3/4” wrenches (2x)
Two 8”-12” jack stands (or support blocks)

Adding grease to the foot shaft ball socket joint
Tip:
It is recommended that two technicians are utilized for facilities with multiple machine repairs.
1
Switch the power OFF and unplug the power cord.
2
Place wheel stops in front of the treadmill front wheels to prevent forward movement (fig. 1).
3
Place a scissor jack underneath the center of the rear frame crossmember (fig. 1). Then raise the rear of the
treadmill enough to allow removal of the plastic foot pad (approx. 4”-6” above the bottom of the foot pad).
