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.
2.2 Leaning
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 Negotiating Inclines
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)

2
2.3.3 Avoid stopping on an incline; it can potentially cause you to lose
control of the chair.
2.4 Kerb(Curbs)
2.4.1 Avoid hard impacts when descending a curb. A hard impact could
adversely affect the chair.
2.4.2 Never try to scale or descend curbs that exceed a normal height
(30-50mm).
2.4.3 Always be careful when climbing curbs and never move up or down
a curb in reverse without an assistant.
2.5 Stairs
2.5.1 Always use two or more assistants. Tilt the wheelchair to its point of
equilibrium. One assistant (in the back) holds the wheelchair up against
the first step, gripping the handles firmly to lift. The second assistant,
holding firmly a fixed part of the front frame, lifts the wheelchair above
the stairs and holds it while the first attendant places one foot on the
following step and repeat the operation. (See Figure 2.1)
2.5.2 Never go down steps forwards.
2.5.3 Never use an escalator for transport, use an elevator.
Figure 2.1 Figure 2.2

of the chair.

2.6.3 Use caution to assure your clothing doesn't get tangled with the
wheels.
2.6.4 When the user is operating the wheelchair using the push rims,
please push the wheelchair gently. DO NOT apply a sudden huge force on
the push rims. It could cause the chair to tip over. Please refer to the
figure below for the best grip points for using the push rims.
2.7 Upholstery
2.7.1 When cleaning the upholstery, use warm water and a mild soap.
2.7.2 Upholstery cleaner/foam can also be used, but avoid other cleaning
solvents.

3. OPERATION
CAUTION:
● If you find anything abnormal, stop using the wheelchair
immediately and visit a KARMA wheelchair dealer for inspection and
maintenance
3.1 Unfolding
3.1.1 Unfold the push handle. (See Figure 4.1)
3.1.2 Holding the armrests, pull outwards. (See Figure 4.2)
3.1.3 Pointing your fingers inward with the palm of your hand on the
frame, push down until the seat is fully lowered. Make sure the frame is
firmly seated in its holder. (See Figure 4.3)
3.1.4 Swing the footplates down. (See Figure 4.4)
Figure 4.1 Figure 4.2 Figure 4.3 Figure 4.4
CAUTION:
● When completing step 2, never put your fingers
around the sides or under the chair as they can be
trapped between the seat and the frame. (See Figure
4.5) Figure 4.5
3.2 Folding
3.2.1 Flip up the footplates. (See Figure 4.6)
3.2.2 Pull up on the seat upholstery by holding it in the center of its front
and back edge. (See Figure 4.7)
3.2.3 Press the two release levers on the backrest frame (push handle
tubes) to fold the backrest down for compact storage and easy transport
(for SM-150.3). (See Figure 4.8)

Figure 4.6 Figure 4.7 Figure 4.8
3.3 Rear Wheel Attachment
3.3.1 Pick up the wheel: Hold the center of the rear wheel by grasping two
adjacent spokes with four fingers of one hand, use the thumb to depress
and keep depressed the quick-release. Take the quick-release axle and
depress the button in its center. This retracts the bearings at the opposite
end of the axle. This will allow you to push the axle through the center of
the hub of the wheel. Your wheels are now ready to be assembled to the
frame of your wheelchair.
3.3.2 First ensure that the brake is in the OFF position. Take up the
assembled wheel and axle and depress the button in the center of the
axle, as above. This retracts the ball bearings that will allow you to push
the axle into the wheel bracket that is located on the lower rear frame of
the wheelchair. When you remove your thumb from the button on the
axle, the ball bearings should be visible protruding from the axle at the
back of the wheel bracket. This will secure the wheel safely in the frame.
(See Figure 4.10)
