Springs; Pads - Urban Air Pro Zone Operation & Maintenance Manual

wear and tear issues, take a well-lit photo of the defected area (hole or abrasion, etc.) and email it to us
for review. Abrasion (non-holes) should be viewed more critically for older jumping mats, as jumping
mat fabric weakens over time.
At the beginning of a business day, every jumping mat should be thoroughly inspected before users
begin jumping (and replace any mats that show holes or excessive wear). This inspection can occur at
the end of the prior operating day if it is assured that the trampoline will remained unused until the next
day.
Be sure to ensure redundant/secondary jumping mats are recycled and re-installed during the
installation of new jumping mats. (See cleaning instructions below) Redundant mats should not be relied
on as the primary safety mechanism for users. User injury can occur during the splitting of a jumping
mat, or even without the user touching the concrete floor. Therefore, a sound redundant mat is not a
reason for delaying the replacement of primary mats with holes or excessive abrasion. Patron injury can
occur during the splitting of a jumping mat, even without the patron touching the concrete floor. Every
week the maintenance team should inspect under the courts/jumping mats for any damage. It is highly
recommend-ed to close the court before accessing its underside. If the court cannot be closed, close off
a section with a monitor above blocking users from jumping into the area being serviced.
Anyone servicing an open court should remain directly under the frame and should never go under a
trampoline.

3.2 Springs

Springs should be replaced when they fail either of these tests:
1. The spring's body or hook is visually deformed. This can be inspected during weekly inspections under
the trampoline floors and behind the trampoline walls.
2. When a spring is removed, clench the base in one hand and shake it. After doing this to several
springs you will notice a slight variance in their coil strength. All springs that are moderately or very
weak should be replaced. Failure to replace deformed or weak springs forces neighboring springs to
bear more load and cause them to prematurely fail. Weak springs will inevitably cause more weak
springs. Every week springs should be visually inspected from under the trampoline or behind the angled
walls. When jumping mats are replaced, every spring should be removed and individually tested using
method #2 cited above.
3. Some extra springs are encouraged for emergency replacement.

3.3 Pads

Foam inside the pads will become compressed over time and will then require replacement. The
expected lifespan of the foam inside PVC vinyl sleeves is at least one year for most safety pads. The
