4 HANDLING TIPS
The Gendron MRI Transport Wheelchair has been designed and engineered to perform as a
stable and well balanced unit when used for its intended purpose. However, it is possible to tip
the MRI Transport Wheelchair over if it is used improperly or if you move beyond the center of
gravity. You may want to consider the use of a positioning belt, available from your distributor
or www.grahameld.com, to maintain proper weight distribution. We urge you to learn the
characteristics of your transport wheelchair. It is most important to learn safe methods to perform
the daily activities basic to your lifestyle. Consult your medical professionals for assistance in
developing the skills and proper techniques to perform all activities safely.
BALANCE
Proper balance is the key to maintaining the stability of your transport wheelchair. Reaching,
bending, and transferring to or from a wheelchair will change your weight distribution and center
of gravity. When performing such activities, do so as instructed in the following paragraphs to
avoid tipping the wheelchair.
TRANSFER
WARNING: Always ensure the transport wheelchair is on a stable, level surface before
transfer.
WARNING: Always engage wheel locks before transfer.
WARNING: Do not step on the footplates; this could cause the transport wheelchair to tip.
Fold them up, and either detach them, or swing them aside.
WARNING: There is a critical moment when there is little or no seat platform beneath you.
Take every precaution to reduce this unsupported distance before you attempt transfer.
Patient Lift Transfer Transfer Board Transfer
Transferring into or out of a transport wheelchair is a very difcult maneuver; always exercise
extreme care even when transferring with the aid of an attendant, a patient lift (shown at above
left), or a transfer board (shown at above right). Consult your medical professionals for assistance
in developing your individual transfer technique. Engage both wheel locks and ensure the
wheelchair is stabilized and will not move or slide during the transfer. Take extra precautions to
prevent tipping. Use good body mechanics to prevent personal injury.

GD_MR-INS-LAB-RevA21 • 4000MRQ2 / 4650MR / 4850MR MRI Transport Wheelchair User Manual 10
REACHING / BENDING
WARNING: Always turn the casters frontward to provide stability while reaching. If in
doubt, ask for assistance or use a device that will extend your reach without requiring you
to shift your weight.
Although it is not recommended, you may nd it occasionally necessary to lean or reach from your
transport wheelchair. Consult with your healthcare professional for assistance in developing your
personal safe reaching or moving techniques suited to your ability and restrictions.
REACHING / BENDING FORWARD OR SIDEWARD
WARNING: Do not attempt to reach objects if you are required to move forward in the seat.
Do not attempt to retrieve objects from the oor if you must reach down between your
knees. Do not shift your weight in the direction that you are reaching and/or bending; this
could cause the transport wheelchair to tip.
Reach Forward Reach Sideward
1. Maneuver the transport wheelchair as close as possible to the object you wish to reach.
2. Rotate both casters fully forward: Go forward, and then back the transport wheelchair toward
the object to swing the casters fully forward.
3. Engage both wheel locks.
4. Ensure the casters are rotated fully forward before reaching. If not, repeat step 2.
REACHING / BENDING BACKWARD
WARNING: Do not engage the wheel locks while reaching or bending backward. Should
your weight suddenly shift accidentally, it is better to roll in that direction than to tip over.
WARNING: Do not lean over the back upholstery; this could cause the transport wheelchair
to tip.
1. Maneuver the transport wheelchair as close as possible to the object; the rear wheels will limit
how close you can get.
2. Rotate both casters fully forward: Go forward, and then back the transport wheelchair toward
the object to swing the casters fully forward.
3. Reach only as far as your arm will extend without changing your sitting position. If in doubt,
reposition the transport wheelchair or ask for assistance.

RAMPS AND INCLINES
WARNING: During descent, the footplates' lowest point should be no closer to the ground
than 2 1/2 inches to permit proper clearance.
WARNING: Do not attempt inclines without anti-tippers installed. Do not attempt any incline
or decline of more than 6 degrees (10% grade, or one foot of rise or fall per ten feet of ramp
length).
WARNING: Do not use wheel locks to slow your descent. Attempting to use wheel locks
is likely to result in accidental locking that could cause the transport wheelchair to stop
abruptly, suddenly pitch forward, or tip sideways.
WARNING: Avoid changing direction while descending a ramp or incline, as this could
cause instability.
Most people are capable of negotiating short inclines without assistance, depending upon upper
body strength, endurance, and the degree of incline. Know your own strength and endurance
capabilities and limitations before attempting to negotiate an incline or decline. Practice with an
attendant or healthcare professional rst before attempting any inclines, declines curbs or ramps.
Always inspect the ramp for hazards such as holes, slippery or uneven surfaces, etc. before
starting up or down. If you can not see the entire ramp, ask someone to inspect it for you.
ASCENT
Lean the upper part of your body slightly forward,
as shown above, as you ascend the incline. If it
becomes necessary to stop on the incline, avoid any
abrupt or sudden forward movement as you resume
climbing; this could cause tipping.
DESCENT
Always face forward when going down a ramp, but
do not lean forward; this could cause tipping. Lean
slightly backward to increase stability. It is critical
to keep the transport wheelchair under control at
all times. Descent should be made slowly and safely
by grasping the handrims; however, use care, as
friction heat will be generated. We recommend the
use of gloves to reduce the effects of friction heat,
but going slower is a better alternative.
CURBS
Curbs should only be negotiated with the assistance
of an attendant. When you encounter curbs, nd a
way around, or use the ramps now available in most
locations. If there is no ramp available, avoid the
curb by using the disabled-designated elevators now required in most locations.

CURBS — WITH ATTENDANT
Going up (Method 1) Going Up (Method 2) (Going Down)
WARNING: When approaching a curb, ensure the hand grips are securely fastened and do
not turn or slip off.
Curbs should only be negotiated with the assistance of an attendant. The following are
suggestions only for curb negotiation. It is important for you to develop your own safe technique
that is best suited for your abilities with the aid of your healthcare professionals.
Going Up (Method 1)
When approaching a curb, ensure the hand grips are securely fastened and do not turn or slip
off. Tilt the transport wheelchair backward to its balance point and move forward until the front
casters pass over the top of the curb. Lower the front casters slowly onto the curb while lifting the
transport wheelchair by the push handles, and push forward until the rear wheels roll up and over
the curb. Ensure the wheelchair has completely cleared the curb and can not roll backward.
Going Up (Method 2)
Ensure the hand grips are securely fastened and do not turn or slip off. Turn the transport
wheelchair around and back up until the rear wheels are against the curb. Tilt the wheelchair back
to its balance point and lift up by the push handles while pulling the wheelchair up and over the
curb. DO NOT let the front casters down until the wheelchair is back far enough to clear the curb.
Going Down
Ensure the hand grips are securely fastened and do not turn or slip off. While standing behind
the transport wheelchair, turn the wheelchair around and carefully back down the step. Hold the
handgrips tightly and pull the wheelchair to where the rear wheels reach the curb edge, then slowly
roll the rear wheels down onto the lower level. After the wheels are safely on the lower level, tilt the
wheelchair back to its balance position and turn it face forward. Lower the front casters carefully
by placing one foot on the tipping lever and gradually decreasing the force of exertion.
STAIRS AND ESCALATORS
WARNING: Never attempt to negotiate stairs or escalators in your MRI Transport
Wheelchair.
Stairs and escalators are dangerous obstacles. If you encounter steps and there is no ramp
available, avoid the steps by utilizing the disabled designated elevators now required in most
locations.
WEIGHT TRAINING
WARNING: This transport wheelchair is not designed or tested as a seat for weight training.

LIST OF TOOLS
The tools and cleaning supplies listed will assist in the following procedures.
30 weight oil (available at most auto parts stores), Phillips screwdriver; clean, soft cloth; and mild soap
and water solution
GENERAL CARE
Always evaluate the overall operation of your transport wheelchair. It should function with ease
and should travel straight without excessive drag or pull to one side.
Remember, your Graham-Field authorized distributor knows your transport wheelchair best
when it comes to service and repairs. Contact your authorized distributor with any questions or
concerns regarding the safe operation and maintenance of your transport wheelchair. Regular
maintenance is essential for your safety and continued operation of your wheelchair.
CHECK TIRE WEAR
Examine tires at least once a week for surface wear and cracks and replace them as needed.
Replace solid rubber tires when they become loose on the rims or cracks appear.
CHECK HANDRIMS
Check handrims at least once a week. Inspect each handrim for rough or sharp edges and, if any
are found, replace handrims immediately. Ensure that all hardware is properly aligned and secure.
CHECK WHEEL LOCK ENGAGEMENT
Check wheel lock engagement at least once a week. See Adjust wheel locks in the ADJUSTMENTS
section to adjust wheel lock engagement. If a wheel lock is worn or damaged, replace it
immediately. Inspect the hardware for looseness or signs of wear.
Ensure the locking mechanism operates smoothly. The locking assembly should be tight enough
so that the wheel can not rotate or the lock slip. Check that the locking shoe does not press
against the tire when in the unlocked position. Excessive force should not be required to either
engage or release wheel locks. Oil the wheel lock pivot points with one or two drops of 30 weight
oil. Remove excess oil and dirt.
CHECK ANTI-TIPPERS
Check the anti-tippers at least once a week. Ensure anti-tippers are securely fastened and properly
positioned.
CHECK HANDGRIPS
Check handgrips at least once a week. Ensure they are not ripped; ensure they are tight and
securely fastened.
CHECK CROSSBRACES
The locknut on the pivot bolt is to be snug, but not overly tight. If the pivot bolt becomes worn,
replace it and the locknut.
CHECK UPHOLSTERY
Check upholstery at least once a month. Inspect for rips, tears and worn spots. Ensure that
all upholstery-attaching screws are present, properly aligned, and well-secured. Use a Phillips
screwdriver to tighten upholstery mounting screws. Check attaching screws for sharp edges or
stripped screws, and replace if found.
WARNING: Worn or torn upholstery, or upholstery with loose hardware, must be replaced
immediately. It may not support body weight.

CHECK REAR WHEEL ADJUSTMENT
Inspect the wheels at least once a month. Check alignment by elevating the rear of the transport
wheelchair on a stable object until the rear wheels clear the ground, or placing the transport
wheelchair upside down in a stable position such that the wheels can spin freely. Spin the wheels;
there should be no wobble or sideplay, and the wheels should spin freely without binding. The
bearings should be clean and rotate smoothly. Check rim sideplay to verify that bearings are not
too loose. If there is a problem, contact your Graham-Field authorized distributor. If adjustment is
required, this should be done by your Graham-Field authorized distributor only.
CHECK ARMS
Check arms at least once a month. Inspect for sharp edges or cracks which could weaken the arm,
and replace if found. Ensure all attaching screws are present and tight. Check for burrs on any
screw heads and replace if found. Ensure that screws do not extend into the padding. Conrm that
the post at base of arm ts correctly in the socket, snug but not binding.
CHECK BACKPOSTS / PUSH HANDLES
Check backposts at least once a month. Ensure that all mounting hardware is securely fastened
and that the backposts are not bent or damaged. Contact your authorized distributor if you
observe cracking or peeling paint or plating.
CHECK FOOTRESTS
Check footrests at least once a month. Inspect the locking mechanisms to conrm sure t. Check
for cracks, burrs, or sharp edges, and replace if found. Ensure the footrest will automatically lock
securely in place and will not accidentally unlock.
CLEANING YOUR MRI TRANSPORT WHEELCHAIR
Wipe off base and seat frame frequently, at least once a week, using a soft cloth. Dry the transport
wheelchair immediately if exposed to moisture. Clean the frame every three months with a mild
soap and water solution. The frame does not need to be waxed. Do not use solvents, abrasive
waxes, caustic chemicals or spray silicone. Never use abrasive cleansers; they could scratch the
nish. Never use steam or high pressure cleaners. Clean upholstery and plastic components at
least once a month with a mild soap and water solution.
CHECK CASTERS
Check the caster stems for proper rotation at least every three months. The caster forks must
swivel freely to facilitate steering and handling. Adjusting the stem nut varies the amount of force
required to turn the caster. If the nut is too loose, the caster will utter or shimmy; if too tight,
the transport wheelchair will be difcult to steer. If the caster stems require adjustment, or the
stem bearings require replacement, contact your Graham-Field authorized distributor. Ensure that
stems are rmly attached to forks, and that forks and stems are not bent. Evaluate all threads,
locking nuts and bearings.
CHECK WHEEL BEARINGS
Have your Graham-Field authorized distributor check caster and rear wheel axle bearings at least
every six months.
