1. PREFACE
Please carefully read this owner's manual before using the wheelchair. Improper use of
the wheelchair could result in harm or injury.
1.1 This owner's manual includes operation instructions for the aspects of the
wheelchair, unfolding/folding instructions and instructions on how to deal with
possible accidents.
1.2 As designs change, some illustrations and pictures in this owner's manual may not
correspond to the wheelchair that you purchased. We reserve the right to make
design modifications without further notice.
1.3 Whenever possible, please get help from an assistant/attendant while going on
inclines, curbs or stairs.
2. SAFETY
2.1 Doorways
The safest way to operate the chair is on level floors that are free of obstacles.
Whenever possible use a ramp to enter or exit a facility. Keeping your hands on the
push rims will allow you to maintain maximum balance. Do not try to force yourself
over an obstruction by propulsion and never use the sides of a doorway to pull
yourself through a passageway.

Do not lean over the side of your wheelchair since such an action may cause you to
lose balance and fall. (See Figure 2.3)

2.3.1 Never turn on a hill due to the danger of tipping.
2.3.2 When assisting, go straight up a slope. If user needs to go down midway, walk
backwards until user is on level ground. (See Figures 2.4 and 2.5)
