Things You'll Need
Instructions
Ensure your swing set is located on level ground. If it is lopsided in any way, the set is much more likely to tip. The ground should also be firm without much give to it.
Check the frame of the swing set to verify the screws are completely tight and there is no wobble anywhere there shouldn't be. Screws come loose over time so the set should be inspected weekly to make sure everything is tight.
Hammer metal spikes into the dirt to create the holes that the swing set anchors will be screwed into. The holes need to align with the legs in the swing set, which should already have holes in them to accommodate anchors.
Thread the anchors through the legs of the swing set and twist them in with a straight rod all the way until they penetrate the ground. Most swing sets come with anchors designed for that particular set. You can otherwise get them from a hardware store.
Cover the heads of the anchors with foam or protective rubber to help prevent injury hazards.
