Using your Jet bolt cutter is easy. First, identify the material you want to cut, like bolts or chains. Make sure the material's hardness is within the cutter's limit of HRC - 40. Place the material between the black center - cut jaws. Then, grip the 42 - inch rubber - covered handles firmly. Apply pressure to the handles, leveraging the angled design for maximum cutting power. When you're done using the cutter, clean it with a dry cloth to remove any debris. Store it in a dry place to prevent rust. Avoid using the cutter on materials harder than its specified limit as it can damage the jaws. Also, don't drop the cutter or subject it to excessive force as this can affect its performance and durability.
