(“R” means clockwise). The electric drive motor is equipped with an additional 2-
stage mechanically switching gear. The switch for the mechanical gear is located
on the bottom side of the electric drive motor. The switch is marked with a turtle
and a rabbit. The turtle means high ratio (maximum speed = 245 rpm, high torque).
The rabbit means low ratio (max. speed = 700 rpm, lower torque).
The speeds marked on the electric drive housing indicate the speed of the electric
drive motor itself and not the speed of the valve grinder’s spindle. To get the spin-
dle speed of the valve grinder, these figures have to be divided by 5,4.
The electric drive motor also has a switch for a percussion drill function. This
switch is located at the side of the electric drive housing. However, for the general
function of the valve grinder, this switch and its function is not required.
The machine should always run in drilling mode (symbol = drill) and never in per-
cussion drill function (symbol = hammer).

The spindle speed is activated by pushing the red safety button of the maintenance
unit to its upper position. The speed can be adjusted by the regulating knob on the
maintenance unit. The operating pressure is indicated at the gauge on the mainte-
nance unit. If customer is using his own maintenance unit, the operation might be
different, however, the basic operating buttons should be provided.
CAUTION
The operating pressure of the machine is 6,3 bar. Higher
pressure can result in damaging the machine and therefore, it is
