ASSEMBLY
Tohire an authorized service technician to assemble the treadmill, call tollfree 18004452480.
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 highperformance 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,
nonabrasive cleaner.
Assembly requires the included hex key      and your own phillips screwdriver                              .
Use the drawings below to identify the hardware used during assembly. Note: If a part is not in the parts bag,
check to see if it has been preattached to one of the parts to be assembled. To avoid damaging plastic
parts, do not use power tools for assembly.
