Design features 

of the power tool

Changing the rotational directions (see fig. 6)

Change  the  direction  of  rotation  only 

after a full stop of the motor, acting oth-

erwise  may  cause  damage  to  the  power 

tool.

Recommendations

on the power tool operation

Stirring various substances (see fig. 7-8)

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. 7).

•

Always use additional handle 

3

, 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. 8).

• After  finishing  the  works,  wash  and  wipe  stirring 

paddle�

Drilling (see fig. 9-10)

•

Grease the drill bit regularly when drilling holes in 

metals (except drilling non-ferrous metals and their al-

loys)�

• 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. 9).

•

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, take actions indicated in figure 10.

•

When drilling holes in glazed ceramic tiles, in order 

to improve the drill centering accuracy and to save the
