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 suffi cient to press the
electric switch.
Drilling in wood
Before drilling, it is recommended to fi x 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 fi rst a smaller guide hole.
Drilling in metals
It is always necessary to fi x the material to be processed securely. In case of thin sheet metal, it is recommended to place a piece
of wood under it, so as to avoid any deformations. Then mark the places of drilling using a punch and start drilling. Use drills for
steel. In case of drilling in white cast iron, it is recommended to use drills with sintered carbide bits. While drilling larger holes, it is
recommended to drill fi rst a smaller guide hole. While drilling steel, cool the drill with machine oil. In case of drilling in aluminium,
use turpentine oil or paraffi n to cool the drill. In case of drilling in brass, copper or cast iron do not use any substances to cool the
drill. In order to cool it, is required to remove it frequently from the material.
Drilling in ceramic materials
Drilling in hard and compact materials: concrete, hard bricks, stone, marble etc.)
Before drilling the proper hole, it is recommended to drill fi rst a smaller guide hole with the hammer function off . The proper hole
should be drilled with the hammer function on. Use drills with sintered carbide bits in good conditions.
Drilling in glaze, soft brick, plaster, etc.
Drill as described in the point above, but without hammer action.
From time to time remove the drill from the hole, in order to remove dust and debris. While drilling press the tool hard with constant
strength.
Using the drill to drive or remove screws
A drill with adjustable rotation and a switch to change the direction of rotation may also be used to drive screws in and remove
them. In order to do so, the following is recommended:
- use the lowest rotational speed,
- use appropriate bits.
Bits may be installed directly in the chuck, or with a special magnetic holder.
In order to remove a screw set the direction of rotation to the left (L).
Carving holes
The drill may be used to carve larger holes in wood, using special drills of fi xed diameter or interchangeable bits from the saw set
– jig-saws. In order to obtain smooth edges of the outlet of the hole, place a piece of wood under the material.
Using attachments
Drills with adjustable direction of rotation should not be used with attachments.
Drilling with the depth delimiter (VIII)
The delimiter can be used to facilitate the drilling of surfaces, where there are performed blind holes, particularly in concrete and
wood. Determine the depth of the hole. Install the drill bit in the holder, by using a pen you should mark on the drill bit a distance,
from the working drill end which is equal to the depth of the hole. set the depth delimiter so its end would cover the marked the
distance „L" on the bit. Make sure, that the delimiter does not move during operation. Start drilling, at a fi xed depth the delimiter
forehead will rest on the surface around the hole. You should withdraw the drill bit out of the hole.
