OPERATION
Modes of operation
Electrical Rotary Hammer has the following modes of operation:
Drilling.
The mode is intended for the use of a drill chuck with SDS-plus adapter (not included in the
set) or special drills with an SDS-plus shank.
Drilling with impact.
In this mode it is necessary to use only a special shockproof working tool with a shank SDS-
plus. Adapters are not allowed.
Chiseling (impact with no rotation).
In this mode it is necessary to use only a special shockproof working tool with an SDS-plus
shank. Adapters are not allowed.
Adjusting of the angular position of the tool.
It is not an operating mode, switch position is intended to install a convenient angular
position of the tooling.
The modes of operation switching are carried out using switch 2. To turn the switch 2 you need to unlock it by
pressing the lock 3
ATTENTION!
You can change the switch position 2 only after complete stop of the engine.
Adjustment and setting of the working tool rotational speed
Electrical Rotary Hammer has the ability to change smoothly the working tool rotational speed from minimum
to maximum by changing key pressure on the switch 6. You can change the speed of rotation with the engine
running in the process of working. The key 6 of the switch can be locked in the "on" by pressing the fixing button 7.
To unlock the key 6 press it again.
Using the regulator 11 you can change the working tool rotational speed when the key 6 being in the "on" position
is blocked.
Electrical Rotary Hammer also has the ability to change direction of rotation of the working tool on the opposite
with the switch 8.
ATTENTION!
You can change a position of the direction of rotation switch 8 only after complete stop of the
engine and if the key of the switch 6 is in the «off» position.
Installation of the working tooling
Electrical Rotary Hammer is designed to work with the working tool equipped with a shank of a special type SDS-
plus which is installed in the receiving device (box) 1. The box construction provides a torque transmission on the
working tool and a possibility of displacement of the working tool axis on 5-10 mm in order to make an energy
transfer impact more effective.
