Any modifications made by the consumer to the original trampoline (e.g. the adding of an accessory) shall be carried out according to the instructions of the manufacturer.
TRAMPOLINE PLACEMENT
Adequate overhead clearance is essential. A minimum of 24 ft from ground level is recommended. Provide clearance from wires, tree limbs, and other possible hazards. Maintain a clear space on all sides of the trampoline and enclosure. Place the trampoline and enclosure away from walls, structures, fences, and other play areas. Install the trampoline on a level surface before use.
Use the trampoline and trampoline enclosure in a well-lit area. Artificial illumination may be required for indoor or shady areas. Secure the trampoline and enclosure against unauthorized and unsupervised use. Remove any obstructions from beneath the trampoline. The owner and supervisors of the trampoline are responsible for making all users aware of the practices specified in the use instructions. The enclosure is only to be used for the trampoline for which it is designed.
PARTS LIST
Adjust the trampoline’s firmness by using fewer or more extension hooks 
- DO NOT dig before assembling springs and jump mat. The frame contracts and dimensions are altered.
- Place the frame with the mat and springs installed on the intended location and mark out 4in outside the frame.
- Remove the frame and dig the hole according to the dimensions in the diagram. Failure to do so may cause serious injury. Use the sewn belt assembly and the 2 hooks to measure the depth of the hole.
- It is a good idea to cover the area around the hole to save time and effort when restoring the lawn after the installation.
- Dig the 6in shelf straight and level as the trampoline needs a solid and level surface to rest on.
- Make sure to keep soil and grass to backfill the 4in area around the trampoline when it is installed.
| Model | X dim | Y dim |
| 10×6 | 9’9” | 6’2” |
| 12×8 | 11’10” | 8’ |
| 15×10 | 15’4” | 10’2” |
| 17×12 | 17’4” | 12’ |
- Dig the hole to the full depth as close to the edge of the hole as possible. Failure to do so may result in serious injury. Use the table to determine the correct depth for your trampoline.
- Build a soak-away to drain water: Dig a hole, 2ft diameter and 2ft deep. Line the hole with permeable weed membrane (available at DIY stores). Fill with shingle or crushed hardcore. Wrap the membrane over the top of the hardcore/shingle. Lay some slabs to seal the top.
- Add a permeable weed membrane to the hole before putting in the trampoline. Make sure the membrane sits right at the bottom of the hole – keeping clear of the jump area.
- Check that he levels are correct. Adjust the height that the frame is sitting on. Aim for the trampoline bed to sit flush with the ground.
- Fit the foam pieces into the padding and attach the hooks to the elastic straps on the short sides and the corners.
- Connect the upper and lower part of the safety net poles. Make sure that all the spring clips are locked into position to keep the poles securely connected. Make sure the poles are properly fitted with foam.
- Insert the poles into the sleeves in the net. Make sure the poles are covered with foam all the way up inside the sleeves.
- Insert the poles into the frame sockets through the slots in the padding.
- Now you should be done! Check that all instructions have been followed and that all parts are securely fastened in the correct positions. If you are unsure please contact us for further guidance.
CARE & MAINTENANCE
INSPECTION
Inspect the trampoline and trampoline enclosure before each use and replace any worn, defective, or missing parts. The following conditions could represent potential hazards:
- Missing, improperly positioned, or insecurely attached frame padding, barrier or enclosure support system padding and pole caps.
- Punctures, frays, tears, or holes worn in the bed or frame padding, the barrier or support system padding.
- Deterioration in the stitching or fabric of the bed or frame padding, barrier or support system padding.
- Ruptured springs,
- A bent or broken frame or enclosure support system.
- A sagging bed or barrier
- Sharp protrusions on the frame, suspension system or enclosure support system.
Note that sunlight, rain, snow, and extreme temperatures reduce the strength of these parts over time. If the above checks are not carried out, the trampoline could become dangerous. Make sure to replace defective or missing parts. To order original North Trampoline spare parts, please contact your local dealer. If any parts of the trampoline are exchanged or updated, they should be installed according to the assembly manual of the trampoline. The new or added parts may have their own instructions for attachment and correct installation. Be sure to carefully follow these instructions and apply them accordingly. Check all coverings of bolts for sharp edges and replace them if necessary. If self-locking nuts are used, it should be noted that these are suitable for only one assembly and must be replaced for reassembly.
CLEANING
When cleaning the jump mat be sure to first remove the debris with a broom. Use a garden hose and cold water to clean any remaining dirt. The padding can be wiped with mild detergent to remove dirt from seams and pockets. Make sure to clean the padding from any detergent residue. The trampoline can dry naturally in the sun.
STORAGE
During the winter season, the soft parts of the trampoline, such as the foam pad, should be kept at room temperature and away from moisture. To avoid mold, make sure to dry the soft parts thoroughly before storage. Preferably, all metal parts should be stored inside for longer durability. In strong wind conditions, always remove the safety net to prevent damage. To disassemble the trampoline, follow the assembly manual in reverse. If you have room, keep the poles still in the net. This will save you some time for the next assembly. Use gloves to protect your hands from injury during disassembly. Replace the safety net after 3 years. Retain these instructions for continued care and maintenance.
WARNING
DO NOT attempt or allow somersaults on the trampoline. Landing on the head or neck can cause serious injury, paralysis, or death, even when landing in the middle of the bed. Do not allow more than one person on the trampoline inside the trampoline enclosure. Use by more than one person at the same time can result in serious injuries. Use the trampoline and enclosure only with mature, knowledgeable supervision. Trampolines over 20 in. (51 cm) tall are not recommended for use by children under 6 years of age. Inspect the trampoline and enclosure before each use. Make sure the frame padding, barrier, and the enclosure support system padding are correctly and securely positioned. Replace any worn, defective, or missing parts. Climb on and off the trampoline. It is a dangerous practice to jump from the trampoline to the floor or ground when dismounting, or to jump onto the trampoline when mounting. Do not use the trampoline as a springboard to other objects. Stop bouncing by flexing your knees as your feet come in contact with the trampoline bed. Learn this skill before attempting others. Learn fundamental bounces and body positions thoroughly before trying more advanced skills. A variety of trampoline activities can be carried out by performing the basic fundamentals in various series and combinations, performing one fundamental after another, with or without feet bounces between them.
Avoid bouncing too high. Stay low until bounce control and repeated landing in the center of the trampoline can be accomplished. Control is more important than height. While keeping the head erect, focus eyes on the trampoline toward the perimeter. This will help control bounce. Avoid bouncing when tired. Keep turns short. Properly secure the trampoline when not in use. Protect it against unauthorized use. If a trampoline ladder is used, the supervisor should remove it from the trampoline when leaving the area to prevent unsupervised access by children under 6 years of age. Do not use or stand near the trampoline in windy or gusty conditions. A trampoline can become airborne when exposed to sustained wind or gusting wind conditions. This can result in serious injury, paralysis, or death, as well as property damage. To reduce these risks, disassemble the trampoline and enclosure and store them until weather conditions improve. Anchoring a trampoline frame may prevent the trampoline from moving as a result of the wind, but even anchored trampolines can become airborne or damaged. Consult a qualified contractor to determine what type of anchor works best in your location. Keep objects away that could interfere with the performer. Maintain a clear area around the trampoline.Do not use the trampoline while under the influence of alcohol or drugs. For additional information concerning the trampoline equipment, contact the manufacturer. For information concerning skill training, contact a certified trampoline instructor.
Bounce only when the surface of the bed is dry. Wind or air movement should be calm to gentle. The trampoline must not be used in gusty or severe winds. Users may become entangled in or strangled by loose cords or in gaps between the trampoline and the enclosure. Keep the enclosure tightly fastened to the trampoline in accordance with the manufacturer’s instructions. Failure to properly assemble and maintain a tight, secure trampoline/ enclosure boundary may result in serious injury, strangulation, or death. Do not attempt to jump over the barrier. Do not attempt to crawl under the barrier. Do not intentionally rebound off the barrier.Do not hang from, kick, cut, or climb on the barrier. Wear clothing free of drawstrings, hooks, loops or anything that could get caught while using the trampoline/enclosure and result in entanglement or strangulation, or both. Do not attach anything to the barrier that is not a manufacturer-approved accessory or part of the enclosure system. Enter and exit the enclosure only at the enclosure door or barrier opening designated for that purpose. Read all instructions before using the trampoline and enclosure. Warnings and instructions for the care, maintenance, and use of this trampoline and enclosure are included to promote safe, enjoyable use of this equipment.
EXERCISES & TRICKS
Learn fundamental jumps and body positions thoroughly before trying more advanced tricks.
Note: To stop bouncing bend your knees when your feet touch the mat. Practice this technique so that you may stop safely if you lose control or land outside of the centre of the trampoline.
BASIC JUMP
Stand with your feet slightly apart in the middle of the trampoline and keep your body stretched. Keep your legs together when bouncing and extend your feet. Land properly on the soles of your feet, with your feet slightly apart. Firmly push off your feet when you jump up from the trampoline. Stretch up your body and swing your arms upwards and forwards. Part your feet and bend your knees when you land, use your arms to maintain your balance.
TUCK JUMP
Begin in the same way as for a basic jump. Bend your knees towards your chest and place your arms gently around your legs at the highest point of the jump. Release your legs and stretch out your body before you reach the mat again. Land with your body stretched and your arms by your sides.
STRADDLE JUMP 
Begin in the same way as for a basic jump. Bend your body at the hips with your legs straight at the highest point of the jump. Part your legs as much as you can with your feet extended, and try to touch the top of your feet at the highest point of the jump. Land with your body stretched and your arms by your sides.
SEAT DROP 
Start by practicing the landing position without bouncing. Sit in the center of the trampoline with legs together, back straight, and hands slightly behind you, fingers forward. Practice landing from standing to a seat drop without bouncing, then with a small bounce. To stand up, push your hips forward and press down with your hands. Always aim to land in the center of the trampoline and on your feet in the middle of the mat.
