Denzel RHV-1250-30 (26612) [7/28] Rotary hammer

ROTARY HAMMER

Power Indicator 8 burns when power is available and it is the evidence of the tool availability.

Brush indicator 9 is activated when maximum carbon brush wear-out is reached and indicates the need to contact

the service center for replacement of the brushes.

Technological hole, closed by the cover 4, used to assemble the mechanism and replenish the grease in the

mechanism. When using the tool access to this hole is not required.

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.

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

lock 5.

ATTENTION!

You can change the position of switches 2 and 7 only after the 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. It is possible to change rotation frequency with the engine running, including

under load.

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.
