5.0 ROUTINE MAINTENANCE FOR GASOLINE ENGINE
Follow the maintenance guidelines in the engine owner’s manual.
5.1 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 fl uid after each 20 hours of tool operation (approximately every 2 years). If you suspect your hydraulic fl uid has
been contaminated in any way, contact your local dealer or AMKUS, Inc.
To change the hydraulic fl uid, remove the hydraulic fl uid reservoir fi ll 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 fl uid to drain. Clean and replace the drain plug. Fill the hydraulic
fl uid reservoir with new AMKUS mineral base hydraulic fl uid. Replace the fi ll 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 fl uid 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 fl uid in the sight gauge. Add more fl uid 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!
5.2 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.
5.3 ROUTINE MAINTENANCE FOR COUPLINGS
WARNING Damaged couplings should be replaced immediately. Damaged damaged could cause hydraulic
fl uid to escape under high pressure. Contact with escaping hydraulic fl uid under pressure could
result in serious injury or death. Loss of hydraulic pressure prevents the rescue tool from operating
properly and may result in serious injury or death.
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.
5.4 MAINTENANCE RECORDS
It is a user’s responsibility 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.
5.5 GENERAL MAINTENANCE AND STORAGE
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
acknowledged as being educationally sound by the local authority having jurisdiction over such training. This document contains

6.0 SET-UP PROCEDURE
AMKUS equipment is manufactured with superior craftsmanship and quality backed by a factory warranty.
NOTICE Only use AMKUS tools with AMKUS equipment. Mixing AMKUS tools with another manufacturer’s
equipment may cause operational problems, equipment failure, or denial of warranty claims.
NOTICE Only use AMKUS MV1 hydraulic fl uid in AMKUS equipment. Using another manufacturer’s
hydraulic fl uid in AMKUS equipment may cause operational problems, equipment failure, or
denial of warranty claims.
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 model G100 Honda® engine that powers your unit is shipped without engine oil. Fill the engine crankcase with he proper oil
as specifi ed in the engine owner’s manual.
3. Next, remove the hydraulic fl uid reservoir fi ll plug/vent cap. Fill the hydraulic fl uid reservoir with approximately 2.0 gallons U.S. (7.6
liters) of AMKUS mineral base hydraulic fl uid. The fl uid should reach a level that fi lls approximately 1/2 of the sight gauge window.
Replace the fi ll plug/vent cap..
4. Following the instructions in the engine owner’s manual, fi ll the engine fuel tank with the specifi ed 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 fl uid 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 fl uid in the sight gauge. Add more fl uid 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.
7.0 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 fi ts 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 fl uid levels. Add as appropriate.

8.0 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 GH2S2-XLNT 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 fl ow of hydraulic fl uid 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 fi nished with an operation or
anytime you wish to stop the fl ow of hydraulic fl uid.
When you have fi nished operations, follow the instructions in the engine owner’s manual to stop the engine.
NOTICE The minimum safe bend radius of the hoses is 4 inches (101.6 mm).
When you have fi nished operations, follow the instructions in the engine owner’s manual to stop the engine.
