ROTARY HAMMER

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.

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 xing 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 "o" 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 eective.

The working tool equipped with a shank type SDS-Plus has to be installed without any eort 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.
