WARNING

without the seat positioning strap), Invacare strongly recommends ordering the seat positioning strap as an additional safeguard for the
wheelchair user. The seat positioning strap is a positioning strap only. It is not designed for use as a safety device withstanding high stress
loads such as auto or aircraft safety belts. If signs of wear appear, strap MUST be replaced IMMEDIATELY.

Wheel Locks
Wheelchair Tie Down Restraints
Wheelchair User
WARNING
DO NOT attempt to stop a moving wheelchair with wheel locks. Wheel locks are not brakes.
If the wheelchair is equipped with push to lock wheel locks, elevating legrests, and wheel lock extension handles, the wheel lock extension
handles MUST be removed before swinging the elevating legrests to the side, otherwise injury or damage may result. Interference between
the top of the elevating legrest and the wheel lock extension handle causes the wheel lock to disengage.
WARNING
Wheelchair users should NOT be transported in vehicles of any kind while in wheelchairs. As of this date, the Department of
Transportation has not approved any tie-down systems for transportation of a user while in a wheelchair, in a moving vehicle of any type.
It is Invacare’s position that users of wheelchairs should be transferred into appropriate seating in vehicles for transportation and use be
made of the restraints made available by the auto industry. Invacare cannot and does not recommend any wheelchair transportation
systems.
WARNING
As a manufacturer of wheelchairs, Invacare endeavors to supply a wide variety of wheelchairs to meet many needs of the end user.

capable of making such a selection.

3.3 Safety/Handling of Wheelchairs
Safety and handling of the wheelchair require the close attention of the wheelchair user as well as the assistant. 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 information only as a basic guide. The techniques that are discussed on the following pages have been used successfully by many.
Individual wheelchair users often develop skills to deal with daily living activities that may differ from those described in this manual. Invacare recognizes
and encourages each individual to try what works best for him/her in overcoming architectural obstacles that they may encounter. However, all
warnings and cautions given in this manual MUST be heeded. Techniques in this manual are a starting point for the new wheelchair user and assistant
with “safety” as the most important consideration for all.
Stability and Balance
WARNING
The seat depth, back height/angle, seat angle, size/position of the front casters, seat-to-floor angle, position of the rear wheels, correct
anti-tipper as well as the end user’s disability or end user’s physical condition and capabilities directly relate to the stability of the wheelchair.
Any change to one or any combination may cause the wheelchair to decrease in stability. These adjustments MUST be performed by a
qualified technician.
Seat-to-floor heights have specific positions depending on rear wheel size, rear wheel position, front caster size/position and seat-to-floor
angle. These adjustments MUST be performed by a qualified technician.
Be aware that carrying heavy objects on your lap while occupying the wheelchair may adversely affect the stability of the wheelchair,
resulting in serious bodily injury to the user, damage to the wheelchair and surrounding property.
This wheelchair has been designed to accommodate one individual. If more than one individual occupies the wheelchair this may adversely
affect the stability of the wheelchair, resulting in serious bodily injury to the user, damage to the wheelchair and surrounding property.
(Recliner Models Only)
ALWAYS make sure that the wheelchair is stable before using the recliner option.
ALWAYS return the back to the upright position before lifting the wheelchair.
ALWAYS engage both wheel locks while reclining or inclining (sitting up) the wheelchair.
ALWAYS return the back to the upright position before lifting the wheelchair.
Ensure the spreader bar is attached and secured before using the Jymni Recliner.
3 SAFETY
Invacare® Jymni™ Pediatric Series Wheelchair
20 Part No 1100868
To assure stability and proper operation of your wheelchair, you MUST maintain proper balance at all times. Your wheelchair has been designed to remain
upright and stable during normal daily activities as long as you DO NOT move beyond the center of gravity.
Virtually all activities which involve movement in the wheelchair have an effect on the center of gravity. Invacare recommends using seat/chest positioning
straps for additional safety while involved in activities that shift your weight.
DO NOT lean forward out of the wheelchair any further than the length of the armrests. Make sure the casters are pointing in the forward position whenever
you lean forward. This can be achieved by advancing the wheelchair and then reversing it in a straight line.
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 the weight distribution of the wheelchair. To determine and establish your particular safety limits, practice bending, reaching
and transferring activities in several combinations in the presence of a qualified healthcare professional before attempting active use of the wheelchair.
Proper positioning is essential for your safety. When reaching, leaning, or bending forward, it is important to use the front casters as a tool to maintain stability
and balance.
When changes to the left hand column occur, follow across the chart
and refer to the procedure that is checked (✓) to maintain the
proper stability, safety and handling of the wheelchair.

cause you to shift weight to one side of the wheelchair.
Reaching or lifting objects on the side of the wheelchair
can cause the chair to tip over sideways.
DO NOT lean over the tope of the back upholstery to
reach objects behind you, as this may cause the
wheelchair to tip over.

Coping With Everyday Obstacles
Coping with the irritation of everyday obstacles can be alleviated somewhat by learning how to manage your wheelchair. Keep in mind your center of gravity
to maintain stability and balance.
Tipping
When tipping the wheelchair, an assistant should grasp the back of the wheelchair on a non-removable (non-detachable) part. Inform the wheelchair occupant
before tipping the wheelchair and remind him/her to lean back. Be sure the occupant’s feet and hands are clear of all wheels and/or pinch points.
After mastering the techniques of tipping the wheelchair, use one of the following methods to tackle curbs, short stairs, etc.
Method 1 - Wheelchair With Step Tubes
Place foot on the step tube and begin to tilt the wheelchair toward you.
Apply a continuous downward motion until the balance point is achieved
and the front casters clear the curb. At this point, the assistant will feel a
difference in the weight distribution.
Roll the wheelchair forward and slowly lower the front of the wheelchair in
one continuous movement onto the sidewalk. Push the wheelchair forward
until the rear wheels roll up and over the curb.
