adjust the ring on hammer symbol this will start the hammer mechanism. Drilling with stroke should be used for drilling in concrete,
and it should not be used for drilling in wood or plastic.
In the case when you use of the tool for drilling holes, you should adjust the ring to the symbol of a drill or a hammer, This will
disconnect the overload clutch, and the maximum torque will be transferred to the drill bit.
Attention! You should not use the settings which are marked with numbers for drilling. Operation of the overload clutch during
drilling may cause the destruction of material or damage the drill bit, this would also increase the risk of injury.
Mounting the drill bits in the self-locking chuck
You should select the drill which is appropriate for your work with roll drill bit chuck.
Insert the drill bit to the chuck. Hand tighten the chuck, till the drill bit will be fi rm fi xed (V).
Set the maximum torque. The torque knob you should set to the symbol of a drill or hammer.
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 fi nger.
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 fi rst 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 fi rst 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 paraffi n.
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 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.
