turns.
Rotate the impeller to the left (anticlockwise) to lower the impeller, DECREASING THE DOSE.
Rotate the impeller to the right (clockwise) to raise the impeller, INCREASING THE DOSE.

MAKE SURE TO LINE UP THE SCREW’S HOLE WITH THE FLAT SIDE OF THE SHAFT.
IF YOU TIGHTEN THE SCREW ON THE ROUND SIDE OF THE SHAFT, WHILE OPERATING
THE SCREW WILL LOSE GRIP AND THE GRINDER WILL SUDDENLY CRASH.
Once the proper adjustment has been made, reassemble the grinder and check for proper
operation.
