WARNING

The wheelchairs equipped with the JWX-1 are built to be lighter compared to other heavier
electric wheelchairs that use a general lead battery. For this reason, when a person sits in it,
the overall center of gravity shifts higher. Therefore, caution is necessary when traveling on a
slope.

L Do not use the wheelchair on a slope steeper

than 6 degree (10% grade). It may tip over or
the brake may become ineffective.

L When going up/down a particular slope for the

first time, have an assistant accompany you to
ensure safety.

L In areas with an incline, do not switch the

clutch levers to the manual position. The
wheelchair may start moving unexpectedly,
and may collide or tip over.

WARNING

L If it is raining or snowing, do not operate the

wheelchair outdoors. Automobiles and other ve­hicles may collide into you if they cannot recog­nize you. If it starts to rain or snow while you are
outdoors, move indoors as soon as possible.

WARNING

L Do not abruptly turn on a downhill slope. In

addition, do not traverse horizontally or diago

­nally across a steep slope. You could easily
lose balance and tip over.

L In the areas where the wheelchair leans

sharply to the left or right, the wheelchair may
tip over sideway. Have an assistant accom

-

pany you.

L When descending down a slope with the as-

sistant operations, descend in reverse. If the
assistant moves the wheelchair forward when
descending, the passenger may plunge for

-

ward and fall off the wheelchair.

WARNING

The wheelchairs equipped with the JWX-1 are built to be lighter compared to other electric
wheelchairs that use a general lead battery. For this reason, when a person sits in it, the overall
center of gravity shifts higher. Therefore, caution is necessary when traveling on a curb.

L When traveling in power drive mode, the

wheelchair can clear level differences of up to
25 mm (1 inch). Any greater level differences
should be cleared by an assistant by manual
push operation.

1.5.8. Going Up/Down Curbs

1

15

WARNING

L When going up/down a curb for the first time,

have an assistant accompany you instead of
traveling alone.

L When traveling over a curb, be careful not to lose your balance.

L When traveling over a curb, proceed at a right

angle to the curb. Do not traverse the curb
diagonally.

L Because the front casters are small, they are

able to travel over only small curbs. There

­fore, caution is necessary when traveling over
curbs in power drive mode.

L When traveling between a sidewalk and a

road, be careful of curbs.

L To travel over a curb or other obstacles with

the assistant operations, turn off the assistant
controller and go over it manually. If the as

­sistant goes over a curb or other obstacles in
power drive mode, the assistant could easily
lose balance and the passenger or assistant
could get injured if the wheelchair tips over.
