5. Operating Instructions
5.1 Loading the Wagon
- Utilize the two-tier design to organize your items. The upper deck is suitable for general items, while the lower deck, especially when extended, is perfect for longer or bulkier gear.
- Place heavier items on the bottom deck and distribute weight evenly to maintain balance and stability during transport.
- Secure loose items with straps or nets if necessary to prevent them from shifting or falling out.

5.3 Using the Brakes
The wagon is equipped with a built-in dual braking system for secure parking.
- To engage the brakes, press down on the brake levers located near the wheels.
- Ensure both brakes are fully engaged to prevent the wagon from rolling, especially on inclines.
- To release the brakes, lift the levers upwards.
5.4 Folding the Wagon for Storage
To fold the wagon for compact storage:
- Ensure the wagon is empty.
- Locate the pull strap or handle in the center of the wagon's base.
- Pull the strap upwards firmly. The wagon frame will begin to collapse inwards.
- Continue pulling until the wagon is fully folded into its compact size.
- Secure the folded wagon with any integrated straps or clips to prevent it from unfolding during transport or storage.
6. Maintenance
- Cleaning: The Oxford fabric and PVC components can be cleaned with a damp cloth and mild soap. Avoid harsh chemicals or abrasive cleaners. Allow to air dry completely before folding and storing.
- Wheels: Periodically check the wheels for debris, such as mud or tangled grass, and clean as needed to ensure smooth operation.
- Frame: Inspect the carbon steel frame for any signs of rust or damage. Wipe down with a dry cloth after use, especially if exposed to moisture.
- Storage: Store the folded wagon in a dry, cool place, away from direct sunlight and extreme temperatures, to prolong its lifespan.
7. Troubleshooting
- Wagon not unfolding/folding smoothly: Ensure no fabric is caught in the frame mechanism. Check that the central pull strap is fully engaged when folding.
- Wheels not turning freely: Inspect wheels for debris or obstructions. Ensure brakes are fully disengaged.
- Wagon feels unstable: Verify that the load is within the 500 lbs weight limit and distributed evenly. Ensure the frame is fully locked into its open position.
- Brakes not holding: Check if the brake levers are fully pressed down. Inspect the brake mechanism for any damage or wear.
