DWT BM04-10 Notice Originale page 23

Changing the rotational directions
Change the direction of rotation only
after a full stop of the motor, acting oth-
erwise may cause damage to the power
tool.
Rotation to the right (drilling, screwing in) - move
the rotational direction switch 4 to the right�
Rotation to the left (unscrewing) - move the rota-
tional direction switch 4 to the left�
Recommendations
on the power tool operation
Drilling (see fig. 8-11)
• Grease the drill bit regularly when drilling holes in met-
als (except drilling non-ferrous metals and their alloys)�
• When drilling hard metals, apply more force to the
power tool and lower the rotation speed�
• When drilling large diameter holes in metal, first drill
a hole with a smaller diameter and ream it till the nec-
essary diameter (see fig. 8).
• In order to avoid splitting of the surface at an exit
point of a drill bit when drilling holes in wood, follow the
instructions shown in figure 9.
• In order to decrease dust production when drilling holes
in walls and ceilings, take actions indicated in figure 10.
• When drilling holes in glazed ceramic tiles, in order
to improve the drill centering accuracy and to save the
glaze from damage, apply adhesive tape to the pre-
sumed hole center and drill after that (see fig. 11). Start
drilling at lower speed increasing it as the hole deepens�
Screwing the screws (see fig. 12)
• To make fastening of screws easier and in order to
prevent cracking of the work pieces, first drill a hole
with a diameter equal to 2/3 of a diameter of the screw�
• If you are connecting work pieces with the help of
screws, in order to achieve durable joint without get-
ting cracks, fracturing or layering, take actions shown
in figure 12.
The manufacturer reserves the possibility to introduce changes.
Power tool maintenance /
preventive measures
