to the power drive position.

11. Using the Wheelchair more Comfortably

The JWX-1 has a variety of features to improve its controllability. Use these features according to
your purposes. For information on the wheelchair frame to which JWX-1 is attached, see the owner’s
manual from the frame manufacturer.

11.1. Removing and Installing the Unit

The power units of the JWX-1 can be removed from the frame when replacing the current wheels
with manual wheels or when transporting the wheelchair.

(1) Removing the power units from the frame

Turn off the power and remove the battery. Put the protective cap on the re-

moved battery.

Disconnect the connectors “a” of the cables from

the left and right power units. To disconnect a

connector, turn the outer ring on the connector

counterclockwise until it stops, and then pull out

the connector.

Place the wheelchair so that it will not become

unstable when the power units are removed. (For

example, as shown in the figure.)

Release the parking brakes.
