Speed selector thumbwheel
Use speed control 7 to set required revolutions and
impact frequency.
Attention: keep in mind that in the pro
cess of mounting / dismounting of the
drill chuck the screw 12 has a left-hand
thread.
Screwdriver bit / magnetic holder (see fig. 13)
•• Push on / off switch 9 and lock it in the position with
lock-on button 8.
•• Set the needed speed.
When using the power tool as a screwdriver, use
magnetic holder 14 for reliable locking of screwdriv
er bits 13 (see fig. 13). A magnetic holder 14 is not
needed for extended screwdriver bits 13 (specially pur
posed for screwdrivers).
The required speed is dependent on the material 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.
Initial operating of the power tool
Changing the rotational directions
Always use the correct supply voltage: the power sup
ply voltage must match the information quoted on the
power tool identification plate.
Change the direction of rotation only after
a full stop of the motor, acting otherwise
may cause damage to the power tool.
Switching the power tool on / off
Rotation to the right (drilling, screwing in) - move
the rotational direction switch 6 to the right.
Short-term switching on / off
Rotation to the left (unscrewing) - move the rota
tional direction switch 6 to the left.
To switch on, press and hold on / off switch 9, to switch
off - release it.
Long-term switching on / off
Recommendations on the power tool
operation
Drilling (see fig. 14-17)
Switching on:
Push on / off switch 9 and lock it in the position with
lock-on button 8.
Switching off:
Push and release on / off switch 9.
•• Grease the drill bit regularly when drilling holes in
metals (except drilling non-ferrous metals and their al
loys).
•• When drilling hard metals, apply more force to the
power tool and lower the rotation speed.
Design features of the power tool
"Impact / drill" switch
•• 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. 14).
Switch 4 is purposed for switching between the follow
ing operation modes of the power tool:
•• 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 14.
•• drilling, screwing, unscrewing - drilling without
impact in wood, synthetic materials, metal. Screwing
and unscrewing fastening components;
•• In order to decrease dust production when drilling
holes in walls and ceilings, take actions indicated in
fig. 15-16.
•• impact drilling - impact drilling in brick, concrete,
natural stone.
Drilling, screwing, unscrewing:
To switch to this operation mode, move
switch 4 right to the stop.
•• 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. 17). Start
drilling at lower speed increasing it as the hole deep
ens. Caution: drill tiles in the impactless drilling
operation mode only.
Impact drilling
Impact drilling:
To switch to this operation mode, move
switch 4 left to the stop.
One can switch to another operation mode without
stopping the power tool, simply decrease pressure
applied to it to some extent.
Stepless speed adjustment
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 mecha
nism design. That is why you should not apply exces
sive pressure to the power tool - it can jam the drill and
overload the engine.
Screwing the screws (see fig. 18)
Speed is controlled from 0 to maximum by
pressing force of on / off switch 9. Weak
pressing results in low revolutions, which
enable a smooth power tool switch-on.
•• To make fastening of screws easier and in order
to prevent cracking of the work pieces, first drill a
