Step 2
While standing on the treadmill, hold onto the center cross bar located
on the console. Carefully lift up and backwards, lifting the uprights into
place.
Do so until you hear the pop pin click. This clicking sound signifies that
the left upright is locked into place. This is done to prevent any injury
while proceeding to the following steps.
Align the holes on the treadmill to the holes on the uprights. Secure the
uprights by using two washers 9*22*2 and two allen bolts M8*15 on
each side. Note: Make sure the left upright is all the way back before
installing hardware. Do not overtighten bolts.
