Owner’s Operating and
Maintenance Manual
For Standard Wheelchairs
INTRODUCTION
Standard wheelchairs are the result of extensive engineering research, and rigid quality assurance testing. Every new component
and finished assembled product must satisfy our high standards.
We are dedicated to maximum mobility and independence, and have developed what we believe is the finest line of wheelchairs
available, providing safety as well as comfort and function. This operating manual should help you achieve optimum safety,
performance, and confidence in your wheelchair.
Many activities require the wheelchair user to reach, bend, and transfer in and out of the wheelchair. You should be instructed in
the proper use of your chair before attempting these movements.
It is imperative that the procedures and cautions outlined in this manual be observed for your own safety. You should develop a
routine inspection and maintenance schedule and should periodically review the recommended operating techniques.
Please, read the manual thoroughly BEFORE using your wheelchair, ensure you understand the instructions and refer to it
regularly for maximum safety and performance.
We are pleased that you have chosen our wheelchair and trust it will serve you well.

The Manufacturer recommends that only heavy duty constructed wheelchairs should be used for individuals
weighing more than 113kg(250 Pounds).
Further, the activity level of each wheelchair user is important. For instance, a 77kg (170 Pounds ) active
wheelchair user could subject the wheelchair to more stress than a 113kg(250 Pounds) passive user. The
manufacturer recommends that very active users consider the use of heavy duty construction.

SAFE AND HANDLING
“Safety and handling” of the wheelchair requires close attention of the wheelchair user as well as the attendant. This manual
points out the most common procedures and techniques involved in the safe operation and maintenance of the wheelchair. It is
important to practice and master these safe techniques until you are comfortable in maneuvering around the frequently
encountered architectural barriers.
Use this booklet only as a “basic” guide. The techniques that are discussed on the following pages have been used successfully
by many.

5
Individual wheelchair users are subject to various capabilities and limitations and often develop skills to overcome their
disabilities in daily living activities that may differ from those described in this manual. Each individual is encouraged to try
what works for him/her in overcoming architectural obstacles that the wheelchair user may encounter. The techniques described
in this guide are a stating point for the new wheelchair user and attendant with “safety” as the most important consideration for
all.
Coping with everyday obstacles
Coping with the irritation of everyday obstacles such as curbs and stairs can be alleviated somewhat by learning how to
manage your wheelchair. Always keep in mind your center of gravity to maintain stability and balance.
Percentage of Weight Distribution
Many activities require the wheelchair owner to reach, bend and transfer in and out of the wheelchair. These movements will
cause a change to the normal balance. The center of gravity and weight distribution of the wheelchair .
To determine and establish your particular safety limits described on the following pages, activities involving reaching, bending
and transferring SHOULD FIRST BE PRACTICED WITH A QUALIFIED HEALTH PROFESSIONAL PRESENT.
Tilting
When tilting the wheelchair, an attendant should grasp the push handles securely, making sure that the handle grips are firmly
attached. Inform the chair occupant before tilting the chair and remind him/her to lean back. Be sure the occupant’s feet and
hands are clear of all wheels. Place one foot on the tipping lever and apply a continuous motion until the balance point is
achieved. At this point, the attendant will feel a difference in weight distribution (This usually occurs at about 30°angle). Turn
the wheelchair in the required direction if necessary. Lower the front end, placing one foot on the tipping lever and grasping
the push handles to slowly lower the chair in one continuous movement. Do not let the chair drop the last few inches to the
ground. This may result in injury to the occupant.
After mastering the techniques of tilting the chair ，use this procedure to tackle curbs, short stairs, etc
CAUTION
Do not tilt the wheelchair without assistance.

6
curbs
METHOD1-The attendant should tilt the chair until the front casters clear the curb. Roll the chair forward and lower the front
casters to the sidewalk. Push the chair forward until the rear wheels roll up and over the curb.
METHOD2-The attendant should stand on the sidewalk and turn the chair so that the rear wheels are against the curb. The chair
should be tilted back to the balance point and, in one continuous movement ，the rear wheels should be pulled up and over the
curb. DO NOT return the front casters to the ground until the chair back has been pulled backward for enough to clear the edge
of the curb.
ESCALATORS? SORRY!
Do not use an escalator to move an occupied wheelchair between floors.
Serious bodily injury may occur.
Stairways
Extreme caution is advised when it is necessary to move an occupied wheelchair up or down stairs. We recommend using two
attendants and making thorough preparations. Make sure to use only secure, non-detachable parts for hand hold supports.
Following this procedure for climbing the stairs.
1. After the chair has been tilted to the balance point, one attendant (in the rear) backs the chair against the first step, while
securely grasping the push handles for leverage.
2. The second attendant, with a firm hold on a non-detachable part of the front framework, lifts the chair up an over the stair

7
and steadies it as the first attendant places one foot on the next stair and repeats the procedure.
3. The chair should not be lowered until the last stair has been negotiated and it has been rolled away from the stairway.
Transferring to and from other seats
This activity maybe performed independently provided you have adequate mobility and upper body strength:
Remove arm by depressing the flip-lock and lifting the arm off. (If equipped)
Position the chair as close as possible along side the seat to which you are transferring, with the front casters pointing toward it.
Lock wheels. Swing legrests out or remove. Shift body weight into seat with transfer.
During independent transfer, little or no seat platform will be beneath you. Use a transfer board if at all possible.
Reaching, Leaning and Bending
WARNING!
Before attempting to transfer in or out of the
wheelchair, every precaution should be taken to
reduce the gap distance. Also be certain the wheel
locks are engaged against the large wheels from
moving (turn both casters toward the object you are
CAUTION
Do not attempt to lift a wheelchair by lifting on the armrests or legrests of a wheelchair equipped with
removable (detachable) armrests or legrests. Lifting by means of the armrests or legrests of a wheelchair
designed with removable features may result in injury to the user or damage to the wheelchair.

When reaching, leaning or bending it is important to use the front castors as a tool to maintain
stability and balance. Proper positioning is essential for your safety.
MAINTENANCE AND ADJUSTMENTS
FRONT RIGGINGS
Reaching, Bending-----FORWARD
Position the front caster so that they are extended as for forward
as possible and activate wheel locks, DO NOT LEAN
FORWARD OF THE ARMRESTS.
Reaching, Bending----BACKWARDS
Position wheelchair as close as possible to the desired
object.
Point casters forward to create the longest possible
wheelbase.
Reach back only as far as your arm will extend without
changing your sitting position .
WARNING
DO NOT attempt to reach objects (1) if you have to move forward in the seat or (2) if you have to pick them up from the floor
by reaching down between your knees.
WARNING
DO NOT activate the wheel locks-it is better to roll backwards than tip over. DO NOT lean over the top of the back
upholstery. This will change you center of gravity and may cause you to flip over.

9
To Adjust Length
Adjustments are made to desired length with individual sitting in the wheelchair with feet on
footplates. Use a spanner to loosen the bolt at the side of the footrest support hanger. Adjust
the footplate up or down as needed to provide maximum support of thighs on the seat
upholstery, then re-tighten the bolt. .
To permit proper clearance the lower point of the footplate should be at least 6cm(2 5”) from the
ground or floor.
Warning! -Ensure that desired front rigging adjustment does not cause pressure to legs at front of seat
upholstery. Such a condition could cause injury to the occupant.
Swing-away Elevating Leg rest
Raising
1. Lift up on footplate or support assembly behind the calf pad until desired position is
achieved.
2. Release the footplate; it will automatically lock into position.
Lowering
1. Firmly grasp leg rest close to foot pate and provide vertical support.
2. Activate the leg rest lever by pushing it out.

10
3. Slowly lower the footplate until desired position is reached.

of your wheelchair.
Upholstery cleaning
Use a commercial NYLON material cleaner or mild soap and water.
Metal Parts
Clean all metal parts with auto wax or similar compounds. DO NOT use any abrasive cleaner or
material that will scratch the finish.
Tyres
Periodically examine tyres for wear and replace as needed. Pneumatic tyres should be checked
weekly and kept properly inflated (see tyre side wall for recommended inflation level). Solid
tyres should be replaced when they become loose on the rim. Cracks appear or worn flat.
zImportant! -Replace any worn or damaged parts immediately, e.g. tyres; armrest; skirt guards; out of
round wheels; cross braces; upholstery; frame parts.
z
Wheels
The large wheels should be checked at least monthly for correct axle bolt tightness. If the
wheel is loose or wobbles, release the locknut and tighten the axle bolt slightly. To test for
correct tightness, lean the chair to one side and spin the adjusted wheel. The wheel should stop
spinning by “running sown” slowly. If it stops abruptly, it is too tight and the axle bolt should be
loosed.
Caution!
Do not use paint remover, liquid brush cleaner or similar solvents on upholstery.
Caution!
Do not use strong detergent, abrasive cleaner or any other material that will scratch the finish.

13
Casters
The casters are secured to the caster fork by axle nut and bolt. This nut and bolt should be periodically checked to allow a snug,
but free spinning wheel. The caster fork swivel allows the wheelchair to turn properly. An adjustment locknut is located under
the caster cap. Pry this cap off to expose the adjustment locknut. If the locknut is too tight the wheelchair will be difficult to steer.
If the locknut is too loose, the caster will flutter or shimmy and may cause the chair to tip.
To check for correct tightness:
1. Tip the chair backward resting the push handles on the floor.
2. Raise the caster wheel towards the ceiling then gently push downward to either side. The wheel and fork should freely
swivel to the bottom of its arc and hang straight toward the floor after a pendulum-type swing.
3. If the wheel stops angled to one side, loosen the locknut on the fork stem slightly.
Crossbraces
Ensure that the nut and bolt holding the crossbraces together are tightened while remaining loose enough in the braces to permit
easy folding of the wheelchair.
Wheel locks
Activate the brakes by pushing the handles forward (push-lock style). To adjust a brake, loose the carriage nut and bolt which
Note!
Periodically lubricate the center bolt. This will ensure the wheelchair will “ flex ” when crossing uneven surfaces.

run through the mounting bracket and frame. Slide the clamp toward the rear wheel until the wheel brake shoe is embedded
approximately 1/8” into the tyre material when the handle is engaged in the lick position. Re-tighten the nut and bolt to secure
the mounting bracket in the desired position. Inspect for correct locking action before using. If brake becomes worn or damaged,
replace the entire assembly immediately.
