1.5.4. Handling the Wheelchair
● Modifying the unit or its mounting may adversely affect its performance and safety. Never
make any modifications.

● If the wheelchair has parts that are foldable or detachable, do not operate the wheelchair
with those parts folded or removed.
● When lifting the wheelchair, do not hold movable parts.
● Do not operate with any heavy baggage hanging
over the backrest, or with any heavy objects in
the compartment. The wheelchair could easily fall
backward on an inclined slope, and may cause
you or people around you to get injured.
● The wheelchair may tip over if it is operated with the anti-tip devices removed, folded, or
with the safety wheels facing upwards. Be sure to set the anti-tip devices correctly and op-
erate the wheelchair with the safety wheels in the correct position.
● Do not connect any electric instruments to the plug on the joystick. This plug is to connect
a PC for the Smart Tune software. Plugging other electric instruments like audio microphone
or earphones may cause unit trouble.
About the Smart Tune software, refer to "11. Wheelchair Disassembly and Adjustment".
● Do not hang anything on the joystick on the
controller. It may get in the way of your operation,
or the weight of the object may prevent the joystick
from returning to its original position, even after
your hand has released it.
In addition, if you put a rubber band around the
joystick, it may get jammed inside the controller,
causing the joystick to not return to its original
position.
In either case, there is a risk of the wheelchair not
stopping.
● Do not receive microwave thermotherapy while
seated in the wheelchair.
The microwaves may result in drive unit malfunc-
tions, accidental operations and heated metal
parts causing burns.
Switch off the power to motorized wheelchairs
and place them away from microwave thermother-
apy equipment.
