Operating Your Stroller Wagon
Pushing and Pulling
The adjustable push handle allows for comfortable maneuvering. An optional pull strap is included for easier navigation on soft terrain.
Engaging Brakes
To engage the brakes, press down firmly on the foot brake lever located near the rear wheels. Ensure both wheels are locked before leaving the wagon unattended.
Adjusting the Canopy
The canopy can be slid along the poles to adjust its position or removed entirely for open-air use.
Utilizing the Front Zipper Door
The front zipper door provides easy access for children to enter and exit the wagon independently. It also facilitates loading and unloading items.
Utility Mode
For increased storage space, the bench seats can be removed, transforming the stroller wagon into a deep carriage basket suitable for carrying gear, groceries, or other items.
