ProForm LX 660, User Manual

ASSEMBLY

Assembly requires two people. Set the treadmill in a cleared area and remove all packing materials. Do not
dispose of the packing materials until assembly is completed. Assembly requires your own Phillips screw-
driver                        and rubber mallet                   .

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 performance. 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.

1. With the help of a second person, carefully raise the

treadmill to position shown. 

While a second person tips the treadmill to one side
slightly and holds it, insert one of the Extension Legs (103)
into the treadmill as shown. Make sure that the Extension
Leg is turned so the Thick Base Pad (97) is on the bottom. 

Next, tip the treadmill to the other side and insert the
other Extension Leg (not shown) in the same way. Lower
the side of the treadmill so that both Extension Legs
(103) are resting flat on the floor. 

2. With the help of a second person, carefully lower the

treadmill frame and then tip the Uprights (82) down as
shown. Note: It may be helpful to place your foot on the
wheel as you tip the Uprights. Make sure that the
Extension Legs (103) remain in the Uprights.

Attach each Extension Leg (103) with two Screws (101)
and a Base Pad (119) as shown. 

Note: One replacement Base Pad (119) and Spacer (not
shown) may be included. If a Base Pad becomes worn
and needs to be replaced, use the replacement Base
Pad. If a Thick Base Pad (97) needs to be replaced, use
the replacement Base Pad with the Spacer.
