Use speed selector thumbwheel 7 to set required revo-
lutions.
• 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 16.
• Push on / off switch 6 and lock it in the position with
lock-on button 5.
• Set the needed speed.
Power tool maintenance / preventive
measures
Before carrying out any works on the power tool it
must be disconnected from the mains.
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.
Cleaning of the power tool
Changing the rotational directions
Change the direction of rotation only after
a full stop of the motor, acting otherwise
may cause damage to 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 3.
After-sales service and application service
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.
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

Recommendations on the power tool
operation
Transportation of the power tools
Drilling (see fig. 12-15)
• 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.
These instructions are printed on recycled paper man-
ufactured without chlorine.
• 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. 12.1).
• 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 12.2.
• In order to decrease dust production when drilling holes
in walls and ceilings, take actions indicated in fig. 13-14.
• 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. 15).
Start drilling at lower speed increasing it as the hole
deepens.
