counter-clockwise
with your hand (see fig. 3) until the cams move apart
at the distance allowing an accessory to be mounted /

Mounting / dismounting of the drill chuck (see
fig. 4-5)
•
To mount the gear rim chuck
1
, carry out the op-
erations in consecutive stages as it is shown in fig-
ure 4�
•
To dismount the gear rim chuck

Attention: keep in mind that in the pro-
cess of mounting / dismounting of the
drill chuck the screw 11 has a left-hand
thread.
Initial operating of the power tool
Always use the correct supply voltage: the power sup-
ply voltage must match the information quoted on the
power tool identification plate.
Switching the power tool on / off
Short-term switching on / off
To switch on, press and hold on / off switch
8
, to switch
off - release it�
Long-term switching on / off
Switching on:
Push on / off switch
8
and lock it in the position with
lock-on button

�
Switching off:
Push and release on / off switch

Design features of the power tool
Stepless speed adjustment
Speed is controlled from 0 to maximum by
pressing force of on / off switch
8
� Weak
pressing results in low revolutions, which
enable a smooth power tool switch-on�
Speed selector thumbwheel
Use speed selector thumbwheel
7
to set required revo-
lutions�
•
Push on / off switch
8
and lock it in the position with
lock-on button

•
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
6
to the right�
Rotation to the left (unscrewing)
- move the rota-
tional direction switch
6
to the left�
Recommendations on the power tool op-
eration
Stirring various substances (see fig. 6)
Do not process explosive substances
(for example, highly inflammable sol
-
vents) and materials with ignition tem-
perature of lower than 21°С. Study the
manufacturer's instructions for such kind of mate-
rials carefully and stick to them.
•
The selection of stirring paddle type depends on the
type of substances stirred� Use stirring paddles with
left-hand blade spinning for low-viscosity substances
(dispersed paints, lacquers, sealing compounds, liquid
cement solution)� Use stirring paddles with right-hand
blade spinning for high-viscosity substances (ready-
made plastering solution, concrete, putty, polymeric
resins) (see fig. 6.1).
•
Always use additional handles, as it makes the
implementation of works more convenient and in-
creases the degree of control over the power tool�
•
Fix the container with the mixture stirred carefully
during the work�
•
Move the power tool upward, downward and in cir-
cular movements to stir the mixture in the best manner
in its whole volume (see fig. 6.2).
•
After finishing the works, wash and wipe stirring
paddle�
Drilling (see fig. 7-9)
•
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. 7.1).
