surface under the unit to protect the floor or carpet. Locate the treadmill a
few feet from walls or furniture. Keep the area behind the treadmill clear.

unsupervised around the treadmill.

tightened and secure. Do not use the treadmill if it is not completely
assembled or is damaged in any way.

• Wear proper exercise clothing and shoes for your workout—no loose
clothing. Do not wear shoes with heels or leather soles. Check the soles of
your shoes and remove any embedded stones. Tie long hair back.

with the use of the treadmill, secure the handrails into an upright position
by inserting the locking pins in place prior to walking or running on the
treadmill. Refer to the

• Keep your body and head facing forward. Do not attempt to turn around
on the treadmill when the belt is moving.

Tips for unpacking the treadmill:

• Ask for assistance to help you unpack the treadmill. Place the carton close
to the location where you plan to assemble and use the treadmill.

• To avoid scratching yourself or the unit, remove the staples when you
open the carton. Let the sides of the carton fall flat onto the floor.

CAUTION: The right handrail is
attached to the deck assembly
by the micro-adjustment
cable. Be sure to leave the
right handrail on top of the
running belt.

CAUTION: Avoid injury by
placing your hands on the side
rails when lifting the rear of
the treadmill. Do not use the
rear roller to lift the treadmill.

• To access the front lift bar and its cardboard packing, carefully lift the
black foam section of the right handrail (since its base is attached to the
treadmill by a cable). Remove the front lift bar and set it aside. Leave the
right handrail on top of the running belt.

• Remove the T-knob assembly by lifting the unsecured T-knob and sliding
the opposite end out of the cardboard slot.

• Have your assistant hold onto the side rails at the rear of the treadmill to
lift the deck while you pull the triangular, cardboard end block away from
the rear roller. Set the triangular, cardboard end block aside to use in
step 2 of the assembly instructions.

• Use a paper towel or a clean cloth to wipe off the excess lubricant on the
running belt and deck. Do not wipe off any lubricant that is between the
belt and the deck.

2. Install the Front Lift Bar Assembly. (Diagrams 3 and 4) With the treadmill
base flat on the floor near the location where you plan to use it, take the
following steps to install the front lift bar:

unpacked the treadmill, under the running belt and deck so that it
supports the front end of the unit and lifts the flywheel off of the
floor. See Diagram 3.

b. Remove the two bolts and washers from inside the front lift bar

bracket and set them aside.

c. Slide the front lift bar brackets into the side rail mounts and align the

lower bolt holes.

bolt through each safety stop.

g. Position the safety stop so that the metal spacer on the end of the

safety stop will be against the side rail. Insert a safety stop—one on
either side of the treadmill—into the side rail’s upper bolt hole as
shown in Diagram 4 and finger-tighten.

h. Securely tighten both the upper and lower mounting bolts into the

side rails using the hex key (E) provided.
