1.0 MEANING OF SAFETY SIGNAL WORDS
A safety related message is identified by a safety alert symbol and a signal word to indicate the level of risk involved with a particular
hazard. Per ANSI standard Z535.6, the definitions of the four signal words are as follows:
DANGER DANGER indicates a hazardous situation which, if not avoided, will result in death or serious
injury.
WARNING WARNING indicates a hazardous situation which, if not avoided, could result in death or serious
injury.
CAUTION CAUTION indicates a potentially hazardous situation which, if not avoided, could result in minor
or moderate injury.
NOTICE NOTICE is used to address practices not related to physical injury.
2.0 SAFETY
DANGER Hydraulic tools can apply many tons of force which can bend, move, or lift large loads storing
potential energy. Loads can become unstable and suddenly move without warning causing
severe injury or death. Never support a load solely by a rescue tool. Use secondary supports to
limit the extent of uncontrolled movements. Never put body parts in a situation where a shifting
or falling load can cause a crushing injury. Stay clear of the path of travel.
• Metal-on-metal contact is likely to slide sideways when the load is not able to deform around
the area of contact. Use care when lifting structural and hardened objects.
• Chains can break when overloaded or improperly loaded.
• Spreader tips and rams can kick (move) when direction of force isn’t perpendicular to load
• Loads can suddenly shift sideways when forced, lifted, or moved. Stabilize load to reduce risk
of movement from ice, gravel, soft ground, precarious positions, objects which can break,
wheels which depressurize or roll, and loading which can change during rescue operations.
WARNING Operating rescue tools can result in injury or death from laceration, projectile (high speed
flying debris), and pinch point injuries. Stay clear of the path of travel. Avoid unnecessary risk.
Examples include:
• Never lift, or hold a rescue tool by its cutting blades or spreader arms. Never place hands
between moving tool and a load. Pinch points are created from tool movement causing risk of
limb amputation (i.e. fingers, hands, arms, feet, legs).
• Sharp metal objects formed during cutting and extrication cause potential for laceration and
puncture wounds
• Projectiles can be ejected during cutting, spreading, or lifting operations when objects break
suddenly under load. Sudden fractures are common with springs and hardened steels.
• Damaging pressurized objects such as airbag cylinders can create projectiles.
• Using a rescue tool beyond its reasonable lifespan increases risk of fatigue failure. Expected
lifetime of the tool is 10 years from the date of manufacture.
• Tools can drift (move side-to-side) as load is applied or released resulting in body parts being
trapped and crushed between tool handles and stationary objects. Always be aware of body,
hand, and finger position. Stop before harmful contact is made.
WARNING Using rescue tools can cause ignition or explosion resulting in injury or death. Ignition or
explosion can result from situations such as:
• Flammable hazards are created when fuel lines, refrigerant lines (atomized oil), or pressurized
hydraulic fluid lines are breached. Ignition sources can suddenly ignite these fuels.
• Flammable vapors can be released by careless refueling or operation of gasoline driven
engines. Refer to engine manufacturer’s manuals for specific details.
• Extrication tools can create sparks as metals are cut and deformed. Avoid unnecessary risk
when flammable vapors are present.
• Power units with electric motors or internal combustion engines are ignition sources.
• Flammable vapors heavier than air can accumulate in low spots. Avoid selecting these
locations when setting up the power units. Use detectors to verify safe site selection.

WARNING Hydraulic fluid (mineral oil) escaping under pressure can puncture the skin, infiltrate eyes, or
lungs resulting in serious injury. Seek medical attention immediately. Avoid the urge to contain
leaks with hands. Injection injuries require immediate medical attention. Safety Data Sheet (SDS)
for AMKUS MV1 and AMKUS MV0 Hydraulic Fluid is available at AMKUS.com and CHEMTREC.
com Hydraulic leaks can occur from situations such as:
• Leaks at hose crimps and connections can develop from constant use, over-pressurization,
side-loading, or mis-crimping.
• Hose damage from being driven over, stepped on, twisted, kinked, crushed, excessive
vibration, abuse, or neglect.
• Leaks and breaks in hydraulic components can occur from improper maintenance or exceeding
service life expectations. Establish sound practices.
• Connecting hydraulic tools in series can pressurize both sides of double acting cylinders.
Each tool must be separately connected to a power unit.
• Release stored pressure before servicing tools by moving offend stops. Refer to power unit
manuals for proper operation.
WARNING Electric shock can result in injury or death. Rescue tools are made from metal which is a conductor
of electricity. Electric current can flow from the hazard through the rescue tool to shock nearby
people. Maintain awareness of potential hazards. Examples include:
• Never operate electric power units with damaged power cords.
• Do not drive over or crush power cords.
• Use care to avoid cutting power cords on sharp objects.
• Do not strain cords during storage. Hidden cord damage can remain undetected until wet
conditions create an electrocution hazard.
• Power sources and electronics are not waterproof. Do not submerge or douse the power units
or controls. Refer to manuals from battery, charger, and motor manufacturers for specific
details.
• Cutting into concealed spaces can be hazardous. Power cables and battery packs may be
hidden from view in structures and electric vehicles.
• Never operate near damaged electric power lines before power is verified as OFF
WARNING Misuse of AMKUS Rescue Systems can result in a wide variety of hazards and consequences.
Remain aware of and avoid misuse situations. Examples of misuse include:
• Using low pressure (5000 psi) tools on high pressure (10,500 psi) hydraulic power units
creates high risk of hydraulic cylinder rupture. Ensure compatibility before use.
• Failure to inspect and properly maintain rescue equipment. Inspect all rescue equipment after
each use. Any equipment found damaged or inoperable should be removed from service.
• Storage of rescue equipment in adverse conditions. Always store rescue equipment in
clean,dry, and secure conditions.
• Operation of rescue equipment with missing or illegible safety markings
• Modification of tools and power units inconsistent with manufacturer’s specifications
• Repairs attempted by unqualified workers.
• Use of rescue tools for non-rescue purposes such as construction, production use, demolition,
or as a jack for vehicle service.
• Pressure relief valve set over +5% above the Rated Output Pressure 10,500 psi (724 bar)
• Using tools which have been heat damaged. Heating beyond 212°F (100°C) will compromise
the strength.
CAUTION Lifting or moving rescue tools and power units can result in falling or spine injury. Rescue tools
and power units are heavy. Risk of injury increases in unfavorable conditions such as poor
lighting, inclines, loose, wet, or icy surfaces. Follow accepted safe lifting practices.
NOTICE Use of hydraulic fluids other than AMKUS MV1 or MV0 (see Specifications for fluid for specific
tool lines) can result in equipment damage and loss of function. Some examples include:
• Phosphate ester hydraulic fluids and blends are incompatible with Buna-N seal and hose
materials used in AMKUS Rescue Systems
• Mixing glycol with mineral oils can result in gelling and plugging of pump inlet screens
• Using fluids with wrong viscosity or wear properties. Always use AMKUS MV1 or MV0 as
specified for your tools.

5.0 SAFETY CONSIDERATIONS
5.1 PROTECTIVE CLOTHING
WARNING Tool operators bear responsibility for ensuring use of appropriate protective clothing and
equipment. The chosen protective clothing and equipment must provide protection from potential
hazards users may encounter while operating AMKUS rescue tools. Requirements for protective
clothing and equipment are determined by the Authority Having Jurisdiction (AHJ).
5.2 TRAINING
AMKUS tools facilitate the extrication of entrapment victims. Only trained emergency services personnel should attempt victim
extrication. All personnel using AMKUS rescue tools are assumed to have completed a training course covering safe extrication of
entrapment victims. The training must be acknowledged as educationally sound by the local Authority Having Jurisdiction (AHJ) over
such training.
5.3 OPERATING CONSIDERATIONS
NOTICE AMKUS tools are intended for intermittent use. Allow sufficiently long pauses for the rescue
tool to cool. If the tool’s exterior becomes too hot to touch, the temperature is likely above 120°F
(49°C). An overheated rescue tool operates less effectively. When hydraulic oil temperature
reaches 158°F (70°C), the tool’s efficiency drops significantly, and the tool should be stopped to
cool down.
To avoid rescue tool overheating:
• After use, clean offany accumulated oil, grease, dirt, or corrosive substances with a damp cloth and soapy water.
NOTICE Operating the rescue tool continuously against an end stop may cause overheating resulting
in an inoperable tool. Permanent damage to the tool may occur. When an end stop is reached,
release the control handle to return the control to the neutral position.
6.0 SET-UP PROCEDURE
Normally, AMKUS equipment is prepared and serviced by your dealer prior to delivery. If, however, you have decided to place the
equipment into service yourself, remove equipment from the packing cartons and carefully inspect for damage. Damage that occurs
during shipment should be reported immediately to the carrier.
1. Gather and review all safety and use documentation prior to operating any rescue tool.
2. Connect the tool connection hoses to the hose lines from the AMKUS hydraulic power unit.
A. Standard Couplings: Please note that the male and female couplings on the hose lines leading from the power unit should
be connected to the corresponding male and female couplings on the tool connection hoses. To connect the couplings, twist
the sleeve on the female coupling so that the notch in the sleeve lines up with the pin. Push the sleeve back so the pin fits
into the notch. While holding the sleeve back, push the male coupling into the female coupling. Release the sleeve; it will
spring forward into place. Twist the sleeve 1/4 turn so that the pin no longer lines up with the notch. Pull on the couplings to
check that they are securely connected.
B. Mono Couplings: Please note that the female coupling on the hose lines leading from the power unit should be connected
to the corresponding male coupling on the tool connection hoses. To connect the couplings, place the male coupling into
the female coupling. Rotate clockwise until you feel the coupling latch. Pull on the couplings to check that they are securely
connected.
In most cases, the Mono Couplings can be connected and disconnected while the hose line is under flow. It is usually not
necessary to place the directional control of the power unit in the neutral position before connecting and disconnecting.
However, certain circumstances such as back pressure in the return line and/or cold temperatures, may make connecting
and disconnecting under flow extremely difficult or impossible. If you are unable to connect and disconnect while the line is
under flow, place the directional control valve of the power unit in the neutral position and then disconnect or connect.

Figure 6.1.1
7.0 OPERATION
WARNING Do not connect tools in series. Connecting tools in series could cause operational problems,
equipment failure, or catastrophic failure of the equipment resulting in serious injury or death.
Start the power unit (refer to power unit and engine manuals). Following the instructions in the power unit manual, operate the
selector valve to charge the hose line to which the tool is connected. Pick up the tool, noticing that the design of the cutter makes it
natural to grip the handle with one hand and the control valve hand grip with the other.
7.1 CONTROL VALVE ACTUATOR
The control valve actuator has three positions, OPEN, OFF, and CLOSE. The control valve actuator includes a deadman safety
feature which returns the control valve actuator to the OFF position (neutral) when released. When the control valve is in the OFF
position, the tool movement stops, and holds position and load. Verify operation of control valve actuator by checking to see it returns
automatically to the neutral position when released.
7.2 CUTTING
Rotating the control valve actuator regulates the hydraulic flow rate and power delivered to the tool. Turning the control valve actuator
to the end stops provides maximum hydraulic flow rate and power.
Figure 7.2

©Copyright AMKUS Rescue Systems, Inc. 2020 LAL-001 August 11, 2020 Rev01
11
7.2 CUTTING (CONTINUED)
To perform a cutting operation, first, open the cutter blades. Place the blades around the object being cut. Close the blades to cut the
object. Obtain the maximum cutting forces nearest the pivot point. Start the cut with the blades as fully engaged as possible. Make
the cut. Open the blades and remove the tool when finished.
WARNING When operating the cutter, take care to be positioned to the side of the cutter. As the cutter blades
meet resistance, the rescue tool may rotate or drift. If tool rotation places the user, operator, or
others in jeopardy, immediately release the control valve actuator. The deadman safety feature
of the control valve actuator should immediately return the control valve actuator to the center
(neutral) position stopping blade movement. Reposition the cutter as needed for optimal cutting
performance.
WARNING Blades can break if positioned incorrectly, causing hazardous projectiles and an inoperable tool.
If blades start to flex sideways (tool rolls as space between blades increases), stop immediately
and reconsider cutting strategies.
CAUTION The blades on AMKUS cutters effectively cut steering columns, brake pedals, door mechanisms,
and other vehicle items as necessary for extrication. However, using AMKUS cutters as a piercing
tool for heavy metal is not recommended. Therefore, when cutting, take care to insure the blade
tips move through a clear path of travel. The blade tips can pierce automotive sheet metal body
panels. Avoid obstacles like the heavy metal backing plates hidden behind seat belt mounts,
door hinges, and latching mechanisms or locks.
NOTICE Cutting hardened metals can potentially dent or deform the blade’s cutting edge. Blades may
break at these weak spots on subsequent cuts, especially if cutting near the tips. Avoid cutting
hardened solids of unknown strength such as:
• Padlock shackles
• Tie rods
• Leaf springs
• Spindles
• Hardened bolts
• Tool steel
• Heat treated chain
Blade damage or breakage that results from cutting hardened metals or solids is not covered by
the AMKUS Rescue Systems warranty.
The blades are intended and designed to cut hardened auto bodies and components without
damage.
We recommend an Authorized AMKUS Rescue Systems Dealer inspect, evaluate, and replace
dented or damaged blades as necessary.

7.3 SPREADING / SQUEEZING / LIFTING
Rotating the control valve actuator regulates the hydraulic flow rate and power delivered to the tool. Turning the control valve actuator
to the end stops provides maximum hydraulic flow rate and power.
Figure 7.3A
WARNING When operating the spreader, the tool may rotate as it meets resistance. If tool rotation places
the user, operator, or others in jeopardy, immediately release the control valve actuator. Stop and
modify the extrication procedure. The deadman safety feature returns the control valve actuator
to the center (neutral) position stopping arm movement. Seek another purchase point to proceed
with the extrication.
WARNING Spreading, squeezing, pulling, and lifting operations can cause loads to become unstable.
Unstable loads can cause injury or death. To avoid load instability:
• Position the spreader tips to maintain maximum contact with the surfaces to be spread,
gripped or lifted.
• Always stabilize the object being lifted.

8.0 ACCESSORIES
8.1 EXTENDED REACH SPREADER TIPS (ERT)
The spreaders use removable tips. To remove the spreader tip, use a thumb and finger to depress the spring loaded tip pins, and
remove the tips. To re-install the spreader tip, slide the tip back into place. Be sure that both pins return fully to their original positions.
The reach and versatility of the spreader can be increased by using the Extended Reach Tips (ERT). ERT tips are interchangeable
with the standard tips.

8.2 CHAIN USE
WARNING Transport chain is NOT rated for overhead lifting. Injury or death may occur from improper chain
use. Observe chain safety guidelines established by the Authority Having Jurisdiction.
Chain kits are available for spreaders.
Setup and operation of the chain kit:
• Secure chains around the load removing slack using grab hooks
to latch fully across the chain (tip of hook must not be inserted
into holes of the chain link)
• Remove slack in the chain using quick adjust links (spreader)
• Tension the chain slightly and check to see that the connections
are stable and safe
• Activate the control valve actuator to close the arms and draw
the load
