CORDLESS DRILL/DRIVER 

EN

Switching speeds / modes

Switching is carried out using the switch 3 (pic. 1). The switch has two positions, indicated by numbers «1» и «2».
Position "1" corresponds to a lower speed of rotation of the chuck; this mode is designed for screwing and 
unscrewing screws and other works, requiring the application of significant torque. In this position of the switch 
tool develops maximum torque.
Position "2" corresponds to the increased speed of rotation of the chuck; this mode is designed to perform the 
most efficient drilling. The maximum torque at this position of the switch is less than at the position "1".
In case, the switch 3 does not reach the end position, you need to bring it back, turn the machine on and off by 
briefly pressing the switch, perform a speed change after stopping the engine.

ATTENTION! 

Do not switch speed until the spindle stops. Always send the switch 3 key to the end, do not 

leave it in an intermediate position. Failure to follow instructions may cause damage to the 

gearbox.

Torque adjustment

Torque adjustment function allows you to choose the optimal effort of tightening screws, depending on their size 
and working conditions. The choice of the optimal tightening force is carried out empirically.
Change of the torque is carried out by setting ring 2 to the position indicated by the arrow located at the top of 
the case.

– positions 1… 21 serve for screwing in / out screws, however, a higher number corresponds to a higher torque;

– position   is for drilling, wherein torque limiting function is blocked.

NOTE. Numeric values indicated on the ring 2 (pic. 1) do not reflect torque values expressed in Nm, and indicate 
the ordinal position of the adjustment ring.

Light of the working area

LED light of working area turns on simultaneously with the engine when you press the switch key.

Replacement of tooling

ATTENTION! 

Before changing the tooling, remove the battery from the tool or set the switch of the direction 

of rotation to the middle position to prevent accidental activation of the tool and injury.

To open the chuck, turn the outer ring of its sleeve counterclockwise (when viewed from the front) until the tool 
shank is positioned freely between the chuck jaws.
Install the tooling in the chuck, use a tooling with a cylindrical or hex shank with a diameter from 2 to 13 mm. 
Tooling with a shank less than 2 mm cannot be properly centered in this chuck. 
Clamp the chuck by turning its outer ring clockwise. 
Make a trial tool enable to make sure that the tooling is installed and centered.

NOISE AND VIBRATION

Noise and vibration characteristics are given in the table №1.
However, if the Electrical Rotary Hammer will be used for other work with the use of working tools, not provided 
by the manufacturer, or maintenance will not meet the requirements, then the vibration level may be different.
