Speed variation

Speed adjustment hand lever
ATTENTION!
Changing the speed while the drill spindle is stationary will damage the variable speed
gear. Always change the speed only when the drill spindle is turning.
The drilling machine has a motor with a continuously variable mechanical transmission. With
the infinitely variable V-belt drive, the V-belt is positioned to the required V-belt diameter with
the hand lever (15) while the drill spindle is rotating. This changes the speed. The lower the
spindle speed during adjustment, the more difficult it is to turn the hand lever.
