resulting in injury.
INSTALLATION OF THE ACCESSORIES
ATTENTION! Installation of the accessories must be carried out when the power supply voltage is disconnected. Remove the plug
of the cord of the tool from the mains socket!
Installation of the additional handle (III)
Install the additional handle in the desired position and tighten it, turning the grip of the handle.
PREPARATION FOR WORK
Before work may commence, it is necessary to make sure the enclosure and the cord with plug are not damaged. In case any
damage is detected, it is prohibited to continue working!
Attention! All actions consisting in replacement of the working tools (drill and cutter with the SDS Plus chuck system), installation
of guards and guides, adjustments etc. must be carried out when the power supply voltage is disconnected: Remove the plug of
the cord of the tool from the mains socket!
Installation of SDS Plus working tools in the tool chuck
Clean the selected tool of dirt and rust and lubricate The SDS Plus chuck with a thin layer of grease.
Tool the tool chuck towards you and maintain it in this position (V).
Insert a clean tool in the opening. If necessary, turn the tool, so that it enters the chuck without resistance.
Release the chuck; the tool should lock automatically in the chuck.
Make sure the tool is securely installed, trying to remove it from the SDS-Plus chuck. If the drill or the cutter can be removed from
the chuck, the installation procedure must be repeated.
Selection of kind of operation (VI)
The hammer action operation facilitates drilling in concrete, walls and hard ceramic materials (hard bricks, stones, marble). The
hammer action selector must be set to hammer action indicated with a symbol of a drill and a hammer.
It is also possible to set the hammering function. In this mode rotation is stopped, but the hammer action is still on.
In order to do so, set the operating mode selector to the hammer symbol.
Preparation
Select adequate tools and install them in the chuck.
Set the operating mode selector to the adequate position: hammer symbol – hammering; hammer and drill symbol – drilling with ham-
mer action; drill symbol – drilling without hammer action; hammer with an arrow – setting the position of the position of the chisel.
Wear hearing and eyes protection, and protective gloves.
Plug the cord to the mains.
Adapt a position that guarantees equilibrium, grab the hammer drill with both hands and start it pressing the electric switch (VIII).
Hold the tool for a couple of minutes, so that the lubricant reaches all the elements of the drive mechanism.
Turn the hammer drill off , releasing the switch.
Attention! In case any suspicious sounds are detected the hammer drill must be immediately disconnected from the mains. Have
it inspected by an authorised service point.
USING THE TOOL
Attention! While operating the hammer drill, it is required to use hearing protection!
Drilling in ceramic materials
Drilling in hard and compact materials: concrete, hard bricks, stone, marble etc.
While the hammer drill is disconnected from the mains, install a drill in the chuck.
If necessary, install the drilling depth-limiting device.
Set the operating mode selector to drilling with hammer action, or if it is available, to drilling without hammer action.
Plug the tool to the mains, turn the hammer drill on with the switch and start work.
During work make regular breaks – avoid overheating of the hammer drill and the tool.
Drilling with hammer action is recommended only in case of compact ceramic materials: concrete, hard bricks, stone etc. In case
of drilling holes of large diameter, it is recommended to drill fi rst a smaller guide hole, and then use a drill of the fi nal diameter. Use
drills designed for hammer action drilling.
It is not recommended to use the hammer action function in case of ceramic materials of loose structure, such as: glaze, soft
bricks, plaster, etc. Hammer action drilling in such materials may damage the material.
