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 2.1)
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 Curbs
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 curb. A hard impact could adversely affect the chair.
Never try to scale or descend curbs that exceed a normal height. (30-50cm)
Always be careful when climbing curbs and never move up or down a curb in reverse without an assistant.
2.5 Stairs
Always use two or more assistants. Tilt the wheelchair to its point of equilibrium. One assistant (at 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 place one foot on the following step and repeat the operation. (See
below figure)
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)

3
2.7 General
Always make sure BOTH brakes are applied before getting in or out of the chair.
Never stand on the footplates when getting in or out of the chair.
Never carry more than one passenger. Karma wheelchairs are limited to one user.
Use caution to assure your clothing doesn't get tangled with the wheels.
2.8 Transport
Do not use other transportation to pull the wheelchair.
Do not get transported on any vehicle while seated in your wheelchair. Karma doesn't approve of any tie-down systems. Please
transfer into seating approved by the automotive (or other) industry and wear a safety belt.
2.9 Upholstery
When cleaning the upholstery, use warm water and a mild soap.
Upholstery cleaner/foam can also be used, but avoid other cleaning solvents.
2.10 Anti-tippers
Anti-tipper must be installed under all conditions, especially when the backrest is reclined. (See below figure)
2.11 Maximum User Weight Limit
Refer to "Max. User Weight" in section 8. SPECIFICATIONS. Loads exceeding
maximum capacity can damage your wheelchair and cause malfunctions yielding a
safety hazard. The warranty does not cover damage caused by improper
operation of the wheelchair.
2.12 Avoid General Misuse
Please note that our "Owner's Manual" contains a number of cautions -- any vehicle can cause injury if misused -- use within our
guidelines and with reasonable care and your safety will be increased. Your wheelchair will give years of safe use if used sensibly
and carefully. Be aware that careless use endangers your own safety as well as that of others. ALWAYS follow the Highway
Code when outdoors and the guidelines written in this manual.

4.2.6 Rear Wheel
Your wheelchair may be supplied with quick-release wheels (option) If this is the
case, please follow the instructions below.
4.2.6.1 Rear Wheel Removal
Support the weight of the chair with one hand by holding the push handle.
Press the hub button and hold down the quick-release mechanism.

4.2.6.2 Rear Wheel Attachment
First ensure that the brake is at the OFF position. Take up the assembled wheel and axle and press the button in the centre of the
axle. This action 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 on the frame. (See Figure 4.40)
CAUTION:
You should make sure that the axle is entirely mounted in the wheelchair bracket and that the ball bearings are fully open and have
positively attached the wheel on 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, technician, or therapist.
