Horizon Fitness Treadmill 

Running Belt Adjustments 
Tensioning the Running Belt:

If you can feel a slipping sensation when running on the treadmill, the running belt must be tightened. In most cases, the belt has stretched from use, causing the belt to slip.
This is a normal and common adjustment. To eliminate this slipping, tension both the rear roller bolts with the appropriate sized Allen wrench, turning both the left and right bolt 1/4 TURN as shown below. Try the treadmill again to check for slipping. Repeat if necessary, but NEVER TURN the roller bolts more than 1/4 turn at a time.
NOTE: The belt tension is set properly when the running belt is ¼ of an inch from the deck, towards the rear roller.
Aligning the Running Belt:
If the running belt moves rapidly to one side when performing the next step, press the Stop button immediately.
Turn on the treadmill. With the treadmill speed between 6-8 mph, stand behind the treadmill and watch the movement of the running belt. As you watch the running belt, make sure that the belt runs without moving from one side to the other and that the belt is centered between the side rails.
If the running belt is not tracking properly follow the following procedures:
If the running belt tracks to the left, turn the left roller bolt clockwise ¼ of a turn, keeping the belt tension in mind. Over-tightening the running belt may cause damage to the running belt and roller bearings.
If the running belt tracks to the right, turn the right roller bolt clockwise ¼ of a turn, keeping the belt tension in mind. Over-tightening the running belt may cause damage to the running belt and roller bearings.
Tensioning the Drive Belt
Quantum II, Omega II, Advance 200 & 300
Procedure:

1. Turn off the power to the treadmill and remove the power cord from the wall outlet.
2. With a Philips head screwdriver, remove the motor cover.
3. Unplug the motor wires from the lower board.
4. Before continuing, it is a good idea to weight down the treadmill deck to prevent the treadmill from springing up. Removing the weight of the motor will significantly reduce the weight in the front end of the treadmill.
5. With a 13mm wrench, loosen the attachment nuts (M08) and washers (M09) holding the motor to the frame.
6. With a 6mm Allen wrench, loosen the two motor bracket attachment bolts (M45, M46) and adjust to proper position.
7. Tighten the two motor attach bolts (M45, M46) with a 6mm Allen wrench.
8. Verify the proper tension on the drive belt. Using a timing belt tension gauge, the proper tension should be between 65 to 75 lbs. If a timing belt tension gauge is not available, the drive belt should have approximately 3/8 of inch deflection. If the drive belt tension is not set properly, loosen the motor attachment bolts and adjust.
DIAGNOSIS PROCESS
The following steps are provided as routine checkpoints when diagnosing problems on a Horizon Fitness treadmill. If followed correctly, these checkpoints should help diagnosis the majority of problems that may be encountered.
1. Proper supplying power to treadmill.
# Make sure the treadmill is not on an extension cord. Extension cords create energy loss, which prevents proper voltage from being supplied to the treadmill.
# Make sure the treadmill is on a dedicated circuit. Horizon Fitness recommends a 20 amp dedicated circuit, but a 15 amp dedicated circuit may be sufficient.
# Make sure that proper voltage is being supplied from the wall outlet. Warning! Hazardous voltages will be tested in the following procedure. Exercise extreme caution when performing these procedures. Do not connect or disconnect any wiring, connectors, or other components with the power applied to the treadmill.
# Disconnect the treadmill power cord from the wall outlet. Using an AC voltmeter, verify that the proper AC voltage is present at the wall outlet. Nominal 120 volts AC may vary between approximately 105 volts AC and 135 volts AC.
2. Proper Wiring
# Verify that all wires are secure and attached in the correct position (reference wiring diagrams in table of contents).
# Verify that there aren’t any pinches or cuts in any of the wires, especially the console cable connecting from the lower board to the upper board. Replace and wires that are pinched or cut.
3. Proper Sensor Wire Function
# Verify that the rpm sensor wire is positioned as close to the front roller pulley as possible. The factory standard is a distance or 2-4 mm between the sensor wire and the front roller pulley. Loosen the sensor bracket attachment screws and position sensor bracket closer to front roller pulley if the distance is greater than 2-4 mm.
# Verify that the sensor wire is attached to the sensor bracket properly. The proper position would be so that the sensor wire is protruding from the left hand side of the sensor and sensor bracket while facing the treadmill.
Verify that the rpm magnet is positioned in the front roller pulley.
Verify that the lower control board is outputting the proper voltage (5 volts DC). See Voltage checkpoints in table of contents for voltage measurement instructions.
# Verify that the sensor wire is functioning properly in Diagnostics Mode. To enter Diagnostics Mode, follow the directions below:
Omega II, Advance 200
# Press and hold the Elevation ‘Up’ and Speed ‘Down’ buttons simultaneously for five seconds. The upper board should beep and the software version should be displayed in the Time window.
# Press Start. The treadmill motor should begin moving. The Speed window will display the actual speed of the treadmill, which correlates with the start speed in a normal program (0.5 mph). If the treadmill speed is incorrect, adjust the speed dial located on the lower board.
Alpine/Paragon II/Quantum II, Advance 500/400/300
# Press and hold the Elevation ‘Up’ and Speed ‘Down’ buttons simultaneously for five seconds. The upper board should beep and the software version should be displayed in the Calories/Elevation window.
# Press Start. The treadmill motor should begin moving. The Speed/Pulse window will display the actual speed of the treadmill, which correlates with the start speed in a normal program (0.5 mph). If the treadmill speed is incorrect, adjust the speed dial located on the lower control board.
4. Proper Speed Calibration.
# Press Start. Verify that the treadmill motor begins moving within 1 second. If the treadmill motor begins hesitates and starts moving after 1 second, adjust the speed dial located on the lower control board.
# Verify that the treadmill motor turns smoothly. There should not be any jerky or choppy movement of the motor. It may also be necessary to stand on the belt at a slow speed and ride the treadmill belt from the front roller to the rear roller to verify that the treadmill motor and running belt are traveling smoothly.
# Verify start up speed (0.5 mph) in Diagnostics Mode.

3 Press Start. The treadmill motor should begin moving. The Speed/Pulse window will display the actual speed of the treadmill, which correlates with the start speed in a normal program (0.5 mph). If the treadmill speed is incorrect, adjust the speed dial located on the lower control board (see speed calibration in table of contents).
# The start speed of the treadmill can also be determined by counting the revolutions/minute of the running belt. At 0.5 mph, the treadmill belt should make 4 revs/minute for the Alpine & Advance 500 and 4.5 revs/minute for the Paragon II, Quantum II, Omega II, Advance 200, 400 & 500 treadmills. If the belt revolutions are incorrect, adjust the speed dial located on the lower control board (see speed calibration in table of contents).
