Using the 3Wrencho is a breeze. When you need to remove a tire from the rim, just insert the lever under the tire bead and gently pry it up. To remove 15mm axle nuts, place the lever on the nut and turn it counter - clockwise. You can even use it to open a bottle when you're done with your bike maintenance. As for stepping on it for extra leverage, make sure you're standing firmly and applying force evenly. When it comes to maintenance, keep it clean after each use. Wipe off any dirt or grease with a dry cloth. Store it in a dry place to prevent rusting. And always be careful not to use too much force that could damage the glass - filled nylon coating.
