In order to choose the "LOW" gear, move the switch 4
back� This mode is used for the fastening of screws or
for large diameter hole drilling�
In order to choose the "HI" gear, move the switch 4
forward� This mode is used for speed drilling of small
diameter holes�
Stepless speed adjustment
Speed is controlled from 0 to maximum by
pressing force of on / off switch 7� Weak
pressing results in low revolutions, which
enable a smooth power tool switch-on�
Changing the rotational directions (see fig. 7)
Change the direction of rotation only after
a full stop of the motor, acting otherwise
may cause damage to the power tool.
Clockwise rotation (drilling, fastening of screws) -
move the rotational direction switch 6 to the left as it is
shown in fig. 7.1.
Counter
clockwise
screws) - move the rotational direction switch 6 to the
right as it is shown in fig. 7.2.
Spindle automatic locking
If the on / off switch 7 is not pressed, the spindle of the
power tool is locked this enables to use the power tool
as an ordinary screwdriver (for example it can be used
to tighten manually screws or bolts)�
Light-emitting diode
When the power tool is connected to the mains, the
LED 8 operates in an indicator mode (low light) and
shows that the power tool is ready to be turned on�
When you press the on / off switch 7, the LED 8 oper-
ates in a mode of light (strong light) it allows you to
work in low light conditions�
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
fig. 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 presumed hole
center and drill after that (see fig. 11). Start drilling at low-
er speed increasing it as the hole deepens� Caution: for
rotation

model CT10152F - drill tiles in the impactless drilling
operation mode only.
Impact drilling
[CT10152F]
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. 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.
Power tool maintenance / preventive
the
measures
Before carrying out any works on the power tool it
must be disconnected from the mains�
Cleaning of the power tool
An indispensable condition for a safe long-term exploi-
tation of the power tool is to keep it clean� Regularly
flush the power tool with compressed air thought the
ventilation slots 5�
After-sales service and application service
Our after-sales service responds to your questions
concerning maintenance and repair of your product as
well as spare parts� Information about service centers,
parts diagrams and information about spare parts can

Transportation of the power tools
• Categorically not to drop any mechanical impact on
the packaging during transport�
• When unloading / loading is not allowed to use any
kind of technology that works on the principle of clamp-
ing packaging�
Environmental protection
Recycle raw materials instead of dispos-
ing as waste.
Power tool, accessories and packaging
should be sorted for environment-friendly
recycling�
The plastic components are labelled for categorized
recycling�
