Releasing wheel in case of blocked lid
Note:
When the lid is in the extreme up or down position, it may happen that the wheel is
uncoupled. In this situation the clutch mechanism is active in both directions (clicking noise in
either direction). To unlock wheel, press metal pin with a ballpen and turn wheel carefully. This
pin overcomes the automatic clutch mechanism. Thus, care must be taken not to apply excessive
pressure.
Lid arrested in upper
position:
carefully turn wheel with
pressed pin clockwise, until
you feel normal resistance (no
more clicking noise, clutch is
released). Release pin and
turn lid down, until the clutch
mechanism is activated
(clicking noise, optimum
pressure applied).
Lid arrested in down
position:
carefully turn wheel with
pressed pin counter
clockwise, until you feel
normal resistance (no more
clicking noise, clutch is
released). Release pin and
turn wheel counter clockwise
until pressure is completely
released. Open lid.
IMPORTANT: WHEN THE CLUTCH MECHANISM IS ACTIVE (OPTIMUM
PRESSURE IS APPLIED), NEVER USE PIN TO FURTHER INCREASE PRESSURE.
THIS WILL LEAD TO DAMAGE OF TUBES AND INSTRUMENT!
