REAR AXLE AND ANTITIP RECEIVER SUBASSEMBLY
ADJUSTMENT
Seat Height and Rear
Axle Adjustment
The wheelchair can
accommodate two seat
heights, 17” and 18.5”. The
seat height adjustment
will be completed in four
independent areas of the
chair: Rear-wheel-and-axle,
Caster-fork, Anti-tipper, and
Wheel-lock.
Note — If adjusting seat
height, all four areas of the
chair will be modied. If
adjusting wheel-base then
caster-fork position will
remain untouched.
The xed Rear Wheel Axle
location may be located in
four positions. In each case
the axle is bolted directly
to the side frame of the
wheelchair. To move the
rear axle, use the following
procedure.
CRITCAL NOTE — When you alter the position of the rear wheel you MUST also ret the wheel-lock and
anti-tipper. Failure to do so will result in non-functional anti-tip and wheel-lock systems.
Removal
Remove the rear-wheel-and-axle assembly from the side frame using a 17mm open end wrench to retain
the axle and a 19mm wrench or socket to remove the axle retention lock nut.
Ret
Select which of the rear axle positions is desired, t rear-wheel-and-axle assembly using tools as indicated
above.
Note — It may be necessary to loosen and/or remove the wheel-lock before retting the rear-wheel-and-
axle assembly.
SAFETY SUMMARY (continued)
Tire Pressure for Pneumatic Tires
6 DO NOT use the wheelchair unless it has the proper tire ination pressure. DO NOT over inate the
tires. Failure to follow these suggestions may cause the tire to explode and cause bodily harm.
4 Replacement of a pneumatic tire or tube MUST be performed by an authorized PDG Dealer or
Qualied Technician.
Weight Training
6 DO NOT use PDG wheel chairs during weight training activities. They have not been designed or
tested for this type of activity. Use of a wheel chair during weight training immediately voids the
warranty. PDG shall not be liable for any injury or wheel chair damage as a result.
Weight Limit
The Maximum user weight is 400lbs or 182kg as shown on the product order form. The product selection
process should be done with the activity level of individual wheelchair users in mind. For example, a
270 lb. active wheelchair user could subject the wheelchair to more stress than a 400lb passive user. The
Manufacturer recommends that very active heavy-duty users consider the use of an extra heavy-duty
construction type PDG wheel chair.

page 12 page 5
Foot Rests
Attach hanger brackets to bracket receptacles on the wheelchair.
1 Adjustment is made to with a user seated in the wheelchair with both feet on the foot plates. Use a
wrench and a hex head driver to loosen or tighten the bolts on the slide tubes of foot plates.
2 Remove the hex head bolt and the tube clamp and slide foot rest tube up or down until the desired
length is reached. Reassemble the hex head bolt into the tube clamp and into the threaded clamp
insert. The lowest point of the foot plates should be no less than 2-1/2” from the ground or oor.
NOTE — Check that the foot rest adjustment does not cause pressure to the back of the users legs at front
of seat upholstery. Such a condition could cause injury to the occupant.
WARNING — DO NOT ATTEMPT TO STAND ON FOOT PLATES. Standing on the foot plates will cause the
chair to tip forward and may cause personal injury.
WARNING — DO NOT ATTEMPT to lift the chair by foot rests or leg rests. FOOT PLATES SHOULD BE in an
upright position and swung out of the way when entering or exiting the wheelchair.
SAFE HANDLING OF WHEELCHAIRS
METHOD 1 - Wheelchair With Step Tubes
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 dierence in the weight distribution.
Roll the wheelchair forward and slowly lower the wheelchair in
one continuous movement. Do not let the wheelchair drop the
last few inches to the ground. This could result in injury to the
occupant. Push the wheelchair forward until the rear wheels
roll up and over the curb.
METHOD 2 - Wheelchairs without Step Tubes
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. The rst 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
upward 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.
STAIRWAYS
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 necessary to move an occupied wheelchair up or down 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 when an
elevator is NOT available:
1 After the wheelchair has been tilted back to the balance
point, one assistant (in the rear) backs the wheelchair
up against the rst step, while securely grasping a non-
removable (non-detachable) part of the wheelchair for
leverage.
2 The second assistant, with a rm hold on a non-detachable
part of the framework, lifts the wheelchair up and over the
stair and steadies the wheelchair as the rst assistant places
one (1) foot on the next stair and repeats STEP 1.
3 The wheelchair should not be lowered until the last stair has been negotiated and the wheelchair has
been rolled away from the stairway.

OPERATION AND SAFETY
Removable Arm
To Swing Back & Remove Arm/Adjust Armrest Height
The armrest release lever is located on the side of the chair on the back of the arm support tube. To
unlock the arm, move the armrest release lever in a forward direction, approximately 1/2”. The front of the
armrest can then swing up and out of the engaged / locked position.
To replace and lock armrest, swing the armrest horizontally until it lays parallel with the side frame of
the wheelchair then swing it vertically until it locks into position Lift the armrest without activating the
release lever to check that the arm is in a locked position.
Wheel Locks
Activate the wheel locks by pushing the handle forward. To adjust locks,
loosen the bolts and nuts that pass through the mounting bracket and
frame. Slide the clamp toward the rear wheel until the wheel lock shoe is
embedded into the tire material approximately by 1/8” when handle is
engaged to the locked position. Re-tighten bolt and nut to secure
mounting bracket in the desired location. Inspect for correct locking
action BEFORE actual use. If the lock becomes worn or damaged, replace
the entire assembly immediately.
CAUTION — WHEEL LOCK IS NOT A BRAKE. DO NOT attempt to stop a
moving wheelchair with wheel locks. When leaving or entering chair,
ALWAYS ENGAGE BOTH WHEEL LOCKS.
WARNING — Inspect wheel locks regularly to check that they are in proper adjustment
ESCALATORS
6 DO NOTuse an escalator to move a wheelchair between oors. Serious bodily injury may occur.
TRANSFERRING TO AND FROM OTHER SEATS
WARNING — BEFORE attempting to transfer in or out of the
wheelchair, every precaution should be taken to reduce the
gap distance between the wheel chair and the object you are
transferring onto. Turn both casters toward the object you are
transferring onto. Engage the wheel locks to prevent the rear
wheels from moving. Shift your body weight from the seat to
the object you are transferring on to.
CAUTION — When transferring, position yourself as far back
as possible in the seat. This will prevent both damage to
the upholstery and the possibility of the wheelchair tipping
forward.
NOTE — This activity may be performed independently provided you have adequate mobility and upper
body strength.
During independent transfer, little or no seat platform will be beneath you. Use a transfer board if
possible.
PERCENTAGE OF WEIGHT DISTRIBUTION
WARNING — DO NOT attempt to reach objects if you have to
move forward in the seat or pick them up from the oor 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 qualied health 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 to maintain stability and balance.
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.
The approximate reach-limit values shown in the
accompanying graph were derived on the basis of a sample
of 91 male and 36 female subject wheelchair users. Note the
dierence between the maximum and the comfortable reach
limits, a subjective but important consideration in design.
