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 your to
lose balance and fall. (See Figure 2.1)
2.3 Navigating Inclines
Never turn on a hill due to the danger of tipping.
When assisting, go straight up a slope. If user needs to go down midway, walk
backwards until user is on level ground. (See Figures 2.2 and 2.3)
Avoid stopping on an incline; it can potentially cause you to lose control of the chair.
Do not use the brakes to slow down or stop the wheelchair; this could cause it to seize
up, causing you to lose control or fall out of the chair.
Whenever possible, utilize help from an assistant/attendant while navigating inclines.
2.4 Kerbs
Whenever possible get help from an assistant/attendant (if you have assistance make
sure that your chair is equipped with push handles).
Avoid hard impacts when descending a kerbs. A hard impact could adversely affect the
chair.
Never try to scale or descend kerbs that exceed a normal height.(30-50mm)
Always be careful when climbing kerbs and never move up or down a kerbs in reverse
without an assistant.
2.5 Stairs
Always use two or more assistants.
Never go down steps forwards.
Never use an escalator for transport, use an elevator.
2.6 Streets
Always use extreme caution when crossing streets. Reflective tape on the chair and/or
your clothing will make you more visible to drivers.
Avoid potholes and rough terrain that might cause the casters to become stuck. (See
Figure 2.4)
2.7 General

4.1.3 Adjustments
4.1.3.1 Armrest
Armrest flips back by pressing the release lever located at the front base of the
armrest. After you press the release lever, you can lift and rotate the armrest
backwards. (See Figures 4.13 and 4.14)
The height adjustable armrest feature is optional. If your model has it, simply loosen
and remove the knob bolt, then adjust the armrest to the desired height and finally
reattach the knob bolt.
Figure 4.13 Figure 4.14
4.1.3.2 Rear Wheel
Your wheelchair may be supplied with quick-release wheels. If so, please follow the
instructions below.
4.1.3.2.1 Rear Wheel Removal
Support the weight of the chair with one hand by holding the push handle.
Depress the hub cover and hold down the quick-release mechanism.
Remove the wheel. (See Figure 4.15)
4.1.3.2.2 Rear Wheel Attachment
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.
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

11
bracket. This will secure the wheel safely in the frame. (See Figure 4.16)
CAUTION:
You must make sure that the axle is fully located in the wheelchair bracket and that the
ball bearings are fully open and have positively attached the wheel in the frame.
The rear wheel can be mounted at different positions on the frame to alter the seat
height and overall stability of the chair. Changing the wheel position should be carried
out by your approved repairer or therapist.
Figure 4.15 Figure 4.16
4.1.3.2.3 Important DO's and DON'Ts
Do: Keep axles clean and lubricated with light oil or maintenance spray.
Do: Maintain correct tire pressure if using pneumatic tires.
Do not: Try to remove the wheels while the wheelchair is occupied even when using
anti-tippers.
4.1.3.3 Footrest
Footrests can rotate out and are detachable, which makes transferring in tight
spaces easier and makes it easier to work at a desk. (See Figures 4.17)
4.1.3.4 Footplate Height
To adjust footplate height use the Karma tool provided to loosen the bolt at the side of
the footrest arm.
Adjust to required height and re-tighten the screw and make sure the footplate is firm.
Then tighten the nut as a locknut from outside. (See Figure 4.18)

12
Figure 4.17 Figure 4.18 Figure 4.19
SUGGESTION:
Make sure that the footplate height is adjusted properly according to the user's calf
length to reduce pressure on the body.
The footrest height must be more than 5 cm. (See Figure 4.19)
4.1.3.5 Seat Height
The following information is for your reference only. It will be utilized by your authorized
service agent and your therapist to customize the wheelchair to your specific body
dimensions.
