What safety practice should be followed when using adjustable wrenches?

When using adjustable wrenches, it is important to push or pull the handle away from the adjustable jaw because this technique enhances stability and control while applying force. Pulling the handle toward the adjustable jaw can lead to increased risk of slippage and can compromise grip, making it less effective and potentially causing injury. By pushing or pulling away, you maintain a secure hold on the wrench and minimize the chance of the tool slipping off the fastener, which can lead to damaging the fittings or injuring yourself. This practice also helps to ensure that the wrench remains positioned correctly on the fitting, allowing for better torque application without risking injury or tool failure.
