will probably bend and cause personal injury if it is allowed to rotate freely without contact with the workpiece.
Apply pressure only in the direction of the drill axis. Do not apply excessive pressure. The drill can bend, causing breakage
or loss of control which will result in personal 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 auxiliary handle (II)
Affi x the clamp of drill chuck to drill body, select the chuck position in such a way as to ensure the safest work. The position of
chuck should be selected in such a way, that it could be possible to fully counteract the torque directed opposite to direction of
rotation of drill chuck. This torque is generated during normal operation, but the highest value is reached when the drill is chocked
in the processed material. Secure the chuck position by tightening the grip handle of auxiliary chuck fi rmly and reliably.
Installation of drilling depth limiter (III)
Put the limiter bar through the hole in the grip handle of auxiliary chuck. The position of limiter must be secured depending on the
type of installation: by tightening the grip handle of the auxiliary chuck, by tightening the knob individually or by means of the lock
knob. Detailed method of locking the position of limiter is shown in the illustration.
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 roller grip proper for specifi c job. Insert the drill bit into the chuck and then holding the back of the chuck rotate
the front part of the chuck, so that the drill is fi xed in the chuck tightly and reliably.
Adjustments of rotation (V)
Drill is fi tted with smooth rotation control. Control is carried out by means of a knob placed on the switch. Rotation mark in form
of an arrow, „+" and „-" symbols, or similar symbols, informs to which side the know should be turned to increase or decrease the
rotational speed. Rotation of the knob adjusts the range of switch movement, which translates into the value of maximum speed.
Gradually pressing the switch we accelerate the rotation of motor.
Warning! Drill was fi tted with mechanical rotational speed control by means of changing gear ratio. Setting the switch in a fi xed
position allows selecting one of the speed ranges specifi ed in the table containing technical data.
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 fi xed, 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 fi nger.
