CHAPTER 2: PREVENTATIVE MAINTENANCE
What Kind Of Routine Maintenance Is Required?
We use sealed bearings throughout our ellipticals so lubrication is not needed. The most important
maintenance step is to simply wipe your perspiration off the trainer after each use.
How Do I Clean My Elliptical?
Clean with soap and water cleaners only. Never use solvents on plastic parts.
Cleanliness of your elliptical and its operating environment will keep maintenance 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)
Turn off the elliptical by unplugging the power cord from the wall outlet
• Wipe down the elliptical with a damp cloth. Never use solvents, as they can cause damage to the
elliptical.
• Inspect the power cord. If the power cord is damaged, contact Horizon Fitness.
• Make sure the power cord is not underneath the elliptical or in any other area where it can become
pinched or cut.
Weekly
Clean underneath the elliptical, following these steps:
• Turn off the elliptical
• Move the elliptical to a remote location.
• Wipe or vacuum any dust particles or other objects that may have accumulated underneath the
elliptical.
• Return the elliptical to its previous position.
Every Month
• Inspect all assembly bolts and pedals on the machine for proper tightness.
• Clean any debris off of the pedal arm wheels and guide rails.
Warning
To remove power from the elliptical, the power cord must be disconnected from the wall outlet.

3) Calories: Set goals for burning calories from 20 to 980 calories in 20 calorie increments.
You set your level to keep you in your fat burning zone.
4) Fat Burn: Relatively slow and steady is the name of the game to maximize your
weight-loss goals. Promote weight loss by increasing and decreasing the resistance, while keeping
you in your fat burning zone. Resistance changes, segments repeat every 60 seconds.
5) Hill Climb: Simulates a hill ascent and descent. This program helps tone muscle and
improve cardiovascular ability. Incline and resistance change and segments repeat every 60
seconds.

CHAPTER 3：CONSOLE INSTRUCTION
6) Target Heart Rate: This program is designed for you to improve your overall
cardiovascular fitness levels. You simply set your target heart rate. The program will then monitor
and adjust the intensity level to maintain your heart rate within your targeted range while you
exercise –a proven method to maximize your weight loss and fitness goals. A chest strap is
required and must be worn during the duration of this program. See below for calculating your
target heart rate:
Calculating Your Target Heart Rate
The first step in knowing the right intensity for your training is to find out your maximum heart rate (max
HR = 220 –your age). The age-based method provides an average statistical prediction of your max HR
and is a good method for the majority of people, especially those new to heart rate training.
The most precise and accurate way of determining your individual max HR is to have it clinically tested by a
cardiologist or exercise physiologist through the use of a maximal stress test. If you are over the age of 40,
overweight, have been sedentary for several years, or have a history of heart disease in your family, clinical
testing is recommended.
This chart gives examples of the heart rate range for a 30 year old exercising at 5 different heart rate zones.
For example, a 30-year-old’ s max HR is 220 –30 = 190 bpm and 90% max HR is 190 ×0.9 = 171 bpm.

their first 5k or simply begin an exercise routine. It is designed specifically to keep you motivated
and engaged, gradually building your strength, increasing your stamina and giving you the
confidence it takes to complete your first 5k.
8) Custom: Allows you to create and reuse your perfect workout with a combination of a
specific resistance, incline and time or distance. The ultimate in personal programming. This is a
time or distance based goal program.

CHAPTER 5：TROUBLESHOOTING
5.2 No Power To The Console
Symptom:
Console does not light up.
Reason:
1. Adaptor not correct or defective.
2. Console cable defective.
3. Console defective.
Solution:
1. The adaptor for this model is 12V -1A.Make sure to use the correct specification of an adaptor, and
replace the adaptor if it is defective.
2. A) First, try to re-connect the wires.
B) Test pin (1&2) of connector to see if voltage of console cable is 12V-1A(Fig A). If it is not, check if the
DC cable and ECB are connected well. If it’s needed, replace cables.
C) Check the wires in thr console to make sure they are all connected well.
Fig. A
(Console cable’s connectors with PCB)
If output is DC 12V, the console PCB defective. Replace the console set.

5.3 ECB Controller Instruction
1. Attach the steel cable here
2. Slip the orange block to adjust the resistance (left side is minimum and right side is MAX)

CHAPTER 5：TROUBLESHOOTING
5.4 No Rpm Display
Symptom:
No RPM shown on the console.
Reason:
1. Bad connection between the console cable and the console
2. Speed sensor wire defective
3. Magnet on the pulley is missing
4. Console defective
Solution:
1. Re-connect the console wire.
2. Check the gap between the speed sensor and magnet on pulley. It is normal within 5mm (Fig.
A).Adjust the gap if it is too large.
3. Re-install a new magnet (Fig. B).
4. Replace the console set.

CHAPTER 5：TROUBLESHOOTING
5.5 No Resistance Or Incorrect Resistance
Symptom：
1. The resistance is not adjustable during exercise.
2. The resistance is reverse or much too heavy.
Reason：
1. Speed sensor wire is defective.
2. Console cable or ECB motor is defective.
3. Steel rope of magnet system not correct.
4. Inside magnet defective.
Solution：
1. Turn on the console, and check the ECB motor.
In resistance level 1, the head of steel rope directs to top right side (around 45 degree).
If the head of steel rope directs to bottom left side, the resistance will be reversed, adjust the head
of steel rope to the correct position.
2. Press key “+” to adjust the resistance.
A) If ECB motor cannot move, the resistance will not be changed. The ECB motor or console cable is
defective. Check the console cable inserted in ECB motor. Re-connect the console cable first, if doesn’t
work, then change a new one. If nothing works, replace the ECB motor.

CHAPTER 5：TROUBLESHOOTING
5.5 No Resistance Or Incorrect Resistance
B) If the ECB motor can move, the resistance can be adjusted. If the resistance is still much too
heavy, check the gap between orange block and the bottom. It shall be within 1-2 mm.
If the gap is bigger than 1-2 mm, the resistance will be heavier than normal. Adjust the cable to the correct
gap range.
3. If all above conditions are OK, and the resistance is still much too heavy, the inside
magnet is defective. Replace the ECB Controller as the last step.
