Using these P handle hand trucks is easy. First, place the load on the nose plate of the truck. Make sure the load is balanced and secure. Then, hold the 'P' shaped handle with one or both hands and tilt the truck back to lift the load off the ground. You can now easily steer and move the load to your desired location. When it comes to safety, always check the weight capacity of the truck before loading. Do not exceed the maximum capacity as it can lead to instability and potential accidents. Avoid sharp turns at high speeds with heavy loads. For maintenance, regularly check the wheels for any signs of wear and tear. Clean the truck after use, especially if it has been exposed to dirt or debris. If the truck is made of steel or stainless steel, keep an eye out for rust and treat it promptly. For aluminum models, protect them from scratches to maintain their appearance.
