It is the operator’s responsibility to verify that the shore power receptacle is of
the same type and voltage as the connection that is supplied by Oshkosh
Specialty Vehicles. Failure to do this can result in injury or death to the
operator of the mobile unit as well as irreparable damage to the mobile unit.
Make sure that all electrical parts are serviced only by a certified electrician or
qualified personnel. Dangerous voltages are present which could result in
injury or death.
Always make sure that eyes are protected while servicing the unit. Wear safety
goggles when prying, drilling, grinding, or working with batteries. Wear safety
goggles over regular prescription glasses unless the lenses are made of
hardened glass and can serve as safety goggles.
Be certain to disconnect the power before working on any of the electrical
systems.
When servicing the unit be certain that a first aid kit and fire extinguisher are
within reach at all times.
This safety section contains important information in regards to general safety guidelines that
should be followed. Before attempting to service the mobile unit, read this safety section as well as
all other safety sections found in applicable manufacturers’ manuals in the component literature
binder.
2.1 General Safety Precautions
1. Make sure the work area is well ventilated.
2. Disconnect the electrical power to prevent the possibility of electrical shock when servicing
all electrical equipment.
3. Follow all manufacturers’ directions and request material data sheets where applicable.
4. Always keep tools clean and free of grease.
5. Do not stand on chairs inside of the mobile unit under any circumstances.
6. Follow all safety precautions found in the documentation package that is included with the
mobile unit.

express consent.
2.2 Magnet Safety
A magnetic shielding system has been installed on each sidewall opposite of the magnet, and on
the rear wall of the mobile unit. The magnetic shielding system is extremely effective, and designed
to meet or exceed the Mobile MRI site plan requirements of the medical equipment manufacturer.
This system is proprietary.
1. All personnel with pacemakers, metal implants and neurostimulators should avoid entering
the exclusion zone of the magnetic field. The medical equipment manufacturer defines the
exclusion zone of the magnetic field.
2. Do not bring ferrous materials into the exclusion zone. These items may become
projectiles and cause serious injury, and / or property damage.
3. Watches can be damaged and credit cards can be erased if brought into the exclusion
zone.
2.3 Chemical Safety
1. When working in the presence of liquid helium, make sure the work area is well ventilated.
2. Inhalation of helium or nitrogen can cause rapid suffocation. If any personnel inhale gas,
quickly move them to fresh air and seek medical attention at once.
3. The gases used in mobile MRI units to cool the magnet can cause severe frostbite. If
frostbite occurs, seek medical attention at once.
4. Liquid or gas can freeze air inside of vent lines. Check periodically to be certain that the
vent screen is open.
2.4 Electrical Safety
Use and follow the appropriate Lockout/Tagout procedures as required by
OSHA Standard 1910.147 when performing maintenance or servicing any
electrical, hydraulic or pneumatic systems. See Appendix E for Lockout/Tagout
procedures.
Before connecting or disconnecting from shore power, it is imperative that the
shore power connections be moved to the “OFF” position. Failure to do this
can result in injury or death to the operator of the mobile unit.
It is the operator’s responsibility to verify that the shore power receptacle is of
the same type and voltage as the connection that is supplied by Oshkosh
Specialty Vehicles. Failure to do this can result in injury or death to the
operator of the mobile unit as well as irreparable damage to the mobile unit.
Always inspect the power cable, connectors, and fasteners prior to usage. If
during inspection, it is suspected that either internal or external damage has
occurred, have a certified electrician inspect and repair the damage before
using.
When working with the electrical system for the mobile unit. Follow the warnings and cautions listed
above.

2.5 Transportation Safety
Check the tires before every trip for wear, cuts breaks, cracks, defects,
objects caught or penetrating the tire carcass and for proper inflation. Check
tire pressure when the tires are cool and maintain the pressure molded into
the sidewall. Do not operate a trailer with tires that have the internal
reinforcing wires or belt showing or less than 2/32” tread depth, when
measured at a major tread groove. See 49 CFR Sec. 570.9(a).Replacement
tires MUST BE Radial.
1. Walk around the unit to make certain that all doors are closed and locked and that the
Platform Lift is seated in the retaining cradles with the transport pins installed.
2. If any of the warning lights are illuminated, do not move the mobile unit.
3. Before moving the mobile unit, verify that all marker and running lights are working
properly.
4. Consult with the local DMV to determine if there are any travel restrictions or routes.
Due care must be exercised to avoid severe operating environments
that endanger the system equipment. Failure to do so could result in
invalidating the Siemens Magnet Technology warranty.
Disobeying posted speed limits, driving dangerously, driving while
under the influence of alcohol or drugs, driving without a valid
operators license, or insurance or driving without due care or any
illegal action by the driver may result in invalidating the Siemens
Magnet Technology warranty.
Due care must be exercised to use the lowest speeds possible when
docking and undocking the trailer. Failure to do so could result in
invalidating the Siemens Magnet Technology warranty.
The owner/operator must notify Siemens Magnet Technology within
one (1) day of any instance that causes the shock logger alarm to
sound. Failure to do so could result in invalidating the Siemens Magnet
Technology warranty. Contact the local Siemens Medical Systems
Representative.

Section 3: Mobile Unit Overview
The components of the mobile unit have been divided into alphabetical order. With each
component a picture and description will be found to better illustrate the components of the mobile
unit. Additional components of the mobile unit can be found within the remaining chapters.
3.1 Air Ride Control Valves
The air ride control valves must be in the normal ride position before the
mobile unit can be transported. If the air ride control valves are not in the
normal ride position, irreparable damage may occur to the mobile unit.
The air ride control valves adjust the rear air suspension bags. When the mobile unit is being
transported, the air ride control valves must be in the normal ride position.
