1.4 SETUP
Tools equi ed: Socket set, Phillips Screwdriver, 9/16 open end wrench
Please read instructions carefully before assembly. Be sure to assemble the unit where it is to be used.
STEP 1
Remove the machine from packaging. Carefully lay out and count each part before
assembly. Refer to the parts list on page 5 of this manual.
STEP 2
Assemble the upright tube assembly to the base frame:
NOTE: This step could require two people.
1. Lay the upright tube assembly (A) on floor in front of base frame (B).
2. Connect the upper wire harness (C) to the lower wire harness (D). Insert connected plugs of the wire harnesses into wiring
hole on upright tube assembly (A).
3. Position the upright tube assembly (A) between the plates on the front of the base frame (B). Feed any excess wire harness
into the base frame.
4. Line up the holes on the plates with the holes on the upright tube assembly (A).
5. Connect the upright tube assembly (A) to the base frame (B) using four (#5) 2-3/4 bolts, eight (#9) washers (4 on each
side) and four (# ) low profile nylock nuts. DO NOT FULLY TIGHTEN AT THIS POINT.
CAUTION: The wire harness may obstruct the connecting holes. If this happens, gently pull on the end of the wire harness at
the top of the upright tube assembly (A) to clear the hole. Do not force the bolt through the hole if the wire harness is
obstructing the bolt, as damage to the wire harness my result.

6. Insert two (#4) 1 bolts and two (#9) washers into the
backside of the connector joint on the base frame (B). Start
each bolt, and then tighten with a 9/16 socket wrench.
. Tighten the four (#5) 2-3/4 bolts with a 9/16 socket
wrench.
8. Push the ten (#10) black plastic cover caps
over each (#5) 2-3/4 bolt head and (# ) low profile
nylock nut.

console. Make sure the connector snaps into place.
NOTE: #2 and #3 apply to model x3i only.
2. Plug the 3-pin connector at the end of the heart rate cable into the 3-pin (3P) connector in the back of the display console.
Make sure the connector snaps into place.
3. Plug in flat 6 pin (6P) connector for the Activity Zone.
4. Push excess cable(s) into the opening of the upright tube assembly (A).
STEP 4
Attach heart rate accessory tray to upright assembly:
NOTE: This step applies to model x3i only.
1. Before attaching the accessory tray (G), it is helpful to form the threads in the console plate (H). Using a #3 Phillips
screwdriver, start the (#0) self-tapping screws into the holes. When threads have formed, remove the screws.

1.5 HOW TOSTABILIZE THE LIFE FITNESS CROSS-TRAINER
After placing your Cross-Trainer where it will be used,
check its stability. If there is even a slight rocking motion,
or the unit is not stable, determine which stabilizing leg
is not resting firmly on the floor. To adjust the leg, loosen
the JAM NUT (A) and turn the STABILIZING LEG (B)
until the rocking motion ceases and both stabilizing legs
rest firmly on the floor. Retighten the JAM NUT.
NOTE: It is extremely important that the
stabilizing leg be correctly adjusted for
proper operation.
1.6 PLUGGING IN THE
CROSS-TRAINER
Your Life Fitness Cross-Trainer comes with a
standard U.S. power supply. Insert the power
adapter jack into the barrel plug on the back
of the Cross-Trainer. Then insert the
transformer into the wall outlet (or the
universal power supply if outside the U.S.).
Make sure the cord is placed so it doesnt
bind and will not be walked on. Check that
the console LEDs light up. If not, recheck the
plug and wall connections and make sure the
wall outlet has power.
