Using these transport cart wheels is a breeze. First, make sure your Weha cart is on a flat surface. Slide the wheels up into the granite A - frame base receivers. Once installed, you can easily move your A - frame cart around the shop. When moving heavy loads, don't exceed the 2,000 lbs weight capacity to avoid damaging the wheels. For maintenance, regularly check the wheels for any signs of wear and tear. Clean the wheels with a mild soap and water solution to keep them rolling smoothly. If you notice any issues with the swivel or fixed casters, replace them promptly to ensure the continued performance of your cart.
