Adjustment of the direction of rotation
Place the selector of rotation to R – right rotation or L – left rotation (VI).
Attention! The direction of rotation may be changed only if the power supply is off! It is prohibited to change the direction of rota-
tion during operation of the drill and screwer!
Installation of screwdriver bits in the drill chuck
Place a bit holder in the drill chuck and install an adequate bit. (VII)
Preparation for work
Before work:
Secure the material to be processed in an anvil or using woodwork clamps.
Use tools which are adequate for the job to be done. Make sure they are sharp and in good conditions.
Wear protective clothes as well as eye and hearing protectors.
Hold the tool with both hands (VIII).
Adopt a stable and secure position.
Turn the tool on pressing the switch with a finger.
Attention! In case suspicious noise, cracks and smell are detected during operation, the tool must be immediately turned off and
the battery removed.
USING OF THE TOOL
Attention! Use hearing protection while using the tool!
Using right or left rotation
The right rotation should be used while drilling with common dextrorotatory drill bits.
The left rotation should be used if the dextrorotatory drill bit is seized in the material and to remove bolts. In case of removing
bolts, use the lowest rotation.
Drilling in wood
Before making a hole it is recommended to secure the material with clamps or in an anvil, and then to mark the point to be drilled
with a centre punch or a nail. Secure an adequate drill bit in the drill chuck, adjust the torque, connect the tool to the battery and
start drilling.
In case of making holes through the material, it is recommended to place a wooden pad under the material, so as to avoid fraying
of the edge of the hole.
In case of making holes of large diameters it is recommended to drill first a smaller guiding hole.
Drilling in metals
Always secure the material to be processed. In case of thin sheet it is recommended to place it on a wooden pad so as to avoid
undesired bends, etc. Then mark the points to be drilled with a centre punch and start drilling.
Use drill bits for steel. In case drilling is done in white cast iron, it is recommended to use sintered carbide drill bits.
In case of making holes of large diameters it is recommended to drill first a smaller guiding hole.
In case of drilling in steel, cool the drill bit with machine oil.
In case of drilling in aluminium, cool the drill bit with turpentine or paraffin.
In case of drilling in brass, copper or cast iron, do not use cooling agents. In order to cool the drill bit, it should be often removed
from the material.
Drilling in ceramic materials
Drilling in hard, compact materials (concrete, hard bricks, stone, marble, etc.)
Applies only to hammer tools.
Before the desired hole is made, drill a smaller hole with the hammer function off. Drill the proper hole with the hammer function
on. Use hammer sintered carbide drill bits in good conditions.
Drilling in glaze, soft bricks, plaster, etc.
Use hammer drill bits. Do not turn the hammer function on (if applicable). During drilling press the tool hard with constant force.
Remove the drill bit from the hole being drilled from time to time, in order to remove dust and waste.
Using the tool to screw bolts in and out
It is recommended to use the lowest rotation and adequate bits.
Bits may be installed directly in the drill chuck or with a special magnetic holder.
In order to unscrew a bolt select the left rotation (L).
Using attachments
The tool must not be used to power working attachments.
