Hold down the button and slide the handles to adjust the jaw opening. Do not touch your finger on the backside of the button when pressing.
Why does the new pliers have oil on it? It looks like dirt.
The oil you see on the new pliers is a rust-preventive oil, not dirt. It is applied to protect the metal parts during shipping and storage, preventing corrosion. When you use the pliers, you can wipe off any excess oil with a clean cloth.
Does "4-inch pliers" mean the jaw opens to 4 inches?
No. The "4-inch" refers to the overall length of the pliers, not the jaw opening. The actual max opening is typically around 13/16 inch.
Why is the mini pliers wrench so small?
The 4-inch mini wrench pliers are designed for tight spaces. Made of high-strength steel with a parallel jaw, it delivers big performance in a small size—Compact and lightweight for everyday carry.
How should I clean and maintain my pliers?
After use, wipe the pliers clean and dry, then coat with oil to prevent rust. Regularly check for damage and replace worn parts. Store in a dry, clean place, away from moisture and extreme temperatures.
