L type wrench

Guidelines

• Always wear safety goggles to protect your eyes;
• Wear gloves to protect your hands;
• Always use a wrench proper gauge for each bolt or nut so that there is slack, as this will damage the wrench and screw too.
• When using the key perpendicular to the axis of the screw and / or nut. This increases tool life and makes the operation safer.
• Do not use pipes or other extension rods for more torque. By increasing the distance of the force application increases the torque that can be supplied to the screw, but also runs the risk of breaking the key.
• Do not change the original shape of the keys.
