WHAT KIND OF ROUTINE MAINTENANCE IS REQUIRED?
We use sealed bearings throughout our bikes so lubrication is not needed. The most important main-
tenance step is to simply wipe your perspiration off the bike after each use.
HOW DO I CLEAN MY HORIZON FITNESS RECUMBENT BIKE?
Clean with soap and water cleaners only. Never use solvents on plastic parts.
Cleanliness of your Horizon Fitness recumbent bike and its operating environment will keep mainte-
nance problems and service calls to a minimum. For this reason, Horizon Fitness recommends that
the following preventive maintenance schedule be followed.
AFTER EACH USE (DAILY)
•Wipe off the recumbent bike with a clean rag or towel.
•Never use solvents, as they can cause damage to the recumbent bike.
EVERY WEEK
Clean underneath the recumbent bike, following these steps:
•Move the recumbent bike to a remote location.
•Wipe or vacuum any dust particles or other objects that may have accumulated underneath the
recumbent bike.
•Return the recumbent bike to its previous position.
EVERY MONTH
•Inspect all assembly bolts and pedals on the machine for proper tightness.
Maintenance & Troubleshooting Procedures

17
Your Horizon Fitness recumbent bike is designed to be reliable and maintenance free. However, if you
do experience problems with your recumbent bike, please reference the troubleshooting guide listed
below.
PROBLEM: There is no display on the console.
SOLUTION: Replace the batteries located on the back side of the console and confirm they are prop-
erly installed.
PROBLEM: The recumbent bike makes a squeaking or chirping noise.
SOLUTION: Loosen all bolts attached during the assembly process, grease the threads and tighten
again.
PROBLEM: The resistance levels seem to be incorrect, seeming too hard or too easy.
SOLUTION: Confirm proper installation of tension knob, making sure the tension cable is tight.

18
PROBLEM: Erratic or inconsistent heart rate readout.
SOLUTION: Check your exercise environment for sources of interference such as high power lines,
large motors, etc. Outside interference sources such as computers, motors and fluorescent lights may
cause the heart rate reading to be erratic.
You may experience an erratic readout under the following conditions:
•Gripping the heart rate handlebars too tight. Try to maintain moderate pressure while holding onto
the heart rate handlebars.
•Constant movement and vibration due to constantly holding the heart rate grips while exercising.
•When you are breathing heavily during a workout.
•When your hands are constricted by wearing a ring.
•When your hands are dry or cold. Try moistening your palms or rubbing them together to warm.
•Anyone with heavy arrhythmia.
•Anyone with arteriosclerosis or peripheral circulation disorder.
•Anyone whose skin on the measuring palms is especially thick.
If you have any questions, or if there are any missing parts, we will guarantee complete satisfaction.

ARE THE SOUNDS MY RECUMBENT BIKE MAKES NORMAL?
Our recumbent bikes are some of the quietest available because they use belt drives and friction free
magnetic resistance. We use the highest grade bearings and belts to minimize noise. However,
because the resistance system itself is so quiet, you will occasionally hear other slight mechanical
noises. Unlike older, louder technologies, there are no fans, friction belts, or alternator noises to
mask these sounds on our recumbent bikes. These mechanical noises, which may or may not be
intermittent, are normal and are caused by the transfer of significant amounts of energy to a rapidly
spinning flywheel. All bearings, belts and other rotating parts will generate some noise which will
transmit through the casing and frame. It is also normal for these sounds to change slightly during a
workout and over time because of thermal expansion of the parts.
WHY IS THE RECUMBENT BIKE I HAD DELIVERED LOUDER THAN THE ONE AT THE STORE?
All fitness products seem quieter in a large store showroom because there is generally more back-
ground noise than in your home. Also, there will be less reverberation on a carpeted concrete floor
than on a wood overlay floor. Sometimes a heavy rubber mat will help reduce reverberation through
the floor. If a fitness product is placed close to a wall, there will be more reflected noise.
HOW LONG WILL THE DRIVE BELT LAST?
The computer modeling we have done indicated virtually thousands of maintenance free hours. Belts
are now commonly used in far more demanding applications such as motorcycle drives.
CAN I MOVE THE RECUMBENT BIKE EASILY ONCE IT IS ASSEMBLED?
Your Horizon Fitness recumbent bike has a pair of transport wheels built into the front foot. It is easy
to move your recumbent bike by rolling it on the front transport wheels. It is important that you place
your Horizon Fitness recumbent bike in a comfortable and inviting room. Your recumbent bike is
designed to use minimal floor space. Many people will place their recumbent bikes facing the TV or a
picture window. If at all possible, avoid putting your recumbent bike in a unfinished basement. To
make exercise a desirable daily activity for you, the recumbent bike should be in a attractive setting.
Common Product Questions

20
Always consult your physician before beginning an exercise program.
HOW OFTEN?
The American Heart Association recommends that you exercise at least 3 to 4 days per week to main-
tain cardiovascular fitness. If you have other goals such as weight or fat loss, you will achieve your goal
faster with more frequent exercise. Whether it’s 3 days or 6 days, remember that your ultimate goal
should be to make exercise a lifetime habit. Many people are successful staying with a fitness program
if they set aside a specific time of day to exercise. It doesn’t matter whether it’s in the morning before
your shower, during lunch hour or while watching the evening news. What’s more important is that it’s
a time that allows you to keep a schedule, and a time when you won’t be interrupted. If you are to be
successful with your fitness program, you have to make it a priority in your life. So decide on a time,
pull out your day planner and pencil in your exercise times for the next month!
HOW LONG?
For aerobic exercise benefits, it’s recommended that you exercise from between 24 and 32 minutes per
session. But start slowly and gradually increase your exercise times. If you’ve been sedentary during the
past year, it may be a good idea to keep your exercise times to as little as five minutes initially. Your
body will need time to adjust to the new activity. If your goal is weight loss, a longer exercise session
at lower intensities has been found to be most effective. A workout time of 48 minutes or more is rec-
ommended for best weight loss results.
