In the event of power failure, it may be impossible to unlock the lid by
conventional means. In this case, entry into the rotor chamber may be
made by removing the latch label and using a
pen to manually disengage the locking
mechanism (see photo). Pull the mechanism
towards the control panel and then unlatch
and open the lid. If the unit is damaged,
contact your authorized dealer or Drucker
Diagnostics.

ESTING
It is recommended that the top speed be tested every two years for
continued safe operation. Contact Drucker Diagnostics for further

AFETY
The Model 642B complies with US, Canadian, and European Safety standards.
Lid Safety Switch
: The Model 642B lid is secured to the top of the cabinet
by a latching knob and pawl system. When the knob is rotated clockwise,
the pawl grips the underside of the cabinet opening and prevents the lid
from opening. A mechanical stop positions the pawl and prevents it from
rotating completely. When rotated to the stop position, the pawl makes
contact with a micro–switch mounted underneath the cabinet top. The lid
safety switch prevents the centrifuge from operating while the lid is open.
Note:
After the centrifuge has started spinning, it may be possible
to rotate the lid knob enough to cause the pawl to lose contact
with the lid safety switch. If this happens, the centrifuge motor
may lose power. If the knob is accidentally moved and this
situation should occur, rotate the knob fully clockwise to its stop
position and the centrifuge will resume operation.
Circuit Breaker
: The Model 642B is protected with a 4 Amp circuit breaker
located at the rear of the machine mounted to the base. Any electrical
short circuit will cause the breaker to cut power to the machine.
