4.1 Setting the
freewheel brake The freewheel brake makes it possible to wind the
compressed air hose forward or back in a con-
trolled manner. It prevents the hose unwinding off
of the viper by itself.
Fig. 27: Star knob to adjust freewheel
brake
The freewheel brake is set using the star knob
located on the left of the display.
NOTE!
The freewheel brake is set ex works; generally
speaking, it does not need to be adjusted.
To increase the braking effect

Turn the star knob clockwise.
The hose will now no longer run so easily out of
the cage.
To decrease the braking effect

Turn the star knob counterclockwise.
You will now be able to pull the hose more easily
out of the cage.
