3NOTICE –READ BEFORE USE
As a manufacturer of wheelchairs, PDG endeavors to supply a wide variety of
wheelchairs to meet the many needs of the end user. However, final selections of the
type of wheelchair to be used by an individual rests solely with the user and his/her
healthcare professional capable of making such a selection. Thus it is recommend an
Assistive Technology Professional, clinical professional or therapist be consulted to
determined which model would best meet the wheelchair user’s mobility and
positioning needs.
All wheelchair set-up and adjustments must be performed by a qualified technician.
The options you choose and the set-up and adjustments have a direct impact on the
wheelchairs stability. Factors to consider that affect your safety and stability are:
a. User’s abilities and capabilities specifically of strength, balance and
coordination.
b. The types of daily hazards and obstacles encountered.
c. The specific dimensions, options and set up of the wheelchair. In particular
any changes to the seat height, seat depth, seat angle, back angle, size and
position of the rear wheels and front casters will change the stability of your
wheelchair. You should only make changes after consulting with a qualified
professional.
WARNING and CAUTION notices as used in this manual apply to hazards or unsafe
practices, which could result in personal injury or property damage.

4SAFETY SUMMARY
Operating Information Warning
Unless otherwise noted, all service and adjustments should be performed while the
wheelchair is unoccupied.
To determine and establish particular safety limits, practice bending, reaching and
transferring activities in several combinations in the presence of a qualified health
professional BEFORE attempting active use of the wheelchair.
The necessary back angle MUST be selected BEFORE repositioning the rear wheels
forward.
DO NOT operate the tilt function if the trigger release levers and cables are not
properly adjusted. Ensure that the tilt function is locked in place when the trigger
is released.
DO NOT traverse, climb or go down ramps or slopes greater than 9°.
DO NOT leave the occupied wheelchair unattended at any time, especially on an
incline.
DO NOT attempt to reach objects if you have to move forward in the seat.
DO NOT attempt to reach objects if you have to pick them up from the floor by
reaching down between your knees.
DO NOT lean over the top of the back upholstery to reach objects from behind as
this may cause the wheelchair to tip.
DO NOT shift weight or sitting position toward the direction of reach as the
wheelchair may tip.
DO NOT tip the wheelchair about the rear wheel without assistance.
DO NOT use an escalator to move a wheelchair between floors. Serious bodily
injury may occur.
DO NOT attempt to stop a moving wheelchair with the wheel locks. WHEEL
LOCKS ARE NOT BRAKES.
Before attempting to transfer in or out of wheelchair, every precaution should be
taken to reduce the transfer gap distance. Turn both casters towards the object
you are transferring onto. When transferring to and from the wheelchair,
ALWAYS ENGAGE BOTH WHEEL LOCKS.
DO NOT operate the wheelchair on roads, streets or highways.
DO NOT attempt to move up or down an incline that is wet, icy or is covered in an

5SAFETY AND HANDLING OF WHEELCHAIRS
“Safety and Handling” of the wheelchair requires 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 in order to comfortably and
safely navigate in your environment.
Use this information only as a basic guide. The techniques that are discussed on the
following pages have been used successfully by many individuals.
Individual wheelchair users often develop skills to deal with daily living activities that
may differ from those described in this manual. PDG recognizes and encourages each
individual to try what works best in overcoming architectural obstacles that they may
encounter. Techniques in this manual are a starting point for the new wheelchair user
and assistant with “safety” as the most important consideration for all.
5.1 Stability and Balance
To assure stability and proper operation of your wheelchair, you must at all times
maintain proper balance. Your wheelchair has been designed to remain upright and
stable during normal daily activities as long as you do not move your centre of gravity
beyond the boundary of the wheelchair and exceed the balance point.
Virtually all activities which involve movement in the wheelchair have an effect on the
systems center of gravity. Anti-tippers MUST be attached at all times. PDG
recommends using positioning devices 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.

PAGE 8
Class 1 Medical
Rev. 2
PDG DOES NOT recommend the use of this wheelchair for stretching exercises. If
the occupant uses the wheelchair as a stretching exercise apparatus, keep in mind
this will result in changes to the normal balance, the center of gravity and the
weight distribution of the wheelchair and make sure stability and balance are not
compromised.
Coping with Everyday Obstacles
Coping with the irritation of everyday obstacles can be alleviated somewhat by learning
how to manage your wheelchair. Always keep in mind the position of your center of
gravity to maintain stability and balance.
WARNING: DO NOT attempt to perform a “wheelie” in your wheelchair because
of the dangerous nature of this type of maneuver.
A Note to Wheelchair Assistants
When assistance to the wheelchair user is required, remember to use good body
mechanics. Keep your back straight and bend your knees whenever tilting the
wheelchair or traversing curbs, or other obstacles.
Be aware of any removable (detachable) parts. These must NEVER be used for hand-
held or lifting supports, as they may be inadvertently released, resulting in possible
injury to the user and/or assistant(s)
When learning a new technique, have an experienced assistant help before attempting
it alone.
5.2 Tilting
WARNING: DO NOT tilt the wheelchair without assistance.
WARNING: Decreased stability may result from a seat position tilted past 0°
(neutral) or horizontal. Ensure that anti-tippers are used at all times.
When tilting the wheelchair, an assistant should grasp the back of the wheelchair on a
non-removable (non-detachable) part. Inform the wheelchair occupant before tilting
the wheelchair and remind him/her to lean back. Be sure the occupant’s feet and hands
are clear of all wheels and pinch points. In preparation to operate the tilt:
Ensure the occupant’s arms and legs are stable on the armrest and the
footrest/legrest respectively.
Ensure the tilt mechanism is clear of hands, feet or foreign objects.
DO NOT push or propel the chair with the seat tilted in a forward position.
DO NOT add chair accessories that are not specifically designed for the Bentley.
5.3 Curbs and Steps
WARNING: Maneuvering over curbs and steps can be dangerous.
WARNING: DO NOT try to climb or descend a curb or step without assistance. It
may cause your chair to exceed its balance point and tip over.
NEVER attempt to climb or descend a curb or step more than 4” high.
CAUTION: ALWAYS maneuver straight up and down a curb or step. Climbing or
descending at an angle can lead to a fall or tip.
CAUTION: be aware that dropping down from a curb or step can damage your
chair or loosen fasteners.
Use the following procedure to tackle shallow curbs, steps or obstacles:

PAGE 9
Class 1 Medical
Rev. 2
Climbing a curb or single step –Method 1
To climb over a curb or single step have the front of
the wheelchair facing the obstacle and advise your
assistant to stand at the rear of your wheelchair and
apply a continuous downward motion. This will tip the
wheelchair about the rear wheels thereby lifting the
front caster of the ground. As a balance point is
achieved and the front casters clear the curb, instruct
your assistance to roll the wheelchair forward and
slowly lower the front caster to the upper level as they
are beyond the edge of the curb or step. Following,
instruct your assistant to lift and roll the rear wheels
up to the upper level.
Climbing a curb or single step –Method 2
Unless the first assistant has exceptional upper body
strength, it is recommended that METHOD 2 uses two
(2) assistants. The second assistant should be
positioned at the front of the wheelchair lifting upward
on a non-removable (non-detachable) part of the
wheelchair frame when lifting and stabilizing the
wheelchair and when the wheelchair is being lowered
to the ground. The first assistant should stand on the
sidewalk and turn the wheelchair so that the rear
wheels are against the curb. The wheelchair should be
tilted back to the balance point and, in one continuous
downward movement, the rear wheels should be
pulled up and over the curb. DO NOT return the front
casters to the ground until the wheelchair has been
pulled backward far enough for the front casters to
clear the edge of the curb.
Descending a curb or single step
WARNING: NEVER attempt to descend down any curb or obstacle facing forward.
To descend from a curb or a single step, position your
wheelchair so that the front of the wheelchair is facing
away from the curb a couple of meters and ask your
assistant to stand behind your wheelchair. Next,
instruct your assistant to step down the curb and
carefully pull the wheelchair backwards. As the rear
wheels roll over the edge of the curb, allow them to
slowly roll down the rear wheels to the lower level.
Once the rear wheels are safely on the lower level
instruct your assistant to tip the chair about the rear
wheels, lifting the casters off the upper level and
continue to slowly roll the wheelchair backwards
taking small steps until the front casters have cleared
the curb or single step and they can be lowered to the
ground at the lower level.

5.4 Stairways and Escalators
WARNING –DO NOT use an escalator to move a wheelchair between floors. Serious
bodily injury may occur.
WARNING –DO NOT attempt to lift a wheelchair by lifting on any removable
(detachable) parts. Lifting by means of any removable (detachable) parts of a
wheelchair may result in injury to the user or damage to the wheelchair.
Extreme caution is advised when it is necessary to move an occupied wheelchair up or
down the stairs. PDG recommends using two (2) assistants and making thorough
preparations. Make sure to use ONLY secure, non-detachable parts for hand-held
supports.
Follow this procedure for moving the wheelchair
between floors when an elevator is NOT available:
1. After the wheelchair has been tipped back to the
balance point, one assistant (in the rear) backs the
wheelchair up against the first step, while securely
grasping a non-removable (non-detachable) part of
the wheelchair for leverage.
2. The second assistant, with a firm hold on a non-
detachable part of the framework, lifts the
wheelchair up and over the stair and steadies the
wheelchair as the first assistant places one (1) foot on
the next stair and repeats STEP 1.
3. The wheelchair should not be lowered and released
until the last stair has been negotiated and the
wheelchair has been rolled clear of the top of the
stairway.
5.5 Transfers to and from Other Seats
WARNING —before attempting to transfer in or out of
the wheelchair, every precaution should be taken to
reduce transfer gap distance. Turn both casters toward
the object you are transferring onto. Ensure the wheel
locks are engaged to help prevent wheels from moving.
NOTE — this activity may be performed independently
provided you have adequate mobility and upper body
strength.
1. Position the wheelchair as close as possible alongside
the seat to which you are transferring, with the front
casters pointing toward it. Engage wheel locks. Shift
body weight into seat as you transfer.
2. During independent transfer, little or no seat platform
will be beneath you. Use a transfer board if at all
possible.

5.6 Weight Distribution
WARNING –DO NOT attempt to reach objects if you have to move forward in the seat
or pick them up from the floor by reaching down between your knees.
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 health professional
BEFORE attempting active use of the wheelchair.
5.7 Reaching, Leaning, and Bending Forward
Functional Reach from a Wheelchair
Proper positioning is essential for your safety. When
reaching, leaning, bending forward, it is important
to use the front casters as a tool to maintain
stability and balance.
Bending Forward
Position the front casters so that they are extended
as far forward as possible and engage wheel locks.
DO NOT LEAN FORWARD OF THE ARMRESTS.
Bending Backward
WARNING —DO NOT lean over the top of the back upholstery. This will change your
center of gravity and may cause you to tip over.
Reaching Objects on Ground
Position wheelchair as close as possible to the
desired object. Point front casters forward to create
the longest possible wheelbase. Reach back only as
far as your arm will extend without changing your
sitting position.

8UNPACKING AND ASSEMBLY
NOTE – Unless the wheelchair is to be assembled immediately, retain cartons and
packing materials for use in storing the wheelchair until assembly is required
1. Check for any obvious damage to the carton or its contents. If damage is evident,
take pictures of the damages and notify your Dealer/Carrier immediately.
2. Remove all loose packing from the carton.
3. Carefully remove all components from the carton.
8.1 Inspection
Examine exterior of the wheelchair for nicks, dents, scratches or other damage. Inspect
all components. Check the rear wheels for camber. If damage is evident, notify your
Dealer/Carrier immediately.
8.2 Out of the Box Assembly Instructions
When unpacking the wheelchair, you will need to assemble the armrests, backrest, and,
front rigging (if applicable), connect the cable from the strut to the tilt activator (trigger)
and anti-tip tubes to complete the set-up.
Backrest
The seat frame has two bolts installed along the left and right side of the rear of the seat
frame. Remove these bolts on each side and place the backrest subassembly into the
back of the seat frame and replace bolts and fasten securely, see section 14.3. To attach
tilt actuator cable to the back post (trigger) follow instructions in section 14.14.2
Front Rigging
Installing the front rigging depends on the type of front rigging included with chair – For
the Easy-Out front rigging, squeeze the front rigging trigger and slide the front rigging
into the square cross-sections on the side of the upper frame until the latch aligns and
engages with the upper frame hole and snaps into place. For the standard plug-in front
rigging, push in the button on the side of the upper tube and slide into the frame until
snap button engages. For the “swing-away” style front rigging attach the front rigging on
top of the pre-installed mounted adaptor and rotate to lock into place.
Armrest Assembly
Install the arm assembly by simply sliding the arms into the armrest receivers on the
upper frame.
Cable
To install the cable, ensure the lower end of the cable housing is placed in the holes in
the junction block and then install the other end of the cable to the trigger, as usual.
Once the cable is assembled into the trigger, the assembly will be under slight tension,
and the cable housing will stay inserted in the block. Refer to section 14.14 to detailed
instructions.

PAGE 15
Class 1 Medical
Rev. 2
Anti-Tip Tubes
If anti-tip tubes are not already installed on the chair, locate them in the box and slide
them into the receivers at the back underside of the frame so that the rollers are
pointing downwards. These will prevent the chair from overturning if the centre of
gravity moves too far rearward. Anti-tip tubes are mandatory for safety and warranty
protection.
IMPORTANT — with the user sitting in the chair, check to ensure the wheelchair is
stable in all tilted/un-titled positions before dispensing the wheelchair.
9STORAGE
Store the repackaged PDG Wheelchair in a dry area away from sunlight and sources of
heat. Do not place other objects on top of the repackaged wheelchair.
10 SAFETY INSPECTION CHECKLIST
Examine the exterior of the PDG Wheelchair for nicks, dents, scratches, or other
damages. Inspect all components. If damage is evident, notify your Dealer/Carrier
immediately.
NOTE — twice per year take your wheelchair to a qualified dealer for a thorough
inspection and servicing. Regular cleaning will reveal loose or worn parts and enhance
the smooth operation of your wheelchair. To operate properly and safely, your
wheelchair must be cared for in a manner similar to a motor. Routine maintenance will
extend the life and efficiency of your wheelchair.
