Transit Checklist 10.0
CAUT ION
In the event that the chair is ever in an vehicular collision, check all hardware
thoroughly for damage. If there are any signs of damage, have a qualified tech
inspect and replace the damaged components or send to Stealth Products for a
complete overhaul to ensure future safety.
Before Transit: 10.1
Prior to transporting:
 Always double check the e-downs and hardware.
 On e-downs and restraints, look for tears or worn webbing straps.
 Look for damaged hooks or loose e down hardware.
 On the seang system, check for loose screws aaching the hardware to the seat. These
should be snug and not over ghtened.
 The knob hardware should be snug and if transit pins are available, they should be
inserted. These pins keep the chair aached to the frame even in the event that a knob
were to come loose and come o the chair.
 If there is a tray or any items that can become airborne or cause bodily harm in the event
of a crash, relocate and secure them.
Pre-Transit 10.2
 The chair is in a forward facing posion.
 All hardware is checked for loose screws or damaged components.
 Check that all e-down straps are secure and restraints are not twisted.
 Any loose objects are removed and placed in secure areas.
 Seat belt restraints that are compliant with ANSI/RESNA WC/Vol. 4, Secon 19/ISO
7176-19 are ulized.
NOTI CE
Replace as necessary and never use torn straps.

funcon of every item.
Have the user test the swing away system:
 Is the hardware in the proper posion for the client?
 Can the user safely operate the wheelchair with minimal eort?
 Is the placement of the hardware in an opmal posion for the user?
If needed, adjust the TWBM480 to the proper position.
Explain to the customer possible problems and how to address them.

the installation instructions in this manual.
