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 installation and replacement of the working tools, 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 drills in the chuck (IV)
Select a drill with a cylindrical tang which is appropriate for the task to be realised.
Install a drill in the chuck and tighten it with the key in each of the three holes so that it is installed in a tight and safe manner. Then
remove the key from the hole.
Adjustments of rotation (V)
The hammer drill permits continuous adjustments of rotation. Adjustment is possible by changing the position of the handwheel
next to the switch.
Setting the direction of the rotation (VI)
Set the rotation switch in accordance with the arrows; right rotation – the arrow pointing to the front of the tool, left rotation – the
arrow pointing to the back of the tool.
Attention! The direction of the rotation of the tool may be changed only if the power supply voltage is off!
Activation of the hammer function (VII)
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 hammer.
While drilling in other materials, the hammer action function must be deactivated, setting the selector to the drill symbol.
Preparation for work
Before work:
The processed material must be appropriately fixed, using an anvil or clamps.
Use tools which are appropriate for the task to be realised. Make sure they are sharpened and in good conditions.
Wear working clothes and sight and hearing protection.
Plug the cord to the mains.
Hold the drill with both hands by the handle and the additional handle
Adapt a position that guarantees equilibrium.
Turn the hammer drill off, pressing the switch with a finger.
Attention! In case any suspicious sounds or smell are detected the hammer drill must be immediately disconnected from the
mains.
OPERATION OF THE TOOL
Right or left rotation
Right rotation should be used while drilling with common right turn drill. Left rotation must be used if the right turn drill is jammed
in the material and in case of driving screws.
In case of driving screws into a surface, minimum rotation must be used.
Using the switch lock
It is recommended to use the switch lock in case of long drilling, e.g. in case of drilling in concrete, walls, etc. While the switch
is pressed, press the lock button with your thumb and release the switch. In order to release the lock, it is sufficient to press the
electric switch.
Drilling in wood
Before drilling, it is recommended to fix the material to be processed with a clamp or in an anvil, and then using a punch or a nail
mark the place of drilling. Install the drill in the chuck, set the speed, connect the drill to the mains and start drilling.
In case of drilling through the material, it is recommended to place a wooden pad under the material, so that the edge of the hole
at the outlet will be smooth.
In case of drilling large diameter holes, it is recommended to drill first a smaller guide hole.
