Introduction
The Force 2 PCH generators are designed to provide the three most
significant electrosurgical effects: cutting, desiccation, and fulguration.
The Force 2 generator provides both monopolar and microbipolar
outputs for electrosurgery.
The monopolar outputs are designed with the capability of delivering
smooth cutting, cutting with increasing degrees of hemostasis,
desiccation, and fulguration with minimum cutting. The microbipolar
output is intended for desiccation without fulguration.
The Force 2 PCH generators are designed to provide optimal surgical
performance in procedures requiring relatively low power settings
(e.g., LLETZ, LEEP).
This manual is intended as a user's guide only. Additional technical
information and descriptions are available in the service manual.

1Patient and Operating Room Safety
The safe and effective use of electrosurgery depends to a large degree upon
factors solely under the control of the operator. There is no substitute for a
properly trained and vigilant operating room staff. It is important that the
operating instructions supplied with this or any electrosurgical equipment
be read, understood, and followed.
Electrosurgery has been used safely in numerous procedures. Before
starting any surgical procedure, the surgeon should be trained in the
particular technique and surgical procedure to be performed, should be
familiar with the medical literature related to the procedure and potential
complications, and should be familiar with the risks versus the benefits of
utilizing electrosurgery in the procedure.

1-2 Force 2 User’s Guide
General
Fire/Explosion
Warning
Always use the lowest output setting necessary that achieves the desired surgical
effect. The active electrode should be utilized only for the minimum time
necessary in order to lessen the possibility of unintended burn injury. Pediatric
applications and/or procedures performed on small anatomic structures may
require reduced power settings. The higher the current flow and the longer the
current is applied, the greater the possibility of unintended thermal damage to
tissue, especially during use on small structures.
Use electrosurgery with caution in the presence of internal or external
pacemakers. Interference produced with the use of electrosurgical devices can
cause devices such as a pacemaker to enter an asynchronous mode or can block
the pacemaker entirely. Consult the pacemaker manufacturer or hospital
cardiology department for further information when use of electrosurgical
appliances is planned in patients with cardiac pacemakers.
Valleylab recommends against the use of laparoscopic surgery on pregnant
patients.
Do not use electrosurgical equipment unless properly trained to use it in the
specific procedure being undertaken. Use by physicians without such training
has resulted in serious, unintended patient injury, including bowel perforation and
unintended, irreversible tissue necrosis.
Hazardous Electrical Output: This equipment is for use only by trained, licensed
physicians.
Caution
This equipment is capable of producing a physiological effect.
Read the warnings, cautions, and instructions provided with this generator before
using.
For surgical procedures where the current could flow through delicate parts of the
body, the use of bipolar techniques may be desirable in order to avoid unwanted
coagulation.
Danger
Explosion Hazard: Do not use in the presence of flammable anesthetics.

Fire Hazard with Oxygen Circuit Connections
Electrosurgical Smoke
1. U.S. Department of Health and Human Services. National Institute for Occupational Safety
and Health (NIOSH). Control of Smoke from Laser/Electric Surgical Procedures. HAZARD
CONTROLS, Publication No. 96-128, September, 1996.
Inadvertent Radio Frequency (RF) Burns
Warning
Fire/Explosion Hazard: The following substances will contribute to increased fire
and explosion hazards in the operating room:
• flammable substances (such as alcohol based skin prepping agents and
tinctures)
• naturally occurring flammable gases which may accumulate in body cavities
such as the bowel
• oxygen enriched atmospheres
• oxidizing agents (such as nitrous oxide [N2O] atmospheres)
The sparking and heating associated with electrosurgery can provide an ignition
source. Observe fire precautions at all times. When using electrosurgery in the
same room with any of these substances or gases, prevent their accumulation or
pooling under surgical drapes, or within the area where electrosurgery is
performed.
Warning
Fire/Explosion Hazard: Verify that all oxygen circuit connections are leak free
before and during the use of electrosurgery. Verify that endotracheal tubes are
leak free, and that the cuff is properly sealed to prevent oxygen leaks. Enriched
oxygen atmospheres may result in fires and burns to patients or surgical team.
Caution
Studies have shown that smoke generated during electrosurgical procedures can
be potentially harmful to patients and the surgical team. These studies
recommend adequately ventilating the smoke by using a surgical smoke
evacuator or other means.1
Warning
Electrodes and probes used with monitoring, stimulation, and imaging devices (or
similar equipment) can provide a path for high frequency current even if the
electrodes or probes are isolated at 50-60 Hz, insulated, and/or battery operated.
To reduce the risk of an inadvertent electrosurgical burn at the electrode or probe
site, place the electrode/probe as far away as possible from the electrosurgical
site and/or patient return electrode. Protective impedances (resistors or RF
inductors) installed in the monitoring leads may reduce the risk of such burns.
Consult the hospital biomedical engineer for further information.

1-4 Force 2 User’s Guide
Ensure Proper Connections
Active Accessories
Servicing
Do not use needles as monitoring electrodes during electrosurgical procedures.
Inadvertent electrosurgical burns may result.
In some circumstances, potential exists for alternate site burns at points of skin
contact (e.g., between the arm and the side of the body). This occurs when
electrosurgical current seeks a path to the patient return electrode which includes
the skin to skin contact point. Current passing through small skin to skin contact
points is concentrated and may cause a burn. This is true for grounded, ground
referenced, and isolated generators.
To reduce the potential for alternate site burns, do one or more of the following:
• Avoid skin to skin contact points, such as fingers touching the leg, when
positioning the patient.
• Place two to three inches of dry gauze to ensure that contact does not occur.
• Position the patient return electrode to provide a direct current route between
the surgical site and the return electrode which avoids skin to skin contact
areas.
• In addition, place patient return electrodes according to the manufacturer's
instructions.
Potential for alternate site burns increases if the return electrode is compromised.
Valleylab recommends the use of REM patient return electrodes and Valleylab
generators with the REM System.
Caution
Examine all accessories and connections to the electrosurgical generator before
using. Ensure that the accessories function as intended. Improper connection
may result in arcs and sparks, accessory malfunction, or unintended surgical
effects.
Warning
Do not wrap the accessory cords or patient return electrode cords around metal
objects. This may induce currents that could lead to shocks, fires, or injury to the
patient or surgical team.
Caution
Electrical Shock Hazard: Do not remove cover. Refer to authorized personnel for
service.
Notice
Refer to the service manual for maintenance recommendations and function and
output power verification procedures.

Valleylab recommends the use of REM patient return electrodes and
Valleylab generators with the REM system.
Warning
Electric Shock Hazard: Do not connect wet accessories to the generator.
Electric Shock Hazard: Ensure that all accessories and adapters are correctly
connected and that no metal is exposed.
Caution
Read the instructions, warnings, and cautions provided with the electrosurgical
accessories before using. Specific instructions are not included in this manual.
Connect accessories to the proper receptacle type. In particular, bipolar
accessories must be connected to the Bipolar receptacle only. Improper
connection of accessories may result in inadvertent generator activation or a
REM alarm.
Set power levels to the lowest setting before testing an accessory.
Inspect accessories and cords (especially reusable accessories and cords) for
breaks, cracks, nicks, and other damage before every use. If damaged, do not
use. Failure to observe this precaution may result in injury or electrical shock to
the patient or surgical team.
Do not reuse or resterilize accessories labeled "disposable" or "single use only."
Warning
The safe use of monopolar electrosurgery requires proper placement of the
patient return electrode. To avoid electrosurgical burns beneath the patient return
electrode, follow all directions on the product package for proper return electrode
placement and use.
Do not cut a patient return electrode to reduce size. Patient burns due to high
current density may result.
Do not apply a patient return electrode if only bipolar accessories are being used.
Otherwise, the electrosurgical effect may not be limited to the tissue between the
bipolar electrodes.
Using a conventional patient return electrode without the REM safety feature will
not activate the Valleylab REM Contact Quality Monitoring System.

Before Surgery
1-6 Force 2 User’s Guide
Generator
Some surgical instruments (e.g., colonoscopes) may allow substantial leakage
current which could burn the surgeon. If the instrument manufacturer
recommends the use of a shunt cord (s-cord) to direct the current back to the
generator, you must also use a Valleylab E0507-B adapter. To avoid a REM
alarm, you must use a REM patient return electrode with the E0507-B adapter.
Warning
Electric Shock Hazard: Connect the generator power cord to a properly
grounded receptacle. Do not use power plug adapters.
Fire Hazard: Do not use extension cords.
The instrument receptacles on this generator are designed to accept only one
instrument at a time. Do not attempt to connect more than one instrument at a
time into a given receptacle. Doing so will cause simultaneous activation of the
instruments.
Caution
Do not stack equipment on top of the generator or place the generator on top of
electrical equipment. This is an unstable configuration and does not allow for
adequate cooling.
When using a smoke evacuator in conjunction with the electrosurgical generator,
place the smoke evacuator a distance from the generator and set the generator
volume control at a level that ensures that the activation tones can be heard.
Provide as much distance as possible between the electrosurgical generator and
other electronic equipment (such as monitors). An activated electrosurgical
generator may cause interference with them.
Do not turn the activation tone down to an inaudible level. The activation tone
alerts personnel when an accessory is active.
Nonfunction of the generator may cause interruption of surgery. A backup
generator should be available for use.
Notice
If required by local codes, connect the generator to the hospital equalization
connector with an equipotential cable.
Connect the power cord to a wall receptacle having the correct voltage.
Otherwise, product damage may result.

During Surgery
Contact with Metal Objects
Generator Power Settings
Forceps
Suction Coagulators
Warning
• Contact of the active electrode with any metal will greatly increase current flow
and can result in unintended surgical effect.
• While using electrosurgery, the patient should not be allowed to come into
direct contact with grounded metal objects (e.g., surgical table frame,
instrument table, etc.). If this is not possible during certain procedures (e.g.,
those in which noninsulated head frames are used), use extreme caution to
maximize patient safety:
-Use the lowest power setting that achieves the desired effect.
-Place the patient return electrode as close to the surgical site as possible.
-Place dry gauze between the patient and the grounded object if possible.
-Continually monitor the contact point(s).
Warning
Confirm proper power settings before proceeding with surgery. Use the lowest
power setting possible for the minimum time necessary to achieve the desired
effect.
Never increase the power settings without first checking both the active electrode
and the patient return electrode and their connections. Use the active electrode
or forceps only for the minimum time necessary to achieve the desired surgical
effect in order to minimize the possibility of burns. This is especially true in
pediatric and neonatal patients or in any patient where small structures are
involved.
Caution
If the proper settings are not known, set the electrosurgical generator at a very
low setting and cautiously increase the power until the desired effect is achieved.
Notice
Do not activate the generator until the forceps have made contact with the
patient. Product damage may occur.
Warning
To avoid the possibility of a burn to the surgeon, always place the generator in the
standby mode prior to bending or reshaping the coagulator suction tube.

During Surgery
1-8 Force 2 User’s Guide
Active Accessories
Ensure that the outside of the coagulator suction tube remains free of blood and
mucus. Failure to clean the coagulator suction tube can allow electrical
conductance by means of the contaminants which may result in patient burns.
Do not immerse the suction coagulator handswitch mechanism in saline solution
or other conductive fluids. Unintended activation may result.
Warning
Do not place active accessories near or in contact with flammable materials (such
as gauze or surgical drapes). Electrosurgical accessories that are activated or hot
from use can cause a fire. Use a holster to hold electrosurgical accessories safely
away from patients, the surgical team, and flammable materials.
Simultaneously activating suction/irrigation and electrosurgical current may result
in increased arcing at the electrode tip, burns to unintended tissues, or shocks
and burns to the surgical team.
Some surgeons may elect to “buzz the hemostat” during surgical procedures. It
is not recommended, and the hazards of such a practice probably cannot be
eliminated. Burns to the surgeon’s hands are possible. To minimize the risk:
• Do not lean on the patient, the table, or the retractors while buzzing the
hemostat.
• Activate cut rather than coag. Cut has a lower voltage than coag.
• Use the lowest power setting possible for the minimum time necessary to
achieve hemostasis.
• Activate the generator after the accessory makes contact with the hemostat. Do
not arc to the hemostat.
• Firmly grasp as much of the hemostat as possible before activating the
generator. This disperses the current over a larger area and minimizes the
current concentration at the finger tips.
• "Buzz the hemostat" below hand level (as close as possible to the patient) to
reduce the opportunity for current to follow alternate paths through the
surgeon’s hands.
• When using a stainless steel blade electrode, place the flat surface against the
hemostat or other metal instrument.
• When using a coated or nonstick blade electrode, place the edge of the
electrode against the hemostat or other metal instrument.
When not using active accessories, place them in a holster or in a clean, dry,
nonconductive, and highly visible area not in contact with the patient. Inadvertent
contact with the patient may result in burns.
Caution
Studies have shown that smoke generated during electrosurgical procedures can
be potentially harmful to surgical personnel. These studies recommend using
surgical masks and ventilating the smoke by using a surgical smoke evacuator or
other means.

Patient Return Electrodes
Laparoscopic Procedures
Warning
To avoid patient burns, ensure that the patient return electrode firmly contacts the
skin. Always check the patient return electrode periodically after the patient is
repositioned and during procedures involving long periods of activation.
Warning
For laparoscopic procedures be alert to these potential hazards:
• Laparoscopic surgery may result in gas embolism due to insufflation of gas into
the abdomen.
• The electrode tip may remain hot enough to cause burns after the
electrosurgical current is deactivated.
• Inadvertent activation or movement of the activated electrode outside of the
field of vision may result in injury to the patient.
• Localized burns to the patient or physician may result from electrical currents
carried through conductive objects (such as cannulas or scopes). Electrical
current may be generated in conductive objects by direct contact with the active
electrode, or by the active accessory (electrode or cable) being in close
proximity to the conductive object.
• Do not use hybrid trocars that are comprised of both metal and plastic
components. For the operative channel, use all metal or all plastic systems. At
no time should electrical energy pass through hybrid systems. Capacitive
coupling of RF current may cause unintended burns.
• When using laparoscopic instrumentation with metal cannulas, the potential
exists for abdominal wall burns to occur due to direct electrode contact with or
capacitive coupling of RF current. This is most likely to occur in instances
where the electrosurgical generator is activated for extended periods at high
power levels and induced high current levels in the cannula.
• Ensure that the insulation of single use and reusable laparoscopic
instrumentation is intact and uncompromised. Compromised insulation may
lead to inadvertent metal to metal sparking and neuromuscular stimulation
and/or inadvertent sparking to adjacent tissue.
• Do not activate electrodes while in contact with other instruments as
unintended tissue injury may occur.
• Do not activate the generator in an open circuit condition. Activate the
generator only when the active electrode is near or in direct contact with the
target tissue to lessen the possibility of creating unintended burns.
• Use the lowest power setting that achieves the desired surgical effect and use a
low voltage waveform (cut mode) to lessen the potential for the creation of
capacitive currents.
• Carefully insert and withdraw active electrodes from cannulas to avoid possible
damage to the devices and/or injury to the patient.

Inspect the Generator
Inspect the generator for any signs of physical damage to the control
panel, base assembly and cover. Perform functional tests as specified in
the “Testing and Calibration” Section of the service manual. If physical
damage is found or the electrosurgical generator does not perform within
specifications, file a claim with the carrier. All returns must have approval
from Valleylab.
Responsibility of the Manufacturer
Valleylab is responsible for safety, reliability, and performance of the
equipment only if:
• installation procedures in this manual are followed
• assembly operations, extensions, re-adjustments, modifications or
repairs are carried out by persons authorized by Valleylab
• electrical installation of the relevant room complies with local codes
and regulatory requirements such as IEC and BSI
• equipment is used in accordance with the Valleylab instructions for use

Preparing the Generator for Use
2-2 Force 2 User’s Guide
Preparing the Generator for Use
The electrosurgical generator may be placed on a mounting cart available
from Valleylab or on any sturdy table or platform. It is recommended that
carts have conductive wheels. Refer to hospital procedures or local codes
for detailed information.
Provide at least four to six inches of space around the sides and top of the
generator for convection cooling. Under continuous use for extended
periods of time, it is normal for the top and rear panel to be warm.
Refer to the MedGV Supplement in this manual for specific MedGV
requirements.
Power Requirements
The Force 2-2 PCH Electrosurgical Generator is designed to operate at
110-120 Vac nominal, 50-60 Hz.
The Force 2-8 PCH Electrosurgical Generator is designed to operate at
220-240 Vac nominal, 50-60 Hz.
Check the Power Connector
The Force 2 generator is supplied with a hospital grade power cord and a
three-prong power connector. If using the generator in an operating room
with another type of receptacle:
• International Only – The Valleylab representative in your country will
equip your generator with the proper power cord for your country.
• Domestic Only – The hospital is responsible for replacing the
connector on the power cord.
The power connector meets all requirements for safe grounding. Its
purpose should not be defeated by using extension cords or three-prong
to two-prong adapters. Periodically check the power cord assembly for
damaged insulation or connectors. Always grasp cords by the connector.
Do not pull on the cord itself.
Danger
Explosion Hazard: Do not use in the presence of flammable anesthetics.
