Important Safety Instructions
Safety
It is the responsibility of the user to insure that appropriate
protective clothing and equipment are used to provide
protection from those hazards to which personnel are
exposed or could be exposed while working with this
product. Always wear appropriate apparel!
AMKUS equipment is manufactured with superior
craftsmanship and quality that is backed by a factory
warranty. AMKUS cannot control how other manufacturers
of rescue tools rate, test and warranty their equipment.
Therefore, we do not recommend that tools other than
AMKUS be connected to our equipment. Mixing AMKUS
equipment with another manufacturer’s equipment may
cause operational problems, equipment failure or warranty
claims to be denied.
Use only AMKUS supplied
mineral base hydraulic
fluid in all AMKUS equipment.
Training
This product is designed to be used by emergency services
personnel to facilitate the extrication of victims from
entrapment. Its use should be limited to trained personnel
only. All personnel using this equipment are assumed to
have completed a course of instruction that is acknowledged
as being educationally sound by the local authority having
jurisdiction over such training. This document contains
basic operating and maintenance instructions only.
Getting Started
1. Connect the tool connection hoses to the hose lines from
the AMKUS hydraulic power unit. 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 ¼ turn so that the pin
no longer lines up with the notch. Pull on the couplings to
check that they are securely connected.
2. Check the engine oil, engine fuel and hydraulic fluid
levels. Add as appropriate.
Read and understand the
engine owner’s manual
before operating the engine! Failure to do so
could result in personal injury or equipment
damage!
Set-Up Procedures
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, please review
the following instructions carefully.
1. Remove equipment from the packing cartons and
carefully inspect for damage. Damage that occurs during
shipment should be reported immediately to the carrier.
2. The Briggs and Stratton®engine that powers your unit is
shipped without engine oil. Fill the engine crankcase with
the proper oil as specified in the engine owner’s manual.
3. Next, remove the hydraulic fluid reservoir fill plug/vent
cap. Fill the hydraulic fluid reservoir with approximately 2.0
gallons U.S. (7.6 liters) of AMKUS mineral base hydraulic
fluid. The fluid should reach a level that fills approximately
1/2of the sight gauge window. Replace the fill plug/vent cap.
4. Following the instructions in the engine owner’s
manual, fill the engine fuel tank with the specified fuel.
Avoid getting dirt or water in the fuel tank. Never use stale
or contaminated gasoline or an oil/gasoline
mixture.
5. This power unit may be supplied either with hydraulic
hoses attached (pump hoses) or with couplings that require
extension hoses. If your unit is equipped with couplings,
attach the extension hoses to the couplings on the power
unit. In either case, connect the male and female couplings
on each of the hydraulic hose line sets, creating a loop.
6. Follow the operating instructions in the engine owner’s
manual for starting the engine. Then operate the engine at
full speed.
7. To purge air from the hydraulic hoses, charge each
hose line by moving the knob on the corresponding selector
valve to the pressure position (in line with the selected hose
line) and allow the fluid to circulate through each hose line
for at least one minute. Move each selector valve back to
the neutral position.
8. Check the level of the hydraulic fluid in the sight gauge.
Add more fluid if necessary. DO NOT OVERFILL.
9. Uncouple the male and female couplings on each
hydraulic hose line set to open the loop that was created
earlier. The power unit is now ready to use.

Routine Maintenance for Gasoline Engine
Follow the maintenance guidelines in the engine owner’s
manual.
Routine Maintenance for Hydraulic Pump
Normally, you will have a maintenance agreement for
your system with your local dealer. However, if you have
decided to service the equipment yourself, please review
the following instructions carefully.
Change hydraulic fluid after each 20 hours of tool operation
(approximately every 2 years). If you suspect your
hydraulic fluid has been contaminated in any way, contact
your local dealer or AMKUS, Inc.
To change the hydraulic fluid, remove the hydraulic fluid
reservoir fill plug/vent cap. Place the unit over a drain pan;
unscrew and remove the drain plug. Be careful not to lose
it! Allow the hydraulic fluid to drain. Clean and replace
the drain plug. Fill the hydraulic fluid reservoir with new
AMKUS mineral base hydraulic fluid. Replace the fill plug/
vent cap.
Connect the male and female couplings on each of the
hydraulic hose line sets, creating a loop. Follow the
operating instructions in the engine owner’s manual for
starting the engine. Then operate the engine at full speed.
To purge air from the hydraulic hoses, charge each hose
line by moving the knob on the corresponding selector
valve to the pressure position (in line with the selected hose
line) and allow the fluid to circulate through each hose line
for at least one minute. Move each selector valve back to
the neutral position. Check the level of the hydraulic fluid
in the sight gauge. Add more fluid if necessary. DO NOT
OVERFILL.
Uncouple the male and female couplings on each hydraulic
hose line set to open the loop that was created earlier.
Check the pressure output of the power unit at each hose
line by connecting a pressure gauge to the pressure line
(the male coupling). Move the selector valve to charge
the line to which the gauge is connected. The nominal
pressure of the system is 10,500 psi. The pressure reading
you receive should be between 10,000 psi and 11,000
psi. If you have a reading outside of that range, contact
your local dealer or AMKUS, Inc. DO NOT ATTEMPT TO
ADJUST THE PRESSURE RELIEF SETTING!
Routine Maintenance for Hoses
After each use, hoses should be wiped clean with a light
cleaning solvent such as Simple Green®. Inspect hoses
for damage to the rubber outer cover. Damage which
exposes the wire braided reinforcement subjects the wire
to corrosion and may weaken the hose. Damaged hoses
should be replaced.

Operating Instructions
Following the instructions in the engine owner’s manual,
start the engine. Operate the engine at full speed for
maximum rescue tool speed and performance. Use the idle
position only when the rescue tools are not being operated.
The GB2S-XLO is a simultaneous operation power unit.
This means that two tools can be connected simultaneously
and operated either independently or simultaneously.
In order to operate a tool that is connected to the power
unit, the appropriate hose line must be charged by moving
the knob on the corresponding selector valve to the
pressure position (in line with the hose line to which the tool
is connected). The selected tool is now operational.
To stop the flow of hydraulic fluid to each hose line, move
the knob of the corresponding selector valve to the neutral
position (perpendicular to the hose line). The selector valve
should be in the neutral position when you are finished
with an operation or anytime you wish to stop the flow of
hydraulic fluid.
Please note that the minimum safe bend radius of the
hoses is 4 inches (101.6 mm).
When you have finished operations, follow the instructions
in the engine owner’s manual to stop the engine.

Maintenance Records
It is the responsibility of the user to keep maintenance
records for each component of the rescue system.
Maintenance shall be performed in accordance with the
recommendations as outlined in this manual.
Routine Maintenance for Couplings
Couplings should be kept free of dirt and contaminants.
They may be most easily cleaned by immersing in, or
scrubbing with, a petroleum based solvent such as SAFE-
SOL® 140. Couplings should then be lubricated with a
non-water based lubricant such as WD-40®. The rubber
dust caps which are provided with the tools should also be
cleaned periodically. Be aware that while the couplings
may be clean, the dust caps will accumulate dirt during use.
Do not cover a clean coupling with a dirty dust cap.
