or loop fastener is secured to the carriage.
Check for proper labeling. Make sure that the
Femur adjustment decals are in good condition.
Verify that the serial decal for the unit is present.
Verify that the LCD lens is in good condition and
clean if necessary.
Verify that the domed heads of the femur hinge
rivets are in good condition. Make sure that
the hinges are secure, by attempting to pull them
apart.
A unit failing dielectric withstand and/or leakage
tests could indicate serious internal system
problems. Do not place unit back into service.
Contact the factory for repair. Do not attempt to
repair the unit in the field.
5.4 FUNCTIONAL INSPECTION
Check the calibration of the unit by running it
successively through its full ROM with femur length
adjusted first to maximum and then to its
minimum length.
This unit must not be operated with any
adapter attached to the three prong plug
that would disable the earth connection.
Disruption of the earth connection may cause
unit damage, malfunction, electrical shock, fire,
or personal injury.
NOTE:
Verify that the lead screw is unobstructed and no
abnormal noises are present during operation.
Pull out the pendant while the unit is running to
verify that the unit will stop.
