A 7 Preparations for commencingoperation

On K-Control control units EWL 4960 andEWL 4965, push mains switch £ to the"0" OFF position.Switch the K-Control Foot control unit,type 4970, to "0" OFF by letting back thefoot lever. Set sliding switch 2 or button2 for speed limitation to “max. 30,000min-1“.

Set direction switch # to “clockwise“(yellow LED does not light up) or “R“.For “counterclockwise“, the handpiecespeed is limited to about 5000 min-1.

Do not operate or lay down yourMotorhandpiece, unless an instru-

ment or the test pin is clamped in thechuck. When the chuck is open, Handpieceis locked, and inadvertent use will causethe K-Control control unit to switch tomalfunction. Malfunction indicator 1lights up or begins to flash.

A 8 Operation

Check set speed each time beforeswitching on.

Regulations for prevention of accidents areto be observed!When preselecting a speed over 30,000 min-1,button 2 should be pressed (yellow LEDlights up). This additional “enabling“serves for consciously registering the highspeed and the resultant possible dangerwhen using tools which may be unsuitable.

A 8.1 Starting K-Control knee con-trol unit EWL 4960

Preselect desired maximum speed on speedlimiter 2.

When the knee switch plate is pressed inthe direction of the arrow the speed can becontinuously regulated from 1000 min-1 tothe preselected maximum speed.

A 8.2 Starting K-Control BenchtopControl unit EWL 4965.

Preselect desired maximum speed on speedlimiter 2.

Start your Handpiece at the preselectedspeed by depressing Foot switch EWL4620 q.

A 8.3 Starting a K-Control installa-tion with the type 4970 Foot controlunit.

By pressing the foot control lever in thedirection of the arrow, the speed of theHandpiece can be regulated (enabled bysliding switch 2).

Allowing the foot lever | to return underspring pressure all the way back, stops theHandpiece.
