Insert the front and rear wheels into their respective slots on the stroller frame until they click securely into place. The front wheels are universal and shock-absorbed, while the rear wheels are lockable and directional. - Attaching the Pet Carrier:
Align the removable pet carrier with the mounting points on the stroller frame. Press down firmly until the carrier is securely attached. Ensure the bottom plate inside the carrier is properly adjusted and flat to provide a stable base for your pet. - Adjusting the Canopy:

- Frame Care: Wipe the metal frame with a damp cloth as needed. Avoid prolonged exposure to moisture to prevent rust.
- Wheel Maintenance: Periodically check wheels for debris and ensure they spin freely. Lubricate axles if necessary.
- Storage: When not in use, fold the stroller into its compact size (31"L x 19"W x 9"H) and secure it with the hook. Store in a dry, cool place away from direct sunlight.

- Stroller does not fold or unfold smoothly: Check for any obstructions in the folding mechanism. Ensure the button is fully depressed when attempting to fold.
- Wheels are stiff or do not roll properly: Inspect wheels for tangled hair, dirt, or debris. Clean as necessary. Ensure wheels are correctly installed and locked into place.
