Seat Sling, Rear Axles | Sunrise Medical Quickie 2 Lite instruction

J. SEAT SLING

The seat sling can be adjusted through the use of hook and loop material beneath the seat. Seat sling also includes a folding strap on the seat to assist in folding the chair. 16 NOTE– The seat sling folding strap is not intended as a carrying strap.

Adjustment 16

a.Remove seat rail end caps at the front of the chair (A).

b.Slide the seat sling, plastic retaining rods, and spacers (if present) from the channels in the seat rails.

c.Readjust hook and loop material to obtain the desired tension in the seat sling.

d.Reinsert the seat sling and plastic retaining rods into the channels in the seat rails.

L. REAR AXLES

The most important adjustment on your Quickie wheelchair is the position of the rear axle. The center of gravity, wheel camber and wheelbase are all determined by the axle adjustment.

Use a torque setting of 100 in.-lbs. when adjusting rear axle.

WARNING

The more you move your rear wheels forward, the more likely your chair will tip over backwards. Always make adjustments in small increments, and check the sta- bility of your chair with a spotter to prevent a tip-over. We recommend that you use anti-tip tubes until you adapt to the change and are sure you are not at risk to tip over. Refer to additional Warnings in Section VI “Falls and Tip-Overs”.

NOTE– Adjusting your chair’s center of gravity will require re-adjsuting the location of the wheel locks (if provided). See Section Q for instructions on adjusting the wheel locks.

1. Center of Gravity 17

Moving the center of gravity to the front will lighten the force required to turn the chair. The further back the axle, the more stable the chair becomes.

a.Remove four retaining bolts (B), nuts and camber spacers on axle plate (C).

b.Move axle plate forward or rearward to desired position.

c.Insert all four bolts and camber spacers back into place on frame. Tighten nuts.

d.Repeat on opposite side of wheelchair.

e.Axle plate and camber must be exactly the same on both sides of the wheelchair.

2. Wheel Camber 18

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.

More or less camber can be obtained by increasing or decreasing the number of camber spacers (D) located between the lower axle plate attachment (E) and frame (F).

3. Wheel Base Width Adjustment

Adjusting the wheelbase width allows the rider the option to move the wheels closer 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: 19

a.Loosen the nuts (G) and reposition the axle sleeve (H) to the desired width.

b.Retighten nuts.
