Assembling the Wheelchair

Connecting the lower rear crossbar (B) to the left and right side arm assembly (A)

  1. Insert big hex wrench (L-1) in bolt on the right wheel connector (B) of right side arm assembly (A).
  2. On the opposite side of right wheel connector (B), insert nut in small wrench (L-3). Unscrew and remove nut and bolt entirely.
  3. Insert one end of the lower rear crossbar (B) in the hole of right wheel connector (A). Make sure that the wheel bolt is facing in the opposite direction of the lower rear crossbar (B).
  4. Make sure that the hole on lower rear crossbar (B) is aligned to the hole on right wheel connector (A).
  5. Re-insert bolt in hole until it comes out the other side.
  6. Re-insert nut and turn using big hex wrench (L-1) and small wrench (L-3) until secure but do not tighten.
  7. Repeat 1.1. to 1.6 to install the other end of the lower rear crossbar (B) in the hole of left wheel connector.

Connecting the upper rear crossbar (C) to the left and right side arm assembly (A)

  1. On the upper crossbar connector of the right side arm assembly (A), insert nut in small wrench (L-3).
  2. On the opposite side of upper crossbar connector (A), insert big hex wrench (L-1) in bolt. Unscrew and remove entirely.
  3. Insert one end of the upper rear crossbar (C) in the hole of the upper crossbar connectors (A). Make sure that the upper rear crossbar (C) is parallel with the lower rear crossbar.
  4. Make sure that the hole on upper rear crossbar (C) is aligned to the hole on upper crossbar connectors (A).
  5. Re-insert bolt in hole until it comes out the other side.
  6. Re-insert nut and turn using big hex wrench (L-1) and small wrench (L-3) until secure but do not tighten.
  7. Hold the other end of the upper rear crossbar and pull towards the direction of the hole on the upper crossbar connector on the left side arm assembly (A).
  8. Insert the end into the hole as soon as it is aligned.
  9. Re-insert bolt in hole until it comes out the other side. It may take some jiggling pulling and pushing of the bars to align the holes to allow the bolt to pass thru.
  10. Re-insert nut and turn using big hex wrench (L-1) and small wrench (L-3) until secure. You may now tighten all the nuts and bolts of both upper (C) and lower rear crossbars (B).

Notes on Measurements

Once you have assembled your pet’s new wheelchair, you can use the measuring guide below to give it a customized fit. We always strive to keep things simple. The following are the key measurements you need to take to ensure a comfortable ride for your pet. Please remember to use a rigid tape measure. If your pet has difficulty standing or staying upright, get someone to help either support your pet or do the measuring.

A. Rear leg height, from floor all the way to the backbone (top of the pelvis)

B. Body length

C. Hip width—straight across

D. Floor to groin height

Further Notes on Measurement

  1. The rear leg height measurements (A and D) are to ensure that the wheelchair is set so that your dog’s body is properly supported. When set at the correct height, your pet can use what movement and strength it has in its legs—allowing your pet some traction (instead of pawing air). If your pet has no hind leg strength, use the leg straps to prevent paw dragging.
  2. The hip width measurement (C) will help you get the right setting for the crossbars. The right width setting will prevent painful chafing that can occur in improperly set wheelchairs, where your pet’s body may end up repeatedly rubbing against the metal frame.
Tips
  • The front side arms should be approximately 2 inches below the top of your pet’s shoulders.
  • The rear side arms should be approximately 2 inches below the top of your pet’s hip.
  • The two side arms of the wheelchair’s frame should be parallel to your pet’s back
  • Your pet’s sides should be approximately 1 inch away from the side arms.
  • Your pet’s sides should not rub against the side arms while your pet is walking.
  • The front harness should rest snugly but comfortably under your pet’s forelegs.
  • The front strap should sit slightly above the center of the chest.
  • The front strap must not press against the throat.
  • The front strap must not rest below the center of the chest.
  • DO NOT LEAVE YOUR PET ALONE IN THE WHEELCHAIR
Because these wheelchairs are adjustable in all three dimensions, it is important to get your pet fitted properly. Setting the height, length, and width will be your task. You might get it right on the first try or a bit of fine-tuning might be required. Please keep in mind that although some pets are able to ambulate in the chair on their first time, it is much more likely to take several sessions before your pet is able to use the wheelchair with assistance, and even longer without.
Please be patient and remember that this is a learning process.

Using the Quad/Full Support Wheelchair

It is usually best to attach a leash to the front bar to help with the training, and to help give the dog cues and assistance in moving the chair. Please note that if the dog has not ambulated in some time, they will not be able to push a full support chair on their own, they will require some exercise first. You must assist them with pushing the chair for several sessions before they can build the strength to walk and run in the quad chair unassisted.

Care & Maintenance

Keep the wheelchair clean. Your pet will surely appreciate it and ride with pride. Wipe down aluminum surfaces with warm, soapy water using a soft cloth such as a microfiber or cotton rag. Rinse and dry.

Check the bolts and screws frequently; re-tighten if loose. Adjust or tighten loose straps as well.

Remember to hose or wipe down tires to keep them from tracking dirt. Check tire pressure every so often and inflate when needed. To reduce bounce and increase traction, lessen tire pressure (to just under 35 PSI) to give the wheelchair a more comfortable ride.

Wash the sling, harness, and straps in cool, soapy water and hang them to dry. Opting for a perfume-free detergent will help your pet avoid skin irritation. You may want to try odor neutralizers (homemade or store-bought) to counter any smell that may remain in the harness.
