2. Wheel Camber
The wheel camber adjustment provides
greater side-to-side stability due to the
increased width and angle of the wheelbase.
The wheel camber adjustment also allows
for quicker turning and greater access to
the top of the handrims.
Wheel camber is determined by the axle
tube. Tubes are available from your autho-
rized supplier in 0º, 4º and 8º angles.
3. Toe-in or Toe-out
Toe-in and Toe-out are terms that relate to
how well the rear wheels of the chair are
aligned.This will affect how well the chair
will roll. Drag or resistance occurs in a
wheelchair when the rear wheels are not
properly aligned.
Toe-in or toe-out can be slightly adjusted
by rotating both eccentric axle sleeves
equally, fore or aft.
4. Wheelbase Width Adjustment
Adjusting the wheelbase width allows the
rider the option to move the wheels clos-
er or further away from the hips. It also
compensates for camber adjustment and
gives the proper wheel spacing to maxi-
mize pushing efficiency.
Adjust the wheelbase width by loosening
the nut and repositioning the axle sleeve (A)
into its corresponding hole. Retighten nuts.

5. Rear Wheel Axle Sleeve Adjustment
Tight axle sleeves should be maintained for
proper performance of the wheelchair.
To adjust the axle you will need a 3/4"
wrench to turn the outside axle nuts. You
will also need a 1/2" wrench to lodge the
ball bearings, on the opposite end of the
axle, and prevent the axle from turning.
Turn the outside axle nut counter clock-
wise to tighten. There should only be zero
to ten thousandths of an inch (.010) of play.

1. Angle Adjustment
Note: setting the wheelchair on a flat surface table
or a workbench, helps make these procedures easier.
Note on Torque Setting: A torque setting is the
optimum tightening which should be made on a
particular fastener. A torque wrench which mea-
sures in./lbs. Should be used when tightening fas-
teners on Quickie wheelchairs. Unless otherwise
noted, use a torque setting of 60 in.-lbs.When set-
ting up this wheelchair.
