8-2 LigaSure Vessel Sealing Generator Service Manual
Safety
Before performing any replacement procedures, read the following warnings,
cautions, and notices.
Warning
Electric Shock Hazard Only trained biomedical engineers and technicians are
authorized to service the LigaSure generator.
Electric Shock Hazard To allow stored energy to dissipate after disconnecting
power, wait at least five minutes before replacing parts.
Electric Shock Hazard Do not touch any exposed wiring or conductive surfaces
while the generator is disassembled and energized. Never wear a grounding
strap when working on an energized generator.
Fire Hazard For continued protection against fire hazard, replace fuses only with
fuses of the same type and rating as the original fuse.
Caution
The generator contains electrostatic-sensitive components. When repairing the
generator, work at a static-control workstation. Wear a grounding strap when
handling electrostatic-sensitive components, except when working on an
energized generator. Handle circuit boards by their nonconductive edges. Use an
antistatic container for transport of electrostatic-sensitive components and circuit
boards.
Notice
Calibrate the generator after installing a new battery. Internal memory loses
calibration values when you remove the battery. Refer to Chapter 6, Calibrating
the LigaSure Generator for instructions.
Calibrate the generator after you install a new RF board, heat sink, or
components on the heat sink. Component differences may affect output
waveforms. Refer to Chapter 6, Calibrating the LigaSure Generator for
instructions.
