Virtufit Trampoline with Safety Net
8
Missing parts: If you think you are missing certain parts in your package, carefully check the styrofoa and
the trampoline. Some parts (bolts, screws, etc.) are already attached to/in the trampoline.
Use gloves to protect your hands from bottlenecks during assembly. When you’re ready to get started,
make sure you have plenty of room and a clean, dry area for mounting.
Read the assembly instructions below before you start mounting the trampoline. Incorrect mounting
will damage the trampoline frame:
β€’ Make sure the trampoline is placed on level ground. Uneven ground surfaces may cause the
trampoline frame to warp (FIG 1).
β€’ Make sure that all bolts holding the frame joints are tightened completely before installing the
springs. Failure to do this properly will cause the frame to warp.
β€’ Make sure NOT to use one’s leg to push against the trampoline leg or frame when loading the springs.
It will cause the trampoline to warp (FIG 2).
β€’ DO NOT load the springs onto the frame on only one side of the trampoline. Uneven distribution of
tension from the springs will cause the frame to warp (FIG 2).
β€’ If the trampoline frame warps up, do not be alarmed as the β€œQuad-lock” system is designed to be
flexible. Push down on the part of the frame that warped with two people as shown. The frame will
level out (FIG 3).
NOTE! For the next assembly 2 adults in good physical condition are required. Wear good shoes and
keep balance to avoid a fall. Failure to follow all instructions and warnings exactly could result in
serious injury.
