(Make sure the line indicators on the side extenders still face outward on each side.)
7. Reinstall the knuckle by placing half of it over the bolt. Make sure the arrow is pointing to front of the wheelchair,
teeth on the outside.

9. Insert the rear strut in knuckle at correct height for your dog.

NOTE: You won’t be using the front harness that came with the rear kit. Instead you will use the Leg Rings that
came with the front wheel kit for the front support.
On top of the caster wheels you will see the letter ”R” or “L”. The “R” is for the dog’s right leg, and the “L” is for the
dog’s le leg.

Installing the FRONT Wheels to the Frame (see Diagram 1)
1. Remove the adjustment knob and washer on the front knuckle, holding the bonded knuckle together in one
piece, remove bolt. Attach knuckle to the side extender over the slot approximately 3” from the front end.
The front knuckle is bonded together. This should insure the correct angle for caster mount and wheel.
(caster mount top should always be parallel to ground).
2. Insert bolt through the side extender and knuckle, then install the front wheel angle piece in the slanted slot,
add flat washer and adjustment knob, screw on tightly.
Note: you might need to move the outer strut down to get to the adjustment knob. (Continued on page 3)
