COMMON PRODUCT QUESTIONS
ARE THE SOUNDS MY TREADMILL MAKES NORMAL?
All treadmills make a certain type of thumping noise due to the belt riding over the rollers, especially new
treadmills. This noise will diminish over time, although may not totally go away. Over time, the belt will stretch,
causing the belt to ride smoother over the rollers.
WHY IS THE TREADMILL I PURCHASED 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.
WHEN SHOULD I BE WORRIED ABOUT A NOISE?
As long as the sounds your treadmill makes are no louder than a normal conversational tone of voice, it is
considered normal noise.
TROUBLESHOOTING - TREADMILL
Your treadmill is designed to be reliable and easy to use. However, if you experience a problem, please reference the
troubleshooting guide listed below.
PROBLEM:
The console does not light up and/or the belt does not move.
SOLUTION:
Verify the following:
DOES THE RED LIGHT ON THE ON/OFF SWITCH LIGHT UP?
IF YES:
• Double check that all connections are secure, especially the console cable. Unplug and reconnect the console
cable to verify.
• Make sure the console cable is not pinched or damaged in any way.
• Turn the power off, unplug the power cable and wait 60 seconds. Remove motor cover. Wait until all red LED lights
have gone off on the motor control board before proceeding. Next, verify that none of the wires connected to the
lower board are loose or disconnected.
IF NO:
• Verify that the outlet the machine is plugged into is functional. Double check that the breaker has not tripped, it is
on a dedicated 20-amp circuit, it is not on a GFCI equipped outlet, and it is not plugged into a power strip/surge
protector or extension cord.
• The power cord is not pinched or damaged and is properly plugged into the outlet AND the machine.
• The power switch is turned to the ON position.
PROBLEM:
The treadmill circuit breaker trips during a workout.
SOLUTION:
Verify the following:
• Make sure the treadmill is plugged into a dedicated 20-amp circuit.
• Verify that you do not have the machine on an extension cord or surge protector.
• Confirm that the machine is not plugged into a GFCI-equipped outlet or on a circuit that has a GFCI-equipped outlet on
it.
PROBLEM:
The running belt does not stay centered during a workout.
SOLUTION:
Verify the following:
• Make sure the treadmill is on a level surface.
• Verify that the belt is properly tightened and centered (Refer to the Adjustment section for detailed directions).
TROUBLESHOOTING
PROBLEM:
Operating speed appears inaccurate.
SOLUTION:
Auto-calibrate the treadmill:
• Power on the treadmill and have the safety key in position on the
console. Press and hold the elevation “+” and speed “-” buttons for
approximately 5 seconds to enter the Engineering Mode. The console
will beep and “ENG0” appears in the display.
• Press the Speed “+” or “-” button until “ENG2” appears in the display.
• Press, “ENTER” to select. Press, “START” to begin. The treadmill
running belt will begin to move automatically and the auto-calibration
sequence will properly set and store the speed values.
• Upon successful calibration, the treadmill will beep several times. The
console will automatically exit Engineering Mode and return to the
start-up screen.
TROUBLESHOOTING - HEART RATE
Check your exercise environment for sources of interference such as fluorescent lights, computers, underground fencing, home
security systems or appliances containing large motors. These items may cause erratic heart rate readouts.
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 handlebars while exercising. If you are receiving
erratic heart rate readouts, try to only hold the grips long enough to monitor your heart rate.
• 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 to moisten your palms by rubbing them together to warm.
• Anyone with heavy arrhythmia.
• Anyone with arteriosclerosis or peripheral circulation disorder.
• Anyone whose palm skin is especially thick.
If the above troubleshooting section does not remedy the problem, discontinue use and turn the power off, and
contact Sears for service at 1-800-4-MY-HOME
®
.
The following information may be asked of you when you call. Please have these items readily available:
• Model Name
• Serial Number
In order for the technician to service your treadmill 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 or the back? What kind of noise is it (thumping, grinding, squeaking,
chirping etc.)?
• Has the machine been lubricated and maintained per the maintenance schedule?
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 treadmill running again!
WARNING
DO NOT
stand on running belt while
calibrating – stand on the guide
rails. Treadmill will fluctuate between
low and high speeds for several
minutes until calibration is complete.
