Impact Drill
10
Impact drilling:
To switch to this operation mode, turn
switch 5 so that the Impact drilling
sign coincides with the mark on the
body.
One can switch to another operation mode
without stopping the power tool, simply
decrease pressure applied to it to some
extent.
Stepless speed adjustment
Speed is controlled from O to max-
imum by pressing force of on / off
switch 9 . Weak pressing results in
low revolutions, which enable a smooth power
tool switch-on.
Speed selector thumbwheel
Use speed control 8 to set required revolu-
tions and impact frequency.
► Push on / off switch 9 and lock it in the po-
sition with lock-on button 10 .
► Set the needed speed.
The required speed is dependent on the ma-
terial and can be determined with practical
trials. When operating your power tool at a
low speed for a long time, it has to be cooled
down for 3 minutes. To do it, set a maximum
speed and leave your power tool to run idle.
Step speed selector switch
Attention: one can only change
the revolutions per minute range
after the engine fully stops.
The first speed - you can find the
values of the revolutions per minute
range in the technical specifi cations
table.
The second speed - you can find
the values of the revolutions per
minute range in the technical speci-
fi cations table.
Changing the rotational directions
Change the direction of rotation
only & after a full stop of the mo-
tor, acting otherwise may cause
damage to the power tool.
Rotation to the right (drilling, screwing in)
-
move the rotational direction switch
7
to the
right.
Rotation to the left (unscrewing) -
move the
rotational direction switch
7
to the left.
Recommendations on the power
tool operation
Drilling (see fi g. 8-11)
► Grease the drill bit regularly when drilling
holes in metals (except drilling non-ferrous
metals and their alloys).
► When drilling hard metals, apply more
force to the power tool and lower the rota-
tion speed.
► When drilling large diameter holes in met-
al, fi rst drill a hole with a smaller diameter
and ream it till the necessary diameter (see
fi g. 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
fi gure 9.
► In order to decrease dust production when
drilling holes in walls and ceilings, take ac-
tions indicated in fi g. 10.
► When drilling holes in glazed ceramic tiles,
in order to improve the drill centering accu-
racy and to save the glaze from damage,
apply adhesive tape to the presumed hole
center and drill after that (see fig. 11 ).
Start drilling at lower speed increasing it as
the hole deepens. Caution: drill tiles in
the impactless drilling operation mode
only.
Impact drilling
During the impact drilling, the result does not
depend on the pressure applied to the power
tool this is caused due to the peculiarities in
the impact mechanism design. That is why
you should not apply excessive pressure to
the power tool it can jam the drill and overload
the engine.
Screwing the screws (see fi g. 12)
► To make fastening of screws easier and in
order to prevent cracking of the work piec-
es, fi rst 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 getting cracks, fracturing or
layering, take actions shown in fi gure 12 .
Power tool maintenance / preven-
tive measures
Before carrying out any works on the pow-
er tool it must be disconnected from the
mains.
Cleaning of the power tool
An indispensable condition for a safe long-
term exploitation of the power tool is to keep
it clean. Regularly flush the power tool with
compressed air thought the ventilation slots
6
.
Transportation of the power tools
► Categorically not to drop any mechanical
impact on the packaging during transport.
