OPERATING
Never cover the air vents since they must always be
open for proper motor cooling.
DRILLING IN WOOD
To prevent ugly splits around the drill hole on the reverse
side of the workpiece, put a piece of scrap timber under
the work piece.
DRILLING IN METAL
Metals such as steel, brass, aluminum sheets, stainless
steel, and pipe may also be drilled. Mark the point to be
drilled with a nail or punch.
Do not use impact drilling mode on these materials.
DRILLING IN CONCRETE
Stone and masonry are generally drilled in the impact
drilling mode.
When drilling in delicate materials such as wall tiles, it is
essential to start with ordinary drilling and, once the tile is
pierced, to continue with impact drilling.
In deep bore holes the drill bit should be pulled out
occasionally in order to remove the debris from the drill
and hole.
AUXILIARY HANDLE AND DEPTH GAUGE
See Figure 6.
Auxiliary handle
The auxiliary handle can be rotated 360º.
Loosen the handle grip by turning in direction, and tighten
it at an easy to use position by turning the grip in direction.
Depth gauge
Holes of a fi xed depth can be accurately bored by using
the depth gauge.
The depth of the hole will be the distance from the end of
the bit to the end of the depth gauge.
By turning the handle grip in direction, the depth gauge
can be released and the depth adjusted. After adjusting
the depth, fi x the depth gauge again by turning the handle
grip in direction.
