ARE THE SOUNDS MY ELLIPTICAL MAKES NORMAL?

Our ellipticals 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 ellipticals. 

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 ELLIPTICAL 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 background 

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 TRAINER EASILY ONCE IT IS ASSEMBLED?

Your elliptical has a pair of transport wheels built into the front legs. It is easy to move your elliptical by 

rolling it on the front transport wheels. It is important that you place your elliptical in a comfortable and 

inviting room. Your elliptical is designed to use minimal floor space. Many people will place their ellipticals 

facing the TV or a picture window. If at all possible, avoid putting your elliptical in a unfinished basement. 

To make exercise a desirable daily activity for you, the elliptical should be in a comfortable setting.

CAN I PEDAL BACKWARDS ON MY ELLIPTICAL?

Your elliptical allows you to pedal both forward and backwards to exercise and strengthen a wider range 

of muscles.

COMMON PRODUCT QUESTIONS

PROBLEM:

 There is no heart rate reading.

SOLUTION:

 Remove the console and verify that the heart rate cables are attached properly, making 

sure that the cables are securely inserted into the console.

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.

NOTE: 

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.

If the above troubleshooting section does not remedy the problem, discontinue use and turn the power off.

CALL CUSTOMER TECH SUPPORT AT THE NUMBER ON THE BACK PANEL 

WHEN YOU ARE NEAR THE EQUIPMENT.

The following information may be asked of you when you call. Please have these items readily available:

•  Model Name

•  Serial Number

•  Date of Purchase (receipt or credit card statement)

In order for Customer Tech Support to service your elliptical they may need to ask detailed questions about the 

symptoms that are occurring. Some troubleshooting questions that may be asked are:

•  How long has this problem been occurring?

•  Does this problem occur with every use? With every user?

•  If you are hearing a noise, does it come from the front, back or inside? What kind of noise is it (thumping, 

grinding, squeaking, chirping etc.)?

•  If you are having a resistance problem what is occurring? Is the resistance always too hard or too easy? 

Does the resistance respond when pushing the buttons on the console? Does the resistance constantly cycle 

through the levels during the workout?

•  Has the machine been maintained per the maintenance schedule?

• Does the problem occur when using the handlebars? Without using the handlebars?

Answering these and other questions will give the technicians the ability to send proper replacement parts and 

the service necessary to get you and your Horizon Fitness elliptical running again!
