18. With the assistance of at least a second person, flip the Base 

Assembly until the Walking Belt rests on the ground.

As the machine is flipped, the Lifting Shock will extend and 

pivot the Base Frame and Incline Frame Weldments. Be sure 

to be clear of any pinch opportunities and not to grasp the 

Base Assembly from these shifting parts. Do not grasp the 

Walking Belt since it can abruptly move.

Note: the following image shows the Base Assembly on the side, 

not fully flipped and resting flat on the Walking Belt. The Uprights are 

also still attached.

19. Using a 13mm wrench and a 6mm hex wrench, remove the 

indicated hardware (with oval) from the Incline Motor Assembly and 

the Incline Weldment.

20. Using a 13mm wrench and a 6mm hex wrench, remove the 4 

screws (with arrows) from the Deck Frame and the old Incline Weld-

ment.

Be aware that when the Hardware is released from the Deck 

Frame, the Base Frame Weldment may abruptly move since it 

will only be supported by the Lift Shock. Be sure to keep clear 

of any potential pinch opportunities.

21. Using a 13mm wrench and a 6mm hex wrench, attach the new 

Incline Weldment to the Deck Frame.

22. Using a 13mm wrench and a 6mm hex wrench, re-attach the 

Incline Weldment to the Incline Motor Assembly.

23. With the assistance of at least a second person, flip the Base 

Assembly to the Upright position. Be aware that the Lifting Shock will 

begin to compress when placed back to an upright position, lowering 

the Base Assembly.

Be sure the area is clear around the Base Assembly before 

flipping it. Do not grasp the Walking Belt since it can abruptly 

move.
