 F. The Harnesses 
The harness is the actual link between the jumper and the COMBO, as it straps the jumper to the elastics 
system. To safely utilize the COMBO, both the jumper and the instructor need to fully understand 
proper 
Harness fitting, adjusting, and positioning techniques. There are 3 sizes of harnesses: Small (S), 
Medium (M), and Large (L). The jumper should be fitted in a tight-fitting harness; the jumper should 
wear the smallest size he/she fits. Getting a proper size is very important for both safety and comfort. 
There is also now a one size fits all harness that is acceptable for use. SHOULD THE 
CIRCUMFERENCE OF THE JUMPER’S HIPS BE TOO SMALL TO ALLOW THE 
COMPLETE TIGHTENING OF THE HARNESS WAIST-STRAP IN A SECURE MANNER, 
DO NOT USE THE COMBO. FAILURE TO MAINTAIN A SECURE WAIST WITHIN THE 
HARNESS WILL RESULT IN AN UNSAFE CONDITION. 
 
The following is proper harness fitting procedure: 
- The jumper is to stand in front of the harness. 
- Place the top strap above the hips of the jumper. 
- Close the buckle by putting one end into the other end of the buckle (like in a car seat); make sure the 
mechanism “lock”. 
- Tighten the strap around the hip, don’t tighten too much, and check the jumper feels comfortable. 
- The carabineer (safe snap links) should be on the outside and above the hips of the jumper. 
- If you cannot close the strap completely, use a smaller harness. 
- Put the leg straps around the legs. 
- Close the buckle and make sure it’s locked. 
- Tighten the strap around the leg and check the jumpers’ comfort!!! If the jumper does not fit in any of 
the harnesses, do not use COMBO!!! 
 
The harness should fit the jumper tightly, but not so tightly that it is uncomfortable. The harness straps 
should rest comfortably at the top of the thighs and around the buttocks. Make sure that the clothing of 
the jumper is not bunched or gathered beneath the straps. The instructor should ask the jumper how the 
harness feels and make sure that the jumper is comfortable and confident in the harness. The jumper 
should be told to voice any concerns with the harness and or his/her comfort at anytime during time on 
the COMBO. Should the harness become uncomfortable for the jumper during their time, instruct the 
jumpers to stop their movement and lower the winch down so the instructor can fix the harness. 
 
 
G. The Frame 
The aluminum poles and innovative design is what makes the COMBO unique. With this incredible 
layout, 3 jumpers can experience the fun at the same time. Make sure that the frame is clean and dry 
while operating the COMBO. Well maintained equipment lasts longer and gives a great impression. 
Be sure to secure all cables and bolts properly, see the construction manual for instructions. All binding 
units and connection points should be completely closed and secure and should be monitored 
throughout usage. All ropes connected to the frame should be straight and able to move freely through 
the pulleys. Stop the operation immediately if any of the above is malfunctioning! 
 
 
H. The Suspensions (trampolines) 
The suspensions are the elements of the COMBO Power Jump that allow the jumper to rebound and 
gain momentum by providing a bouncy cushion. Once the jumper is standing safe on the trampoline, 
attach the harness immediately like described above and then pull the winch up slightly at first to ensure 
the jumper does not fall off the trampoline. Make sure that the jumper is always connected to tightened
