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 Z535.6, the definitions of the four signal words are as follows:
2.0 SAFETY
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.
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, spreader arms, or ram pistons. 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 off end 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 technicians.
• 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.

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).
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.
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.

©Copyright AMKUS Rescue Systems 2020-2021 9 LAL-002 August 3, 2021 Rev01
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.
6.1 ROTATING HANDLE
Cutter and Combi Tools come equipped with a 360° swiveling handle that has variable tension.
Figure 6.1
6.1.1 HANDLE LIGHTS
AMKUS dual handle lights operate in one of two modes, an on/off mode (standard), or an optional mode with three intensity levels.
To operate the lights in the on/off mode, press the power button to turn the lights on. Press the button again to turn off.
To operate the lights in the three intensity level mode, press the power button to turn the lights on. Press the button to scroll through the
three intensity levels and then off.
To change between operating modes:
1. Press the button once to turn on the lights.
2. Press and hold the button until the lights flash.
3. The lights now operate in the alternate mode.
7.0 OPERATION
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.
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.
Flip the red latch up on the tool’s cuff to rotate the rescue tool.
Flip the latch down to lock the handle position.
To increase rotating handle tension,
tighten the tension screw shown above.

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
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
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

For exchanging spreader tips, See Section 8.1 on page 14.
WARNING
When
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
When
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.

7.4 TELESCOPING RAM OPERATION
The telescoping ram has two stages that extend out in sequence. The first stage has a higher force than the second stage due to its
larger diameter.
Figure 7.4A
Table 7.4B
WARNING
Crushing from falling or rolling loads may result in injury or death. To reduce risk, observe the
following:
• Identify the crush zone. These are areas under the load and around the load with risk of
crushing from a falling or rolling load.
• Position the ram base securely against a support surface. Excess space may be taken up using
cribbing.
• Extend the lifting head to the object being displaced.
• Ensure nearby people are clear of the crush zone before lifting or retracting.
• Displace the object only as far as needed.
• Stop to stabilize the load in increments as the load is lifted or lowered.
NOTICE
The telescoping ram is used in pushing and lifting objects with pistons extending. The load is held
when the control valve actuator is in OFF (neutral) position. The ram is NOT to be used for pulling
tension loads with pistons retracting.

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.
Figure 8.1
8.2 CHAIN USE
Chain kits are available for spreaders.
Setup and operation of the chain kit:
• Secure the chains around the load, latching the grab hooks

Tools with moving blades have a guard over the moving parts. The guard is
secured with screws which can be removed to clear debris during
maintenance. Replace guards after maintenance.
10.0 MAINTENANCE
PRIODIC MAINTENANCE SCHEDULE
Table 10.0
10.1 ROUTINE MAINTENANCE
10.1.1 CHECK THE BLADES
The use of damaged blades decreases the cutting efficiency of the tool and can overheat the tool.
Replace the blades when they become worn, cracked, or gouged. (Consult AMKUS Rescue Systems)
Check the torque on the cutter & combination tool pivot bolt monthly. Proper pivot bolt torque is 140 ft-lbs (190 N-m).
10.1.2 HYDRAULIC MAINTENANCE
Inspect the tool and hydraulic hoses for leaks. Inspect the hydraulic hoses and couplers for debris, damage, and proper operation.
Replace any damaged components. Remove the tool from use if damaged. Contact your local dealer or amkus.com for repairs.
10.1.3 LUBRICATION
Cutter blades, combi blades, spreader arms, links, and pins are lubricated with white lithium grease. Annual re-lubrication per Service
Procedures is recommended for average service conditions. More frequent lubrication may be required for severe or frequent usage
conditions.
10.1.4 HANDLE LIGHT BATTERY REPLACEMENT
To replace the batteries:
1. Remove the lid screws with a 3 mm hex key.
2. Remove and replace the 2 AA batteries in the battery holder.
3. Use the hex key to tighten the lid screws back into position.
