Trampolines are fun for almost all age groups, and are designed for either single or multiple users. Hedstrom trampolines are made using a strong tubular frame and a large piece of synthetic canvas connected to the frame using either spring coils or elastic cord, which produces a strong bouncing movement when jumped upon. Hedstrom trampolines are easy to set up as well as disassemble; the only tools required are an adjustable wrench and an Allen wrench both of which are usually supplied with the device depending on the Hedstrom model selected.
Assemble the base of the trampoline by taking the four leg sections and bolting them together in a rectangular pattern. Hold two of the legs together at a 90-degree angle. Make sure the bolt holes on both legs fit nicely together to ensure that the bolt can slide through with ease. Slide the bolts through making sure a washer is also inserted on both sides of the bolt. Use an adjustable wrench and Allen key to loosely secure the bolts and legs together. Repeat this assembly procedure for the remaining three legs, so that the four legs form a rectangular base. Leave the bolts loose.
Assemble the handle of the trampoline by taking the two handle riser poles and insert them into the tubular handle. You may have to press the spring clips together to make the riser poles slide onto the handle tube without binding. Release the spring clips once they are connected. Make sure the tubular tube is in the middle of both the handle riser poles and that the legs of the handle (riser tubes) are facing the ground.
Take the handle risers and position them against two legs that are still loosely connected. Remove the bolts securing these two legs, then position the riser tube from each end of the handle between these legs so that all the holes align properly. Reinsert the connecting bolts and tighten them securely. Make sure a washer is still on both sides of the bolt. Tighten all bolts securely using an adjustable wrench and an Allen wrench until the frame and handle assemblies are all tight.
Take the elastic cord and the mat that came with the trampoline and lay them across the trampoline frame. Insert one end of the elastic cord into one of the eyelets on the very corner of the mat. Pull the cord through the first eyelet hole and wrap it diagonally down over the bar of the leg base and pull it back under the leg to the opposite side. Now wrap the cord back over the top of the new leg base and pull it diagonally to the opposite side eyelet hole to the one that has been threaded and thread the cord through. Even out the cord to make sure there is equal length on both sides.
Thread one end of the cord through the remaining eyelets in the mat by pulling the cord in an under, through eyelet, over movement. Once you have threaded two of the eyelet holes, change the sequence to threading the cord through the top of the mat instead of the bottom when pulling it under the leg frame. When the corner of the mat and legs are reached, continue to loop around the corner and repeat the threading movement in the same fashion. This will ensure that the mat will be taught when finished. Continue to thread the cord until the entire mat has been attached to the frame.
Tie off the ends of the elastic cord once it has been threaded. Check the mat to make sure it is perfectly aligned in the centre of the trampoline frame without much gap between the mat and the frame on any side. Push a plastic sleeve over end of the cord. Take a hook from the plastic sleeve and thread it through the eyelet on the other end of the cord. Wrap the cord around the leg twice for safety. Hook the other end of the hook to the other eyelet on the other side of the cord making sure the hook is underneath the frame. Slip the sleeve over the top of the hook for added protection.
