing loss.
Use the tool with the additional handles provided. Loss of control can cause personal injury to the operator.
Hold the power tool by the insulated handles to avoid the risk when the drill bit attached comes into contact with a live,
concealed cable or power conductor when working. When the bit is in contact with a live wire it may cause the metal parts of
the tool to become live, which may give the user an electric shock.
Safety warnings for drilling with long bits
Always start drilling at low speed and make sure the end of the drill bit is in contact with the workpiece. At higher speeds,
the drill might bend and cause injury if it is allowed to rotate freely without contact with the workpiece.
Apply pressure only in a straight line with the drill and do not press too hard. The drill can bend, causing breakage and loss
of control which will result in injury.
EQUIPMENT INSTALLATION
CAUTION! Only install the equipment when the supply voltage is disconnected. Pull the tool power cord plug out of the mains
socket!
Installing the additional handle (III)
Put the additional handle clamp on the tool body and after setting the handle in the most ergonomic position for the job, fi x it by
tightening the handle.
Installing the drilling depth stop (IV)
Loosen the additional handle fasteners. Slide the straight part of the drill depth stop into the hole in the additional handle and
tighten the additional handle again after adjusting the correct position. The bent part of the stop should be as close as possible to
the drill bit. As the drill bit is driven into the hole, the stop will rest against the drilled surface to achieve the intended drilling depth.
Due to design of the tool, the full range of stop lengths may not be available in all positions of the auxiliary handle.
PREPARING FOR WORK
Before starting work, make sure that the housing and the connecting cable with a plug are not damaged. Stop working in case
of damage!
Caution! All activities related to changing tools (drills and chisels with the SDS MAX Plus attachment), installing covers and guides,
adjusting, etc. should be done with the tool disconnected from mains. For this reason, before proceeding: Pull the tool power
cord plug out of the mains socket!
Inserting the SDS Plus work tools into the tool holder
Clean the selected tool from dirt and rust and lubricate the SDS Plus holder with a thin layer of grease.
Pull the tool chuck ring towards you and hold it in this position (V).
Insert the cleaned tool into the hole. If necessary, rotate the tool to make sure it fi ts in the chuck without any resistance.
Release the chuck ring. The tool should automatically lock inside the chuck.
Make sure the tool has been seated fi rmly. To do this, simply try pulling the tool out of the SDS-Plus chuck. Repeat all installation
steps, if the drill or chisel comes out of the chuck.
Setting the operating mode (VI)
The tool is equipped with two work mode selector switches. The drilling mode selector located near the switch and the impact type
selector located on the side of the body.
Set the drilling type selector so that its wing indicates one of the following symbols: drill – drilling without impact; drill and hammer
– drilling with impact.
Set the impact selector so that the indicator on the tool housing indicates one of the symbols on the switch: drill and hammer –
impact drilling; hammer – chiselling; chisel and arrow – chiselling position. Changing the position of the switch is done by pressing
and holding the button lock, and then turning the switch.
During hammer drilling, in addition to the rotational movement, the drill bit simultaneously makes a reciprocating movement back
and forth so that its tip strikes the material being drilled. Such drilling requires bits with a blade made of sintered carbide and allows
making holes in concrete, masonry and hard ceramic materials (hard bricks, stones, marble).
For chiselling the rotational movement is stopped, but the reciprocating movement is maintained. Chiselling requires the use of a
chisel or punch with a shape appropriate to the surface being worked and material type.
The position of the chisel must be set by rotating it manually. After setting the position, move the impact mode switch to the
chiselling position.
