- Distribute items evenly across the shelf surface.
- The 2-inch deep tub-style shelves help prevent items from falling off during movement.
- Do not exceed the individual shelf capacity of 133 lbs or the total cart capacity of 400 lbs.
4.2 Moving the Cart
- Ensure the two locking casters are disengaged before moving.
- Grasp the ergonomic flat handle firmly.
- The 360° swivel wheels allow for easy maneuverability in any direction.
- Push or pull the cart smoothly, avoiding sudden stops or turns, especially when heavily loaded.

4.3 Locking the Cart
- Once the cart is in the desired position, engage the locks on the two rear wheels.
- Press down on the locking lever of each wheel until it clicks into place.
- Verify that the cart is stable and cannot move before leaving it unattended.
5. Maintenance
Regular maintenance will extend the life and performance of your IRONMAX utility cart.
- Cleaning: The cart features a premium powder coating that is rust-resistant and easy to clean. Wipe down surfaces with a damp cloth and mild detergent as needed. Avoid abrasive cleaners.
- Fastener Check: Periodically inspect all bolts, nuts, and screws to ensure they are tight. Re-tighten any loose fasteners to maintain structural integrity.
- Wheel Inspection: Check the casters for any debris (e.g., hair, string) that might hinder smooth rotation. Clean as necessary. Lubricate wheel axles if they become stiff.
- Storage: Store the cart in a dry environment to prevent potential rust, although the coating offers good protection.

6. Troubleshooting
If you encounter issues with your utility cart, refer to the following common problems and solutions.
- Cart is unstable or wobbly:
Solution: Check all assembly bolts and nuts to ensure they are securely tightened. Ensure the cart is on a flat, level surface. Redistribute the load evenly, placing heavier items on lower shelves. - Wheels are difficult to roll:
Solution: Inspect wheels for debris (e.g., dirt, hair) caught in the axles or treads. Clean any obstructions. If necessary, apply a small amount of lubricant to the wheel axles. Ensure wheel locks are disengaged. - Wheel locks are not holding:
Solution: Check if the locking mechanism is fully engaged. Ensure the wheels are clean and free of oil or grease that might reduce friction. If the mechanism is damaged, contact customer support. - Items falling off shelves:
Solution: Ensure items are placed within the 2-inch deep tub-style shelves. Avoid overloading shelves. Move the cart at a slower, more controlled pace.
