Introduction 1
Congratulations on purchasing a JumpSport Safety Enclosure! We sincerely believe that you have purchased the finest
safety enclosure on the market. It has been engineered with safety, durability, and performance in mind.
Safe use of a trampoline also requires adequate knowledge of technique, as well as what not to do. Please read this
manual thoroughly for key points of safety.
Trampolines, being rebounding devices, propel the performer to unaccustomed heights and into a variety of body
movements. Therefore, it is emphasized that all purchasers, and all persons using the trampoline, become familiar with
the rules for safe use. Misuse and abuse of this trampoline is dangerous, and can cause serious injuries. The purchaser/
user of this piece of equipment is assuming a degree of risk for which JumpSport cannot be responsible.
Read this information thoroughly before allowing the trampoline to be used. Keep this manual available for your
review, and for review by all potential users. If there are questions please call JumpSport for further explanation.
Caution
Many users of our trampolines are children, and therefore need close supervision and rules to follow while playing on
the trampoline. These rules must be enforced by whomever is responsible for the care of the children. It is strongly
recommended that the buyer of this product go over the rules and recommendations in the packet of information
supplied, including those in this manual. It is also strongly recommended that these rules and recommendations be
supplemented with those of your own, for example: the time that jumping is allowed, when neighbors can visit, and so
on. These rules and recommendations should be reviewed with anyone who is going to jump on the trampoline. If it is
possible, review these rules with the parents or guardians of any visitors who may be jumping on the trampoline. See
Safety Rules (under the Use Instructions section) for more information.

Assembly and Installation
Instructions 2
Preparation
Before you begin assembling your JumpSport Safety Enclosure, make sure your trampoline is in a proper location.
Trampoline Placement
Caution: When deciding on where to place your trampoline, consider the following:
WARNING
Overhead Clearance Adequate overhead clearance is essential. A minimum of 24 feet from ground level
is recommended. Provide clearance for wires, tree limbs, and other possible hazards.
Lateral Clearance Lateral clearance is essential. Place the trampoline and trampoline enclosure away from
walls, structures, fences, and other play areas. Maintain a clear space on all sides of the
trampoline and trampoline enclosure.
Level Surface Place the trampoline and trampoline enclosure on a level surface before use.
Lighting Use the trampoline and trampoline enclosure in a well-lighted area. Artificial
illumination may be required for indoor or shady areas.
Security Secure the trampoline and trampoline enclosure against unauthorized and
unsupervised use.
Ground Clearance Remove any obstructions from beneath the trampoline and trampoline enclosure.
Note: The trampoline enclosure is only to be used as an enclosure for a trampoline of a size for which the enclosure
is designed.
Note: The owner and supervisors of the trampoline are responsible to make all users aware of practices specified in
the Use Instructions.
IMPORTANT: The best surface on which to place your trampoline is dirt or grass. However, if you plan to install the
trampoline on a very hard surface such as concrete or asphalt, a dense foam —similar to what can be found in
public playgrounds —should be installed under each leg. Contact JumpSport Customer Service if you have any
questions.
It is the responsibility of the purchaser to become familiar with all of the information in this booklet, to
convey the warnings to all users, and to enforce JumpSport’s rules for safe use.
This unit is not intended for commercial or public use, and such use is strictly prohibited.
The maximum user weight is up to: 200 pounds (Model 280), 230 pounds (Models 120 & 380), 295
pounds (Models 480 & 480XT), or the specified user weight rating of your trampoline—whichever is low-
er.

Assembly and Installation Instructions
Tools
Installation of the safety enclosure requires a 13mm socket wrench (included), or a deep socket with a ratchet or elec-
tric drill. An 8ft A-Frame ladder will be useful for some steps (use care and follow procedures for use). Safety glasses
and gloves are also recommended for safety.
Parts List
Your JumpSport Safety Enclosure is shipped with the parts shown below. Some parts will be located in a smaller inner
box. If any parts are missing, immediately call JumpSport Customer Service at 408-213-2551.
Note: Do NOT discard the foam tubing (Reference #3 and #4); it is needed to make the pole assemblies. It is not
just packing material. Not all poles will have foam around them. And do NOT remove any caps from the ends of any
of the support poles.

Assembly
Note: We recommend at least 2 people participate in assembling the safety enclosure. Use page 8 to help with part
names and numbers.
1) Build all pole assemblies as shown. Pole sleeve and foam will fit tightly up inside ball end cap, and notch in ball end cap will fit
inside notched end of upper pole. See page 8 for detailed part descriptions.

3) Tighten the two nuts evenly, using the hand wrench (# 14). Make sure that the carriage bolt does not spin by making sure the
head is fully seated in the square hole on the enclosure pole. Nuts are snug when the poles are firmly attached to the trampoline leg
with no movement. It is OK if the wings on the spacers begin to yield.
IMPORTANT: Be sure nothing is
caught between pole and leg
(including pole sleeve, foam
tubing, frame pad, etc.) before
tightening the bolts.

2) Using the hardware provided, connect a pole to the outside of each trampoline leg:
 Line up bottom of the enclosure pole with the existing trampoline leg so both holes match, and the square holes on the enclosure
pole face out, and indents at hole face toward the frame.
 Insert bolt #7 through the square enclosure pole hole and through pole spacer #9 at both locations on the enclosure pole.
 Insert the bolts through the trampoline leg holes.
 Insert nut #8 through the trampoline leg and at both locations, and hand-tighten.
Make sure indent-
ed dimples on
enclosure poles
face IN, toward the
trampoline frame.
Verify that holes on
frame are aligned, and
that the indented hole
on vertical leg faces
OUT (if applicable).

4) Familiarize yourself with the net. The net has a wider strap at the top of the net. There are red marks on the top and bottom straps
of net to help with installation. The red marks on the top strap should line up with the ball end cap at the top of each pole. The red
marks on the bottom strap should line up with the outside of each pole.
Note: Red marks are a guide to help speed installation. If you find that the red marks don't line up perfectly, then be sure that pole
1 is above a right vertical leg piece, as shown in the diagram in Step 5. If they still do not line up, please disregard them and be
sure that the net is pulled snugly from the top of one pole to the next.
If you have a different company’s trampoline, the red marks may not line up at all.
If you have a Model 480XT, there will not be any red marks at all.
