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.)
 Do not drive up to 7 degrees of incline to avoid danger. When navigating
inclines, don’t propel up to 3 degrees of incline.
 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.
 Always take care when climbing curbs or turning on slopes and never move
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 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.
 Please comply with traffic safety code.
 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.

personal injury. The distance between anti-tipper and wheels is at least 5cm;
the height to floor doesn’t be over 5cm.
2.11 Maximum User Weight Limit
Refer to "Max. Capacity" 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

4.2 Transferring In and Out
4.2.1 Transferring In





Engage both hand brakes.
Turn the footplates up and swing them to the side.
The user lowers his or her body into the seat using the armrests for support.
Turn the footplates back down, so that the user can place his feet on them.
Release both hand brakes.
CAUTION:
Always ensure that the front casters are in line with the rear wheels and
pointing forwards and that the back of the chair is secure either against a wall or
firmly held by an attendant.
4.2.2 Transferring Out
 Make sure that the chair is near your final destination.
 Back the chair sufficiently to ensure that the casters are pointing forward,
i.e. in line with the rear wheels and usually with the caster forks pointing
forward. Ensure that, where possible, the rear of the chair is against a wall
or, if not, it must be firmly held by an attendant.
 Engage both hand brakes.
 Turn the footplates up and swing them to the side.
 Slide forwards on the seat.
 Place one foot firmly on the ground with the knee at a right angle and the
other foot slightly apart and further back.
 Place your hands on the front of the armrests and moving your weight
forward, bring your head and shoulders up over your knees as you push
yourself up.
CAUTION:
 Never stand on the footplates when getting into (or out of) the chair. (See
Figure 4.22.)
 When getting in and out of the wheelchair please use the hand brakes. The
hand brake is the lever at the side of the wheelchair.
 Please ensure that neither the tread on your tires nor the brake block
becomes too worn. If pneumatic tires are fitted, please maintain at the
recommended tire pressure for the same reason.
 Please ensure that occupant's fingers do not get caught in the brake.
When transferring in and out of the chair, make sure that the brakes are applied
to prevent the chair from sliding away. Also see that the footplates are flipped
up for ease of entering or exiting. (See Figure 4.23)
4.3 General Use
4.3.1 Attendant Pushing and Self-propelled
 Do ensure that the brakes are always locked when the chair is not being
pushed. (See Figure 4.24.)
 Always make sure that both feet are safely on the footplates and that
clothing is safely tucked out of the way and so cannot get caught in the
wheels. (See Figure 4.25.)
 Always use both hands on the push handles to control the chair. (See
Figure 4.26.)
 Always avoid steep or uneven surfaces because the chair may tip over.
(See Figure 4.27.)
 Always avoid soft surfaces because the casters may get bogged down.
(See Figure 4.28.)
 Always be careful not to go too fast or turn too quickly and try to achieve a
smooth steady ride.
 Before crossing railroad tracks, please stop completely and look both ways.
 Cross the tracks perpendicular to avoid your wheels getting stuck.
 Do not move at full speed over the railroad tracks.
 Be careful going through a doorway that your hands and arms do not get
injured.
PLEASE keep in contact with the person in the chair. If you stop to look in shop
windows or talk to people, remember to turn the chair so that the person in the
chair does not have to turn.
WARNING:
NEVER lock the brakes too suddenly as this may tip the user out of the chair.
Figure 4.22
Figure 4.23
Figure 4.24
Figure 4.25
Figure 4.26
Figure 4.27
Figure 4.28
Figure 4.29
4.3.2 Tilting by the Attendant
 Make sure both the user's feet are on the footplates and will not slip off.
Make sure the handgrips are secure and cannot slip off.
 Release both brakes.
 Grasp both push handles firmly.
 Put your stronger foot on the relevant tipping lever at the back of the chair.
 Tell the person in the chair that you are about to tilt the chair backwards.
 Pull back with both hands and push down and forwards with the foot. This
will bring the chair onto the back wheels. (See Figure 4.29.)
CAUTION:
 When a chair is tilted to about 25 degrees it will balance on its rear wheels
and be easy to hold. If it is tilted further back it will be difficult to hold and the
person in the chair will feel unsafe.
 Lower the chair with your back straight, keep your foot on the anti-tipper and
lower the chair slowly forwards softly to the ground.
4.3.3 Tilting by the User
 Make sure your feet are on the footplates and will not slip off.
 Release both brakes.
 Grasp both push rims and give a firm, sudden forward push immediately
before the obstacle, continue the momentum (be ready to keep pushing)
until the obstacle is mounted.
CAUTION:
 This method should only be attempted by people experienced in wheelchair
use. Strong arms are also necessary. It is always better to have the help of
an attendant.
 Leaning backwards causes the caster to rise higher BUT it is much safer to
lean forwards and stay balanced.
4.3.4 Going Down Curbs
Please note: It is always better to avoid curbs where possible by using ramped
curbs or slopes and this operation is best attempted with the aid of an
attendant.
4.3.4.1 Going Down Curbs Forwards With an Attendant
CAUTION:
 This is the more difficult method and can jar the user but allows a better
view of traffic.
 Be careful that the anti-tipper does not get caught on the curb causing the
user to fall.
CAUTION:
NEVER ALLOW THE CHAIR TO TIP FORWARDS WHEN GOING DOWN A
CURB.
 Position the chair so that the front casters are near the edge of the curb and
make sure that the road is clear.
 Move the chair slowly and carefully forwards while tilting it back slightly. Be
ready to take the weight when the rear wheels cross the curb edge. Ensure
that both rear wheels touch the ground at the same time to avoid tipping the
chair.
 Gently lower the front casters AVOID JARRING THE USER.
4.3.4.2 Going Down Curbs Backwards With an Attendant
CAUTION:
This is the easier and smoother method BUT it requires the attendant to step
backwards into the road.
 Back the chair to the curb edge and be careful that the back wheels are
equally near the edge.
 Grasping the push handles, gently lower the rear wheels onto the road. Be
prepared to control the weight as it descends and ensure that the back
wheels touch ground at the same time.
 Tilt the chair back slightly and pull the tilted chair far enough into the road so
that the casters and footrests can be lowered clear of the curb
4.3.5 Going Up Curbs
Please note: This operation is best attempted with the aid of an attendant and
the best method is to go up curbs forwards as this maintains the direction of
travel and is physically less demanding for the attendant.
4.3.5.1 Going Up Curbs Forwards With an Attendant
 As the footrests nearly touch the curb tilt the chair. The chair should be
tilted just high enough to allow the front casters to roll smoothly onto the
pavement.
 Push the chair forward until the rear wheels are touching the curb. Then,
continuing the movement, lift at the push handles while moving the chair
forwards.
4.3.5.2 Going Up Curbs Backwards With an Attendant
Please note: for safety's sake we do not recommend using this method.
4.3.6 Going Up or Down Steps/Stairs
Please note: avoid flights of steps particularly if no extra help is available. Use
ramps or lifts wherever possible.
Two attendants are necessary, each capable of carrying at least half of the
combined weight of the person and the wheelchair.
Each helper should bend at the knees and grip the main frame: with the front
attendants hands just under the front of the seat, with the back attendant’s
hands holding the frame just under the push handles.
CAUTION:
Never hold on to movable or detachable parts.
ALL LIFTING SHOULD BE DONE WITH A STRAIGHT BACK.
Straighten legs to lift the chair. Carefully carry it up or down steps; be aware of
how you place your feet -- do not cross them and trip yourself up.
4.4 Storing
Make sure the wheelchair is folded when stored.
SUGGESTION:
Please store the wheelchair in a location where it is out of direct sunlight, rain
and dew. For more details, consult your Karma dealer.
WARNING: Don't put anything on the
wheelchair while it is in storage. Storing goods on a
folded or unfolded wheelchair will cause damage and is
not covered under warranty. (See Right Figure.)
4.5 Transportation
Do not use other transportation to pull the wheelchair.
This Karma wheelchair model in its standard configuration has passed crash
test requirements according to ISO 7176-19 regulations. S-105 series can be
used for transport in vehicles that have been specially adapted for this purpose.
The wheelchair must be securely fastened in the vehicle according to the
methods described on the following pages.
Karma always recommends that the user be transferred into car seat with a
safety belt or harness while in a transport.
SUGGESTION:
Remember that the best solution is always to move the user from the
wheelchair into a normal car seat.
4.5.1 Before use
CAUTION:
If the back angle of the wheelchair is adjustable, do make sure that the
wheelchair backrest should be positioned as close as possible to 90 degrees.
 Please detach all easily removable accessories from the wheelchair and
store them in a safe place where they cannot move around and become a
safety hazard.
 A four point tie-down system should tightly fasten the lower wheelchair frame
(hook mark
) to the transport vehicle.
 An occupant restraint system using both a pelvis and harness must also be
fastened to the transport vehicle to insure user safety. Again, please refer to
the restraint system's instructions.
 The attendant / transporter must double-check all fastening points for proper
connection and tightness to assure the wheelchair user’s safety. The
attendant / transporter must be fully aware of the fastening system's usage
and its weight limitations.
 See http://www.unwin-safety.com/ for more information.
CAUTION:
When transporting or lifting, never hold on to attachments or accessories
(front/rear wheels, hand rims, caster, footrests, armrests, anti-tippers etc.).
All lifting should be done with a straight back. Straight legs to lift the chair.
Carefully carry it up or down steps; be aware of how you place your feet, do not
cross them and trip yourself up.
4.6 Safety Belt
How to assemble and disassemble the Safety Belt
 Loosen the fourth and fifth screws of both side of seat upholstery and insert
the Safety Belt in between the fourth and fifth screw holes. (Figure 4.30.)
 Keep the safety Belt in 45 deg for comfortable usage. (Figure 4.31.)
 Put the seat upholstery back and tighten screws.
Figure 4.30

Maintenance
The Safety Belt is made from 100% polyester fiber and the clasp is made from
plastic. It does not require any maintenance but should be inspected every
month to ensure that the edges are not frayed and weekly to make sure that it
correctly fits the user. If there are any signs of deterioration, please replace it
immediately.
5. INSPECTION AND MAINTENANCE
5.1 Daily Check
Check the following items before traveling. If you find anything abnormal, visit
your Karma wheelchair dealer for further inspection before using it.
 Examine brakes, checking for wear, damage and misalignment. Replacing
or adjusting the brakes should be carried out by your approved repairer.
 Check that the hand grips are not damaged and are securely bonded to the
push handles.
 Check anti-tippers are not damaged and are securely attached.
 Check that the anti-tippers' wheels and frame are not damaged and are
securely mounted.
 Before using the wheelchair, make sure all nuts and bolts are tight. Check
all parts for damage or wear and have a qualified technician replace it if
necessary. Check all parts for proper adjustment. Inspect brakes for proper
operation.
 The wheels and tires should be checked periodically for cracks and wear,
and should be replaced by a qualified technician.
 A qualified technician can be found at an authorized distributor/dealer.
CAUTION:
Visit a Karma wheelchair dealer for inspection and maintenance if you find
anything abnormal.
