Cleaning
Periodic cleaning of all surfaces will help keep your wheelchair looking good and operating properly. All
surfaces can be cleaned using warm water and a mild soap solution. Do not use abrasive cleaners on any
surfaces.
Suggested Maintenance Procedures
1 Before using your PDG Elevation, make sure all nuts and bolts are tight. Check all parts for damage or
wear and replace. Check all parts for proper adjustment.
2. Keep quick-release axles, free of dirt and lint to ensure positive locking and proper operation. Refer to
Rear-Wheel Axle Nut Adjustment in this manual.
3 If applicable, oil quick-release axles at least once (1) a month (3-in-1 oil or equivalent).
Warning
— If pneumatic tires are used, do not use the wheelchair unless it has the proper tire pressure.
DO NOT over inflate the tires. Failure to follow these suggestions may cause the tire to explode and
cause bodily harm.
4 If tires are pneumatic, recommended tire pressure is listed on the side wall of the tire. Please refer to
Table 12.1 for the size options of the tires and tubes and their corresponding pressures.
5. The wheels and tires should be checked periodically for cracks and wear, and should be replaced
when necessary at your authorized Dealer or by a qualified technician.
6 For wheelchairs with handrims, periodically check handrims to ensure they are secured to the rear
wheels.
19 SET UP & ADJUSTMENTS
Rear Wheel Removal and Installation
Quick-release axles come standard on the Elevation. They
will allow the rear wheels to be easily removed and installed.
To install wheel
1 Depress quick-release button fully.
2 Insert axle through hub of rear wheel.
3 Keep the button depressed as the axle is slid through the
axle receiver on the frame. (See Figure 19.1)
4 Release button to lock axle into the receiver. Adjust
the nut on the axle if it does not lock or if there is play
between the wheel and axle receiver. (See “Rear Wheel
Axle Nut Adjustment.”)
To remove wheel
1 Depress quick-release button fully.
2 With button depressed simultaneously pull back on the
center of the wheel.

Warning
— Do not use this chair UNLESS you are sure both quick-release axles are locked. An unlocked
axle may come off during use and cause a fall.
Rear Wheel Axle Nut Adjustment
The quick-release axle attaches the rear wheel to the axle receiver. When the axle is fully inserted into
both the wheel and axle receiver the detent balls will lock the wheel assembly in place. By pushing the
button on the quick-release axle the detent balls will be disengaged and wheel can be removed. If wheel
and axle will not lock or alternatively if it is locking into place but there is excessive play when the wheel
hub is pushing back and forth, the nut on the axle needs to be adjusted.
If the axle does not lock
1 Using a 7/16” open end wrench, securely hold the detent ball end
of the axle. (See Figure 19.2)
2 Use the ¾” open-end wrench to turn the axle nut counter-
clockwise.
3 Turn the nut approximately in ½ turn increments
4 Try to lock the axle into the axle receiver.
5 If it doesn’t lock, repeat steps 3 and 4 until it locks securely.
If the axle locks, but there is excessive play
1 Using a 7/16” open end wrench, securely hold the detent ball end
of the axle. (See Figure 19.2)
2 Use the ¾” open-end wrench to turn the axle nut clockwise.
3 Turn the nut approximately in ½ turn increments.
4 Insert the axle and test for play.
5 Repeat steps 3 and 4 until the play has be eliminated and the detent balls are fully extended.
Seat Height
The minimum seat height adjustment setting of the Elevation is preset at the factory for the user to
achieve the most commonly used range of seat heights. However, minor adjustments may be required
to optimize an occupant’s unique requirements and comfort. Increasing the minimum seat height will
decrease the distance the seat will go down and increase the maximum distance the seat will go up.
To adjust minimum height
1 Using the 5mm Allen key, remove the socket head cap screws on the
upper frame crossbar, as shown. (See Figure 19.3)
2 Slide the upper frame crossbar toward the front of the wheelchair to
increase the minimum height.
3 Alternatively slide the upper frame crossbar rearward to decrease the
minimum height.
4 Ensure the indexing features are equidistant from the backrest,
on each side, to ensure proper functioning of the seat height
mechanism.
5 Refit and tighten the cap screws once set.
