Assembling the Wheelchair

1. Connecting the upper rear crossbar (B) to the side arm assemblies (A)

1.2 Fit the upper rear crossbar (B) to the left side arm assembly (A).

1.3 Place the connector block screw and the clip connector screw together inside the upper crossbar connector block

1.4 Hold the connector block screw steady with an open-end wrench while securing the clip connector screw with a hex wrench.

1.5 Repeat steps 1.1 to 1.3 to connect the upper rear crossbar to the right side arm assembly

 

2. Connecting the lower rear crossbar (C) to the side arm assemblies (A)  

2.1 Fit the lower rear crossbar (C) to the left and right side arm assemblies (A).

2.2 Place the connector block screw and the clip connector screw together inside the clip connector.

 

 

2.3 Hold the connector block screw steady with an open-end wrench while securing the clip connector screw with a hex wrench.

2.4 Using an open-end wrench and a hex wrench, tighten connector block screws for upper rear crossbar (B) and lower rear crossbar (C) to secure connection to the side arm assemblies (A).

3. Installing the left and right front harness bars (D)

3.1 Insert the left front harness bar (D) to the left side arm (A).

3.2 Adjust to desired length. Make sure the holes on the left front harness bar (D) are aligned with the holes on the left side arm assembly (A).

 

3.3 Insert metal lock in aligned hole until it comes out the other side. 3.4 Repeat 3.1 to 3.3 to install the right front harness bar (D) to the right side arm assembly (A).

 

Below: Your progress so far.

Figure 1. Please note that the upper rear crossbar is shorter than the lower rear crossbar; this makes the lower portion of the cart wider than the top.

4. Attaching the left and right wheels (E)

4.1 Use the big open-end wrench (I) to unscrew the wheel bolt from the right wheel connector found on the lower right arm assembly (A).

 

4.2 Insert a metal washer thru the bolt then insert thru the wheel hole. Insert another metal washer thru the bolt on the other side of the wheel.

4.3 Screw the bolt back to the right wheel connector on the right side arm assembly (A). 

Tighten using the big open-end wrench (I).

4.4 Inflate wheels to recommended 35 psi, if necessary, with any standard pump.

5. Connecting the rear harness (F)

 

 

5.1 Align each plastic O-connector clamp near a corresponding side arm bolt. Holding it by the plastic ring, position strap with O-connector clamp to go up and over the side arm assembly.

 5.2 Fasten O-connector clamp to the side arm bolt by pushing it upward.

 

5.3 Repeat steps 5.1 to 5.2 to connect the remaining clamps. 

 

5.4 Adjust the rear harness straps to a comfortable weight- bearing position for your pet. Make it longer or shorter using the adjuster buckle.  

6. Attaching the front harness (G)

6.1 Attach the front harness (G) to the front harness bar simply by connecting the side release buckles.

6.2 Adjust front harness straps for snug yet com fortable fit using the ad juster buckle.

7.  Attaching the leg straps (H)

7.1 Clip the leg straps (H) to the metal eyelets on the upper rear crossbar.

Video Instructions (optional)

Wheelchair Use:

If your pet’s hind legs are completely non-weight bearing and will need the use of the leg straps, the forelegs will require some conditioning time; it will need additional strength in order to compensate for weight the hind legs and for added comfort while in the. Please allow about two weeks for full strengthening of the forelegs before using the pet wheelchair for prolonged periods.

Again, to develop foreleg strength, we recommend 10-minute exercise sessions, with your pet walking over a hard surface. Begin with two 10-minute exercise sessions a day for the first few days and go up to three times daily afterwards. When your pet adapts to the 10-minute exercise sessions, you can extend the time to conform to your pet’s stamina.

Is your pet is too weak to stay on its forelegs while in the wheelchair due to being inactive or overweight? Attaching a leash on your pet’s collar or to the wheelchair’s front harness will help encourage your pet to walk or move and eventually work up to completing the conditioning regimen.

If your pet’s forelegs do not display enough strength within a few weeks, it may need something other than what our wheelchair can provide. Observe if your pet is always trying to lie down or is still unable to hold its own weight after a couple of weeks. These are signs that its forelegs aren’t strong enough—and not improving—to use a wheelchair. 

Your pet may initially move backward instead of forward once in the wheelchair. No need to worry. Your pet is “backing out” due to unfamiliarity. He or she will eventually settle down, become familiar and comfortable, and start moving forward with some assurance and encouragement.

Get your pet and its wheelchair wet! Our wheelchairs are made mostly of aluminum and will not rust. If the wheelchair is used at the beach and in salt water, just give it a thorough rinse to get the sand, salt water, and dirt off the moving parts; otherwise, getting the unit wet will not damage it.

If the wheel traction of your pet’s wheelchair is poor, you may want to check the tire pressure. Remember to keep the pressure slightly below the required PSI. Make sure that the wheels can spin freely.

If the wheels track to one side more than the other, it may simply be due to how your pet naturally walks. You may notice your pet’s gait more due to the new wheelchair, however, he or she will get used to the Rear Support wheelchair and be able to compensate in due time. Also, check both sides to make sure that your pet is centered on the wheelchair and adjust the straps if necessary.

 

To adjust wheelchair length:

  1. Loosen socket set screws on the top portion of the side arm connector.
  2. Adjust length by pulling or pushing the side arm.
  3. Repeat on other side arm. Make sure to align both sides.
  4. Tighten socket set screws.

NOTE: Check the length of the wheelchair’s side arms. While your pet is standing still and with its forelegs legs straight, the side arms should end right behind the forelegs or up to the point of shoulder.

To adjust wheelchair width:

  1. Loosen and remove sucker button head cap screws on the rear harness bar using the hex wrench.
  2. Move the rear harness bars to desired width. Make sure that at least two holes on the right rear harness bar are aligned to two holes on the left rear harness bar.
  3. Return socket button head cap screws on aligned holes and tighten with the hex wrench.

To adjust the rear harness:

  1. Loosen the hex screw located at the bottom of the side arm connector.
  2. Push in the attached black cables to loosen the rear harness or pull in to make it tighter.
  3. Re-tighten the screws

 

 

Troubleshooting and Resolving Common Challenges

The wheelchair tips forward.

  • Make sure that the frame’s side arm height is a couple of inches below your pet’s back. Adjust the side arm height by lowering or raising frame height through the side arm connector and wheel assemblies.
  • Check the front harness. Make sure that it is centered across your pet’s chest. Adjust the straps and see if this keeps the wheel chair from tipping.
Your pet loses breath while moving using wheelchair.
  •  Check the front harness. If it is positioned too high, it will press against your pet’s throat when walking. Adjust front harness height so that your pet can breathe freely especially while moving.
Pet’s hind legs not comfortably resting on the rear harness and harness does not extend beyond pet’s rear
  • The angle of the harness is too high. Adjust harness height so that your pet’s legs are at a comfortable and natural height.
Your pet takes shorter strides.
  • A too low front harness is the usual culprit. Adjust height so as not to hamper your pet’s natural stride.
The wheelchair’s side arm bars are pointing downward.
  • Your straps may not be evenly distributed.
  1. Loosen the lower girth strap (red strap)
  2. Tighten the top girth strap enough to hold the side arm bars parallel to the ground.
  3. Re-tighten the lower girth strap enough so that both straps are snug but comfortable.
The wheelchair’s side arm bars are pointing upward.
  • Same problem as above, uneven distribution of the straps this time favoring the opposite side.
  1. Loosen the top girth strap.
  2. Tighten the lower girth strap (red strap) to pull the side arm bars down parallel to the ground.
  3. Re-tighten top girth strap. Make sure both straps are snug but comfortable.
