Using this slab dolly is easy. First, place the slab gently on the dolly, making sure it's centered. The rubber channel will keep it safe. Then, you can start moving it around. Use the swivel caster to change directions easily. When you need to stop, apply the heavy - duty locking brake. Remember, don't overload the dolly as it may affect its performance. For maintenance, regularly check the pressurized wheels for proper inflation. Also, clean the rubber channel to keep it in good condition. This will ensure your dolly lasts a long time and keeps working well.
