ASSEMBLY
Assembly requires two persons. Set the treadmill in a cleared area and remove all packing materials. Do not
dispose of the packing materials until assembly is completed. Note: The underside of the treadmill walking
belt is coated with high-performance lubricant. During shipping, a small amount of lubricant may be transferred to
the top of the walking belt or the shipping carton. This is a normal condition and does not affect treadmill perfor-
mance. If there is lubricant on top of the walking belt, simply wipe off the lubricant with a soft cloth and a mild,
non-abrasive cleaner.
Assembly requires the included hex keys_t and your own Phillips screwdriver (:_:] ..................,
adjustable wrench o__-- _, scissors 8 _-=_-_, and rubber malet (_ _.
Use the drawings below to identify the assembly hardware. The number in parentheses below each drawing is
the key number of the part, from the PART LIST near the end of this manual. The number after the parentheses
is the quantity needed for assembly. Note: If a part is not in the hardware kit, check to see if it is preattached to
one of the parts to be assembled. To avoid damaging plastic parts, do not use power tools for assembly.
