OPERATION

Modes of operation

Electrical Rotary Hammer has the following modes of operation:

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.
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 a switch 4. To turn switch 4 you need to unlock it by 
pressing lock 3.

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.

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. 
The working tool equipped with a shank type SDS-plus has to be installed without any effort in the opening 
of the box and cranked around its axis slightly so as to the slots of the box matched the grooves  of the shank 
(the working tool "sinks down" around 1-2 mm), then insert the tool until it stops. Special mechanism prevents 
spontaneous loss of the working tool from the box. To remove the working tool pull back the outside cup of 
the box 1 until it stops, then take out the working tool. The adapter for drill chuck is installed in Electrical Rotary 
Hammer the same way.

ATTENTION!

Before installing into the box the shank of the working tool should be lubricated with special grease.

Using the auxiliary handle

You should always use the eauxiliary handle supplied with the tool. Losing control of the tool while working may 
cause injury. 
To install the side handle 9 let loose the clamp by counterclockwise rotation of the grip, then install the handle on 
the machine in the desired angular position and fix it by clockwise rotation of the grip.

Power connection

ATTENTION!

The electric tools should be connected only to the single phase AC network which voltage 
corresponds to voltage indicated on the labels. This electric tool can be connected to sockets 
without earthing protection because it has double insulation (protection class II).
