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 (30-50mm).
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 places one foot on the following step and repeat the operation
(See Figure2.6)
Never go down steps forwards.
Never use an escalator for transport, use an elevator.

Figure 2.6 Figure 2.7
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
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
Please purchase anti-tippers and always use them to avoid personal injury. The
distance between anti-tipper and wheels is at least 5cm; the height to floor doesn’t
be over 5cm. (See Figure2.7)
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.

4.1.3.2 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 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.

4.1.3.2.3 Important DO’s and DON'T’s
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 ccupied even when
using anti-tippers.
4.1.3.3 Footrest
Footrests can rotate in or out, which makes transferring in tight spaces easier and
swinging both footrests inward makes it easier to work at a desk. (See Figures
4.17 and 4.18)
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 4.19)
Figure 4.17 Figure 4.18 Figure 4.19 Figure 4.20
SUGGESTION:
Make sure that the footplate height is adjusted properly according to the
users calf length to reduce pressure on the body.
The footrest height must be more than 5cm. (See Figure 4.20)

seat height or changing different wheel sizes, do make sure that the caster angle is
vertical to the ground. (See Figure 4.24)
CAUTION:
We recommend that you contact your therapist or Karma’
s authorized dealer
in case you need to change the angle of caster
. Otherwise you might
damage your wheelchair or injury the user.
