Operating Instructions
Expanding Capacity
The MTR4080 bag offers expandable capacity from 60L to 80L.
- Locate the expansion zippers on both sides of the bag.
- Unzip these zippers to extend the bag's volume.
- Zip them back up to return to the compact 60L size.

Using Compartments and Features
- Side Pockets: Utilize the large zippered side pockets for easy storage and access to frequently needed items. These pockets contain multiple compartments for organization.
- Elastic Band: The elastic band on top of the bag is suitable for carrying or hanging lightweight items.
- Shoulder Strap: Attach the included shoulder strap to convert the bag into a duffel bag for off-bike carrying.
- Rain Cover: In adverse weather, deploy the rain cover. It features a drawstring to ensure it stays in place even in windy conditions.

Maintenance
- Cleaning: Wipe the bag with a damp cloth and mild soap. Do not use harsh chemicals or abrasive cleaners.
- Drying: Allow the bag to air dry completely before storage to prevent mold or mildew.
- Storage: When not in use, fold the bag for compact storage.
- Zipper Care: Periodically clean zippers and apply a silicone-based lubricant to ensure smooth operation.

Troubleshooting
- Loose Straps: If straps loosen during riding, ensure the lock-down buckles are fully engaged and tightened. Re-adjust and secure all straps before each ride.
- Zipper Issues: If zippers become stiff, clean them and apply a small amount of zipper lubricant. Avoid forcing stuck zippers.
- Bag Deforming: The bag's main frame is supported by reinforced steel wire and PE board to maintain shape. Ensure heavy items are placed at the bottom and weight is distributed evenly.
- Water Leakage: While the bag is waterproof, ensure the rain cover is properly fitted and all zippers are fully closed during heavy rain.
