1. FRAME ASSEMBLY
A. Place the legs in the desired location and stand them upright so that the plastic
caps are on the floor (Fig. 1). The legs will run perpendicular to the length of
the Tumbl Trak™ like railroad ties. Space the legs out approximately 5’ 6”
apart from each other. Two legs will be used for every 10’ of Tumbl Trak™
Frame.
B. Insert the down tubes of the 10' rails into the legs. The spring holes should face
the inside of the Tumbl Trak™. (See Fig. 2 & Fig. 5-next page).
C. Match the host and guest ends (See Fig. 3) of the rails and insert the bolts to fasten
together (See Fig. 4).
D. If you purchased Downhill Inclines with your Tumbl Trak™, please see the Assembly
Instructions that were included with that packaging.
2. SPRINGING THE BED
A. Decide which end of the bed will be used as the “take off” or dismount end. Start
springing the bed on this end. **The “take-off end”is where the athletes dismount
onto a mat.
B. Hook two springs on the first D-ring (the silver rings that are sewn along the edges of the
bed). Using the Spring Tool, attach the first and second springs to the first two spring
holes respectively (See Fig. 5-next page).
C. The third spring will attach to the second D-ring and hook to the third frame hole (See
Fig. 6-next page). ALWAYS ATTACH HOOKS DOWNWARDS!!!
D. Repeat on the other side.
E. As you continue springing the bed, skip the tenth frame hole to angle the springs, pulling
the bed tight and smooth (See Fig. 6 & 7-next page). DO NOT skip every 10 holes (20th,
30th, 40th, etc) - only the 10th hole. As you continue springing the bed, if you notice that
the springs are no longer angled or that wrinkles are starting to form on the bed, then skip
another set of frame holes. When the bed is attached properly, it should be smooth and
tight. WARNING: Tumbl Trak™cannot be held responsible for beds that are not strung
up according to these instructions.
F. Springing the bed will be much easier and quicker if you have another person hand
springing the opposite side of the Tumbl Trak™while you are using the Spring Tool to
spring one side. When hand springing the opposite side of the Tumbl Trak™, be sure to
stay at least 4-5 springs ahead of the person using the Spring Tool.
G. If you are setting up the Tumbl Trak™by yourself, hand spring 4-9 springs on one side
then alternate to the other side and continue to use the Spring Tool to spring the 2-7
springs before you alternate to the other side again. By continuing down the bed further on
the hand sprung side, the amount of effort to hand spring will remain low.
