WARNING: To reduce the risk of serious injury, read all important precautions and
instructions in this manual and all warnings on your elliptical before using your elliptical. ICON
assumes no responsibility for personal injury or property damage sustained by or through the
use of this product.
IMPORTANT PRECAUTIONS
1. It is the responsibility of the owner to ensure
that all users of the elliptical are adequately
informed of all precautions.
2. Before beginning any exercise program,
consult your physician. This is especially
important for persons over age 35 or per-
sons with pre-existing health problems.
3. The elliptical is not intended for use by
persons with reduced physical, sensory, or
mental capabilities or lack of experience and
knowledge, unless they are given supervi-
sion or instruction about use of the elliptical
by someone responsible for their safety.
4. Use the elliptical only as described in this
manual.
5. The elliptical is intended for home use only.
Do not use the elliptical in a commercial,
rental, or institutional setting.
6. Keep the elliptical indoors, away from mois-
ture and dust. Do not put the elliptical in a
garage or covered patio, or near water.
7. Place the elliptical on a level surface, with at
least 3 ft. (0.9 m) of clearance in the front and
rear of the elliptical and 2 ft. (0.6 m) on each
side. To protect the floor or carpet from dam-
age, place a mat under the elliptical.
8. Inspect and properly tighten all parts each
time the elliptical is used. Replace any worn
parts immediately. Use only manufacturer-
supplied parts.
9. Keep children under age 16 and pets away
from the elliptical at all times.
10. The elliptical should not be used by persons
weighing more than 275 lbs. (125 kg).
11. Wear appropriate clothes while exercising;
do not wear loose clothes that could become
caught on the elliptical. Always wear athletic
shoes for foot protection while exercising.
12. Hold the handlebars or the upper body arms
when mounting, dismounting, or using the
elliptical. Before mounting or dismounting,
bring the pedals to a stop with the pedal
on the mounting or dismounting side in its
lowest position.
13. The elliptical does not have a freewheel; the
pedals will continue to move until the fly-
wheel stops. Reduce your pedaling speed in
a controlled way.
14. Keep your back straight while using the ellip-
tical; do not arch your back.
15. Over exercising may result in serious injury
or death. If you feel faint, if you become short
of breath, or if you experience pain while
exercising, stop immediately and cool down.

HOW TO PLUG IN THE POWER ADAPTER
IMPORTANT: If the elliptical has been exposed to
cold temperatures, allow it to warm to room tem-
perature before you plug in the power adapter (A).
If you do not do this, you may damage the console
displays or other electronic components.
Plug the power
adapter (A) into
the receptacle on
the front of the
elliptical. Insert
the appropriate
plug adapter into
the power adapter
if necessary.
Then, plug the
power adapter into an appropriate outlet that is prop-
erly installed in accordance with all local codes and
ordinances.
HOW TO LEVEL THE ELLIPTICAL
If the elliptical rocks slightly on your floor during use,
turn one or both of the leveling feet (B) beneath the
rear of the frame or turn the leveling foot (C) under
the center of the frame until the rocking motion is
eliminated.
HOW TO MOVE THE ELLIPTICAL
Due to the size and weight of the elliptical, moving
it requires two persons. Stand in front of the elliptical,
hold the upright (D), and place one foot against one
of the wheels (E). Next, pull on the upright and have a
second person lift the handle (F) until the elliptical will
roll on the wheels. Carefully move the elliptical to the
desired location, and then lower it to the floor.

HOW TO CHANGE THE INCLINE OF THE RAMP
To vary the motion of
the pedals, you can
change the incline
of the ramp. To raise
the ramp, press the
latch button (G), and
then pull the ramp
handle (H) upward
to the desired incline
level.
To lower the ramp, press the latch button (G), pull the
ramp handle (H), and lower the ramp to the desired
incline level. Then, release the latch button and
engage the latch pin into one of the adjustment holes
in the frame. Make sure that the latch pin is firmly
engaged in one of the adjustment holes in the
frame.
HOW TO EXERCISE ON THE ELLIPTICAL
To mount the elliptical, hold the handlebars (I) or the
upper body arms (J) and step onto the pedal (K) that is
in the lower position. Then, step onto the other pedal.
Push the pedals until they begin to move with a con-
tinuous motion. Note: The pedals can turn in either
direction. It is recommended that you turn the ped-
als in the direction shown by the arrow; however,
for variety, you can turn the pedals in the opposite
direction.
To dismount the elliptical, wait until the pedals (K)
come to a complete stop. Note: The elliptical does
not have a free wheel; the pedals will continue to
move until the flywheel stops. When the pedals are
stationary, step off the higher pedal first. Then, step off
the lower pedal.
