DO NOT attempt to lean over the top of the back upholstery to reach objects.
Before leaning or reaching forward, make sure to rotate the casters straight ahead toward the front of the wheelchair and engage the wheel
locks to prevent the wheelchair from tipping over or moving.
DO NOT tip the wheelchair without assistance. DO NOT lean the wheelchair back since this can cause the wheelchair to tip over. If trying to reach
objects, reach back only as far as your arm will extend without altering your seating position.
Any person assisting the rider in maneuvering or lifting of the wheelchair must have sufficient strength and be able to see obstacles in the path
of travel. When learning a new assistance technique, have an experienced assistant help you before attempting it alone. Remember to use good
body mechanics.
Contact with water or excess moisture may cause the non-aluminum wheelchairs to rust or corrode. DO NOT use the chair in a shower, pool
or other body of water. Avoid excess moisture (example: do not leave the chair in a damp bathroom while taking a shower). Dry the chair
immediately if exposed to moisture.
When cleaning the hand grips, use only a clean towel lightly dampened with cool water. Ensure the hand grips are dry before use. Use of soap or
ammonia based cleaning solutions may result in the hand grips sliding off.
If the wheelchair is exposed to extreme temperatures, high humidity and/or becomes wet, check the hand grips to ensure they are not loose and
do not twist on the handle.
Avoid storing or using the wheelchair near open flames or combustible smoldering products.

√ Have any problem found repaired promptly with authorized parts.
Guidelines:
Safety & handling of wheelchairs
Center of gravity, balance and stability
This Medline wheelchair has been designed to be safe and stable during normal transport activity as long as proper balance is maintained. The
point at which a wheelchair will tip forward, backward, or to the side depends on its center of balance. To assure stability and proper operation
of the wheelchair, the center of gravity must be maintained in the chair. Center of gravity is the point at which all the weight of an object can be
considered to be concentrated and represents the balance point.
Most activities such as transferring in and out of the wheelchair, bending, and reaching affect the center of gravity and weight distribution
of the wheelchair. Addition of accessories such as a backpack will also re-distribute weight. Loss of proper balance may cause the chair to tip
over. Use of the seat belt is advised to help maintain stability by minimizing movement within the wheelchair seat. The use of anti-tip devices,
especially when maneuvering on ramps or inclines, will also enhance safety.
To assure safe operation of the wheelchair, ALL of the Warnings and Instructions in this manual must be followed. Failure to do so may result in
tipping the wheel chair over or causing the user to fall which may result in serious bodily injury or damage to the wheelchair.
Some basic wheelchair safety guidelines follow. The guidelines are critical for standard wheelchair use, however, the principles also hold true for
transport chairs. If any of the following activities are required while using the wheelchairs, these guidelines must be followed to ensure safety
and to avoid potential injury to the user or the transporter and to avoid damage to the chair.
Reaching / leaning / bending – forward or sideways
• Position the wheelchair as close as possible to the object.
• When reaching forward make sure the front casters are pointing in a forward position (Fig. 1). This extends the wheel base and will help
stabilize the chair.
• When reaching sideways position the casters to provide the greatest stability side to side (Fig. 2).
• Make sure the wheel locks are engaged before activity.
• DO NOT attempt to reach for objects if doing so means you must move forward in the seat. DO NOT shift your weight toward the direction
you are reaching.
• DO NOT attempt to reach objects if you have to pick them up from the floor by reaching down between your knees.
• DO NOT shift your weight or seat position toward the direction you are reaching.
Guidelines:
Safety & handling of wheelchairs
Reaching / leaning – backward
Position the wheelchair as close as possible to the object.
Make sure the front casters are pointing in a forward position (Fig. 3). This extends the wheel base
and will help stabilize the chair.
DO NOT engage the wheel locks – if your weight shifts while reaching backwards it is better for the
wheelchair to roll than to tip.
DO NOT lean back over the top of the back upholstery.
Reach back only as far as your arm will extend without changing your position in the seat (Fig. 3).
Transferring into and out of the wheelchair
Transferring to and from the wheelchair is a significant task that requires balance, agility and upper
body strength. Practice with your healthcare provider before attempting transfers. If possible,
always use a transfer board and have assistance available.
• Position the wheelchair as close as possible.
• Position both casters parallel to the seat you are transferring to.
• Make sure both wheel locks are engaged.
• Remove the armrest and the footrests that are in the transfer path.
• DO NOT put weight on the foot rests.
• Transfer as far back into the seat or onto the bed/chair as possible.
• On the recliner wheelchair models, make sure the seat back is in the upright position and the stabilizer bar is securely in place.
Obstacles
Obstacles such as floor threshold strips, uneven floors, cords or items on the floor, or cracks in pavements can damage your wheelchair and may
cause loss of control or a tip over. Be alert! Scan your path and avoid any items that may cause instability.

Curbs, steps and stairs
Do not attempt to negotiate curbs or single steps without assistance. Ask your healthcare worker to provide instructions regarding safe
wheelchair use for curbs, steps and stairs. Proper body mechanics and awareness of the center of gravity is crucial for these maneuvers. The
step tubes (Fig. 4) at the back of the chair are utilized to tilt the wheelchair backwards until the balance point is achieved
and the front casters clear the curb/step. Gently lower the front wheels to the ground and slowly roll the wheelchair forward until the rear
wheels roll up over the curb/step.
Extreme caution is required if it is absolutely necessary to maneuver an occupied chair up or down
stairs. Two assistants with adequate body strength and endurance must be present. DO NOT lift
the chair by any removable parts (i.e. swing-away footrests). Make sure the hand grips are not
loose. Techniques for going up or down steps should be received from a health care professional
familiar with wheelchair use and practiced before attempting to transport on stairs. If at all
possible, an alternate means of transport up or down stairs is recommended.
Ramps / inclines
The assistant must know their capabilities and limitations in terms of strength and endurance
before attempting to go up or down a ramp. Slopes will change the center of gravity. DO NOT
attempt to negotiate steep inclines greater than 10% (6 degrees, or one foot of rise or fall for every
ten feet of ramp length) without an experienced assistant. Use of anti-tip devices are encouraged,
however, they may not prevent a tip-over. Sometimes anti-tip devices may catch at the beginning
of a ramp. If this occurs, they will need to be disengaged and extra care should be taken. Backpacks
or other gear on the back of the wheelchair will cause it to tip backward more easily. Training and
practice negotiating ramps with a healthcare professional is recommended.
• Go as straight up or down the incline as possible.
• Check the ramp for any obstacles, bumps, depressions, or wetness before beginning.
Ask for additional assistance if necessary.
• Stay in the center of the ramp if possible.
• Avoid changing direction while on the ramp as this may cause loss of control of the wheelchair.
• Avoid stopping on a ramp. Stopping may cause loss of control of the wheelchair. If stopping is
necessary, avoid sudden, abrupt forward movement when you resume propelling the chair as
that could cause instability.
• When going up an incline, the occupant should lean forward. This will adjust the center of
gravity to counteract the tendency of the wheelchair to tip backward.
• When going down a ramp, the occupant should face forward and lean backward into the seat.
Descent should always be done slowly.
DO NOT use wheel locks as brakes to slow down or stop the chair. Attempting to use the wheel
locks could result in accidental locking, veering or tipping to one side, or suddenly stopping.
• When going down a steep incline, the assistant should turn the chair and go down backwards to
avoid tipping the occupant out of the chair.
Basic information for wheelchair
assistants / transporters
Work with the wheelchair user’s healthcare professional or your institution to learn safe ways to assist that are within your capability and
comfort level. To prevent injury to yourself or the chair occupant use good body mechanics:
• Always tell the rider what you intend to do so he/she is ready for your actions and can assist with maintaining a balanced center of gravity
for stability.
• Bend at the knees, not at the waist. Keep knees bent, not locked straight.
• Use legs for strength, not the back or arms. This will help prevent back strain.
• DO NOT twist at the waist. Keep the torso facing the same direction as the hips and move the feet to turn. This will help prevent back strain.
• Maintain a straight back. Hunching or rounding the shoulders can cause back strain.
• DO NOT hesitate to call for additional assistance if needed.
• If you do not feel comfortable with an activity you are requested to assist with (such as negotiating a step or a steep incline), you may
decline to assist and should help find appropriate assistance.
• RECLINER models: Be prepared to support the weight of the occupant when reclining or returning the wheelchair back to the full upright
position.
• RECLINER models: Always stay in attendance when the wheelchair is in the reclined position.

General use instructions
Safety lap belt use (included with select models)
• The lap belt is provided to help the rider be safe and well positioned in the wheelchair.
• The lap belt should be initially fitted by a qualified healthcare professional or dealer.
• While sitting back in the chair, it should be adjusted to be sufficiently tight around the rider's pelvis to keep from sliding down without
causing discomfort.
• There should be sufficient room to slide a hand between your body and the belt.
• Adjust belt so that it buckles in the front.
Anti-tippers (included with select models)
• Rear anti-tippers help keep the chair from tipping and are recommended attachments for additional safety (Fig. 7).
• The use of anti-tippers is required on all recliner models.
Warning on use of anti-tippers
• Anti-tippers must be fully engaged. Ensure the release button of the anti-tipper fully protrudes out of the hole on the
bottom of the wheelchair frame.
• A 1.5-2"(3.8-5.0 cm) clearance between the bottom of the anti-tipper wheels and the ground/floor must
be maintained at all times.
Installing anti-tippers
1. Depress the release button and insert the anti-tippers with the anti-tipper wheels pointing toward the ground/floor into the wheelchair
frame tubing.
2. Ensure that the release button of the anti-tipper fully protrudes out of the hole in the bottom of the wheelchair frame tubing.
Important notes
There are potential finger pinch point areas at moving parts and between the seat frame and the seat cradles on some models. When
opening the wheelchair, take care not to place your hand or fingers between the seat frame and the seat cradles (if present) or on any other
moving parts.

Safety inspection & maintenance
It is highly recommended that the wheelchair be taken to a qualified dealer annually for a thorough inspection and maintenance / repair service.
General care
• Wipe off chrome / aluminum parts at least once per week using a clean, soft cloth.
• Clean all metal parts with auto wax or similar products.
• Dry the chair immediately if exposed to moisture.
• Do not use abrasive cleanser or materials that will scratch the finish of the chair.
• Clean the upholstery with a mild soap solution, rinse and wipe dry.
• Clean the hand grips with water only and dry thoroughly. Use of soap or ammonia based cleaning solutions may loosen the grips.
General
Inspect the entire wheelchair for broken parts, sharp edges and loose fasteners. Ensure that everything works and the chair rolls straight
without drag and does not pull to one side. Replace or tighten parts as needed. Inspect for bent frame and crossbars.
Frame and Cross braces:
Check that the frame and cross braces are not bent or dented. Check the tubing for cracks and rust. If such issues are found, take the wheelchair
to your local service dealer.
Upholstery
Inspect for any rips, tears or worn spots and replace as necessary. Inspect the upholstery screws and assure that all are present and tight.
Torn or worn upholstery may not support the user’s weight and could result in a fall with serious bodily injury.
Armrests
Check for cracks, looseness, or sharp edges.
Hand grips
Ensure the hand grips are tight and secure on the handles. They should not move or twist.
Footrests / legrests
Ensure the legrest assembly release works properly. Ensure the assembly automatically locks securely into place when attached and will not
accidentally unlock.
Front caster forks
Verify the forks swivel freely without binding. Check to ensure the casters roll freely by lifting the chair and spinning the castor. The castor
should come to a gradual stop. If the nut is too loose, the castor will flutter or shimmy. If the nut is too tight, the chair will be difficult to steer.
Check the bearings and clean the fork stem housing.
Front casters and rear wheels
Ensure the castor/wheel axle and nuts are tight. The fork housing and the rear and front wheels are constructed with low maintenance, sealed
bearings to keep dirt out and increase the durability of the chair. Bearings are also protected with an additional bearing spacer component.
Check that the wheels are not warped, cracked or otherwise damaged and the spokes are not broken. Replace as needed. Assure that the wheels
spin freely. Replacement and maintenance of wheel bearings should be completed by a qualified wheelchair technician only.
Front and rear tires
Solid tires require minimal maintenance. They should occasionally be cleaned with a damp cloth. Replace the tires if they become cracked,
excessively worn, or have flat spots.
Recliners (for models equipped)
Inspect the reclining mechanisms to ensure they are clean and work freely. Ensure the stabilizer bar locks securely into place.
