Set the needed speed�

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�

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.

Rotation  to  the  right  (drilling,  screwing  in)

 - move 

the rotational direction switch

Recommendations  on  the  power  tool 

operation

Drilling (see fig. 12-15)

•

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�

Screwing the screws (see fig. 16)

•

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.

Power  tool  maintenance  /  preventive 

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
