Introduction
Thank you for purchasing this Zero Gravity Ultima 4 Trampoline. This trampoline was manufactured
using the highest quality materials and skills gained over decades of trampoline production. If proper care and
maintenance is provided then we’re sure that it will provide years of fun and exercise for the whole family.
We cannot state how important it is for the owners and users of this trampoline to have a thorough
understanding of the rules for proper use. Children must be supervised at all times by a knowledgeable and
mature adult while using the trampoline. When there is to be no adult supervision available then take
precautions to prevent access to the trampoline by children or unauthorized users who do not have your consent
to use the trampoline.
Carefully read and understand all of the instructions and warnings in this guide before assembling and
using this product. It is the responsibility of the owner of this trampoline to ensure that all users of this product
are fully informed on the proper use and the inherent risks of jumping on a trampoline, failure to do so can result
in serious injury or death. In particular, under no circumstances should you attempt or allow flips, somersaults or
any similar behavior. Landing on the head or neck can cause serious injury, paralysis, or death. Never allow
more than one person on the trampoline at any time as this can dramatically increase the risk of injury.
To reduce the risks associated with a user falling off the trampoline, the enclosure netting must be
properly installed and used at all times. The trampoline enclosure must be closed during use to prevent the user
from falling off the trampoline. Although your trampoline enclosure netting is manufactured with UV resistant
material exposure to the elements will weaken the netting over time. Therefore the netting and mattress must be
inspected prior to every use and maintained regularly as detailed in this guide.
Location of the trampoline is extremely important in order to reduce the risk of injury. The intended site
for the trampoline must be completely flat and level. If the ground is not completely flat then it can cause
movement in the frame and put stress on the joint sections which could cause damage to the trampoline and
make it unsafe for use with the risk of causing serious injury. The trampoline must only be located on a soft
surface such as grass or cushion play area. Siting the trampoline on a hard or slippery surface such as paving or
concrete will cause damage to the trampoline and put users at risk. The trampoline must be clear from overhead
hazards such as power cables and tree limbs with at least 8 metres overhead clearance from ground level. Site
the trampoline at least 2.5 metres away from any structure or obstacle.
The trampoline must never be used in windy conditions as this can cause unexpected movement of the
product. Wind can cause the trampoline to be lifted from the ground and become airborne presenting a danger
to individuals and to property. We always recommend that you anchor or secure the trampoline to prevent it
from moving as a result of the wind. We highly recommend consulting a local licensed tradesman to best
determine how to implement an anchor system for your specific conditions. Even with anchors in place a
trampoline can be lifted by strong winds. If high winds are forecast the trampoline should be disassembled and
stored away safely until the weather conditions improve. Damage from the wind or other severe weather is not
covered by the manufacturer’s warranty.
Only genuine Zero Gravity replacement parts sold through an authorized dealer should be used.
Replacement parts produced by any other manufacturer may not have met the design and extensive safety
testing standards used in the production of this Zero Gravity trampoline. As a result of this Zero Gravity
Trampolines will not guarantee the performance and safety of the product when non genuine replacement parts
are used. The use of non-genuine Zero Gravity replacement parts may affect any warranty claim on the product,
as allowed by the law in your jurisdiction.

When choosing the location for your trampoline please ensure that the area is completely flat and level.
The trampoline should be clear from obstructions overhead, we recommend 8 metres clearance from
ground level. Ensure that there is a minimum of 2 metres clearance from any structure or obstruction
around the edge of the trampoline. There should be no obstructions underneath the trampoline and it is
preferable to select a well lit area.
Two adults are required to erect the trampoline
We recommend wearing heavy duty work gloves and eye protection when assembling the trampoline.
The trampoline has passed extensive safety testing, do not modify the design of the product in any way
nor use non-original Zero Gravity parts.
The packaging does contain some small parts which are a choking hazard for small children. It is
therefore recommended that children under the age of 3 years should be kept away when the trampoline
is being assembled.
Ensure that you keep this instruction manual for reference in the future.
Before using the trampoline
Use of this trampoline requires constant adult supervision. Use the trampoline only with mature and
knowledgeable ADULT supervision.

Important Safety Instructions
Only one user at any one time! Multiple users can cause loss of control, collision or falls on the
trampoline. This could result in serious injury to legs, arms, back, neck or head.
Do not use the trampoline when under the influence of alcohol, drugs or medication, which may impair
the jumper’s judgement.
Always consult your physician before performing any kind of physical activity.
Do not use the trampoline if you have high blood pressure.
Do not use the trampoline if you have a medical history of neck or back injuries or mental or physical
conditions that could cause injury.
Do not use if the user has any broken bones (casts) or has recently been in the hospital for extensive
treatments (operations, severe wounds, stitches, back injury or concussion).
If pregnant do not use without the consent of your physician.
Do not use the trampoline if the user or the trampoline surface is wet. These conditions can cause the
user to lose control and fall resulting in serious injury.
The product must not be used in windy conditions as wind can cause unexpected movement of the
product. Wind can cause the trampoline to be lifted off the ground and become airborne. This can
present a danger to individuals and to property. Winds can be especially strong in open areas, areas
between homes that create wind tunnels and anywhere else where local weather conditions can create
high winds. We recommend that you anchor the trampoline or otherwise secure the trampoline to
prevent it from moving as a result of the wind. One possible way to anchor the trampoline is to secure
the trampoline to a concrete footing under each leg. We recommend consulting a local licensed
contractor to best determine how the anchor system should be constructed for your specific conditions.
When anchoring the trampoline straps must always be connected to the top ring of the trampoline, not
the feet as legs could be separated from the main frame in strong winds. Even with anchors, a
trampoline can be lifted, just like anything else, by strong winds. If the winds are anticipated to be very
strong, the trampoline should be disassembled and stored away safely until the weather conditions
improve. Damage from the wind or other severe weather is not covered by the manufacturer’s warranty.
Because the manufacturer warranty does not cover wind or weather related damage and damage can
be caused to your property or the property of others by a windblown trampoline, it is strongly advised
that you provide site specific anchoring through a licensed local contractor.
Use trampoline only with mature, knowledgeable adult supervision.
Do not attempt or allow somersaults. Landing on the head or neck can cause serious injury, paralysis, or
death, even when landing in the middle of the mat.
Do not allow more than one person on the trampoline. Use by more than one person at the same time
increases the chance of injury.
Carefully read these warnings before using this product. Failure to follow these warnings
can result in serious injury or death. 

Proper Play Conditions:
Always use the product in a well-lit area. Do not use without lighting during dawn, dusk or in complete
darkness.
The trampoline must be placed on a surface that is COMPLETELY FLAT AND LEVEL. If the ground
is uneven, this could cause movement in the frame and could cause stress on the joined sections of
the frame that could damage the trampoline and/or can cause serious injury.
DO NOT install or position this trampoline on a hard surface such as concrete, tarmac or paving.
Suitable surfaces are grass, sand or a play area covered with an appropriate depth of play bark
material.
ALWAYS ensure the trampoline is on level ground with a minimum of 8.2ft ( 2.5 metres ) clear space
from any structure or obstruction such as fence, garage, house, overhanging branches, laundry lines or
electrical wires.

recommended. Provide clearance for wires, tree limbs, and other possible hazards.
Do not use the trampoline indoors, as this product is intended for outdoor home use only.
Appropriate Use Conditions:
Children must always be supervised while they are playing on the trampoline and must be instructed
not to use the trampoline in an inappropriate or hazardous manner. Take precautions to prevent
access to the trampoline by children when there is no adult supervision.
Restrict access to the trampoline by any unauthorized users without your consent.
Trampolines are rebounding devices, which propel the user to unaccustomed heights, and into a
variety of body movements. Rebounding off of the trampoline, striking the frame or springs, or
improperly landing on the trampoline mat may cause serious injury.
Always start and maintain your jump at the center of the trampoline mat in order to reduce the risk of
landing on the frame or springs or falling off the trampoline. When you land more than 1ft away from
the edge of the Zero Gravity logo in the centre of the mat stop your jump immediately. Restart your
jump at the centre of the mat.
Avoid bouncing too high. Stay low until you can control your bounce and land consistently in the
middle of the trampoline mat.
Ensure the trampoline frame and springs are fully covered by the frame pad to avoid any direct contact
with metal parts.

The trampoline is several feet off the ground. Jumping off the trampoline to the ground or any other
surface may result in injury. Smaller children may need assistance getting up onto or down from the
trampoline. Mounting and dismounting properly should be followed as a strict rule. Users should climb
onto the trampoline by placing their hands on the frame and stepping or rolling up onto the frame,
across the springs and onto the mat. Do not step directly on the frame pad or grasp the frame pad
when mounting or dismounting the trampoline. To dismount, jumpers should walk to the side of the
mat, bend over and place their hands on the frame, then step from the mat to the ground. Users
should always place their hands on the frame while mounting or dismounting.

During winter period, the snow load and the very low temperature can damage the trampoline. It is
recommended to remove the snow and store the mat and the enclosure indoors.
Do not jump or step onto the frame pad as it was not designed to support the weight of a person.
Do not use the trampoline while holding or wearing any type of sharp or pointed objects such as
jewelry, watches, rings, eyewear and necklaces before using this product. This will prevent the jewelry
from tearing the mat or getting caught in the enclosure netting.
Do not wear loose fitting clothing that may catch or snag during play.
Never wear footwear (e.g. shoes) when using the trampoline.
Always tie back long hair so that it does not block user’s vision or get caught in the enclosure netting.
FRAME PADS –Frame pads are there to protect user from any fall or landing on the springs and frame.
On no account should people be permitted to sit or stand on them when the trampoline is in use. You
should also make sure that smaller users do not use the inside edges of the pads as a “handle” when
getting up on to the trampoline.
Never use the trampoline without the frame pad being securely attached. Properly tie down the frame
pad before each use. Improper assembly of the frame pad may lead to injury.
Always check to ensure there are no obstructions or objects under the trampoline that could cause
injury or obstruct movement of jump mat. Also check that there are no pets or other people underneath
the trampoline.
