6. Maintenance
To ensure the longevity and optimal performance of your KROAK Creeper Seat, follow these maintenance guidelines:
- Cleaning: The nano-sealed polymer leather surface is designed to repel oil, water, and grime. Wipe spills and dirt immediately with a clean, damp cloth. Avoid abrasive cleaners or solvents that could damage the material.
- Wheel Inspection: Periodically check the wheels for any signs of wear, damage, or debris accumulation. Clean the wheels and ensure they rotate freely. Verify that the wheel fasteners remain tight.
- Frame Inspection: Regularly inspect the steel frame for any signs of bending, cracks, or corrosion. Ensure all bolts and nuts are securely tightened.
- Storage: Store the creeper in a dry, clean environment when not in use to prevent rust and material degradation.

7. Troubleshooting
This section addresses common issues you might encounter with your KROAK 4-in-1 Z Creeper Seat.
- Issue: Creeper does not roll smoothly.
Solution: Check the wheels for debris (e.g., dirt, hair, small objects) that might be obstructing their movement. Clean the wheels and their axles. Ensure the wheel bolts are not overtightened, which can restrict rotation. - Issue: Creeper feels unstable or wobbly.
Solution: Verify that all frame connections and wheel fasteners are securely tightened. Refer to the assembly instructions (Section 4) to ensure all components are correctly installed and locked into place for the chosen configuration. Do not exceed the stated weight capacity. - Issue: Difficulty converting between modes.
Solution: Ensure that no weight is on the creeper when attempting to convert its configuration. Check for any obstructions in the hinge mechanisms. Apply a small amount of silicone-based lubricant to the hinges if they are stiff.
