Clear Zones
Clear (or clear-space) zones indicate the safe areas around the front and back of a secured
wheelchair. The recommended front clear zone (FCZ) is 26” (measured from the front of
the occupant’s head) if the occupant is restrained by both pelvic and shoulder belts and
37” inches if only a pelvic restraint is used (Figure 34 and Figure 35). It is understood that
the frontal (or forward) clearance zone (FCZ) may not be achievable for wheelchair-seated
drivers. The rear clear zone is 16” measured from the back of the occupant’s head.

Service
•
The Model M contains no user-serviceable parts. Do not attempt to replace or repair
any parts (including the batteries) on your own. Doing so may result in damage
and/or injury. Service should only be done by a WHILL-authorized service
representative.
•
Do not spray water to clean off the Model M. Moisture may damage Model M
components and make it inoperable.
•
Do not attempt to adjust or modify the Model M. Doing so may damage the Model
M. Adjusting or modifying the Model M may also make it less stable or impact its
performance, resulting in injury if the chair tips over or is not controllable.
Transportation
If your device is not equipped with securement points for transportation:
•
Do not let anyone sit in the wheelchair while in a moving vehicle.
•
Transfer to the vehicle seat and use the vehicle-installed occupant restraint system.
•
Make sure the brake releases are locked and secure the wheelchair so that it cannot
roll or shift.
•
Do not transport the wheelchair in the front seat of a vehicle. If it moves or shifts it
can interfere with the driver.
•
Any wheelchair that has been involved in a motor vehicle accident should not be
used until inspected and tested by WHILL authorized service personnel. The
structure or the wheelchair could be compromised or components broken that could
make the wheelchair unsafe to operate or could otherwise injure you.
If your device has securement points:
•
Please contact WHILL customer support with questions about using the wheelchair
as a seat in a motor vehicle.
•
The wheelchair must only be transported in a vehicle that is approved for such
purposes.
•
Only forward-facing use of the wheelchair in a motor vehicle is allowed.
•
Only use the wheelchair in a motor vehicle as described in these instructions.
•
Dynamic testing was conducted in a forward-facing wheelchair with a 172 lb crash
test dummy restrained by both pelvic and shoulder belts. Both pelvic and shoulder
belts should be used to reduce the possibility of head and chest impacts with vehicle
components.
•
Do not make any alterations to the wheelchair frame components or parts as these
can compromise the device’s transportability.
•
Make sure the brake releases are locked and secure the wheelchair so that it cannot
roll or shift
